• How can I rename by CarrierWave file versions?

  - by AKWF

  Upon the uploading of an image in my application, 4 different sizes are created and saved using CarrierWaves version functionality. However, I am converting all of these versions to JPEG. The source file that is uploaded remains unchanged. So I can upload a TIFF file, and CarrierWave will create :large, :medium, :small, and :thumb versions. My problem is that these files all still end in .tif. Yet they are indeed JPEG files, as I've verified this with the file command. How can I write the filenames correctly for each version, and ensure that CarrierWave will report each version's name correctly?

• sharepoint online quick launch

  - by Brian

  Hello, we are converting from sharepoint 2003 to sharepoint on line. I am having trouble reproducing a specific behavior in the online version. If a choose a list, I get a "select a view" navigation on the left hand side of the page showing the available views. When a new view is created, it automatically appears on this navigation list. In the online sharepoint, instead there is a view dropdown. I know I can manually setup links on the quick launch but I'm looking for an automatic way to do this. Can the online sharepoint be set up so that when views are added they automatically appear as left-hand links? Or can the "views" dropdown be moved to the left side which would be an acceptable work around? Please note I am unfamiliar with SP designer and I do work with .NET but I dont want to go that route just for this issue - thanks.

• can oracle types be updated like tables?

  - by Omnipresent

  I am converting GTT's to oracle types as explained in an excellent answer by APC. however, some GTT's are being updated based on a select query from another table. For example: UPDATE my_gtt_1 c SET (street, city, STATE, zip) = (SELECT src.unit_address, src.unit_city, src.unit_state, src.unit_zip_code FROM (SELECT mbr.ROWID row_id, unit_address, RTRIM(a.unit_city) unit_city, RTRIM(a.unit_state) unit_state, RTRIM(a.unit_zip_code) unit_zip_code FROM table_1 b, table_2 a, my_gtt_1 mbr WHERE type = 'ABC' AND id = b.ssn_head AND a.h_id = b.h_id AND row_id >= v_start_row AND row_id <= v_end_row) src WHERE c.ROWID = src.row_id) WHERE state IS NULL OR state = ' '; if my_gtt_1 was not a global temporary table but an oracle collection type then is it possible to do updates this complex? Or in these cases we are better off using the global temporary table?

• iPad: How Do I Limit the Number of Tabs in UITabBarController?

  - by Chris_K

  I'm converting an iPhone app to a universal app, which leaves me with a UITabBarController as the root view controller for a UISplitViewController. That is, the tab bar appears at the bottom of the left-hand view when the iPad is in landscape mode. On the iPhone, the system automatically limited the number of tabs shown in the tab bar to 5. But on the iPad simulator (which is all I have at the moment), my tab bar has 8 tabs, including the More tab. What gives? Thanks. Update: Since I had no luck finding an answer to this question, I gave up on using a tab bar interface in my iPad-flavored app. Instead, I added one more level to the navigation controller drill-down. That ends up working fine for this app.

• AbsoluteTime with numeric argument behaves strangely.

  - by dreeves

  This is strange: DateList@AbsoluteTime[596523] returns {2078, 7, 2, 2, 42, 9.7849} But DateList@AbsoluteTime[596524] returns {1942, 5, 26, 20, 28, 39.5596} The question: What's going on? Note that AbsoluteTime with a numeric argument is undocumented. (I think I now know what it's doing but figured this is useful to have as a StackOverflow question for future reference; and I'm curious if there's some reason for that magic 596523 number.) PS: I encountered this when writing these utility functions for converting to and from unix time in Mathematica: (* Using Unix time (an integer) instead of Mathematica's AbsoluteTime... *) tm[x___] := AbsoluteTime[x] (* tm is an alias for AbsoluteTime. *) uepoch = tm[{1970}, TimeZone->0]; (* unixtm works analogously to tm. *) unixtm[x___] := Round[tm[x]-uepoch] (* tm & unixtm convert between unix & *) unixtm[x_?NumericQ] := Round[x-uepoch] (* mma epoch time when given numeric *) tm[t_?NumericQ] := t+uepoch (* args. Ie, they're inverses. *)

• How can I test if a point lies within a 3d shape with its surface defined by a point cloud?

  - by Ben

  Hi I have a collection of points which describe the surface of a shape that should be roughly spherical, and I need a method with which to determine if any other given point lies within this shape. I've previously been approximating the shape as an exact sphere, but this has proven too inaccurate and I need a more accurate method. Simplicity and speed is favourable over complete accuracy, a good approximation will suffice. I've come across techniques for converting a point cloud to a 3d mesh, but most things I have found have been very complicated, and I am looking for something as simple as possible. Any ideas? Many thanks, Ben.

• Ruby: wait for system command to end

  - by Ignace

  Hey all, I'm converting an xls 2 csv with a system(command) in ruby. After the conversion i'm processing this csv files. But the conversion is still going when the program wants to process the files. So at that time they are non existant. Can someone tell me if it's possible to let Ruby wait the right amount of time for the system command to finish? Right now i'm using sleep 20 but if it will take longer once, it isn't right of course... Thanks!

• fieldset form with Table-like layout with CSS?

  - by Scott B

  I have an application in which I'm currently using a two column table in order to get accurate cell alignment of the left column labels/descriptions with the right column form fields. I'd like to convert it to css and use jQuery to expand/collapse specific sections. I've seen some jQuery libraries, the menu.js in particular. And they appear to all use list items for the markup. I'm OK with converting my table to UL/LI structure if that's what I need to do. Just looking for some advice.

• Security Token/Cross Domain Cookie in Classic ASP?

  - by jlrolin

  I have an interesting conundrum. We have a site that is a completely separate domain, we'll say http://www.x.com and our own site that is http://www.y.com. The y.com site is actually a classic ASP site, and we aren't converting it to .NET at this time. The problem is that there is a link on x.com that redirects to y.com from a members area. We want to "authenticate" the user to make sure they are a member from the other site. If they are, they are directed to a members area on y.com. If not, they have to provide login information on y.com. Cookies obviously don't work due to the cross domain security, but is there a way around this? I've also looked at a service for tokens, but I'm not sure exactly how that works in Classic ASP. Any ideas or suggestions?

• Bullet physics engine, how to freeze an object?

  - by Markus

  Using Bullet 2.76 I'm trying to freeze an object (rigid body) so that it instantly stops moving, but still responds to collisions. I tried setting it's activation state to DISABLE_SIMULATION, but then it's virtually nonexistent to other objects. Furthermore, if objects "collide" with it when it's disabled, strange things begin to happen (object's falling through static bodies, etc.) I suppose, temporarily converting it to a static rigid body could work, but is there an existing "native" way to achieve this on Bullet's side? Edit: Is there a way to turn off gravity for a specific object?

• Is Lightweight Code Generation (LCG) dead?

  - by Greg Beech

  In the .NET 2.0-3.5 frameworks, LCG (aka the DynamicMethod class) was a decent way to emit lightweight methods at runtime when no class structure was needed to support them. In .NET 4.0, expression trees now support statements and blocks, and as such appear to provide sufficient functionality to build just about any functionality you could require from such a method, and can be constructed in a much easier and safer way than directly emitting CIL op-codes. (This statement is borne from today's experimentation of converting some of our most complex LCG code to use expression tree building and compilation instead.) So is there any reason why one would use LCG in any new code? Is there anything it can do that expression trees cannot? Or is it now a 'dead' piece of functionality?

• Using GWT to output XML, JSON and regular HTML

  - by Artem

  Sorry, this is a very basic question, as we are just getting started with exploring GWT. We would like to know if it's easy and possible to get GWT to "output" XML, JSON and regular HTML. I would like to know this because ideally we would port parts of our backends over slowly, and it would be nice to drop in GWT in place of AJAX wherever we need it during the transition period. Places that we would like to be able to use: 1) We have a pure XML page that we return to our client (mobile) app and right now this is handled through Spring MVC with a nice template. What's the best replacement for this? 2) We have a regular AJAX page that makes async requests and expects replies in JSON. Can we easily replace this backend? 3) We have some regular webpages where we use templates to output them, and we would like to first switch them over in the simplest possible way, without converting them to the regular GWT UI framework. Thanks!

• For what purpose does java have a float primitive type?

  - by Roman

  I heard plenty times different claims about float type in java. The most popular issues typicaly regard to converting float value to double and vice versa. I read (rather long time ago and not sure that it's actual now with new JVM) that float gives much worse performance then double. And it's also not recommended to use float in scientific applications which should have certain accuracy. I also remember that when I worked with AWT and Swing I had some problems with using float or double (like using Point2D.Float or Point2D.Double). So, I see only 2 advantages of float over double: it needs only 4 bytes while double needs 8 bytes JMM garantees that assignment operation is atomic with float variables while it's not atomic with double's. Are there any other cases where float is better then double? Do you use float's in your applications? It seems to me that the only valuable reason java has float is backward compatibility.

• Anyone know of a .net library/utility that will convert a word document to an mp3 format

  - by EJB

  Anyone know of any well-supported/proven methods for converting a Microsoft word document to an MP3 or wav format such that hearing-impaired folks could "listen" to documents that I have stored in my web-based document management system? I already have the interface built such that someone can use the telephone to get the list of documents available, with the dates and titles "read" to them over the phone, but now I would like the ability to let someone actually listen to the contents of word files stored in the system. Ideally a .net library or utility that would let me convert the DOC - MP3 after each upload would be best, but one that "read" the file on demand would be OK too.

• Convert Enum to String

  - by Eric Weilnau

  Which is the preferred way to convert an Enum to a String in .NET 3.5? Enum.GetName Enum.Format toString Why should I prefer one of these over the others? Does one perform better? Justification for Accepted Answer Based on the forum post in panesofglass answer, it appears that Microsoft indirectly endorses the following method of converting an enum value to a string. Do not convert an enum value to a string using built-in enum methods. ... This will cause problems when Dotfuscating. You should not use enum.ToString(), enum.GetNames(), enum.GetName(), enum.Format() or enum.Parse() to convert an enum to a string. Instead, use a switch statement, and also internationalize the names if necessary.

• How to preview any files inside a Java application ?

  - by Studer

  I'm using a JTree to browse the content of a folder and I want that when a user click on a file, the software shows a preview of it (a screenshot of its first page). The files are mostly Office documents and PDF. I manage to do it for PDF file using a module downloaded from Sun, but I'd like to know if there is a way to do it using any software (JARs preferably) or even the built-in Windows API. I was thinking of converting the file to PDF then do a preview of this PDF but this isn't optimal. Any ideas ?

• C# Convert negative int to 11 bits

  - by Klemenko

  I need to convert numbers in interval [–1024, 1016]. I'm converting to 11 bits like that: string s = Convert.ToString(value, 2); //Convert to binary in a string int[] bits = s.PadLeft(11, '0') // Add 0's from left .Select(c => int.Parse(c.ToString())) // convert each char to int .ToArray(); // Convert IEnumerable from select to Array This works perfectly for signed integers [0, 1016]. But for negative integers I get 32 bits result. Do you have any idea how to convert negative integers to 11 bits array?

• Ruby (on Rails) && PHP - two great things that work great together???

  - by pedalpete

  I've done very little work with Ruby, and have an app I've written in PHP. I would like to add some functionality which is available in open sourced Ruby code. I could either try to translate the Ruby to PHP, or try mixing the two. Though I think the mixing part would be somewhat silly. I believe my options are to either mix ruby with php, or translate the ruby code into php. Anybody have any suggestions on this, or other ideas? I am not really interested in converting my entire app into Ruby just so I can get this feature (I saw Derek Sivers post about that which convinced me. http://www.oreillynet.com/ruby/blog/2007/09/7%5Freasons%5Fi%5Fswitched%5Fback%5Fto%5Fp%5F1.html)

• using .NET how to convert iso8859-1 encoded text files that contain Latin-1 accented characters to u

  - by Tim

  I am being sent text files saved in iso88591-1 format that contain accented characters from the Latin-1 range (as well as normal ASCII a-z etc). How to convert these files to utf-8 using C# so that the single-byte accented characters in iso8859-1 become valid utf-8 characters? I have tried to use a StreamReader with ASCIIEncoding, and then converting the ascii string to UTF-8 by instantiating an ascii encoding and a utf8 encoding and then using Encoding.Convert(ascii, utf8, ascii.GetBytes( asciiString) ) — but the accented characters are being rendered as question marks. What step am I missing?

• Oracle (Old?) Joins

  - by Grasper

  I have been porting oracle selects, and I have been running across a lot of queries like so: SELECT e.last_name, d.department_name FROM employees e, departments d WHERE e.department_id(+) = d.department_id; ...and: SELECT last_name, d.department_id FROM employees e, departments d WHERE e.department_id = d.department_id(+); Are there any guides/tutorials for converting all of the variants of the (+) syntax? What is that syntax even called (so I can scour google)? When was this standard phased out? Any info is appreciated.
