• Is it possible to shrink rt.jar with ProGuard?

  - by PatlaDJ

  Is there a procedure by which you can optimize/shrink/select/obfuscate only 'used by your app' classes/methods/fields from rt.jar provided by Sun by using some optimization software like ProGuard (or maybe other?). Then you would actually be able to minimize the download size of your application considerably and make it much more secure ? Right? Related questions: Do you know if Sun's "jigsaw project" which is waited to come out, is intended to automatically handle this particular issue? Did somebody manage yet to form an opinion about Avian java alternative? Please share it here. Thank you.

• Where's the font setting for folders in the Package Explorer?

  - by Carl Smotricz

  I'm talking about Eclipse (3.5 = Galileo), running under Kubuntu 9.10 and I have the Subversive plugin. I've been moved from Gnome-Ubuntu to Kubuntu, and one side effect was that some fonts are now just too tiny to read. File names in the explorer have a decent size, but folders are shown in a too-small font, and after having adjusted all the fonts in General|Appearance|Colors and Fonts the folders are unchanged. Maybe I'm just blind. I'd appreciate it if someone could point me to where I can adjust the font for folders in the Package Explorer

• C++ memory management of reference types

  - by Russel

  Hello, I'm still a fairly novice programmer and I have a question about c++ memory management with refence types. First of all, my understanding of reference types: A pointer is put on the stack and the actual data that the pointer points to is created and placed on the heap. Standard arrays and user defined classes are refence types. Is this correct? Second, my main question is do c and c++'s memory management mechanisms (malloc, free and new, delete) always handle this properly and free the memory that a class or array is pointing to? Does everything still work if those pointers get reassigned somehow to other objects of the same size/type on the heap? What if a class has a pointer member that points to another object? I am assuming that delete/freeing the class object doesn't free what it's member pointer points to, is that correct? Thanks all! -R

• Base64 encoding in PHP not working for '&' and '#' ?

  - by Angad

  My knowledge about base64 is pretty limited. I am using it as an alternative to string escaping in a content management system, for I had been warned about how weaknesses have been found in mysql_real_escape_string(); and quite sheepishly so, as I am aware of how it buffs text size up. PHP seems to truncate everything after an instance of # or & in the string; please help me out of this one. Also, comment on whether using base64 to maintain the 'trueness' of post content in the CMS is just plain retarded, or a wise move. Thanks for your time :)

• Right floated div within a liquid-width div. How do I get this to work?

  - by DavidR

  I have a div, within the div is a name in an <h4> tag (it's semantically correct with the layout) and a div with some values describing that <h4> value. I want the nested div to be on the right side, and the only way I can get this to work is a fixed-width container and float: right;. As you can guess, the object breaks when the value of the <h4> causes the nested div to overflow. I've tried min-width, but it ends up stretching to the maximum size of the div containing the container div.

• How to receive HTTP messages using Socket

  - by Poma

  I'm using Socket class for my web client. I can't use HttpWebRequest since it doesn't support socks proxies. So I have to parse headers and handle chunked encoding by myself. The most difficult thing is to determine length of content so I have to read it byte-by-byte. First I have to use ReadByte() to find last header ("\r\n\r\n" combination), then read chunk's size etc. But this approach has very poor performance. Can you suggest better solution? Maybe some open source examples or libraries that handle http request through sockets (not very big and complicated though, I'm a noob)

• Is there any significant benefit to reading string directly from control instead of moving it into a

  - by Kevin

  sqlInsertFrame.Parameters.AddWithValue("@UserName", txtUserName.txt); Given the code above...if I don't have any need to move the textbox data into a string variable, is it best to read the data directly from the control? In terms of performance, it would seem smartest to not create any unnecessary variables which use up memory if its not needed. Or is this a situation where its technically true but doesn't yield any real world results due to the size of the data in question. Forgive me, I know this is a very basic question.

• Flickering when repainting a JPanel inside a JScrollPAne

  - by pR0Ps

  I'm having a problem with repainting a JPanel inside a JScrollPane. Basically, I'm just trying to 'wrap' my existing EditPanel (it originally extended JPanel) into a JScrollPane. It seems that the JPanel updates too often (mass flickering). How would I stop this from happening? I tried using the setIgnoreRepaint() but it didn't seem to do anything. Will this current implementation work or would I need to create another inner class to fine-tune the JPanel I'm using to display graphics? Skeleton code: public class MyProgram extends JFrame{ public MyProgram(){ super(); add(new EditPanel()); pack(); } private class EditPanel extends JScrollPane{ private JPanel graphicsPanel; public EditPanel(){ graphicsPanel = new JPanel(); } public void paintComponent(Graphics g){ graphicsPanel.revalidate(); //update the scrollpane to current panel size repaint(); Graphics g2 = graphicsPanel.getGraphics(); g2.drawImage(imageToDraw, 0, 0, null); } } }

• Is there a way to combine streaming data retrieval with hibernate?

  - by Steve B.

  For the purposes of handling very large collections (and by very large I just mean "likely to throw OutOfMemory exception"), it seems problematic to use Hibernate because normally collection retrieval is done in a block, i.e. List values=session.createQuery("from X").list(), where you monolithically grab all N-million values and then process them. What I'd prefer to do is to retrieve the values as an iterator so that I grab 1000 or so (or whatever's a reasonable page size) at a time. Apart from writing my own iteration (which seems like it's likely to be re-inventing the wheel) is there a hibernate-native way to handle this?

• Restoring using SyncBack without profiles

  - by Thomas Matthews

  I backed up my internal hard drive (C:) using SyncBack onto an external (USB) hard drive with maximum compression. I then performed a clean install of Windows Vista onto the computer. I forgot to copy the SyncBack logs before the clean install. And now when ever I try to restore a directory, the RAR/ZIP files are copied to the system hard drive instead of extracting their contents to the hard drive. Also, SyncBack is not traversing the folders during the Restore process. How can I tell SyncBack to expand the compressed files? I am running the freeware version of SyncBack. I have to create new log files (unless SyncBack put them somewhere on the external drive). My alternative is to write a program that traverses the folders on the external drive and extracts files from the RAR/ZIP files. I am using Windows Vista, Service Pack 2, and the data size prior to backup was about 200 GB. (The backup process took over 72 hours due to "hiccups").

• Can Somebody Explain this java code

  - by dubbeat

  Hi, I'm just starting out on android and my java is verry rusty. I can't remember ever seeing a function nested in another function like this before. Could somebody explain to me exactly what final does and explain why you would nest a function in another like this? private final Handler handler = new Handler() { @Override public void handleMessage(final Message msg) { Log.v(Constants.LOGTAG, " " + ReviewList.CLASSTAG + " worker thread done, setup ReviewAdapter"); progressDialog.dismiss(); if ((reviews == null) || (reviews.size() == 0)) { empty.setText("No Data"); } else { reviewAdapter = new ReviewAdapter(ReviewList.this, reviews); setListAdapter(reviewAdapter); } } };

• VBScript: how to set values from recordset to string

  - by phill

  This is probably a beginner question, but how do you set a recordset to a string variable? Here is my code: Function getOffice (strname, uname) strEmail = uname WScript.Echo "email: " & strEmail Dim objRoot : Set objRoot = GetObject("LDAP://RootDSE") Dim objDomain : Set objDomain = GetObject("LDAP://" & objRoot.Get("defaultNamingContext")) Dim cn : Set cn = CreateObject("ADODB.Connection") Dim cmd : Set cmd = CreateObject("ADODB.Command") cn.Provider = "ADsDSOObject" cn.Open "Active Directory Provider" Set cmd.ActiveConnection = cn cmd.CommandText = "SELECT physicalDeliveryOfficeName FROM '" & objDomain.ADsPath & "' WHERE mail='" & strEmail & "'" cmd.Properties("Page Size") = 1 cmd.Properties("Timeout") = 300 cmd.Properties("Searchscope") = ADS_SCOPE_SUBTREE Dim objRS : Set objRS = cmd.Execute WScript.Echo objRS.Fields(0) Set cmd = Nothing Set cn = Nothing Set objDomain = Nothing Set objRoot = Nothing Dim arStore Set getOffice = objRS.Fields(0) Set objRS = Nothing End function When I try to run the function, it throws an error "vbscript runtime error: Type mismatch" I presume this means it can't set the string variable with a recordset value. How do I fix this problem?

• How to change ScrollView's position after touch?

  - by Matt

  I'm trying to make a ScrollView with a list of numbers in it that the user can select from. After the user touches and scrolls, after the finger is lifted I want the scroll to "snap" to the item in the middle of the ScrollView and give me the output. My ScrollView contains a vertical linear layout with TextView objects in it. The ScrollView's vertical size is about 60sp. I think this would involve the ScrollView.onTouch with a ACTION_UP, but I don't know how to use it. Also, is there a way to get an item's index or value based on a position in the list? Thanks!

• Which is more efficient/faster when calling a cached image?

  - by andufo

  Hi, i made an image resizer in php. When an image is resized, it caches a new jpg file with the new dimensions. Next time you call the exact img.php?file=hello.jpg&size=400 it checks if the new jpg has already been created. If it has NOT been created yet, it creates the file and then prints the output (cool). If it ALREADY exists, no new file needs to be generated and instead, it just calls the already cached file. My question is regarding the second scenario. Which of these is faster? redirecting: header('Location: cache/hello_400.jpg');die(); grabbing data and printing the cached file: $data = file_get_contents('cache/hello_400.jpg'); header('Content-type: '.$mime); header('Content-Length: '.strlen($data)); echo $data; Any other ways to improve this?

• Reading in 4 bytes at a time

  - by alphomega

  I have a big file full of integers that I'm loading in. I've just started using C++, and I'm trying out the filestream stuff. From everything I've read, it appears I can only read in bytes, So I've had to set up a char array, and then cast it as a int pointer. Is there a way I can read in 4 bytes at a time, and eliminate the need for the char array? const int HRSIZE = 129951336; //The size of the table char bhr[HRSIZE]; //The table int *dwhr; int main() { ifstream fstr; /* load the handranks.dat file */ std::cout << "Loading table.dat...\n"; fstr.open("table.dat"); fstr.read(bhr, HRSIZE); fstr.close(); dwhr = (int *) bhr; }

• Fast image coordinate lookup in Numpy

  - by victor

  I've got a big numpy array full of coordinates (about 400): [[102, 234], [304, 104], .... ] And a numpy 2d array my_map of size 800x800. What's the fastest way to look up the coordinates given in that array? I tried things like paletting as described in this post: http://opencvpython.blogspot.com/2012/06/fast-array-manipulation-in-numpy.html but couldn't get it to work. I was also thinking about turning each coordinate into a linear index of the map and then piping it straight into my_map like so: my_map[linearized_coords] but I couldn't get vectorize to properly translate the coordinates into a linear fashion. Any ideas?

• Extract object (*.o) files from an iPhone static library

  - by Brett

  I have a set of iPhone static libraries (a *.a file) in which I only call a few of the classes from. I have used AR in the past (with linux libraries) to extract the object files from the static library, remove the unwanted object files and rearchive. However, when I try this with an iPhone compliled static library, I get the following error: ar: CustomiPhoneLib.a is a fat file (use libtool(1) or lipo(1) and ar(1) on it) ar: CustomiPhoneLib.a: Inappropriate file type or format Does anyone know how to extract the object files from an iphone compiled static library? Doing thie could potentially reduce the final file size.

• Migrating from mssql to firebird: pro and cons

  - by user193655

  i am considering the migration for 3 reasons: 1) SQLSERVER installation is a nightmar, expecially for 1-user software. Software installs in 10 seconds, SQLServer in 1 hour. Firebird installation is much easier. 2) SQLSERVER runs on windows server only 3) My customers have all the express edition 4) i am not using any advanced feature, I am now starting using filestream, but the main reason for this is that Express eidtion has 4/10GB db size limit So these are all Pros of moving to Firebird. Which are the cons? I can also plan to support both platiforms, but this will backfire I fear.

• Samsung Galaxy Tab 1 layout problems

  - by William Rae

  I'm having trouble running my app on the Galaxy tab original 7". It appears to make everything 1.5 times bigger, i.e. if I specify 40dip for a textSize in my layout, it will display as 60 dip when I run it on the tablet. I tried messing around with the display metrics and changing the density and densityDpi to 1. (When I run a toString of the display metrics in the Galaxy tab 2, they are both 1, whereas the Galaxy tab 1 has values of 1.5) The app runs very well on every phone I've tested it on, and on the Galaxy tab 2, so I can't figure out what the problem is. I even tried creating a dummy app with just a textView with a size of 40dip, and it still converted it to 60. Any ideas? Thanks.

• Why are all my masked views unmasked in my view snapshot?

  - by mystify

  I'm taking a snapshot of an view. This view has got some subviews which have layer masks applied to them. For some reason, those masks take no effect in the snapshot and the masked parts are completely visible. UIGraphicsBeginImageContext(theView.frame.size); [theView.layer renderInContext:UIGraphicsGetCurrentContext()]; UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); I assume this is a bug in the framework. But maybe it's not? Did I do anything wrong here?

• Using C# to iterate form fields with same name

  - by itsatrp

  I have a section of a form that I need to handle differently from the rest of form results. In the section that needs special handling I need to iterate over 3 form fields that have the same name. They have to have the same name, I can't change it. The section of the form I am referring to looks something like this: <td><input name="Color" size="20" value="" type="text"></td> Using C# I try something like this: I try to handle it like this: int i; for (i = 1; i <= Request.Form["Color"][i]; i++) { colorName.Text += Request.Form["Color"]; } Which leads to the following exception: System.NullReferenceException: Object reference not set to an instance of an object. How should I be handling form fields with the same name?
