  • What is the Best JQuery WYSIWYM Textile Editor?

    - by viatropos
    I need to use a Textile (preferably instead of Markdown), and am looking for a nice WYSIWYM (not WYSIWYG, because of this) JQuery editor. I've seen these: WMD - Markdown, Stack Overflow uses it MarkItUp - Textile support but I don't know if it's WYSIWYM WYMEditor Which one supports both good HTML output and Textile?

  • Delphi 6 - Bugs disappear when I compile multiple times.

    - by Daisetsu
    My Delphi installation has been going downhill for the past few months. It seems though that every so often when I build a release it has strange errors in it which are resolved if I build, then compile, then build, compile, etc. I've talked to another developer who thinks that this is a compiler error. This sort of degrading performance over time has happened on other computers to us too. What does stack overflow think could be the problem.

  • Why / When / How is this Android serviceBinder resetting to null?

    - by GaZ
    I've written a ListActivity for Android 2.1 which is used to display a list of event categories. As the user selects a category, the program calls a web service to retrieve a list of sub-events. For example, a top level event might be "soccer" and when the user selects this the web service would return various soccer associations (e.g. "english", "french", "german", etc.) and display them in a new list. The following code seems to work occasionally, however sometimes the call to the service (in EventsListTask) fails because the serviceBinder is null. How/Why does this happen? public class EventListsActivity extends ListActivity { private static final String EVENT_ID = "EventId"; private List<ListItem> eventList; private ArrayAdapter<ListItem> listItemArrayAdapter; private static final int LOADING_DIALOG = 1; private EventsListTask eventsListTask = null; private BFService serviceBinder; private ServiceConnection mConnection = new ServiceConnection() { public void onServiceConnected(ComponentName componentName, IBinder iBinder) { Log.i("EventListsActivity", "service connected"); serviceBinder = ((BFService.BFBinder)iBinder).getService(); } public void onServiceDisconnected(ComponentName componentName) { Log.i("EventListsActivity", "service disconnected"); serviceBinder = null; } }; @Override public void onCreate(Bundle savedInstanceState) { Log.i("EventListsActivity", "onCreate"); super.onCreate(savedInstanceState); setContentView(R.layout.list); eventList = new ArrayList<ListItem>(); listItemArrayAdapter = new ArrayAdapter<ListItem>(this, R.layout.row, eventList); setListAdapter(listItemArrayAdapter); Intent bindIntent = new Intent(this, BFService.class); bindService(bindIntent, mConnection, Context.BIND_AUTO_CREATE); int eventId = getIntent().getIntExtra(EVENT_ID, -1); if (eventsListTask == null || eventsListTask.getStatus() == AsyncTask.Status.FINISHED) { eventsListTask = new EventsListTask(); eventsListTask.execute(eventId); } } @Override protected void onDestroy() { Log.i("EventListsActivity", "destroyed"); super.onDestroy(); unbindService(mConnection); } @Override protected void onListItemClick(ListView listView, View view, int position, long id) { super.onListItemClick(listView, view, position, id); ListItem selectedItem = (ListItem) listView.getAdapter().getItem(position); Intent intent; if (selectedItem.getMarketType() != null) { intent = new Intent(this, MarketActivity.class); intent.putExtra(EVENT_ID, selectedItem.getId()); startActivityIfNeeded(intent, -1); } else if (selectedItem.getId() != -1) { intent = new Intent(this, EventListsActivity.class); intent.putExtra(EVENT_ID, selectedItem.getId()); startActivityIfNeeded(intent, -1); } else { Log.e("EventListsActivity", "unexpected item selected!"); } } @Override protected Dialog onCreateDialog(int id) { switch (id) { case (LOADING_DIALOG) : AlertDialog.Builder loadingDialog = new AlertDialog.Builder(this); loadingDialog.setTitle("Please Wait..."); loadingDialog.setMessage("Communicating with remote service."); return loadingDialog.create(); } return null; } private class EventsListTask extends AsyncTask<Integer, Void, LoginStatusEnum> { @Override protected void onPreExecute() { showDialog(LOADING_DIALOG); } @Override protected void onPostExecute(LoginStatusEnum loginStatusEnum) { dismissDialog(LOADING_DIALOG); if (loginStatusEnum != null) { switch (loginStatusEnum) { case OK: for (ListItem item : eventList) { listItemArrayAdapter.add(item); } listItemArrayAdapter.notifyDataSetChanged(); break; } } } @Override protected LoginStatusEnum doInBackground(Integer... params) { LoginStatusEnum result = LoginStatusEnum.OK; Integer eventId = params[0]; if (serviceBinder != null) { try { if (eventId == null || eventId == -1) { eventList = serviceBinder.getActiveEventTypes(); } else { eventList = serviceBinder.getEvents(eventId); } } catch (WebServiceException wse) { result = LoginStatusEnum.valueOf(wse.getMessage()); } } else { Log.e("EventListsActivity", "serviceBinder is null!"); } return result; } } } EDIT: The serviceBinder appears to be set to null when I reach the bottom of a list, when I change the target intent to go to a different activity: intent = new Intent(this, MarketActivity.class); intent.putExtra(EVENT_ID, selectedItem.getId()); startActivity(intent); This new activity also uses the same background service (binds in the same way, etc.). Is there anything I need to watch out for when doing this? Am I calling the target intent incorrectly? EDIT2: Here's the output from LogCat when I start the activity which calls the service (this time the service failed straight away!): 04-02 07:02:49.147: INFO/ActivityManager(61): Starting activity: Intent { cmp=net.foobar.activity/.EventListsActivity } 04-02 07:02:49.257: INFO/EventListsActivity(353): onCreate 04-02 07:02:49.426: INFO/EventListsActivity(353): service connected 04-02 07:02:49.437: ERROR/EventListsActivity(353): serviceBinder is null!

  • How to disable scrollbars with JavaScript?

    - by Flupkear
    I need to lock the browser scrollbars when I show a div that represent a modal window in Internet Explorer 7 only. Googling I found that I can use document.body.style.overflow='hidden' but this doesn't work for IE7. I also tried with document.body.scroll="no" which works but only after I mouse over the scrollbar :-S Does anybody knows a better aproach? Thansks

  • Easiest way to implement RSS reader on Google Android?

    - by user291888
    Hi guys, This is my first time on stack overflow, so I apologize if this question has been asked before, but is there an easy way to implement an RSS reader on the Google Android (API 1.5)? I'm searched far and wide with the code sources I know of, and I've only found one implementation which takes 6 different classes and doesn't seem to compile on the current Android SDK's. If I end up having to write my own, I'll be sure to post it here later on. Thanks a lot.

  • GCC, -O2, and bitfields - is this a bug or a feature?

    - by Rooke
    Today I discovered alarming behavior when experimenting with bit fields. For the sake of discussion and simplicity, here's an example program: #include <stdio.h> struct Node { int a:16 __attribute__ ((packed)); int b:16 __attribute__ ((packed)); unsigned int c:27 __attribute__ ((packed)); unsigned int d:3 __attribute__ ((packed)); unsigned int e:2 __attribute__ ((packed)); }; int main (int argc, char *argv[]) { Node n; n.a = 12345; n.b = -23456; n.c = 0x7ffffff; n.d = 0x7; n.e = 0x3; printf("3-bit field cast to int: %d\n",(int)n.d); n.d++; printf("3-bit field cast to int: %d\n",(int)n.d); } The program is purposely causing the 3-bit bit-field to overflow. Here's the (correct) output when compiled using "g++ -O0": 3-bit field cast to int: 7 3-bit field cast to int: 0 Here's the output when compiled using "g++ -O2" (and -O3): 3-bit field cast to int: 7 3-bit field cast to int: 8 Checking the assembly of the latter example, I found this: movl $7, %esi movl $.LC1, %edi xorl %eax, %eax call printf movl $8, %esi movl $.LC1, %edi xorl %eax, %eax call printf xorl %eax, %eax addq $8, %rsp The optimizations have just inserted "8", assuming 7+1=8 when in fact the number overflows and is zero. Fortunately the code I care about doesn't overflow as far as I know, but this situation scares me - is this a known bug, a feature, or is this expected behavior? When can I expect gcc to be right about this? Edit (re: signed/unsigned) : It's being treated as unsigned because it's declared as unsigned. Declaring it as int you get the output (with O0): 3-bit field cast to int: -1 3-bit field cast to int: 0 An even funnier thing happens with -O2 in this case: 3-bit field cast to int: 7 3-bit field cast to int: 8 I admit that attribute is a fishy thing to use; in this case it's a difference in optimization settings I'm concerned about.

  • Is there a Markdown editor for Dojo

    - by Emilien
    Is there a good Markdown editor for Dojo? I have seen Control.TextArea (based on Prototype) and Stack Overflow's reverse-engineered version of WMD (seems to rely on jQuery) but I'd rather use a Dojo-based tool, as my site already uses this framework. Does such a tool exist? Googling for dojo markdown editor doesn't seem to return any useful results, apart from a Google Summer of Code 2008 student blogging that he's working on it...

  • How to style a code block to make all the colours look pretty like my IDE and here in stackoverflow?

    - by BritishDeveloper
    When putting code samples in my blog I would like the code to have all the appropriate colours. How can I do that? Basically if I write: foreach (ListItem item in items) { item.Text = "something"; } I want it to appear in the correct colours like it does in my Visual Studio or here at stack*overflow*. I'm bored of styling the colours of each key word manually. Is there a pre-existing javascript library I can use?

  • Bitwise Operations -- Arithmetic Operations..

    - by RBA
    Hi, Can you please explain the below lines, with some good examples. A left arithmetic shift by n is equivalent to multiplying by 2n (provided the value does not overflow), while a right arithmetic shift by n of a two's complement value is equivalent to dividing by 2n(2 to the power n) and rounding toward negative infinity. If the binary number is treated as ones' complement, then the same right-shift operation results in division by 2n and rounding toward zero. Thankx..

  • Subroutine & GoTo design

    - by sub
    I have a strange question concerning subroutines: As I'm creating a minimal language and I don't want to add high-level loops like while or for I was planning on just adding gotos to keep it Turing-Complete. Now I thought, eww - gotos - I wouldn't want to program in that language if I had to use gotos so often. So I thought about adding subroutines instead. I see the difference as the following: gotos Go to (captain obvious) a previously defined point and continue executing the program from there. Leads to hardly understandable and buggy code, I think that's a fact. subroutines Similiar: You define their starting point somewhere, as you call them the program jumps there - but the subroutine can go back to the point it was called from with return. Okay. Why didn't I just add the more function-like, nice looking subroutines? Because: In order to make return work if I call subroutines from within subroutines from within other subroutines, I'd have to use a stack containing the point where the currently running subroutine came from at top. That would then mean that I would, if I create loops using the subroutines, end up with an extremely memory-eating, overflowing stack with return locations. Not good. Don't think of my subroutines as functions. They are just gotos that return to the point they were called from, they don't actually give back values like the return x; statement in nearly all today's languages. Now to my actual questions: How can I solve the above problem with the stack overflow on loops with subroutines? Do I have to add a separate goto language construct without the return option? Assembler doesn't have loops but as I have seen myJumpPoint:, jnz, jz, retn. That means to me that there must also be a stack containing all the return locations. Am I right with that? What about long running loops then? Don't they overflow the stack/eat memory then? Am I getting the retn symbol in assembler totally wrong? If yes, please explain it to me.

  • How to scroll text in Python/Curses subwindow?

    - by lecodesportif
    In my Python script which uses Curses, I have a subwin to which some text is assigned. Because the text length may be longer than the window size, the text should be scrollable. It doesn't seem that there is any CSS-"overflow" like attribute for Curses windows. The Python/Curses docs are also rather cryptic on this aspect. Does anybody here have an idea how I can code a scrollable Curses subwindow using Python and actually scroll through it? \edit: more precise question

  • Simple 3x3 matrix inverse code (C++)

    - by batty
    What's the easiest way to compute a 3x3 matrix inverse? I'm just looking for a short code snippet that'll do the trick for non-singular matrices, possibly using Cramer's rule. It doesn't need to be highly optimized. I'd prefer simplicity over speed. I'd rather not link in additional libraries. Primarily I was hoping to have this on Stack Overflow so that I wouldn't have to hunt around for it or rewrite from scratch again next time.

    There is a lot of information on how to find the next power of 2 of a given value (see refs) but I cannot find any to get the previous power of two. The only way I find so far is to keep a table with all power of two up to 2^64 and make a simple lookup. Acius' Snippets gamedev Bit Twiddling Hacks Stack Overflow

  • 3d symmetry search algorithm

    - by aaa
    this may be more appropriate for math overflow, but nevertheless: Given 3d structure (for example molecule), what is a good approach/algorithm to find symmetry (rotational/reflection/inversion/etc.)? I came up with brute force naive algorithm, but it seems there should be better approach. I am not so much interested in genetic algorithms as I would like best symmetry rather then almost the best symmetry link to website/paper would be great. thanks
