• Can a Java HashMap's size() be out of sync with its actual entries' size ?

  - by trix

  I have a Java HashMap called statusCountMap. Calling size() results in 30. But if I count the entries manually, it's 31 This is in one of my TestNG unit tests. These results below are from Eclipse's Display window (type code - highlight - hit Display Result of Evaluating Selected Text). statusCountMap.size() (int) 30 statusCountMap.keySet().size() (int) 30 statusCountMap.values().size() (int) 30 statusCountMap (java.util.HashMap) {40534-INACTIVE=2, 40526-INACTIVE=1, 40528-INACTIVE=1, 40492-INACTIVE=3, 40492-TOTAL=4, 40513-TOTAL=6, 40532-DRAFT=4, 40524-TOTAL=7, 40526-DRAFT=2, 40528-ACTIVE=1, 40524-DRAFT=2, 40515-ACTIVE=1, 40513-DRAFT=4, 40534-DRAFT=1, 40514-TOTAL=3, 40529-DRAFT=4, 40515-TOTAL=3, 40492-ACTIVE=1, 40528-TOTAL=4, 40514-DRAFT=2, 40526-TOTAL=3, 40524-INACTIVE=2, 40515-DRAFT=2, 40514-ACTIVE=1, 40534-TOTAL=3, 40513-ACTIVE=2, 40528-DRAFT=2, 40532-TOTAL=4, 40524-ACTIVE=3, 40529-ACTIVE=1, 40529-TOTAL=5} statusCountMap.entrySet().size() (int) 30 What gives ? Anyone has experienced this ? I'm pretty sure statusCountMap is not being modified at this point. There are 2 methods (lets call them methodA and methodB) that modify statusCountMap concurrently, by repeatedly calling incrementCountInMap. private void incrementCountInMap(Map map, Long id, String qualifier) { String key = id + "-" + qualifier; if (map.get(key) == null) { map.put(key, 0); } synchronized (map) { map.put(key, map.get(key).intValue() + 1); } } methodD is where I'm getting the issue. methodD has a TestNG @dependsOnMethods = { "methodA", "methodB" } so when methodD is executing, statusCountMap is pretty much static already. I'm mentioning this because it might be a bug in TestNG. I'm using Sun JDK 1.6.0_24. TestNG is testng-5.9-jdk15.jar Hmmm ... after rereading my post, could it be because of concurrent execution of outside-of-synchronized-block map.get(key) == null & map.put(key,0) that's causing this issue ?

• Problem on creating font using a custom ant task, which extends LWUIT's FontTask.

  - by Smithy

  Hi. I am new to LWUIT and j2me, and I am building a j2me application for showing Japanese text vertically. The phonetic symbol part of the text should be shown in relatively small font size (about half the size of the text), small Kanas need to be shown as normal ones, and some 'vertical only' characters need to be put into the Private Use Area, etc. I tried to build this font into a bitmap font using the FontTask ant task LWUIT provided, but found that it does support the customizations mentioned above. So I decided to write my own task and add those. Below is what I have achieved: 1 An ant task extending the LWUITTask task to support a new nested element <verticalfont>. public class VerticalFontBuildTask extends LWUITTask { public void addVerticalfont(VerticalFontTask anVerticalFont) { super.addFont(anVerticalFont); } } 2 The VerticalFontTask task, which extends the original FontTask. Instead of inserting a EditorFont object, it inserts a VerticalEditorFont object(derived from EditorFont) into the resource. public class VerticalFontTask extends FontTask { // some constants are omitted public VerticalFontTask() { StringBuilder sb = new StringBuilder(); sb.append(UPPER_ALPHABET); sb.append(UPPER_ALPHABET.toLowerCase()); sb.append(HALFWIDTH); sb.append(HIRAGANA); sb.append(HIRAGANA_SMALL); sb.append(KATAKANA); sb.append(KATAKANA_SMALL); sb.append(WIDE); this.setCharset(sb.toString()); } @Override public void addToResources(EditableResources e) { log("Putting rigged font into resource..."); super.addToResources(e); //antialias settings Object aa = this.isAntiAliasing() ? RenderingHints.VALUE_TEXT_ANTIALIAS_ON :RenderingHints.VALUE_TEXT_ANTIALIAS_OFF; VerticalEditorFont ft = new VerticalEditorFont( Font.createSystemFont( this.systemFace, this.systemStyle, this.systemSize), null, getLogicalName(), isCreateBitmap(), aa, getCharset()); e.setFont(getName(), ft); } VerticalEditorFont is just a bunch of methods logging to output and call the super. I am still trying to figure out how to extend it. But things are not going well: none of the methods on the VerticalEditorFont object get called when executing this task. My questions are: 1 where did I do wrong? 2 I want to embed a truetype font to support larger screens. I only need a small part of the font inside my application and I don't want it to carry a font resource weighing 1~2MB. Is there a way to extract only the characters needed and pack them into LWUIT?

• What font do you use for your code editor?

  - by Harmen

  For a long time I used Courier New as default font for my code editor, until I got more into typography and found this new fixed-width font called Triskweline: The font is beautiful, but unfortunately it works only at size 10pt. This made me wonder: what (custom) font do you use for your code editor?

• Apache2 mod_proxy and post-multipart size

  - by Pietro

  Hi, I have Apache2 configured to proxy all traffic directed to a specific virtual host to a local tomcat instance. All is good and fine but for multipart posts larger than ~100kb. Such posts fail on the tomcat end with an exception like SocketTimeoutException. If I connect directly to Tomcat (which listens on a port != 80) then all posts are handled just fine. The Apache virtual host config goes like this: NameVirtualHost * SetOutputFilter DEFLATE <VirtualHost *> ServerName foo.bar.com ErrorLog c:/wamp/logs/foo_error.log CustomLog c:/wamp/logs/foo_access.log combined ProxyTimeout 60 ProxyPass / http://localhost:10080/foo/ ProxyPassReverse / http://localhost:10080/foo/ ProxyPassReverseCookieDomain localhost bar.com ProxyPassReverseCookiePath /foo / </VirtualHost> I tried browsing the Apache2 and mod_proxy docs but found nothing useful. Any idea why Apache2 refuses to proxy requests bigger than X bytes ? Thanks!

• Exchange 2003 automated mailbox size report

  - by Morris

  I have a question if I may. I have been looking for a while for something that can report user mailbox sizes and percentage used against their quota or something that can warn me when a mailbox is getting close to the quota. I know the user receives a warning but how can I send that same warning a centralized mailbox so we can be pro-active in our support. Either a script or an application that can do this will be helpful. Unfortunately my scripting skills are useless for something this complex. Any ideas of what can be used will be appreciated.

• VMware Fusion disk size

  - by churnd

  I have a Windows XP x64 install in VMware Fusion. The amount of space that the VM reports as used (C:) is ~20GB. However, the amount of space the VM is taking up on my disk is 30GB. Why the inconsistency? I do not have autoprotect enabled, nor do I have any snapshots I'm aware of. I have defragmented the drive and used Drive Cleanup from the VMware settings.

• Minimum size of a boot partition on debian

  - by zebonaut

  I'm setting up an old box with Debian. First etch (4.0), because this is the last version that still had boot floppies, then the box is to be upgraded to lenny (5.0) and squeeze (6.0). Therefore, I will end up having a a couple of different kernel versions in the boot partition. If I don't want to be wasteful and if I end up needing a separate boot partition, how large should it be? I've used 10 MB long ago, but that was woody, and only one kernel in the boot partition, and this seems to be too small for what I want to do now.

In the first post, JMS Step 1 - How to Create a Simple JMS Queue in Weblogic Server 11g we looked at how to create a JMS queue and its dependent objects in WebLogic Server. In the previous post, JMS Step 2 - Using the QueueSend.java Sample Program to Send a Message to a JMS Queue I showed how to write a message to that JMS queue using the QueueSend.java sample program. In this article, we will use a similar sample, the QueueReceive.java program to read the message from that queue. Please review the previous posts if you have not already done so, as they contain prerequisites for executing the sample in this article. 1. Source code The following java code will be used to read the message(s) from the JMS queue. As with the previous example, it is based on a sample program shipped with the WebLogic Server installation. The sample is not installed by default, but needs to be installed manually using the WebLogic Server Custom Installation option, together with many, other useful samples. You can either copy-paste the following code into your editor, or install all the samples. The knowledge base article in My Oracle Support: How To Install WebLogic Server and JMS Samples in WLS 10.3.x (Doc ID 1499719.1) describes how to install the samples.

How to Use This Class 2.1 From the file system on Linux This section describes how to use the class from the file system of a WebLogic Server installation. Log in to a machine with a WebLogic Server installation and create a directory to contain the source and code matching the package name, e.g. span$HOME/examples/jms/queue. Copy the above QueueReceive.java file to this directory. Set the CLASSPATH and environment to match the WebLogic server environment. Go to $MIDDLEWARE_HOME/user_projects/domains/base_domain/bin  and execute . ./setDomainEnv.sh Collect the following information required to run the script: The JNDI name of the JMS queue to use In the WebLogic server console > Services > Messaging > JMS Modules > Module name, (e.g. TestJMSModule) > JMS queue name, (e.g. TestJMSQueue) select the queue and note its JNDI name, e.g. jms/TestJMSQueue The JNDI name of the connection factory to use to connect to the queue Follow the same path as above to get the connection factory for the above queue, e.g. TestConnectionFactory and its JNDI name e.g. jms/TestConnectionFactory The URL and port of the WebLogic server running the above queue Check the JMS server for the above queue and the managed server it is targeted to, for example soa_server1. Now find the port this managed server is listening on, by looking at its entry under Environment > Servers in the WLS console, e.g. 8001 The URL for the server to be passed to the QueueReceive program will therefore be t3://host.domain:8001 e.g. t3://jbevans-lx.de.oracle.com:8001 Edit Queue Receive .java and enter the above queue name and connection factory respectively under ... public final static String JMS_FACTORY="jms/TestConnectionFactory"; ... public final static String QUEUE="jms/TestJMSQueue"; ... Compile Queue Receive .java using javac Queue Receive .java Go to the source’s top-level directory and execute it using java examples.jms.queue.Queue Receive   t3://jbevans-lx.de.oracle.com:8001 This will print a message that it is ready to receive messages or to send a “quit” message to end. The program will read all messages in the queue and print them to the standard output until it receives a message with the payload “quit”. 2.2 From JDeveloper The steps from JDeveloper are the same as those used for the previous program QueueSend.java, which is used to send a message to the queue. So we won't repeat them here. Please see the previous blog post at JMS Step 2 - Using the QueueSend.java Sample Program to Send a Message to a JMS Queue and apply the same steps in that example to the QueueReceive.java program. This concludes the example. In the following post we will create a BPEL process which writes a message based on an XML schema to the queue.

• Embedding/deploying custom font in .NET app

  - by Swingline Rage

  Is there an official way to distribute (deploy) a specific font with a .NET application? We have a (public domain) "LED font" that prints numbers with the retro LED instrumentface look. This is a standard True Type or Open Type font like any other except it looks funky. Obviously for that to work, this font needs to be on the user's machine. But we'd prefer to not force the user to "install our special font into your font folder". We'd prefer to either load a Font object directly from the TTF, or programatically install the font so it's available. How do applications handle this sort of things? Eg, I notice Adobe XYZ installs various fonts on the system without user intervention. That's what we'd like to do. EDIT: okay, ideally, we'd prefer not to install the font directly. We don't want our nifty themed LED font showing up in the user's font dropdown in MS Word. We'd prefer to use this font, but restrict its use or appearance to our app. Any way to do this? Thanks!

• How does font rendering actually work?

  - by Andrea

  I realize that I know essentially nothing about the way fonts get rendered in my computer. From what I can observe, font rendering is generally made in a consistent way throughout the system. For instance, the subpixel font hinting settings that I configure in my DE control panel have influence on text which appears on window borders, in my browser, in my text editor and so on. (I should observe that some Java applications show a noticeable difference, so I guess they are using a different font rendering mechanism). What I get from the above is that probably all applications that need font rendering make use of some OS (or DE)-wide library. On the other hand, browsers usually manage their own rendering through a rendering engine, that takes care of positioning various items - including text - according to specific flow rules. I am not sure how these two facts are compatible. I would assume that the browser would have to ask the OS to draw a glyph at a given position, but how can it manage the flow of text without knowing beforehand how much space the glyph will take? Are there separate calls to determine the glyph sizes, so that the browser can manage the flow as if characters were little boxes that are later filled in by the OS? (Although this does not take care of kerning). Or is the OS responsible for drawing a whole text area, including text flow? Does the OS return the rendered glyph as a bitmap and leaves it to the application to draw that on the screen?

• NPTL Default Stack Size Problem

  - by eyazici

  Hello, I am developing a multithread modular application using C programming language and NPTL 2.6. For each plugin, a POSIX thread is created. The problem is each thread has its own stack area, since default stack size depends on user's choice, this may results in huge memory consumption in some cases. To prevent unnecessary memory usage I used something similar to this to change stack size before creating each thread: pthread_attr_t attr; pthread_attr_init (&attr); pthread_attr_getstacksize(&attr, &st1); if(pthread_attr_setstacksize (&attr, MODULE_THREAD_SIZE) != 0) perror("Stack ERR"); pthread_attr_getstacksize(&attr, &st2); printf("OLD:%d, NEW:%d - MIN: %d\n", st1, st2, PTHREAD_STACK_MIN); pthread_attr_setdetachstate(&attr, PTHREAD_CREATE_DETACHED); /* "this" is static data structure that stores plugin related data */ pthread_create(&this->runner, &attr, (void *)(void *)this->run, NULL); EDIT I: pthread_create() section added. This did not work work as I expected, the stack size reported by pthread_attr_getstacksize() is changed but total memory usage of the application (from ps/top/pmap output) did not changed: OLD:10485760, NEW:65536 - MIN: 16384 When I use ulimit -s MY_STACK_SIZE_LIMIT before starting application I achieve the expected result. My questions are: 1-) Is there any portable(between UNIX variants) way to change (default)thread stack size after starting application(before creating thread of course)? 2-) Is it possible to use same stack area for every thread? 3-) Is it possible completely disable stack for threads without much pain?

• Is it possible to create a Mac OS specific CSS to fix font difference ?

  - by Gabriel

  I'm working on a project with a designer and he insisted on using some specific font for titles and various elements in the page. So we're using a font kit to embed with @font-face. It's working perfectly on PC (Firefox, IE 7 and 8, Chrome, Safari) but on Mac OS (Safari and Firefox) the fonts are not vertically aligned the same way. After looking on the Web, I didn't find any solution for this except "there always been differences between browsers and platforms, live with it". I know that fonts are never rendered exactly the same across platforms, but this time it's not something like the font looks more bold or something like that. The font looks as if it's baseline is completely different between Windows and Mac OS X. On Mac OS, the font, at a size of 16px is 3px higher than on PC. So I'm looking for a backup solution : is there a way to create a CSS specifically for Mac OS users? I do not want to target only Safari because Safari PC is ok, and Firefox Mac is not ok. Or if you have a solution to fix the baseline difference that does not require a specific CSS file, I'd be happy to hear it. Thanks!

I get nothing reguardless of what parameters I put for Draw(). class Font { public: Font() { if (FT_Init_FreeType(&ftLibrary)) { printf("Could not initialize FreeType library\n"); return; } glGenBuffers(1,&iVerts); } bool Load(std::string sFont, unsigned int Size = 12.0f) { if (FT_New_Face(ftLibrary,sFont.c_str(),0,&ftFace)) { printf("Could not open font: %s\n",sFont.c_str()); return true; } iSize = Size; FT_Set_Pixel_Sizes(ftFace,0,(int)iSize); FT_GlyphSlot gGlyph = ftFace->glyph; //Generating the texture atlas. //Rather than some amazing rectangular packing method, I'm just going //to have one long strip of letters with the height being that of the font size. int width = 0; int height = 0; for (int i = 32; i < 128; i++) { if (FT_Load_Char(ftFace,i,FT_LOAD_RENDER)) { printf("Error rendering letter %c for font %s.\n",i,sFont.c_str()); } width += gGlyph->bitmap.width; height += std::max(height,gGlyph->bitmap.rows); } //Generate the openGL texture glActiveTexture(GL_TEXTURE0); //if I texture exists then delete it. iTexture ? glDeleteBuffers(1,&iTexture):0; glGenTextures(1,&iTexture); glBindTexture(GL_TEXTURE_2D,iTexture); glPixelStorei(GL_UNPACK_ALIGNMENT,1); glTexImage2D(GL_TEXTURE_2D,0,GL_ALPHA,width,height,0,GL_ALPHA,GL_UNSIGNED_BYTE,0); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); //load the glyphs and set the glyph data int x = 0; for (int i = 32; i < 128; i++) { if (FT_Load_Char(ftFace,i,FT_LOAD_RENDER)) { //if it cant load the character continue; } //load the glyph map into the texture glTexSubImage2D(GL_TEXTURE_2D,0,x,0, gGlyph->bitmap.width, gGlyph->bitmap.rows, GL_ALPHA, GL_UNSIGNED_BYTE, gGlyph->bitmap.buffer); //move the "pen" down the strip x += gGlyph->bitmap.width; chars[i].ax = (float)(gGlyph->advance.x >> 6); chars[i].ay = (float)(gGlyph->advance.y >> 6); chars[i].bw = (float)gGlyph->bitmap.width; chars[i].bh = (float)gGlyph->bitmap.rows; chars[i].bl = (float)gGlyph->bitmap_left; chars[i].bt = (float)gGlyph->bitmap_top; chars[i].tx = (float)x/width; } printf("Loaded font: %s\n",sFont.c_str()); return true; } void Draw(std::string sString,Vector2f vPos = Vector2f(0,0),Vector2f vScale = Vector2f(1,1)) { struct pPoint { pPoint() { x = y = s = t = 0; } pPoint(float a,float b,float c,float d) { x = a; y = b; s = c; t = d; } float x,y; float s,t; }; pPoint* cCoordinates = new pPoint[6*sString.length()]; int n = 0; for (const char *p = sString.c_str(); *p; p++) { float x2 = vPos.x() + chars[*p].bl * vScale.x(); float y2 = -vPos.y() - chars[*p].bt * vScale.y(); float w = chars[*p].bw * vScale.x(); float h = chars[*p].bh * vScale.y(); float x = vPos.x() + chars[*p].ax * vScale.x(); float y = vPos.y() + chars[*p].ay * vScale.y(); //skip characters with no pixels //still advances though if (!w || !h) { continue; } //triangle one cCoordinates[n++] = pPoint( x2 , -y2 , chars[*p].tx , 0); cCoordinates[n++] = pPoint( x2+w , -y2 , chars[*p].tx + chars[*p].bw / w , 0); cCoordinates[n++] = pPoint( x2 , -y2-h , chars[*p].tx , chars[*p].bh / h); cCoordinates[n++] = pPoint( x2+w , -y2 , chars[*p].tx + chars[*p].bw / w , 0); cCoordinates[n++] = pPoint( x2 , -y2-h , chars[*p].tx , chars[*p].bh / h); cCoordinates[n++] = pPoint( x2+w , -y2-h , chars[*p].tx + chars[*p].bw / w , chars[*p].bh / h); } glBindBuffer(GL_ARRAY_BUFFER,iVerts); glBindBuffer(GL_TEXTURE_2D,iTexture); //Vertices glEnableClientState(GL_VERTEX_ARRAY); glVertexPointer(2,GL_FLOAT,sizeof(pPoint),&cCoordinates[0].x); //TexCoord 0 glClientActiveTexture(GL_TEXTURE0); glEnableClientState(GL_TEXTURE_COORD_ARRAY); glTexCoordPointer(2,GL_FLOAT,sizeof(pPoint),&cCoordinates[0].s); glCullFace(GL_NONE); glBufferData(GL_ARRAY_BUFFER,6*sString.length(),cCoordinates,GL_DYNAMIC_DRAW); glDrawArrays(GL_TRIANGLES,0,n); glCullFace(GL_BACK); glBindBuffer(GL_ARRAY_BUFFER,0); glBindBuffer(GL_TEXTURE_2D,0); glDisableClientState(GL_VERTEX_ARRAY); glDisableClientState(GL_TEXTURE_COORD_ARRAY); } ~Font() { glDeleteBuffers(1,&iVerts); glDeleteBuffers(1,&iTexture); } private: unsigned int iSize; //openGL texture atlas unsigned int iTexture; //openGL geometry buffer; unsigned int iVerts; FT_Library ftLibrary; FT_Face ftFace; struct Character { float ax,ay;//Advance float bw,bh;//bitmap size float bl,bt;//bitmap left and top float tx; } chars[128]; };

• Google fonts different size and jagged

  - by capola

  I have one very surprising issue with Google Fonts. This is the site in question. The title is normaly showing in one ligne but a friend of mine with the same Opera version like me sent me this screenshot. You can see that the title goes in two lines and brakes every think. It's the first time I use Gfonts and must admit that there is another problem in Firefox too - the font appears so jagged! Thanks for your advises!

• Interface Photoshop size for iPhone app

  - by Sorin M

  Hello, I am building an iPhone app interface and I know the dpi has to be 163, but when it comes to the size of the file, I was looking through all the recommendations and found 2 different answers... Does anyone know what size should i set the Photoshop file at? The answers I have so far are: "The screen on the iPhone is 480×320, minus the 20-pixel status bar (making a 460×320 working screen size). The screen shots on the App Store should not include the status bar." "400 x 320 or 960 x 640 (iPhone 4) You must also consider the landscape mode (320 x 400 and 640 x 960)" I would really appreciate the answer. Thanks!

• Dijit.Dialog 1.4, setting size is limited to 600x400 no matter what size I set it.

  - by John Evans

  I'm trying to set the size of a dijit.Dialog, but it seems limited to 600x400, no matter what size I set it. I've copied the code from dojocampus and the dialog appear, but when i set the size larger, it only shows 600x400. Using firebug and selecting items inside the dialog, I see that they are larger than the dialog, but don't show correctly. I set it up to scroll, but the bottom of the scrollbar is out of view. In firebug, I've check the maxSize from _Widget and it is set to infinity. Here is my code to set the dialog. <div id="sized" dojoType="dijit.Dialog" title="My scrolling dialog"> <div style="width: 580px; height: 600px; overflow: scroll;"> Any suggestions for sizing the dialog box larger?

• Calculating the pixel size of a string with Python

  - by Aristide

  I have a Python script which needs to calculate the exact size of arbitrary strings displayed in arbitrary fonts in order to generate simple diagrams. I can easily do it with Tkinter. The problem is the results seem to depend on the version of Python and/or the system. import Tkinter as tk import tkFont root = tk.Tk() times12 = tkFont.Font(family="times",size=12) print times12.metrics("linespace"), print times12.measure("Hello world") times24 = tkFont.Font(family="times",size=24) print times24.metrics("linespace"), print times24.measure("Hello world") Python 2.5 on Mac OS X gives the actual pixel measurements: 12 57 24 116 Python 2.6.1 on Mac OS X gives: 14 58 27 115 Python 2.6.3 on Windows XP gives: 19 71 36 154 Such a need being quite common, I suspect I did something wrong. Any idea?

• In C, as free() knows an array size, why isn't there a function that gets the array size? [closed]

  - by user354959

  Possible Duplicate: If free() knows the length of my array, why can’t I ask for it in my own code? Searching around (including here at stackoverflow), I got that malloc() allocates an array and also creates a header to control the array info. In this header, there's also the array size. free() use such information to know how to deallocate that array. So, if the array size info is "there" (somewhere in the memory), why there isn't a function that returns an array size, looking for this at the array header? Or am I missing something?

• Differing form size between XP and 7

  - by Andy

  I am developing a C# WinForms app on my XP dev machine with Visual C# Express 2008. I set the form to have a size of my liking with Width and Height on the designer and all looks good. I also set these dimensions to the MaximumSize property. Deploying the app to another XP machine, and the app looks like it does on my dev. However, in testing the app on a Win7 machine, the form has both horizontal and vertical scrollbars applied. I assume that this is due to the changed non-client size of the form, as determined by Win7. I can resize the window, but I would like it to be displayed correctly to begin with. So, my question is: What is the best way to correctly maintain a form size client area across OS'es? Thanks all.

• Arch linux, openbox Monaco font problem

  - by z33m

  Im trying to setup a minimal desktop with openbox window manager on Arch linux. I noticed these weird font rendering issues with Monaco font. Below font size 13, alternate font sizes are rendered in an aliased, ugly manner. The same Arch installation has no problem rendering Monaco font when running under xfce. some of the characters even look completely different. I tried tweaking my .fonts.conf, but no luck.
