• Java Convert ColorSpace of BufferedImage to CS_GRAY without using ConvertColorOp

  - by gmatt

  I know its possible to convert an image to CS_GRAY using public static BufferedImage getGrayBufferedImage(BufferedImage image) { BufferedImageOp op = new ColorConvertOp(ColorSpace .getInstance(ColorSpace.CS_GRAY), null); BufferedImage sourceImgGray = op.filter(image, null); return sourceImgGray; } however, this is a chokepoint of my entire program. I need to do this often, on 800x600 pixel images and takes about 200-300ms for this operation to complete, on average. I know I can do this alot faster by using one for loop to loop through the image data and set it right away. The code above on the other hand constructs a brand new 800x600 BufferedImage that is gray scale. I would rather just transform the image I pass in. Does any one know how to do this with a for loop and given that the image is RGB color space?

• In Delphi, Is there a way to adjust the line spacing of a TMemo?

  - by Kieran

  I'm working with a TMemo component to display some text in a limited space. Currently it's using a truetype font which doesn't ship with windows and is installed by the app when it runs. On my PC (Running Windows XP), the spacing between each line of text seems to be about eight pixels. On a different PC running Windows 7, the line spacing seems to be about 14 pixels, which is pushing the bottom row of text out of visibility on the memo. So, My question is really this: Is this caused by the different versions of Windows? It's all I could think that was different. Is there some way I can adjust this value so it would be consistent across all instances of the application, wherever it was running? Alternatatively, is there a different component I could use which might let me tweak this value?

• possible bug in geom_ribbon

  - by tomw

  i was hoping to plot two time series and shade the space between the series according to which series is larger at that time. here are the two series-- first in a data frame with an indicator for whichever series is larger at that time d1 <- read.csv("https://dl.dropbox.com/s/0txm3f70msd3nm6/ribbon%20data.csv?dl=1") And this is the melted series. d2 <- read.csv("https://dl.dropbox.com/s/6ohwmtkhpsutpig/melted%20ribbon%20data.csv?dl=1") which I plot... ggplot() + geom_line(data = d2, aes(x = time, y = value, group = variable, color = variable)) + geom_hline(yintercept = 0, linetype = 2) + geom_ribbon(data = d1[d1$big == "B",], aes(x = time, ymin = csa, ymax = csb), alpha = .25, fill = "#9999CC") + geom_ribbon(data = d1[d1$big == "A",], aes(x = time, ymin = csb, ymax = csa), alpha = .25, fill = "#CC6666") + scale_color_manual(values = c("#CC6666" , "#9999CC")) which results in... why is there a superfluous blue band in the middle of the plot?

• Replace underscore between words (reg.exp)

  - by lasseespeholt

  Hey, I need a regular expression to solve the following problem (links to similar problems is also appreciated, related tutorials etc.): __some_words_a_b___ => __some words a b___ ____ => ____ So I want underscores between words to be replaced with space and keep leading and trailing underscores. I found this: ^[ \t]+|[ \t]+$ and I guess it most be something like that. I will use it in jQuery, Java (stdlibs) and maybe XSLT. Addition: The sentences do not necessarily start with underscores or ends with underscores. It is also possible that a sentence ain't containing underscores at all. Best regards Lasse Espeholt

• Program seems to get stuck ?

  - by Frank

  I have a Java program, I did some change and the strange thing is no matter what I do now, it will output the same result before my change, I looked into my system (Windows Vista), and clicked on "Generate a system health report", the result says : Symptom : A service is reported as having an unexpected error code Cause : One or more services has failed. The service did not stop gracefully, suggesting the service may have crashed or one of its components stopped in an unsupported way. Details : Service exited with code not equal to 0 or 1077 Resolution : Restart the service It doesn't say which service, and I defragmented my drives a few times, it still gave me the same report. I also checked my memory, it says no problem with ram. Everything else is ok, I re-started the windows a few times, got more free space on my C: drive, yet the Java program is still not responding to my new changes, unless I intentionally make a mistake, it gives me compile error, but if it can compile successfully, it still gives me the results before the change. What can I do to fix this ? Frank

• How can I use gnuplot to plot data that is in an un-friendly format?

  - by Zack

  I need to graph some data that is not exactly in the most friendly format, most examples or usage puts things in a nice column/table that is very easy to parse and graph. However I have the following format (and am a bit stuck as to how to tackle this): DATE1 label_1 xx yy DATE1 label_2 xx yy DATE1 label_3 xx yy DATE2 label_2 xx yy DATE2 label_3 xx yy DATE3 label_1 xx yy DATE3 label_2 xx yy DATE3 label_3 xx yy DATE4 label_2 xx yy DATE4 label_3 xx yy ...continues *I've added the extra space between the dates for readability. **Note: under DATE2,DATE4 label_1 is missing, i.e. the data file may have labels that come and go and should represent a discontinuity in the graph. I'd like to have the X-axis use the DATEX for the labels, and then create two lines for each label (xx and yy respectively). Does anyone have any suggestions on the best way to tackle this problem?

• matplotlib.pyplot, preserve aspect ratio of the plot

  - by Headcrab

  Assuming we have a polygon coordinates as polygon = [(x1, y1), (x2, y2), ...], the following code displays the polygon: import matplotlib.pyplot as plt plt.fill(*zip(*polygon)) plt.show() By default it is trying to adjust the aspect ratio so that the polygon (or whatever other diagram) fits inside the window, and automatically changing it so that it fits even after resizing. Which is great in many cases, except when you are trying to estimate visually if the image is distorted. How to fix the aspect ratio to be strictly 1:1? (Not sure if "aspect ratio" is the right term here, so in case it is not - I need both X and Y axes to have 1:1 scale, so that (0, 1) on both X and Y takes an exact same amount of screen space. And I need to keep it 1:1 no matter how I resize the window.)

• What regular expression do I need to check for some non-latin characters?

  - by zeckdude

  I am checking a field if it is Latin Characters or not. var foreignCharacters = $("#foreign_characters").val(); var rlatins = /[\u0000-\u007f]/; if (rlatins.test(foreignCharacters)) { alert("This is Latin Characters"); } else { alert("This is non-latin Characters"); } This works well, but I would like to change it so when I enter any non-latin characters, such as chinese characters, along with a space(which is within that range I am using currently) it will still say it is non-latin characters. How can I change the regular expression I have to do that?

• Replace CR/LF in a text file only after a certain column

  - by Olav

  I have a large text file I would like to put on my ebook-reader, but the formatting becomes all wrong because all lines are hard wrapped at or before column 80 with CR/LF, and paragraphs/headers are not marked differently, only a single CR/LF there too. What I would like is to replace all CR/LF's after column 75 with a space. That would make most paragraphs continuous. (Not a perfect solution, but a lot better to read.) Is it possible to do this with a regex? Preferably a (linux) perl or sed oneliner, alternatively a Notepad++ regex.

• Storing n-grams in database in < n number of tables.

  - by kurige

  If I was writing a piece of software that attempted to predict what word a user was going to type next using the two previous words the user had typed, I would create two tables. Like so: == 1-gram table == Token | NextWord | Frequency ------+----------+----------- "I" | "like" | 15 "I" | "hate" | 20 == 2-gram table == Token | NextWord | Frequency ---------+------------+----------- "I like" | "apples" | 8 "I like" | "tomatoes" | 12 "I hate" | "tomatoes" | 20 "I hate" | "apples" | 2 Following this example implimentation the user types "I" and the software, using the above database, predicts that the next word the user is going to type is "hate". If the user does type "hate" then the software will then predict that the next word the user is going to type is "tomatoes". However, this implimentation would require a table for each additional n-gram that I choose to take into account. If I decided that I wanted to take the 5 or 6 preceding words into account when predicting the next word, then I would need 5-6 tables, and an exponentially increase in space per n-gram. What would be the best way to represent this in only one or two tables, that has no upper-limit on the number of n-grams I can support?

• Which SOA architecture is most appropriate for a Java application?

  - by Robert Greiner

  I am currently working on a pretty large Java 6 application where we are looking to split some of our functionality out into a service oriented architecture. It seems that the primary SOA framework for the application space is OSGi and I have been looking into Felix and Knopplerfish but I wanted to make sure that this isn't my only option. Does it make sense to use an actual web service protocol for our application like SOAP, even though we are not building a web app? Is this even acceptable? Have any of you used an implementation of OSGi (Felix, etc.) with your desktop application? if so, how did it go? Do you know of anything better? We're all pretty new to SOA here so any help would be greatly appreciated.

• A specific string format with a number and character together represeting a certain item

  - by sil3nt

  Hello there, I have a string which looks like this "a 3e,6s,1d,3g,22r,7c 3g,5r,9c 19.3", how do I go through it and extract the integers and assign them to its corresponding letter variable?. (i have integer variables d,r,e,g,s and c). The first letter in the string represents a function, "3e,6s,1d,3g,22r,7c" and "3g,5r,9c" are two separate containers . And the last decimal value represents a number which needs to be broken down into those variable numbers. my problem is extracting those integers with the letters after it and assigning them into there corresponding letter. and any number with a negative sign or a space in between the number and the letter is invalid. How on earth do i do this?

• Holy grail layout with 100% height

  - by Henrik Skogmo

  I am trying to make a css layout that looks like this http://oi53.tinypic.com/o0v0vp.jpg The CSS term for this type of layout is known as the "holy grail" I think. The problem I am facing is that when I use layouts and solutions I find online I do not get them to work properly as I want them to. What I am trying to do is make a page that, regardless of content, will have the footer at the bottom of the browser and the columns stretching down to it. So far I have only seen pages that have the footer placed where the content stop, the result is some blank space under the footer. If anyone could help me out on this it would be greatly appreciated!

• How to remove the title bar from a JFrame screenshot?

  - by Greg Harman

  I'm capturing a screenshot image of a JFrame via a "double buffering" approach, per below: public BufferedImage getScreenshot() { java.awt.Dimension dim = this.getPreferredSize(); BufferedImage image = new BufferedImage(dim.width, dim.height, BufferedImage.TYPE_INT_RGB); this.paint(image.getGraphics()); return image; } where this extends JFrame. The image that I get has a blank strip along the top where the title bar was. What's the most straightforward way to capture an image of the contents of the JFrame without the extra space allocated for the title bar?

• How to create windows form to display properly in all monitors?

  - by Madhu

  I have created a windows form using (vs.net 2008 and vb.net as programming lanugage). Functionality part is working fine as expected. My issues is that, when i run my application in different machines, the form display is not proper accross the monitory screen. In some machines i noticed extra space on leftside of the container. In some other machine's it is vice versa. If you maximize or restore the form, the size varies. I tried to check the window form design on different machines using visual studio 2008, there also the form design looks differently. Please give me the solution to fix this issue. Thanks in advance.

• How can I search for numbers in a varchar column

  - by dave

  I've got a simple nvarchar(25) column in an SQL database table. Most of the time, this field should contain alphanumeric text. However, due to operator error, there are many instances where it contains only a number. Can I do a simple search in SQL to identify these cases? That is, determine which rows in the table contain only digits in this column. As an extension, could I also search for those column values which contain only digits and a space and/or slash. In other languages (eg. Perl, Java) a regular expression would resolve this quickly and easily. But I haven't been able to find the equivalent in SQL.

• Assigned numbers to movie clip to plug in formula... not working

  - by Matthew MlgPro Harding

  So I am attempting to vertically evenly space these movie clips so I came up with a math formula involving n( the button number) but Its not working. var buttonArray:Array = [ side_banner.btn1, side_banner.btn2, side_banner.btn3, side_banner.btn4]; var buttonCount:uint = buttonArray.length; for (var i:uint=0; i< buttonCount; i++) { buttonArray[i].addEventListener(MouseEvent.CLICK, outputNumber); buttonArray[i].theTrigger = [i + 1]; } function outputNumber(e:MouseEvent):void { trace( e.target.theTrigger); buttonArray[i].y = (((stage.stageHeight - 400)/4)*(e.target.theTrigger)) - ((stage.stageHeight - 400)/4)/2 } But apparently each movie clip doesn't actually have a numerical value just a numeric name... how can I get the "n" btn number to use my formula? Thanks

• Using install_name_tool what's going wrong?

  - by 0x80

  I'm trying to change the install path of a dylib after it has been build. I use "otool -L" to check what the current path is. And then I do: $ install_name_tool -change /my/current/path/libmine.dylib /my/new/path/libmine.dylib libmine.dylib I don't get an error, but nothing changes. If I check the path again the old one is still there. Also the new path is a lot shorter then the old one, so no problem there, and I think the lib is even compiled with extra flag for more filepath space. Any ideas?

• Blackberry - Custom size EditField

  - by Eric

  I am trying to put together a dialog that should look like this: Fill in the below fields ___________ likes ________________ where the "_" lines are the EditFields. I am sticking all the fields in a HorizontalFieldManager, which I add to the dialog. Unfortunately, the first EditField consumes all the space on the first line. I have tried to override the getPreferredWidth() method of the EditField by creating my own class extending BasicEditField, but have had no success. Surely there must be a simple way to force a certain size for an edit field. What am I missing?

• Deferring signal handling in Linux

  - by EpsilonVector

  I'm trying to figure out how to block a signal in Linux kernel 2.4 (user space) from invoking its handler, but keep it available to be handled later, preferably as soon as I re activate the handling of said signal. The function sigprocmask seem to come up in all my search results, but I can't find a good, clear description that explains whether the blocked signal gets "saved" to be handled later, and if so where and how do I handle it when I'm ready for it. Can someone please clarify what's going on, preferably with a code example? Thanks in advance.

• mdadm: Win7-install created a boot partition on one of my RAID6 drives. How to rebuild?

  - by EXIT_FAILURE

  My problem happened when I attempted to install Windows 7 on it's own SSD. The Linux OS I used which has knowledge of the software RAID system is on a SSD that I disconnected prior to the install. This was so that windows (or I) wouldn't inadvertently mess it up. However, and in retrospect, foolishly, I left the RAID disks connected, thinking that windows wouldn't be so ridiculous as to mess with a HDD that it sees as just unallocated space. Boy was I wrong! After copying over the installation files to the SSD (as expected and desired), it also created an ntfs partition on one of the RAID disks. Both unexpected and totally undesired! . I changed out the SSDs again, and booted up in linux. mdadm didn't seem to have any problem assembling the array as before, but if I tried to mount the array, I got the error message: mount: wrong fs type, bad option, bad superblock on /dev/md0, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so dmesg: EXT4-fs (md0): ext4_check_descriptors: Block bitmap for group 0 not in group (block 1318081259)! EXT4-fs (md0): group descriptors corrupted! I then used qparted to delete the newly created ntfs partition on /dev/sdd so that it matched the other three /dev/sd{b,c,e}, and requested a resync of my array with echo repair > /sys/block/md0/md/sync_action This took around 4 hours, and upon completion, dmesg reports: md: md0: requested-resync done. A bit brief after a 4-hour task, though I'm unsure as to where other log files exist (I also seem to have messed up my sendmail configuration). In any case: No change reported according to mdadm, everything checks out. mdadm -D /dev/md0 still reports: Version : 1.2 Creation Time : Wed May 23 22:18:45 2012 Raid Level : raid6 Array Size : 3907026848 (3726.03 GiB 4000.80 GB) Used Dev Size : 1953513424 (1863.02 GiB 2000.40 GB) Raid Devices : 4 Total Devices : 4 Persistence : Superblock is persistent Update Time : Mon May 26 12:41:58 2014 State : clean Active Devices : 4 Working Devices : 4 Failed Devices : 0 Spare Devices : 0 Layout : left-symmetric Chunk Size : 4K Name : okamilinkun:0 UUID : 0c97ebf3:098864d8:126f44e3:e4337102 Events : 423 Number Major Minor RaidDevice State 0 8 16 0 active sync /dev/sdb 1 8 32 1 active sync /dev/sdc 2 8 48 2 active sync /dev/sdd 3 8 64 3 active sync /dev/sde Trying to mount it still reports: mount: wrong fs type, bad option, bad superblock on /dev/md0, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so and dmesg: EXT4-fs (md0): ext4_check_descriptors: Block bitmap for group 0 not in group (block 1318081259)! EXT4-fs (md0): group descriptors corrupted! I'm a bit unsure where to proceed from here, and trying stuff "to see if it works" is a bit too risky for me. This is what I suggest I should attempt to do: Tell mdadm that /dev/sdd (the one that windows wrote into) isn't reliable anymore, pretend it is newly re-introduced to the array, and reconstruct its content based on the other three drives. I also could be totally wrong in my assumptions, that the creation of the ntfs partition on /dev/sdd and subsequent deletion has changed something that cannot be fixed this way. My question: Help, what should I do? If I should do what I suggested , how do I do that? From reading documentation, etc, I would think maybe: mdadm --manage /dev/md0 --set-faulty /dev/sdd mdadm --manage /dev/md0 --remove /dev/sdd mdadm --manage /dev/md0 --re-add /dev/sdd However, the documentation examples suggest /dev/sdd1, which seems strange to me, as there is no partition there as far as linux is concerned, just unallocated space. Maybe these commands won't work without. Maybe it makes sense to mirror the partition table of one of the other raid devices that weren't touched, before --re-add. Something like: sfdisk -d /dev/sdb | sfdisk /dev/sdd Bonus question: Why would the Windows 7 installation do something so st...potentially dangerous? Update I went ahead and marked /dev/sdd as faulty, and removed it (not physically) from the array: # mdadm --manage /dev/md0 --set-faulty /dev/sdd # mdadm --manage /dev/md0 --remove /dev/sdd However, attempting to --re-add was disallowed: # mdadm --manage /dev/md0 --re-add /dev/sdd mdadm: --re-add for /dev/sdd to /dev/md0 is not possible --add, was fine. # mdadm --manage /dev/md0 --add /dev/sdd mdadm -D /dev/md0 now reports the state as clean, degraded, recovering, and /dev/sdd as spare rebuilding. /proc/mdstat shows the recovery progress: md0 : active raid6 sdd[4] sdc[1] sde[3] sdb[0] 3907026848 blocks super 1.2 level 6, 4k chunk, algorithm 2 [4/3] [UU_U] [>....................] recovery = 2.1% (42887780/1953513424) finish=348.7min speed=91297K/sec nmon also shows expected output: ¦sdb 0% 87.3 0.0| > |¦ ¦sdc 71% 109.1 0.0|RRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR > |¦ ¦sdd 40% 0.0 87.3|WWWWWWWWWWWWWWWWWWWW > |¦ ¦sde 0% 87.3 0.0|> || It looks good so far.

• Is there anyone out there that codes like I do?

  - by Jacob Relkin

  Hi, Some people have told me that my coding style is a lot different than theirs. I think I am somewhat neurotic when it comes to spacing and indenting though. Here's a snippet to show you what I mean: - ( void ) applicationDidFinishLaunching: ( UIApplication *) application { SomeObject *object = [ [ SomeObject alloc ] init ]; int x = 100 / 5; object.someInstanceVariable = ( ( 4 * x ) + rand() ); [ object someMethod ]; } Notice how I space out all of my brackets/parentheses, start curly braces on the same line, "my code has room to breathe", so to speak. So my questions are a) is this normal and b) What's your coding style?

• The best way to display data in a table view?

  - by LawVS

  Hey guys, I'm trying to display nutritional information in a table view but am struggling about the best way to show the info. I don't want to create unique views for each page as that would take up a lot of space. My ideal avenue would be like a website having links to data pages instead of individual views for each page. How would I best implement that? For example, I would want the first page to be a list of restaurants, then as you press the restaurant it would list the different types of food...the next page would be a list of those foods and then the final page would be the nutrition info itself. Thanks
