  • How do I make my Boot Camp partition bootable again?

    - by Dan Herbert
    I needed to resize my Boot Camp partition so I used Gparted to move and resize it. This seemed to work, except that now I can't boot into Windows. I can boot into OS X just fine. OS X can recognize the Boot Camp partition and view its contents. When I try to reboot into Windows, however I get the message: No bootable device -- insert boot disk and press any key The only solutions I've been able to find online suggest that the only way to fix this is to either clone the drive or remove the Windows partition and re-install it. Is there any way to fix my Windows partition so that I don't have to reinstall Windows again?

  • JUnit: checking if a void method gets called

    - by nkr1pt
    I have a very simple filewatcher class which checks every 2 seconds if a file has changed and if so, the onChange method (void) is called. Is there an easy way to check ik the onChange method is getting called in a unit test? code: public class PropertyFileWatcher extends TimerTask { private long timeStamp; private File file; public PropertyFileWatcher(File file) { this.file = file; this.timeStamp = file.lastModified(); } public final void run() { long timeStamp = file.lastModified(); if (this.timeStamp != timeStamp) { this.timeStamp = timeStamp; onChange(file); } } protected void onChange(File file) { System.out.println("Property file has changed"); } } @Test public void testPropertyFileWatcher() throws Exception { File file = new File("testfile"); file.createNewFile(); PropertyFileWatcher propertyFileWatcher = new PropertyFileWatcher(file); Timer timer = new Timer(); timer.schedule(propertyFileWatcher, 2000); FileWriter fw = new FileWriter(file); fw.write("blah"); fw.close(); Thread.sleep(8000); // check if propertyFileWatcher.onChange was called file.delete(); }

  • Parse JSON into a ListView friendly output

    - by Thomas McDonald
    So I have this JSON, which then my activity retrieves to a string: {"popular": {"authors_last_month": [ { "url":"http://activeden.net/user/OXYLUS", "item":"OXYLUS", "sales":"1148", "image":"http://s3.envato.com/files/15599.jpg" }, { "url":"http://activeden.net/user/digitalscience", "item":"digitalscience", "sales":"681", "image":"http://s3.envato.com/files/232005.jpg" } { ... } ], "items_last_week": [ { "cost":"4.00", "thumbnail":"http://s3.envato.com/files/227943.jpg", "url":"http://activeden.net/item/christmas-decoration-balls/75682", "sales":"43", "item":"Christmas Decoration Balls", "rating":"3", "id":"75682" }, { "cost":"30.00", "thumbnail":"http://s3.envato.com/files/226221.jpg", "url":"http://activeden.net/item/xml-flip-book-as3/63869", "sales":"27", "item":"XML Flip Book / AS3", "rating":"5", "id":"63869" }, { ... }], "items_last_three_months": [ { "cost":"5.00", "thumbnail":"http://s3.envato.com/files/195638.jpg", "url":"http://activeden.net/item/image-logo-shiner-effect/55085", "sales":"641", "item":"image logo shiner effect", "rating":"5", "id":"55085" }, { "cost":"15.00", "thumbnail":"http://s3.envato.com/files/180749.png", "url":"http://activeden.net/item/banner-rotator-with-auto-delay-time/22243", "sales":"533", "item":"BANNER ROTATOR with Auto Delay Time", "rating":"5", "id":"22243"}, { ... }] } } It can be accessed here as well, although it because it's quite a long string, I've trimmed the above down to display what is needed. Basically, I want to be able to access the items from "items_last_week" and create a list of them - originally my plan was to have the 'thumbnail' on the left with the 'item' next to it, but from playing around with the SDK today it appears too difficult or impossible to achieve this, so I would be more than happy with just having the 'item' data from 'items_last_week' in the list. Coming from php I'm struggling to use any of the JSON libraries which are available to Java, as it appears to be much more than a line of code which I will need to deserialize (I think that's the right word) the JSON, and they all appear to require some form of additional class, apart from the JSONArray/JSONObject script I have which doesn't like the fact that items_last_week is nested (again, I think that's the JSON terminology) and takes an awful long time to run on the Android emulator. So, in effect, I need a (preferably simple) way to pass the items_last_week data to a ListView. I understand I will need a custom adapter which I can probably get my head around but I cannot understand, no matter how much of the day I've just spent trying to figure it out, how to access certain parts of a JSON string..

  • Add gridlines to a output plot in Mathemaitca

    - by xslittlegrass
    I'm trying to add gridlines to a output density plot in Mathematica. The plot is generated by a long calculation in Mathematica and when I do the plot I forget to add the Mesh-True options. I don't want to do all the calculation and generate the plot again since it takes a long time. Is that possible to add the gridlines or mesh lines to plot ONLY using the output plot at hand? For example, If I have a plot p. Is it possible to add the mesh lines ONLY manipulate p? In a ordinary one dimensional plot, this will work p1 = Plot[Sin[x], {x, -3, 3}]; Insert[p1, GridLines -> Automatic, -1] But when I try the density plot, it seems the gridlines is always under the plot, and can be seen only at the image margin area. p2 = DensityPlot[Sin[x + y^2], {x, -3, 3}, {y, -2, 2}, PlotRangePadding -> 0.2]; Insert[p2, GridLines -> Automatic, -1] Updata The Mesh option on the output plot will not work because Mesh is not a options of a Graphics: Show[p2,Mesh->True] will give a message "an unrecoginzed option name(Mesh) was encountered while rendering a Graphics" Thanks.

  • Simulating mouse clicks at specific screen coordinates

    - by Matteo Riva
    I would like to be able to bind some keys to mouse clicks done in specific locations. For example: when I press F1 I should get a left mouse click at coordinates 300x350, F2 at 600x350 and so on. Even better if this could be bound to a specific window application so that coordinates could be relative to it instead of the base desktop. Is there a software which allows this? ADDITION: Ok autohotkey is great but I have problems with my particular setup. Quoting my comment below: I'm using it with an old game (championship manager 01/02) which runs in windowed mode (and I have to set win98 compatibility for it to run): I can get the mouse to move but no click goes to the application I have read this FAQ but it didn't help, this is the script I tried: SendMode Play SetKeyDelay, 0, 50, Play F1::Click 42, 191 F2::ControlSend ahk_class main, Click, Championship Manager 01/02 Still no luck: pointer moves but no click goes through.

  • How to fix: mac keyboard ignores "first" key pressed

    - by lexu
    UPDATE 2012.03.19: the MBP described in this post is now broken and recycled (logic board fried). The replacement doesn't manifest the same problems. I tend to believe the problem originated in the keyboard firmware of the old MBP. Every now and then, usually after I haven't pressed a key in some time, sometimes minutes, sometimes seconds, my MBP will "swallow" the the first key I press ... say I'm logging into "superuser.com" .. I start typing my username and the textbox will show "exu" instead of "lexu" This is driving me nuts! My guess is the keyboard or it's controller goes to sleep and fails to wake up propperly ... What can I do about this? PS: I've already installed "MacBook, MacBook Pro Keyboard Firmware Update 1.0"

  • Properly configuring Linux keyboard on my laptop

    - by antoniocs
    Hey! I have a ps/2 keyboard connected to an Acer Aspire 1694 WLMI via a ps/2 to usb converter. The laptop is running Ubuntu 9.04. The keyboard is a HP model number: SK-250C. I have configured in the 'Keyboard Preferences' the layout to HP SK-250x Multimedia Keyboard. The big problem is when I press certain keys (like for example the arrow keys) I get the 'Save Screenshot' dialog. This is really getting annoying, sometimes I am tying to write an address in browser and just want to go back a few letters and can't. There are other keys that trigger the dialog also (windows key, insert key, home key, page up and page down key, delete key, end key) All works fine If I use the laptop keyboard, but I really want to use the HP keyboard. EDIT: I was testing this and it seems that if I have the 'Num Lock' key turned off the keys work properly. Strange but true!!

  • How do I fix "Setup did not find any hard disk drives installed in your computer" error during Win X

    - by CT
    I just bought a nettop. It came with WinXP Home. I first installed Win 7 on it. I wasn't that happy with the performance so I decided to go back to XP. I am using an external dvd drive and a Win XP Pro disc. I boot from the dvd drive and during the install get this error: Setup did not find any hard disk drives installed in your computer. Make sure any hard disk drives are powered on and properly connected to your computer, and that any disk-related hardware configuration is correct. This may involve running a manufacturer-supplied diagnostic or setup program. Setup cannot continue. To quit Setup, press F3.

  • Automatically mount a remote folder on boot

    - by Andrew
    I'm trying to mount a Windows folder on my Ubuntu machine on start up. I've tried following this page here, modifying /etc/fstab and appending sshfs#my_user@remote_host:/path/to/directory <local_mount_point> fuse user 0 0 to it, but it fails; on start up, I get an error saying that the mounting failed, and I can press S to skip or M to recover manually. I also tried following this page here, appending /usr/bin/sshfs -o idmap=user my_user@remote_host:/path/to/directory <local_mount_point> to the /etc/rc.local file, but this doesn't help either; Ubuntu just boots up normally without mounting. I have Cygwin installed on my Windows machine, and I can run everything smoothly, such as sshing without passwords, and mounting it manually. I've also tried to run the modified rc.local file $ /etc/rc.local, and it works perfectly, but I just can't seem to get the folder mounted on start up. Can someone help me?

Do I need to do anything to the sass file for compass to work. Thanks

  • WesternDigital SmartWare - still problematic?

    - by FrustratedWithFormsDesigner
    I've seen a lot of bad press on WD SmartWare (I think it comes on most WD backup devices now, such as their MyBook product line), mostly related to how it's impossible to remove properly or replace. There are allegations (I couldn't tell how true they were) that it has/is a rootkit, as well. Most of the articles are a couple of years old, so I'm wondering if SmartWare is still just as problematic as it was. Does it still have a nasty rootkit reputation and should I just stick with the Windows 7 built-in backup system, or is the current SmartWare generation improved and better behaved?

  • Hashtable resizing leaks memory

    - by thpetrus
    I wrote a hashtable and it basically consists of these two structures: typedef struct dictEntry { void *key; void *value; struct dictEntry *next; } dictEntry; typedef struct dict { dictEntry **table; unsigned long size; unsigned long items; } dict; dict.table is a multidimensional array, which contains all the stored key/value pair, which again are a linked list. If half of the hashtable is full, I expand it by doubling the size and rehashing it: dict *_dictRehash(dict *d) { int i; dict *_d; dictEntry *dit; _d = dictCreate(d->size * 2); for (i = 0; i < d->size; i++) { for (dit = d->table[i]; dit != NULL; dit = dit->next) { _dictAddRaw(_d, dit); } } /* FIXME memory leak because the old dict can never be freed */ free(d); // seg fault return _d; } The function above uses the pointers from the old hash table and stores it in the newly created one. When freeing the old dict d a Segmentation Fault occurs. How am I able to free the old hashtable struct without having to allocate the memory for the key/value pairs again?

  • Do complex JOINs cause high coupling and maintenance problems ?

    - by ashkan.kh.nazary
    Our project has ~40 tables with complex relations.A colleague believes in using long join queries which enforces me to learn about tables outside of my module but I think I should not concern about tables not directly related to my module and use data access functions (written by those responsible for other modules) when I need data from them. Let me clarify: I am responsible for the ContactVendor module which enables the customers to contact the vendor and start a conversation about some specific product. Products module has it's own complex tables and relations with functions that encapsulate details (for example i18n, activation, product availability etc ...). Now I need to show the product title of some product related to some conversation between the vendor and customers. I may either write a long query that retrieves the product info along with conversation stuff in one shot (which enforces me to learn about Product tables) OR I may pass the relevant product_id to the get_product_info(int) function. First approach is obviously demanding and introduces many bad practices and things I normally consider fault in programming. The problem with the second approach seems to be the countless mini queries these access functions cause and performance loss is a concern when a loop tries to fetch product titles for 100 products using functions that each perform a separate query. So I'm stuck between "don't code to the implementation, code to interface" and performance. What is the right way of doing things ? UPDATE: I'm specially concerned about possible future modifications to those tables outside of my module. What if the Products module decided to change the way they are doing things? or for some reason modify the schema? It means some other modules would break or malfunction until the change is integrated to them. The usual ripple effect problem.

  • JPA joined column allow every value...

    - by Fabio Beoni
    I'm testing JPA, in a simple case File/FileVersions tables (Master/Details), with OneToMany relation, I have this problem: in FileVersions table, the field "file_id" (responsable for the relation with File table) accepts every values, not only values from File table. How can I use the JPA mapping to limit the input in FileVersion.file_id only for values existing in File.id? My class are File and FileVersion: FILE CLASS @Id @GeneratedValue(strategy = GenerationType.IDENTITY) @Column(name="FILE_ID") private Long id; @Column(name="NAME", nullable = false, length = 30) private String name; //RELATIONS ------------------------------------------- @OneToMany(mappedBy="file", fetch=FetchType.EAGER) private Collection <FileVersion> fileVersionsList; //----------------------------------------------------- FILEVERSION CLASS @Id @GeneratedValue(strategy = GenerationType.IDENTITY) @Column(name="VERSION_ID") private Long id; @Column(name="FILENAME", nullable = false, length = 255) private String fileName; @Column(name="NOTES", nullable = false, length = 200) private String notes; //RELATIONS ------------------------------------------- @ManyToOne(fetch=FetchType.EAGER) @JoinColumn(name="FILE_ID", referencedColumnName="FILE_ID", nullable=false) private File file; //----------------------------------------------------- and this is the FILEVERSION TABLE CREATE TABLE `JPA-Support`.`FILEVERSION` ( `VERSION_ID` bigint(20) NOT NULL AUTO_INCREMENT, `FILENAME` varchar(255) NOT NULL, `NOTES` varchar(200) NOT NULL, `FILE_ID` bigint(20) NOT NULL, PRIMARY KEY (`VERSION_ID`), KEY `FK_FILEVERSION_FILE_ID` (`FILE_ID`) ) ENGINE=MyISAM AUTO_INCREMENT=4 DEFAULT CHARSET=latin1

  • Inserting new 'numbered item' on Word 2010

    - by MarceloRamires
    I have a very simple problem in Word 2010. I have a document with a Table of Contents, and I have the following items: 1. Title 1  [some text]   1.1 Title 1.1    [some text] I simply want to add an item 1.2. If I go at the end of Title 1.1 and press enter, an item 1.2 appears below it, but the text regarding item 1.1 stays below it all. I somehow used to be able to do it on word 2007, but I can't remember what I used to do, and before struggling in it for too long, I remembered SuperUser. Can someone answer this and maybe additionally link me to a tutorial on this ? Every one I find talks about having a text already numbered and adding a TOC in the beginning. I want to build the text all over the TOC.

  • How can I get Gnome-Do to open in multiple X Screens?

    - by btelles
    Hi, I LOVE Gnome-Do (the Ubuntu version of QuickSilver). The only thing is that I have several monitors, which are all completely separate X Screens (I.E. I can't move windows between them), and Gnome-Do will only open in ONE of those monitors. If I go to Monitor/Screen #2 and press Super+Space, the Gnome-Do window appears in the first monitor. Is it possible to get a separate Instance of Gnome-Do on each Screen? P.S. Using profiles may be a work-around...I've managed to get multiple instances of Firefox by using "firefox -P my_first_screen"...anything like that available in Gnome-do?

  • Ubuntu server hangs on reboot "could not stat resume device file"

    - by matnagel
    Instead of booting into the running system this machine stops and on the terminal I can see a message: could not stat resume device file /dev/sdb5 When I attach a keyboard and press enter the boot continues and the machine comes up like normal. But it's essential that this machine comes up under most circumstancs alone. There never was something like a "resume" on this machine. I tried several times to reboot, but this does not happen on all boots, I can not find a pattern here. There is a software raid running on the box. This is the syslog during boot: http://privatepaste.com/ff0fd0a51c/sdabfjahfgasjkgfu4gfsdzjcgfafasdjfhgasdcjfgauzfgafasgdufzg How can I get rid of this boot failure? We do not need resumes and best would be something that works here and now.

  • Windows 7, files reappear after deletion.

    - by HeavyWave
    I'm trying to delete some files from a folder. I've taken ownership of the files and the folder. When I delete these files Windows doesn't report any errors and deletes them. BUT, after I press F5 these files reappear again. There are no messages whatsoever, they are just undeletable. I know login off will help, but how do I fix it without going through the pain of closing everything down? P.S. Files disappear from the folder after aprox. 5 minutes. Update. Turns out my version of Windows did not properly upgrade from test version, so it had some weird disk drive issues.

  • Visual Studio Linked Files Directory Structure

    - by jeffn825
    I have two versions of a project. One for Silverlight and one for .NET. The SL project has the vast majority of the code base in it. I want to globally add all files from the SL project into the .NET version as linked files. I've managed to do so successfully like this in the csproj file for the .NET version: <Compile Include="..\MyProj.Common.SL\**\*.cs" Exclude="..\MyProj.Common\Properties\**"> Unfortunately, this adds all the files right to the root of my project... so I end up with a long unreadable list of linked files in the .NET project. I really really really don't want to have to maintain an entire duplicate directory structure by hand and deal with directory name changes and file name changes and whatnot. So, is there any way to have Visual Studio preserve the directory structure when adding linked files in the wildcard manner above? Or is there at least a way of making it group all the linked files together under a directory in the .NET project like MyProj.Common.SL.Links? The very closest I've come is to set the <Visible>false</Visible> under the <Compile> tag, which effectively removes the long unreadable list of 300+ files....but unfortunately this screws up Resharper, which no longer sees those files as valid and it goes crazy on all the projects that reference the .NET project. If I could figure out a way of making Resharper not get all messed up, that would be an acceptable solution too... Any suggestions? Thanks.

  • Can I interrupt javascript code and then continue on a keystroke?

    - by Brian Ramsay
    I am porting an old game from C to Javascript. I have run into an issue with display code where I would like to have the main game code call display methods without having to worry about how those status messages are displayed. In the original code, if the message is too long, the program just waits for the player to toggle through the messages with the spacebar and then continues. This doesn't work in javascript, because while I wait for an event, all of the other program code continues. I had thought to use a callback so that further code can execute when the player hits the designated key, but I can't see how that will be viable with a lot of calls to display.update(msg) scattered throughout the code. Can I architect things differently so the event-based, asynchronous model works, or is there some other solution that would allow me to implement a more traditional event loop? Am I making sense? Example: // this is what the original code does, but obviously doesn't work in Javascript display = { update : function(msg) { // if msg is too long // wait for user input // ok, we've got input, continue } }; // this is more javascript-y... display = { update : function(msg, when_finished) { // show part of the message $(document).addEvent('keydown', function(e) { // display the rest of the message when_finished(); }); } }; // but makes for amazingly nasty game code do_something(param, function() { // in case do_something calls display I have to // provide a callback for everything afterwards // this happens next, but what if do_the_next_thing needs to call display? // I have to wait again do_the_next_thing(param, function() { // now I have to do this again, ad infinitum } }

  • Keyboard causing freezes

    - by fluteflute
    My problem started on Windows XP: a computer (that was working fine for many years) had a problem, that I can't quite remember (may have been to do with the startup process) - but I solved it by swapping the keyboard with one on another machine. Now for several years the problematic keyboard has been working fine - on my main machine that runs Ubuntu. I also dual boot Windows XP - and have had no problems on either OS. However I recently installed Ubuntu 11.04 Natty (pre-alpha) and found that any keyboard press causes freezes. (All still works fine on Ubuntu 10.10 and 10.04 and Windows XP) Just wondering why I might be experiencing this? Seems strange to me that's its not consistent.

  • find word and score based on positions

    hey guys i have a textfile i have divided it into 4 parts. i want to search each part for the words that appear in each part and score that word exmaple welcome to the national basketball finals,the basketball teams here today have come a long way. without much delay lets play basketball. i will want to return national = 1 as it appears only in one part etc am working on determining text context using word position. am working with c# and not very good in text processing basically if a word appears in the 4 sections it scores 4 if a word appears in the 3 sections it scores 3 if a word appears in the 2 sections it scores 2 if a word appears in the 1 section it scores 1 thanks in advance so far i have this var s = "welcome to the national basketball finals,the basketball teams here today have come a long way. without much delay lets play basketball. "; var numberOfParts = 4; var eachPartLength = s.Length / numberOfParts; var parts = new List<string>(); var words = Regex.Split(s, @"\W").Where(w => w.Length > 0); // this splits all words, removes empty strings var wordsIndex = 0; for (int i = 0; i < numberOfParts; i++) { var sb = new StringBuilder(); while (sb.Length < eachPartLength && wordsIndex < words.Count()) { sb.AppendFormat("{0} ", words.ElementAt(wordsIndex)); wordsIndex++; } // here you have the part Response.Write("[{0}]"+ sb); parts.Add(sb.ToString()); var allwords = parts.SelectMany(p => p.Split(' ').Distinct()); var wordsInAllParts = allwords.Where(w => parts.All(p => p.Contains(w))).Distinct();
