• USB printer doesn't finish in 12.04

  - by 213441265152351

  I have an HP Deskjet 720C connected through a USB cable to an Ubuntu 12.04 laptop. When I plugged the printer for the first time into the fresh 12.04 laptop install, it auto-detected the printer correctly and choose the recommended drivers without a problem. The document print fine until they reach the end of the page, then suddenly stop just about the end leaving the page unfinished. I have checked that the margins are the correct ones. I have the latest version of cups installed. I have also tried changing the options of usb-unidir-default and usb-no-reattach-default via lpadmin, but the printing stops even earlier. Any ideas?

• No sound in any web browser(s)

  - by shaneo

  Hello I recently tried to compile and update alsa from source via this guide http://www.stchman.com/alsa_update.html. Afterwards the sound in any web browser I open Firefox, Opera, Chrome, Chromium, Iron there is no sound on any pages. I went back through the script listed on the site and found where it had installed the drivers and deleted it and than re-installed alsa via synaptic. Though I still have no sound in my browser(s). All system sounds work as they are supposed to only web sounds don't work. Here is my alsabase.conf http://paste.ubuntu.com/1073135/ also a snapshot of alsamixer Any assistance would be greatly appreciated. Thank You and let me know if any more information is required.

  I have installed Vmware Player 6.0.3 build-1895310. The problem I have is that when I run a Windows 7 Vm, it says that 3D support was disabled. (I can't read the exact report atm because it has a chance of crashing my machine.) I have the 3D support box enabled. Here is my graphics card: Mobile Intel® GM45 Express Chipset x86/MMX/SSE2. Can anyone tell me to install drivers or something? I can't find mine anywhere!

• mysql replace matching but not changing

  - by alex

  I've used mysql's update replace function before, but even though I think I'm following the same syntax, I can't get this to work-it matches the rows, but doesn't replace. Here's what I'm trying to do: mysql> update contained_widgets set preference_values = replace(preference_values, '<li><a_href="/enewsletter"><span class="not-tc">eNewsletter</span></a></li>', '<li><a_href="/enewsletter"><span class="not-tc">eNewsletter</span></a></li> <li> <a_href="/projects"><span class="not-tc">Projects</span></a></li>'); Query OK, 0 rows affected (0.00 sec) Rows matched: 77 Changed: 0 Warnings: 0 I don't see what I'm missing. Any help is appreciated. I edited "a " to "a_" because the site thinks I'm posting spam links otherwise.

• The Dreaded Startup Repair Loop on Win 7

  - by HighAltitudeCoder

  For most people, upgrading to Windows 7 has been a relatively painless process.  Not me.  I am in the unlucky 1% or less who had a somewhat less pleasant experience.  First, I cloned my entire onto a larger (and much faster) solid state hard drive, only experiencing minimal problems. Then, I bought the Retail version of Windows 7 Ultimate, took a deep breath and... oh yeah, I almost forgot - BACK UP THE COMPUTER.  The next morning I upgraded to Win 7 and everything seemed fine, until... I rebooted the system, the nice Windows 7 launch graphics come up, it's about to launch and AWWW, are you kidding me?!?!  Back to the BIOS splash screen?  Next comes the sequence of failure - attempt repair - unable to repair - do you want to wipe your hard drive decisions. Because I purchased the retail version, a number is provided where I could call Microsoft Tech support.  When I did, they instructed me to click "Install" from my installation CD, which did not work.  When I tried the "Upgrade" option, it reaches an impasse, telling you that yoiu have a newer version of Win 7, and thus cannot Upgrade.  If you choose "Install" you willl lose everything... files, programs, EVERYTHING.  Or at least this is what it tells you.  I was not willing to take the risk. To make things worse, I had installed a new antivirus software application before I realized my system was unstable (Trend Micro Titanium Internet Security), and this was causing additional problems. One interesting thing, and the only saving grace as it turns out, was that my system WOULD successfully reboot into the OS if I chose to restart it, rather than shut it down.  If I chose to shut down, I would have to go through the loop again until I was given the option to restart. As it turned out, I needed to update my BIOS.  I assumed that since I had updated my BIOS a long time ago to settings that were stable under Windows Vista Ultimate x64, I incorrectly expected Win 7 to adopt the same settings and didn't expect there to be any problems.  WRONG. My BIOS had a setting to halt the boot cycle if various kinds of errors were detected.  Windows Vista didn't care about this, but forget it under Windows 7.  I turned immediately corrected that BIOS setting.  Next, there were the two separate BIOS settings: enable USB mouse and enable USB keyboard.  The only sequence of events that would work were to start my reboot process over from stratch with a hard-wired non-usb keyboard and mouse.  Whent the system booted under these settings, it doesn't detect any errors due to either the mouse or keyboard, and actually booted for the first time in a long while (let me tell ya, that's an amazing experience after fiddling with settings for two entire weekends!) Next step: leave your old mouse and keyboard connected, but also connect your other two devices (mouse, keyboard) that use USB connections.  During the boot cycle, the operating system will not fail due to missing requirements during startup, and it will then pick up the new drivers necessary to use your new hardware. If you think you are in the clear here, you are wrong.  The next VERY IMPORTANT step is to remember to change your settings in the BIOS upon next startup.  Specifically, yoiu will need ot change your BIOS to enable USB mouse and enable USB keyboard input.  If you don't, Windows will detect an incompatibility upon the next startup, and you will be stuck once again in the endless cycle of reboot/Startup Repair/reboot/Startup Repair, without ever reaching a successful boot. Here's the thing - the BIOS and the drivers registered in Win 7 need to match.  If they don't, you're going to lose another weekend worrying and fiddling, all the while wondering if you've permanently damaged your hard drive beyond repair. (Sigh).  In the end, things worked out.  I must note that it is saddening to see how many posts there are out there that recommend just doing a clean install, as if it's the only option.  How many countless poor souls have lost their data, their backups, their pictures and videos, all for nothing other than the fact that the person giving advice just didn't know what to do at that point? My advice to you, try having a look at your BIOS settings first and making sure Win 7 can find your BIOS settings, and also disabling in your BIOS anything that might halt your system boot-up process if it encounters errors.

• Paperclip + ImageMagick on Windows 7: Image display fails when I add styles to attached_file in mode

  - by Brian Roisentul

  I'm working with Ruby on rails 2.3.8, NetBeans IDE. I've installed paperclip and I could show/save images successfully. Now, I've installed ImageMagick-6.6.2-4-Q16(for windows 7, 64bits). Until that moment, my model looked like this(and worked fine): has_attached_file :photo Now, after installing ImageMagick, when I add the :style line it fails: has_attached_file :photo, :styles => {:thumb => "100x100#", :small => "150x150>", :large => "400x400>" } and it throws the following error message when I try to upload an image: TypeError in ProfilesController#update backtrace must be Array of String The only thing I'm doing in the update action of that controller is the following: @profile.update_attributes(params[:profile]) @profile.update_attribute(:photo, params[:profile][:photo]) I've also installed miniMagick gem(because I read somewhere I had to do it). What am I missing?

• ASP.Net WebSite Membership AND C# Windows Form Membership

  - by user1638362

  This is not real, it's just a project i'm working on I've created a Hotel Management system in C# WindowsForm, it allows staff members to Add/Edit/Update Rooms,Reservation and Customers etc. Along side this Windows-form i'm creating an ASP.net WebSite where customers should be able to register and reserve rooms online. I've come to the point where i need to create some-type of membership method for this website which should correspond to the membership of the windows form. However i'm not sure what method of membership would be best suited for this, i have looked into the asp.net membership, it's what i want however it creates it's own schema and i don't know how i can relate the information to my customers table and c#windows form. I would ideally like it to resemble a real-life situation as much as possible anyway, am i going about this the wrong way? in terms of the c# windows-form what other technology would a business use to manage a system like this where they can add/edit/update there system and have a website which relates. What are my options here?

• EXC_MEMORY_ACCESS when trying to delete from Core Data ($cash solution)

  - by llloydxmas

  I have an application that downloads an xml file, parses the file, and creates core data objects while doing so. In the parse code I have a function called 'emptydatacontext' that removes all items from Core Data before creating replacements items from the xml data. This method looks like this: -(void) emptyDataContext { NSFetchRequest * allCon = [[NSFetchRequest alloc] init]; [allCon setEntity:[NSEntityDescription entityForName:@"Condition" inManagedObjectContext:managedObjectContext]]; NSError * error = nil; NSArray * conditions = [managedObjectContext executeFetchRequest:allCon error:&error]; DebugLog(@"ERROR: %@",error); DebugLog(@"RETRIEVED: %@", conditions); [allCon release]; for (NSManagedObject * condition in conditions) { [managedObjectContext deleteObject:condition]; } // Update the data model effectivly removing the objects we removed above. //NSError *error; if (![managedObjectContext save:&error]) { DebugLog(@"%@", [error domain]); } } The first time this runs it deletes all objects and functions as it should - creating new objects from the xml file. I created a 'update' button that starts the exact same process of retrieving the file the proceeding with the parse & build. All is well until its time to delete the core data objects. This 'deleteObject' call creates a "EXC_BAD_ACCESS" error each time. This only happens on the second time through. Captured errors return null. If I log the 'conditions' array I get a list of NSManagedObjects on the first run. On the second this log request causes a crash exactly as the deleteObject call does. I have a feeling it is something very simple I'm missing or not doing correctly to cause this behavior. The data works great on my tableviews - its only when trying to update I get the crashes. I have spent days & days on this trying numerous alternative methods. Whats left of my hair is falling out. I'd be willing to ante up some cash for anyone willing to look at my code and see what I'm doing wrong. Just need to get past this hurdle. Thanks in advance for the help!

• SVN - When you tag a working copy is it still a cheap copy?

  - by mcdon

  Using Subversion, in my working copy I make a minor modification (update a version number). I would then like to tag my working copy. Would this tag still be a cheap copy with the modification, or would SVN duplicate the files? I would hate to see my repository grow enormously in size because I'm trying to save a version number change. The reason I ask about creating a tag that contains a modification rather than committing then tagging involves my build server. The build server creates a CCNetLabel which I use to update the version numbers of my projects (AssemblyInfo.cs). When the build is successful it creates a tag. When I use ForceBuild the tag is based on the working copy which would contain the modified version number. I want the tag to contain the appropriate version number. note: It's debatable if I'm creating a branch or a tag, however SVN does not make a distinction between the two.

• Pass information to php file from javascript while restricting user from doing it their self?

  - by Sean Madigan

  I am making a game where the battle system uses javascript to battle. At the end of the battle you either win or lose. If the user wins, I need to update the mysql database with the XP they earned. The best way I can think of doing this is to have the javascript run an ajax function when the user wins that POSTs something like addxp.php?amount=235, but if I do that then the user can easilly look at the source and see that they can just enter in that page themself to update their xp without battling. But this is the only way I know how to do it? Help please :-/

• JqueryUI serialize data not working on first record

  - by peace

  I am using jqueryUI v1.8. I have created a modal dialog form to edit records of a table. When the edit link on the record is clicked the record data is displayed on the form and the user edits the record. When the user submits this form the data is serialized and posted via ajax to update the database. This works well with all records except the first one. Nothing is posted to server for update only for the first record. alert(serializeddata); is empty. Similarly, The first form element in every record chosen for editing does not show the actual value the first time. Once you cancel editing and close the dialog and reopen you can see the fields accurate data. How do I resolve this?

• Scala case class generated field value

  - by Petteri Hietavirta

  I have an existing Scala application and it uses case classes which are then persisted in MongoDB. I need to introduce a new field to a case class but the value of it is derived from existing field. For example, there is phone number and I want to add normalised phone number while keeping the original phone number. I'll update the existing records in MongoDB but I would need to add this normalisation feature to existing save and update code. So, is there any nice shortcut in Scala to add a "hook" to a certain field of a case class? For example, in Java one could modify setter of the phone number.

• If I enable/disable my wireless device, my computer will panic

  - by Yinyanghu

  Now, I use Debian 6.0.6 instead of Fedora 16/17. But I still sustain the problem of my wireless problem. If I enable/disable my laptop wireless device or my usb wifi adaptor, my laptop will panic. It seems like all the processes stop at that time and I have to restart my laptop directly. P.S. I think I installed the drivers correctly and the linux kernel may have some bugs. For example, when I unplug my usb wifi adaptor or I use this command, ifdown wlan0 I encounter this problem. Wireless Device: PCI: 03:00.0 Network controller: Broadcom Corporation BCM43225 802.11b/g/n (rev 01) USB: Bus 002 Device 005: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN

• Wireless not functional

  - by Michael Berkenblit

  I am a complete newcomer to Ubuntu. Today I installed Ubuntu 12.04 onto an 3 or 4 year old laptop - an HP DV2221. Install went fine, except that I can't get the wireless card to operate. I see that there are drivers installed (Broadcom STA wireless) and it says they are activated, but the wireless light on the body of the computer is lit as orange, when it should be blue, and if I disconnect the Ethernet wire, there is no ability to get onto Firefox. I've looked at some of the similar questions on this site, as well as Googling the issue - mostly, I guess I don't understand how to navigate or do some of the fixes recommended - I'm fairly adept technologically around Windows, but know zilch about Linux and how to perform some of the fixes - so, if possible, please tell me how I get to the menus needed to rectify the situation.

• Dynamically changing validations in Rails

  - by user94154

  I have a model with a validation. At runtime, I'd like to change a value of the validation. For example: in the model bid.rb: class Bid ActiveRecord::Base @foo = Foo.find(1) validates_inclusion_of :amt, :in => [email protected], :message => "must be between 1 and #{@foo.bar}" end and in the application_controller (pseudocode): if today == 'wednesday' Foo.update(1, :bar => 10) else Foo.update(1, :bar => 5) end However, this setup isn't working. The "foo" attribute never updates. It seems that the validation code is set only when the dev server starts and then doesn't change.

• MYSQL - How to increment fields in one row with values from another row

  - by Walker Boh

  I have a table that we'll call 'Sales' with 4 rows: uid, date, count and amount. I want to increment the count and amount values for one row with the count/amount values from a different row in that table. Example: UID | Date | Count | Amount| 1 | 2013-06-20 | 1 | 500 | 2 | 2013-06-24 | 2 | 1000 | Ideal results would be uid 2's count/amount values being incremented by uid 1's values: UID | Date | Count | Amount| 1 | 2013-06-20 | 1 | 500 | 2 | 2013-06-24 | 3 | 1500 | Please note that my company's database is an older version of MYSQL (3.something) so subqueries are not possible. I am curious to know if this is possible outside of doing an "update sales set count = count + 1" and likewise for the amount columns. I have a lot of rows to update and incrementing the values individually is quite time consuming if you can imagine. Thanks for any help or suggestions!

It's very discouraging because it might force me to go back to Windows which I hate. Can someone help? Perhaps I can give you some information to help identify what the issue is? b43 isn't coming up in my list of drivers...just Broadcom STA which doesn't work. I think I've removed all the blacklisted stuff... Thanks in advance! Annie

• How to get min/max of two integers in Postgres/SQL?

  - by HRJ

  How do I find the maximum (or minimum) of two integers in Postgres/SQL? One of the integers is not a column value. I will give an example scenario: I would like to subtract an integer from a column (in all rows), but the result should not be less than zero. So, to begin with, I have: UPDATE my_table SET my_column = my_column - 10; But this can make some of the values negative. What I would like (in pseudo code) is: UPDATE my_table SET my_column = MAXIMUM(my_column - 10, 0);
