• Blackberry Keyboard Lock timeout

  - by Vernon

  I want this blackberry 9700 to "fully lock" as soon as I click the icon for the "Keyboard Lock" application. Currently I have to wait 5 to 7 seconds for the screen to go dark after each time I click the "Keyboard Lock" icon. During that time if something touches the touch pad, then the 5-7 second timer resets and you have to wait another 5 to 7 seconds for the screen to go dark and "fully lock" After it finally goes dark, touching the touch pad does not reset the timer. At that point it is "fully locked" and requires a key to be pressed. How can I get it to "fully lock" as soon as the lock icon is clicked? I want the screen to go dark immediately, and for it to require a key press to request an unlock. I have tried Options - Screen/Keyboard - Backlight Timeout ... etc ... none of that reduces the timeout for the "Keyboard Lock" application. And there does not seem to be an option screen for the "Keyboard Lock" application, that I can find. NOTE: This is occurring with BlackBerry 9700 v5.0.0.330 (Platform 5.1.0.91)

• Building asynchronous cache pattern with JSP

  - by merweirdo

  I have a JSP that will take some 8 minutes to render. The code logic itself can not be made more efficient (it will update often and be updated by basically a pointy haired boss). I tried wrapping it with a caching layer like <%@ taglib uri="/WEB-INF/classes/oscache.tld" prefix="oscache" %> <oscache:cache time="60"> <div class="pagecontent"> ..... my logic </div> </oscache:cache> This is nice until the 60 seconds is over. The next query after that blocks until the 8 minutes of rendering is done with again. I would need a way to build a pattern something like: If there is no version of the dynamic content in the cache run the actual logic (and populate the cache for subsequent requests) If there is a non-expired version of the dynamic content in the cache serve the output of the JSP logic from the cache If there is an expired version of the dynamic content in the cache serve the output of the JSP logic still from the cache AND run the JSP logic in the background so that the cache gets updated transparently to the user - avoiding the user have to wait for 8 minutes I found out that at least EHCache might be able to do some asynchronous cache updating but it did not sadly seem to apply to the JSP tags... Also I have to take in 10-20 parameters for the actual logic of the JSP and some of them should be used as a key for caching. Code example and/or pointers would be greatly appreciated. I do not frankly care if the solution provided is extremely ugly. I just want a simple 5 minute caching with asynchronous cache update taking into account some parameters as a key.

• Unix tool for splitting archives

  - by Richo

  I'm dumping an svn repository to a giant USB disk that is formatted FAT due to necessity (treat this as unchangeable). It conks out when you try to create a file larger than 4 gb. I need a tool that I can pipe data to that will create files of arbitrary size that when catted together will be the original file. I can write a tool to do this, but if one already exists I'd rather use it. Cheers EDIT: A second look at the split man page looks like it might work.

• How to install Windows 8 in a system which has Ubuntu 12.04 and Windows 7 installed already?

  - by Vignesh Palani

  I have a system in which I have installed Windows 7 first. I then installed Ubuntu 12.04 to the system. Now, the boot manager is GRUB Loader and everything works fine as Ubuntu detected that Windows 7 has been installed already. Now, I would like to install Windows 8 too. I plan to install using a bootable USB stick(doesn't matter which medium I prefer though. Does it? ). I have done some research and all the materials I can get state that I cannot practically install Windows 8 after Ubuntu and get all the three OSs to run. Can you help? I want all the three Operating systems to work perfectly.

• Using an ORM with a database that has no defined relationships?

  - by Ahmad

  Consider a database(MSSQL 2005) that consists of 100+ tables which have primary keys defined to a certain degree. There are 'relationships' between tables, however these are not enforced with foreign key constraints. Consider the following simplified example of typical types of tables I am dealing with. The are clear relations between the User and City and Province tables. However, they key issues is the inconsistent data types in the tables and naming conventions. User: UserRowId [int] PK Name [varchar(50)] CityId [smallint] ProvinceRowId [bigint] City: CityRowId [bigint] PK CityDescription [varchar(100)] Province: ProvinceId [int] PK ProvinceDesc [varchar(50)] I am considering a rewrite of the application (in ASP.net MVC) that uses this data source as is similar in design to MVC storefront. However I am going through a proof of concept phase and this is one of the stumbling blocks I have come across. What are my options in terms of ORM choice that can be easily used and why? Should I even be considering an ORM? (The reason I ask this is that most explanations and tutorials all work with relatively cleanly designed existing databases, or newly created ones when compared to mine. I am thus having a very hard time trying to find a way forward with this problem) There is a huge amount of existing SQL queries, would a datamappper(eg IBatis.net) be more suitable since we could easily modify them to work and reuse the investment already made? I have found this question on SO which indicates to me that an ORM can be used - however I get the impression that this a question of mapping? Note: at the moment, the object model is not clearly defined as it was non-existent. The existing system pretty much did almost everything in SQL or consisted of overly complicated, and numerous queries to complete fucntionality. I am pretty much a noob and have zero experience around ORMs and MVC - so this an awesome learning curve I am on.

• How do I catalog files on several external hard drives that I want to store off-line? OSX

  - by raudi

  My partner, an artist, has more than 10 external hardisks both USB and firewire and every 2-3 months a new one has to be added (She's working with videos and pictures) currently its 10TB and growing so too much for a affordable NAS. Right now the files are not indexed and I think can not be searched with spotlight because not all drives can be connected at the same time. So if she wants to search for a file, she has to guess which disk/disks (based mostly on the date) and then search several drives. Now I'm looking for a solution to index/catalog the drives, something like GentibusCD Cathy Disclib (all these solutions are unfortunately Windows only) Is there any software for OSX that will catalog all the hard drives, so she can search the catalog, find the files, and get the ID of the disk / disk name that has the content? Preferably something with a GUI so my partner can also use it easily Preferably with Thumbnails for pictures/videos (But even an equivalent to "tree /F /A" would be better than nothing)

• Dell XPS 710 - Boot Device Not Available

  - by WilliamKF

  Recently I was gifted a Dell XPS 710 tower running WinXP SP3. It was running fine until today when I restarted and received a blue screen and the error "unmountable boot volume". In order to fix this issue I've attempted to boot from the Windows XP CD and run chkdsk. However when I attempt to boot from the CD drive I get a "Boot Device not Available" error. Next I made a bootable USB flash drive, but receive the same error as the CD drive. The BIOS recognizes the CD and flash drives, and they appear in the boot device list, but neither will boot. I've attempted to resolve this by re-arranging the boot order in the BIOS and switching IDE channels/setting jumpers on the drives themselves, to no effect. I cannot move the hard drive to another machine because the XPS is the only one that supports SATA drives.

• Ubuntu server: lost prompt on monitor

  - by Richard

  Hello All, I am running Ubuntu 9.04 server edition. I have a monitor plugged into the box for occasional admin tasks.

Doesn't appear to be registering keyboard strokes. The box is still running fine (I can ssh in from elsewhere and evrything is running as normal). Any ideas on how to clear screen and get my prompt back?

• How do I share a home printer under Windows if the computer is part of a domain?

  - by Sorin Sbarnea

  I do have my work laptop at home and I want to share an USB printer in order to be able to print to it from my MacBook. Currently Windows 7 is refusing to share the printer because the computer is part of a domain and it tells me that I need to join a homegroup in order to be able to do that. Also it tells me that he cannot create this homegroup and this group has to be create by another Windows 7 computer from my network. As you can imagine I do have only one Windows computer on my home network. How can I solve this problem?

• Is there a tool for managing redundant pages across a website?

  - by dmanexe

  I am in charge of constructing a website with a '2-dimensional' site map, as explained later. I am looking for (preferably a Wordpress plugin, as the site is built in Wordpress already) that would make managing thousands of pages a lot easier. To explain further, let me iterate my situation. I am building a website for a construction company, and they have several key cities and several key services. Now, they want a parent page for each service, and another unique page for the child sub-service, and finaly, a grandchild page for the city they are performing the service in. For example, if they were doing Concrete Construction in Los Angeles, the URL would look like: /concrete/construction/los-angeles The content on /los-angeles would be the same as on /malibu, or /burbank. However, there would be a different set of content for /concrete/design/los-angeles, but the entire page content (sans a few variables with city names) would be the same. Is there a way to manage or automate 'matrixing' this information on the site? I am looking for a tool that would allow me to easily add a 'city' with the same content across all grandchildren, per the child's content requirements. All of the grandchildren pages will have redundant content across them. Should something like this not exist, how difficult would it be to create, as a freelance side project? I need a tool like this, because I am approaching about ~500 cities and 50 services (Concrete Construction, Concrete Design, Concrete Engineering, etc)

• Asus WL-520GC + external HDD via Ethernet

  - by Azat

  Has anyone experience of using such combination? Exactly with the same model (or from same model line). How does it works? How hard is to set up all that? What difficulties? I use this router a couple of years, but now i haven't such external drive at my disposal. I want to buy something like Verbatim 47591 or Western Digital WDH1NC10000. (By the way, my router has no USB ports, therefore only Ethernet-ports for external HDD are supported.) Thanks you a lot in advance!

• Hibernate saveorUpdate method problem

  - by umesh awasthi

  Hi all, i am trying to work on with Hibernate (Database side for first time) and some how struck in choosing best possible way to use saveOrUpdate or Save.Update i have a destination POJO class and its other attributes which needs to be updated along with the Destination entity. i am getting an XML file to be imported and i am using the following code to update/save the destination entity along with its attribute classes. try{ getSessionFactory().getCurrentSession().beginTransaction(); getSessionFactory().getCurrentSession().saveOrUpdate(entity); getSessionFactory().getCurrentSession().getTransaction().commit(); } catch(Exception e){ getSessionFactory().getCurrentSession().getTransaction().rollback(); } finally{ getSessionFactory().close(); } everything is working fine untill i am using the same session instance.but later on when i am using the same XML file to update the destination PO for certain attributes it giving me the following error. SEVERE: Duplicate entry 'MNLI' for key 'DESTINATIONID' 9 Jan, 2011 4:58:11 PM org.hibernate.event.def.AbstractFlushingEventListener performExecutions SEVERE: Could not synchronize database state with session org.hibernate.exception.ConstraintViolationException: Could not execute JDBC batch update at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:94) at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:66) at org.hibernate.jdbc.AbstractBatcher.executeBatch(AbstractBatcher.java:275) at org.hibernate.jdbc.AbstractBatcher.prepareStatement(AbstractBatcher.java:114) at org.hibernate.jdbc.AbstractBatcher.prepareStatement(AbstractBatcher.java:109) at org.hibernate.jdbc.AbstractBatcher.prepareBatchStatement(AbstractBatcher.java:244) at org.hibernate.persister.entity.AbstractEntityPersister.insert(AbstractEntityPersister.java:2242) at org.hibernate.persister.entity.AbstractEntityPersister.insert(AbstractEntityPersister.java:2678) at org.hibernate.action.EntityInsertAction.execute(EntityInsertAction.java:79) i am using UUID as primary key for the Destination table and in destination table i have a destination id which is unique.but i can understand that in the secodn case hibernate is not able to find if there is already an entry for the same destination in the DB and trying to execute insert statement rather than update. one possible solution is i can user destinationid to check if there is already a destination inplace with the given id and based on the results i can issue save or update command. my question is can this be achieve by any other good way..? Thanks in advance

• Insert data in an object to a database.

  - by paul

  I am facing the following design/implementation dilemma. I have a class Customer which is below with getters and setters. I would like to insert the value of the Customer into a "Customer" table of a database. But Customer has an address which is of type "Address". How do I go about inserting this field into the database?(I am using sqlite3). I thought of writing a separate table "Address(customerId,doorNo,city,state,country,pinCode)". But I am having second thoughts about generating the primary key(customerId) which should be same for both the "customer" and "Address" table. Sqlite3 faq states that I can do "Integer Primary Key" to use the field to generate an auto number. But if I do that in customer table, I would have to retrieve the same Id to be used in Address table. This kinda looks wrong to me :-?. There should be an elegant method to solve this. Any ideas would be much appreciated. Thanks in advance. import java.io.*; import java.sql.*; class Customer { private String id; private String name; private Address address; private Connection connection; private ResultSet resultSet; private PreparedStatement preparedStatement; public void insertToDatabase(){ } } class Address{ private String doorNumber; private String streetName; private String cityName; private String districtName; private String stateName; private String countryName; private long pinCode; }

• RSKeyMgmt -r unable to remove installtion ID

  - by Eves

  I have backed up databases on one 2005 SQL Server and have restored those databases on a second 2005 SQL Server. I am currently trying to remove the new server's OLD key instance ID using the Reporting Services Key Manager (RSKeyMgmt -r). Prior to running the removal command the list of the current instances shows the new server's OLD instance ID as well as the NEW instance ID from the first SQL Server. Executing the RSKeyMgmt -r command results in: "The command completed successfully". However, when I recheck the listing of current instance IDs I see both the OLD and NEW instance IDs. In addition, when I check the Application Event Viewer I see an error: Report Server Windows Service (MSSQLSERVER) has not been granted access to the catalog content Does anyone know why I would be getting the above application error? Or...does anyone know what I would need to do to give access to the catalog to the Report Server Window Service? The first SQL Server where the databases were backed up is an Enterprise edition SQL Server and the second SQL Server where the databases were restored is Standard edition. Could this be the cause of the problem? Is there a way to make this backup and restore migration work?

• Delay before booting with laptop

  - by Priednis

  I have almost the same problem as in Delay before booting? My computer is a practically new (couple months) Lenovo X200 Tablet (System Model 7449FXG). So when I press the power button, the indicator light that means "computer is on" turns on, but nothing else happens for about 5 mins, after that the computer starts booting normally. The same happens also on restart. And no USB or any other device for that matter is plugged in to the computer. And at the delay time the monitor is blank - actually not on at all.

• What tool can I use to definitely kill a process on Windows?

  - by Moak

  Can anyone recommend an application (preferably usb-portable that doesn't require setup) That really kills a process immediately in windows XP? I ask this because often when I need to use the XP task manager it seems to want to go about it "the polite way" and sometimes crashed programs don't quit or take a minute to shut down. I need a real stone cold killer, not a pushover-could-you-please-quit-now-no?-ok-sorry-program Edit I'm sorry if it wasn't clear previously but I did mean the situation when even the "End process" command in Process tab of the task manager doesn't kill a program, however one of the answers did point me to the "End Process Tree" command which I've never noticed (when right clicking on the process)

• WPF ContextMenu bind some property to another property of the same control

  - by bebicasoft

  I have a ContextMenu and a ColumnHeaderStyle defined in Window.Resource section witch i use-it to a DataGrid ColumnHeader. My code is something like this: <ContextMenu x:Key="cm_columnHeaderMenu"/> <Style x:Key="DefaultColumnHeaderStyle" TargetType="{x:Type DataGridColumnHeader}"> <Setter Property="ContextMenu" Value="{StaticResource cm_columnHeaderMenu}" /> </Style> <DataGrid Grid.Column="2" Grid.Row="1" x:Name="dgridFiles" IsReadOnly="True" ColumnHeaderStyle="{StaticResource DefaultColumnHeaderStyle}"> I want to know if I can (and if the answer it true, then HOW I could do it) bind the ContextMenu Visibility property to same control ContextMenu Items.Count>0 property. Initially based on some other treeView control selections made there shoud be no items in the context menu, but i wish to add dinamically items in ContextMenu based on selection in treeView. This part is done, the context has those items. On some selections there are no-items, but still on the grid it appears an empty ContextMenu. So I believe the easiest part it would be to bind the Visibility to Items.Count property of the same control. Sorry if my english is not good enought, I'll try to explain better if i didnt make clear 1st time.

• Too Many Files In Debian Linux Folder?

  - by Dave Potts

  I've been using an external USB drive on a Debian server for backup. The drive is formatted as NTFS and mounted with ntsfmount. This was working fine, but I was filling up a directory with lots of files. Eventually the backup failed. When I then tried to look at the directory using ls it reported: ls: reading directory .: Numerical result out of range Looking in syslog, I also saw this: Sep 23 07:35:31 tosh ntfsmount[28040]: Failed to read index block: Numerical result out of range. Is this simply that I've reached the upper limit of number of files in a directory? If so, is there any way to extend the number of allowed files?

• Transferring analog media (VHS casettes, vinyl records) to PC

  - by Javier Badia

  I have some VHSs and vinyl records which I'd like to convert to DVDs and CDs, respectively. I have a couple of questions about how to hook the devices up to the computer. I've seen some RCA-to-USB cables on the Internet like this one. Will those work for connecting the VCR to the computer? And what program would I use to take that and save it as a video file? Can I connect the phonograph directly to the Line In port in my PC or do I need some amplifier or something in the middle? I'm using Windows 7 x64, if it matters.

• function returns after an XMLHttpRequest

  - by ashays

  Alright, I know questions like this have probably been asked dozens of times, but I can't seem to find a working solution for my project. Recently, while using jQuery for a lot of AJAX calls, I've found myself in a form of callback hell. Whether or not jQuery is too powerful for this project is beyond the scope of this question. So basically here's some code that shows what's going on: function check_form(table) { var file = "/models/"+table+".json"; var errs = {}; var xhr = $.getJSON(file, function(json) { for (key in json) { var k = key; var r = json[k]; $.extend(errs, check_item("#"+k,r)); } }); return errs; } And... as you can probably guess, I get an empty object returned. My original idea was to use some sort of onReadyStateChange idea that would return whenever the readyState had finally hit 4. This causes my application to hang indefinitely, though. I need these errors to decide whether or not the form is allowed to submit or not (as well as to tell the user where the errors are in the application. Any ideas? Edit. It's not the prettiest solution, but I've managed to get it to work. Basically, check_form has the json passed to it from another function, instead of loading it. I was already loading it there, too, so it's probably best that I don't continue to load the same file over and over again anyways. I was just worried about overloading memory. These files aren't absolutely huge, though, so I guess it's probably okay.

• modprobe ndiswrapper - not found

  - by David

  I'm trying to use ndiswrapper on a Slackware 12 (I think) box, but I'm running into a problem with modprobe. Everything I find online says that it should be working, but for some unknown reason it isn't. Here's what I've done so far: Installed ndiswrapper (latest tarball, make, make install) Ran ndiswrapper -i on the WinXP driver for my USB wireless card Ran ndiswrapper -l which tells me the driver is present and the device is present (lsusb also confirms the device is present) Ran ndiswrapper -m which put an alias for wlan0 in /etc/modprobe.d/ndiswrapper.conf Ran depmod -a Ran modprobe ndiswrapper which tells me "FATAL: module ndiswrapper not found" Ran modprobe -l which shows no listing for ndiswrapper I even tossed in a reboot or two while trying various combinations of the above, still nothing. So naturally ifconfig wlan0 up isn't working because the device isn't being created, presumably because the module isn't loading the driver. Does anybody have any suggestions? Everything points to the notion that this should work fine, but modprobe just isn't able to find what it needs. Have I missed an important step?

• SSH with Perl using file handles, not Net::SSH

  - by jorge

  Before I ask the question: I can not use cpan module Net::SSH, I want to but can not, no amount of begging will change this fact I need to be able to open an SSH connection, keep it open, and read from it's stdout and write to its stdin. My approach thus far has been to open it in a pipe, but I have not been able to advance past this, it dies straight away. That's what I have in mind, I understand this causes a fork to occur. I've written code accordingly for this fork (or so I think). Below is a skeleton of what I want, I just need the system to work. #!/usr/bin/perl use warnings; $| = 1; $pid = open (SSH,"| ssh user\@host"); if(defined($pid)){ if(!$pid){ #child while(<>){ print; } }else{ select SSH; $| = 1; select STDIN; #parent while(<>){ print SSH $_; while(<SSH>){ print; } } close(SSH); } } I know, from what it looks like, I'm trying to recreate "system('ssh user@host')," that is not my end goal, but knowing how to do that would bring me much closer to the end goal. Basically, I need a file handle to an open ssh connection where I can read from it the output and write to it input (not necessarily straight from my program's STDIN, anything I want, variables, yada yada) This includes password input. I know about key pairs, part of the end goal involves making key pairs, but the connection needs to happen regardless of their existence, and if they do not exist it's part of my plan to make them exist.
