  • Accidentally hit shortcut and lost text in web browser. Can it be disabled?

    - by uniomni
    I have noticed that I occasionally hit some shortcut while typing that either kills the browser or otherwise causes me to lose e.g. a post I am writing. This typically happens if I type while on a bumpy road or something like that. It also just happened to my eight year old daughter ;-( I think the shortcut in question is CTRL-w which (at least in Firefox) closes the current tab and consequently whatever content is being written. I would like to know if anyone has noticed this and if someone has a solution e.g. a way to disable "dangerous" shortcuts if at all possible. Many thanks Ole (uniomni)

  • How can I combine non-identical disks efficiently?

    - by Odys
    There are some not-identical disk of various capacities that I want to combine (somehow). Since there are no duplicate models, I can't use raid between none of them. Is there a way to use them efficiently while being safe? What I have in mind is a software that will use them as if it were Raid-5 or something. I really don't care about max speed. I want in the end to have as less logical drives as possible. Also, I don't mind spending some money on hardware, if needed.

  • Multiple database accesses or one massive access?

    - by DudeOnRock
    What is a better approach when it comes to performance and optimal resource utilization: accessing a database multiple times through AJAX to only get the exact information needed when it is needed, or performing one access to retrieve an object that holds all information that might be needed, with a high probability that not all is actually needed? I know how to benchmark the actual queries, but I don't know how to test what is best when it comes to database performance when thousands of users are accessing the database simultaneously and how connection pooling comes into play.

  • SEO - different data with same title and keywords

    - by Junaid Saeed
    here is my scenario i have a website where i redirect my users basing upon the device they were using, lets say a user is visiting from an iPad, i take him directly to the page of iPad wallpapers, the user selects iPad version & i take the user to the gallery of wallpapers where the user can select & download any wallpaper. Every wallpaper is the required resolution, i have my reasons for doing this, now the thing is there are diff. resolution. versions of an image appearing one 5 diff. sections of my website, each having their own view page Now there is only one record in db.table for the image, and basing on the my consistent naming convention of the images, i pick the required image. this means when 5 different pages are generated in 5 categorized sections of the website, due to a shared DB record, the keywords, the titles and every single detail of the 5 pages is same besides the resolution of the image, and the section specific details that the page has and yeah the pages also have different paths like wallpapers.com\ipad-1\cars\Ferrari-dino.html wallpapers.com\ipad-2\cars\Ferrari-dino.html wallpapers.com\ipad-3\cars\Ferrari-dino.html wallpapers.com\ipad-4\cars\Ferrari-dino.html wallpapers.com\ipad-5\cars\Ferrari-dino.html now this is my scenario, How do Search Engines see it and how do they rank it? Is it a Good or Normal or Bad SEO practice? If bad how dangerous it is for my sites SEO? i need your comments on my scenario.

  • My 4 GB microSD card only allows me to use 1 GB

    - by James Litewski
    My phone came with a 4 GB microSD card. On the card it lists that 3 GB goes to Muve Music which is Cricket's music program, and I get 1 GB... Well, I don't pay for Muve Music, so why waste the space? I thought I'd be able to simply buy an adapter and reformat the microSD card to get the full 4 GB; but that wasn't the case... I could only find the 1 GB partition on the card. I even tried reformatting the disk, but I had no luck. How can I get the full 4 GB? BTW, I'm running Mac OS X v10.7 (Lion).

  • Data Mining Email with Thunderbird

    - by user554629
    Oracle has many formal, searchable locations:  Service Requests, BugIDs, Technical Documents. These contain the results of an investigation for a customer crash situation;  they're created after the intense work of resolution is over, and typically contain the "root cause" of the failure ... but not the methods for identifying that cause. Email is still the standby for interacting with quickly formed groups of specialists, focusing on a particular incident.Customer BI, Network and System specialists;  Oracle Tech Support, Development, Consultants; OEM Database, OS technical support.   It is a chaotic, time-oriented set of configuration, call stacks, changes, techniques to discover and repair the failure. I needed to organize that information into something cohesive to prepare the blog entry on Teradata.  My corporate email client of choice is Thunderbird.   My original (flawed) search technique: R-Click on Inbox in Thunderbird left pane, and choose Search Messages Subject:  [ teradata ] Results: A new window titled "Search Messages"Single pane of selected messagesColumn headings:  Subject  From  Date  LocationNo preview window for messages There are 673 email entries in the result ( too many )  R-click icon just above the vertical scroll bar on the rightCheck [x] Tags Click on the Tags header to sort by "Important" View contents of message by double-clickingOpens in the Thunderbird Main Window in a new Tab Not what I was looking for, close the tab and try again. There has to be a better way.  ( and there is ) I need to be more productive, eliminating duplicate-chained messages, for example.   Even the Tag "Important" that was added during the investigation phase, is "not so much" for my current task. In the "Search Messages" window, click [ Save as Search Folder ] [ teradata ]  Appears as a new folder in my Inbox. Focus on that folder and the results appear with a list of messages like every other folder in the Inbox.Only the results of the search are shown A preview window is now available for each message Sort, Select message, Cursor Down ... navigates quickly through the messages. But wait, there's more ... Click Find ( Ctrl-F) Enter a search term for the message body, like.[ LIBPATH ] The search is "sticky" ... each message you cycle through wil focus ( and highlight) the LIBPATH search term. And still more .... Reset the Tag"Important" message.   Press "1" and the tag is removed Press "4" and a new Tag "ToDo" is applied After applying all of the tags, sort by Tag for a new message order Adjust the search criteria ... R-click on the [ teradata ] search folder, and choose Properties Add additional criteria to narrow the search Some of the information I'm looking for did not contain "teradata" in the subject line. + Body  [ contains ] [ Best Practices ] That's it.  Much more efficient search.   Thank you Thunderbird.

  • Best way to update UI when dealing with data synchronization

    - by developerdoug
    I'm working on a bug at work. The app is written in Objective-C for iOS based device, for the iPad. I'm the new guy there and I've been given a hard task. Sometimes, the UIButton text property does not show the correct state when syncing. Basically, when the app is syncing, my UI control would say "Syncing" and when its not syncing it'll display "Updated @ [specific date]". Right now there is a property on the app delegate called "SyncInProgress". When querying / syncing, occurring on background thread, it updates a counter. The property will return a bool checking expression 'counter 0'. There are three states I need to deal with. Sync has started. Sync is updating tables. Sync finished. These items need to occur in order. My coworker suggested to take a state based approach instead of just responding to events. I'm not sure about how to go about that. Would it be best to have the UI receive a notification to determine what state its in or to pull every so often if state changed? Here are two posts that I put on stackoverflow, in the last few days, that relate to this. http://stackoverflow.com/questions/11025469/ios-syncing-using-a-state-approach-instead-of-just-reacting-to-events http://stackoverflow.com/questions/11037930/viewcontroller-when-viewwillappear-called-does-not-always-correctly-reflect-stat Any ideas that anyone might have to very much appreciated. Thanks, developerDoug

  • Would hybrid drive work after SSD failure

    - by lulalala
    Hybrid hard drive combines SSD with traditional hard drives. I know that SSD can fail much often than traditional hard drives. So I want to ask that, when the SSD part of the hybrid drive fails, would I still be able to use the traditional hard drive? If it won't work like that, then I will consider add-in SATA cards instead, as it delegates risk much better. EDIT: I guess it differs from model to model, so if yes what models would work. (I am evaluating Seagate DX for now)

  • Deleting a game object causing an access violation

    - by Balls
    I tried doing this but it cause an access violation. void GameObjectFactory::Update() { for( std::list<GameObject*>::iterator it=gameObjectList.begin() ..... (*it)->Update(); } void Bomb::Update() { if( time == 2.0f ) { gameObjectFactory->Remove( this ); } } void GameObjectFactory::Remove( ... ) { gameObjectList.remove( ... ); } My thoughts would be to mark the object to be dead then let the factory handle it the on next frame for deletion. Is it the best and fastest way? What do you think?

  • Recommendations for stable, reliable flash drives

    - by Josh Kelley
    We're looking to purchase some flash drives for use in some embedded devices. Most of our requirements aren't too different the generic "good, fast" flash drive: reliability is very important, speed is good, and so that the drive will fit, the case shouldn't be too large (so no OCZ Throttles). Consistency is also a major priority; we'd like to be able to buy more or less the same product a year or two from now without having to worry about the manufacturer swapping drive components with less reliable or slower parts. (We've been burned already by our previous manufacturer doing this.) Any recommendations, especially regarding consistency? I can read Ars Technica to get an overview of current models, but what are consistently good models?

  • Advice for migrating email server

    - by Chris Adams
    Hi there, I'm planning to migrate a Zimbra server with about 200gb of data from a server hosted in an office into a datacentre, to increase uptime (we've had a couple of outages when our network here started flaking out, and we have people in other countries relying on this server too). However, I'm not sure how best to migrate the data into the data centre without rendering the connection unusable during office hours, because there's far too much to send in over night over the two meg upstream connection we have here. I'm familiar with using tools like nice to stop a long running process degrading machine performance - is there a simple way to throttle a connection between office hours, so the long running transfer doesn't block the pipe, but then opens up outside of office hours to make the most of the bandwidth? I'm aware the alternative here is to simply mail a hard drive to the data centre, but I'd like to avoid doing that if I could. We're using Centos Linux for our servers, in the office and the datacentre, so extra points for an open source linux answer.

  • Traverse tree with results. Maybe type in Java?

    - by Angelo.Hannes
    I need to check a tree's node state. It can either be OK or NOT_OK. But that state is dependent on its children. So for a node to be OK, every of its children needs to be OK. If one or more of its children is NOT_OK the whole node is NOT_OK. To determine the state of a node I need to aggregate some properties of the node. So I thought of two possible implementations. And they are more or less covered in this question: Why is Option/Maybe considered a good idea and checked exceptions are not? Exception I could pass the properties up the recursion path, and throw an exception if something went wrong. Maybe I implement an Maybe type and let it either hold an error or the aggregated properties. Maybe it is more an Either. I tend towards the last option. And I'm thinking of an enum with two objects. Where I can additionally set those aggregated properties. Am I on the right track? I'm not familiar with the new JDK8 functional stuff. But I'm stuck on JDK7 anyway, so please focus on JDK7.

  • How can I troubleshoot SSD disconnection problems on Windows 7?

    - by 0xC0000022L
    I have a small SSD (Transcend StoreJet TS256GESD200K) which I am using on several computers. The drive is formatted with NTFS and recently I started noticing disconnects. Normally one probably wouldn't notice (you don't even get the notification sound in Windows when it disconnects), but since I use USBDLM and run a VM from that SSD, I get to see this first-hand. How could I best figure out whether the problem is the hardware (SSD, USB socket, USB cable or something in the PC) or software? In short: how can I locate the source of the disruption so that I can work on removing the problem? Side-note: SMART status for the SSD is clean.

  • Saving mobile application data when no service?

    - by Abe Miessler
    Say I have a mobile application that allows users to enter information which is then uploaded to a central location. I had planned on building this using only HTML5 and javascript (non-native app), but I'm assuming if someone is in an area where there is no service they simply will not be able to use the app. As a work around would it be possible to write a native app that saves the information on the device and then uploads it whenever service returns? If so, is it possible to write a native app entirely in HTML5 and Javascript that does this?

  • 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!

  • Daisychain external USB drive to WD My Book World Edition (Blue rings)

    - by d03boy
    I recently bought a new My Book Essential 1TB (WDBACW0010HBK-NESN) to daisychain to my older My Book World Edition 500GB (blue rings) with one of the version 01.xx.xx firmwares. At first when I connected the USB drive to the MBWE, it showed up in the System Summary section of the administration page without any issue. I was able to set up a new share on the new drive. The administration website moved very, very slow though. The administration pages became nearly unresponsive during this setup process. Once the share was set up I could access the new share but again, it was very slow, now through Windows Explorer. I looked around the internet and it seems that this is caused by the USB drive being formatted with NTFS. I tried reformatting it (again, as NTFS) just to double check and the same problem occurred. I then tried FAT32 but realized it would only support files of approximately 2GB and that is not acceptable for me. I decided to try a firmware upgrade on the MBWE to version 02.00.19. The firmware upgrade completed successfully but now the MBWE does not display the USB drive in the System Summary like it did with the earlier firmware version. The USB drive works perfectly fine when connected directly to my computer. Is there a way to solve this issue?

  • Sync Banshee library data.

    - by Dom
    I use Banshee to organise my music, I particularly like its scoring system and I have smart playlists based on it. However, I have two versions of my music library, one on each of my computers. As one of the computers is small I only have a favourite set of songs on that computer rather than my whole collection. The computers are not on a local network, but I do use Ubuntu One for file sharing between them. Is there any way I can synchronise song data (play count, score, skip count ...) and playlist data (including smart playlists that include songs based on this data) between the two computers? This would only be relevant of course for the songs that exist on both computers, the songs that exist on only one would need to be ignored. I did consider putting the library data file (I think it is .xml but I'm not sure) into the shared file and creating a symbolic link to it, but then I wouldn't be able to have a different set of songs on each computer. Thank you.

  • Recovery from hell - undeleting partition overwritten by Xubuntu 12.10 installer?

    - by DaimyoKirby
    This is turning into a nightmare - following my initial recovery of my two partitions, I went to install Xubuntu 12.10 (again). At this time I had two partitions - one of ~39 GB had Zorin OS 6 installed on it, and another of ~33 GB had nothing installed, just a few files in it that I had manually backed up (moved) there. When I got to the partitioning step, I chose "Replace Zorin OS 6 with Xubuntu 12.10", along with LVM, naturally thinking that the installer wouldn't touch the second partition, since Zorin wasn't installed on it. I was dead wrong. Upon booting my newly installed Xubuntu 12.10, I found in gparted that there were only two partitions - ~255MB, which appears to have the boot stuff in it (it's flagged boot in gparted), and another of ~74 GB. Question: Is there any way to salvage my old files on the non-Zorin ext3 partition? I'm really upset I made such a dumb move (again...), and any and all help is appreciated very, very much!

    I'm planning to develop a C# widows based application for an academy. The academy will have different instances of application running in different machines. The database should have shared access. All the application instances can do update, delete or insert. I've not done any network based application. Anybody can give any useful link to where to start with ? Which database would give max performance with all required features i said for this scenario ?

  • Adding more drives to a drive array

    - by Mystere Man
    I have a friend who has two servers, a Dell 1800 and an HP 350 ML G5, both have SAS drive arrays. The Dell is a 3.5" and the HP is a 2.5". They currently only have 3 drives in each array. We want to add additional drives, but they do not appear to have caddies, just "fake" covers. I haven't been able to take a good look at them, so I'm not sure what I need to do here. Are the "sockets" just there, and I can buy additional caddies and just stick them in? Or do I have to buy some kind of caddy adapter? Also, i'm thinking of just going 2.5" in the new server, so is there a 2.5" adapter caddy that will fit in the 3.5" chassis for the Dell, so I can use 2.5" drives in the 3.5" chassis? Can I buy 6GB/s drives and add them to the 3GB/s controller? The reason is that we're going to replace both computers in a year or so, and we want to bring the drives with. So rather than buy 3GB/s drives, we just want to buy 6GB/s drives so they can be used in the new server.

  • What is the advantage of iSCSI over SMB?

    - by sofakng
    At my house I'm running a Hyper-V server with a Windows Server 2008 R2 VM acting as a file server. Files are shared across my network using SMB. (Also, the machine is using a PERC 6/i RAID card but I don't think that's important) I'm thinking about setting up a dedicated SAN (iSCSI) machine and then switching my Hyper-V server to ESXi. What are the advantages of using iSCSI versus SMB? I think I would still need a file server OS (eg. Win 2k8) sharing files via SMB so I'm not sure the end result would be any different than my current setup...
