• Selectively Including files in C#.net web application [migrated]

  - by segnosaur

  I am attempting to modify an application with the following characteristics: Written in C#.net Using Visual Studio 2010 The application uses a Master sheet to maintain commonality The Master sheet has the following: <%@ Master Language="C#" AutoEventWireup="true" CodeFile="mysheet.master.cs" Inherits="master_mysheet" %> Now, currently, the master sheet has an include file that brings in a common footer: #include file="inc/my-footer.inc" Here's what I want to do: I would like to modify the master sheet to be able to read in a footer based on the value contained in a session variable... i.e. (not real code, but just something to give an idea of what I want) if session("x") = "a" then #include file="inc/my-footer1.inc" else #include file="inc/my-footer2.inc" My first instinct was to go with some vbscript: <script type="text/vbscript" language="vbscript"> document.write("vbscript example.") </script> However, it doesn't run the vbscript code automatically on page load. Does anyone know: - The syntax I need to actually get this to work? i.e. to get the vbscript to run automatically on page load, AND to do the page include? - Or, is there a better way to go about this? (perhaps by doing some coding in C#) Note: I am experienced in C#; however, I haven't done any vbscript since the days of ASP classic, so my knowledge there is out of date.

• Why would my HDD main partition suddenly become hidden?

  - by Luis Oscar

  A few days ago I was using my computer as usual and I turned it off. The next day it wouldn't boot up. It just stayed after the hardware diagnostic window on the intermittent underscore screen. So clearly It wasn't booting up. I tried turning it on and off a couple of times with no avail. Finally I used windows 7 disk and it seemed as if there was no HDD. not even the installation would see the HDD. So i thought it was dead, i bought a new one installed it with windows and used a external case with the old HDD. plug it in and still couldn't see it. I finally downloaded a partition program EASUS or something and my HDD was there listed WITHOUT a system letter. I could however explore it and i set it as Unhidden and it came back to life. I could see it normally. I really just wish someone could explain to me what happened here, was it a virus? does it means the HDD is about to die? How can i prevent this or what should I do now? should i stop using this OLD HDD? Thanks

• Generating new SID for Windows 7 cloned partition in Linux?

  - by Jack

  So I've read that the proper way to clone a Windows 7 partition is to run a Sysprep after the clone is complete. For MANY reasons, this is not possible the way we are cloning these drives (long story short, the drive should be fully up and running after we clone it, with all the settings already there and requiring no user intervention; and no, not even an answer file would work because the way we customize all the Win7 settings is complex and we do not want the user touching the settings). I understand Microsoft will not support Windows 7 clones if it is not sysprepped and that is fine for us. Acronis recovery tools get around this by ticking an option called "Create new NT signature", which resets the SID and GUID on any restore. Symantec has a tool called Ghostwalker which does the same thing. However, we are looking for a way to do this in Linux because we want to use open source tools to do the imaging (fsarchiver, partclone, etc. basically the same tools Clonezilla uses internally to clone NTFS partitions). The question is, if we clone using these tools in Linux, how would we generate a new SID thereafter (without the use of sysprep)? Is there any way to do it within a Linux environment? The whole image process is automated so if it is a simple command that I can just throw in my shell script, that would be even better. Of course, it would be nice to know if this is even possible. Any ideas? EDIT: Forgot to mention that the target machines we are restoring the image on are EXACTLY the same.

• How to chain GRUB2 for Ubuntu 10.04 from Truecrypt & its bootloader (multi boot alongside Windows XP partition)?

  - by Rob

  I want Truecrypt to ask for password for Windows XP as usual but with the standard [ESC] option, on selecting that, i.e via Escape key, I want it to find the grub for the (unencrypted) Ubuntu install. I've installed Windows XP on the 120Gb hard drive of a Toshiba NB100 netbook then partitioned to make room for Ubuntu 10.04 and installed that after the Windows XP install. When I encrypt Windows XP, Truecrypt will overwrite the grub entry in the master boot record (MBR), I believe (?) and I won't be able to choose between XP and Ubuntu anymore. So I need to restore it back. I've searched fairly extensively for answers on Ubuntu forums and elsewhere but have not yet found a complete answer that covers all eventualities, scenarios and error messages, or otherwise they talk of legacy GRUB and not GRUB2. Ubuntu 10.04 uses GRUB2. My setup: Partitions: Windows XP, NTFS (to be encrypted with Truecrypt), 40Gb /boot (Ext4, 1Gb) Ubuntu swap, 4Gb Ubuntu / (root) - main filesystem (20gb) NTFS share, 55Gb I know that the Truecrypt boot loader replaces the GRUB when boot up because I've already tried it on another laptop. I want boot loader screen to look something like the usual: Truecrypt Enter password: (or [ESC] to skip) password is for WindowsXP and on pressing [ESC] for it to find the Ubuntu grub to boot from Thanks in advance for your help. The key area of the problem is how to instruct Truecrypt when escape key is pressed, and how the Grub/Ubuntu can be made visible to the truecrypt bootloader to find it, when the esc key is pressed. Also knowing as chaining.

• Is it the right time to get a Master's degree?

  - by harshit

  I'm currently a software engineer in India and have been working for 3,5 years. Before recession started I decided to study further and planned for a Master of Science degree in computer science in Fall09, since I want to explore more of this field. I have got an admission in Univ of Texas @ Dallas. I am confused about whether I should go for studying at the time of recession or not and how the market will be once I graduate in 2011 Jan. Any views will be appreciated.

• How do I setup a Master Page with ASP.net?

  - by Michael

  Hi there, I'm normally a ColdFusion developer, but I'm having to work on a new site using some ASP.net hosting only, so forgive me if my questions seem very trivial. For numerous reasons, the website will be relatively static in the sense that it will mainly be using includes etc...that's about as complex as it will get with this. Now, I heard about the ability to set a master in ASP.net. Would anyone please be able to explain to me in a step process on how to do this? I have of course been searching for some time now on this topic but most results yield little help or no help at all since the search terms are slightly ambiguous. It would be nice to have this functionality for the long run. Any help or advice would be great. Many thanks. Michael.

• I need to know how to create a custom webform template in ASP.NET that allows me to pick a master pa

  - by Pete

  Using Visual Studio 2008, I need to create a custom web form that when picked acts like the web content form, by providing a dialog that lets you pick a master page. I have looked through the webform.zip template and thought I had a clue, but trying different combinations has baffled me as it either doesn't appear or doesn't work. Also when you set the project type to Web and sub project type to CSharp it doesn't appear, so I don't know if this part of the cause, because I would of hoped that the SupportsMasterPage element would of caused this dialog to appear, if it is a web item, but no luck. Frown Any ideas? p.s. I have used my googling resources to the maximum so unsure what to do.

• On a Hudson master node, what are the .tmp files created in the workspace-files folder?

  - by Patrick Johnmeyer

  Question: In the path HUDSON_HOME/jobs/<jobname>/builds/<timestamp>/workspace-files, there are a series of .tmp files. What are these files, and what feature of Hudson do they support? Background Using Hudson version 1.341, we have a continuous build task that runs on a slave instance. After the build is otherwise complete, including archiving the artifacts, task scanner, etc., the job appears to hang for a long period of time. In monitoring the master node, I noted that many .tmp files were being created and modified under builds//workspace=files, and that some of them were very large. This appears to be causing the delay, as the job completed at the same time that files in this path stopped changing. Some key configuration points of the job: It is tied to a specific slave node It builds in a 'custom workspace' It triggers a downstream job that builds in the same custom workspace on the same slave node

• Blit Queue Optimization Algorithm

  - by martona

  I'm looking to implement a module that manages a blit queue. There's a single surface, and portions of this surface (bounded by rectangles) are copied to elsewhere within the surface: add_blt(rect src, point dst); There can be any number of operations posted, in order, to the queue. Eventually the user of the queue will stop posting blits, and ask for an optimal set of operations to actually perform on the surface. The task of the module is to ensure that no pixel is copied unnecessarily. This gets tricky because of overlaps of course. A blit could re-blit a previously copied pixel. Ideally blit operations would be subdivided in the optimization phase in such a way that every block goes to its final place with a single operation. It's tricky but not impossible to put this together. I'm just trying to not reinvent the wheel. I looked around on the 'net, and the only thing I found was the SDL_BlitPool Library which assumes that the source surface differs from the destination. It also does a lot of grunt work, seemingly unnecessarily: regions and similar building blocks are a given. I'm looking for something higher-level. Of course, I'm not going to look a gift horse in the mouth, and I also don't mind doing actual work... If someone can come forward with a basic idea that makes this problem seem less complex than it does right now, that'd be awesome too. EDIT: Thinking about aaronasterling's answer... could this work? Implement customized region handler code that can maintain metadata for every rectangle it contains. When the region handler splits up a rectangle, it will automatically associate the metadata of this rectangle with the resulting sub-rectangles. When the optimization run starts, create an empty region handled by the above customized code, call this the master region Iterate through the blt queue, and for every entry: Let srcrect be the source rectangle for the blt beng examined Get the intersection of srcrect and master region into temp region Remove temp region from master region, so master region no longer covers temp region Promote srcrect to a region (srcrgn) and subtract temp region from it Offset temp region and srcrgn with the vector of the current blt: their union will cover the destination area of the current blt Add to master region all rects in temp region, retaining the original source metadata (step one of adding the current blt to the master region) Add to master region all rects in srcrgn, adding the source information for the current blt (step two of adding the current blt to the master region) Optimize master region by checking if adjacent sub-rectangles that are merge candidates have the same metadata. Two sub-rectangles are merge candidates if (r1.x1 == r2.x1 && r1.x2 == r2.x2) | (r1.y1 == r2.y1 && r1.y2 == r2.y2). If yes, combine them. Enumerate master region's sub-rectangles. Every rectangle returned is an optimized blt operation destination. The associated metadata is the blt operation`s source.

• How to cleanly add after-the-fact commits from the same feature into git tree

  - by Dennis

  I am one of two developers on a system. I make most of the commits at this time period. My current git workflow is as such: there is master branch only (no develop/release) I make a new branch when I want to do a feature, do lots of commits, and then when I'm done, I merge that branch back into master, and usually push it to remote. ...except, I am usually not done. I often come back to alter one thing or another and every time I think it is done, but it can be 3-4 commits before I am really done and move onto something else. Problem The problem I have now is that .. my feature branch tree is merged and pushed into master and remote master, and then I realize that I am not really done with that feature, as in I have finishing touches I want to add, where finishing touches may be cosmetic only, or may be significant, but they still belong to that one feature I just worked on. What I do now Currently, when I have extra after-the-fact commits like this, I solve this problem by rolling back my merge, and re-merging my feature branch into master with my new commits, and I do that so that git tree looks clean. One clean feature branch branched out of master and merged back into it. I then push --force my changes to origin, since my origin doesn't see much traffic at the moment, so I can almost count that things will be safe, or I can even talk to other dev if I have to coordinate. But I know it is not a good way to do this in general, as it rewrites what others may have already pulled, causing potential issues. And it did happen even with my dev, where git had to do an extra weird merge when our trees diverged. Other ways to solve this which I deem to be not so great Next best way is to just make those extra commits to the master branch directly, be it fast-forward merge, or not. It doesn't make the tree look as pretty as in my current way I'm solving this, but then it's not rewriting history. Yet another way is to wait. Maybe wait 24 hours and not push things to origin. That way I can rewrite things as I see fit. The con of this approach is time wasted waiting, when people may be waiting for a fix now. Yet another way is to make a "new" feature branch every time I realize I need to fix something extra. I may end up with things like feature-branch feature-branch-html-fix, feature-branch-checkbox-fix, and so on, kind of polluting the git tree somewhat. Is there a way to manage what I am trying to do without the drawbacks I described? I'm going for clean-looking history here, but maybe I need to drop this goal, if technically it is not a possibility.

• dual boot ubuntu installation mishap

  - by user590849

  I have Windows 7 pc ,where i had 2 partitions, a c drive for my system files and a d drive for my data. I decided to install ubuntu 11.10 a couple of days ago and thought of install it in a separate partition of its own. So i made a separate Linux partition of 30GB. I downloaded ubuntu on my usb stick and installed. During the installation process i was asked where to install ubuntu so i opened up a screen that was similar to this one There were six partitions present ( I had made only 3 partition via windows). Their names were totally different from the ones that i had given in windows. So i selected a drive which had the same size as my Linux partition that i had made in windows ( no other partition had the same size). I clicked on install now and got an error message saying that "There was no root folder set". I set the newly made partition as my root folder and clicked install now. Now out of the 6 partitions that were created 3 were logical ( i had only created 3 partitions in windows). As soon as i clicked install now, the system asked me where i wanted to put my "swap space". I selected one of the logical drives and hit install. Ubuntu successfully installed on my system and at the end it asked me to reboot. I did and got the following error message: "missing operating system". I was shocked. I tried my windows recovery disk ( that i had gotten when i had purchased my laptop) and there i went into startup repair. In the startup repair option i was not able to locate windows. The system asked me to click the "Load drivers" button to load the drivers to my harddrive where windows was installed, but i could not locate any drivers to my harddrive. I tried this several times but to no success. I panicked and installed ubuntu, now this time click "ok" at every step( not worrying about the partition and all). The os installed correctly and i am now able to access my harddrive. NO data within the c drive is lost. All the windows system files are intact. I wish to recover my windows installation. How do i go about it? Thank you in advance. I do not want to format my computer and install windows again.

• Non-standard installation (installing Linux from Linux)

  - by Evan Plaice

  So, here's my setup. I have one partition with the newest version installed, a second partition with an older version installed (as a backup just in case), a swap partition that both share, and a boot partition so the bootloader doesn't need to be setup after each upgrade. Partitions: sda1 ext3 /boot sda2 ext4 / (current version) sda3 ext4 / (old version) sda4 swap /swap sda5 ntfs (contains folders symbolically linked to /home on /) So far it has been a very good setup. I can create new boot loaders without screwing it up and adding my personal files into a new install is as simple as creating some symbolic links (the partition is NTFS in case I need to load windows on the system again). Here's the issue. I'd like to be able to drop the install into /distro on the current version and install a new version on / on the old version effectively replacing/upgrading it. The goal is to be able to just swap out new versions as they are released while maintaining redundancy in case I don't like th update. So far I have: downloaded the install.iso created a folder in /distro copied the install.iso into /distro extracted vmlinuz and initrd.lz into /distro Then I modified /boot/grub/menu.lst with the following entry: title Install Linux root (hd0,1) kernel /distro/vmlinuz initrd /distro/initrd.lz vmlinuz loads perfectly but it says it can't find initrd.lz on boot. I have also tried to uncompress the image with: unlzma < initrd.lz > initrd.img And, updating the menu.lst file to match; but that doesn't work either. I'm assuming that vmlinuz (linux kernel) loads, fires up the virtual filesystem by creating a ramdisk (initrd), mounts the iso, and launches the installer. Am I missing something here? Update: First, I wanted to say that the accepted answer would have been the best option if I was doing a normal Ubuntu install. Unfortunately, I was installing Linux Mint (which lacks the script needed to make debootstrap work. So the problem I with the above approach was, I was missing the command that vmlinuz (linux kernel) needed to execute to start boot into LiveCD mode. By looking in the /boot/grub/grub.cfg file I found what I was missing. Although this method will work, it requires that the installation files reside on their own partition. I took the easy route and used unetbootin to drop the LiveCD on a usb drive and booted from that. Like I said before. Debootstrap would have been the ideal solution here. Even though I couldn't use it I wrote down the steps it would've taken to use it. Step One: Format sda3 (the partition with the old copy of linux that's being overwritten) I used gparted to format it as ext4 from within the current linux install. How this is done varies based on what tools you prefer to use. Step Two: Mount the newly formatted partition (we'll call the mount ubuntu for simplicity) sudo mkdir /mnt/ubuntu sudo mount -o -loop /dev/sda3 /mnt/ubuntu Step Three: Get debootstrap sudo apt-get install debootstrap Step Four: Mount the install disk (replace ubuntu.iso with the name if your install disk) sudo mkdir /media/cdrom sudo mount -o loop ~/ubuntu.iso /media/cdrom Step Five: Install the OS using debootstrap (replace fiesty with the version you're installing and amd64 with your processor's architecture) sudo debootstrap --arch amd64 fiesty /mnt/ubuntu file:/media/cdrom The settings here varies. While I loaded debootstrap using an install iso, you can also have debootstrap automatically download and install if with a repository link (While most of these repositories contain debian versions I'm still not clear as to whether Ubuntu has similar repositories). Here a list of the debian package repositories and their mirrors. This is how you'd deploy debootstrap if you were doing it directly from a repository: sudo debootstrap --arch amd64 squeeze /mnt/debian http://ftp.us.debian.org/debian Here's the link that I primarily used to figure this out.

• UEFI Dual-Boot - Ubuntu 12.04.3 + Windows 8.1 (One GPT HDD)

  - by swafbrother

  UEFI Dual-Boot - Ubuntu 12.04.3 + Windows 8.1 (One GPT HDD) Hello, I'm having trouble setting up a dual-boot (Ubuntu 12.04 LTS and Windows 8.1) in my ASUS K55VM laptop's hard drive disk (500 GB). I was mostly following tutorials for doing this, but at some point something has gone wrong. Up to now, I have followed these steps: I formatted my HDD into GPT. I clean-installed Windows 8.1. I didn't prevent Windows from choosing the partitions to use and it created these partitions: A Recovery partition (sda1). An EFI System Partition (sda2). A Microsoft Reserved Partition (sda3). A Windows Data Partition or C drive (sda4). I reduced the Windows Data Partition via Windows' Disk Management. I made a bootable USB Stick with Ubuntu 12.04 LTS from ISO, using Universal USB Installer. I created these partitions for Ubuntu: A Boot partition, mounted at /boot (sda5). A Root partition, mounted at / (sda6). A Swap partition (sda7). In Device for boot loader installation I chose: /dev/sda. Then, when I rebooted, it went straight into Ubuntu. So I installed Boot-Repair, and clicked on Recommended Repair. It automatically did its job without asking for anything. I rebooted and Grub showed up, with a lot of options. At this point I had a decent dual-boot setup; Ubuntu and both Windows entries worked fine: Ubuntu. Windows Boot UEFI Loader. Windows UEFI bkpbootmgfw.efi. I executed this command: sudo grub-install --force /dev/sda5. Then I tried to make Windows 8.1's Boot Manager the main boot manager, so that I could choose which OS to boot into from a menu. I downloaded EasyBCD on Windows. It showed 2 Ubuntu entries and 1 Windows entry. I went into BCD Deployment tab and clicked on Write MBR. At this point, I went into BIOS and made Windows Boot Manager the first boot option. When I rebooted, I got a black screen with the message efidisk read error, and then (I guess) it switched to the next boot option, which is Ubuntu, resulting in Grub showing up. From Grub, Ubuntu entry is working and so are both Windows entries. If I choose Ubuntu, it normally boots into Ubuntu. But if I choose Windows, it goes into Windows' boot manager. In Windows' boot manager, a menu shows up: Ubuntu. Ubuntu. Windows 8.1. If I choose Windows, it boots into Windows without any problem. If I choose Ubuntu, it boots into Grub (back to step 14). Here's my BootInfo Summary: http://paste.ubuntu.com/6698171/ Windows Boot Manager is clearly not working as expected; I can't directly boot into it and I can't boot into it from BIOS either (efidisk read error again). If I want to boot into Windows I need to boot into Grub first, which is the opposite of what I wanted. I need help at this point. What is the best thing I can do? Is there a more reliable and/or simpler way of acomplishing a satisfying dual-boot for this situation? Can someone provide a way for going back to step 8, where I had a more efficient dual-boot setup? If only I could undo what I did with Easy BCD and skip Windows' Boot Menu... Can someone provide a way to fix this mess? Thanks in advance and sorry for the length of this, I wanted to be exhaustive.

• Possible to make mysql server both master and slave?

  I am getting ready to move a database from one server to another. In order to reduce downtime for the client, I am wondering if it would be possible for me to turn on replication and give it time to replicate fully, then just point the customer to the new server. The issue I have is that the server I'm moving to has existing, active databases for other customers. And, the server I'm moving from has other active customers who will not be moving at this time. Is this even possible? If so, how do I configure the server I am moving from and the one I am moving to?

• Grub Rescue Unknown Filesystem Error. Grub Corrupted or Filesystem?

  - by nightcrawler

  Now it has happened twice & have been pulling my hairs now... I have installed xubuntu on my external hardisk & have been using it for about 3 months. It has three partitions, one of 500 mb mounted at /boot, 2nd one of 48gb mounted at / & the rest (out of 160gb) is ntfs partition....used as normal external storage. The last storage supposedly acts as a buffer b/w Linux distributions & Win platform, buffer in the sense that it provides a universal channel for data transfers. I have constantly used this external hardisk for data transfers b/w win7 laptop & xubuntu (on this external hd) without any hassle. However, on of my desktops where I have ubuntu I (for the first time) attached this external drive which let me do data transfers where all three partitions properly mounted....but then nasty thing occurred the same that occurred before. I (as usual) tried booting via this external hd (one having xubuntu, one having being formerly used under Ubuntu) I got error Now I am totally devastated because similar thing happened ~6months before when I had fedora 17 in my external hd (instead of xubuntu) & after it was used under ubuntu the same happened...i didn't reported it because I already had planned towards debian instead of rpm! The mystery is that as long as I don't attach this external hd under ubuntu the data never** corrupts whereas under win xp/7 I can use it as a normal usb storage of coarse linux partitions aren’t available under win platforms... **From corrupts I mean hd fails to boot with the error mentioned however cant say whether data within remains untouched? It seems that my grub & or MBR is corrupted. Please sir guide me to solve this issue also why I cant attach & use linux external hds under linux platform Disk /dev/sdc: 160.0 GB, 160041884672 bytes 255 heads, 63 sectors/track, 19457 cylinders, total 312581806 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0004e7d0 Device Boot Start End Blocks Id System /dev/sdc1 * 2048 976895 487424 83 Linux /dev/sdc2 978942 96874495 47947777 5 Extended /dev/sdc3 96874496 312575999 107850752 7 HPFS/NTFS/exFAT /dev/sdc5 978944 94726143 46873600 83 Linux /dev/sdc6 94728192 96874495 1073152 82 Linux swap / Solaris I can recall for sure that have seen a thread here when a similar problem occurred & in response someone gave solution of how to mount (now invisible) partitions & recover important data in them. I have misplaced that URL so if any can guide me thither because my important documents resides in / partition What I already have done: Without success I have tried this & related solutions What I plan to do: I believe that filesystem has corrupted & would you recommend solution like this provided I cant recall whether my /boot (500mb) partition was ext4 or ext2 though I am sure that my / (48gb) partition was ext4 UPDATE 1 Attached my external hd under Ubuntu ran followinf command as root grub-install /dev/sdc where /dev/sdc was my external hd containing corrupted xubuntu....it reported all done!

• mercurial: how to synchronize mq patches from a master repo as mq patches to a set of clone repos

  - by dim

  I have to run a dozen of different build tests on a code base maintained in a mercurial repository. I don't want to run serially these tests on same repository because they modify a set of common files and I want to run them in parallel on different machines. Also, after all tests are run I want to have access to latest test results from those test work areas. Currently I'm cloning the master repository a dozen of times and run in each clone one different test. Before each test execution I do a pull/update/purge preparation sequence in order to start the test on latest clean state. That's good for me. I'm also preparing new changes using mq extension that I would test on all clones as above before committing them. For testing some ready candidate mq patches I want somehow to deploy/synchronize them to be available in test clones and apply those ready for testing using some guard before running the test. Did anybody do this synchronization before? What's the most simple way to do it? Do I need to have versioned mq patches for that?

• I have two choices of Master's classes this fall. Which is the most useful?

  - by ahplummer

  (For background purposes and context): I am a Software Engineer, and manage other Software Engineers currently. I kind of wear two hats right now: one of a programmer, and one as a 'team lead'. In this regard, I've started going back to school to get my Master's degree with an emphasis in Computer Science. I already have a Bachelor's in Computer Science, and have been working in the field for about 13 years. Our primary development environment is a Windows environment, writing in .NET, Delphi, and SQL Server. Choice #1: CST 798 DATA VISUALIZATION Course Description: Basically, this is a course on the "Processing" language: http://processing.org/ Choice #2: CST 711 INFORMATICS Course Description: (From catalog): Informatics is the science of the use and processing of data, information, and knowledge. This course covers a variety of applied issues from information technology, information management at a variety of levels, ranging from simple data entry, to the creation, design and implementation of new information systems, to the development of models. Topics include basic information representation, processing, searching, and organization, evaluation and analysis of information, Internet-based information access tools, ethics and economics of information sharing.

• SQL: How do I INSERT primary key values from two tables INTO a master table.

  - by Stefan

  Hello, I would appreciate some help with an SQL statement I really can't get my head around. What I want to do is fairly simple, I need to take the values from two different tables and copy them into an master table when a new row is inserted into one of the two tables. The problem is perhaps best explained like this: I have three tables, productcategories, regioncategories and mastertable. --------------------------- TABLE: PRODUCTCATEGORIES --------------------------- COLUMNS: CODE | DESCRIPTION --------------------------- VALUES: BOOKS | Books --------------------------- --------------------------- TABLE: REGIONCATEGORIES --------------------------- COLUMNS: CODE | DESCRIPTION --------------------------- VALUES: EU | European Union --------------------------- --------------------------- TABLE: MASTERTABLE --------------------------- COLUMNS: REGION | PRODUCT --------------------------- VALUES: EU | BOOKS --------------------------- I want the values to be inserted like this when a new row is created in either productcategories or regioncategories. New row is created. --------------------------- TABLE: PRODUCTCATEGORIES --------------------------- COLUMNS: CODE | DESCRIPTION --------------------------- VALUES: BOOKS | Books --------------------------- VALUES: DVD | DVDs --------------------------- And a SQL statement copies the new values into the mastertable. --------------------------- TABLE: MASTERTABLE --------------------------- COLUMNS: REGION | PRODUCT --------------------------- VALUES: EU | BOOKS --------------------------- VALUES: EU | DVD --------------------------- The same goes if a row is created in the regioncategories. New row. --------------------------- TABLE: REGIONCATEGORIES --------------------------- COLUMNS: CODE | DESCRIPTION --------------------------- VALUES: EU | European Union --------------------------- VALUES: US | United States --------------------------- Copied to the mastertable. --------------------------- TABLE: MASTERTABLE --------------------------- COLUMNS: REGION | PRODUCT --------------------------- VALUES: EU | BOOKS --------------------------- VALUES: EU | DVD --------------------------- VALUES: US | BOOKS --------------------------- VALUES: US | DVD --------------------------- I hope it makes sense. Thanks, Stefan

• GRUB is not Booting Correctly

  - by msknapp

  I have a PC with three hard disks. Windows 7 is installed on the first, Ubuntu 14.04 is installed on the third. After I re-booted, it went straight to Windows 7. So I tried explicitly telling my PC to boot using the third hard disk, but that just takes me to the grub rescue prompt. I followed Scott Severence's instructions here to try and recover. Essentially, I updated grub, reinstalled grub, and then updated it again. After re-booting, absolutely nothing had changed. So instead I tried using the boot-repair tool. In the past it had failed for me, saying that I had programs running and it could not unmount drives, when I was running nothing. I never figured out how to solve that problem, but it went away when I bought another hard drive and used that for my Ubuntu installation, I don't know why. In any case, I ran the boot-repair tool and this time it said it was successful. First time for everything right? I re-booted, only to be taken straight to the grub rescue prompt. So I changed my BIOS settings to use the third hard disk for boot start up. That is the same hard drive where I have Ubuntu and grub installed, and the same one that the grub-repair tool told me to use. It still took me straight to the grub rescue prompt. So I went from not being able to boot Ubuntu, to not being able to boot either OS installed on my system. Thanks boot-repair! Boot repair gave me this URL for future troubleshooting: http://paste.ubuntu.com/8131669 When I try to boot from the third hard disk, this is my console: Loading Operating System ... error: attempt to read or write outside of disk 'hd0'. Entering rescue mode... grub rescue> grub rescue> set cmdpath=(hd0) prefix=(hd0,gpt2)/boot/grub root=hd0,gpt2 grub rescue> ls (hd0) (hd0,gpt3) (hd0,gpt2) (hd0,gpt1) (hd1) (hd2) (hd2,gpt2) (hd2,gpt1) (hd3) Those values look correct to me. I have also experimented with changing some of those values, but 'insmod normal' always throws the same error. Somebody please tell me how to fix this. I have tried everything, reinstalling grub, and running boot-repair. =========================== Update: I think the problem might be that the ubuntu installer did not partition my hard disk correctly. I booted from live USB and then launched gparted and looked at how it partitioned things. This is what gparted says: Partition, File System, Size, Used, Unused, Flags /dev/sda1 (!), unknown, 1.00 MiB, ---, ---, bios_grub /dev/sda2, ext4, 2.71 TiB, 47.30 GiB, 2.67 TiB, /dev/sda3, linux-swap, 16.00 GiB, 0.00 B, 16.00 GiB, So that first line looks problematic. It is supposed to be the /boot partition. However, it was given only 1 MiB? I am assuming that MiB is actually supposed to mean megabyte, no idea why that 'i' is there. It also says the file system is unknown. I read the answer by andrew here, and he says he had to do a custom install, explicitly configuring the boot partition. So I think that maybe Ubuntu's installer has a bug in it, where it does not set up the boot partition correctly if you are not installing on the first hard disk in your computer. I am going to try reinstalling with a custom partition scheme. I read elsewhere (askubuntu won't let me post another link) that I don't even need a /boot partition any more. So instead of following Andrew's instructions ver batim, I'm first going to try having just two partitions: one for /, and another for my 16GB swap space. Both as primary partitions. The first will be formatted as ext4. If that doesn't work, I may try again using /boot. ======================== So I did my custom install with no /boot partition, and it did not work. When I rebooted, I had an error message saying that some address did not exist. So for the hundredth time, I booted from the live USB, and ran boot-repair. Now I get this message GPT detected. Please create a BIOS-Boot partition (>1MB, unformatted filesystem, bios_grub flag). This can be performed via tools such as Gparted. Then try again. I feel like I'm running in circles and nobody will help me.

• Question about 'git branching'

  - by michael

  Hi, I read this about git branch: http://book.git-scm.com/3_basic_branching_and_merging.html so I follow it and create 1 branch : experimental And I 1. switch to experimental branch (git checkout experimental) 2. make a bunch of changes 3. commit it (git commit -a) 4. switch to master branch (git checkout master) 5. make some changes and commit there 6. switch back to experimental (git checkout experimental) 7. merge master change to experimental (git merge master) 8. there are some conflicts but after I resolve them, I did 'git add myfile' And now i am stuck, I can't move back to master when I do $ git checkout master error: Entry 'res/layout/my_item.xml' would be overwritten by merge. Cannot merge. and I did: $ git rebase --abort No rebase in progress? and I did : $ git add res/layout/socialhub_list_item.xml $ git checkout master error: Entry 'res/layout/my_item.xml' would be overwritten by merge. Cannot merge. What can I do so that I can go back to my master branch? Thank you.
