• Software Center won't take into account my changed OpenID name: any idea?

  - by Pascal Av

  Failing to install IntelliJ from the Software Center, I realized my login is wrong in the /etc/apt/auth.conf entry that the install process generates. In this file, I see my original OpenID, that's the one which got automatically generated when signing up on Launchpad. It contains my last name so I changed it. I purged conf and binaries for Ubuntu One, reinstalled, deleted all listed "Devices" from app, all "Applications" from Launchpad. Deleted ~/.cache/software-center/, reboot, but still: When installing IntelliJ, the auth.conf file receives my original OpenID, not the modified one Problem is that the commercial subscription, for IntelliJ private PPA, uses my modified OpenID, so authentication attempt fails. I can't remove nor modify this subscription, even by changing back my OpenID into Launchpad. Any idea to solve this?

• Does this have anything to do with endian-ness?

  - by eSKay

  This piece of code: #include<stdio.h> void hello() { printf("hello\n"); } void bye() { printf("bye\n"); } int main() { printf("%p\n", hello); printf("%p\n", bye); return 0; } output on my machine: 0x80483f4 0x8048408 [second address is bigger in value] on Codepad 0x8048541 0x8048511 [second address is smaller in value] Does this have anything to do with endian-ness of the machines? If not, Why the difference in the ordering of the addresses? Also, Why the difference in the difference? 0x8048541 - 0x8048511 = 0x30 0x8048408 - 0x80483f4 = 0x14 Btw, I just checked. This code (taken from here) says that both the machines are Little-Endian #include<stdio.h> int main() { int num = 1; if(*(char *)&num == 1) printf("Little-Endian\n"); else printf("Big-Endian\n"); return 0; }

• Is it possible to import specific class from project propreties

  - by Alex

  I have 2 projects. First project need to include second. When I copy sources from second project to first I need to modify manually import path to R.java file. The problem is that I need to use SVN external link connection between this 2 projects, that is mean, one project (the bigger one) will take sources from another through svn and should be able to use it without any modifications. If I would be able to specify R.java file path anywhere in project properties it will resolve my problem by changing manually that path. Need to specify that package name of these 2 projects are different. Another solution to resolve this problem also would be accepted. Thank you.

• One subdomain is not working

  - by BFTrick

  Hello there, My main domain works just fine - www.example.com and a subdomain set up by another developer works as well - sub1.example.com. But when I try to set another subdomain up I go through the process everything seems to work. The software creates the default files where the subdomain files should go. But when I try to browse there it doesn't work. My host uses Plesk to do all of the hosting stuff. What do you think the problem is? I doubt it is some sort of cache issue because I had problems on my phone which I tried after problems on the pc. Maybe for some reason Plesk needs time to set this up? I have used Cpanel before and that works instantly.

• Passing values for multi-value parameter in SSRS query string

  - by Andy Xufuris

  I have two reports built using SSRS 2005. The first report is set to navigate to the second when a specific field is clicked. There is a multi-value parameter on the second report. I need to pass multiple values for this parameter in the URL query string when calling this report. Is there a way to pass multiple values for a parameter in the query string of a report? Or can you pass a parameter that will cause the Select All value to be selected?

• How to match data between columns to do the comparasion

  - by NCC

  I do not really know how to explain this in a clear manner. Please see attached image I have a table with 4 different columns, 2 are identical to each other (NAME and QTY). The goal is to compare the differences between the QTY, however, in order to do it. I must: 1. sort the data 2. match the data item by item This is not a big deal with small table but with 10 thousand rows, it takes me a few days to do it. Pleas help me, I appreciate. My logic is: 1. Sorted the first two columns (NAME and QTY) 2. For each value of second two columns (NAME and QTY), check if it match with first two column. If true, the insert the value. 3. For values are not matched, insert to new rows with offset from the rows that are in first two columns but not in second two columns

• Where does Ubuntu Software Center store its (language) settings?

  - by guntbert

  On a fresh install (13.04) I see a strange mix of languages in Software Center The menu (like my system language) is in English, but the descriptions are in German. I want the descriptions in English too. I am using a german keyboard and have German installed too (for giving support to students with German as system language :-)) In system settings I have moved German below English - so it should be ignored, I have logged out after that. I have cleared the "Software Center Cache" with Ubuntu Tweak. The picture remains the same.

• How to Synchronize Session / Security between ASP.NET and Tomcat?

  - by Jay Stevens

  I have an Asp.NET 3.5 application with security/authentication. I have a second application (built using GWT and running on Windows Tomcat) running on a different machine. I need to make the second application available to the user via a link generated from the .NET application. This part is easy, I have constructed the link in the asp.net page and the user can click on it to start working in the GWT/Tomcat session. My question is this... How do I set it up so that the Tomcat/GWT application is Only Accessible via the link in my asp.NET application? I don't want the user to be able to copy the link from my asp.net page and then share that with someone else who is not authenticated within my asp.net application.

• How do I arbitrarily reorder lines in a text file using a Unix shell?

  - by Tim Bellis

  I've got a text file with an arbitrary number of lines, e.g.: one line some other line an additional line one more here I'd like to write a script to reorder those lines based on a given order. e.g. An input of 2 1 3 4 would swap the first and second lines. An input of 3 1 2 4 would put the 3rd line first, the 1st line second, the 2nd line third and keep the 4th line fourth. I could hack something together, but I'm wondering if there's an elegant solution? I can use either bash or ksh.

• How to set a complex custom crontab in google-app-engine (java)?

  - by Shreeni

  I am building an app for which I need to set up cron jobs. What I want to do is to set the specific minutes in a hour where specific crons should run. For instance: Task1 at 1st minute of the hour Task2 on every second minute of the hour Task3 every 2 minute only in the second half of the hour Building this in the standard Unix cron format is reasonably straightforward, but could not figure out how to do it in the Google-App-Engine. The documentation does not list any non-trivial examples. Any suggestions on how to do it? Examples would be excellent.

• Fastest way for inserting very large number of records into a Table in SQL

  - by Irchi

  The problem is, we have a huge number of records (more than a million) to be inserted into a single table from a Java application. The records are created by the Java code, it's not a move from another table, so INSERT/SELECT won't help. Currently, my bottleneck is the INSERT statements. I'm using PreparedStatement to speed-up the process, but I can't get more than 50 recods per second on a normal server. The table is not complicated at all, and there are no indexes defined on it. The process takes too long, and the time it takes will make problems. What can I do to get the maximum speed (INSERT per second) possible? Database: MS SQL 2008. Application: Java-based, using Microsoft JDBC driver.

• System crashed while upgrading, now unable to recover. Please help

  - by longloop

  Yesterday while upgrading from 11.4 to 11.10, due to power cut my system crashed. Ubuntu is unable to boot. While booting I get two options in grub, one is for recovery mode and the other is for normal ubuntu booting (and others are also thr for mem check and booting to windows). When I try to boot it normally, it pauses booting while displaying ' Checking battery statues' . Though i am not using a laptop, I am on a desktop. And In recovery mode the menu has 4 options - resume boot, fsck , remount and root ( to goto shell prompt) . If I go to shell and type ' apt-get dist upgrade' , it shows - W: not using locking for read only lock file /var/lib/dpkg/lock E:unable to write to /var/cache/apt E:The package lists or status files could not be parsed or opened. Please instruct me to recover from this situation.

• How does Git know which Index blob to add to a tree?

  - by drozzy

  In Pro Git Ch9 the author says: Git normally creates a tree by taking the state of your staging area or index and writing a tree object from it. My question is how does git know which of two consequitive index entries to create the Tree object from? For example: $ echo 'First change' > one.txt $ git add one.txt $ find .git/objects -type f .git/objects/1f/755a7fffe4 //first index entry $ echo 'Second change' > one.txt $ git add one.txt $ find .git/objects -type f .git/objects/2d/234asdf2 //second index entry $ git commit -a -m "Initial commit" $ git cat-file master^{tree} 100644 blob 2d234asdf2 one.txt //How did it know not to take 1f755?? Does it just look at the blob timestamps? Also - what happens to the first blob created - no one is referencing it. Does it just get destroyed or forgotten?

• Multiple network installs with cached downloads

  - by popey

  I tend to do lots of Ubuntu installs, and I'd like them to be up to date from the moment I do them, and not have to install a bazillion updates as soon as the install finishes. I'd also like to cache those packages somewhere on a machine on my LAN, so I don't re-download all the packages every time. How easy is this to achieve? Is there a guide somewhere to making this happen? Bonus points if I don't have to burn any CDs or use USB sticks! Edit: I have noticed a lot of guides for PXE booting and would be tempted to set this up but every time I find one they seem to be old/outdated and broken. My home server runs 10.04 LTS.

• How can I run a complete application from RAM?

  - by pico

  When I do some stuff in background (unpacking, compiling, backup, etc.) my hdd is under load and for example, Firefox and Chromium take very long to start and react very slow. While my hdd is under load I have still plenty of free RAM and free CPU. How can I copy the whole Firefox or Chromium including all dependencies into RAM? I don't care about persistence, I just want to view some websites, videos, etc. There are instructions putting the cache into /dev/shm, but that didn't speed up so much. Getting the profile into the RAM drive might also be easy... But how to get the binaries with all dependencies into RAM?

• Wait window in a windows application

  - by Vinodtiru

  I basically need to show a wait window to the user. For this i have put two seperate window forms in the application. the first form is the main form with a button. The second one is a empty one with just a label text. On click of the button in Form1 i do the below Form2 f = new Form2(); f.Show(); Thread.Sleep(2000); f.Close(); My idea here is to show the wait window to the user for 2 second. But when i do this the Form 2 is not completely loaded because of which the label in it is blank. Please let me know your inputs on this.

• Wrong/corrupted icon in dash

  - by Swarnendu Biswas

  I am facing a problem with the dash not showing proper/actual icons for certain applications such as Google Chrome and Mozilla Daily Mail. Instead of getting the standard icons for these applications, I get to see a default icon for all the applications. I have added a snapshot to show the problem. The icons that are shown in the launcher once launched or in the /usr/share/applications directory are proper. I have tried rebuilding the icon cache, but that did not help. I have also tried switching to other icons themes. This issue does not appear with Gnome Shell or KDE. I have also tried deleting ~/.local/share/applications/menu-xdg, there was none in the first place. I am using Ubuntu 12.10. Any suggestions would be appreciated.
