• How do I change my username?

  - by Takkat

  Some time ago when I installed Ubuntu I chose a rather stupid username for my account that I do not want to use anymore. How do I change this (including the name of my home directory) without loosing settings for applications? How do I keep permissions and my keys for various authentification (e.g. email, SSH, GPG and more)? What settings could possibly get lost if I changed my username? Both, command-line and graphical solutions are appreciated.

• Get selected object from TreeView

  - by GoGoDo

  I've been working on a minor (first time) app with quickly and hit a hurdle - how do I get the selected row (the data) from a TreeView? The data to the TreeView is passed from a list of files in a directory, and I need to know which rows were selected (and thus which files were). What is the best way to do that? Here's the current code: self.treeview = self.builder.get_object("treeview") select = self.treeview.get_selection() select.connect("changed", self.on_tree_selection_changed) def on_tree_selection_changed(selection): model, treeiter = self.treeview.selection-get() if treeiter != None: print "You selected", model[treeiter][0]

• Avoid random disk names

  - by BarsMonster

  Hi! I have Ubuntu Server 10.04 1 system disk, and 5 disks in RAID-5 configuration. The problem is that names of these disks are changed from time to time, they are being randomly mixed from time to time (sda,b,c,d,e,f - so system disks might be sda, or sdc at different time for example).... is there any way to fix drive names, so that even if it's disconnected for example, no other drive can occupy this letter based on disk UUID or something?

  Redgate recently announced that the next version of reflector was no longer going to be free ( http://www.red-gate.com/products/dotnet-development/reflector/announcement ).

• Sample Code for the SSIS Book

  Yes, I know I’ve been gone for a long time. I haven’t professionally blogged for years. But, the good folks here, Adam and Peter have out of the goodness of their hearts, left my blog around and well, I though I’d check in. Since then, I’ve changed jobs, gotten divorced, bought a few more laptops, bunches of guitars, a snowboard or two, iPads, iPhones, a few cars, travel to India, Europe, Middle East, backpacked Scotland (and still damp), Nepal and all over the US.

• Using SQL Server's Output Clause

  When you are inserting, updating, or deleting records from a table, SQL Server keeps track of the records that are changed in two different pseudo tables: INSERTED, and DELETED. These tables are normally used in DML triggers. If you use the OUTPUT clause on an INSERT, UPDATE, DELETE or MERGE statement you can expose the records that go to these pseudo tables to your application and/or T-SQL code.

• Queries barely over the Cost Threshold for Parallelism

  - by jchang

  I had discussed SQL Server parallelism in Oct 2010, with my thoughts on the best settings for: Cost Threshold for Parallelism (CTP) and Max Degrees of Parallelism (MAXDOP) in Parallelism Strategy and Comments . At the time, I had intended to follow up with detailed measurements. So now a mere 2 years later, here it is. The general thought was that CTP should be raised from the default value of 5, and MAXDOP should be changed from unrestricted, on modern systems with very many cores, and most especially...(read more)

• Updated sp_indexinfo

  - by TiborKaraszi

  It was time to give sp_indexinfo some love. The procedure is meant to be the "ultimate" index information procedure, providing lots of information about all indexes in a database or all indexes for a certain table. Here is what I did in this update: Changed the second query that retrieves missing index information so it generates the index name (based on schema name, table name and column named - limited to 128 characters). Re-arranged and shortened column names to make output more compact and more...(read more)

• Running ARM(EL) executables on ARM(HF) system - Missing Symlink to dynamic Loader?

  - by Uhli

  I am using an Ubuntu 12.10 (ARMHF) distribution on a panda board. I want to run applications compiled for ARMEL. It was not possible due to a changed dynamic loader location (https://wiki.linaro.org/OfficeofCTO/HardFloat/LinkerPathCallApr2012) I succeeded by creating the following symbolic link /lib/ld-linux.so.3 - /lib/ld-linuxarmhf.so.3 Is there a way to install a portability package instead? Is there a reason why this is not done by the distribution? Thanks in advance

• Left Mouse Button not Working

  I recent changed from ubuntu to xubuntu 12.04. The install worked great for a few days, but suddenly the left mouse button stopped working. The right click and scroll bars work fine.

What could make my mouse stop working like that?

• Forced to be trained [closed]

  - by steeb

  is it OK to force employees to take a training in order to make them sign a contract to stay in the job for X years? Here I'm the only developer in the company and before this job I've developed in VB6, VB.Net and others. There are others technicians here but they query the database server to make reports and make little programs but do not spend all day in programming. I was hired here to manage some legacy data to be migrated to a new system and I used my experience to accomplish the task. I also have made some utilities and other developments. Since we went live with the new system I've been developing a lot of side programs, add-ons and changed the source code of it and basically I've been learning from it since then and became some sort of jack of all trades when some feature needs to be changed or corrected. I have one and a half year in this company but during the last 8 months I've been entirely programming in the system. There have been times when even the implementers ask me how I accomplish certain things. The issue here is that the company has come and told me and other co-workers (which do not program in the system but know basic programming and databases) to have a basic training to program for the new system's platform and when we finish it we will sign a contract to stay in the company for an unspecified time. They have offered also an unspecified better salary. I'm feeling very suspicious cause I know the basics of system and I don't understand why I have to take it, being known by everybody all developments I've made. I gathered with my boss and told him that I should not take that course because I feel that I can learn more with all the daily requirements I've been asked and they should save that money. But he responded me that I have to take it and sign after that. I think they want me to be with them for a long time, and I'd like to, but my opinion is that I would like to stay in the company because I feel comfortable in all laboral aspects (including salary) but not because I signed a contract forced to do more tasks and forced to say no if I have others and better job offers. What advice can you give me in this kind of situation?
