• GetRef to capture methods?

  - by Thom Smith

  I've just discovered VBScript's GetRef function, which gets a reference to the function named by its argument. Is there any way to get a reference to a method in this way? I have a hunch that VBScript doesn't offer the sophistication of binding needed to do so, but it would sure be nice.

• How to change partitioning - may involve conversion of a partition from primary to extended

  - by george_k

  I am having trouble thinking through how I can achieve my partitioning goals. Now my partitions are: sda1 (winA) (primary) sda2 (winB) (primary) sda3 (/ for ubuntu) (primary) What I want to migrate into is (obviously partition numbers need not be exactly like that) sda1 (winA) (primary) sda2 (winB) (primary) sda3 (/boot) (primary) sda4 - extended which will contain sda5 (/home) sda6 (/ for ubuntu) sda7 (swap) I know I may be asking too much, but what would a way to do it? One way I have thought is Create a new primary partition for /boot and split it from the root partition into the new one. It shouldn't be too hard. Then the disk will have 4 primary partitions. Somehow convert the root ubuntu partition from primary to extended. Split that last partition in 3 extended partitions (root, /home, swap) and split the contents there. I am obviously stuck on the 2nd part. Another way could be (maybe easier): Create an extended partition (or two) Split /home there Somehow move everything except /boot to the extended partition. This way /boot will stay on the primary partition that exists now, and will be shrunk as needed, and everything else will end up to the extended partitions. This may sound better, but I'm not too sure how to do the 3rd part. Some details: The disk is almost empty, so I have space to move things around in it, shrink the ubuntu partition etc. I don't want to touch the windows partitions in any way. Reinstallation is not an option. Also using a different partitioning scheme with fewer partitions is not an option (for example not having a separate /boot) Any ideas?

• Kubuntu 12.04: Change login screen background?

  - by drezabek

  I am having trouble changing my login screen background. I can select the default wall paper, the Kde-default one, but when ever I select my own custom wallpaper, there is no image, just a solid color. Normally, I would just ignore it, but the thing that bugs me is that this is a fresh install of Kubuntu 12.04 64bit, and the OS before this one, the one I overwrote, I had no trouble using the exact same image as the background... Settings In the System Settings application, Login Screen settings, Background tab, enable background, Under "Background", selected Picture, under options, selected Position: Scaled. Colors: Single Color. Blending: No Blending.

• Using POST or SESSION to capture data

  - by Karinne

  Hi all! I'm currently working on web application using VB in ASP.NET. Right now I have 1 page with panels that we are using to show/hide depending on the flow. When the user first comes in, he/she is presented with a gridview containing a list of clients. Then the user, clicks a link from a row and is presented a form where he/she can update the clients' info. Originally, I had a HYPERLINKFIELD that put the clientId in the url, then I'd grab the url and do the code appropriately <asp:HyperLinkField Text='<%$ Resources:Resource, ManageClient %>' DataNavigateUrlFields="CLIENT_ID" DataNavigateUrlFormatString="~/clients/manage.aspx?clientId={0}" /> Now, I'm rethinking that and wondering if it's better to use SESSIONs to grab the clientID via this instead <asp:TemplateField Visible="false"><ItemTemplate><asp:Label runat="server" ID="hidClientId" Text='<%# Bind("CLIENT_ID")%>' Visible="false" /></ItemTemplate></asp:TemplateField> <asp:ButtonField Text='<%$ Resources:Resource, ManageClient %>' CommandName="Manage" /> Or use the POST method, which I'm not sure how it works in .NET (but I've used it in PHP) Any help would be greatly appreciated.

• AWS EC2 Oracle RDB - Storing and managing my data

  - by llaszews

  When create an Oracle Database on the Amazon cloud you will need to store you database files somewhere on the EC2 cloud. There are basically three places where database files can be stored: 1. Local drive - This is the local drive that is part of the virtual server EC2 instance. 2. Elastic Block Storage (EBS) - Network attached storage that appears as a local drive. 3. Simple Storage Server (S3) - 'Storage for the Internet'. S3 is not high speed and intended for store static document type files. S3 can also be used for storing static web page files. Local drives are ephemeral so not appropriate to be used as a database storage device. The leaves EBS which is the best place to store database files. EBS volumes appear as local disk drives. They are actually network-attached to an Amazon EC2 instance. In addition, EBS persists independently from the running life of a single Amazon EC2 instance. If you use an EBS backed instance for your database data, it will remain available after reboot but not after terminate. In many cases you would not need to terminate your instance but only stop it, which is equivalent of shutdown. In order to save your database data before you terminate an instance, you can snapshot the EBS to S3. Using EBS as a data store you can move your Oracle data files from one instance to another. This allows you to move your database from one region or or zone to another. Unfortunately, to scale out your Oracle RDS on AWS you can not have read only replicas. This is only possible with the other Oracle relational database - MySQL. The free micro instances use EBS as its storage. This is a very good white paper that has more details: AWS Storage Options This white paper also discusses: SQS, SimpleDB, and Amazon RDS in the context of storage devices. However, these are not storage devices you would use to store an Oracle database. This slide deck discusses a lot of information that is in the white paper: AWS Storage Options slideshow

• How to change the default desktop environment?

  - by Kshitiz Sharma

  I wanted to try out different desktop environments so I installed XFCE, KDE, GNOME, etc on top of Unity in Ubuntu 12.04 After a while I decided that I didn't like those other DEs and would stick to Unity. So I changed my default DE to Unity by configuring gdm. > sudo dpkg-reconfigure gdm Now I am able to choose my DE at login time and all of DEs are working properly. But the strange thing is that my boot up screen says 'lubuntu', my login screen is KDE, and my desktop is Unity. How and why is this happening? Why didn't my gdm configuration have any effect? Does login and boot up screen need to be configured separately from the DE? There are other similar questions here but they are not the same as this one. I do not want to remove the other enviroments I'm quite happy with having a list of DEs to select from. I want to know how to set proper defaults.

• How can I change my "Desktop bar"?

  - by d_Joke

  The problem: In Gnome 3.4 when I click the main menu, it's white. The text of the menu is also white. Original text: I have a problem. When I installed the new version of Gnome (3.4) the "Desktop bar" (I'm sorry, I don't know what's the real name of that bar, but is the bar on the top on Ubuntu 11.10) every time I click on the username icon, or the battery, etc., the menu comes on gray or white and the letters are white. I know maybe this is a stupid question but it annoys me. Besides, my username doest not appear on the login screen. I tried to reset my settings, I delete gnome, and check the Unsettings and CompizConfig but the problem is still there. Maybe I miss something on the process of looking on any configuration tool but I don't think so... Sorry if the question is something basic or even stupid but I'm new on Ubuntu and I'm experimenting whit it.

• enemy behavior with boundary to change direction

  - by BadSniper

  I'm doing space shooter kind of game, the logic is to reflect the enemy if it hits the boundary. With my logic, sometimes enemy behaves like flickering instead of changing the velocity. It's like trapped in the boundary and checking for if loops. This is my code for velocity changing: if(this->enemyPos.x>14) { this->enemyVel.x = -this->enemyVel.x; } if(this->enemyPos.x<-14) { this->enemyVel.x = -this->enemyVel.x; } How can I get around this? Its going out of boundary and don't know where to go and after sometimes its coming into field. I know whats the problem is, I dont know how to get around this problem.

• Can't change color of sprites in unity

  - by Aceleeon

  I would like to create a script that targets a 2d sprite "enemy" and changes their color to red (slightly opaque red if possible) when you hit tab. I have this code from a 3d tutorial hoping the transition would work. But it does not. I only get the script to cycle the enemy tags but never changes the color of the sprite. I have the code below I'm very new to coding, and any help would be FANTASTIC! HELP! hahah. TL;DR Cant get 3d color targeting to work for 2D. Check out the c#code below using UnityEngine; using System.Collections; using System.Collections.Generic; public class Targetting : MonoBehaviour { public List targets; public Transform selectedTarget; private Transform myTransform; // Use this for initialization void Start () { targets = new List(); selectedTarget = null; myTransform = transform; AddAllEnemies(); } public void AddAllEnemies() { GameObject[] go = GameObject.FindGameObjectsWithTag("Enemy"); foreach(GameObject enemy in go) AddTarget(enemy.transform); } public void AddTarget(Transform enemy) { targets.Add(enemy); } private void SortTargetsByDistance() { targets.Sort(delegate(Transform t1,Transform t2) { return Vector3.Distance(t1.position, myTransform.position).CompareTo(Vector3.Distance(t2.position, myTransform.position)); }); } private void TargetEnemy() { if(selectedTarget == null) { SortTargetsByDistance(); selectedTarget = targets[0]; } else { int index = targets.IndexOf(selectedTarget); if(index < targets.Count -1) { index++; } else { index = 0; } selectedTarget = targets[index]; } } private void SelectTarget() { selectedTarget.GetComponent().color = Color.red; } private void DeselectTarget() { selectedTarget.GetComponent().color = Color.blue; selectedTarget = null; } // Update is called once per frame void Update() { if(Input.GetKeyDown(KeyCode.Tab)) { TargetEnemy(); } } }

• Yet Another SQL Strategy for Versioned Data

  There is a popular design for a database that requires a built-in audit-trail of amendments and additions, where data is never deleted, but merely superseded by a later version. Whilst this is conceptually simple, it has always made for complicated SQL for reporting the latest version of data. Alex joins the debate on the best way of doing this with an example using an indexed view and the filtered index.

• SEO Package Deals Make a Change From Flushing the Toilet on Your Business

  SEO package deals could save your business from being flushed away - almost literally. Rather than using SEO package deals, does your online marketing go a little like this: save up enough money to pay for an article service to create a whole batch of custom SEO articles, submitting them all across the web, then do nothing for weeks while you save up for the next assault? If so, then your article marketing strategy is what I tend to refer to as lavatorial.

• A Change of Seasons...

  - by James Michael Hare

  As some of you already know, today is my last day at Scottrade. It has been a great place to work and I'll miss all the relationships I've formed over the last 5 years immensely! Starting Monday, I will be taking a new position at Amazon.com in Seattle. It should be an exciting new adventure and I look forward to sharing more about my experiences in the days to come! I do intend to continue blogging (after the move settles down) about C# as I'm able, and may mix in some Java as well as I rekindle (Amazon? Kindle? Get it? Okay, that was lame, I know...) my knowledge of the language for my new job responsibilities. I'll miss all the relationships I've developed with the .NET community in St. Louis and the surrounding area, and hope to come back sometime to participate in future Days of .NET conferences, if able! Stay tuned for more updates!

• Learning PostgreSql: Embracing Change With Copying Types and VARCHAR(NO_SIZE_NEEDED)

  - by Alexander Kuznetsov

  PostgreSql 9.3 allows us to declare parameter types to match column types, aka Copying Types. Also it allows us to omit the length of VARCHAR fields, without any performance penalty. These two features make PostgreSql a great back end for agile development, because they make PL/PgSql more resilient to changes. Both features are not in SQL Server 2008 R2. I am not sure about later releases of SQL Server. Let us discuss them in more detail and see why they are so useful. Using Copying Types Suppose...(read more)

• How can you replicate each row of an R data.frame and specify the number of replications for each ro

  - by wkmor1

  df <- data.frame(var1=c('a', 'b', 'c'), var2=c('d', 'e', 'f'), freq=1:3) What is the simplest way to expand the first two columns of the data.frame above, so that each row appears the number of times specified in the column 'freq'? In other words, go from this: >df var1 var2 freq 1 a d 1 2 b e 2 3 c f 3 To this: >df.expanded var1 var2 1 a d 2 b e 3 b e 4 c f 5 c f 6 c f

• Excel macro to change external data query connections - e.g. point from one database to another

  - by Rory

  I'm looking for a macro/vbs to update all the external data query connections to point at a different server or database. This is a pain to do manually and in versions of Excel before 2007 it sometimes seems impossible to do manually. Anyone have a sample? I see there are different types of connections 'OLEDB' and 'ODBC', so I guess I need to deal with different formats of connection strings?

• Hostmonster can't change domains around?

  - by loneboat

  (question imported from http://superuser.com/q/204439/53847 ) Horrible title, but I couldn't think of a succinct way to summarize it to fit. I have HostMonster for my web hosting. I have several domain names under the same account (using the same web space, IP address, etc...). Every HM account has one domain set up as the "main domain", and all other domains are "secondary". The only way I have ever encountered this being an issue is in trying to use HTTPS - since (from my limited understanding) HTTPS encrypts headers, you can't route HTTPS requests to different virtual hosts on a server - only unencrypted requests, since it must look in the request to know where to route it. When I registered for my account, I only had one domain name (A). I have since added domain names (B), (C), (D), etc... At one point I switched domain name (B) to be my "main" domain name - so I could use HTTPS with it. I have since sold domain name (B), and would like to make domain name (A) my "main" one again (as it was before), but HM support says, "no, once a domain name has been a 'main' domain name on an account once, we can't set it up to be a 'main' domain name again. You're welcome to use domains (C), or (D), though.". They tell me the only way to reuse domain (A) as a "main" domain would be to set up a new account and transfer over all my files. I'm confused here. If I have domains (D), (E), and (F), they say I'm welcome to make one of them my new main domain name, just never (A) again, since I've already "used" it once. Calls to support only reveal that they can't let me do it because doing so would somehow "break" my account. Can anyone think of any good reason why this should be so? The only thing I can think is that maybe they're using the domain names as keys in some database or something? But if that's the case, that's ridiculous - they need to reorganize their databases!
