• The entity framework and database agnostic programming, possibilities?

  - by Theo

  We want to use the Entity Framework (.NET 4.0) to build applications that can deal with Sql Server, MySQL and Oracle. And maybe Sqlite too. It should be easy to switch the db vendor by some setting in a config file. Is this possible? I prefer real life examples! What kind of providers did you use?

• Importing Delicious export into Firefox 3

  - by Jordan Reiter

  The HTML export file from Delicious creates an HTML file that, while importable into Firefox, loses all of the tags, which pretty much misses the point of delicious. Every link I've found to do the import doesn't work: The online converter Delicious-to-Firefox 3 keeps throwing a server error; the "better" version is down I tried using the trick of syncing Delicious bookmarks to Flock and then restoring that file to my Firefox browser. Although the bookmarks are in Firefox, they don't show up anywhere. I know they're in Firefox because when I create a backup file, they're in the JSON file but they refuse to show in the browser anywhere (clicking on any tag shows an empty list) Basically, I'm looking for someone who has successfully imported their delicious bookmarks, with tags, into Firefox 3.6.13 (Mac).

• Why does Chrome not start correctly when using C# Process.Start?

  - by nbolton

  I'm able to start Chrome successfully using this C# code: Process.Start("chrome", "http://www.google.co.uk"); However, it does two things wrong: It does not navigate to the URL specified in arguments It does not re-use the existing Chrome window (it opens a new one) I've tried using ProcessStartInfo and setting UseShellExecute and LoadUserProfile just in case these did something, but this makes no difference. Any ideas?

• A simple Volume Replication Tool for large data set?

  - by Jin

  I'm looking for a solution to the following: Server A (Site A) - Win 2008 R2 - approx 10TB (15TB max) of data - well over 8 million files Server B (Site B) - Win 2008 R2 I want to assynchronously replicate Server A's volume to a volume on Server B for data redundancy. Something that I can say to my users, "go here for data" when/if Server A goes belly up due to machine problems, disaster, etc. Windows 2008 R2 does have DFS, but microsoft does not apparently support this large of a dataset (or more accurately, more than 8 million files - according to the docs I could find). I also looked at Veritas Volume Replication, but this seems almost too much as I would also require Veritas Volume Manager. There are numerous "back-up" software which makes a 1-1 backup, which would be ok, but since it will be transfering over internet, I'd like something that has compression during transfer like DFS has. Does anyone have any suggestions regarding this?

• Performing your own runtime analysis of your code in C#

  - by Matt

  I have written a large C# app with many methods in many classes. I'm trying to keep a log of what gets called and how often during my development. (I keep a record in a DB) Every method is padded with the following calls: void myMethod() { log(entering,args[]); log(exiting,args[]); } Since I want to do this for all my methods, is there a better way to do this then having to replicate those lines of code in every method?

• Hibernate orm for a view

  - by EugeneP

  How do you ORM a view? Is there any difference with a table in terms of reverse engineering? In my case, I have a whole pile of joined tables that will be read-only in an application. So, if I need sort of a 1 Object with all collections in proper order, instead of long chains of relationships - collection with another etc, it'll be simpler. What do you think and how do you accomplish this?

• Generating unobtrusive JS

  - by nico

  I have read quite a bit about unobtrusive JS and how to generate it and all that jazz... My problem is this: I have a website that heavily relies on mod_rewrite, so essentially all the pages requests are sent to index.php that generates the main structure of the page and then includes the appropriate page. Now, there are different sections in the site and each section uses different Javascript functions (e.g. for different AJAX requests). Now, if I just were to attach a function to the onload of the page obviously the thing would not work, as I do not have to initialise the same things for each page... so what is the best way to handle this situation? I hope the situation is clear, I'll be happy to clarify if needed

• How to debug and detect hang issue

  - by igor

  I am testing my application (Windows 7, WinForms, Infragistics controls, C#, .Net 3.5). I have two monitors and my application saves and restores forms' position on the first or second monitors. So I physically switched off second monitor and disabled it at Screen Resolution on the windows display settings form. I need to know it is possible for my application to restore windows positions (for those windows that were saved on the second monitor) to the first one. I switched off second monitor and press Detect to apply hardware changes. Then Windows switched OFF the first monitor for a few seconds to apply new settings. When the first monitor screen came back, my application became unresponsive. My application was launched in debug mode, so I tried to navigate via stack and threads (Visual Studio 2008), paused application, started and did not find any thing that help me to understand why my application is not responsive. Could somebody help my how to detect the source of issue.

• Java Deflater strategies - DEFAULT_STRATEGY, FILTERED and HUFFMAN_ONLY

  - by Keyur

  I'm trying to find a balance between performance and degree of compression when gzipping a Java webapp response. In looking at the Deflater class, I can set a level and a strategy. The levels are self explanatory - BEST_SPEED to BEST_COMPRESSION. I'm not sure regarding the strategies - DEFAULT_STRATEGY, FILTERED and HUFFMAN_ONLY I can make some sense from the Javadoc but I was wondering if someone had used a specific strategy in their apps and if you saw any difference in terms of performance / degree of compression. Thanks, Keyur

• What's a good anti-virus besides Kaspersky and Nod32?

  - by KeyStroke

  Hi there, I've been using Nod32 for a few years until it started conflicting with the new version of my backup software, which is essential for me. So then I tried Kaspersky, and it's good but it forces all internet traffic to go through it (as I can see through NetLimiter), which keeps breaking my downloads and giving me timeouts. So my question is: is there a good anti-virus i could use beside these two? I need it to be light and efficient. I'm not looking for free ones btw. Appreciate your input.

  Is there any essential difference between this code: ThreadStart starter = new ThreadStart(SomeMethod); starter.Invoke(); and this? ThreadStart starter = new ThreadStart(SomeMethod); Thread th = new Thread(starter); th.Start(); Or does the first invoke the method on the current thread while the second invokes it on a new thread?

• compTIA-AT EXAM

  - by SysPrep2010

  Hello everyone, I have been in the IT field only for two years. I have been dealing with servers, firewalls, routers, switches, backup servers, and desktop. For the desktop, i have been dealing with WDS (Window deployment services). Not a lot of hardware. My question is this, is it really important to have an AT cert under your belt. I dont see the point anymore. When a desktop goes down, what have been seeing, they just buy a new one. I mean I can rebuild systems they are fun, but I haven't in a while?

• Is there a way to create a consistent snapshot/SnapMirror across multiple volumes?

  - by Tomer Gabel

  We use a NetApp FAS 6-series filer with an application that spans multiple volumes. For backup purposes I would like to create a consistent snapshot that spans these volumes at the same point in time (or at least with an extremely low delta); additionally, we'd like to to use SnapMirror to replace the production environment to test volumes. The problem is in creating a consistent snapshot/SnapMirror, since these commands are not transactional and do not take multiple parameters. I tried scripting consecutive "snap create" or "snapmirror resync" commands via SSH, but there's always a 0.5-2 second difference between each snapshot. It's currently "good enough", but I'm seriously concerned about the consistency impact with increased load (we're currently in pre-production). Has anyone managed to create a consistent snapshot that spans several volumes? How did you pull it off?

• Linq to Entities and outer joins issue

  - by Robert Koritnik

  Can somebody tell me, why does Linq to Entities translate many to 1 relationships to left outer joins instead of inner joins? It relation was many to 0..1. There's referential constraint on DB itself, that ensures there's a record in the right table, so inner join should be used instead. Is it possible to write LINQ in a way so they will translate to inner joins rather than left outer joins. It would speed query execution a lot.
