• Create a Gallery With Drupal and Thickbox

  Powerful features and special effects are not something that only big websites with plenty of cash to burn can afford. In fact, most of the neat design features you see nowdays are pretty easy to get right - some with practically no programming required. Let's look at how to create a basic image gallery using Drupal, Views and Thickbox.

• Upgrades from Beta or CTP SQL Server Software is NOT Supported

  - by BuckWoody

  As of this writing, SQL Server 2008 R2 has released, and just like every release, I get e-mails and calls from folks with this question: “Can I upgrade from Customer Technical Preview (CTP) x or Beta #x or Release Candidate (RC) to the “Released to Manufacturing” (RTM) version?” No. Right up until the last minute, things are changing in the code – and you want that to happen. Our internal testing runs right up until the second we lock down for release, and we watch the CTP/RC/Beta reports to make sure there are no show-stoppers, and fix what we find. And it’s not just “big” changes you need to worry about – a simple change in one line of code can have a massive effect. I know, I know – you’ve possibly upgraded an RC or CTP to the RTM version and it worked “just fine”. But hear this tale: I’ve dealt with someone who faced this exact situation in SQL Server 2008. They upgraded (which is clearly prohibited in the documentation) from a CTP to the RTM version over a year ago. Everything was working fine. But then…one day they had an issue. Couldn’t fix it themselves, we took a look, days went by, and we finally had to call in the big guns for support. Turns out, the upgrade was the problem. So we had to come up with some elaborate schemes to get the system migrated over while they were in production. This was painful for everyone involved. So the answer is still no. Just don’t do it. There is one caveat to this story – if you are a “TAP” customer (you’ll know if you are), we help you move from the CTP products to RTM, but that’s a special case that we track carefully and send along special instructions and tools to help you along. That level of effort isn’t possible on a large scale, so it’s not just a magic tool that we run to upgrade from CTP to RTM. So again, unless you’re a TAP customer, it’s a no-no.

• Syncing apt-get installations between multiple computers

  - by Chris

  Is there a way to synchronize my installations (and removals) between multiple PCs? Preferably with dropbox - since I'm already using that to keep my files in sync. Edit: I thought of an alias for the apt-get install and apt-get remove commands that stores the parameters to a file (one for install, one for remove) and another command that reads all the entries in the file and executes the respective command. Is this an realistic approach?

• Identifying which pattern fits better.

  - by Daniel Grillo

  I'm developing a software to program a device. I have some commands like Reset, Read_Version, Read_memory, Write_memory, Erase_memory. Reset and Read_Version are fixed. They don't need parameters. Read_memory and Erase_memory need the same parameters that are Length and Address. Write_memory needs Lenght, Address and Data. For each command, I have the same steps in sequence, that are something like this sendCommand, waitForResponse, treatResponse. I'm having difficulty to identify which pattern should I use. Factory, Template Method, Strategy or other pattern. Edit I'll try to explain better taking in count the given comments and answers. I've already done this software and now I'm trying to refactoring it. I'm trying to use patterns, even if it is not necessary because I'm taking advantage of this little software to learn about some patterns. Despite I think that one (or more) pattern fits here and it could improve my code. When I want to read version of the software of my device, I don't have to assembly the command with parameters. It is fixed. So I have to send it. After wait for response. If there is a response, treat (or parse) it and returns. To read a portion of the memory (maximum of 256 bytes), I have to assembly the command using the parameters Len and Address. So I have to send it. After wait for response. If there is a response, treat (or parse) it and returns. To write a portion in the memory (maximum of 256 bytes), I have to assembly the command using the parameters Len, Address and Data. So I have to send it. After wait for response. If there is a response, treat (or parse) it and returns. I think that I could use Template Method because I have almost the same algorithm for all. But the problem is some commands are fixes, others have 2 or 3 parameters. I think that parameters should be passed on the constructor of the class. But each class will have a constructor overriding the abstract class constructor. Is this a problem for the template method? Should I use other pattern?

• Speaker Prep Tip: Use the AV Studio Built into that Laptop

  - by merrillaldrich

  Over at erinstellato.com there is a great post this week about tips for new presenters. Ms. Stellato suggests, insightfully, that we record ourselves, which is really a fantastic piece of advice. What’s extra-cool is that today you don’t need any special equipment or expensive software to do just that. This week I “filmed” two run-throughs of my talk for SQL Saturday tomorrow. For me, the timing is the hardest thing – figuring out how much content I can really present in the time allowed without...(read more)

• Can Adwords be cancelled by Google because of improper IE6 site rendering

  - by user745434

  A client just got a notice from Google saying that their Adwords campaign has been put on hold because the site is: Improperly rendering or Under constructions or Needs a special program to run Now the site is improperly rendering on IE6. On everything else, including IE7+ it's fine. If this is the issue, would putting up a "Looks like you're using an older browser" message instead of the site for IE6 be a solution? Or must the site look good in IE6 for the Adwords campaign to continue?

• Adding custom applications to Gnome launcher

  - by Shaftoe2702

  Looking for a utility that allows me insert an item into the list of applications that GNOME knows about. For example: I have downloaded Eclipse EE (I have some very special plugins that I need to work with, and those plugins don't "like" the version available in the default repository). I'm using GNOME 3, on Ubuntu 11.10. So I want to execute Eclipse w/o opening a terminal and running it. It must be something very simple.

• Why can't Java/C# implement RAII?

  - by mike30

  Question: Why can't Java/C# implement RAII? Clarification: I am aware the garbage collector is not deterministic. So with the current language features it is not possible for an object's Dispose() method to be called automatically on scope exit. But could such a deterministic feature be added? My understanding: I feel an implementation of RAII must satisfy two requirements: 1. The lifetime of a resource must be bound to a scope. 2. Implicit. The freeing of the resource must happen without an explicit statement by the programmer. Analogous to a garbage collector freeing memory without an explicit statement. The "implicitness" only needs to occur at point of use of the class. The class library creator must of course explicitly implement a destructor or Dispose() method. Java/C# satisfy point 1. In C# a resource implementing IDisposable can be bound to a "using" scope: void test() { using(Resource r = new Resource()) { r.foo(); }//resource released on scope exit } This does not satisfy point 2. The programmer must explicitly tie the object to a special "using" scope. Programmers can (and do) forget to explicitly tie the resource to a scope, creating a leak. In fact the "using" blocks are converted to try-finally-dispose() code by the compiler. It has the same explicit nature of the try-finally-dispose() pattern. Without an implicit release, the hook to a scope is syntactic sugar. void test() { //Programmer forgot (or was not aware of the need) to explicitly //bind Resource to a scope. Resource r = new Resource(); r.foo(); }//resource leaked!!! I think it is worth creating a language feature in Java/C# allowing special objects that are hooked to the stack via a smart-pointer. The feature would allow you to flag a class as scope-bound, so that it always is created with a hook to the stack. There could be a options for different for different types of smart pointers. class Resource - ScopeBound { /* class details */ void Dispose() { //free resource } } void test() { //class Resource was flagged as ScopeBound so the tie to the stack is implicit. Resource r = new Resource(); //r is a smart-pointer r.foo(); }//resource released on scope exit. I think implicitness is "worth it". Just as the implicitness of garbage collection is "worth it". Explicit using blocks are refreshing on the eyes, but offer no semantic advantage over try-finally-dispose(). Is it impractical to implement such a feature into the Java/C# languages? Could it be introduced without breaking old code?

• How can I get the touch screen working on a motion computing m1400

  - by pgcudahy

  I picked up a motion computing m1400 for cheap and was successful in getting 11.04 installed on it but have run into trouble getting the touch screen to work. This is one of the older tablet pcs that need a special pen for the touch screen. There are instructions out there for older versions of Ubuntu but they usually rely on a package called wacom-tools that is no longer in the repos. Is there any support for these old tablets or has time passed them by?

• Why the Indian link builders or SEO companies can make so many high quality links at the same time? [closed]

  - by chiba

  There are a lot of Indian SEO companies or link builders that offer a lot of high quality link. Some of them for example offer links just from "co.uk" or "French site" with high page ranks. I have heard that even the SEO companies from other countries outsource link building to India. Do they have special connections for building links ? or Do they exchange the information between another Indian companies and have a big database of the sites where they can link?

• Help understanding the migrate wubi documentation?

  - by user110259

  I'm looking at the MigrateWubi page but I'm not sure if I need to change the partition directories to the ones I created, and if so, I'm not too sure which ones I need to change. Here are the partitions I've made: Should I just copy and paste: sudo bash wubi-move.sh /dev/sda5 /dev/sda6 into my terminal or something else? Also, do I enter just this one line or do i need to enter any other commands in there? Thanks!

• What type of command can I use for shortcut assignment?

  - by navie

  We all know that Ubuntu 12 has a shortcut mapper under "Keyboard" utility. I wonder when it asks for "command" in the new shortcut dialog, what type of command can I use? I used to think that commands in terminal can also be used here, but it seems xdotool is not like that. btw, if xdotool is not the right solution, how to map a key combination to a another key? for e.g.: alt+j to Down arrow key Thank you

• Why do password strength requirements exist? [migrated]

  - by Bozho

  Password strength is now everything, and they force you to come up with passwords with digits, special characters, upper-case letters and whatnot. Apart from being a usability nightmare (even I as a developer hate it when a website requires a complex password), what are the actual benefits of having strong passwords (for website authentication)? Here are the prerequisites of a system that handles authentication properly: store passwords using bcrypt (or at least use salt+hash) - hard-to-impossible to find the original password when an attacker gets the database lock subsequent password attempts with a growing cooldown - no brute-force via the site
