• HP Pavilion tx2000 - Wifi adapter no longer works after moving from 12.04 to a 12.10 clean install

  - by Marek L.

  I have a HP Pavilion tx2000 that I have been running Ubuntu 12.04 on for a couple of months without any problems (wifi worked great) until yesterday when my hard drive failed. I replaced the hard drive and decided to install Ubuntu 12.10. Unlike 12.04, the wifi did not work after the installation finished and all the updates where installed (over Ethernet). The network drop down in the top right didn't even show a wireless option. I Googled about for a bit and found some solutions that seemed like they might work. Unfortunately they did not. Here is what I tried: sudo apt-get remove bcmwl-kernel-source sudo apt-get install b43-fwcutter sudo apt-get install firmware-b43-lpphy-installer Restart the computer. And the wifi still didn't work. At which point I panicked a bit and tried to undo the previous commands by running: sudo apt-get remove b43-fwcutter firmware-b43-lpphy-installer sudo apt-get install bcmwl-kernel-source Restart the computer. The wifi still doesn't work. This is where I stopped because I have no idea what I am doing and don't want to mess something up. The network drop down still doesn't show a wireless option and the hardware wifi switch on the laptop is amber (it turns blue when the wifi is on). Using the hardware switch does not change the color. Output from: sudo lspci ... 08:00.0 Network controller: Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller (rev 01) ...

Pushing the hardware switch turns the hard block back on and I have to run sudo rfkill unblock all multiple times again to turn it off. Any help is appreciated!

• Developing a php system that tracks other websites analytics

  - by CodeCrack

  I want to develop a PHP website feature where users sign up, get a javascript snippet code that display an image on their site, and let's me track the number of visitors, unique hits, clicks and average visitor duration on their page. Is that something that should be done with some open source analytic software such as http://piwik.org/ or it's pretty doable on your own? If I had to do it myself from scratch, I would use image/pixel as a way to track the visit, drop a cookie with javascript snippet to track uniques, track clicks based on image click and redirect, and not sure about the bounce rate. Any thoughts or opinions are welcome.

• Mouse buttons and all keyboard buttons except alt and super randomly stops working

  - by bobbaluba

  A couple of times lately, unity appears to not accept button presses from neither the mouse or the keyboard. This happens after a random amount of time, usually a couple of hours, or right after boot. The weird thing is: I can still move the mouse around. I can press alt to get the unity menu thingy (but i can't type anything in it) I can press super to show/hide the unity search. None of the applications seem to get the input Ive tried connecting a second mouse, same issue I can press ctrl+alt+f1 to drop to a shell tty The shell works fine Now, this is definitely a bug, probably in unity(?), but it's hard to search for when I don't know what's causing it. Is there something I can do to debug? I've found some people that appears to be having the same problem with the mouse only, but most of the time, their questions are unanswered or closed for being too specific. What would be a good strategy to fix this? Should I report it as a bug?

• Unity doesn't autostart on second X screen

  - by Nonoo

  I have two Nvidia cards both with 2 heads and both configured as TwinView, so I have Screen0 and Screen1 in my xorg.conf. ccsm sees both screens (displays them in the Screens drop-down at the top left), but Unity starts only on Screen0 by default. The displays on Screen1 only show the default white screen and default X mouse cursor, when I hover over them. Is this the normal, expected behavior? Can I start Unity on Screen1 automatically without running custom shell scripts (like DISPLAY=:0.1 compiz --replace)?

• XNA: Auto-populate content within the content project based on current folder/file structure and content management for large games

  - by Joe

  1) Is it possible to implement a system where I can simply drop a new image into my content project's folder and VS will automatically see that and bring it into the project for compiling? 2) Similarly, if I wanted a specific texture I could state something like var texture = Game.Assets.Image["backgrounds/sky_02"]; (where Game is the standard XNA Game class and Assets is some kind of content manager statically defined within Game). I know this is fairly simple to implement manually and have done such things in the past (static Dictionary defined within Game) except this only works for relatively small games where you can have all assets loaded at the start without much issue. How would you go about making this work for games where content is loaded and unloaded based on level / area? I'm not asking for the solution, just how you would go about this and what things you would have to be aware of. Thanks.

• Asciifi Is a Lightening Fast Web-Based ASCII Converter

  - by Jason Fitzpatrick

  If you have a hankering from some old-school ASCII artwork, Asciifi is a free and lightening fast HTML5 ASCII converter. Despite the simplicity of ASCII images (pictures created not out of a grid of colored pixels like a standard digital photograph but out of a grid of text characters) many ASCII converters are rather slow. Asciifi speeds up the process by rendering your images on the fly with a snappy HTML5-based converter. Visit the site, drag and drop your image, and almost instantaneously you’ll see the results. The output can be further tweaked by adjusting the line width and the character set used. Hit up the link below to take it for a test drive.

• How does a search functionality fit in DDD with CQRS?

  - by Songo

  In Vaughn Vernon's book Implementing domain driven design and the accompanying sample application I found that he implemented a CQRS approach to the iddd_collaboration bounded context. He presents the following classes in the application service layer: CalendarApplicationService.java CalendarEntryApplicationService.java CalendarEntryQueryService.java CalendarQueryService.java I'm interested to know if an application will have a search page that feature numerous drop downs and check boxes with a smart text box to match different search patterns; How will you structure all that search logic? In a command service or a query service? Taking a look at the CalendarQueryService.java I can see that it has 2 methods for a huge query, but no logic at all to mix and match any search filters for example. I've heard that the application layer shouldn't have any business logic, so where will I construct my dynamic query? or maybe just clutter everything in the Query service?

• Copy all bridge traffic to a specific interface

  - by Azendale

  I have a bridge/switch set up an a machine that has multiple ports. Occasionally, I have a vm running through virtualbox, and I'll have it use a virtual adapter and then I add the adapter to the bridge. I have heard that some switches can copy all the traffic they see to a specific port on the bridge, usually for network monitoring. I would like to be able to run some windows based network tools. I do not want to run Windows on the actual hardware, because it would be lots of work to duplicate my setup in windows, so I was thinking if I can copy all traffic to a port, I can send it to a VM with windows. How can I set this up? I think this might be ebtables area, but I don't know ebtables well enough to know for sure, and it always seems like (from my understanding of ebtables) ebtables does something with the traffic (drop, accept, etc), but never copies it.

• Replace Libre Office with Microsoft Office

  - by user26272

  folks. I finally convinced my sister to drop Windows at her small business and go Ubuntu. She complained, though, that she does not want to use Libre Office and is willing to use Microsoft Office instead. I was like, ok, then. Then, she asked: - Libre office is the default, right? - Right. - So, if someone gives me a document, by default it will open on Libre Office. Can you make it open on Microsoft Office by default instead? So, even if I get it working via Wine, can I do what she requested or is it an impossible task?

• Display in applications on ubuntu 12.10 is broken - maybe theme problem

  - by Aleksandar

  I have a problem which looks like this: http://s16.postimage.org/yjusy9en9/Screenshot_from_2012_10_28_22_49_07.png If you take a look at buttons "Apply", "Reset", "Close" or any other buttons or drop-downs, you will see there is no style on them. It is a fresh install of ubuntu 12.10 and it was working on the beginning. But after some time setting up ubuntu I noticed the style on the elements has gone - I don't know when. I installed compiz-settings - maybe that caused - but when I un-install nothing changes. Also checking/unchecking "window decoration" in compiz doesn't help. Please help me. I am out of options :/

• SQL SERVER – Weekly Series – Memory Lane – #004

  - by pinaldave

  Here is the list of curetted articles of SQLAuthority.com across all these years. Instead of just listing all the articles I have selected a few of my most favorite articles and have listed them here with additional notes below it. Let me know which one of the following is your favorite article from memory lane. 2006 Auto Generate Script to Delete Deprecated Fields in Current Database In early career everytime I have to drop a column, I had hard time doing it because I was scared what if that column was needed somewhere in the code. Due to this fear I never dropped any column. I just renamed the column. If the column which I renamed was needed afterwards it was very easy to rename it back again. However, it is not recommended to keep the deleted column renamed in the database. At every interval I used to drop the columns which was prefixed with specific word. This script is 6 years old but still works. Give it a look, I am open for improvements. 2007 Shrinking Truncate Log File – Log Full – Part 2 Shrinking database or mdf file is indeed bad thing and it creates lots of problems. However, once in a while there is legit requirement to shrink the log file – a very rare one. In the rare occasion shrinking or truncating the log file may be the only solution. However, one should make sure to take backup before and after the truncate or shrink as in case of a disaster they can be very useful. Remember that truncating log file will break the log chain and while restore it can create major issue. Anyway, use this feature with caution. 2008 Simple Use of Cursor to Print All Stored Procedures of Database Including Schema This is a very interesting requirement I used to face in my early career days, I needed to print all the Stored procedures of my database. Interesting enough I had written a cursor to do so. Today when I look back at this stored procedure, I believe there will be a much cleaner way to do the same task, however, I still use this SP quite often when I have to document all the stored procedures of my database. Interesting Observation about Order of Resultset without ORDER BY In industry many developers avoid using ORDER BY clause to display the result in particular order thinking that Index is enforcing the order. In this interesting example, I demonstrate that without using ORDER BY, same table and similar query can return different results. Query optimizer always returns results using any method which is optimized for performance. The learning is There is no order unless ORDER BY is used. 2009 Size of Index Table – A Puzzle to Find Index Size for Each Index on Table I asked this puzzle earlier where I asked how to find the Index size for each of the tables. The puzzle was very well received and lots of interesting answers were received. To answer this question I have written following blog posts. I suggest this weekend you try to solve this problem and see if you can come up with a better solution. If not, well here are the solutions. Solution 1 | Solution 2 | Solution 3 Understanding Table Hints with Examples Hints are options and strong suggestions specified for enforcement by the SQL Server query processor on DML statements. The hints override any execution plan the query optimizer might select for a query. The SQL Server Query optimizer is a very smart tool and it makes a better selection of execution plan. Suggesting hints to the Query Optimizer should be attempted when absolutely necessary and by experienced developers who know exactly what they are doing (or in development as a way to experiment and learn). Interesting Observation – TOP 100 PERCENT and ORDER BY I have seen developers and DBAs using TOP very causally when they have to use the ORDER BY clause. Theoretically, there is no need of ORDER BY in the view at all. All the ordering should be done outside the view and view should just have the SELECT statement in it. It was quite common that to save this extra typing by including ordering inside of the view. At several instances developers want a complete resultset and for the same they include TOP 100 PERCENT along with ORDER BY, assuming that this will simulate the SELECT statement with ORDER BY. 2010 SQLPASS Nov 8-11, 2010-Seattle – An Alternative Look at Experience In year 2010 I attended most prestigious SQL Server event SQLPASS between Nov 8-11, 2010 at Seattle. I have only one expression for the event - Best Summit Ever. Instead of writing about my usual routine or the event, I wrote about the interesting things I did and how I felt about it! When I go back and read it, I feel that this is the best event I attended in year 2010. Change Database Access to Single User Mode Using SSMS Image says all. 2011 SQL Server 2012 has introduced new analytic functions. These functions were long awaited and I am glad that they are now here. Before when any of this function was needed, people used to write long T-SQL code to simulate these functions. But now there’s no need of doing so. Having available native function also helps performance as well readability.

• Smartassembly 5: it lives! Early Access builds now available

  - by Bart Read

  I'm pleased to announce that, late last week, we put out the first early access build for Smartassembly 5, Red Gate's fantastic code protection and error reporting tool, which we acquired last September. You can download it via: http://www.red-gate.com/messageboard/viewforum.php?f=116 It's obviously pretty early days, so please do not try to use this to protect a production application, but we've already done a lot of work in some key areas: We're simplifying and streamlining the licensing model (you won't see this yet, but a lot of the work on this has already been done). We've improved usability of the product, with a better menu, reordering of project settings, and better defaults. We've also fixed a load of bugs, which I'll let Alex blog about in more detail. On a slightly more trivial level, the curly braces are also no more. Over the coming weeks, we'll be adding more improvements, and starting usability tests. If you're interested in getting involved in the latter, please drop an email to [email protected].

• Is making my own copyright licence safe?

  - by abcd

  I've seen various open source libraries (actually I've seen it for assets as well) having a home-baked license in the following manner : SomeGuy's License:1. You can use this code freely in commercial projects and modify it as you wish, but not sell it2. If you want to sell a modified version, drop me an email first, or give credits to me Edit: The above example is ambiguous, so I am giving another one, I want to know if 3 lines of license will hold some ground: SomeGuy's License:1. You can use this code in a commercial project as a 3rd party library2. You can't sell it as a derivative work I know that such license is not polished at all, for example the Creative Commons set of licenses seem to be short, but actually have some large legal stuff underneath it, but I wonder if at least some level of protection can be gained with a hobby license like that ? My question is, could this hold any ground in the court, or would the corporative lawyers of the company X tear it apart ?

• Making a Background Scrolling in Stacking Game

  - by David Dimalanta

  Hmmm...Is it a good idea to use a LibGDX parallax background for making a stacking game (i.e. PAPA STACKer Lite)? For example, I'm starting to use the blocks to drag-n-drop it. Next, when the next piece reaches the top of the screen, it automatically scrolls to the next one where the available space left. Aside from that, is it also involved with the camera code (Orthographic Camera) that the screen size appeared like 720x1280 but actually it's 1440x2560 for example? And another thing, does the background scrolling have the option to scroll from start to finish and infinite?

• Why does Clang/LLVM warn me about using default in a switch statement where all enumerated cases are covered?

  - by Thomas Catterall

  Consider the following enum and switch statement: typedef enum { MaskValueUno, MaskValueDos } testingMask; void myFunction(testingMask theMask) { switch theMask { case MaskValueUno: {}// deal with it case MaskValueDos: {}// deal with it default: {} //deal with an unexpected or uninitialized value } }; I'm an Objective-C programmer, but I've written this in pure C for a wider audience. Clang/LLVM 4.1 with -Weverything warns me at the default line: Default label in switch which covers all enumeration values Now, I can sort of see why this is there: in a perfect world, the only values entering in the argument theMask would be in the enum, so no default is necessary. But what if some hack comes along and throws an uninitialized int into my beautiful function? My function will be provided as a drop in library, and I have no control over what could go in there. Using default is a very neat way of handling this. Why do the LLVM gods deem this behaviour unworthy of their infernal device? Should I be preceding this by an if statement to check the argument?

• What would you do if your client required you not to use object-oriented programming?

  - by gunbuster363

  Would you try to persuade your client that using object-oriented programming is much cleaner? Or would you try to follow what he required and give him crappy code? Now I am writing a program to simulate the activity of ants in a grid. The ant can move around, pick up things and drop things. The problem is while the action of the ants and the positions of each ant can be tracked by class attributes easily (and we can easily create many instances of such ants) my client said that since he has a background in functional programming he would like the simulation to be made using functional programming. What would you do?

• SQL SERVER – ?Finding Out What Changed in a Deleted Database – Notes from the Field #041

  - by Pinal Dave

  [Note from Pinal]: This is a 41th episode of Notes from the Field series. The real world is full of challenges. When we are reading theory or book, we sometimes do not realize how real world reacts works and that is why we have the series notes from the field, which is extremely popular with developers and DBA. Let us talk about interesting problem of how to figure out what has changed in the DELETED database. Well, you think I am just throwing the words but in reality this kind of problems are making our DBA’s life interesting and in this blog post we have amazing story from Brian Kelley about the same subject. In this episode of the Notes from the Field series database expert Brian Kelley explains a how to find out what has changed in deleted database. Read the experience of Brian in his own words. Sometimes, one of the hardest questions to answer is, “What changed?” A similar question is, “Did anything change other than what we expected to change?” The First Place to Check – Schema Changes History Report: Pinal has recently written on the Schema Changes History report and its requirement for the Default Trace to be enabled. This is always the first place I look when I am trying to answer these questions. There are a couple of obvious limitations with the Schema Changes History report. First, while it reports what changed, when it changed, and who changed it, other than the base DDL operation (CREATE, ALTER, DELETE), it does not present what the changes actually were. This is not something covered by the default trace. Second, the default trace has a fixed size. When it hits that size, the changes begin to overwrite. As a result, if you wait too long, especially on a busy database server, you may find your changes rolled off. But the Database Has Been Deleted! Pinal cited another issue, and that’s the inability to run the Schema Changes History report if the database has been dropped. Thankfully, all is not lost. One thing to remember is that the Schema Changes History report is ultimately driven by the Default Trace. As you may have guess, it’s a trace, like any other database trace. And the Default Trace does write to disk. The trace files are written to the defined LOG directory for that SQL Server instance and have a prefix of log_: Therefore, you can read the trace files like any other. Tip: Copy the files to a working directory. Otherwise, you may occasionally receive a file in use error. With the Default Trace files, if you ask the question early enough, you can see the information for a deleted database just the same as any other database. Testing with a Deleted Database: Here’s a short script that will create a database, create a schema, create an object, and then drop the database. Without the database, you can’t do a standard Schema Changes History report. CREATE DATABASE DeleteMe; GO USE DeleteMe; GO CREATE SCHEMA Test AUTHORIZATION dbo; GO CREATE TABLE Test.Foo (FooID INT); GO USE MASTER; GO DROP DATABASE DeleteMe; GO This sets up the perfect situation where we can’t retrieve the information using the Schema Changes History report but where it’s still available. Finding the Information: I’ve sorted the columns so I can see the Event Subclass, the Start Time, the Database Name, the Object Name, and the Object Type at the front, but otherwise, I’m just looking at the trace files using SQL Profiler. As you can see, the information is definitely there: Therefore, even in the case of a dropped/deleted database, you can still determine who did what and when. You can even determine who dropped the database (loginame is captured). The key is to get the default trace files in a timely manner in order to extract the information.
