• PASS Summit Location Redux

  - by andyleonard

  Introduction To quote Ronald Reagan, " There you go again ." The Professional Association for SQL Server (PASS) is considering locations for future PASS Summits. The apparent answer is: You Can Have The Summit Anywhere You Want... ... as long as it's in Seattle. PASS conducted a survey on this about a year ago, and I commented on the results and PASS' (mis-)interpretation of said results in a post entitled On PASS Summit Locations, Time Will Tell . "It's About Community" I think every member of the...(read more)

• How to migrate from Banshee to Rhythmbox?

  - by rafalcieslak

  As it has been decided, Ubuntu Precise 12.04 will feature Rhythmbox as the default music player. I am aware, that it does not mean that I will not be able to use Banshee, nevertheless I would like to switch to it. I have been a Rhythmbox fan for a long time, but after the switch to Banshee in Natty I decided to give it a try and completely migrated to it. However, I am not very happy with it, it lags for me a lot and has some other issues. I would like to export all Banshee data to Rhythmbox. That includes: Music library Playlists Preferably playcounts and ratings Radio stations Cover pictures What should I do to move all this data to Rhythmbox, get it to work as the default music player, and smoothly switch completely to it?

• SuperSocket

  - by csharp-source.net

  SuperSocket is a light weight extensible socket application framework. You can use it to build a command based server side socket application (like FTP server, SMTP/POP3/IMAP4 server, SIP server, etc) easily without thinking about how to use socket, how to maintain the socket connections and how socket works(synchronize/asynchronize). It is a pure C# project which is designed to be extended, so it is easy to be integrated to your existing system. As long as your systems (like forum/CRM/MIS/HRM/ERP) are developed in .NET language, you must be able to use SuperSocket to build your socket application as a part of your current system perfectly.

• Should you document everything or just most?

  - by TheLQ

  It seems a bit of a controversial subject to document everything, including the "JavaBean" syntax of getters and setters for fields: People say its needlessly long and repetitive breaking DRY (don't repeat yourself), that the naming convention should explain everything, and it clutters code/documentation. Sometimes those arguments work. But other times, you end up with this: Above is common to open source projects that do boldly follow those principles. Your left with entirely useless documentation. That doesn't explain anything about whats going on underneath, the possible effects, or even what the expected value is (could it be null or never null? I don't know, the Javadoc doesn't tell me). So when should I document? Do I document everything even if it occasionally clutters code? Or do I document nothing since in my eyes its "obvious"?

• How to recognize a good programmer?

  - by gius

  Our company is looking for new programmers. And here comes the problem - there are many developers who look really great at the interview, seem to know the technology you need and have a good job background, but after two moths of work, you find out that they are not able to work in a team, writing some code takes them very long time, and moreover, the result is not as good as it should be. So, do you use any formalized tests (are there any?)? How do you recognize a good programmer - and a good person? Are there any simple 'good' questions that might reveal the future problems? ...or is it just about your 'feeling' about the person (ie., mainly your experience), and trying him out? Edit: According to Manoj's answer, here is the question related to the coding task at the job interview.

• Un-used Indexes on MDP_MATRIX Consuming Resources

  - by user702295

  Disable un-used Indexes: As much as it is recommended to create relevant indexes, it is advised not to have too many indexes on the mdp_matrix table.  Too many indexes will cause long waits on the table as indexes needs to get updated every time the table is updated.  There are many seeded indexes on mdp_matrix, every out of the box data model level has an index on the matrix table.  If a level is unused in the specific data model of the implementation, it is advisable to disable that index.  If the customer is not sure if and how indexes are utilized, the DBA can monitor all indexes.  After a few cycles of operation, the DBA should go over that list and see which indexes have not been used.  Consider disabling them. There are scripts on the net to monitor indexes or use the monitoring usage clause in the alter index statement.

• What is a good robots.txt for WP ?

  - by Steven

  What is the "best" setup for robots.txt? I'm using the following permalink structure in Wordpress: /%category%/%postname%/. My robots.txt currently looks like this (copied from somewhere a long time ago): User-agent: * Disallow: /cgi-bin Disallow: /wp-admin Disallow: /wp-includes Disallow: /wp-content/plugins Disallow: /wp-content/cache Disallow: /wp-content/themes Disallow: /trackback Disallow: /comments Disallow: /category/*/* Disallow: */trackback Disallow: */comments I want my comments to be indext. So I can remove this, right? Do I want to disallow indexing categories because of my permalinkstructure? An article can have several tags and be in multiple categories. This may cause duplicates in google. How should I work around this? Would you change anything else here?

• What is the best wrapping strategy ?

  - by Riduidel

  Hi, I'm planning to integrate an external tool (ffmpeg in my particular case, but it could be anything, in fact, as lolng as its tasks are long running ones). This tool has a lot of command-line parameters. For now, I've done to simple things with it, already requiring me a good bunch of class writing, to embed all the information it can return to me. I now face the even more complex task of having to send it a bunch of parameters and to handle possible errors. So, what is a best way for that ? Create classes containing all possible options Relying upon a reverse equivalent of commons-cli / CliBuilder / OptionParser Directly write all options from user input Obiwan Kenobi powers (or anything I don't even know about) Please notice I do it in an uncommon language (for the sake of me, don't ask me what it is, as it looks like a desperate and sterile union between CoffeeScript and lua), as a consequence, there can be no framework doing what I want in the language I use.

• Delivering estimates and client expectations?

  - by FishOrDie

  When a client asks for an estimate on how long it would take to develop different sections of an app, is it best to give them a total amount or what it would take for each section? Is it better/more common to give a range of hours/days or just a single number? Do you think most clients feel that if a programmer says it should take 50 hours that they should be billed for 50 hours? If I say it would take 50 and it actually takes 60, do I tell them in advance that I'm going over on my estimate or just charge what was originally quoted?

• Desktop interface crashes after software updates

  - by N.C. Weber

  Recently, after installing Ubuntu software updates on the evening of December 7th, 2012, my desktop interface crashes regularly leaving me with a command line screen with a long string of automated commands showing (I assume what goes on behind the pretty desktop). At first, I thought it was only crashing whenever I played DirectX games in WINE, but now it crashes if I open the native Firefox browser or if it's doing nothing at all but sitting there. Apport attempts to report the bugs after restart, but often they crash as well. I've done a SMART check on the hard drive, and everything report OK. No read errors, no bad sectors. I am using an Acer Extensa 4620Z Memory: 2.0 GiB Processor: Intel Pentium Dual CPU T2370 @ 1.73GHz x 2 GraphicsL: Intel 965GM x86/MMX/SSE2 OS: Ubuntu 12.10 32-bit Disk: 116.0 GB with 33.4 GB Available

• Null Or Empty Coalescing

  In my last blog post, I wrote about the proper way to check for empty enumerations and proposed an IsNullOrEmpty method for collections which sparked a lot of discussion. This post covers a similar issue, but from a different angle. A very long time ago, I wrote about my love for the null coalescing operator. However, over time, Ive found it to be not quite as useful as it could be when dealing with strings. For example, heres the code I might want to write: public static void DoSomething(string...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Comprehensive system for documentation and handoff of developer project

  - by Uzumaki Naruto

  I work on a technology team that typically develops projects for a period of time, and then hands off to other groups for long-term maintenance and improvements. My team currently uses ad hoc methods of handing off documentations, such as diagrams, API references, etc. Is there a open source solution (or even proprietary one) that enables us to manage: Infrastructure/architecture/software diagrams API documentation Directory structures/file structures Overall documentation summaries in one place? E.g., instead of using multiple systems like Swagger, Wikis, etc. - is there a solution that can seamlessly combine all of these? And enable us to generate a package including all 4 key items with one click to hand off to other teams.

• Can I use remade sprites in my game?

  - by John Skridles

  Can I use remade sprites in my game? I am making a game and I used some sprites, but I didn't copy them. I remade them completely the character looks nothing like the original. I only did this to get the movement of the character right (moving, running, jumping, punching). I've been working on the game for a long time, so I really need to know is it safe and legal to do this. I do intend making a small profit.

• How to use short breaks at work effectively for self-development?

  - by Alaudo

  At the moment my daily work as a developer requires me to have short 10-20 min breaks after every 2-3 hours. It would be nice if I could use those effectively to improve my expertise in programming or CS in general. I tried several things: Reading jokes online gets boring very soon. Trying to solve some (even the most simple) tasks from different code contests requires more time, as long as I have some idea of an algorithm the time is over. Reading a randomly picked Wikipedia-article about Computer Science: depending upon the article sometimes it requires more time and is not an easy reading for a break. So, I ended up reading StackOverflow questions and answers with most votes: that is entertaining and educative. Do you have any other suggestions?

• Windows 8 keyboard shortcuts when virtualising OS X

  - by mbrit

  Seriously, I have no idea why this took me so long to actually sort out.So in Windows 8 you have new keyboard shortcuts for accessing search (Win+Q), charms (Win+C), settings (Win+I), etc. Problem is that some of those collide with standard OS X mapping - for example Win+Q will close down VMware, Win+C will issue copy, etc.You can add additional mappings into VMware. Use the Preferences panel to do that. Here you can see that I've mapped Win+Shift+C to Win+C. (OK, that assumes you use a Windows keyboard with a Mac, like I do. If you use a Mac keyboard, you're mapping Apple+Shift+C to Win+C.)

• Edit 100MB+ file

  - by Majid Fouladpour

  I have captured some traffic with Wireshark and saved the result as a file. The file has 3 sections now: request headers response headers response body The response body is to become an flv file, but now everything is saved as a single file. So I need a way to delete the first two sections from the file, but the problem is that the file is very big (over a thousand mega bytes). I have tried to open it with gedit, but no matter how long I wait, gedit hangs and remains unresponsive until I kill it. What tool can I use to edit this big file easily?

• Cursor (touchpad) moves and clicks erratically

  - by James Wood

  Sometimes (usually after two-finger scrolling) the touchpad on my Asus X54C becomes unresponsive and the cursor begins to click and move small distances. Clicking seems to happen more often than moving. Unlike with other similar problems, I've never seen the cursor move to (0, 0). Suspending (closing the lid) and unsuspending doesn't help, and neither does moving to a tty and back or rebooting. I've also tried disabling the touchpad via Fn+F9. That tends to take a long time, but doesn't have any effect. I'm on 13.10 at the moment, but I remember it happening on 13.04 as well. Here's the pointer section of xinput: ? Virtual core pointer id=2 [master pointer (3)] ? ? Virtual core XTEST pointer id=4 [slave pointer (2)] ? ? ETPS/2 Elantech Touchpad id=12 [slave pointer (2)]

• Why are some bugs I'm affected by and subscribed to missing in my launchpad bug list?

  - by joschi

  I have a long list of bugs in my launchpad account but some bugs I set to being affected by and being subscribed to are not showing up in that list. Even when I change the options of bugs to show I don't get these bugs.First I thought these were bugs being set to 'wishlist' but some of them are showing up in the list. Does anyone else know that he/she is subscribed to a bug he/she doesn't find in his bug list? And maybe there's also someone who knows how to fix this.

• Retail Link data storage requirements

  - by Randy Walker

  I was asked today about how much data an average Retail Link analyst (Walmart vendor) would consume.  I thought I would write this small post for future reference. Of course this vastly depends on the amount of skus, how long you want to archive data, and if you want store level sales. Most reports take up very little space. Most times when you download a report (total sales per sku for last week), you will overwrite the previous week’s report.  However, most users will take the data inside their downloaded report, and add it to a database or larger excel spreadsheet.  This way, the user has a history of the sales of each item/sku per week over the last 2+ years.  I would estimate 1 user to consume around 1-2 gb of space, at most, over the course of 2 years. If you start archiving store level sales those numbers can drastically increase up to 10gb or more very quickly.

• migrating from struts2, looking for a new framework

  - by adhg

  We are supposed to start a relatively big project that will require lots of computation and analysis. Presentation (UI) for the end user is very crucial (graphs, tabels...) So far we've been using struts2. It's ok+. It has some drawbacks (specially if you work with tiles and all that XML) but if you get the lingo - you're ok. One option on the table is to continue using struts2 with jquery and all the other stuff that we've been doing for so long. Alternatively, I think we have an opportunity to learn something new and maybe a bit better then struts2. My question is this: Anyone has migrated from struts2 to something new and can share the experience. Or had some great experience witha particular java framework. Many thanks for any pointers.

• Is the "One Description Table to rule them all" approch good?

  - by DavRob60

  Long ago, I worked (as a client) with a software which use a centralized table for it's codified element. Here, as far as I remember, how the table look like : Table_Name (PK) Field_Name (PK) Code (PK) Sort_Order Description So, instead of creating a table every time they need a codified field, they where just adding row in this table with the new Table_Name and Field_Name. I'm sometime tempted to use this pattern in some database I design, but I have resisted to this as from now, I think there's something wrong with this, but I cannot put the finger on it. It is just because you land with some of the structure logic within the Data or something else?

• Lenovo z470 getting hot, after 12.04 install

  - by Rodrigo

  When I was using Windows 7 my notebook temperature was very good, it stayed very cool. After I installed 12.04, my notebook base is hot all the time, I cannot even put my hands on it for a long time. My notebook has a 2nd generation Intel i5 processor. I installed Jupiter and it shows 72 Degrees Celsius constantly. Anyone got a fix for this? I don't want to go back to windows but if I do not find any solution I will have to do it. I'd be very grateful for any help.

• Should I forward the a call to .Equals onto .Equals<T>?

  - by Jaimal Chohan

  So, I've got you bog standard c# object, overriding Equalsand implementing IEquatable public override int GetHashCode() { return _name.GetHashCode(); } public override bool Equals(object obj) { return Equals(obj as Tag) } #region IEquatable<Tag> Members public bool Equals(Tag other) { if (other == null) return false; else return _name == other._name; } #endregion Now, for some reason, I used to think that forwarding the calls from Equals into Equals was bad, no idea why, perhaps I read it a long time ago, anyway I'd write separate (but logically same) code for each method. Now I think forwarding Equals to Equals is okay, for obvious reasons, but for the life me I can't remember why I thought it wasn't before. Any thoughts?

• Can you recommend a good tutorial on building custom package versions?

  - by Ivan

  After installing Ubuntu 11.04 I was disappointed by the fact there are still Scala 2.7 (when 2.8 is long ago current actual branch) and Mono 2.6 (when pretty a time has passed after 2.8 release). I am not sure I could build all the packages for Mono myself, but I'd like to try making my own custom version of Scala package (and I want my system to accept it not as a different package but a version of the original, so that if I put it into a configured repository, the system will automatically upgrade to it from currently installed original 2.7). Can you recommend a good tutorial on this subject (Ubuntu deb packages building and hacking for beginners)?
