• Full Circle

  - by capgpilk

  Things have been a little bit hectic these past 6 months hence the lack of posts. My excuse is a good one though, my wife gave birth to our first son Tom back in September and it has been one hell of a rollercoaster ride since then. Things have settled back down now thank hevens.My last development gig didn't quite work out so now I have took the plunge and started contracting. It turns out my first contract is with the NHS trust that I started my development career with, which seems a bit wierd as that was 10 years ago. A lot has changed in the techniques and tools the NHS now use to develop with, there is a lot more .net with a slant towards the web side of the spectrum (at least in this NHS trust). They are really getting to grips with the MVC platform, so you will hopefully see some MVC posts coming up. The really suprising thing is that the Intranet I developed back in 2001 (classic asp migrated to .net 1.0) is still up and running and will finally be fazed out these coming weeks (to Sharepoint). It is like seeing an old friend all grown up.

• Acceptable sound quality: stereo needed for an Android game?

  - by Thomas Calc

  I have various simple short sound effects (damage sound, dying sound, thunderbolt, fanfare, breaking) for a game that is developed for Android currently. I use OGG files: 96kbps VBR, 44.1KHz, 2 channels (that means stereo, right?). I read the other stackexchange topics about "acceptable sound quality", but they're too general, address too many things. My experience is that even with 80kbps, my effects sound OK. But I tested it on a limited number of Android devices (including a Sony Ericsson Xperia Neo and a HTC Desire HD). My questions: For mobile phones and tablets, generally, what parameters are recommended? Won't my 80kbps sounds be bad on a newer device (such as a modern tablet)? I don't hear any difference between stereo and mono (2 channels vs. 1 channel, right?), is there any noticeable difference at all for mobile phones / tablets? (in terms of the player experience) May it worth it at all? I assume that stereo sounds take much more in memory (when they're decoded to PCM), despite of the fact that the compressed OGG size is practically the same. Reacting to Roy T.'s great comment: Actually, I couldn't measure the PCM size (Android decodes OGG internally), but I thought that stereo will take more space than mono when uncompressed After throwing out one of the WAV channels in Audacity, and re-exporting it: The new WAV file size is half than before The OGG file size is practically the same as before The sound effects and game music was recorded by my friend who is an experienced hobby musician/composer, but he knows little about computers & software so he just gave me some high-quality WAV files generated via his hardware.These were stereo, but if I check them in Audacity, both channels appear to be exactly the same.Can I consider them the same (= moving to mono), or might there be some unnoticeable differences to the human eye?

• SQL Rally Pre-Con: Data Warehouse Modeling – Making the Right Choices

  - by Davide Mauri

  As you may have already learned from my old post or Adam’s or Kalen’s posts, there will be two SQL Rally in North Europe. In the Stockholm SQL Rally, with my friend Thomas Kejser, I’ll be delivering a pre-con on Data Warehouse Modeling: Data warehouses play a central role in any BI solution. It's the back end upon which everything in years to come will be created. For this reason, it must be rock solid and yet flexible at the same time. To develop such a data warehouse, you must have a clear idea of its architecture, a thorough understanding of the concepts of Measures and Dimensions, and a proven engineered way to build it so that quality and stability can go hand-in-hand with cost reduction and scalability. In this workshop, Thomas Kejser and Davide Mauri will share all the information they learned since they started working with data warehouses, giving you the guidance and tips you need to start your BI project in the best way possible?avoiding errors, making implementation effective and efficient, paving the way for a winning Agile approach, and helping you define how your team should work so that your BI solution will stand the test of time. You'll learn: Data warehouse architecture and justification Agile methodology Dimensional modeling, including Kimball vs. Inmon, SCD1/SCD2/SCD3, Junk and Degenerate Dimensions, and Huge Dimensions Best practices, naming conventions, and lessons learned Loading the data warehouse, including loading Dimensions, loading Facts (Full Load, Incremental Load, Partitioned Load) Data warehouses and Big Data (Hadoop) Unit testing Tracking historical changes and managing large sizes With all the Self-Service BI hype, Data Warehouse is become more and more central every day, since if everyone will be able to analyze data using self-service tools, it’s better for him/her to rely on correct, uniform and coherent data. Already 50 people registered from the workshop and seats are limited so don’t miss this unique opportunity to attend to this workshop that is really a unique combination of years and years of experience! http://www.sqlpass.org/sqlrally/2013/nordic/Agenda/PreconferenceSeminars.aspx See you there!

• Computer Bugs - Etymology and Entomology

  - by PointsToShare

  Whatever bugs you My wife and I used to take some of our summer vacation I a cabin on the shore of Lake Atsion in NJ. I t is a delightful place in the Wharton forest with Brown yet fresh water, where we would canoe, swim and enjoy true rest. Alas, in the last few years, yellow flies also discovered the area’s pastoral delights and came in hoards to bug us. So much so that we had to give up. As a computer programmer I abhor bugs. The bugs that bug me – except the pesky yellow flies – are program bugs , a specific variety of computer bugs. You can find an excellent take on the etymology of the word ‘bug” in this delightful monogram: http://www.jamesshuggins.com/h/tek1/first_computer_bug.htm In my youth, I worked on Burroughs computers. Unlike their IBM brethren, the Burroughs used a 96 column card. The cards were much smaller than the 80 column IBM cards. We wrote our programs on coding sheets and then a key-punch operator transcribed them into punched cards. These were fed into a card reader and compiled. The compiler would notify us of compiler errors or bugs, but it was not always easy to get the meaning of the message. My friend Mark Wildt, also a Burroughs veteran, gave me an old punched card from one of his programs. Obviously a bug!! Here It Is!! That’s All Folks!

• Where to find Hg/Git technical support?

  - by Rook

  Posting this as a kind of a favour for a former coleague, so I don't know the exact circumstances, but I'll try to provide as much info as I can ... A friend from my old place of employment (maritime research institute; half government/commercial funding) has asked me if I could find out who provides technical support (commercial) for two major DVCS's of today - Git and Mercurial. They have been using VCS for years now (Subversion while I was there, don't know what they're using now - probably the same), and now they're renewing their software licences (they have to give a plan some time in advance for everything ... then it goes "through the system") and although they will be keeping Subversion as well, they would like to justify beginning of DVCS as an alternative system (most people root for Mercurial since it seems simpler; mostly engineers and physicians there who are not that interested in checking Git repos for corruption and the finer workings of Git, but I believe any one of the two could "pass") - but it has to have a price (can be zero; no problem there) and some sort of official technical support. It is a pro forma matter, but it has to be specified. Most of the people there are using one of the two already, but this has to be specified to be official. So, I'm asking you - do you know where could one go for Git or Mercurial technical support (can be commercial)? Technical forums and the like are out of the question. It has to work on the principle: - I have a problem. - I post a question with the details. - I get an answer in specified time. It can be "we cannot do that." but it has to be an official answer and given in agreed time. I'm sure by now most of you understand what I'm asking, but if not - post a comment or similar. Also, if you think of any reasons which could decide justification of introducing Git/Hg from an technical and administrative viewpoint, feel free to write them down also.

• Is taking a semester or year off from college a good idea?

  - by astrieanna

  I am currently a Junior majoring in Computer Science at a top university (in the USA). As I'm really getting tired of taking classes, I was wondering if taking a semester or year off to do an internship(s) is a reasonable idea? It seems like it would give me more experience programming (making classes a bit easier), and give me a chance to recover from the burnout that comes from taking 18 credits a semester. A friend suggested that I just take a lighter course load, but I only have 2 more semesters of financial aid, so I need to take 18 credits in each of them in order to finish. Taking time off from school is not a normal thing to do, at least at this school. Since more internships are advertised for the summer (that I've seen), I was wondering if there are internships available in times other than the summer? If I took off for a whole year, would it be more valuable to try to stay at the same company for the whole time or to try to get a series of internships at different ones? Valuable in both the sense of resume value and personal value. Would it be easier or harder to get multiple shorter internships?

• Performance issues with visibility detection and object transparency

  - by maul

  I'm working on a 3d game that has a view similar to classic isometric games (diablo, etc.). One of the things I'm trying to implement is the effect of turning walls transparent when the player walks behind them. By itself this is not a huge issue, but I'm having trouble determining which walls should be transparent exactly. I can't use a circle or square mask. There are a lot of cases where the wall piece at the same (relative) position has different visibility depending on the surrounding area. With the help of a friend I came up with this algorithm: Create a grid around the player that contains a lot of "visibility points" (my game is semi tile-based so I create one point for every tile on the grid) - the size of the square's side is close to the radius where I make objects transparent. I found 6x6 to be a good value, so that's 36 visibility points total. For every visibility point on the grid, check if that point is in the player's line of sight. For every visibility point that is in the LOS, cast a ray from the camera to that point and mark all objects the ray hits as transparent. This algorithm works - not perfectly, but only requires some tuning - however this is very slow. As you can see, it requries 36 ray casts minimum, but most of the time 60-70 depending on the position. That's simply too much for the CPU. Is there a better way to do this? I'm using Unity 3D but I'm not looking for an engine-specific solution.

• Hallmarks of a Professional PHP Programmer

  - by Scotty C.

  I'm a 19 year old student who really REALLY enjoys programming, and I'm hoping to glean from your years of experience here. At present, I'm studying PHP every chance I get, and have been for about 3 years, although I've never taken any formal classes. I'd love to some day be a programmer full time, and make a good career of it. My question to you is this: What do you consider to be the hallmarks or traits of a professional programmer? Mainly in the field of PHP, but other, more generalized qualifications are also more than welcome, as I think PHP is more of a hobbyist language and may not be the language of choice in the eyes of potential employers. Please correct me if I'm wrong. Above all, I don't want to wast time on something that isn't worth while. I'm currently feeling pretty confident in my knowledge of PHP as a language, and I know that I could build just about anything I need and have it "work", but I feel sorely lacking in design concepts and code structure. I can even write object oriented code, but in my personal opinion, that isn't worth a hill of beans if it isn't organized well. For this reason, I bought Matt Zandstra's book "PHP Objects, Patterns, and Practice" and have been reading that a little every day. Anyway, I'm starting to digress a little here, so back to the original question. What advice would you give to an aspiring programmer who wants to make an impact in this field? Also, on a side note, I've been working on a project with a friend of mine that would give a fairly good idea of where I'm at coding wise. I'm gonna give a link, I don't want anyone to feel as though I'm pushing or spamming here, so don't click it if you don't want to. But if you are interested on giving some feedback there as well, you can see the code on github. I'm known as The Craw there. https://github.com/PureChat/PureChat--Beta-/tree/

• SharePoint 2010 and Windows Server Backup

  - by Enrique Lima

  A couple of months ago, a friend found a bit of information on TechNet that has proven to be quite useful. See, I am of the opinion SharePoint allows for smaller deployments to be made, and with that said, I am talking about SharePoint Foundation 2010 being used for the most part. But truly the point here is not to discuss whether or not a deployment of SharePoint Foundation 2010 or SharePoint Server 2010 is right or not.  The fact is they do take place and happen.  And information will reside there. Now, the point of this post is to raise awareness on options available for companies that have implemented it and maybe are a bit “iffy” on how to protect the information being placed in libraries and lists.  In many cases I have found SharePoint comes first and business continuity becomes an afterthought.  The documentation piece from TechNet states: “You can register SharePoint Server 2010 with Windows Server Backup by using the stsadm.exe -o -registerwsswriter operation to configure the Volume Shadow Copy Service (VSS) writer for SharePoint Server. Windows Server Backup then includes SharePoint Server 2010 in server-wide backups. When you restore from a Windows Server backup, you can select Microsoft SharePoint Foundation (no matter which version of SharePoint 2010 Products is installed), and all components reported by the VSS writer forSharePoint Server 2010 on that server at the time of the backup will be restored. Windows Server Backup is recommended only for use with for single-server deployments.” Even in the event of single-server deployments you will have options to safeguard your data. The process will require that after you have executed the stsadm command above, you will then use Windows Server Backup to do a Full Server Backup.  Then when the restore operation is needed you will be able to select specifically the section that has the SharePoint technologies backup. The restore process: Hope you find this to be a helpful post.  I have found this to be specially handy in SharePoint deployments that are part of a Team Foundation Server deployment and that are isolated from any other SharePoint farm and such.   Credits:  Sean McDonough for passing along the information available on TechNet.

• Edd strikes again &ndash; IronRuby for Rubyists on InfoQ

  - by Eric Nelson

  Colleague, friend and generally top guy on IronRuby Edd Morgan has just been published over on InfoQ. To wet the appetite… a snippet or three. IronRuby for Rubyists IronRuby is Microsoft's implementation of the Ruby language we all know and love with the added bonus of interoperability with the .NET framework — the Iron in the name is actually an acronym for 'Implementation running on .NET'. It's supported by the .NET Common Language Runtime as well as, albeit unofficially, the Mono project. You'd be forgiven for harbouring some question in your mind about running a dynamic language such as Ruby atop the CLR - that's where the DLR (Dynamic Language Runtime) comes in. The DLR is Microsoft's way of providing dynamic language capability on top of the CLR. Both IronRuby and the DLR are, as part of Microsoft's commitment to open source software, available as part of the Microsoft Public License on GitHub and CodePlex respectively… And Metaprogramming with IronRuby The art and science of metaprogramming — especially in Ruby, where it's an absolute joy — is something that could very easily span an entire article. As you would hope, IronRuby code is fully able to manipulate itself allowing you to bend your classes to your whim just as you would expect with a good dynamic language… And Riding the irails? So let's get to the point. I think it's a solid bet to make that a large proportion of Ruby programmers are familiar with the Rails framework - perhaps it's even safe to assume that most were first led to the Ruby language by the siren song of the Rails framework itself. Long story short, IronRuby is compatible enough to run your Rails app… Now… get yourself over to the full article and also check out some of Edds other work below.

• Koans, now available in Python flavor

  - by Greg Malcolm

  Recently a Python developer friend with whom I was pair programming with suggested that I show him how to write a little Ruby. I responded by telling him to check out Ruby Koans as a starting point. However I wanted to try that in reverse at the same time with me learning some Python. I did a bit of googling, and sure enough someone had started writing some Python Koans. It just needed finishing... So, a few weeks later Python Koans is now complete and ready for action! It is available through Mercurial on Bitbucket: http://bitbucket.org/gregmalcolm/python_koans/wiki/Home It is also mirrored on Github: http://wiki.github.com/gregmalcolm/python_koans/ Converting it was fairly easy. Aside from the differing philosophical approaches behind the two languages, Ruby and Python are fairly similar. We had to come up with completely new material for a few subjects like multiple inheritance and decorators, but for most features in Ruby there is something roughly comparable in Python. I highly recommend writing tests (or koans) as a means to lean a new language or framework. I've learned a lot from doing this.

• Suggested Resources Visual Studio Plug-In

  Todays post is a quick plug for a new tool developed by my friend Olaf Conijn, who (amongst other things) has been a developer on several versions of Enterprise Library. His new tool is called Suggested Resources for .NET Developers, and the current 0.8 release works with both Visual Studio 2008 and Visual Studio 2010. So what does it do? Well heres what Olaf has to say: This Visual Studio Integration Package is a proof of concept in: Aggregation of online content within the Visual Studio IDE. Analysis of development activities within the Visual Studio IDE. This combination of features allows Suggested Resources for .NET developers to pro-actively suggest online content that applies on the task being performed by a developer... A bit like having a programming pair that searches for online resources while you focus on getting the job done. For more info, screenshots and downloads, head to the Codeplex project site or the Visual Studio Gallery page.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.

• How to explain a layperson why a developer should not be interrupted while neck-deep in coding?

  - by András Szepesházi

  If you just consider the second part of my question, "Why a developer should not be interrupted while neck-deep in coding", that has been discussed a number of times by smart people. Heck, even the co-founder of SO, Joel Spolsky, wrote a blog post about "getting in the zone" and "being knocked out of the zone" and why it takes an average of 15 minutes to achieve productivity when participating in complex, software development related tasks. So I think the why has been established. What I'm interested in is how to explain all that to somebody who doesn't know beans about Beans (khmm I mean software development). How to tell the wife, or the funny guy from accounting at the workplace, or the long time friend who pings you on Skype every 30 minutes with a "Wazzzzzzup?!", that all the interruptions have a much deeper impact on your work than the obvious 30 seconds they took from your time. Obviously you can't explain it by sentences like "I have to juggle a lot of variable names in my short term memory" unless you want to be the target of blank stares or friendly abuse. I'd like to be able to explain all that to non-developers in a way that will make them clearly understand - without being offensive, elitist or too technical.

• How to implement physical effect, perspective effect on Android

  - by asedra_le

  I'm researching about 2D game for Android to implement an Android Game Project. My project looks nearly like PaperToss. Instance of throwing a page, my game will throw a coin. Suppose that I have a coin put in three-dimensional that have coordinates at A(x,y,z). I throw that point ahead, after 1/100 second, that coin move from A(x,y,z) to A'(x',y',z'). By this way, I have two problems need to solve. Determine the formulas can be used to compute the coordinates of the coin at time t. This problem is under-researching. I have no idea to solve this problem. Mapping three-dimensional points to a two-dimensional and use those new coordinates (a two-dimensional coordinates) to draw our coin on screen. I have found two solutions for this problem: Orthographic projection & Perspective projection However, my old friend said that OpenGL supports to solve problems like my problems. Any body have experiences about my problems? Help me please :) Thank for reading my question.

• SQL SERVER – A Puzzle Part 2 – Fun with SEQUENCE in SQL Server 2012 – Guess the Next Value

  - by pinaldave

  Before continuing this blog post – please read the first part of the SEQUENCE Puzzle here A Puzzle – Fun with SEQUENCE in SQL Server 2012 – Guess the Next Value. Where we played a simple guessing game about predicting next value. The answers the of puzzle is shared on the blog posts as a comment. Now here is the next puzzle based on yesterday’s puzzle. First execute the script which I have written here. The only difference between yesterday’s script is that I have removed the MINVALUE as 1 from the syntax. Now guess what will be the next value as requested in the query. USE TempDB GO -- Create sequence CREATE SEQUENCE dbo.SequenceID AS BIGINT START WITH 3 INCREMENT BY 1 MAXVALUE 5 CYCLE NO CACHE; GO -- Following will return 3 SELECT next value FOR dbo.SequenceID; -- Following will return 4 SELECT next value FOR dbo.SequenceID; -- Following will return 5 SELECT next value FOR dbo.SequenceID; -- Following will return which number SELECT next value FOR dbo.SequenceID; -- Clean up DROP SEQUENCE dbo.SequenceID; GO Above script gave me following resultset. 3 is the starting value and 5 is the maximum value. Once Sequence reaches to maximum value what happens? and WHY? I (kindly) suggest you try to attempt to answer this question without running this code in SQL Server 2012. I am very confident that irrespective of SQL Server version you are running you will have great learning. I will follow up of the answer in comments below. Recently my friend Vinod Kumar wrote excellent blog post on SQL Server 2012: Using SEQUENCE, you can head over there for learning sequence in details.

• Complimentary Refills

  - by onefloridacoder

  My son and I were out to dinner and right after we sat down, he combs the menu to locate the soda  selection.  Then he looks up at me and says “Looks like we get free refills here, sweet!”  While we were sitting there I was thinking where that statement came from and I remember one time where he was helping to figure out the tip and saw that were we charged for six sodas, but there were only four of us at the table.  I would say that’s when this started for eateries he’s not familiar with. I was talking a friend of mine this week and this thought came to me, why can’t we manage expectations like my son – find out before the order is placed.  Find out what’s expected first then use the other bits of guidance to move forward.  But how many times have we all paid way to much for something we thought was free on a project – me, plenty.  This quote is going up in my work space, next to one I picked up Corey Haines’ Software Craftsmanship talk at Open Agile Romania - “Work != Practice”.  So if anyone else has gotten burnt, maybe check the menu, it will be in the area where the customer will pick two from the list of “Price, Quality, or Speed”.  Refills will be listed just beneath that.

• Ubuntu's security, Gaming, X server, situation [closed]

  - by ShortCircuit

  Little background story. So when I first heard about the NSA spying on people I wasn't surprised, it also was the reason why I switched to Ubuntu. (Full time) It had it's disadvantages when comparing to Windows and it's AAA games and other stuff. My best friend is somewhat upset about me, using full time Ubuntu, because we play a game named "Dayz (an addon for Arma II)" and WineHQ wasn't of any help. Not to mention that he keeps asking me if WineHQ can run Dayz, but he clearly doesn't understand the situation of WineHQ, that it's free, that you have to be happy with what you got at the moment. (I'm not going to dual boot because, how else is gaming on Ubuntu/Linux going to happen?) But whenever I was in a nasty situation where I could do something so simply on Windows and not/hard on Ubuntu, I always thought "It's almost virus free, It's free, No one is spying on me." My Questions: My English isn't all that good, so could some one simplify/explain what the hell is going on the below standing link? Ubuntu Spyware: What to Do? https://www.gnu.org/philosophy/ubuntu-spyware.html When will gaming on Linux/Ubuntu be a real thing? I've heard that the X server's code is a mess and that Wayland will replace X server. When/will this come reality? (I might have understood this wrong.)

• Newly installed Ubuntu 12.10 and weird graphics

  - by Benji Marshall

  My machine: 2 GB RAM Intel Pentium Dual core E2180 @ 2 GHz NVIDIA GeForce 6200 LE My friend had recommended Ubuntu to me and I thought I might as well get used to Linux in anticipation for my Raspberry Pi. He said that Wubi was the easiest way to install and I installed it using Wubi. On my first ever boot up of Ubuntu from the Windows Bootloader started normally, and I logged on in a normal fashion, and my desktop loaded normally. I then pressed the Windows key/Power key and everything went wrong. Random lines of yellow and blue appeared on my screen, and changed location when I moved my mouse. The lines stayed for a few seconds and then partially went to I could sort of use my computer. I tried moving my mouse and the entire desktop looked like it broke apart, fragments of it just scatter across my screen at random angles. I could move my mouse and the pointer would move but clicking did nothing. I had to turn off my machine by removing the plug. I would love to get off Windows, but at least the doesn't completely mess up the graphics, and is relatively usable. Please help me solve this....

• Restful Java based web services in json + html5 and javascript no templates (jsp/jsf/freemarker) aka fat/thick client

  - by Ismail Marmoush

  I have this idea of building a website which service JSON data through restful services framework. And will not use any template engines like jsp/jsf/freemarker. Just pure html5 and Javascript libs. What do you think of the pros and cons of such design ? Just for elaboration and brain storming a friend of mine argued with the following concerns: sounds like gwt this way you won't have any control over you service api for example say you wanna charge the user per request how will you handle it? how will you control your design and themes? what about the 1st request the browser make? not easy with this all of the user's requests will come with "Accept" header "application/json" how will you separate browser from abuser? this way all of your public apis will be used by third party apps abusively and you won't be able to lock it since you won't be able to block the normal user browser We won't use compiled html anyway but may be something like freemarker and in that case you won't expose any of your json resources to the unauthorized user but you will expose all the html since any browser can access them all the well known 1st class services do this can you send me links to what you've read? keep in mind the DOM based XSS it will be a nightmare ofc, if what you say is applicable.

• Is there a way to legally create a game mod?

  - by Rodrigo Guedes

  Some questions about it: If I create a funny version of a copyrighted game and sell it (crediting the original developers) would it be considered a parody or would I need to pay royalties? If I create a game mod for my own personal use would it be legal? What if I gave it for free to a friend? Is there a general rule about it or it depends on the developer will? P.S.: I'm not talking about cloning games like this question. It's all about a game clearly based on another. Something like "GTA Gotham City" ;) EDIT: This picture that I found over the internet illustrate what I'm talking about: Just in case I was not clear: I never created a mod game. I was just wondering if it would be legally possible before trying to do it. I'm not apologizing piracy. I pay dearly for my games (you guys have no idea how expensive games are in Brazil due to taxes). Once more I say that the question is not about cloning. Cloning is copy something and try to make your version look like a brand new product. Mods are intended to make reference to one or more of its source. I'm not sure if it can be done legally (if I knew I wasn't asking) but I'm sure this question is not a duplicate. Even so, I trust in the moderators and if they close my question I will not be offended - at least I had an opportunity to explain myself and got 1 good answer (by the time I write this, maybe some more will be given later).

• iptables unresolved dependencies

  - by tertle

  I'm trying to setup OpenVPN Access Server on a VPS running ubuntu 9.10 for a friend so she can play games from her uni campus. The problem is I keep running into this error when trying to start openvpn. Service deferred error: IPTablesServiceBase: failed to run iptables-restore [status=1]: ['FATAL: Could not load /lib/modules/2.6.18-028stab070.14/modules.dep: No such file or directory', 'FATAL: Could not load /lib/modules/2.6.18-028stab070.14/modules.dep: No such file or directory', 'iptables-restore: line 46 failed']: internet/base:1175,internet/base:752,internet/process:45,internet/process:306,internet/_baseprocess:48,internet/process:775,internet/_baseprocess:60,svc/pp:116,svc/svcnotify:26,internet/defer:238,internet/defer:307,internet/defer:323,sagent/ipts:105,sagent/ipts:39,util/error:52,util/error:32 service failed to start due to unresolved dependencies: set(['user', 'iptables_openvpn']) service failed to start due to unresolved dependencies: set(['user', 'iptables_openvpn']) service failed to start due to unresolved dependencies: set(['iptables_openvpn']) Now I've already got my provider to enabled the TUN/TAP device driver and I checked this using # cat /dev/net/tun Which returned “File descriptor in bad state” Which I believe means it's enabled. After extensive searching, I've been unable to find any solution other than people suggesting to make sure TUN/TAP device driver is enabled. Any ideas on how to solve my issue? I'm not very experience with linux and I feel in over my head here so any advice is greatly appreciated. --edit-- Just stumbled across this Not sure how I missed it earlier. I believe I need to get modprobe ipt_mark & modprobe ipt_MARK run on the hostnode by my provider. Is this correct and something I should try get done.

• Input signal out of range; Change settings to 1600 x 900

  - by Clayton

  I recently installed Ubuntu 12.04 onto my HP Pavilion, in an attempt to make the desktop able to dual-boot Windows 7 and Ubuntu. I managed to get down to the last step, and finished the installation process. After it prompted me to remove what I used to install Ubuntu, I did so, removing my SanDisk 8GB flash drive, and allowed the system to reboot. Like usual, the desktop booted with the HP image, with the options at the bottom(Boot Menu, System Recovery, etc). However, when it should have started up with Ubuntu(like I'm certain it should have done), I received the following error: Input signal out of range Change settings to 1600 x 900 From the time I installed the operating system, back in late August, till now, I've been trying to figure out how I would go about fixing this issue. My mom is also starting to get frustrated with my not having resolved the issue, as its the only desktop that has a printer installed. Is there any possible way to resolve this? To summarize the problem: -Successful boot -Screen brings up error -Screen goes to standby -Nothing else possible until desktop is rebooted, which will initiate the above three steps A few notes: -I did not back up my computer before I installed Ubuntu. I didn't have anything to write to, and basically just forgot to. : -I don't have a Recovery Disk. -I don't have the Windows 7 disk that is supposed to come with the computer. -It has been narrowed down by a friend on Skype that the problem lies with the display, and that the vga= boot command does have something to do with fixing the problem Thank you in advance for resolving this problem. I greatly appreciate it. ^^

• Reasonable technological solutions to create CRM using .NET eventually Java

  - by user1825608

  My background(If it's too long, just skip it please ; ) ): I am Java programmer(because of demand): mostly teacher for other students, worked on few thesis for others, but during my journey I discovered that .NET and Microsoft's tools are on at least two levels higher than Java and its tools so I want to learn more about them. I programmed little bit on Windows Phone(NFC Tags, TCP Clients, guitar tuner using internal microphone, simple RSS), used WPF, integrated WPF with Windows Forms, Apple Bonjour(.NET), I have expierience with IP cameras and with unusal problems, I learn Android, but I don't like it at all. Problem: I was asked by my friend to create CRM for small new company. There will maximum 20 workers in the company working at computers in few cities in the country(Poland). They just want to store contracts with the clients and client's data. I am not sure what exacly they do but probably sell apartments so there will be at most few thousands of contracts to store in far future. Now I am totally new to CRM but I want to learn. I have few questions: Should the data be stored on a server in the company's building running 24/7 or cloud. If cloud which one? Should I use ASPX or WPF. I read one topic about it but as far as I know aspx sites can be viewed from every device with internet browser: tablets, phones(Android, WP, iOS) and computers at the same time- so the job is done once and for all(Am I right?), I don't know nothing about aspx. Can WPF be also used in manner that does not need to port it for other platforms?
