• Location of development solutions on disk - Common or upto the individual

  - by dreza

  In our team meeting today a senior member brought up the proposal that we should be having a common location/structure for our development solutions. A couple of his points were: Making it common meant when talking about projects and emailing stuff everyone is on the same wavelength and knows where to look. If there is ever the need to hard code a location path then it will work across all developers pc's. He had a more few points to back up his suggestion but I unfortunately got distracted during the discussion and so didn't hear all of them. I have no issue with the idea and can see it's merits but I was wondering if it is common or even recommended that all developers place their code in the same folder structure. Or do developers like to have the flexibility of location solutions where-ever they want? We currently use SVN for our version control. In this case his recommendation was to place all code in: c:\Work\Development\<Customer>\<project>\Code\<solution>\ the code I guess actual path is irrelevant for this question but added for completeness.

  From XaaS to Java EE – Which damn cloud is right for me in 2012? | Markus Eisele Oracle ACE Director Markus Eisele wrestles with a timely technical issue and shares his observations on several of the alternatives. WebLogic Servier Domain Browser App (Android) My colleague Jeff Davies, a frequent speaker at OTN Architect Day events and a genuinely nice guy, emailed me last night with this message: "I just came across this app on Google Play. It allows WebLogic administrators to browse WLS 12c domain information. I installed it on my phone and tried it out. Works very fast." I'm an iPhone guy, but I'm perfectly comfortable taking Jeff at his word.The app is called WLS Domain Browser. Follow the link for more info from the Google Play site.

• Cannot enable Additional drivers for Broadcom in 12.10

  - by Compt

  tl;dr version: Additional Drivers does not work for enabling a driver in Ubuntu 12.10, however it worked in 12.04. I upgraded to Ubuntu 12.10 from 12.04 via a live USB. I did a fresh install to avoid any conflicts. From 12.04 I know that my wireless card has proprietary drivers that could be installed via Additional Drivers. I did eventually find additional drivers in the software sources menu, however when I attempt to switch to Broadcom 802.11 Linux STA wireless driver source from bcmwl-kernel-source, it not only does not work, it in fact disables my wireless completely. The only way to revert this is to restart, and revert back to "do not use the device". Then upon another restart, my wireless will function once again. I was curious if anyone else had this issue, and if there was a fix for it as of yet. I looked on launchpad and it may be a potential bug, but I am unsure. Any help would be greatly appreciated (and sorry for that wall of text). Until then, I'll continue to use my wireless as it is (or revert to 12.04), but I do notice a slower connection without it enabled.

• IE won't load directly-linked PNGs

  - by Johannes Rössel

  I remember having this issue in the past with previous versions as well but recently it started here again. Whenever I click a link that links directly to a PNG image I get a download dialog; the browser won't display it on its own. Inline PNGs are fine, though. Any ideas what causes this? It did work in the past. Preemptive warning: I'm not looking for advice to change my browser; I'm looking for a solution to a specific problem with one piece of software. Just ignore the fact that it may have religious importance.

  I'm trying to use the following script: $password = ConvertTo-SecureString "xxxx" -AsPlainText -Force $cred = New-Object System.Management.Automation.PSCredential("domain\Administrator", $password) $session = New-PSSession 192.168.xxx.xxx -Credential $cred Invoke-Command -Session $session -ScriptBlock { New-Cluster -Name "ClusterTest" -Node HOSTNAME } To remotely create a cluster (it's for testing purposes) on a Windows Server 2012 VM. I'm getting the following error: An error occurred while performing the operation. An error occurred while creating the cluster 'ClusterTest'. An error occurred creating cluster 'ClusterTest'. No credentials are available in the security package + CategoryInfo : NotSpecified: (:) [New-Cluster], ClusterCmdletException + FullyQualifiedErrorId : New-Cluster,Microsoft.FailoverClusters.PowerShell.NewClusterCommand All of my other remote commands (installing/making changes to DNS, DHCP, NPAS, GP, etc) work without an issue. Why is this one any different? The only difference is in the -ScriptBlock tag. Help!

• Best peer-to-peer game architecture

  - by Dejw

  Consider a setup where game clients: have quite small computing resources (mobile devices, smartphones) are all connected to a common router (LAN, hotspot etc) The users want to play a multiplayer game, without an external server. One solution is to host an authoritative server on one phone, which in this case would be also a client. Considering point 1 this solution is not acceptable, since the phone's computing resources are not sufficient. So, I want to design a peer-to-peer architecture that will distribute the game's simulation load among the clients. Because of point 2 the system needn't be complex with regards to optimization; the latency will be very low. Each client can be an authoritative source of data about himself and his immediate environment (for example bullets.) What would be the best approach to designing such an architecture? Are there any known examples of such a LAN-level peer-to-peer protocol? Notes: Some of the problems are addressed here, but the concepts listed there are too high-level for me. Security I know that not having one authoritative server is a security issue, but it is not relevant in this case as I'm willing to trust the clients. Edit: I forgot to mention: it will be a rather fast-paced game (a shooter). Also, I have already read about networking architectures at Gaffer on Games.

• Video lags/freezes in SMPlayer and VLC

  - by RanRag

  When I try to play my video files in SMPlayer it works fine but as soon as I switch to fullscreen mode(16:9) following thing happens: 1) Video starts lagging. 2) Audio and video goes out of sync. 3) CPU usage rises to ~50%. 4) SMPlayer starts to hang. My current SMPlayer configuration: 1)Video Output Driver = x11(slow) 2)Audio Output Driver = alsa(0.0-HDA Intel) 3)Cache = 8192 KB 4)Threads for decoding(MPEG-1/2 and H.264 only = 2 Things I tried solve this problem: 1) Tried changing video o/p driver to xv,gl. 2) Tried changing audio o/p driver to pulse. 3) Tried increasing cache size and also tried using nocache. Everything works fine on windows but I don't want to switch to windows just to play video files.

• Restrict Overriding memory_limit in php.ini

  - by Rohit Batra

  We have a issue that just came to our notice, some of our developers used ini_set('memory_limit', -1) to over-ride the php.ini memory_limit settings in their code files. Due to which sometimes our Memory/CPU usage is way far more than usual and we even have experienced server hanging/crashing many times. Is there any way to restrict these changes for certain params like memory_limit, upload_max_filesize & post_max_size? Users should not be able to edit them after a certain limit set? Sorry if i asked a dumb question, tried searching but there was no reference to this only found answers asking for increasing these parameters.

• Designing business objects, and gui actions

  - by fozz

  Developing a product ordering system using Java SE 6. The previous implementations used combo boxes, text fields, and check boxes. Preforming validation on action events from the GUI. The validation includes limiting existing combo boxes items, or even availability. The issue in the old system was that the action was received and all rules were applied to the entire business object. This resulted in a huge event change as options were changed multiple times. To be honest I have no idea how an infinite loop wasn't produced. Through the next iteration I stepped in and attempted to limit the chaos by controlling the order in which the selections could be made. Making configuration of BO's a top down approach. I implemented custom box models, action events, beans/binding, and an MVC pattern. However I still am unable to fully isolate action even chains. I'm thinking that I've approached the whole concept backwards in an attempt to stay closest to what was already in place. So the question becomes what do I design instead? I'm currently considering an implementation of Interfaces, Beans, Property Change Listeners to manage the back and forth. Other thoughts were validation exceptions, dynamic proxies.... I'm sure there are a ton of different ways. To say that one way is right is crazy, and I'm sure it will take a blending of multiple patterns. My knowledge of swing/awt validation is limited, previously I did backend logic only. Other considerations are were some sort of binding(jgoodies or otherwise) to directly bind GUI state to BO's.

• Webserver insists on opening "blog1.php" instead of "index.php"

  - by pepoluan

  I'm at my wits' end. I have just ripped out a website and in the process of rebuilding everything. Previously, the 'home page' of the website is a blog, with the address "www.mydomain.com/blog1.php". After exporting everything, I deleted the whole directory, and -- based on request -- immediately create a blog/ directory. The idea is to get the blog back up as soon as possible, and temporarily redirect people accessing www.mydomain.com to the blog. Accessing the blog via http://www.mydomain.com/blog/ works. So I put in an index.php file containing a (temporary) redirect to the blog's address. The problem: The server insists on opening blog1.php instead of index.php. Even after we deleted all the files (including .htaccess). And even putting in a new .htaccess file with the single line of DirectoryIndex index.php doesn't work. The server stubbornly wants blog1.php. Now, the server is actually a webhosting, so I have no actual access to it. I have to do my work via cPanel. Currently, I work around this issue by creating blog1.php; but I really want to know why the server does not revert to opening index.php. Did I perhaps miss some important settings in the byzantine cPanel menu page?

• where to start and lack of motivation

  - by anoguy

  I have a few questions that have been bothering me for quite a while, maybe you guys can give me some tips. So let me give a very brief explanation about what I am doing at the moment (like someone cares lol). At the moment I am a last year student on computer science. And like most of you already know is that you won't learn deep programming there, you need to learn it yourself. So at the moment I know like the basics of c++, java, html, php. But it's all bits of this and bits of that. I seriously want to dive deeper in the programming world but there are so many programming languages on the web and there is so much information that i don't know where to start any more.. And that's not the biggest issue, I also lost a bit of my motivation for programming and I like to get more motivation for it so that I love what I do (I am also a very lazy person btw, that's also a problem playing here). So can you guys give me some tips for helping me, because I really want to get pumped up and make cool stuff. (sry for my bad english XD)

• How can Facebook's session get mixed up because of NAT and/or Proxy

  - by Alex

  Have received some reports from a customer (a very large company) they reported issues from clients who are using Facebook. These clients claim that once in a while when they log in to Facebook they end up in someone else's session. I know that network is NATed then Proxied before getting to Facebook.com. Although I'm not able to explain how this issue can occur. Is it possible that the Proxy is not sending the right session back to the clients? How can they end up with someone else's session since Facebook is cookie based session?? Anyone seen this before?

• apache returning "The connection was reset"

  - by usjes

  One of my dedicated servers had some network issue today and the data center has to replace some router. Since then the sites on that server returns "The connection was reset" error most of the time. I tried installing nginx and it opens better, but it still shows the error sometimes. Everything in the config seems normal, what could be causing this error? UPDATE: Just noticed that in whm apache status there are always only 1 requests currently being processed, 8 idle workers. I know for sure the server received thousands of requests per minute. What could be limiting this to such a low number?

• getting a 404/403 error for payment gateway

  - by Obay Ouano

  We are setting up an online payment facility using a payment gateway. After the payment gateway finishes processing the credit card details for a payment, the user is redirected to a "403 Forbidden" page. The logs show: [MY_IP_ADDRESS_HERE] - - [SOME_DATE_HERE] "GET /POSTBACK_URL.php?txnid=1338434567&result=failure&reason=The+remote+server+returned+an+error%3a+(404)+Not+Found.&digest=7a115270c56df5945c43ad86e56b2e930a3cfd50 HTTP/1.1" 404 - "PAYMENT_GATEWAY_URL_HERE" "BROWSER_DETAILS_HERE" It means that when the PAYMENT_GATEWAY_URL attempts to open our POSTBACK_URL, it gets a 404 error, is that correct? But why does the page say "403 Forbidden"? Anyway, we tried to copy-paste that same URL into the browser window, and the page is opened successfully, with our programmed error notification message. So, why couldn't it be opened when the payment gateway tried to redirect to it, but we could? Is this some sort of permissions issue? If so, the postback URL's file permissions are already 755. What am I missing?

• Dual monitors with one above the other?

  - by Felix

  I'm using Gnome 3 and proprietary Nvidia drivers. I have tried to set in nvidia-settings my external monitor to be "above" my main one (it's a laptop). However, when I try to drag a window up from the main display to the external one, it gets stuck and can't move past a certain point. Trying to maximize it changes its decoration so it looks maximized (i.e. no borders, etc), but its size or position doesn't change. Now, if I set my external monitor to be "to the left" of the main one, it works, which is why I'm suspecting this is a Gnome issue, not an Nvidia one. Anyone know how to fix this? Update: some versions: Gnome: 3.2.2.1 Nvidia: 280.13 Update 2: I can see that Gnome 3.4 is out, and among the release notes is better external monitor support. However, they only mention a small fix that is unrelated to my problem. Can anyone with Gnome 3.4 and access to an external monitor please test this out and tell me if it works? I don't want to go through the hassle of upgrading my Ubuntu installation unless I know for certain it's going to fix the problem.

• Thoughts on type aliases/synonyms?

  - by Rei Miyasaka

  I'm going to try my best to frame this question in a way that doesn't result in a language war or list, because I think there could be a good, technical answer to this question. Different languages support type aliases to varying degrees. C# allows type aliases to be declared at the beginning of each code file, and they're valid only throughout that file. Languages like ML/Haskell use type aliases probably as much as they use type definitions. C/C++ are sort of a Wild West, with typedef and #define often being used seemingly interchangeably to alias types. The upsides of type aliasing don't invoke too much dispute: It makes it convenient to define composite types that are described naturally by the language, e.g. type Coordinate = float * float or type String = [Char]. Long names can be shortened: using DSBA = System.Diagnostics.DebuggerStepBoundaryAttribute. In languages like ML or Haskell, where function parameters often don't have names, type aliases provide a semblance of self-documentation. The downside is a bit more iffy: aliases can proliferate, making it difficult to read and understand code or to learn a platform. The Win32 API is a good example, with its DWORD = int and its HINSTANCE = HANDLE = void* and its LPHANDLE = HANDLE FAR* and such. In all of these cases it hardly makes any sense to distinguish between a HANDLE and a void pointer or a DWORD and an integer etc.. Setting aside the philosophical debate of whether a king should give complete freedom to their subjects and let them be responsible for themselves or whether they should have all of their questionable actions intervened, could there be a happy medium that would allow the benefits of type aliasing while mitigating the risk of its abuse? As an example, the issue of long names can be solved by good autocomplete features. Visual Studio 2010 for instance will alllow you to type DSBA in order to refer Intellisense to System.Diagnostics.DebuggerStepBoundaryAttribute. Could there be other features that would provide the other benefits of type aliasing more safely?

• Use C2WTS to get a classic windows identity from a claims identity

  - by Sahil Malik

  SharePoint, WCF and Azure Trainings: more information I know you’re going to find this useful at some point. A lot of backend systems still demand classic windows identities, but everything we do now has moved to claims. So sometimes (albeit rare), we have to translate a claims identity into a classic windows identity. This is where the “Claims to Windows Token Service” comes into play. SharePoint 2010 and 2013 make use of this but you can use this in any .NET application. First of all, there are some basic requirements for this to work, First, you will need the string value of a UPN claim. Just a string value, really! This means you can also use FBA or anything else. The “proper” way to do this of course is that you must originate this from a AD backed claim. So a user authenticated using ADFS or similar would be perfect. Just remember that you must issue the UPN claim. Read full article ....

• How do client-server cooperation based games like Diablo 3 work?

  - by edgar

  Diablo 3 cooperates with Blizzard servers even during single player games. In fact, Blizzard has had problems with the games "melting their servers." I would like to ask: How do the client and the server communicate? What details does the client leave to the server, and vice versa? What details are redundant - both the client and the server know - and how often do they disagree? The previous paragraph contains the important questions, but I have a few more that I must explain my motivation towards. I am interested in the programming of botting. Ethical botting - I don't plan on actually abusing the automation to run 24/7. I just find it to be a great programming challenge to glean information from a game, and then make decisions from that information. I am stuck in the starting gate. The unofficial questions from this post would be: How can I make a bot (language, tools, libraries)? Can I get information through the communication between client and server, rather than the brute force pixel detection easily used in more static games? There probably is a trust issue, and to that all I can say is that I promise not to abuse the answers. But please feel free to answer any of the questions you feel comfortable with. Thank you!

• Four Easy Ways to Save a Rocky CRM Relationship

  - by Divya Malik

   Today, I am pleased to introduce our guest blogger Luke Christianson. Luke is  an Application Sales rep based out of Minneapolis, MN.  You can find him on LinkedIn and follow him on Twitter. In any relationship, sooner or later, the excitement fades away.  The honeymoon period gives way to the old routines you had, before you committed to each other and you eventually begin doing things apart from one another.  I’m not talking about a marriage…  Well, I guess I am.Commitment to a CRM tool and building a deep and lasting relationship is not much different than the basics of a traditional love story.  After your controlled CRM pilot program, and maybe the National Sales Meeting where you couldn’t escape those three wonderful letters, CRM, you will soon find that if you haven’t designed an environment where it’s going to enable your reps to make more money, the relationship is doomed.   . If you’re currently in a dysfunctional CRM relationship, here are 4 simple tips to re-engaging users and getting that spark back. Shadow a Sales Rep:   Chances are you can find out exactly what is preventing your sales reps from using the application by simply watching how they go about their day.  Sales reps are driven by money, not by additional administrative duties.  Your system needs to be setup so that they can get the information they need quickly, facilitate making key updates and run their business out of one easy-to-use application.  Increase your sales team’s productivity by 5% automatically:    Cancel the weekly forecast calls with your reps and require them update their opportunities in CRM.  Something else that I’ve seen work extremely well, is when you do Monthly or Quarterly reviews, do not let your sales reps bring anything into the room with them; no spreadsheets, notebooks, or computers.  Everything they need to tell you should be able to be put into CRM and fully accessible by the Sales Manager at any time.  Tool time:      Make sure the tools that you have selected meet both your short-term goals and your long term goals.   You need tools that can adapt like your business does.  You probably can’t wait two months for an update to a picklist value or for the addition of a simple workflow rule.  Do you feel the tools that are in place can create the experience you want for your users? and finally, if all else fails... Keep It Simple, Stupid:     Do you really need to require 15 fields to create an Opportunity?  Do you need to clutter the interface with different reports that don’t add daily value?  Most CRM systems on the market today are flexible enough today that your admin could clean up most of the unnecessary interface ‘noise’ in a few hours.  If they're not, see #3. Every strong relationship can be tedious at times, you’ll fight and eventually make amends, you may even threaten to upgrade to a newer model…  But be patient and think about what you want to achieve and you’ll find a partner for life.

• DoubleCommand Non-Functional on 10.6.3.

  - by Tim Visher

  I have a 1st or 2nd generation MacBook running 10.6.3. I want to remap my enter key to Ctrl and my right option key to enter (Emacs… yeah) and DoubleCommand seems to be precisely what the doctor ordered. Unfortunately, after having installed the latest version, it seems to be doing absolutely nothing. The correct settings are saved and active, but none of the remapping is taking effect. Are there any known issues with other OS X plug-ins (I run pretty heavily modified) or extensions that I should be aware of? What could the issue be? I initially tried to set only the User settings and then logged out and logged back in but nothing happened. I then tried saving them to System as well and logged out and in and nothing. Then I restarted the machine… twice… and nothing happened. Thanks in advance!

• Why is the network speed on my Mac Pro (early 2009) so slow?

  - by Rafael

  I have a really weird networking issue on my Mac Pro (Early 2009). I can’t get higher network speeds than about 2MBit/s. It doesn’t matter if this is over AirPort or one of the Ethernet ports. An iMac and a Mac mini in the same network with almost the same configuration get about 25-30 MBit/s. I’ve read a couple of things about this on the official Apple forums, but there is no helpful information. Anyone else with Mac Pro network speed issues and who knows how to solve them?

• XAMPP localhost and 127.0.0.1 don't work but computer name does work

  - by Steven

  I am running on a vista. Localhost and 127.0.0.1 do not work anymore but my computer name still works. Localhost and 127.0.0.1 only show a blank page however using my computer name can access xampp homepage as well as my server files. I am assuming there is something wrong with my hosts file but when i checked it looks fine: 127.0.0.1 localhost is the only thing in there that is not commented out, which seems right according to what I've seen on the web so far. I had a trojan recently that I got rid of so I believe that definitely has something to do with it. It was msa.exe among potentially others but I think I got rid of it with Malwarebytes. This is the only issue that is left. Thanks!
