• Guidance: How to layout you files for an Ideal Solution

  - by Martin Hinshelwood

  Creating a solution and having it maintainable over time is an art and not a science. I like being pedantic and having a place for everything, no matter how small. For setting up the Areas to run Multiple projects under one solution see my post on  When should I use Areas in TFS instead of Team Projects and for an explanation of branching see Guidance: A Branching strategy for Scrum Teams. Update 17th May 2010 – We are currently trialling running a single Sprint branch to improve our history. Whenever I setup a new Team Project I implement the basic version control structure. I put “readme.txt” files in the folder structure explaining the different levels, and a solution file called “[Client].[Product].sln” located at “$/[Client]/[Product]/DEV/Main” within version control. Developers should add any projects you need to create to that solution in the format “[Client].[Product].[ProductArea].[Assembly]” and they will automatically be picked up and built automatically when you setup Automated Builds using Team Foundation Build. All test projects need to be done using MSTest to get proper IDE and Team Foundation Build integration out-of-the-box and be named for the assembly that it is testing with a naming convention of “[Client].[Product].[ProductArea].[Assembly].Tests” Here is a description of the folder layout; this content should be replicated in readme files under version control in the relevant locations so that even developers new to the project can see how to do it. Figure: The Team Project level - at this level there should be a folder for each the products that you are building if you are using Areas correctly in TFS 2010. You should try very hard to avoided spaces as these things always end up in a URL eventually e.g. "Code Auditor" should be "CodeAuditor". Figure: Product Level - At this level there should be only 3 folders (DEV, RELESE and SAFE) all of which should be in capitals. These folders represent the three stages of your application production line. Each of them may contain multiple branches but this format leaves all of your branches at the same level. Figure: The DEV folder is where all of the Development branches reside. The DEV folder will contain the "Main" branch and all feature branches is they are being used. The DEV designation specifies that all code in every branch under this folder has not been released or made ready for release. And feature branches MUST merge (Forward Integrate) from Main and stabilise prior to merging (Reverse Integration) back down into Main and being decommissioned. Figure: In the Feature branching scenario only merges are allowed onto Main, no development can be done there. Once we have a mature product it is important that new features being developed in parallel are kept separate. This would most likely be used if we had more than one Scrum team working on a single product. Figure: when we are ready to do a release of our software we will create a release branch that is then stabilised prior to deployment. This protects the serviceability of of our released code allowing developers to fix bugs and re-release an existing version. Figure: All bugs found on a release are fixed on the release.  All bugs found in a release are fixed on the release and a new deployment is created. After the deployment is created the bug fixes are then merged (Reverse Integration) into the Main branch. We do this so that we separate out our development from our production ready code.  Figure: SAFE or RTM is a read only record of what you actually released. Labels are not immutable so are useless in this circumstance.  When we have completed stabilisation of the release branch and we are ready to deploy to production we create a read-only copy of the code for reference. In some cases this could be a regulatory concern, but in most cases it protects the company building the product from legal entanglements based on what you did or did not release. Figure: This allows us to reference any particular version of our application that was ever shipped.   In addition I am an advocate of having a single solution with all the Project folders directly under the “Trunk”/”Main” folder and using the full name for the project folders.. Figure: The ideal solution If you must have multiple solutions, because you need to use more than one version of Visual Studio, name the solutions “[Client].[Product][VSVersion].sln” and have it reside in the same folder as the other solution. This makes it easier for Automated build and improves the discoverability of your code and its dependencies. Send me your feedback!   Technorati Tags: VS ALM,VSTS Developing,VS 2010,VS 2008,TFS 2010,TFS 2008,TFBS

• Swap, Swapiness and Standby: swapping starts when waking up

  - by mdo

  I'm running running Ubuntu 12.04 on a Lenovo W500 (Core2Duo T9400, 4GB Ram) Current kernel: 3.2.0-32-generic #51-Ubuntu SMP Wed Sep 26 21:33:09 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux -- but the problems exists since a couple of months, surviving quite a few software (includig kernel) updates I regularly put my machine into suspend-to-ram (S3) and when the machine comes back up Ubuntu starts to swap out processes. I was able to observe that the used swap-space starts to grow right after the box returns. See munin graphs below, the gap (obviously) shows the timeframe in STR. Needless to say that the box becomes unusable while swapping, load goes up beyond 10. What I've done so far: lowered swappiness from default (60) to 10 (via /etc/sysctl.conf: vm.swappiness=10) -- this has improved the situation much, but sometimes the problem comes back, I have not found a trigger (like memory usage) for this for now lowered swappiness to 5 -- perhaps this has brought an improvement again Before going to STR the box ran stable without (swapping) problems for hours. Today when the issue showed up again I used this script (- http://stackoverflow.com/questions/479953/how-to-find-out-which-processes-are-swapping-in-linux) to find what processes have the most used swap space. The result after the swap orgy is like that (all PIDs with more than 10M usage): Overall swap used: 2121344 kB ======================================== kB pid name ======================================== 439520 17491 java 208148 22719 firefox 136640 4337 /usr/bin/quodli 120852 5271 chrome 81832 5264 chrome 74284 17003 chrome 65368 16960 chrome 57088 3675 chrome 56184 30923 chrome 54412 11331 chrome 54264 3878 chrome 51508 18382 chrome 50088 3163 zeitgeist-fts 49772 15543 chrome 41344 15355 compiz 35040 1161 mysqld 32124 18374 chrome 30940 11339 chrome 30044 5752 chrome 28780 4235 plugin-containe 24576 31246 empathy-chat 23840 17703 chrome 22512 3207 ubuntuone-syncd 21588 1937 ntop 18336 2021 asterisk 17200 3915 chrome 13964 1935 Xorg 12036 10679 chrome 11104 30782 empathy 11056 2889 python 10932 16565 knotify4 The java instance at the top is IntelliJ. IntelliJ, Firefox and Chrome also were all used right before the box was put to STR. So my question is: can I somehow prevent these swapouts AND why do they happen? Is it perhaps related to some misidentification of idle processes? I'm not looking for resolutions like: turn off swap buy more RAM Thanks in advance!

• How do I export banshee library settings to another machine?

  - by nityabaddha

  I am trying to downgrade my distro. The thing is, I have spent some few hours organising my music library and I do not want to lose my database. I have checked 'write meta data to files'. And so, my understanding is, that if I just import those same mp3s into a new library, those files will be arranged in the same order in the library. But this doesn't sound like a safe enough option. I'm moving from 11.10 to 10.04. Any help would be greatly appreciated. newbie

• Unable to install mysql in ubuntu

  - by Anand

  I purged my existing mysql-server from ubuntu and re-installed the same. This was due there was an upgrade from my ubuntu and I was unable to start my sql-server. After cleaned up and taking backup of my data , I re-insalled mysql. During installaion I received following message popup.

• How to price code reviews to encourage good behavior?

  - by Chris Clark

  I work for a company that has a hosted .net internet application with many clients. Those clients often want to write customizations for our application. We have APIs to hook into the app, but the customizations themselves are written in .net. This is a shared, secure hosting environment and we have to code review these customizations before we can deploy them in our datacenter to ensure that they don't degrade performance, crash our servers, or open any security vulnerabilities. We charge for these code reviews. The current pricing model is simply a function of the number of lines of code. I think this is a bad idea for a variety of reasons, but primarily because, if we are interested in verifying that the code works as expected, we should be incentivizing good, readable code, not compaction. I would like to propose a pricing model that incorporates some, or all of the following as inputs: Lines of code Cyclomatic complexity Avg function length # of functions Are there any other metrics I should incorporate, or other ideas for how we can reasonably create pricing for code reviews that encourages safe and understandable code?

• Are there any risk if your DNS's SOA or admin contact are using the same domain as the DNS

  - by Yoga

  For example, Google.com [1] The SOA email is : dns-admin.google.com The contact is: Administrative Contact: DNS Admin Google Inc. dns-admin.google.com As you can see, both are using google.com, I am thinking it is safe to use the same domain, i.e. consider the case you lost control of the domain, you can receive email also. (Of course Google is a public company so the chance is low, but might occur for smaller company that their domain might be stolen..) So, do you recommend use your the same domain as the contact or others free services such as gmail? [1] http://whois.domaintools.com/google.com

• Nginx and Google Appengine Reverse Proxy Security

  - by jmq

  The scenario is that I have a Google compute node running Nginx as a reverse proxy to the google appengine. The appengine is used to service REST calls from an single page application (SPA). HTTPS is used to the Nginx front end from the Internet. Do I also need to make the traffic from the Nginx reverse proxy to the appengine secure by turning on HTTPS on the appengine? I would like to avoid the overhead of HTTPS between the proxy and the backend. My thinking was that once the traffic has arrived at Nginx encrypted, decrypted in Nginx, and then sent via the reverse proxy inside of Google's infrastructure it would be secure. Is it safe in this case to not use HTTPS?

• Is there an open source license for this?

  - by Philip

  I have written code at home, on my own time and using my own knowledge and equipment, while under no contract or NDA. I want to make this code open source so that I can use it in software I write for an employer, without denying myself the right to use it at home or elsewhere later. I'm not sure if saying it is in the "public domain" would fit this purpose, or if I need to find an open source license. I want anyone to be able to use the code in closed source proprietary software with zero requirements for including a license with the source or binary. And I want to minimize the risk of anyone being sued for using it. (I'm aware that one can never be 100% safe from being sued.) Is there an open source license that fits this purpose? To what extent is what I want to do even possible? I wouldn't mind putting the license in comments in the code files themselves, but that obviously doesn't go with the binary.

• Story of success: MySQL Enterprise Backup (MEB) was successfully integrated with IBM Tivoli Storage Manager (TSM) via System Backup to Tape (SBT) interface.

  - by user13334359

  Since version 3.6 MEB supports backups to tape through the SBT interface.The officially supported tool for such backups to tape is Oracle Secure Backup (OSB).But there are a lot of other Storage Managers. MEB allows to use them through the SBT interface. Since version 3.7 it also has option --sbt-environment which allows to pass environment variables, not needed by OSB, to third-party managers. At the same time MEB can not guarantee it would work with all of them.This month we were contacted by a customer who wanted to use IBM Tivoli Storage Manager (TSM) with MEB. We could only say them same thing I wrote in previous paragraph: this solution is supposed to work, but you have to be pioneers of this technology. And they agreed. They agreed to be the pioneers and so the story begins.MEB requires following options to be specified by those who want to connect it to SBT interface:--sbt-database-name: a name which should be handed over to SBT interface. This can be any name. Default, MySQL, works for most cases, so user is not required to specify this option.--sbt-lib-path: path to SBT library. For TSM this library comes with "Data Protection for Oracle", which, in its turn, interfaces with Oracle Recovery Manager (RMAN), which uses SBT interface. So you need to install it even if you don't use Oracle.--sbt-environment: environment for third-party manager. This option is not needed when you use OSB, but almost always necessary for third-party SBT managers. TSM requires variable TDPO_OPTFILE to be set and point to the TSM configuration file.--backup-image=sbt:: path to the image. Prefix "sbt:" indicates that image should be sent through SBT interfaceSo full command in our case would look like: ./mysqlbackup --port=3307 --protocol=tcp --user=backup_user --password=foobar \ --backup-image=sbt:my-first-backup --sbt-lib-path=/usr/lib/libobk.so \ --sbt-environment="TDPO_OPTFILE=/path/to/my/tdpo.opt" --backup-dir=/path/to/my/dir backup-to-imageAnd this command results in the following output log: MySQL Enterprise Backup version 3.7.1 [2012/02/16] Copyright (c) 2003, 2012, Oracle and/or its affiliates.

• Is there a language between C and C++?

  - by Robert Martin

  I really like the simple and transparent nature of C: when I write C code I feel unencumbered by "leaky abstractions" and can almost always make a shrewd guess as to the assembly I'm producing. I also like the simple, familiar syntax for C. However, C doesn't have these simple, helpful doodads that C++ offers like classes, simplified non-cstring handling, etc. I know that it's all possible to implement in C using jump tables and the like, but that's a bit wordy at times, and not very type-safe for various reasons. I'm not a fan of the over-emphasis on objects in C++, though, and I'm gun shy of the 'new' operator and the like. C++ seems to have just a few too many hiccups to, for instance, be used as a system programming language. Does there exist a language that sits between C and C++ on the scale of widgets and doodads? Disclaimer: I mean this as purely a factual question. I do not intend to anger you because I don't share your view that C{,++} is good enough to do whatever I'm planning.

• Lack of ideas for startup equals slack career?

  - by Fanatic23

  After 12-15 years of working in the same industry, if a person does not have any new ideas for a startup then is it safe to say that his/her career has not reached its potential? We are not talking of implementation strategies or insights here to fructify the startup -- just great ideas which can change things for the better. Not your source code optimization. I mean a radical way of looking at things. If you lot disagree with this line of thinking, then please share some examples where despite such a long span a person can end up without new ideas.

• Database modularity with EBS volumes

  - by Eclyps19

  I would like to add modularity to my websites on EC2 instances by encapsulating the site files and the mysql files in their own EBS volumes. The end result that I'm going for is the ability to quickly mount a volume or two to different servers running the same AMI (for testing/development/emergency maintenance, etc), as well as maintain separate snapshots of each. I'm able to do this fairly easily with a single database by symlinking my mounted database EBS to the appropriate places (/var/lib/mysql, /etc/my.cnf, /var/log/mysqld.log), but I'm not sure if it would even be possible be possible to have multiple databases on different EBS volumes running concurrently. Example: /website1/www.website.com /database1/ /website2/www.otherwebsite.com /database2/ Could anybody shed some light on this for me? Is it possible? Is it a bad idea? Thanks.

• Why are my 3ds Max .fbx exports huge?

  - by abracadabra1980

  I've made an animation in 3ds Max and want to export it to .fbx and import it into Unity. I've done this once without problems. But this time, my .max file is 2,8MB and my .fbx file came out a huge 630MB! There's nothing wrong with my model: I exported it from a Blender model (to .fbx) and imported it to 3ds max (converted it to an editable poly) to do my rigging and animation. As soon as I import some .bip animations, I get these huge files. Is there a safe way to get smaller file sizes? I don't mind redoing the rigging if I can solve this.

• What happens if you're unable to solve a problem?

  - by gablin

  I'm a year away from graduating from university, and I'm really looking forward to solving practical problems. Especially non-trivial ones which require a bit of research and a lot of thinking. But at the same time, that is also my greatest fear - being faced with a problem that I'm unable to solve, no matter how hard I try. And with pressure to deliver code on impending deadlines just around the corner, it does look a bit scary when viewing it from the safe playgrounds on uni (where the worst thing that can happen is that you have to redo a course or exam). So for those who have been in industry for any longer length of time, what would happen if you were told to solve a problem that you couldn't? Has it happened, and if so, what did happen? Did they just drop it and said "Oh well, guess we can make do with something else"? Were there consequences? Were you reprimanded, or even fired?

• Grub boot problems with older ubuntu

  - by denk doink

  This is my 1st post here and there are 2 problems that are inter-related. I'm not much of a Linux system person... the computer is a dedicated linux box without any windoze. 1) running 9.10 and had a boot failure last week. looks like a file was deleted or corrupted. i was unable to get it to work. realizing it was a boot issue, i took the CD and installed 9.04 to co-exist with 9.10 on the disc. 9.04 was put into a 2.5 gb ext3 partition. i was able to boot into 9.10 from grub menu selection. 9.04 was now the default in grub menu. 2) i want to remove/delete/purge 9.04 completely from my system and "clean up" the stuff so that the machine boots straight to 9.10 (no grub menu). how are these accomplished in a "safe" manner? thank you. -denk

• grub/burg listing a lot of os's

  - by Matthew

  I guess I've got more than one ubuntu installation (either two or three) along with a windows 7 installation. Each of the ubuntu installations also list something extra (maybe like a safe mode?) within grub. Firstly, how do I remove the ubuntu installations I don't use? (how do I first identify the one I do use? I log into it after booting it, but how do I delete the others) Also, how do I leave just a Windows 7 option and an Ubuntu option?

• Learning about security and finding exploits

  - by Jayraj

  First things first: I have absolutely no interest in learning how to crack systems for personal enrichment, hurting other people or doing anything remotely malicious. I understand the basis of many exploits (XSS, SQL injection, use after free etc.), though I've never performed any myself. I even have some idea about how to guard web applications from common exploits (like the aforementioned XSS and SQL injection) Reading this question about the Internet Explorer zero-day vulnerability from the Security SE piqued my curiosity and made me wonder: how did someone even find out about this exploit? What tools did they use? How did they know what to look for? I'm wary about visiting hacker dens online for fear of getting my own system infected (the Defcon stories make me paranoid). So what's a good, safe place to start learning?

• Naming the Weapons and Designing Weapons Based in Real-life During Game Development [duplicate]

  - by David Dimalanta

  This question already has an answer here: Do you need a license for weapon models? 6 answers Is it legit or copyright safe if I name the actual name of the gun model such as AK-47, M16, Remington 870, and so on? I'm on the works for making a simple 2D 3rd-person shooter game. One of the examples is the Counter Strike and the game listed the name of weapons based on the real life models and so developers decided to created this named it for the weapon designs. If not, should I make either falsify the name of weapons (e.g. 9mm instead of Glock 17 from a Syphon Filter game) or make fictional weapons like the ones developed behind Halo games?

• TIME column in TOP command for mysql

  - by michael

  When I run top on my database server I get that mysqld has been running for 4:00.51 and it continues to go up. I assume this means that one process with mysql has been running this long from other posts on here. Its not set to cumulative mode as best I can tell as the heading looks like it would change to CTIME if that be the case. What I'm wondering is if this is normal for a site that makes a lot of individual connections using PHP. I shouldn't have any long running processes that would hold on to a mysql connection for this long, only seconds at most. Am I incorrect to assume that this time relates to one connection/process running? I think usually I see it flash up and away on the TOP, not just stay there with this number increasing.

• How is time calculation performed by a computer?

  - by Jorge Mendoza

  I need to add a certain feature to a module in a given project regarding time calculation. For this specific case I'm using Java and reading through the documentation of the Date class I found out the time is calculated in milliseconds starting from January 1, 1970, 00:00:00 GMT. I think it's safe to assume there is a similar "starting date" in other languages so I guess the specific implementation in Java doesn't matter. How is the time calculation performed by the computer? How does it know exactly how many milliseconds have passed from that given "starting date and time" to the current date and time?

• Right click menu stopped working in firefox

  - by umpirsky

  Right click menu stopped working in firefox as well as address bar auto completion. I have tried removing and installing firefox again from software center, but the problem persist. UPDATE: Hehum, strange. I wanted to restart in safe mode, clicked help menu, and noticed that menu is ubuntu software center menu! Then cllosed software center, and menu was gone. So now right click is working, auto complete is working, but there is no main menu! Probably unity global menu integration problem. Also, there is no firefox in launcher nor alt+tab any more. Any idea? UPDATE: For some reason, it works after computer restart :o

• MonoGame; reliable enough to be accepted on iOS, Win 8 and Android stores?

  - by Serguei Fedorov

  I love XNA; it simplifies rendering code to where I don't have to deal with it, it runs on C# and has very fairly large community and documentation. I would love to be able to use it for games across many platforms. However, I am a little bit concerned about how well it will be met by platform owners; Apple has very tight rules about code base but Android does not. Microsoft's new Windows 8 platforms seems to be pretty lenient but I am not sure oh how they would respond to an XNA project being pushed to the app store (given they suddenly decided to dump it and force developers to use C++/Direct3D). So the bottom line is; is it safe to invest time and energy into a project that runs on MonoGame? In the end, is is possible to see my game on multiple platforms and not be shot down with a useless product?

• Set up linux box for hosting a-z

  - by microchasm

  I am in the process of reinstalling the OS on a machine that will be used to host a couple of apps for our business. The apps will be local only; access from external clients will be via vpn only. The prior setup used a hosting control panel (Plesk) for most of the admin, and I was looking at using another similar piece of software for the reinstall - but I figured I should finally learn how it all works. I can do most of the things the software would do for me, but am unclear on the symbiosis of it all. This is all an attempt to further distance myself from the land of Configuration Programmer/Programmer, if at all possible. I can't find a full walkthrough anywhere for what I'm looking for, so I thought I'd put up this question, and if people can help me on the way I will edit this with the answers, and document my progress/pitfalls. Hopefully someday this will help someone down the line. The details: CentOS 5.5 x86_64 httpd: Apache/2.2.3 mysql: 5.0.77 (to be upgraded) php: 5.1 (to be upgraded) The requirements: SECURITY!! Secure file transfer Secure client access (SSL Certs and CA) Secure data storage Virtualhosts/multiple subdomains Local email would be nice, but not critical The Steps: Download latest CentOS DVD-iso (torrent worked great for me). Install CentOS: While going through the install, I checked the Server Components option thinking I was going to be using another Plesk-like admin. In hindsight, considering I've decided to try to go my own way, this probably wasn't the best idea. Basic config: Setup users, networking/ip address etc. Yum update/upgrade. Upgrade PHP/MySQL: To upgrade PHP and MySQL to the latest versions, I had to look to another repo outside CentOS. IUS looks great and I'm happy I found it!
