• Business case for decentralized version control systems

  - by Keyo

  I searched and couldn't find any business reasons why git/mercurial/bazzr systems are better than centralized systems (subversion, perforce). If you were trying to sell a DVCS to a non-technical person what arguments would you provide for the DVCS increasing profit. I will shortly be pitching git to my manager, it will take some time converting out subversion repositories and some expense in buying smartgit licences.

• Algorithm for performing decentralized search in social networks

  - by Jack

  I want to find out all the existing decentralized algorithms that exploit the structural properties of social networks. So far I know the following algorithms - 1) Best connected search - Adamic et al 2) Random Walk (does not exploit any structural property but still it is decentralized) 3) Hamming distance search 4) Weak/Strong tie search Any help would be appreciated

• Puppet Decentralized Setup

  - by paul.tw

  I want to migrate my existing Puppet setup from master/client to a decentralized solution. I know other solutions, such as Ansible are easier to setup for that purpose, but I really want to stay with Puppet. I found "supply_drop"(https://github.com/pitluga/supply_drop) on github, so I followed the instructions and did the following: rvm gemset create testing rvm use 1.9.3@testing gem install supply_drop The output is the following: [m@ms-MacBook-Pro:~ $ irb 1.9.3-p547 :001 require 'supply_drop' NameError: uninitialized constant Capistrano from /Users/m/.rvm/gems/ruby-1.9.3-p547@testing/gems/supply_drop-0.17.0/lib/supply_drop/tasks.rb:1:in `' from /Users/m/.rvm/rubies/ruby-1.9.3-p547/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:55:in `require' from /Users/m/.rvm/rubies/ruby-1.9.3-p547/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:55:in `require' from /Users/m/.rvm/gems/ruby-1.9.3-p547@testing/gems/supply_drop-0.17.0/lib/supply_drop.rb:10:in `' from /Users/m/.rvm/rubies/ruby-1.9.3-p547/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:135:in `require' from /Users/m/.rvm/rubies/ruby-1.9.3-p547/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:135:in `rescue in require' from /Users/m/.rvm/rubies/ruby-1.9.3-p547/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:144:in `require' from (irb):1 from /Users/m/.rvm/rubies/ruby-1.9.3-p547/bin/irb:12:in `' Since that doesn't work without problems, I was wondering which alternatives are there available to do the same. Do you have any suggestings?

• Using git with cgit for decentralized/centralized development

  - by polemon

  I plan to use git for hosting my projects on my server. I've read about cgit, git-daemon, and I more or less decided to use those tools. But general use is still kind of confusing for me. What do I need to set up on the server, to push my files onto it. And when the files on the server are newer as the files on my computer, how do I merge them? Also, I use, say, two computers where I develop. How do I merge from one computer to the other? Also, when two people are working on the same project, how do they merge their local repos from one another? As you probably can tell by now, I come from SVN, but I've worked with Mercurial and now I'd like to test git.

• Concept of GUI's - Centralized or decentralized

  - by wvd

  Hello all, Since a few months I've been learning Erlang, and now it was time to do some basic GUI. After some quick research I saw there was an interesting library called 'wxi' (based on Fudgets of Haskell) which uses a different approach on GUI's. No central loop, every widget processes it's own events and handles it's own data. What do you guys think about this? It looks like it kind of can be efficient in languages such as Erlang, and it's an interesting approach. William van Doorn

• Decentralized synchronized secure data storage

  - by Alberich

  Introduction Hi, I am going to ask a question which seems utopic for me, but I need to know if there is a way to achieve what I need. And if not, I need to know why not. The idea Suppose I have a database structure, in MySql. I want to create some solution to allow anyone (no matter who, no matter where) to have a synchronized copy (updated clone) of this database (with its content) Well, and it is not going to be just one synchronized copy, it could (and should) be a multiple replication (supposing the basic, this means, for example, ten copies all over the world) And, the most important thing: It must be secure. By secure I mean only real-accepted transactions will be synchronized with all the others (no matter how many) database copies/clones. Note: Since it would be quite difficult to make the synchronization in real-time, I will design everything to make this feature dispensable. So it is not required. My auto-suggestion This is how I am thinking to manage it: Time identifiers and Updates checking: Every action (insert, update, delete...) will be stored as the action instruction itself, associated to the time identifier. [I think better than a DATETIME field, it'll be an INT one, with the number of miliseconds passed from 1st january 2013 on, for example]. So each copy is going to ask to the "neighbour copy" for new actions done since last update, and execute them after checking they are allowed. Problem 1: the "neighbour copy" could be outdated too. Solution 1: do not ask just one neighbour, create a random list with some of the copies/clones and ask them for news (I could avoid the list and ask ALL the clones for updates, but this will be inefficient if clones number ascends too much). Problem 2: Real-time global synchronization is not active. What if... Someone at CLONE_ENTERPRISING inserts a row into TABLE. ... this row goes to every clone ... Someone at CLONE_FIXEMALL deletes this row. ... and at the same time, somewhere in an outdated clone ... Someone at CLONE_DROPOUT edits this row (now inexistent at the other clones) Solution 2: easy stuff, force a GLOBAL synchronization before doing any new "depending-on-third-data action" (edit, for example). This global synch. will be unnecessary when making an INSERT, for instance. Note: Well, someone could have some fun, and make the same insert in two clones... since they're not getting updated in real-time, this row will exist twice. But, it's the same as when we have one single database, in some needed cases we check if there is an existing same-row before doing the final action. Not a problem. Problem 3: It is possible to edit the code and do not filter actions, so someone could spread instructions to delete everything, or just make some trolling activity. This is not a problem, since good clones will always be somewhere. Those who got bad won't interest anymore. I really appreciate if you read. I know this is not the perfect solution, it has possibly hundred of holes, but it is my basic start. I will now appreciate anything you can teach me now. Thanks a lot. PS.: It could be that all this I am trying already exists and has its own name. Sorry for asking then (I'd anyway thank this name, if it exists)

• Decentralized Chat feature in C#/WPF?

  - by Jim Beam

  What are some options for implementing a chat feature in a C#/WPF desktop application? Is it possible to do this without a central server? I have a desktop app and 1 user may be logged in at one time or 50 users may be logged in. I would like to add a chat feature that will allow them to talk to each other without relying on a central server. If I do have to use a central server, I assume that WCF would be the best option? Are there any solid examples of this with WCF?

• decentralized development using git and git-svn

  - by CantGetANick

  We have 2-3 small teams of 2-3 people. We all use git for local and svn for central repository and git-svn got sync. This is works all the time except when we want to share our code between the team it self. So we have tried out git pull, this creates lots of conflicts and it does not detect that we are on the same tree. It fetches all the changes (same as clone then pull) Of course i dont want to clone full repo. every time I want to share. Please suggest a better flow. We can't get rid of central svn. We can't clone every time.

• Data synchronization using XMPP

  - by Jason

  Hi: I'm looking for some insight/advice on synchronizing data over XMPP. I've never developed anything for XMPP before so excuse me if some of my questions seem ridiculous. Basically, what I have is a decentralized social network. Each person has it's own Web site (or server) with a unique URI (one domain could host many servers). Each of these servers can have many clients. E.g., a desktop application, mobile application, etc. What I would like to accomplish is near real-time synchronization/communication between client and server, e.g., I update something on my desktop application, I see it change on my Web site. My server and client code is Python. So, I would like to make use of SleekXMPP if possible (it's license seems to have changed to MIT). I was thinking, and here is where I need advice, that each server would register an account at a dedicated XMPP server, e.g., [email protected]. and then I could use different resources for clients [email protected]/client1, [email protected]/client2, etc. If anyone can register any username, then maybe I also need some intermediate service (since it's decentralized, i'm not sure how to control registrations). Another option, I guess, is that each server runs it's own xmpp server. Assuming, that was all worked out, if I want to broadcast messages to all my resources (except the sending one), how do I do that? Do I have to subscribe to myself? This also seems like a good candidate for publish-subscribe, let me know if you think that could work and what the design/flow of that process would be. thanks :)

• Does any faster centralized version control than SVN exists?

  - by Savageman

  Hello, I've been using SVN since a long time and now we're trying on Git. I'm not talking on the centralized / decentralized debate here. My only concern is speed. The latter tool is much faster. But sometimes, I NEED to work with a centralized approach, which is much more simple and less complex than the decentralized one. The learning curve is really fast, which saves a lot of time (while digging into decentralized would lead to a waste of time, given the learning curve is much longer and we encounter more problem when working with it). However, SVN is really slow compared to GIT, and I don't think it has anything to do with the centralized argument. Decentralized systems also have to deal with server connections and file transfert. So I can easilly imagine a faster implementation of centralized version control could exists. Does someone has any clue on this?

• Improve Microsoft Visual C++ Application Security and Robustness with SafeInt

  In this age of cloud computing, massive parallel systems and complex security threats like identity theft and decentralized botnets, devoting resources to combat the seemingly age-old issue of integer overflow appears distinctly passC). Despite the fact that integer overflow is such a well know problem, particularly within C and C++ programming, the problem remains a real issue from both a defect and security standpoint, that's why the introduction of the SafeInt template class in Visual C++ 2010 to address overflows is a great addition.

• SQL SERVER – Weekend Project – Experimenting with ACID Transactions, SQL Compliant, Elastically Scalable Database

  - by pinaldave

  Database technology is huge and big world. I like to explore always beyond what I know and share the learning. Weekend is the best time when I sit around download random software on my machine which I like to call as a lab machine (it is a pretty old laptop, hardly a quality as lab machine) and experiment it. There are so many free betas available for download that it’s hard to keep track and even harder to find the time to play with very many of them.  This blog is about one you shouldn’t miss if you are interested in the learning various relational databases. NuoDB just released their Beta 7.  I had already downloaded their Beta 6 and yesterday did the same for 7.   My impression is that they are onto something very very interesting.  In fact, it might be something really promising in terms of database elasticity, scale and operational cost reduction. The folks at NuoDB say they are working on the world’s first “emergent” database which they tout as a brand new transitional database that is intended to dramatically change what’s possible with OLTP.  It is SQL compliant, guarantees ACID transactions, yet scales elastically on heterogeneous and decentralized cloud-based resources. Interesting note for sure, making me explore more. Based on what I’ve seen so far, they are solving the architectural challenge that exists between elastic, cloud-based compute infrastructures designed to scale out in response to workload requirements versus the traditional relational database management system’s architecture of central control. Here’s my experience with the NuoDB Beta 6 so far: First they pretty much threw away all the features you’d associate with existing RDBMS architectures except the SQL and ACID transactions which they were smart to keep.  It looks like they have incorporated a number of the big ideas from various algorithms, systems and techniques to achieve maximum DB scalability. From a user’s perspective, the NuoDB Beta software behaves like any other traditional SQL database and seems to offer all the benefits users have come to expect from standards-based SQL solutions. One of the interesting feature is that one can run a transactional node and a storage node on my Windows laptop as well on other platforms – indeed interesting for sure. It’s quite amazing to see a database elastically scale across machine boundaries. So, one of the basic NuoDB concepts is that as you need to scale out, you can easily use more inexpensive hardware when/where you need it.  This is unlike what we have traditionally done to scale a database for an application – we replace the hardware with something more powerful (faster CPU and Disks). This is where I started to feel like NuoDB is on to something that has the potential to elastically scale on commodity hardware while reducing operational expense for a big OLTP database to a degree we’ve never seen before. NuoDB is able to fully leverage the cloud in an asynchronous and highly decentralized manner – while providing both SQL compliance and ACID transactions. Basically what NuoDB is doing is so new that it is all hard to believe until you’ve experienced it in action.  I will keep you up to date as I test the NuoDB Beta 7 but if you are developing a web-scale application or have an on-premise app you are thinking of moving to the cloud, testing this beta is worth your time. If you do try it, let me know what you think.  Before I say anything more, I am going to do more experiments and more test on this product and compare it with other existing similar products. For me it was a weekend worth spent on learning something new. I encourage you to download Beta 7 version and share your opinions here.

• How to Set Up Your Enterprise Social Organization

  - by Mike Stiles

  The rush for business organizations to establish, grow, and adopt social was driven out of necessity and inevitability. The result, however, was a sudden, booming social presence creating touch points with customers, partners and influencers, but without any corporate social organization or structure in place to effectively manage it. Even today, many business leaders remain uncertain as to how to corral this social media thing so that it makes sense for their enterprise. Imagine their panic when they hear one of the most beneficial approaches to corporate use of social involves giving up at least some hierarchical control and empowering employees to publicly engage customers. And beyond that, they should also be empowered, regardless of their corporate status, to engage and collaborate internally, spurring “off the grid” innovation. An HBR blog points out that traditionally, enterprise organizations function from the top down, and employees work end-to-end, structured around business processes. But the social enterprise opens up structures that up to now have not exactly been embraced by turf-protecting executives and managers. The blog asks, “What if leaders could create a future where customers, associates and suppliers are no longer seen as objects in the system but as valued sources of innovation, ideas and energy?” What if indeed? The social enterprise activates internal resources without the usual obsession with position. It is the dawn of mass collaboration. That does not, however, mean this mass collaboration has to lead to uncontrolled chaos. In an extended interview with Oracle, Altimeter Group analyst Jeremiah Owyang and Oracle SVP Reggie Bradford paint a complete picture of today’s social enterprise, including internal organizational structures Altimeter Group has seen emerge. One sign of a mature social enterprise is the establishing of a social Center of Excellence (CoE), which serves as a hub for high-level social strategy, training and education, research, measurement and accountability, and vendor selection. This CoE is led by a corporate Social Strategist, most likely from a Marketing or Corporate Communications background. Reporting to them are the Community Managers, the front lines of customer interaction and engagement; business unit liaisons that coordinate the enterprise; and social media campaign/product managers, social analysts, and developers. With content rising as the defining factor for social success, Altimeter also sees a Content Strategist position emerging. Across the enterprise, Altimeter has seen 5 organizational patterns. Watching the video will give you the pros and cons of each. Decentralized - Anyone can do anything at any time on any social channel. Centralized – One central groups controls all social communication for the company. Hub and Spoke – A centralized group, but business units can operate their own social under the hub’s guidance and execution. Most enterprises are using this model. Dandelion – Each business unit develops their own social strategy & staff, has its own ability to deploy, and its own ability to engage under the central policies of the CoE. Honeycomb – Every employee can do social, but as opposed to the decentralized model, it’s coordinated and monitored on one platform. The average enterprise has a whopping 178 social accounts, nearly ¼ of which are usually semi-idle and need to be scrapped. The last thing any C-suite needs is to cope with fragmented technologies, solutions and platforms. It’s neither scalable nor strategic. The prepared, effective social enterprise has a technology partner that can quickly and holistically integrate emerging platforms and technologies, such that whatever internal social command structure you’ve set up can continue efficiently executing strategy without skipping a beat. @mikestiles

• Modular Open MMO RPG

  - by Chris Valentine

  Has there been an MMORPG type attempt at some kind of open universe where you could host a server on your own if you wish and it would merely be added to the collective of possible places to travel within the MMO? Two types come to mind, a DnD Neverwinter Nights type place or something like EVE online. Where there is a "universe" and each hosted space is a planet or solar system or galaxy and players can travel between them using the same characters/ships/portal system and each new server is than just a new adventure or place to go. I would also assume there were dedicated/replicated servers that housed the characters/inventory themselves so that the environment was decentralized and always expandable. Not sure thats clear but has there been any such attempts or WIP? thanks

• PeopleSoft at Alliance 2012 Executive Forum

  - by John Webb

  Guest Posting From Rebekah Jackson This week I jointed over 4,800 Higher Ed and Public Sector customers and partners in Nashville at our annual Alliance conference.   I got lost easily in the hallways of the sprawling Gaylord Opryland Hotel. I carried the resort map with me, and I would still stand for several minutes at a very confusing junction, studying the map and the signage on the walls. Hallways led off in many directions, some with elevators going down here and stairs going up there. When I took a wrong turn I would instantly feel stuck, lose my bearings, and occasionally even have to send out a call for help.    It strikes me that the theme for the Executive Forum this year outlines a less tangible but equally disorienting set of challenges that our higher education customer’s CIOs are facing: Making Decisions at the Intersection of Business Value, Strategic Investment, and Enterprise Technology. The forces acting upon higher education institutions today are not neat, straight-forward decision points, where one can glance to the right, glance to the left, and then quickly choose the best course of action. The operational, technological, and strategic factors that must be considered are complex, interrelated, messy…and the stakes are high. Michael Horn, co-author of “Disrupting Class: How Disruptive Innovation Will Change the Way the World Learns”, set the tone for the day. He introduced the model of disruptive innovation, which grew out of the research he and his colleagues have done on ‘Why Successful Organizations Fail’. Highly simplified, the pattern he shared is that things start out decentralized, take a leap to extreme centralization, and then experience progressive decentralization. Using computers as an example, we started with a slide rule, then developed the computer which centralized in the form of mainframes, and gradually decentralized to mini-computers, desktop computers, laptops, and now mobile devices. According to Michael, you have more computing power in your cell phone than existed on the planet 60 years ago, or was on the first rocket that went to the moon. Applying this pattern to Higher Education means the introduction of expensive and prestigious private universities, followed by the advent of state schools, then by community colleges, and now online education. Michael shared statistics that indicate 50% of students will be taking at least one on line course by 2014…and by some measures, that’s already the case today. The implication is that technology moves from being the backbone of the campus, the IT department’s domain, and pushes into the academic core of the institution. Innovative programs are underway at many schools like Bellevue and BYU Idaho, joined by startups and disruptive new players like the Khan Academy.   This presents both threat and opportunity for higher education institutions, and means that IT decisions cannot afford to be disconnected from the institution’s strategic plan. Subsequent sessions explored this theme.    Theo Bosnak, from Attain, discussed the model they use for assessing the complete picture of an institution’s financial health. Compounding the issue are the dramatic trends occurring in technology and the vendors that provide it. Ovum analyst Nicole Engelbert, shared her insights next and suggested that incremental changes are no longer an option, instead fundamental changes are affecting the landscape of enterprise technology in higher ed.    Nicole closed with her recommendation that institutions focus on the trends in higher education with an eye towards the strategic requirements and business value first. Technology then is the enabler.   The last presentation of the day was from Tom Fisher, Sr. Vice President of Cloud Services at Oracle. Tom runs the delivery arm of the Cloud Services group, and shared his thoughts candidly about his experiences with cloud deployments as well as key issues around managing costs and security in cloud deployments. Okay, we’ve covered a lot of ground at this point, from financials planning, business strategy, and cloud computing, with the possibility that half of the institutions in the US might not be around in their current form 10 years from now. Did I forget to mention that was raised in the morning session? Seems a little hard to believe, and yet Michael Horn made a compelling point. Apparently 100 years ago, 8 of the top 10 education institutions in the world were German. Today, the leading German school is ranked somewhere in the 40’s or 50’s. What will the landscape be 100 years from now? Will there be an institution from China, India, or Brazil in the top 10? As Nicole suggested, maybe US parents will be sending their children to schools overseas much sooner, faced with the ever-increasing costs of a US based education. Will corporations begin to view skill-based certification from an online provider as a viable alternative to a 4 year degree from an accredited institution, fundamentally altering the education industry as we know it?

• Advantages of Client/Server Architecture over Mainframe Architecture

  Originally mainframe architectures relied on a centralized host server that processed data and returned it to be displayed on a dummy terminal. These dummy terminals did not have my processing power and could only display data that was sent from the mainframe. Application architecture completely changed with the advent of N-Tier architecture. The N-Tier architecture replaced the dummy terminals with standard PCs that could think and/or process for themselves. This allowed for applications to be decentralized. Further, this type of architecture also breaks up the roles found within a mainframe by extracting Web Interfaces, Application Logic and Data access in to 3 separate parts so that it can be extended and distributed as the demands of an application increases.

• Best distributed version control system?

  - by afsharm

  I have been using SourceSafe and Subversion for years, but recently decided to choose a distributed version control system (or decentralized source control management) like Git, Mercurial or Bazaar or any other thing. So what is best of them? I'm a Windows/Visual Studio user.

• users authentication and dht

  - by mtasic

  Lets say that I have only DHT (distributed hash table) implemented (in Python), and I want to build authentication service over P2P network, but without introducing centralized authentication server with such a service. Can it be done, and if so how can I achieve this? I'm familiar with how Skype and Wuala have done this, but I am looking for decentralized solution without single point of failure.
