  • Vernon's book Implementing DDD and modeling of underlying concepts

    - by EdvRusj
    Following questions all refer to examples presented in Implementing DDD In article we can see from Figure 6 that both BankingAccount and PayeeAccount represent the same underlying concept of Banking Account BA 1. On page 64 author gives an example of a publishing organization, where the life-cycle of a book goes through several stages ( proposing a book, editorial process, translation of the book ... ) and at each of those stages this book has a different definition. Each stage of the book is defined in a different Bounded Context, but do all these different definitions still represent the same underlying concept of a Book, just like both BankingAccount and PayeeAccount represent the same underlying concept of a BA? 2. a) I understand why User shouldn't exist in Collaboration Context ( CC ), but instead should be defined within Identity and Access Context IAC ( page 65 ). But still, do User ( IAC ), Moderator ( CC ), Author ( CC ),Owner ( CC ) and Participant ( CC ) all represent different aspects of the same underlying concept? b) If yes, then this means that CC contains several model elements ( Moderator, Author, Owner and Participant ), each representing different aspect of the same underlying concept ( just like both BankingAccount and PayeeAccount represent the same underlying concept of a BA ). But isn't this considered a duplication of concepts ( Evan's book, page 339 ), since several model elements in CC represent the same underlying concept? c) If Moderator, Author ... don't represent the same underlying concept, then what underlying concept does each represent? 3. In an e-commerce system, the term Customer has multiple meanings ( page 49 ): When user is browsing the Catalog, Customer has different meaning than when user is placing an Order. But do these two different definitions of a Customer represent the same underlying concept, just like both BankingAccount and PayeeAccount represent the same underlying concept of a BA? thanks

  • Using IIS7 as a reverse proxy

    - by Jon
    Hi All, My question is pretty much identical to the question listed but they did not get an answer as they ended up using Linux as the reverse proxy. http://serverfault.com/questions/55309/using-iis7-as-a-reverse-proxy I need to have IIS the main site and linux (Apache) being the proxied site(s). so I have site1.com (IIS7) site2.com (Linux Apache) they have subdomains of sub1.site1.com sub2.site1.com sub3.site2.com I want all traffic to go to site1.com and to say anything that is site2.com should be proxied to linux box on internal network, (believe ARR can do this but not sure how). I can not have it running as Apache doing the proxying as I need IIS exposed directly. any and all advice would be great. Thanks

  • Updating Cisco VPN config to add vpnc support

    - by Igor Kuzmitshov
    I have a Cisco 1841 configured for VPN connections of two types: Peer-to-peer for partners' routers (IPsec) — using different crypto isakmp key and crypto map with set peer, set transform-set, match address for every peer (same map name, different priorities). That crypto map name is added to the WAN interface. Client access (PPTP) — using vpdn-group with accept-dialin protocol pptp. Now, a new partner wants to connect using vpnc client. The latter needs IPSec ID (group name) and IPSec secret in addition to username and password. I guess that IPSec secret is pre-shared key that can be specified in crypto isakmp key on Cisco. But I could not find any VPN tutorials involving groups. Hence, my questions: How to add IPSec ID (group name) and IPSec secret on Cisco router for vpnc connections? Should I add a new crypto map matching all addresses as well? Is it possible to add this configuration without breaking the existing setup? Thank you.

  • W2k8 RC1: Windows Media Servers (WMS) as proxy

    - by da_didi
    (fullquote from stackoverflow.com/questions/2690788/w2k8-rc1-windows-media-servers-wms-as-proxy/2690791#2690791) I will have one streaming-server (W2k8, unknown streaming protocol [rtsp, mss, http]) and half dozen streaming-servers as proxies to save bandwidth. I have read the documentation and installed the modules, but I am unsure how I have to configure the proxy's according to http://technet.microsoft.com/de-de/library/ee126142(en-us,WS.10).aspx - as a proxy or reverse proxy and how I minimize the bandwidth needs between origin server and proxy's. What is the best way to realize my setup? Any short how-tos? How can I announce all players to use the proxy? Route all rtsp/mms/http-requests through my proxy? Announce the proxy with DHCP-releases? Thanks!

  • How to change XFCE to LXDE?

    - by kurp
    I've just installed LinuxMint XFCE, which seems to be still a bit to heavy for my hardware. Thus, I'm thinking about LXDE installation and wonder if a new Linux installation is necessary/advised in such case. The question is: how to switch easily? The additional questions are: a) is it necessary to remove the XFCE packages or both DEs may be installed at the same time? b) is there any way to simply switch between DEs (i.e. have both DEs available and boot with DE selected each time)? c) are there any performance consequences of having more than one DE installed? it means: is clean LXDE installation faster than Linux with 2 separate desktops?

  • Adding complexity by generalising: how far should you go?

    - by marcog
    Reference question: http://stackoverflow.com/questions/4303813/help-with-interview-question The above question asked to solve a problem for an NxN matrix. While there was an easy solution, I gave a more general solution to solve the more general problem for an NxM matrix. A handful of people commented that this generalisation was bad because it made the solution more complex. One such comment is voted +8. Putting aside the hard-to-explain voting effects on SO, there are two types of complexity to be considered here: Runtime complexity, i.e. how fast does the code run Code complexity, i.e. how difficult is the code to read and understand The question of runtime complexity is something that requires a better understanding of the input data today and what it might look like in the future, taking the various growth factors into account where necessary. The question of code complexity is the one I'm interested in here. By generalising the solution, we avoid having to rewrite it in the event that the constraints change. However, at the same time it can often result in complicating the code. In the reference question, the code for NxN is easy to understand for any competent programmer, but the NxM case (unless documented well) could easily confuse someone coming across the code for the first time. So, my question is this: Where should you draw the line between generalising and keeping the code easy to understand?

  • European wireless data

    - by drewk
    I am on my way to Europe for 20 days with the wife and teenage kids. Among us, we have 3 iPhones, 1 Blackberry, 2 iPad 3G and 2 Macbook Pro laptops. Each has Skype. I am very concerned about AT&T data charges, and I am looking for a sensible alternative. For example, the AT&T data plans for the phones and iPads are $200 EACH for 200 MB per device. That is $1,200 and does not even cover the laptops. Ouch!!! I am thinking about a prepaid data plan from a European cell system of some sort combined with a GSM data modem and a Cradlepoint router, such as the CTR500. So, questions: 1) Anyone know of a GSM data source in Europe where I can buy a GSM Modem compatible with the CTR500 at a reasonable prepaid rate? 2) Experience with the CTR500?

  • text extraction from video game dialogue files [on hold]

    - by wdwvt1
    As part of an academic project, I am trying to access the dialogue files (whether audio or text) from a variety of sports video games (Madden or NBA 2kX would be fantastic). I have searched extensively on other sites (scholarly text-mining publications, r/gaming, r/madden, modding sites, etc.) for guidance in how to extract dialogue files, but have been unsuccessful. Given that I don't have even the domain specific language to ask the right question (i.e. the resources I am seeking are out there, I just can't find them) I am asking the SE game dev community for help with the 2 following questions: Is there a canonical resource that I should study that would get me started with how to extract text or audio files from games? I am very fluent in python, which usually excels at mining information from sources, but I struggle with knowing where to start with a video game (as opposed to a more familiar database with a defined API). Is this even feasible, or are protections included with newer games (e.g. NBA 2k13) going to make extraction of these resources in a programmatic way impossible? Thank you for your help!

  • need for tcp fine-tuning on heavily used proxy server

    - by Vijay Gharge
    Hi all, I am using squid like Internet proxy server on RHEL 4 update 6 & 8 with quite heavy load i.e. 8k established connections during peak hour. Without depending much on application provider's expertise I want to achieve maximum o/p from linux. W.r.t. that I have certain questions as following: How to find out if there is scope for further tcp fine-tuning (without exhausting available resources) as the benchmark values given by vendor looks poor! Is there any parameter value that is available from OS / network stack that will show me the results. If at all there is scope, how shall I identify & configure OS tcp stack parameters i.e. using sysctl or any specific parameter Post tuning how shall I clearly measure performance enhancement / degradation ?

  • .Net search engine architecture and technology choice

    - by shrivb
    I am in the process of designing a search engine for an asp.net site. The site currently uses Microsoft Indexing Server to index and search content which range from simple text files to MS documents to PDFs. MIS is also used to crawl File servers. MIS in tandem with Index Server Companion crawls for content from external sites. I intend to replace MIS with the indexer/crawler I am trying to build. Since my platform is completely on the Microsoft stack, I cant afford to have a Java application server. Thus, Solr, and effectively, SolrNet is ruled out. With this being the context, I have couple of questions. 1.Technology choice I had done my initial investigation and looked at Lucene.Net. There seemed to be 2 issues in using Lucene.Net. First being, it cant crawl external content. There doesn't seem to be a direct port of Nutch in .Net. Second, since it is just an indexer, it cant parse various document types. The parsing is left to the developer. So, what would be best technology choice on the .Net platform to achieve indexing & crawling? Are there any .Net open source libraries available for document parsing? 2.Architectural pattern Is there any general architectural pattern or best practice that needs to be followed in designing such a search engine? Thanks in advance.

The Path from a Social Brand to a Social Business Brian Solis Originally posted May 2, 2012 I’ve been a long-time supporter of MediaTemple’s (MT)Residence program along with Gary Vaynerchuk, Neil Patel, and many others whom I respect. I wanted to share my “7 questions to answer to become a social business” with you here.. Social Media is pervasive and is becoming the new normal in corporate marketing. Brands who get this right are starting to build their own media networks rich with customer connections numbering in the millions. Right now, Coca-Cola has over 34 million fans on Facebook, but they’re hardly alone. Disney follows just behind with 29 million fans, Starbucks boasts 25 million, and Oreo, Red Bull, and Converse play host to over 20 million fans. If we were to look at other networks such as Twitter and Youtube, we would see a recurring theme. People are connecting en masse with the businesses they support and new media represents the ability to cultivate consumer relationships in ways not possible with traditional earned or paid media. Sounds great right? This might sound abrupt, but the truth is that we’re hardly realizing the potential of what lies before us. Everything begins with understanding not just how other brands are marketing themselves in social media, but also seeing what they’re not doing and envisioning what’s possible. We’re already approaching the first of many crossroads that new media will present. Do we take the path of a social brand or that of a social business? What’s the difference? A social brand is just that, a business that is remodeling or retrofitting its existing marketing practices to new media. A social business is something altogether different as it embraces introspection and extrospection to reevaluate internal and external processes, systems, and opportunities to transform into a living, breathing entity that adapts to market conditions and opportunities. It’s a tough decision to make right now especially at a time when all we read about is how much success many businesses are finding without having to answer this very question. With all of the newfound success in social networks, the truth is that we’re only just beginning to learn what’s possible and that’s where you come in. When compared to the investment in time and resources across the board, social media represents only a small part of the mix. But with your help, that’s all about to change. The CMO Survey, an organization that disseminates the opinions of top marketers in order to predict the future of markets, recently published a report that gave credence to the fact that social media is taking off. One of the most profound takeaways from the report was this gem; “The “like button” [in Facebook] packs more customer-acquisition punch than other demand-generating activities.” With insights like this, it’s easy to see why the race to social is becoming heated. The report also highlighted exactly where social fits in the marketing mix today and as you can see, despite all of the hype, it’s not a dominant focus yet. As of August 2011, the percentage of overall marketing budgets dedicated to social media hovered at around 7%. However, in 2012 the investment in social media will climb to 10%. And, in five years, social media is expected to represent almost 18% of the total marketing budget. Think about that for a moment. In 2016, social media will only represent 18%? Queue the sound of a record scratching here. With businesses finding success in social networks, why are businesses failing to realize the true opportunity brought forth by the ability to listen to, connect with, and engage with customers? While there’s value in earning views, driving traffic, and building connections through the 3F’s (friends, fans and followers), success isn’t just defined simply by what really amounts to low-hanging fruit. The truth is that businesses cannot measure what it is they don’t know to value. As a result, innovation in new engagement initiatives is stifled because we’re applying dated or inflexible frameworks to new paradigms. Social media isn’t owned by marketing, but instead the entire organization. This changes everything and makes your role so much more important. It’s up to you to learn how to think outside of the proverbial social media box to see what others don’t, the ability to improve customers experiences through the evolution of a social brand into a social business. Doing so will translate customer insights from what they do and don’t share in social networks into better products, services, and processes. See, customers want something more from their favorite businesses than creative campaigns, viral content, and everyday dialogue in social networks. Customers want to be heard and they want to know that you’re listening. How businesses use social media must remind them that they’re more than just an audience, consumer, or a conduit to “trigger” a desired social effect. Herein lies both the challenge and opportunity of social media. It’s bigger than marketing. It’s also bigger than customer service. It’s about building relationships with customers that improve experiences and more importantly, teaches businesses how to re-imagine products and internal processes to better adapt to potential crises and seize new opportunities. When it comes down to it, Twitter, Facebook, Youtube, Foursquare, are all channels for listening, learning, and engaging. It’s what you do within each channel that builds a community around your brand. And, at the end of the day, the value of the community you build counts for everything. It’s important to understand that we cannot assume that these networks simply exist for people to lineup for our marketing messages or promotional campaigns. Nor can we assume that they’re reeling in anticipation for simple dialogue. They want value. They want recognition. They want access to exclusive information and offers. They need direction, answers and resolution. What we’re talking about here is the multidimensional makeup of consumers and how a one-sided approach to social media forces the needs for social media to expand beyond traditional marketing to socialize the various departments, lines of business, and functions to engage based on the nature of the situation or opportunity. In the same CMO study, it was revealed that marketers believe that social media has a long way to go toward integrating into the overall company strategy. On a scale of 1-7, with one being “not integrated at all” and seven being “very integrated,” 22% chose “one.” Critical functions such as service, HR, sales, R&D, product marketing and development, IR, CSR, etc. are either not engaged or are operating social media within a silo disconnected from other efforts or possibilities. The problem is that customers don’t view a company by silo, instead they see one company, one brand, and their experience in social media forms an impression that eventually contributes to their view of your brand. The first step here is to understand business priorities and objectives to assess how social media can be additive in achieving these goals. Additionally, surveying the landscape to determine other areas of interest as its specifically related to your business. • Are customers seeking help or direction? • Who are your most valuable customers and what are they sharing? • How can you use social media to acquire and retain customers? - What ideas are circulating and how can you harness user generated activity and content to innovate or adapt to better meet the needs of customers? - How can you broaden a single customer view to recognize the varying needs of customers and how your organization can organize around each circumstance? - What insights exist based on how consumers are interacting with one another? How can this intelligence inform marketing, service, products and other important business initiatives? - How can your business extend their current efforts to deliver better customer experiences and in turn more effectively unit internal collaboration and communication? Customer demands far exceed the capabilities of the marketing department. While creating a social brand is a necessary endeavor, building a social business is an investment in customer relevance now and over time. Beyond relevance, a social business fosters a culture of change that unites employees and customers and sets a foundation for meaningful and beneficial relationships. Innovation, communication, and creativity are the natural byproducts of engagement and transformation. As a social brand, we are competing for the moment. As a social business, we are competing the future in all that we do today.

  • Should a programmer "think" for the client?

    - by P.Brian.Mackey
    I have gotten to the point where I hate requirements gathering. Customer's are too vague for their own good. In an agile environment, where we can show the client a piece of work to completion it's not too bad as we can make small regular corrections/updates to functionality. In a "waterfall" type in environment (requirements first, nearly complete product next) things can get ugly. This kind of environment has led me to constantly question requirements. E.G. Customer wants "automatically convert input to the number 1" (referring to a Qty in an order). But what they don't think about is that "input" could be a simple type-o. An "x" in a textbox could be a "woops" not I want 1 of those "toothpaste" products. But, there's so much in the air with requirements that I could stand and correct for hours on end smashing out what they want. This just isn't healthy. Working for a corporation, I could try to adjust the culture to fit the agile model that would help us (no small job, above my pay grade). Or, sweep ugly details under the rug and hope for the best. Maybe my customer is trying to get too close to the code? How does one handle the problem of "thinking for the client" without pissing them off with too many questions?

  • 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.)

  • apt-get update very slow, stuck at "Waiting for headers"

    - by Liam
    I have looked at similar questions: Stuck at 0% [waiting for headers] (apt) apt-get update stuck on "Waiting for Headers" However neither one of them answer my problem. I am running 12.04 AMD64 and have recently started getting an issue that when I update my repos from my connection at home through a terminal, using sudo apt-get update, it takes forever (literally after 2 hours it was at 28%), however when I run from a different location it takes less than 5 minutes to complete. I have attempted changing which mirror I use but that does not solve the issue. I have also cut down what is in my sources list but this also makes no difference. There are no faults on my ADSL line as I have already contacted my ISP to check this. It also makes no difference if I use a WiFi or network cable connection. What could be my issue? A speed test (www.speedtest.net) comes out at about 0.9 Mbps down and 0.42 Mbps up (which is a shade under the advertised line speed), I reside in South Africa and use the UCT LEG server. But I have also tried the other mirrors available in SA....none of them make a difference.

  • Interesting sessions/tips from RMOUG

    - by jean-pierre.dijcks
    One of the sessions I was at at last week's RMOUG was a session on Temp Tablespace Groups. I had a look because I had no experience with this and it seemed to help with parallel processing and the allocation/usage of temp. You can read the excellent write-up at Kellyn Pedersen's blog - who did the session and all the work - here. So for all of those who may be seeing lot's of waits like enq: TS - Contention when you are doing hash joins and sorts, do have a look at the above blog post. I also had the chance to listen in at Stewart Bryson's session on Restartability (he had 3 R-s) where he gave very useful tips about how to deal with your data warehouse loads. Questions like archive log mode - should I or should I not were well covered. Flashback archives, also nice to hear about. Very nice talk, very interesting. Unfortunately he hasn't blogged about it yes, so no pointers to that one. Got to see a couple of other interesting sessions, and as conferences go got to meet some interesting Oracle folks from the region. As usual RMOUG was useful and fun. Off to the drawing boards to design next year's session!

  • Boot existing ubuntu installation on uefi, GPT BTRFS

    - by user204720
    I have looked through many of the questions, and haven't found anything that quite satisfies this problem. I have an ssd hard drive that is bootable from my old computer. It is a standard BIOS, however, I built a new computer with Z87 motherboard that is a UEFI. What I'd like to do is boot from this hard drive without wiping out the hard drive. I've tried booting from legacy mode, doesn't seem to work. Part of the multitude of problems is my partitioning scheme, which is GPT. sdx1 is the btrfs system, sdx2 swap, sdx3 is bios_grub. I've tried setting the UEFI/BIOS to boot in legacy mode, I've tried turning my swap partition into a Grub EFI boot, I've tried copying the file system onto a new drive installed on the new system. However, copying the information doesn't keep the filesystem or subvolumes intact. I've also tried boot-repair which is when I overwrote the swap space. I'd really rather not start over on a new install, so any other suggested trees to bark up would be appreciated. For the record, I hate you Microsoft, and ASUS I understand complying with microsoft, but make it optional... I'm really disappointed in that I have to deal with Windows 8 when I have nothing to do with it. Something I think I could try, but would like to hear from more experienced users. Moving the sdx1 (btrfs /@/@home) partion and opening up a 100 MB partition on the beginning sectors and install efi compatible Grub2 installation. Would it work? How to move a partition?

  • Which is the best free ide/plugin for struts2?

    - by shahensha
    Hello friends, I have just learnt struts 2 and now I have taken up a full fledged project in it. I learnt the basics of struts 2 in Netbeans with it's struts2 plugin. But I am not at all happy with it, as it is very basic and I end up doing most of the work. It is obviously better than plain-vanilla text editor, but still not at all near to what netbeans provides for springs and hibernate. I know because netbeans provides native support for springs and hibernate, it is meant to be better. I don't mind changing my IDE if i get better support for struts2! So my questions are Please list all the free IDEs where native support for struts2 is provided. And if possible please compare them. Please list all the plugins that are available for eclipse for struts2 development. I have heard there are better plugins in eclipse. Also, if there are better plugins in any other IDE (other than netbeans or eclipse of course), please list them giving links. Please give me some tips which I'll need before starting a full blown project in Struts2. I haven't worked on any project on Struts2. I have just finished reading Struts 2 in Action of Manning publications. Thanking you in advance! regards shahensha

  • Why Is Hibernation Still Used?

    - by Jason Fitzpatrick
    With the increased prevalence of fast solid-state hard drives, why do we still have system hibernation? Today’s Question & Answer session comes to us courtesy of SuperUser—a subdivision of Stack Exchange, a community-driven grouping of Q&A web sites. The Question SuperUser reader Moses wants to know why he should use hibernate on a desktop machine: I’ve never quite understood the original purpose of the Hibernation power state in Windows. I understand how it works, what processes take place, and what happens when you boot back up from Hibernate, but I’ve never truly understood why it’s used. With today’s technology, most notably with SSDs, RAM and CPUs becoming faster and faster, a cold boot on a clean/efficient Windows installation can be pretty fast (for some people, mere seconds from pushing the power button). Standby is even faster, sometimes instantaneous. Even SATA drives from 5-6 years ago can accomplish these fast boot times. Hibernation seems pointless to me [on desktop computers] when modern technology is considered, but perhaps there are applications that I’m not considering. What was the original purpose behind hibernation, and why do people still use it? Quite a few people use hibernate, so what is Moses missing in the big picture? The Answer SuperUser contributor Vignesh4304 writes: Normally hibernate mode saves your computer’s memory, this includes for example open documents and running applications, to your hard disk and shuts down the computer, it uses zero power. Once the computer is powered back on, it will resume everything where you left off. You can use this mode if you won’t be using the laptop/desktop for an extended period of time, and you don’t want to close your documents. Simple Usage And Purpose: Save electric power and resuming of documents. In simple terms this comment serves nice e.g (i.e. you will sleep but your memories are still present). Why it’s used: Let me describe one sample scenario. Imagine your battery is low on power in your laptop, and you are working on important projects on your machine. You can switch to hibernate mode – it will result your documents being saved, and when you power on, the actual state of application gets restored. Its main usage is like an emergency shutdown with an auto-resume of your documents. MagicAndre1981 highlights the reason we use hibernate everyday: Because it saves the status of all running programs. I leave all my programs open and can resume working the next day very easily. Doing a real boot would require to start all programs again, load all the same files into those programs, get to the same place that I was at before, and put all my windows in exactly the same place. Hibernating saves a lot of work pulling these things back up again. It’s not unusual to find computers around the office here that have been hibernated day in and day out for months without an actual full system shutdown and restart. It’s enormously convenient to freeze your work space at the exact moment you stopped working and to turn right around and resume there the next morning. Have something to add to the explanation? Sound off in the the comments. Want to read more answers from other tech-savvy Stack Exchange users? Check out the full discussion thread here.

  • load langs.xml failed also after fix.

    - by Remy
    I have the same error as stated on: http://superuser.com/questions/67128/notepad-load-langs-xml-failed. I have also applied the fix listed there. I delete the langs.xml file. Then when I reboot notepad++.exe a new langs.xml is created from the langs.model.xml file. However, after I reboot my computer the langs.xml file is corrupted again. It is completely empty. Does anyone know what is causing the deletion of the langs.xml file? I noticed the problem shortly after using windows 7 64 bit, and on two seperate computers.
