• Are today's general purpose languages at the right level of abstraction ?

  - by KeesDijk

  Today Uncle Bob Martin, a genuine hero, showed this video In this video Bob Martin claims that our programming languages are at the right level for our problems at this time. One of the reasons I get from this video as that Bob Martin sees us as detail managers and our problems are at the detail level. This is the first time I have to disagree with Bob Martin and was wondering what the people at programmers think about this. First there is a difference between MDA and MDE MDA in itself hasn't worked and I blame way to much formalisation at a level you can't formalize these kind of problems. MDE and MDD are still trying to prove themselves and in my mind show great promise. e.g. look at MetaEdit The detail still needs to be management in my mind, but you do so in one place (framework or generators) instead of at multiple places. Right for our kind of problems ? I think depends on what problems you look at. Do the current programming languages keep up with the current demands on time to market ? Are they good at bridging the business IT communication gap ? So what do you think ?

• Slide-decks from recent Adelaide SQL Server UG meetings

  - by Rob Farley

  The UK has been well represented this summer at the Adelaide SQL Server User Group, with presentations from Chris Testa-O’Neill (isn’t that the right link? Maybe try this one) and Martin Cairney. The slides are available here and here. I thought I’d particularly mention Martin’s, and how it’s relevant to this month’s T-SQL Tuesday. Martin spoke about Policy-Based Management and the Enterprise Policy Management Framework – something which is remarkably under-used, and yet which can really impact your ability to look after environments. If you have policies set up, then you can easily test each of your SQL instances to see if they are still satisfying a set of policies as defined. Automation (the topic of this month’s T-SQL Tuesday) should mean that your life is made easier, thereby enabling to you to do more. It shouldn’t remove the human element, but should remove (most of) the human errors. People still need to manage the situation, and work out what needs to be done, etc. We haven’t reached a point where computers can replace people, but they are very good at replace the mundaneness and monotony of our jobs. They’ve made our lives more interesting (although many would rightly argue that they have also made our lives more complex) by letting us focus on the stuff that changes. Martin named his talk Put Your Feet Up, which nicely expresses the fact that managing systems shouldn’t be about running around checking things all the time. It must be about having systems in place which tell you when things aren’t going well. It’s never quite as simple as being able to actually put your feet up, but certainly no system should require constant attention. It’s definitely a policy we at LobsterPot adhere to, whether it’s an alert to let us know that an ETL package has run successfully, or a script that generates some code for a report. If things can be automated, it reduces the chance of error, reduces the repetitive nature of work, and in general, keeps both consultants and clients much happier.

  - by Martin Hinshelwood

  I will be presenting a session on “Scrum for TFS2010” not once, but twice! If you are going to be at the Aberdeen Partner Group meeting on 27th April, or DDD Scotland on 8th May then you may be able to catch my session. Credit: I want to give special thanks to Aaron Bjork from Microsoft who provided me with most of my material He is a Scrum and Power Point genius. Scrum for Team Foundation Server 2010 Synopsis Visual Studio ALM (formerly Visual Studio Team System (VSTS)) and Team Foundation Server (TFS) are the cornerstones of development on the Microsoft .NET platform. These are the best tools for a team to have successful projects and for the developers to have a focused and smooth software development process. For TFS 2010 Microsoft is heavily investing in Scrum and has already started moving some teams across to using it. Martin will not be going in depth with Scrum but you can find out more about Scrum by reading the Scrum Guide and you can even asses your Scrum knowledge by having a go at the Scrum Open Assessment. Come and see Martin Hinshelwood, Visual Studio ALM MVP and Solution Architect from SSW show you: How to successfully gather requirements with User stories How to plan a project using TFS 2010 and Scrum How to work with a product backlog in TFS 2010 The right way to plan a sprint with TFS 2010 Tracking your progress The right way to use work items What you can use from the built in reporting as well as the Project portals available on from the SharePoint dashboard The important reports to give your Product Owner / Project Manager Walk away knowing how to see the project health and progress. Visual Studio ALM is designed to help address many of these traditional problems faced by teams. It does so by providing a set of integrated tools to help teams improve their software development activities and to help managers better support the software development processes. During this session we will cover the lifecycle of creating work items and how this fits into Scrum using Visual Studio ALM and Team Foundation Server.

• Exchange ActiveSync with multiple email addresses

  - by Martin Robins

  I have Exchange 2007 SP2, and I have successfully connected my Windows Mobile phone via Exchange ActiveSync and can send and receive emails. I have two addresses within my Exchange mailbox, [email protected] and [email protected], with the second being set as the reply address. When I view my email addresses on my device, I see both of these email addresses, however when I send new messages it always selects the first email address as the reply address and not the second. It is probably worth pointing out that, like in the example provided above, the email addresses are shown alphabetically and the address being selected is the first alphabetically (just in case that matters). I would like to set the device to always select the reply address specified in the mailbox, or at least be able to ensure that the address I want is selected if I have to select it manually on the device, but cannot find any way to make this happen. Can anybody help?

• Why the “Toilet” Analogy for SQL might be bad

  - by Jonathan Kehayias

  Robert Davis(blog/twitter) recently blogged The Toilet Analogy … or Why I Never Recommend Increasing Worker Threads , in which he uses an analogy for why increasing the value for the ‘max worker threads’ sp_configure option can be bad inside of SQL Server.  While I can’t make an argument against Robert’s assertion that increasing worker threads may not improve performance, I can make an argument against his suggestion that, simply increasing the number of logical processors, for example from...(read more)

• Easy Listening = CRM On Demand Podcasts

  - by Anne

  OK, here's my NEW favorite resource for CRM On Demand info -- podcasts! Specifically, the CRM On Demand Podcast site -- signed, sealed, and delivered with humor and know-how. Yes, I admit, I know the cast of characters. But let's face it, sometimes dealing with software is just soooo dry! Not so when discussed by the two main commentators, Louis Peters and Robert Davidson, whom someone once referred to as CRM On Demand's "Click and Clack." (Thought that was too good not to pass along!) Anyhow, another huge plus about the site is the option to listen OR to read. Out walking my dog or doing the dishes? Just turn up the podcast. Listening to music or watching TV? I'll read Louis's entertaining write-ups to glean great info about CRM On Demand in a very short period of time. So that you get a better understanding of why I like this site so much, here's a sampling of what's discussed: Five Things about Books of Business As Louis Peters put it in his entry, when you see "Five Things" in the title, "you'll know you're going to get some concrete advice that you can put to work right away." Well, Louis and Robert do just that, pointing you in the right direction when using Books of Business to segment data. Moving to Indexed Fields - A Rough Guide (only an article, not a podcast) I've read all about performance and even helped develop material around it. But nowhere have I heard indexed custom fields referred to as "super heroes." Louis and Robert use imaginative language to describe the process for moving your data to indexed fields for optimal performance. Data Access QA from the Forums I think that everyone would admit that data access and visibility is the most difficult topic to understand in CRM On Demand. Following up on their previous podcast on the same topic, Louis and Robert answer a few key questions from the many postings on the Oracle CRM On Demand forums. And I bet that the scenarios match many companies' business requirements...maybe even yours! We Need to Talk About Adoption Another expert, Tim Koehler, joins Louis to talk about how to drive user adoption: aligning product usage with business results, communicating why and how to use the product, getting feedback on usability, and so on. Hope I've made my point -- turn to these podcasts to hear knowledgeable folks discuss CRM On Demand tips and tricks in entertaining ways. One podcast is even called "SaaS Talk"!

• Gateway IP Returns to Zero

  - by Robert Smith

  When you set a static IP under Ubuntu 12.04.1, you must supply the desired machine IP and the gateway IP, all using the Network Manager. When I first entered them and rebooted, everything worked great. On the second boot, however, Firefox could find no Web page. Upon checking, I discovered that the gateway IP had returned to zero. Now, no matter how often I resupply it, it returns to zero immediately after NM "saves" it: that is, appears as zero when redisplayed. The only way I can get to the Internet is to restore DHCP operation. I need to use static IP for access to my home network. Would appreciate any suggestion. --Robert Smith

• How to create an NFS proxy by using kernel server & client?

  - by Martin C. Martin

  I have a file server that exports as NFS. On an Ubuntu machine I mount that, then try to export it as an NFS volume. When I go to export it, I get the message: exportfs: /test/nfs-mount-point does not support NFS export How can I get this to work, or at least get more information as to what the problem is? Exact steps: Unbuntu 12.04 mount -f nfs myfileserver.com:/server-dir /test/nfs-mount-point [Works fine, I can read & write files] /etc/exports contains: /test/nfs-mount-point *(rw,no_subtree_check) sudo /etc/init.d/nfs-kernel-server restart Stopping NFS kernel daemon [ OK ] Unexporting directories for NFS kernel daemon... [ OK ] Exporting directories for NFS kernel daemon... exportfs: /test/nfs-mount-point does not support NFS export [ OK ] Starting NFS kernel daemon [ OK ]

• who has files open on a linux server

  - by Robert

  I have the fairly common task of finding who has files open on our Linux (Ubuntu ) file server in our Windows environment. We use Samba on the network and I use Putty from my workstation to establish a shell window to run bash scripts. I have been using something like this to find what files are open: (this returns a list of process ids with each open file) Robert:$ sudo lsof | grep "/srv/office/some/folder" Then, I follow up with something like this to show who owns the process: (this returns the name of the machine on the network using the IP4 protocol who owns the process) Robert:$ sudo lsof -p 27295 | grep "IPv4" Now I know the windows client who has a file open and can take action from there. As you can tell this is not difficult but time consuming. I would prefer to have a windows application I can run that would just give me what I want. So, I have been thinking about creating some process I can run on Linux that listens on a port and then returns a clean list of all open files with the IP address of the host who has the file open. Then, a small windows client application that can send the request on the port. It seems like this should be a very common need but I can not find anything like this that has been done before. Any suggestions?

• Sharing code in LGPL and proprietary software

  - by Martin

  Hi I'm working on a piece of software that'll be released as a dll under LGPL. The software interfaces with hardware from a small company that has provided me with the needed libraries and some code to use them correctly (not only headers but its all in a separate file). As far as i know, the same code is used in their proprietary software that they don't intend to open source but they'd be fine releasing the piece of code they've given me. Now here's the question: What license could be used on the code I got from the company? I guess using GPL or LGPL would make them violate GPL when using the same code in their other software. Is MIT a good idea? Is it ok to just include a file with MIT license on it in my otherwise LGPL:ed project? Since I'm not the copyright holder, I'd have to ask the company to apply the license obviously but that shouldn't be a problem. Thanks /Martin

• Can I perform a distribution upgrade without rebooting?

  - by Martin Eve

  Hi, I would, ideally, like to run a distribution upgrade that doesn't end in a complete reboot of the machine (owing to an irritation in my hardware that requires a period of disconnection from the power supply before my SSD can be detected). What would be the procedure for doing this from a desktop environment? I would image: dist-upgrade shutdown all graphical services restart X I'd appreciate any advice (particularly on the exact procedure for step 2, if this correct). NB. I'm using KSplice for in-memory kernel patching, so the kernel is already dealt with. Many thanks, Martin

• Open source engagement as a professional reference

  - by Martin

  if one commits his or her time to an open source project, he or she may be invest a substantial amount of time without getting paid. As much as altruism is appreciable, I wonder whether it "counts" as an activity which can be shown and is valued in job applications. If the company is worth your time and working power, which it should be in my honest opinion. So I wonder whether there is something like a common practice in open source projects for this matters. Say, something like Mr. Martin has been working on our project for five years and has contributed this and that,[...] I we wish him very best for his future. Mr. ChiefofProject I think this is a just concern. Do have experiences you can share?

• How do I prove or disprove "god" objects are wrong?

  - by honestduane

  Problem Summary: Long story short, I inherited a code base and an development team I am not allowed to replace and the use of God Objects is a big issue. Going forward, I want to have us re-factor things but I am getting push-back from the teams who want to do everything with God Objects "because its easier" and this means I would not be allowed to re-factor. I pushed back citing my years of dev experience, that I'm the new boss who was hired to know these things, etc, and so did the third party offshore companies account sales rep, and this is now at the executive level and my meeting is tomorrow and I want to go in with a lot of technical ammo to advocate best practices because I feel it will be cheaper in the long run (And I personally feel that is what the third party is worried about) for the company. My issue is from a technical level, I know its good long term but I'm having trouble with the ultra short term and 6 months term, and while its something I "know" I cant prove it with references and cited resources outside of one person (Robert C. Martin, aka Uncle Bob), as that is what I am being asked to do as I have been told having data from one person and only one person (Robert C Martin) is not good enough of an argument. Question: What are some resources I can cite directly (Title, year published, page number, quote) by well known experts in the field that explicitly say this use of "God" Objects/Classes/Systems is bad (or good, since we are looking for the most technically valid solution)? Research I have already done: I have a number of books here and I have searched their indexes for the use of the words "god object" and "god class". I found that oddly its almost never used and the copy of the GoF book I have for example, never uses it (At least according to the index in front of me) but I have found it in 2 books per the below, but I want more I can use. I checked the Wikipedia page for "God Object" and its currently a stub with little reference links so although I personally agree with that it says, It doesn't have much I can use in an environment where personal experience is not considered valid. The book cited is also considered too old to be valid by the people I am debating these technical points with as the argument they are making is that "it was once thought to be bad but nobody could prove it, and now modern software says "god" objects are good to use". I personally believe that this statement is incorrect, but I want to prove the truth, whatever it is. In Robert C Martin's "Agile Principles, Patterns, and Practices in C#" (ISBN: 0-13-185725-8, hardcover) where on page 266 it states "Everybody knows that god classes are a bad idea. We don't want to concentrate all the intelligence of a system into a single object or a single function. One of the goals of OOD is the partitioning and distribution of behavior into many classes and many function." -- And then goes on to say sometimes its better to use God Classes anyway sometimes (Citing micro-controllers as an example). In Robert C Martin's "Clean Code: A Handbook of Agile Software Craftsmanship" page 136 (And only this page) talks about the "God class" and calls it out as a prime example of a violation of the "classes should be small" rule he uses to promote the Single Responsibility Principle" starting on on page 138. The problem I have is all my references and citations come from the same person (Robert C. Martin), and am from the same single person/source. I am being told that because he is just one guy, my desire to not use "God Classes" is invalid and not accepted as a standard best practice in the software industry. Is this true? Am I doing things wrong from a technical perspective by trying to keep to the teaching of Uncle Bob? God Objects and Object Oriented Programming and Design: The more I think of this the more I think this is more something you learn when you study OOP and its never explicitly called out; Its implicit to good design is my thinking (Feel free to correct me, please, as I want to learn), The problem is I "know" this, but but not everybody does, so in this case its not considered a valid argument because I am effectively calling it out as universal truth when in fact most people are statistically ignorant of it since statistically most people are not programmers. Conclusion: I am at a loss on what to search for to get the best additional results to cite, since they are making a technical claim and I want to know the truth and be able to prove it with citations like a real engineer/scientist, even if I am biased against god objects due to my personal experience with code that used them. Any assistance or citations would be deeply appreciated.

• Expando Object and dynamic property pattern

  - by Al.Net

  I have read about 'dynamic property pattern' of Martin Fowler in his site under the tag 1997 in which he used dictionary kind of stuff to achieve this pattern. And I have come across about Expando object in c# very recently. When I see its implementation, I am able to see IDictionary implemented. So Expando object uses dictionary to store dynamic properties and is it what, Martin Fowler already defined 15 years ago?

• Troubleshooting Your Network with Oracle Linux

  - by rickramsey

  Are you afraid of network problems? I was. Whenever somebody said "it's probably the network," I went to lunch. And hoped that it was fixed by the time I got back. Turns out it wasn't that hard to do a little basic troubleshooting Tech Article: Troubleshooting Your Network with Oracle Linux by Robert Chase You're no doubt already familiar with ping. Even I knew how to use ping. Turns out there's another command that can show you not just whether a system can respond over the network, but the path the packets to that system take. Our blogging platform won't allow me to write the name down, but I can tell you that if you replace the x in this word with an e, you'll have the right command: tracxroute Once you get used to those, you can venture into the realms of mtr, nmap, and netcap.

• Adventures in Scrum: Lesson 2 - For the record

  - by Martin Hinshelwood

  At SSW we have always done Agile. Recently we have started doing Scrum and we have nearly completed our first Sprint ever using Scrum. As you probably guessed from my previous post, it looks like it is going to be a “Failed Sprint”, but the Scrum Team (This includes the ScrumMaster and the Product Owner) has learned a huge amount about working in the Scrum Framework. We have been running with a “Proxy Product Owner” for the last two weeks, but a simple mistake occurred either during the “Product Planning Meeting” or the “Sprint Planning Meeting” that could have prevented this Sprint from failing. We has a heated discussion on the vision of someone not in the room which ended with the assertion that the Product Owner would be quizzed again on their vision. This did not happen and we ran with the “Proxy Product Owner’s vision for two weeks. Product Owner vision: Update Component A of Product A to Silverlight Proxy Product Owner vision: Update Product A to Silverlight Do you see the problem? Worse than that, as we had a lot of junior members of the Scrum Team and we are just feeling our way around how Scrum will work at SSW I missed implementing a fundamental rule. That’s right, it was me. It does not matter that I did not know about this rule, its on the site and I should have read it. Would a police officer let you off if you did not know that a red light meant stop? I think not… But, what is this amazing rule I hear you shout.. Its simple, as per our rule I should have sent the following email: “ Dear Proxy Product Owner, For the record, I disagree that the Product Owner wants us to ‘Update Product A to Silverlight’ as I still think that he wants us to ‘Update Component A of Product A to Silverlight’ and not the entire application. Regards Martin” - ‘For the record’ - Rules to being Software Consultants - Dealing with Clients This email should have been copied to the entire Scrum Team, which would have included the Product Owner, who would have nipped this misunderstanding in the bud and we would have had one less impediment.

• Ubuntu eats itself after I followed updater instruction

  - by Tony Martin

  Updater (I assume) put a no entry style alert icon on the panel which informed me that certain package dependencies were not up to snuff. Upgrades were thereafter only partial. The dialogue advised that I (and this is from noob memory) sudo apt-get install -f. I did this and typed in the confirmation phrase and watched apt-get systematically remove every component of linux, both the stuff I installed and the core ubuntu packages. I could only assume at this stage that this was for a fresh install but of course, I know better now. There's much complaint about Windows, but I've never met with advice from Microsoft tools to wipe out the operating system because of a couple of missing .dlls. So what gives? This was a 64 bit install of 12.04. All that is left is grub pointing to a couple of windows recovery partitions on the hard drive. I'm tempted, but I have hopes of recovering the data that I had enough misguided faith to trust to the linux ext4 partition. I've tried pen driving back into it with a 32 bit iso but I'm simply informed that ubuntu is running in low graphics mode and get to watch the dots cycle indefinitely. EDIT: Thanks for the advice vis positive request. I've got onto the machine with a 64 bit stick and can see the file structure left behind by the installation. My first instinct was to run install from the stick but it did not seem to offer a recovery option. My question then: is there a way to recover the current installation so that if I reinstall the packages I had they will pick up the original settings. I'm particularly worried about losing email from evolution - the rest I could probably lash back together. I would also be interested how this disaster came about. I see people in the know recommending this same procedure in similar circumstances. Thanks for your attention, Tony Martin

• LinkedIn Woopsie with the Outlook 2010 Social Media Connector

  - by Martin Hinshelwood

  I have always used the LinkedIn toolbar for Outlook to sort out, upload and sync my contacts. Because of this I have over 2000 contacts in my contacts list that I sync with my phone, Plaxo, live, Google and others. I got a surprise the other day when my LinkedIn account was suspended and I was unable to login.   Figure: Bad, account suspended   So I contacted LinkedIn customer services to find out what the problem is, and here is the response: Dear Martin, We have recently noticed a large number of page searches and profile views through your LinkedIn account. We are aware that you may be using an automated or manual process to systematically view LinkedIn web pages. The information within LinkedIn is provided by our users for usage on the site only. In order to protect user privacy, our User Agreement prohibits using: 1. Automated or manual means to view an excessively high number of profiles or mini-profiles. 2. Automated means to run searches to collect or store data obtained from our site. We have placed a restriction on your account until you agree to stop using these or similar methods to view pages on LinkedIn. We look forward to your reply to discuss this further. Sincerely, LinkedIn Privacy Team It looks like LinkedIn has suspended my account because of something that their component is doing! I do not know if this is an isolated case, or if it will happen more as more users get on Outlook 2010 and update to the new software, but watch out. Has anyone else been suspended who has installed the Office 2010 RTM and the LinkedIn Add-On? Technorati Tags: Fail,LinkedIn,Outlook 2010

• Disassembler that tracks what value is where

  - by Martin C. Martin

  So lately I've been looking at the disassembly of my C++ code, and having to manually track what's in each register, like this: 95: 48 8b 16 mov (%rsi),%rdx ; %rdx = raggedCross.sink 98: 48 8b 42 38 mov 0x38(%rdx),%rax ; %rax = sink.table 9c: 8b 4a 10 mov 0x10(%rdx),%ecx ; %ecx = sink.baseCol 9f: 48 8b 70 50 mov 0x50(%rax),%rsi ; %rsi = table.starts a3: 89 c8 mov %ecx,%eax ; %eax = baseCol a5: 83 c1 1c add $0x1c,%ecx ; %ecx = baseCol + 1 And so on. The comments are mine, added by hand, from looking up the offset of various fields (e.g. sink, table, baseCol, starts) in the C++ classes. It's straight forward to do, but tedius and time consuming: the perfect thing for a program to be doing. gdb seems to know the offset of various fields within a struct: I can do &((Table *)0x1200)-starts and it tells the the right address. So, this information is around. Is there some disassembler that can use this info to annotate the code for me? Failing that, I could write my own. Where does gdb get the offsets?
