• Help, broken Gsettings

  - by Rene

  I was trying to disable the global menu as per http://ubuntuhandbook.org/index.php/2013/07/disable-global-menu-on-ubuntu-13-10-saucy/#comment-8612, but while it didn't change anything, after running the autoremove command unity-tweak-tool broke. Obviously my first reaction was to re-install the removed package but it remains broken. TBH I don't know if it is even related or just a coincidence. When I start it from the launcher it just blinks and disappear. When I start it from terminal I get this error: $ gnome-tweak-tool WARNING : Shell not installed or running WARNING : Error detecting shell Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/gtweak/tweaks/tweak_shell_extensions.py", line 199, in __init__ raise Exception("Shell not running or DBus service not available") Exception: Shell not running or DBus service not available INFO : GSettings missing key org.gnome.nautilus.desktop (key computer-icon-visible) WARNING : Shell not running None INFO : GSettings missing key org.gnome.mutter (key workspaces-only-on-primary) Segmentation fault (core dumped) I had a look with dconf-editor if I could just add the missing key, but apparently keys aren't meant to be added "by hand". So how can I fix this? I'd rather prefer not having to reinstall everything. Which package is broken, can I just reinstall that? EDIT: I found by being root gnome-tweak-tool no longer crashed so possibly a permission issue somewhere. I don't know that I changed any permissions. Another related problem, actually the reason I noticed the problem at all, is that unity-tweak-tool seem no longer to want to save the values edited. I normally just have the Unity launcher on the primary display but wanted to check what it was like having it on both. I didn't like it so I went into unity-tweak-tool to set it back - but regardless how many time I tick "only primary display" it never changes anything. What does the Unity-tweak-tool actually change and can I do this directly somehow?

  Andy Mulholland: Rethinking the narrow and deep expertise model "We increasingly realise that we have to read requirements in a more open way to decide what techniques can be used, what business experience can be added, etc, so the whole idea of encouraging ‘cross’ discipline understanding seems to look increasingly necessary as we look at how technology touches every part of business, and/or any other aspect of life. It is time to rethink the narrow and deep expertise model and consider T-shaped approaches where the depth is complimented by the width to understand how it might be used and how it fits with other capabilities and disciplines too." -- Andy Mulholland (tags: enterprisearchitecture) @vambenepe: Smoothing a discrete world "For the short term (until we sell one) there are three cars in my household.

• Thinktecture.IdentityServer Beta 1

  - by Your DisplayName here!

  I just upload beta 1 to codeplex. Please test this version and give me feedback. Some quick notes on setup Watch the intro screencast on the codeplex site. Use the setup tool to set the signing and SSL certificate. You can now also set the ACLs on the private key for your worker pool account. IIS is required . SSL for the IIS site the STS runs in is required. Users of the STS must be in the 'IdentityServerUsers' role. Admins of the STS must be in the 'IdentityServerAdministrators' roles. What’s new? Mainly smaller bits and pieces and some refactoring. The biggest under the cover change is a new authorization model for the STS itself. If, e.g. you don’t like the new roles I introduced, you can easily change the behavior in the claims authorization manager in the STS web site project. What’s missing? The big one is Azure support. Not that I ran into unforeseeable problems here, I just wanted to wait until the on-premise version is more stabilized. Now with B1 I can start adding Azure support back.

• Inevitable Corporate Bureaucracy

  - by Ahsan Alam

  Top executives of most smaller organizations want their companies to be different from the larger corporations. They want their organizations smaller in size; but bigger in productivity by eliminating red tapes and corporate bureaucracy. When the company is smaller, people often work like firefighters – taking on new business and technology challenges without thinking about any procedures and guidelines. People also tend to wear many hats to accomplish tasks quickly in order to integrate new businesses. For example, software developers in smaller organizations may take on responsibilities of client interactions, requirements gathering, design and development, code deployment, production support, network infrastructure support, database design and maintenance along with countless other duties. In addition, systems in smaller organizations tend to be loosely guarded. So, people often don't follow many procedures in order to setup environments and implement technical projects. It's not uncommon to change code and deploy without anyone realizing. Similarly, business requirements may also get defined in an informal manner without any type of documentation. As the company grows, everything starts to change significantly impacting people and the overall business process. Suddenly, following procedures become extremely important. Consequently, new roles, guidelines and procedures start to emerge. Everything from business process to technology implementation start to become more and more process oriented. Organizations start to define and document steps, invent procedure to track process and systems level changes, and start restricting access to various systems for security reasons. At the same time, as a growing company start doing businesses with larger clienteles, they are automatically forced to abide by all sorts of industry compliance laws. Moreover, growing companies tend to recruit experienced individuals to fill new roles who usually bring their expertise from larger and more bureaucratic organizations.   Despite the best efforts from the top executives, it seems increased number of procedures and guidelines as well as new recruits automatically contribute to the evolution of corporate bureaucracy. Maybe, corporate bureaucracy is an inevitable side effect of a growing organization.

• Not Happy With the Monochrome Visual Studio 11 Beta UI

  - by Ken Cox [MVP]

  I can’t wait for a third-party to come out with tools to return some colour to the flat, monochrome look of Visual Studio 11 (beta). What bugs me most are the icons. I feel like a newbie when I have to squint and analyze the shape of icons on the debugging toolbar just to get the one I want. (Fortunately, the meddlers didn’t mess with the keyboard commands so I’m not totally lost.) Not sure what usability studies told MS that bland is better. Maybe it is for most people, but not for me.  Gray, shades of gray and black. Ugh. And don’t get me started on the stupidity of using all-caps for window titles. Who approved that? I see that there’s a UserVoice poll on the topic (http://visualstudio.uservoice.com/forums/121579-visual-studio/suggestions/2623017-add-some-color-to-visual-studio-11-beta) but I doubt that anything will change Microsoft’s opinion in time for the release. Once a product gets to a stable beta, most non-crashing stuff gets pushed to the next version. I hope I’m proved wrong. Fortunately, Visual Studio is quite customizable. Unless ‘Bland’ is hard-coded, some registry tweaks and a collection of replacement icons should allow dissenters like me back to productivity. BTW, other than hating the UI, VS 11 beta is working quite well for me on a .NET 4 project.Note: Although my username for the ASP.NET domain includes the letters "[MVP]", I'm no longer an MVP. Apparently it's nearly impossible to change a username in the system. My apologies for the misleading identifier but I tried to have it changed without success.

• Bridging the gap between developers and testers with VS 2010

  - by Etienne Tremblay

  Hey everyone, I know it’s been an eternity since I blogged but I have so much to do that I unfortunately need to prioritize.  Vincent Grondin and I did a 7h presentation on the new developer and tester tools available in the VS 2010 suite.  It was a blast.  We did it in front of an audience (around 120) and it was taped.  We did it as a play and really didn’t look at the crowd at all we were training each other on the technology. It is now available for anyone that would like to watch it at this location: http://www.devteach.com/ALM-TFS2010-Bridgingthegap.aspx What we covered in the full day event was Migration to TFS 2010 (10h00) 1-Migration of VSS to TFS (20 min.) 2-Automating the Build (Something you can't do with VSS) ( 20 Min.) 3-User story (Real application context for this presentation) (20 min.) 10h00 Pause Manuel Tests by Dev ( 11h30) 4-Adding a tester to the team (Into to MTM) (20 min.) 5-Define tests (what is a white bug) (20 min.) 6-Fix the bug and show Intellitrace and Play back the test (20 min.) 12h15 Lunch Manuel testing for maintenance (13h30) 7- Implement new Feature (web service) and Identify bug with MTM and branch for a production fix and also add a new Build script (20 min.) 8- Fix bug in production branch, Playback tests, merge the change in main branch (20 min.)

• What would you do to improve the working of a small Development team?

  - by Omar Kooheji

  My company is having a reshuffle and I'm applying for my boss' job as he's moved up the ladder. The new role would give me a chance to move our development team into the 21st century and I'd like to make sure that: I can provide sensible suggestions in the interview to get the job so I can fix the team If I get the job I can actually enact some changes to actually improve the lives of the developers and their output. I want to know what I can suggest to improve the way we work, because I think it's a mess but every time I've suggested a change it's been shot down because any time spend implementing the change would be time that isn't spent developing software. Here is the state of play at the moment: My team consists of 3-4 developers (Mainly Java but I do some .Net work) Each member of the team is usually works on 2-3 projects at a time We are each responsible for the entire life cycle of the project from design to testing. Usually only one person works on a project (Although we have the odd project that will have more than one person working on it.) Projects tend to be bespoke to single customer, or are really heavilly reliant on a particular customer environment. We have 2-3 "Products" which we evolve to meet customer requirements. We use SVN for source control We don't do continuous integration (I'd like to start) We use a really basic bug tracker for internal issue tracking (I'd like to move to an issue/task management system) Any changes that bring a sudden dip in revenue generation will probably be rejected, the company isn't structured for development most of the rest of the technical team's jobs can be broken down to install this piece of hardware, configure that piece of hardware and once a job is done it's done and you never have to look at it again. This mentality has crept into development team because it's part of the company culture.

• Huge google impression drop after cleaning html

  - by olgatorresfoundation

  Good morning, I am the webmaster of a non-profit organization that donates grants to colorectal cancer research projects and funds various colorectal cancer information campaigns. We have three domains: www.fundacioolgatorres dot org (Catalan) www.fundacionolgatorres dot org (Spanish) www.olgatorresfoundation dot org (English) So what happened? I redesigned olgatorresfoundation on the 20th and the fundacionolgatorres on the 30th of May. In both cases, exactly two days later, the number of impressions on both dropped to a halt. Granted, we did not have the traffic of Microsoft, but a 90% decrease a disaster of incredible proportions for us. My only real changes were cleaning up the old ineffective HTML to a cleaner form (mostly moving away from redundant table construction to a table-less view). Here is a before and after snapshot of what the change looks like: Before: http://www.fundacioolgatorres.org/aparell_digestiu/introduccio/ (unchanged page in Catalan) After: http://www.olgatorresfoundation.org/digestive_system/introduction/ (changed page in English) Anybody has a clue to what just happened? Why should a normal, sane html improvement be punished and so dramatically? No URLs have been changed, neither have page names or descriptions. Possible secondary question: If it is so that Google sees it as a major overhaul and decides to drop the pagerank sharply, does it come back to pre-change levels if the content "checks out" or will the page start over from scratch earning those pagerank points (which would mean that we would have to wait 6 months for the pages to recover to the level they had two weeks ago)? (duplicated from productforums.google dot com/forum/#!category-topic/webmasters/crawling-indexing--ranking/YsnyX0JzOpY, hoping to reach a wider audience)

• Identity in .NET 4.5&ndash;Part 1: Status Quo (Beta 1)

  - by Your DisplayName here!

  .NET 4.5 is a big release for claims-based identity. WIF becomes part of the base class library and structural classes like Claim, ClaimsPrincipal and ClaimsIdentity even go straight into mscorlib. You will be able to access all WIF functionality now from prominent namespaces like ‘System.Security.Claims’ and ‘System.IdentityModel’ (yay!). But it is more than simply merging assemblies; in fact claims are now a first class citizen in the whole .NET Framework. All built-in identity classes, like FormsIdentity for ASP.NET and WindowsIdentity now derive from ClaimsIdentity. Likewise all built-in principal classes like GenericPrincipal and WindowsPrincipal derive from ClaimsPrincipal. In other words, the moment you compile your .NET application against 4.5,  you are claims-based. That’s a big (and excellent) change.   While the classes are designed in a way that you won’t “feel” a difference by default, having the power of claims under the hood (and by default) will change the way how to design security features with the new .NET framework. I am currently doing a number of proof of concepts and will write about that in the future. There are a number of nice “little” features, like FindAll(), FindFirst(), HasClaim() methods on both ClaimsIdentity and ClaimsPrincipal. This makes querying claims much more streamlined. I also had to smile when I saw ClaimsPrincipal.Current (have a look at the code yourself) ;) With all the goodness also comes a number of breaking changes. I will write about that, too. In addition Vittorio announced just today the beta availability of a new wizard/configuration tool that makes it easier to do common things like federating with an IdP or creating a test STS. Go get the Beta and the tools and start writing claims-enabled applications! Interesting times ahead!

• Unable to access ubuntu through windows boot manager

  - by Arvind

  I am having an ASUS K55VM....it came with DOS....to this Windows 7 was installed...now i am planned to add another OS ie Ubuntu...my computer had 4 partitions of 240GB 230GB 230GB and 230GB....i changed this to 5 parts....243GB 230GB 230GB 150GB and an 80GB...i installed Ubuntu 12.04 to the 80GB partition through a USB flash drive....it installed fine...however the problem is during the Boot option in Windows Boot manager when i choose Ubuntu...this what is displayed... Windows failed to start. A recent hardware or software change might be the cause. To fix the problem: 1.Insert your Windows installation disc and restart your computer. 2.Choose your language settings, and then click "Next." 3.Click "Repair your computer." If you do not have this disc, contact your system administrator or computer manufacturer for assistance. File: \ubuntu\winboot\wubildr.mbr Status: 0xc000000e Info: The selected entry could not be loaded because the application is missing or corrupt. I tried to change the boot option for the OS and made Ubuntu as my first option....It worked...however windows 7 does not show up in GRUB....in this fear i did the following: Restarted my pc changed boot option 1 to windows. Formatted the drive to which Ubuntu was installed(80GB one)through windows. Restarted again. The problem persists....Windows boot manager shows Ubuntu still and when i choose this it gives two lines one like: grub rescue....but my windows 7 is working perfectly fine. Now want a solution to remove Ubuntu from the windows boot option and reinstall completely...

• Highly scalable and dynamic "rule-based" applications?

  - by Prof Plum

  For a large enterprise app, everyone knows that being able to adjust to change is one of the most important aspects of design. I use a rule-based approach a lot of the time to deal with changing business logic, with each rule being stored in a DB. This allows for easy changes to be made without diving into nasty details. Now since C# cannot Eval("foo(bar);") this is accomplished by using formatted strings stored in rows that are then processed in JavaScript at runtime. This works fine, however, it is less than elegant, and would not be the most enjoyable for anyone else to pick up on once it becomes legacy. Is there a more elegant solution to this? When you get into thousands of rules that change fairly frequently it becomes a real bear, but this cannot be that uncommon of a problem that someone has not thought of a better way to do this. Any suggestions? Is this current method defensible? What are the alternatives? Edit: Just to clarify, this is a large enterprise app, so no matter which solution works, there will be plenty of people constantly maintaining its rules and data (around 10). Also, The data changes frequently enough to say that some sort of centralized server system is basically a must.

• 5 Ways Microsoft Can Improve the Windows 8 Start Screen

  - by Matt Klein

  After having used Windows 8 over the past few months, we’ve found a few ways Microsoft could immediately improve the Start Screen to make it less disorienting and more usable, not only for tablets but desktops and laptops as well. It’s safe to say that the one thing Windows 8 doesn’t lack is criticism. Since the Consumer Preview debuted in February, it has proven to be one of the most polarizing Windows releases ever. But regardless of whether you love or hate it, Windows 8 is where Microsoft’s venerable operating system is headed. Portable computing is here to stay and if the company is to survive, let alone remain relevant, it has to change, adapt, embrace, and extend. Perhaps the single most universally controversial change to Windows is Microsoft’s decision to remove the Start button (or orb, if you’ve moved beyond XP) and with it, what we know to be the Start Menu. In their place we now have a Start hot corner (a workable alternative) and the newly redesigned Metro Start Screen. The Start Screen is, if nothing else, different. Beyond a doubt, there has not been such a radical redesign of Windows’ Start functionality since it went to a two-column design with a nested “All Programs” menu in Windows XP. The Start Screen can be a little jarring because it requires users to not only relearn what they’ve known for nearly two decades but to also rethink the way they interact with Windows. However, the Start Screen maintains its core elements: a Start “menu”, a place for all installed programs (All apps), and a search pane. The Start Screen is attractive, clean, bold, and very imperfect. Here are five changes we’d like to see in the Start Screen before Windows 8 goes gold … How to Make Your Laptop Choose a Wired Connection Instead of Wireless HTG Explains: What Is Two-Factor Authentication and Should I Be Using It?

• WordPress page title repeated in SOME pages

  - by cmykrgbb

  I have created a Wordpress site and titles were working just fine. Then, some time and plugins installed later, I noticed that in SOME pages I get the title repeated 2 times. Example of wrong page title: Contact - NAME | NAME Example of normal title: Our Services | NAME Now, if I go to General Settings and change title it will change both, no improvement. SEO by Yoast has the option to reset page titles, but that just removes all titles leaving the current URL as page title, so no good either. Here is the code I originally had: <title><?php wp_title(''); ?><?php if(wp_title('', false)) { echo ' | '; } ?><?php bloginfo('name'); ?></title> Here is the code I am using now: <title><?php wp_title('|'); ?></title> To sum up, I think somewhere in the database there's a wp_title repeated: once using '-' as separator, another one (the current one) using '|'. Any help will be most appreciated, thanks!

• Some Nice Icon Themes for Ubuntu [on hold]

  - by Saurav Kumar

  Last night I was searching for some good looking icon themes availabe for Ubuntu, but unfortunately could not find any post which gives a list of themes :(. From yesterday night I started searching icons themes and installing one by one. So thought to share some of them hope it will help others to get a bunch of them in one post. This is a Q&A-Style tutorial which will cover: Few good icon themes which are used in famous Ubuntu type distros and are available in repository. Look and feel through pictures. How to easily install? I also request others to share their experiences of some awesome icon themes. Once themes are installed Ubuntu-Tweak will help to change and manage them, since I could not find another way to change the themes in Unity. In xfce(Xubuntu) it can be changed from Appearance. Just believe me this post will not be vast. If I'll remove pictures then it will become small, but it will not look good. Please give suggestion to make it small.

• What are the packages/libraries I should install before compiling Python from source?

  - by Lennart Regebro

  Once in a while I need to install a new Ubuntu (I used it both for desktop and servers) and I always forget a couple of libraries I should have installed before compiling, meaning I have to recompile, and it's getting annoying. So now I want to make a complete list of all library packages to install before compiling Python (and preferably how optional they are). This is the list I compiled with below help and by digging in setup.py. It is complete for Ubuntu 10.04 and 11.04 at least: build-essential (obviously) libz-dev (also pretty common and essential) libreadline-dev (or the Python prompt is crap) libncursesw5-dev libssl-dev libgdbm-dev libsqlite3-dev libbz2-dev More optional: tk-dev libdb-dev Ubuntu has no packages for v1.8.5 of the Berkeley database, nor (for obvious reasons) the Sun audio hardware, so the bsddb185 and sunaudiodev modules will still not be built on Ubuntu, but all other modules are built with the above packages installed. Python 2.5 and Python 2.6 also needs to have LDFLAGS set on Ubuntu 11.04 and later, to handle the new multi-arch layout: export LDFLAGS="-L/usr/lib/$(dpkg-architecture -qDEB_HOST_MULTIARCH)" For Python 2.6 and 2.7 you also need to explicitly enable SSL after running the ./configure script and before running make. In Modules/Setup there are lines like this: #SSL=/usr/local/ssl #_ssl _ssl.c \ # -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \ # -L$(SSL)/lib -lssl -lcrypto Uncomment these lines and change the SSL variable to /usr: SSL=/usr _ssl _ssl.c \ -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \ -L$(SSL)/lib -lssl -lcrypto Python 2.6 also needs Modules/_ssl.c modified to be used with OpenSSL 1.0, which is used in Ubuntu 11.10. At around line 300 you'll find this: else if (proto_version == PY_SSL_VERSION_SSL3) self->ctx = SSL_CTX_new(SSLv3_method()); /* Set up context */ else if (proto_version == PY_SSL_VERSION_SSL2) self->ctx = SSL_CTX_new(SSLv2_method()); /* Set up context */ else if (proto_version == PY_SSL_VERSION_SSL23) self->ctx = SSL_CTX_new(SSLv23_method()); /* Set up context */ Change that into: else if (proto_version == PY_SSL_VERSION_SSL3) self->ctx = SSL_CTX_new(SSLv3_method()); /* Set up context */ #ifndef OPENSSL_NO_SSL2 else if (proto_version == PY_SSL_VERSION_SSL2) self->ctx = SSL_CTX_new(SSLv2_method()); /* Set up context */ #endif else if (proto_version == PY_SSL_VERSION_SSL23) self->ctx = SSL_CTX_new(SSLv23_method()); /* Set up context */ This disables SSL_v2 support, which apparently is gone in OpenSSL1.0.

• WebLogic Application Server: free for developers! by Bruno Borges

  - by JuergenKress

  Great news! Oracle WebLogic Server is now free for developers! What does this mean for you? That you as a developer are permitted to: "[...] deploy the programs only on your single developer desktop computer (of any type, including physical, virtual or remote virtual), to be used and accessed by only (1) named developer." But the most interesting part of the license change is this one: "You may continue to develop, test, prototype and demonstrate your application with the programs under this license after you have deployed the application for any internal data processing, commercial or production purposes" (Read the full license agreement here).

• Colour coding of the status bar in SQL Server Management Studio - Oh dear

  - by simonsabin

  The new feature in SQL Server 2008 to have your query window status bar colour coded to the server you are on is great. Its a nice way to distinguish production from development servers. Unfortunately it was pointed out to me by a client recently that it doesn't always work. To me that sort of makes it pointless. Its a bit like having breaks that work some of the time. Are you going to place Russian roulette every time you execute the query. Whats more the colour doesn't change if you change the connection. So you can flip between dev and production servers but your status bar stays the colour you set for the dev server. It really annoys me to find features that sort of work. The reason I initially gave up on SQLPrompt was that it didn't work 100% of the time and for that time it didn't work I wasted so much time trying to get it to work I wasted more time than if I didn't have it. (I will say that was 2-3 years ago). If you would like to use this feature but aren't because of these features please vote on these bugs. https://connect.microsoft.com/SQLServer/feedback/details/504418/ssms-make-color-coding-of-query-windows-work-all-the-time https://connect.microsoft.com/SQLServer/feedback/details/361832/update-status-bar-colour-when-changing-connections

• Should one always know what an API is doing just by looking at the code?

  - by markmnl

  Recently I have been developing my own API and with that invested interest in API design I have been keenly interested how I can improve my API design. One aspect that has come up a couple times is (not by users of my API but in my observing discussion about the topic): one should know just by looking at the code calling the API what it is doing. For example see this discussion on GitHub for the discourse repo, it goes something like: foo.update_pinned(true, true); Just by looking at the code (without knowing the parameter names, documentation etc.) one cannot guess what it is going to do - what does the 2nd argument mean? The suggested improvement is to have something like: foo.pin() foo.unpin() foo.pin_globally() And that clears things up (the 2nd arg was whether to pin foo globally, I am guessing), and I agree in this case the later would certainly be an improvement. However I believe there can be instances where methods to set different but logically related state would be better exposed as one method call rather than separate ones, even though you would not know what it is doing just by looking at the code. (So you would have to resort to looking at the parameter names and documentation to find out - which personally I would always do no matter what if I am unfamiliar with an API). For example I expose one method SetVisibility(bool, string, bool) on a FalconPeer and I acknowledge just looking at the line: falconPeer.SetVisibility(true, "aerw3", true); You would have no idea what it is doing. It is setting 3 different values that control the "visibility" of the falconPeer in the logical sense: accept join requests, only with password and reply to discovery requests. Splitting this out into 3 method calls could lead to a user of the API to set one aspect of "visibility" forgetting to set others that I force them to think about by only exposing the one method to set all aspects of "visibility". Furthermore when the user wants to change one aspect they almost always will want to change another aspect and can now do so in one call.

• Is it better to hard code data or find an algorithm?

  - by OghmaOsiris

  I've been working on a boardgame that has a hex grid as the board (the upper right grid in the image below) Since the board will never change and the spaces on the board will always be linked to the same other spaces around it, should I just hard code every space with the values that I need? Or should I use various algorithms to calculate links and traversals? To be more specific, my board game is a 4 player game where each player has a 5x5x5x5x5x5 hex grid (again, the upper right grid in th eimage above). The object is to get from the bottom of the grid to the top, with various obstacles in the way, and each players being able to attack eachother from the edge of their grid onto other players based on a range multiplier. Since the players grid will never change and the distance of any arbitrary space from the edge of the grid will always be the same, should I just hard code this number into each of the spaces, or should I still use a breadth first search algorithm when players are attacking? The only con I can think of for hard coding everything is that I'm going to code 9+ 2(5+6+7+8) = 61 individual cells. Is there anything else that I'm missing that I should consider using more complex algorithms?

• Should we be able to deploy a single package to the SSIS Catalog?

  - by jamiet

  My buddy Sutha Thiru sent me an email recently asking about my opinion on a particular nuance of the project deployment model in SQL Server Integration Services (SSIS) 2012 and I’d like to share my response as I think it warrants a wider discussion. Sutha asked: Jamie What is your take on this? http://www.mattmasson.com/index.php/2012/07/can-i-deploy-a-single-ssis-package-from-my-project-to-the-ssis-catalog/ Overnight I was talking to Matt who confirmed that they got no plans to change the deployment model. For example if we have following scenrio how do we do deploy? Sprint 1 Pkg1, 2 & 3 has been developed and deployed to UAT. Once signed off its been deployed to Live. Sprint 2 Pkg 4 & 5 been developed. During this time users raised a bug on Pkg2. We want to make the change to Pkg2 and deploy that to UAT and eventually to LIVE without releasing Pkg 4 &5. How do we do it? Matt pointed me to his blog entry which I have seen before . http://www.mattmasson.com/index.php/2012/02/thoughts-on-branching-strategies-for-ssis-projects/ Thanks Sutha My response: Personally, even though I've experienced the exact problem you just outlined, I agree with the current approach. I steadfastly believe that there should not be a way for an unscrupulous developer to slide in a new version of a package under the covers. Deploying .ispac files brings a degree of rigour to your operational processes. Yes, that means that we as SSIS developers are going to have to get better at using source control and branching properly but that is no bad thing in my opinion. Claiming to be proper "developers" is a bit of a cheap claim if we don't even do the fundamentals correctly. I would be interested in the thoughts of others who have used the project deployment model. Do you agree with my point of view? @Jamiet

• Should we write detailed architecture design or just an outline when designing a program?

  - by EpsilonVector

  When I'm doing design for a task, I keep fighting this nagging feeling that aside from being a general outline it's going to be more or less ignored in the end. I'll give you an example: I was writing a frontend for a device that has read/write operations. It made perfect sense in the class diagram to give it a read and a write function. Yet when it came down to actually writing them I realized they were literally the same function with just one line of code changed (read vs write function call), so to avoid code duplication I ended up implementing a do_io function with a parameter that distinguishes between operations. Goodbye original design. This is not a terribly disruptive change, but it happens often and can happen in more critical parts of the program as well, so I can't help but wondering if there's a point to design more detail than a general outline, at least when it comes to the program's architecture (obviously when you are specifying an API you have to spell everything out). This might be just the result of my inexperience in doing design, but on the other hand we have agile methodologies which sort of say "we give up on planning far ahead, everything is going to change in a few days anyway", which is often how I feel. So, how exactly should I "use" design?

• How would I implement this application idea?

  - by Mike Wills

  I am a D&D gamer and a developer that has mostly worked with ASP.NET applications professionally. I have written some chat bots in Node.js and I have only played a little with PHP but wrote nothing serious. I have had inspiration to create a site that allows a person to keep track of characters (aka the character sheet). I am thinking of using this as a learning opportunity to learn noSQL and to write a full javascript front-end. I want this application to save the value as I change it. So if I edit the armor class, it is saved immediately instead of waiting until I hit the submit button. I think that will make it easier to use while gaming and not losing anything because I forgot to save the change. I have never done anything like this. How do you implement this style of application? Is there a tutorial or howto to get me on the right path? While I would really like to use ASP.NET but I don't have a Windows server to publish on (and I really can't afford to pay for a service). What language that runs on Linux would work well for this type of application? Note: I feel noSQL would work in this case because of the sheer number of tables required to create something like this in SQL.
