  • Finding links among many written and spoken thoughts

    - by Peter Fren
    So... I am using a digital voice recorder to record anything I see important, ranging from business to private, from rants to new business ideas. Every finalized idea is one wma-file. I wrote a program to sort the wma-files into folders. From time to time I listen to the wma-files, convert them to text(manually) and insert them into a mindmap with mindmanager, which I sort hierarchically by area and type in turn. This works very well, no idea is being lost, when I am out of ideas for a special topic, I listen to what I said and can get started again. What could a search system look like that finds links between thoughts(written in the mindmap and in the wma files) or in general gives me good search results even when the keyword I searched for is not present but a synonym of it or related topic(for instance flower should output entries containing orchid aswell, even if they contain orchid but not the very keyword flower). I prefer something ready-made but small adjustments to a given system are fine aswell. How would you approach this task?

  • A new mission statement for my school's algorithms class

    - by Eric Fode
    The teacher at Eastern Washington University that is now teaching the algorithms course is new to eastern and as a result the course has changed drastically mostly in the right direction. That being said I feel that the class could use a more specific, and industry oriented (since that is where most students will go, though suggestions for an academia oriented class are also welcome) direction, having only worked in industry for 2 years I would like the community's (a wider and much more collectively experienced and in the end plausibly more credible) opinion on the quality of this as a statement for the purpose an algorithms class, and if I am completely off target your suggestion for the purpose of a required Jr. level Algorithms class that is standalone (so no other classes focusing specifically on algorithms are required). The statement is as follows: The purpose of the algorithms class is to do three things: Primarily, to teach how to learn, do basic analysis, and implement a given algorithm found outside of the class. Secondly, to teach the student how to model a problem in their mind so that they can find a an existing algorithm or have a direction to start the development of a new algorithm. Third, to overview a variety of algorithms that exist and to deeply understand and analyze one algorithm in each of the basic algorithmic design strategies: Divide and Conquer, Reduce and Conquer, Transform and Conquer, Greedy, Brute Force, Iterative Improvement and Dynamic Programming. The Question in short is: do you agree with this statement of the purpose of an algorithms course, so that it would be useful in the real world, if not what would you suggest?

  • Shared to Dedicated or Amazon CloudFront to improve performances and keep secured?

    - by user978548
    I have a Wordpress which currently takes about 1.8s to 2.5s for the home page to completely load in my country. The page weight is about 700Ko (static content included). In order to increase performances, I'm considering two solutions: Switching to a dedicated host. Using amazon s3 cloudfront to serve static contents. My current shared hosting have servers in a neighboring country but not exactly in mine, and both amazon and the dedicated hosting have some, so that's already an advantage. So considering all that, I still have three questions remaining: Currently having a low traffic (100 unique visitors/days, but growing) will it make a huge difference between my shared hosting and a dedicated server ? Knowing that I already use a cookie-less domain to deliver static contents (but using a redirection to the same server), would using amazon s3 make a real difference ? Talking about the cons of dedicated vs amazon s3, if I choose for the dedicated server something like Ubuntu server and do daily package updates and have only port 80 open, would it be sufficient in terms of security (in comparison with my current shared hosting which manage everything for me) ?

  • High Performance SQL Views Using WITH(NOLOCK)

    - by gt0084e1
    Every now and then you find a simple way to make everything much faster. We often find customers creating data warehouses or OLAP cubes even though they have a relatively small amount of data (a few gigs) compared to their server memory. If you have more server memory than the size of your database or working set, nearly any aggregate query should run in a second or less. In some situations there may be high traffic on from the transactional application and SQL server may wait for several other queries to run before giving you your results. The purpose of this is make sure you don’t get two versions of the truth. In an ATM system, you want to give the bank balance after the withdrawal, not before or you may get a very unhappy customer. So by default databases are rightly very conservative about this kind of thing. Unfortunately this split-second precision comes at a cost. The performance of the query may not be acceptable by today’s standards because the database has to maintain locks on the server. Fortunately, SQL Server gives you a simple way to ask for the current version of the data without the pending transactions. To better facilitate reporting, you can create a view that includes these directives. CREATE VIEW CategoriesAndProducts AS SELECT * FROM dbo.Categories WITH(NOLOCK) INNER JOIN dbo.Products WITH(NOLOCK) ON dbo.Categories.CategoryID = dbo.Products.CategoryID In some cases quires that are taking minutes end up taking seconds. Much easier than moving the data to a separate database and it’s still pretty much real time give or take a few milliseconds. You’ve been warned not to use this for bank balances though.

  • Preventing possible burnout in a junior dev, or perhaps I'm not doing enough?

    - by m.edmondson
    I'm a software developer with 5 years experience over 3 companies. Within the last year a junior (brand new to the industry) has started at my current employer. I believe he is an excellent developer, who always delivers and is skilled as solving complex problems. However I'm slightly concerned that he is possibly applying himself too much for the following reasons: He begins work approximately 2 hours before most (and is expected) In his free time he has developed an application that was clearly months worth of work that is specific to our employer I and the team are completely greatful for all he is doing, and is clearly an asset to our team. However I'm worried that this is not sustainable. I can almost see that he has the same enthusiasm that I had when I began coding for work, however over the years I've realised that extra curricular work not only doesn't progress your career, but eats into your all important free time. The question I'm asking is: Should I advise him to take things a bit more slowly? Or perhaps I need to learn from him and do more for my employer out of hours?

  • TechEd 2010 - New Orleans

    - by gjfox
    We're a little more than half way through TechEd 2010 in New Orleans and I am having a hard time finding interesting breakout sessions to attend.  Laura Chappell has completed all of her sessions, and Andy Malone is almost done.  Laura's sessions on Wireshark have been amazing.  Andy is always entertaining and informative.  I did sit through a session this afternoon on IPv6 that was interesting.  I will spend the final day in the Hands on Labs area working through some PowerShell, and Communication Server 14 labs.  The speakers for two of my breakouts had written interesting books.  I went to the conference bookstore to pick them up and found both to be sold out.  They did offer to ship the books to me with the TechEd 20 percent discount. I'm not real sure who thought it would be a good idea to hold a conference in June in New Orleans.  It has been HUMID.  On top of that TechEd 2011 will be in my hometown, Atlanta.

  • PowerShell & SQL Compare

    - by Grant Fritchey
    Just a quick blog post to share a couple of scripts for using PowerShell to call SQL Compare. This is an example from my session at SQL in the City on setting up a sandbox development process. This just runs a compare between a set of scripts and a database and deploys it. set-Location “c:\Program Files (x86)\Red Gate\SQL Compare 10\”; ./sqlcompare /s2:DOJO /db2:MovieManagement_Sandbox /sourcecontrol1 /vu1:grant /vp1:12345 /r1:HEAD /sfx:scripts.xml /sync /mfx:migrations.xml /verbose; I would not recommend using the /verbose output for real automation, but I’m showing off how the tool works. This particular script does a compare straight from source control to a database on my server. You can use variables where I’ve hard coded. That’s it. Works great. Just wanted to share it out there. I have others that I’ll track down and put up here.

  • Grouping a comma separated value on common data [closed]

    - by Ankit
    I have a table with col1 id int, col2 as varchar (comma separated values) and column 3 for assigning group to them. Table looks like col1 col2 group .............................. 1 2,3,4 2 5,6 3 1,2,5 4 7,8 5 11,3 6 22,8 This is only the sample of real data, now I have to assign a group no to them in such a way that output looks like col1 col2 group .............................. 1 2,3,4 1 2 5,6 1 3 1,2,5 1 4 7,8 2 5 11,3 1 6 22,8 2 The logic for assigning group no is that every similar comma separated value of string in col2 have to be same group no as every where in col2 where '2' is there it has to be same group no but the complication is that 2,3,4 are together so they all three int value if found in any where in col2 will be assigned same group. The major part is 2,3,4 and 1,2,5 both in col2 have 2 so all int 1,2,3,4,5 have to assign same group no. Tried store procedure with match against on col2 but not getting desired result Most imp (I can't use normalization, because I can't afford to make new table from my original table which have millions of records), even normalization is not helpful in my context. This question is also on stackoverflow with bounty on this link Achieved so far:- I have set the group column auto increment and then wrote this procedure:- BEGIN declare cil1_new,col2_new,group_new int; declare done tinyint default 0; declare group_new varchar(100); declare cur1 cursor for select col1,col2,`group` from company ; DECLARE CONTINUE HANDLER FOR NOT FOUND SET done=1; open cur1; REPEAT fetch cur1 into col1_new,col2_new,group_new; update company set group=group_new where match(col2) against(concat("'",col2_new,"'")); until done end repeat; close cur1; select * from company; END This procedure is working, no syntax mistake but the problem is that I am not achieving the desired result exactly.

  • Heading to GTC 2010

    - by Daniel Moth
    Next week the GPU Technology Conference (GTC) 2010 takes place in San Jose, CA and I am lucky enough to be attending the entire week. It has been an extremely long time (in fact, I can't remember the last time) where I am registered as an attendee at a conference (full pass/access) without being a speaker *and* without having any booth duty! Having said that, we (our team at Microsoft) will be running GPU debugging UX studies throughout the entire week (similar to what I had previously advertised). If you are attending GTC 2010 and you are interested, look for the related flyer in your conference bag. The conference is an excellent opportunity to connect in-person with various individuals that I have only met virtually. From an educational perspective there is a very long and interesting session list, with multiple concurrent slots, making it very hard to choose between them, but I have managed to create my (packed) schedule. I am most looking forward to sessions on the programming languages and tools, both from Microsoft and MS partners. For full conference details, visit the GTC 2010 official page. Comments about this post welcome at the original blog.

  • Where does jQuery fit-in with frameworks like JavaScriptMVC, BackboneJS, SproutCore and Knockout?

    - by Prisoner ZERO
    I have been happily using JQuery for the last 2 years and have been quite sucessful creating some really cool functionality with it...so I am very comfortable with it. I also beleive the future of the web will continue on the current client-side path. However... The next challenge seems to be coming in the form of various controller frameworks: KnockoutJS, BackboneJS, SproutCore, JavaScriptMVC (the list goes on). Additonally, there are some great AMD Loader tools for use like RequireJS or LabJS etc. However, jQuery now has define and then capabilities baked-in. It's getting harder-and-harder to keep track of it all... And now, my task seems to be to evaluate/decide-on a strategic-direction for using some form of either an MVC or MVVM framework client-side...but I have so many questions. Where does JQuery fit-in with the various controller-frameworks mentioned above? Is JQuery used alongside each or do some of them have their own 'JQuery-styled version' baked-in? Are tools like RequireJS still needed if you implement one of the various controller-frameworks mentioned above? Does the define and then capabilities baked-into JQuery now supercede the AMD Loader mentioned above? Which one seems most modular? (see notes below) NOTES: One thing I don't want in any future-framework is the requirement of having to take-in vast amounts of functionality that I don't use. Meaning, I would rather use a framework that is truly modular. For example, to use jQuery UI you have to take-in a lot other core libraries that you might not actually use. I will be experimenting with each one, but some REAL feedback would be great. I've seen some 'similar' questions, but none have really answered the above skew. Thanks in advance!

  • Microsoft Dev Days &ndash; Johannesburg 2010

    - by MarkPearl
    So I am half way through dev days in Johannesburg. It has been quite an interesting day… Maybe it is me, but this year it hasn’t been as OMG as at previous conferences. A few things that stood out though… 1) This is the first time I have had to queue in a line to use the gents toilets before – yes, a true sign that we are at a typically male dominated industry event in this country – the men’s toilets were jam packed – the ladies if there were any there didn’t have a problem. 2) Bart De Smet presentation still rocks – I am a fan of Bart’s and once again his presentation was great. Something that I am going to look into in more depth which I think is a new feature in .Net is called Code Contracts. 3) I have got to get into Silverlight more… I have known this for a long time and have dabbled in it for a while, but Silverlight in my opinion will become the main platform for “hosting” applications. So… 3 things so far, hopefully I get some OMG’s from the rest of the day…

  • Unity - Invert Movement Direction

    - by m41n
    I am currently developing a 2,5D Sidescroller in Unity (just starting to get to know it). Right now I added a turn-script to have my character face the appropriate direction of movement, though something with the movement itself is behaving oddly now. When I press the right arrow key, the character moves and faces towards the right. If I press the left arrow key, the character faces towards the left, but "moon-walks" to the right. I allready had enough trouble getting the turning to work, so what I am trying is to find a simple solution, if possible without too much reworking of the rest of my project. I was thinking of just inverting the movement direction for a specific input-key/facing-direction. So if anyone knows how to do something like that, I'd be thankful for the help. If it helps, the following is the current part of my "AnimationChooser" script to handle the turning: Quaternion targetf = Quaternion.Euler(0, 270, 0); // Vector3 Direction when facing frontway Quaternion targetb = Quaternion.Euler(0, 90, 0); // Vector3 Direction when facing opposite way if (Input.GetAxisRaw ("Vertical") < 0.0f) // if input is lower than 0 turn to targetf { transform.rotation = Quaternion.Lerp(transform.rotation, targetf, Time.deltaTime * smooth); } if (Input.GetAxisRaw ("Vertical") > 0.0f) // if input is higher than 0 turn to targetb { transform.rotation = Quaternion.Lerp(transform.rotation, targetb, Time.deltaTime * smooth); } The Values (270 and 90) and Axis are because I had to turn my model itself in the very first place to face towards any of the movement directions.

  • How should I determine my rates for writing custom software?

    - by Carson Myers
    For a custom software that will likely take a year or more to develop, how would I go about determining what to charge as a consultant? I'm having a hard time coming up with a number, and searches online are providing vastly different numbers (between $55/hr and $300/hr). I don't want to shoot too low because it's going to take me so much time (and I'm deferring my education for this project). I also don't want to shoot too high and get unpleasant looks and demand for justification. FWIW I live in Canada, and have approx. 10 years of development experience. I've read the "take your salary and divide it by 1000" rule of thumb, but the thing is I don't have a salary. Currently I'm just doing fairly small programming tasks for a friend who is starting a marketing company, pricing each task fairly arbitrarily. I don't know what I would make over the course of a year doing it, but it would be incredibly low. My responsibilities for the project would be the architecture, programming, database, server, and UX to some degree. It's going to be a public facing web service so I will also need to put a lot of effort into security and scalability. Any advice or experience?

  • Moving player in direciton camera is facing

    - by Samurai Fox
    I have a 3rd person camera which can rotate around the player. My problem is that wherever camera is facing, players forward is always the same direction. For example when camera is facing the right side of the player, when I press button to move forward, I want player to turn to the left and make that the "new forward". My camera script so far: using UnityEngine; using System.Collections; public class PlayerScript : MonoBehaviour { public float RotateSpeed = 150, MoveSpeed = 50; float DeltaTime; void Update() { DeltaTime = Time.deltaTime; transform.Rotate(0, Input.GetAxis("LeftX") * RotateSpeed * DeltaTime, 0); transform.Translate(0, 0, -Input.GetAxis("LeftY") * MoveSpeed * DeltaTime); } } public class CameraScript : MonoBehaviour { public GameObject Target; public float RotateSpeed = 170, FollowDistance = 20, FollowHeight = 10; float RotateSpeedPerTime, DesiredRotationAngle, DesiredHeight, CurrentRotationAngle, CurrentHeight, Yaw, Pitch; Quaternion CurrentRotation; void LateUpdate() { RotateSpeedPerTime = RotateSpeed * Time.deltaTime; DesiredRotationAngle = Target.transform.eulerAngles.y; DesiredHeight = Target.transform.position.y + FollowHeight; CurrentRotationAngle = transform.eulerAngles.y; CurrentHeight = transform.position.y; CurrentRotationAngle = Mathf.LerpAngle(CurrentRotationAngle, DesiredRotationAngle, 0); CurrentHeight = Mathf.Lerp(CurrentHeight, DesiredHeight, 0); CurrentRotation = Quaternion.Euler(0, CurrentRotationAngle, 0); transform.position = Target.transform.position; transform.position -= CurrentRotation * Vector3.forward * FollowDistance; transform.position = new Vector3(transform.position.x, CurrentHeight, transform.position.z); Yaw = Input.GetAxis("Right Horizontal") * RotateSpeedPerTime; Pitch = Input.GetAxis("Right Vertical") * RotateSpeedPerTime; transform.Translate(new Vector3(Yaw, -Pitch, 0)); transform.position = new Vector3(transform.position.x, transform.position.y, transform.position.z); transform.LookAt(Target.transform); } }

  • Am I misunderstanding chown and chmod?

    - by isomorphismes
    I want to either extend the size of my guest partition or figure out how to copy stuff from the guest partition to my normal /home directory. (Because of some other problems I can only run Xorg as guest, but I can log into virtual console as myself or root.) Here's the motivation: I want to torrent a large file. It's larger than my guest filesystem. But I have plenty of space on my real drive, I just can't log into it graphically. So I tried to set up a "pipe" to get the file out of the tmpfs. I did: su -u myself #catch mkdir ~/receiver_dir sudo su cd /tmp/guest-lkj567UIO/ #throw ln -s mario_pipe /home/myself/receiver_dir chown -R guest-lkj567UIO /home/myself/receiver_dir chown -R guest-lkj567UIO /tmp/guest-lkj567UIO/mario_pipe chmod -R a+rw /home/myself/receiver_dir chmod -R a+rw /tmp/guest-lkj567UIO/mario_pipe su -u guest-lkj567UIO cd /tmp/guest-lkj567UIO cd mario_pipe touch something #success! However, when I try to torrent to /tmp/guest-lkj567UIO/mario_pipe, Transmission says I don't have write permissions. But it looks like I just wrote there? And that everybody (a+rw) can write there in fact? Maybe this indicates I don't actually understand chown and chmod but nothing from their man pages pops out.

  • Is micro-optimisation important when coding?

    - by BozKay
    I recently asked a question on stackoverflow.com to find out why isset() was faster than strlen() in php. This raised questions around the importance of readable code and whether performance improvements of micro-seconds in code were worth even considering. My father is a retired programmer, I showed him the responses and he was absolutely certain that if a coder does not consider performance in their code even at the micro level, they are not good programmers. I'm not so sure - perhaps the increase in computing power means we no longer have to consider these kind of micro-performance improvements? Perhaps this kind of considering is up to the people who write the actual language code? (of php in the above case). The environmental factors could be important - the internet consumes 10% of the worlds energy, I wonder how wasteful a few micro-seconds of code is when replicated trillions of times on millions of websites? I'd like to know answers preferably based on facts about programming. Is micro-optimisation important when coding? EDIT : My personal summary of 25 answers, thanks to all. Sometimes we need to really worry about micro-optimisations, but only in very rare circumstances. Reliability and readability are far more important in the majority of cases. However, considering micro-optimisation from time to time doesn't hurt. A basic understanding can help us not to make obvious bad choices when coding such as if (expensiveFunction() && counter < X) Should be if (counter < X && expensiveFunction()) (example from @zidarsk8) This could be an inexpensive function and therefore changing the code would be micro-optimisation. But, with a basic understanding, you would not have to because you would write it correctly in the first place.

  • Decreasing the Height of the PinkMatter Flamingo Ribbon Bar

    - by Geertjan
    The one and only thing prohibiting wide adoption of PinkMatter's amazing Flamingo ribbon bar integration for NetBeans Platform applications (watch the YouTube movie here and follow the tutorial here) is... the amount of real estate taken up by the height of the taskpane: I was Skyping with Bruce Schubert about this and he suggested that a first step might me to remove the application menu. OK, once that had been done there was still a lot of height: But then I configured a bit further and now have this, which is pretty squishy but at least shows there are possibilities: How to get to the above point? Get the PinkMatter Flamingo ribbon bar from java.net (http://java.net/projects/nbribbonbar), which is now the official place where it is found, and then look in the "Flaming Integration" module. There you'll find com.pinkmatter.modules.flamingo.LayerRibbonComponentProvider. Do the following: Comment out "addAppMenu(ribbon);" in "createRibbon()". That's the end of the application menu. Change the "addTaskPanes(JRibbon ribbon)" method from this... private void addTaskPanes(JRibbon ribbon) { RibbonComponentFactory factory = new RibbonComponentFactory(); for (ActionItem item : ActionItems.forPath("Ribbon/TaskPanes")) {// NOI18N ribbon.addTask(factory.createRibbonTask(item)); } } ...to the following: private void addTaskPanes(JRibbon ribbon) { RibbonComponentFactory factory = new RibbonComponentFactory(); for (ActionItem item : ActionItems.forPath("Ribbon/TaskPanes")) { // NOI18N RibbonTask rt = factory.createRibbonTask(item); List<AbstractRibbonBand<?>> bands = rt.getBands(); for (AbstractRibbonBand arb : bands) { arb.setPreferredSize(new Dimension(40,60)); } ribbon.addTask(rt); } } Hurray, you're done. Not a very great result yet, but at least you've made a start in decreasing the height of the PinkMatter Flamingo ribbon bar. If anyone gets further with this, I'd be very happy to hear about it!

  • How to handle multiple effect files in XNA

    - by Adam 'Pi' Burch
    So I'm using ModelMesh and it's built in Effects parameter to draw a mesh with some shaders I'm playing with. I have a simple GUI that lets me change these parameters to my heart's desire. My question is, how do I handle shaders that have unique parameters? For example, I want a 'shiny' parameter that affects shaders with Phong-type specular components, but for an environment mapping shader such a parameter doesn't make a lot of sense. How I have it right now is that every time I call the ModelMesh's Draw() function, I set all the Effect parameters as so foreach (ModelMesh m in model.Meshes) { if (isDrawBunny == true)//Slightly change the way the world matrix is calculated if using the bunny object, since it is not quite centered in object space { world = boneTransforms[m.ParentBone.Index] * Matrix.CreateScale(scale) * rotation * Matrix.CreateTranslation(position + bunnyPositionTransform); } else //If not rendering the bunny, draw normally { world = boneTransforms[m.ParentBone.Index] * Matrix.CreateScale(scale) * rotation * Matrix.CreateTranslation(position); } foreach (Effect e in m.Effects) { Matrix ViewProjection = camera.ViewMatrix * camera.ProjectionMatrix; e.Parameters["ViewProjection"].SetValue(ViewProjection); e.Parameters["World"].SetValue(world); e.Parameters["diffuseLightPosition"].SetValue(lightPositionW); e.Parameters["CameraPosition"].SetValue(camera.Position); e.Parameters["LightColor"].SetValue(lightColor); e.Parameters["MaterialColor"].SetValue(materialColor); e.Parameters["shininess"].SetValue(shininess); //e.Parameters //e.Parameters["normal"] } m.Draw(); Note the prescience of the example! The solutions I've thought of involve preloading all the shaders, and updating the unique parameters as needed. So my question is, is there a best practice I'm missing here? Is there a way to pull the parameters a given Effect needs from that Effect? Thank you all for your time!

  • Dealing with an Idiot [closed]

    - by inspectorG4dget
    I'm a 4th year University Computer Science student, and I have this problem, that I don't seem to be able to find a straight answer to: As a 4th year computer science student, I spend more time in the computer lab on campus, than even my own home. This means that getting along with everyone else here is very important to me. In most cases, this is not an issue because my interactions with almost all the people here fall into one of the following categories: Let me help you, junior Hi fellow student in a course I'm taking, I'm having trouble with this assignment question. Can you give me a hint as to how you solved it? Hi fellow student in a course I'm taking, This is how I solved the problem that you're stuck on. Hope it helps Hi fellow student, I noticed that you're working on a project, using a library that I'm interested in. Can we setup a time so I can learn about this library from you? This model of interaction works very well for me. However, there is one fellow student, who manages to make my life hell beyond all of this (his name is not important, let's just call him "Sam"). He seems to be always (pardon my crass description) high and completely unwilling to contribute to a constructive, academic conversation. He's a pretty smart guy, but just comes across as (I hate to say something like this about a fellow student, but) an imbecile. He also has ignorant opinions on important topics, some of which pertain to my specialization (AI, NLP, etc), and when I try to explain to him why he's wrong, all he does is insult me and put me in a foul mood. I have tried ignoring him (sitting somewhere else in the lab, headphones, etc), but he seems to like doing this because he approaches me and no amount of "leave me alone" seems to do the trick. Can anyone please suggest to me how to deal with this man in a civil way? Thank you

  • RESTFul: state changing actions

    - by Miro Svrtan
    I'am planning to build RESTfull API but there are some architectural questions that are creating some problems in my head. Adding backend bussiness logic to clients is option that I would like to avoid since updating multiple client platforms is hard to maintain in real time when bussiness logic can rapidly change. Lets say we have article as a resource ( api/article ), how should we implement actions like publish, unpublish,activate or deactivate and so on but to try to keep it as simple as possible? 1) Should we use api/article/{id}/{action} since a lot of backend logic can happen there like pushing to remote locations or change of multiple properties. Probably the hardest thing here is that we need to send all article data back to API for updating and multiuser work could not be implemented. For instance editor could send 5 seconds older data and overwrite fix that some other journalist just did 2 seconds ago and there is no way that I could explain to clients this since those publishing an article is really not in any way connected to updating the content. 2) Creating new resource can also be an option, api/article-{action}/id , but then returned resource would not be article-{action} but article which I'am not sure if this is proper. Also in server side code article class is handling actuall work on both resource and I'm not sure if this goes against RESTfull thinking Any suggestions are welcomed..

  • SharePoint Unit Testing and Load Testing Finally?

    - by Kit Ong
    It has always been a real pain to incorporate extensive SharePoint Unit Testing and Load Testing in a project, could Visual Studio 2012 finally make this easier? It certaining looks like it, here's a brief overview on SharePoint support in Visual Studio 2012. Load testing – We now support load testing for SharePoint out of the box. This is more involved than you might imagine due to how dynamic SharePoint is. You can’t just record a script and play it back – it won’t work because SharePoint generates and expects dynamic data (like GUIDs). We’ve built the extensions to our load testing solution to parse the dynamic SharePoint data and include it appropriately in subsequent requests. So now you can record a script and play it back and we will dynamically adjust it to match what SharePoint expects.Unit testing – One of the big problems with unit testing SharePoint is that most code requires SharePoint to be running and trying to run tests against a live SharePoint instance is a pain. So we’ve built a SharePoint “emulator” using our new VS 2012 Fakes & Stubs capability. This will make unit testing of SharePoint components WAY easier.Read more in the link belowhttp://blogs.msdn.com/b/bharry/archive/2012/09/12/visual-studio-update-this-fall.aspx

  • Cloned partition not seen correctly by disk utility & gparted

    - by enrico
    Some days ago I cloned my /dev/sda1 partition with clonezilla in partition-to-partition mode to /dev/sda3. It worked, but now that I've finished the setup of system in /dev/sda3, I wanna reinstall /dev/sda1 for other stuffs. This partition is NOT mounted, but ubuntu's DISK UTILITY thinks it is, while it doesn't see as mounted the currently active / partition /dev/sda3. This is the df- TH output : Filesystem Type Size Used Avail Use% Mounted on /dev/sda3 ext4 32G 6.2G 24G 21% / udev devtmpfs 2.2G 13k 2.2G 1% /dev tmpfs tmpfs 845M 906k 844M 1% /run none tmpfs 5.3M 0 5.3M 0% /run/lock none tmpfs 2.2G 115k 2.2G 1% /run/shm /dev/sdb1 fuseblk 321G 147G 174G 46% /Dati Gparted instead, sees /dev/sda1 as NOT mounted (checked with Information option), but it display the BOOT flag on this partition, while the real booted partition /dev/sda3, hasn't it. If I try to format the /dev/sda1 partition, it gives me this error : GParted 0.8.1 --enable-libparted-dmraid Libparted 2.3 Format /dev/sda1 as ext2 00:00:02 ( ERROR ) calibrate /dev/sda1 00:00:00 ( SUCCESS ) path: /dev/sda1 start: 2048 end: 62500863 size: 62498816 (29.80 GiB) set partition type on /dev/sda1 00:00:02 ( SUCCESS ) new partition type: ext2 create new ext2 file system 00:00:00 ( ERROR ) mkfs.ext2 -L "" /dev/sda1 mke2fs 1.41.14 (22-Dec-2010) /dev/sda1 is mounted; will not make a filesystem here! How is possible to correct this behaviour ? Is this due to some lacking option in clonezilla phase ? TIA Enrico

  • Do you know about the Visual Studio 2010 Architecture Guidance?

    - by Martin Hinshelwood
    If you have not seen the Visual Studio 2010 Architectural Guidance from the Visual Studio ALM Rangers then you are missing out. I have been spelunking the TFS Guidance recently and I discovered the Visual Studio 2010 Architectural Guidance. This is not an in-depth look at the capabilities of the architectural tools that shipped with Visual Studio 2010 Ultimate, but is instead a set of samples that lead you by example through real world scenarios. There is practical guidance and checklists to help guide lead developers and architects through the common challenges in understanding both existing and new applications. The content concentrates on practical guidance for Visual Studio 2010 Ultimate and is focused on modelling tools. There is integration into Visual Studio so all you need to do to access it is select “Architecture | Visual Studio ALM Rangers – Architecture Guidance”. Figure: Accessing the Architecture guidance is easy This brings up an inline version of the documentation and a kind of Explorer that lets you pick the tasks you want to perform and takes you strait to that part of the Guidance. Figure: Access the Guidance from right within Visual Studio 2010 This is a big help when you just want to figure out how to do something and can’t be bothered searching for and through the content in the provided Word documents. The Question and Answer section is full of useful content and there are six Hands-On-Labs to sink your teeth into: Creating extensions with the feature extension Explore an Existing System Scenario Extensibility Layer Diagrams New Solution Scenario Reusable Architecture Scenario Validation an Architecture Scenario I’m sold! Where can i get my hands on this fantastic content? Download the Visual Studio 2010 Architecture Tooling Guidance and if you like it don’t forget to add a review to make the team that put it together in their spare time feel all the mere loved.
