  • Real Time Monitoring System using .net [closed]

    - by sameer
    I need to develop the application which display the dashboard where data from various SQL DB is fetched from different servers and displayed. Now this need to happen real time we can have refresh time say 5 min. Here is my thought, suggest if anything is wrong. 1) To Develop the Windows Service to accumulate the data from various SQL Server Instance. 2) Then Persist those details into SQL DB from which Dashboard will displayed on the web page. 3) Fetch of data from Windows service will be trigger every x minutes. 4) SQL Server Instance details will be stored in SQL DB which Windows Service will be referring. Thus this approach make sense. Thanks..

  • What utility is like Ten Clips, providing an enumerated clipboard?

    - by Aaron Newton
    A very useful (Windows) utility I use is TenClips - http://www.paludour.net/TenClips.html It allows you to create enumerated clipboards/emacs-like buffers easily using ctrl + f1, ctrl + f2, ctrl + f3, etc., copy to the clipboard in the first buffer, switch to the second buffer, copy without loosing our first buffer, switch back to the first buffer and paste, switch to the second buffer and paste and so forth. Does something like this exist for Ubuntu? The closest post I could find was Looking for an application that saves clipboard history which recommended Parcellite (http://parcellite.sourceforge.net/?page_id=2) - which keeps the history - but this is not quite what I'm after. If not I might make this a pet project :D

  • How well do free-to-open-source-projects policies work in practice?

    - by Steve314
    In comparison with an open source license and requesting donations, is a free-for-open-source-projects (or free for non-commercial developers) closed source and otherwise commercial project likely to get more license fees? Or just to alienate potential users? Assume the project has value to programmers - I'm looking for generalizations here, though specific examples comparing existing projects will be very interesting. What I have in mind involves code generating programming utilities. And one issue I can think of, either way, is a near total inability to enforce any license restrictions. After all, I can't go around the internet demanding that everyone show me their source code just in case!

  • The year ahead, 2011.

    - by andrewstopford
    When I look back at last years look at 2010 my blogging rate has not changed much (I suspect this is largely down to using Twitter a lot) but my interests this year have developed a lot further. My view on 2010 would be that Microsoft would commit more to OSS, while I wanted to see more hires from that audience and more projects on Outercurve foundation instead there has been support for JQuery and Gems (aka NuGet). I would love to see more from Microsoft on the OSS front in 2011, Outercurve could become like the Apache foundation with enough support. Staying on the Microsoft front I predict that 2011 will bring the following. C# 5.0 will go RTM (still no MOP though) The next release of VS will go alpha or early beta MS MVC 4.0 (I think by Mix time) and maybe this release will get a command line. I also suspect that Microsoft will want to target the tablet market with WP7 in 2011 (Mix 2011 maybe...). I also predict the following Java will fork with Apache\Google. Oracle will then take them to court and the whole thing will boil right through 2011 (Java have had enough court cases, come on guys). Java and the JVM will sadly not move forward at all in 2011. Android will cause Apple a serious headache, both the smartphone and tablet market will see figures cut from Apple share. By the end of 2011 the current 70% apple market share will be 40-50%. As the features, performance and price of Android devices gets ever better Apple will be left out in the open. Lastly after 7 years I intend to move this blog away from weblogs. In 2011 I will be exploring Java, Ruby\Rails and Android and such subjects don't make sense to talk about it here. See you in 2011.

  • How to create a screencast?

    - by Riccardo Murri
    How can I create a screencast on Ubuntu? What applications are available? The app I'm looking for has ideally all of these features: Can record in a format that can be played back easily on any platform and/or accepted by youtube or another popular video site Can record just a window (instead of the whole screen), possibly selecting it with a mouse click Can start recording after a configurable delay (e.g., I launch the app and have time to do arrangements to my desktop/window before actual recording starts)

  • At what point does "constructive" criticism of your code become unhelpful?

    - by user15859
    I recently started as a junior developer. As well as being one of the least experienced people on the team, I'm also a woman, which comes with all sorts of its own challenges working in a male-dominated environment. I've been having problems lately because I feel like I am getting too much unwarranted pedantic criticism on my work. Let me give you an example of what happened recently. Team lead was too busy to push in some branches I made, so he didn't get to them until the weekend. I checked my mail, not really meaning to do any work, and found that my two branches had been rejected on the basis of variable names, making error messages more descriptive, and moving some values to the config file. I don't feel that rejecting my branch on this basis is useful. Lots of people were working over the weekend, and I had never said that I would be working. Effectively, some people were probably blocked because I didn't have time to make the changes and resubmit. We are working on a project that is very time-sensitive, and it seems to me that it's not helpful to outright reject code based on things that are transparent to the client. I may be wrong, but it seems like these kinds of things should be handled in patch type commits when I have time. Now, I can see that in some environments, this would be the norm. However, the criticism doesn't seem equally distributed, which is what leads to my next problem. The basis of most of these problems was due to the fact that I was in a codebase that someone else had written and was trying to be minimally invasive. I was mimicking the variable names used elsewhere in the file. When I stated this, I was bluntly told, "Don't mimic others, just do what's right." This is perhaps the least useful thing I could have been told. If the code that is already checked in is unacceptable, how am I supposed to tell what is right and what is wrong? If the basis of the confusion was coming from the underlying code, I don't think it's my responsibility to spend hours refactoring a whole file that someone else wrote (and works perfectly well), potentially introducing new bugs etc. I'm feeling really singled out and frustrated in this situation. I've gotten a lot better about following the standards that are expected, and I feel frustrated that, for example, when I refactor a piece of code to ADD error checking that was previously missing, I'm only told that I didn't make the errors verbose enough (and the branch was rejected on this basis). What if I had never added it to begin with? How did it get into the code to begin with if it was so wrong? This is why I feel so singled out: I constantly run into this existing problematic code, that I either mimic or refactor. When I mimic it, it's "wrong", and if I refactor it, I'm chided for not doing enough (and if I go all the way, introducing bugs, etc). Again, if this is such a problem, I don't understand how any code gets into the codebase, and why it becomes my responsibility when it was written by someone else, who apparently didn't have their code reviewed. Anyway, how do I deal with this? Please remember that I said at the top that I'm a woman, and I'm sure these guys don't usually have to worry about decorum when they're reviewing other guys' code, but honestly that doesn't work for me, and it's causing me to be less productive. I'm worried that if I talk to my manager about it, he'll think I can't handled the environment, etc.

  • How to I prevent decimal truncation in Word 2003 when a document is auto populated via a Web Service

    - by thomas.loughran
    I have a document template which is being auto populated via an external web service. The incoming data exists as a currency (e.g. 3.10) but when it is passed into the Word Document template the variable is truncated to remove any trailing 0's. I need the number to always appear with 2 decimals, even if they are both 0's. This is with the 2003 version of Word, I have not tested with other versions since all of our document templates need to be generated using that version of Word. I feel like this can be done with a Macro or a VB script but I have a very small amount of time & no experience with these tools - Any help is greatly appreciated!

  • The best AutoCAD 2010 Ubuntu alternative?

    - by onvas
    I'm looking for the best AutoCAD 2010 alternative for Ubuntu. Wine's support for the 2010 version isn't polished so I'm looking for Linux based similar programs. I know that this can be subjective so I'd like to know what's the best Ubuntu alternative which has the most similar, and significant features as that of AutoCAD 2010? I'm not familiar with the program because I'm researching this for my sister who is studying Aeronautical Engineering. Any help is appreciated. I'm using 12.04 64-bit on my ThinkPad R61i with 3.8GB memory and 160GB hard drive.

  • General List of Common Programming Errors

    - by javamonkey79
    As one journey's from apprentice to journeyman to master I've noticed that one accumulates a list of best practices for things they've been bitten by. Personally, I write most of my stuff in java & SQL so my list tends to be slated towards them. I've accumulated the following: When doing list removal, always reverse iterate Avoid adding items to a list you are currently iterating on Watch out for NullPointerExceptions Now, I know there are language specific "common errors" links out there like this one. And I'm also aware of the pragmatic programmer tips, Martin Fowler's "code smells". Does anyone know of any good lists out there of things like I've listed above (re: list removal, adding items, etc). My guess is that there are some good QA folks out there that can probably throw me a bone here. I'm not looking for things the compiler can catch - I'm looking for common things that cause bugs. In the event that there isn't a list out there already then I welcome posting your own findings here. Thanks in advance!

  • how to detect keylogger in windows that hooked up key-press?

    - by saber tabatabaee yazdi
    For security reasons we have to detect all key-loggers and log them in somewhere like windows events. I have piece of C# code that it is very easy to install all clients and up and running every day in system trays and no one can close it. We want to modify that code and send logs to central web service in our network (that this also web service is installed last year and receive and log all another security logs).

  • Web api authentication techniques

    - by Steve
    We have a asp.net MVC web service framework for serving out xml/json for peoples Get requests but are struggling to figure out the best way (fast, easy, trivial for users coding with javascript or OO languages) to authenticate users. It's not that our data is sensitive or anything, we just want users to register so we can have their email address to notify them of changes and track usage. In our previous attempt we had the username in the URI and would just make sure that username existed and increment db tables with usage. This was super basic but we'd notice people using demo as a username etc so we need it to be a little more sophisticated. What authentication techniques are available? What do the major players use/do.

  • Google Earth-Unsupported graphics card

    - by VIPaul
    I've just installed Google Earth on my PC,which runs Ubuntu 12.04 LTS. When I open Google Earth,a window pop-ups and says:"Unsupported Graphics Card Your graphics card does nor meet the minimum spec required to run Google Earth,which is a 3D accelerated card with shader support.It is strongly recommended that you try running Google Earth on a different machine or in a different rendering mode or upgrade to a newer graphics card.You may continue,but the application is unlikely to work." Maybe you'll say:"Buy a better graphics card!",but I used Google Earth on this machine an year ago,when I had Windows 7 & everything worked well,so my graphics card is good enough. The Linux version has bigger requirements than the Windows one or what???

  • how to uninstall sphinx server

    - by misterjinx
    I installed (from sources) yesterday sphinx server and didn't think of configuring it properly, so I left the default installation directory (/usr/local). Today I realized that it created all of it's directories inside that directory, instead of creating its own (as I wrongly thought). So today I started again the installation and specified explicitly the location where to install. After that I removed the previous directories from /usr/local that were created when the first installation was done (bin, etc, var). So I thought of giving it a test. I created the .conf file and wanted to run the indexer. But now, the indexer always tries to search the .conf file in the old location (obviously does not find anything) and when I specify where to find the .conf file it gives me errors for each of the configuration settings present. I know I did something wrong when I deleted manually those files and that's why I'm asking you if have any ideas how to correctly uninstall sphinx. Thank you.

  • Designing and refactoring of payment logic

    - by jokklan
    Im currently working on an application that helps users to coordinate dinner clubs and all related accounting. (A dinner club is where people in a group, take turns to cook for the rest and then you pay a small amount to participate. This is pretty normal in dorms and colleges where im from). However there is some different models that all have a price and the accounting aspect is therefore a little spread. We both have DinnerClub, ShoppingItem and are about to implement the third Payment when users pay their debts (or get refunded for expenses). Each of these have a "price" attribute and a users expense (that he or she needs refunded) is calculated by the total of these "prices" minus what other users have bought and he or she have used/participated in. My question is then if someone have some hints to refactor this bring all this behavior together in one place? For now have i thought about a Transaction class that are responsible for this behaviour, but I'm a little worried about the performance impact on having to query for another polymorphic record each time i want to show the price on dinner clubs and shopping items (i have a standard index page with a list for both so it's a lot of extra records being queried)...

  • Applying to a company while personally working on a comparable project

    - by Developer Art
    That's going to be an unusual question but here it goes. I'm entertaining the thought to send my docs to a place which develops a large web project of a social type. Social meaning people, communities, interaction and all that usual stuff. The issue is that I myself am working on something that falls into the category of social in my private time. Now the question. Is it wise to apply there under these circumstances? I think there may be issues of intellectual ownership if I develop something similar that exists or will exist in that company's work. On the other hand, the web of full of social places (even this site is one of them), many of them utilize the same ideas and move in the same direction and it seems to work for everyone. It's hard to come up with something which hasn't been tried yet by somebody else so it's all basically reuse of the commonly available ideas and experience. What I'm working on is not a functional equivalent, it's rather largely off. There may be some intersections, but on a large scale this is not an equivalent. And whatever features might coincide, they already exist everywhere on the web anyway. Also technology stacks are entirely different so the issue with directly copying out parts of the code is probably not applicable. I plan to say it up front that I'm engaged in a personal project of mine and let them see if it represents a problem for them. What do you think? Am I making things up or is there really an issue?

  • What is the architectural name for the set of data that enables UI choices?

    - by Richard Collette
    I have separate service methods that fetch business object data and the data for UI selection input such as radio buttons, check-boxes, combo-boxes, etc. I want to name my service methods that fetch the selection data appropriately. I am assuming that Model and ViewModel would not be part of the name because the selection data is but a portion of the Model or ViewModel. What might this set of data be named such that I can name my service method?

  • How do you balance the speed of Sprints with the customer's conservative adoption schedule?

    - by Cheeso
    I'd prefer to have sprints that last 3-4 weeks, but customers don't want to adopt new feature/function every 3-4 weeks. Existing customers are conservative and, once we meet their minimum bar for features and capabilities, they like to remain on a stable release for much longer than 4 weeks. Even a 3-month cycle would be pushing it for them. On the other hand, newer customers tend to have more feature requests, and are willing to follow sprints. But this willingness dissipates after we've met their bar. How do you balance the need for rapid sprints with the customer's conservative view of application change? I'm particularly interested in SaaS scenarios.

  • How should a JEE application store credentials for logging in to an external system?

    - by FGreg
    I am in a situation where I have a Web Application (WAR) that is accessing a REST service provided by another application. The REST service uses Basic HTTP Authentication. So that means the application calling the REST service needs to store user credentials somehow. To further complicate things, this is an enterprise, so there are different 'regions' the application moves through which will have different credentials for the same service (think local development, development region, integration region, user test region, production, etc...) My first instinct is that the credentials should be stored by the JEE container and the application should ask the container for the credentials (probably via JNDI?). I'm beginning to read about Java Authentication and Authorization Service (JAAS) but I'm not sure if that is the appropriate solution to this problem. How should a JEE application store credentials for logging in to an external system? A few more details about my WAR. It is a Spring-Integration project that has no front-end. The container I am working with is Websphere. I am using JEE 5 and Spring 4.0.1. To this point I have not needed to consider spring-security... does this situation mean I should re-evaluate that decision?

  • What could be a reason for cross-platform server applications developer to make his app work in multiple processes?

    - by Kabumbus
    So we consider a server app development - heavily loaded with messing with big data streams.An app will be running on one powerful server. a server app shall be developed in form of crossplatform application - so to work on Windows, Mac OS X and Linux. So same code many platforms for standing alone server architecture. We wonder what benefits does distributing applications not only over threads but over processes as wall would bring to programmers and to server end users and why? Some people sad to me that even having 48 cores, 4 process threads would be shared via OS throe all cores... is it true BTW?

  • Would this be considered Single Tenant or Multi-Tenant?

    - by Amy Anuszewski
    I'm sorry for this dumb, basic vocabulary question, but I've managed to confuse myself. As a company, we lease a managed server from a provider. In that sense, our server is a single tenant server. On this server, we have multiple customer databases. Each customer has its own database. We have been asked by a customer if we are a single tenant or a multi-tenant solution. From our perspective, we are the sole tenant of the server. But, what is the correct answer to the customer?
