  • How to instrument existing ASP.NET application?

    - by jkohlhepp
    We have several highly complex ASP.NET web applications that are used internally by hundreds of users. We are trying to figure out which areas of the applications to invest in to improve functionality, but we aren't sure which screens/features are more heavily used. So, ideally, I'd like to find a way to add a layer of instrumentation to the applications that gathers metrics on which buttons are being clicked, which text boxes are being used, etc. Are there any products / open source apps out there that will do this sort of instrumentation for ASP.NET? Obviously I could do it myself manually by going into the code and injecting logging statements everywhere but this would be a significant amount of work that will be hard to accomplish.

  • Quick ways to boost performance and scalability of ASP.NET, WCF and Desktop Clients

    - by oazabir
    There are some simple configuration changes that you can make on machine.config and IIS to give your web applications significant performance boost. These are simple harmless changes but makes a lot of difference in terms of scalability. By tweaking system.net changes, you can increase the number of parallel calls that can be made from the services hosted on your servers as well as on desktop computers and thus increase scalability. By changing WCF throttling config you can increase number of simultaneous calls WCF can accept and thus make most use of your hardware power. By changing ASP.NET process model, you can increase number of concurrent requests that can be served by your website. And finally by turning on IIS caching and dynamic compression, you can dramatically increase the page download speed on browsers and and overall responsiveness of your applications.

  • Why are Awstats, Webalizer, and Google Analytics results so different?

    - by Matt
    I realize that comparing Awstats and Webalizer to Google Analytics is like comparing apples to oranges, but each of them track at least basic statistics about visitors and pages. So why are there often very significant differences in their data? For example, comparing Analytics with Awstats using some numbers from a small site over the past week: Awstats 78 unique visitors 205 visits (2.62 visits/visitor) 1,072 pages (5.22 pages/visit) Google Analytics 115 unique visitors 240 visits (2.08 visits/visitor) 1,275 pages (5.31 pages/visit) They're similar on the number of visits, but page views and uniques are quite different. I'm familiar with discrepancies of a much higher magnitude on some larger sites, showing that this trend scales proportionally upward. What is the reason behind the different numbers, even when the data is quite trivial like unique visitors and page loads?

  • Architectural requirements Q&amp;A

    A few days ago I was contacted by Lianping Chen a doctoral researcher from the Irish Software Engineering Research Centre. Lianping is doing research on how to elicit architectural significant requirements and he asked me a few questions, which I though, might be interesting to a wider audience. 1. Do you agree that architecture design and requirements elicitation are usually in parallel or have a big time overlap? In other words, Architectural...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • App Store: Profitability for Game Developers

    - by Bunkai.Satori
    Recent days, I've been spending significant time in discovering chances of profitability of AppStore for developers. I have found many articles. Some of them are highly optimistic, while other are extremely skeptical. This article is extremely skeptical. It even claims to have backed its conclusions by objective sales numbers. This is another pesimistic article saying that games developed by single individuals get 20 downloads a day. Can I kindly ask to clarify from business viewpoint whether average developers publishing games and software on AppStore can cover their living expenses, even, whether they can become profitable? Is it achievable to generate revenues of 50.000 USD yearly on AppStore for a single developer? I would like to stay as realistic as possible. Despite the question might look subjective, a good business man will be able to esitmate chances for profitability and prosperity within AppStore.

  • SQL SERVER – Right Aligning Numerics in SQL Server Management Studio (SSMS)

    - by pinaldave
    SQL Server Management Studio is my most favorite tool and the comfort it provides to user is sometime very amazing. Recently I was retrieving numeric data in SSMS and I found it is very difficult to read them as they were all right aligned. Please pay attention to following image, you will notice that it is not easier to read the digits as we are used to read the numbers which are right aligned. I immediately thought before I go for any other tricks I should check the query properties. I right clicked on query properties and I found following option. I checked option Right align numeric values and it just worked fine. Do you have any other similar tricks which do you practice often. I prefer to also include column headers in the result set as it gives me proper perspective of which column I have selected. Sometime little tips like this helps a lot in productivity, I encourage you to share your tips. I will publish it with due credit.

  • Arithmetic Coding Questions

    - by Xophmeister
    I have been reading up on arithmetic coding and, while I understand how it works, all the guides and instructions I've read start with something like: Set up your intervals based upon the frequency of symbols in your data; i.e., more likely symbols get proportionally larger intervals. My main query is, once I have encoded my data, presumably I also need to include this statistical model with the encoding, otherwise the compressed data can't be decoded. Is that correct? I don't see this mentioned anywhere -- the most I've seen is that you need to include the number of iterations (i.e., encoded symbols) -- but unless I'm missing something, this also seems necessary to me. If this is true, that will obviously add an overhead to the final output. At what point does this outweigh the benefits of compression (e.g., say if I'm trying to compress just a few thousand bits)? Will the choice of symbol size also make a significant difference (e.g., if I'm looking at 2-bit words, rather than full octets/whatever)?

  • Recommendation for a platform to teach game development to kids [closed]

    - by Moshe Kravchik
    My 11 years old son decided he want to create a Web game. He does not know much about programming and I never did any game development so I'm not the best teacher of the topic. On one hand I really want him to get into building things and doing his own game sounds perfect. So I'd like to find a way to keep him interested and progressing by himself. This means that I'm looking for a platform that is: 1. Simple for understanding and use, intuitive interface 2. Powerful 3. Good tools, preferrably free 4. Significant community for questions and tips 5. Localization - my son's English is quite poor (native Hebrew). We looked at Alice, but it was too limited in its abilities and isn't really a Web game building platform. HTML/CSS and Javascript - too low level for a kid to keep the interest. What would you recommend?

  • Java performance of StringBuilder append chains

    - by ultimate_guy
    In Java, if I am building a significant number of strings, is there any difference in performance in the following two examples? StringBuilder sb = new StringBuilder(); for (int i = 0; i < largeNumber; i++) { sb.append(var[i]); sb.append('='); sb.append(value[i]); sb.append(','); } or StringBuilder sb = new StringBuilder(); for (int i = 0; i < largeNumber; i++) { sb.append(var[i]).append('=').append(value[i]).append(','); } Thanks!

  • Automatically Snapshoting AWS instances (or other back up strategy)

    - by user1172468
    I just realized that my aws instance count has risen into the double digits. I'm currently backing portions of my folders and dbs and moving them off to a backup instance. What I think I should be doing is taking a snapshot of the instances (automatically) and persisting them on S3 so I have a running 7 day collection of daily backups. There is a question asking the same thing here, however the answers don't go into depth. So the closest answer seems to be: use a cron job to snapshot the instance. So do I run the cron job on the instance itself? or do I have a micro instance to run these snapshots? Could I get an example script or the command for say a linux flavor? what software must I have installed to get this to run? Thanks.

  • Learning MVC for a JSP Resource and ASP.Net WebForms Resource

    - by Lijo
    Statement from a colleque: - "People with ASP.Net WebForms skills should be able to learn it easily as the fundamental concept is same.” Consider two people –one from JSP background and other from ASP.Net WebForms background. Now both need to learn ASP.Net MVC in RAZOR. Do you think the person from ASP.Net Webforms background has significant advantage over the person from JSP background? My feeling is – it is equally difficult for JSP person and ASP.Net Webforms person to learn MVC with RAZOR. What is your take on it? Any statistics that you can provide for this?

  • UI Testing with Visual Studio 2010 Feature Pack 2

    - by Seth P.
    One of the most intriguing items in the recently released Visual Studio 2010 Feature Pack 2 is the ability to create and edit UI tests in Silverlight. Here is an example of a coded UI test. I haven't had much time to use it yet, but for people who have, I am curious as to what your thoughts are. Is this something you have found to be particularly useful? I would like to be able to automate a significant amount of regression testing that we are currently performing manually. In your experience, has it made a major impact on the resources that you would normally have to dedicate to testing? Thanks, Seth

  • DotNetNuke 5.3.1 Version now entering QA.

    With any software product you will occasionally have a release that you wish you could take back. Microsoft had Windows Vista, and Tuesday we had DotNetNuke 5.3.0.

  • Converting a JD Edwards Date to a System.DateTime

    - by Christopher House
    I'm working on moving some data from JD Edwards to a SQL Server database using SSIS and needed to deal with the way in which JDE stores dates.  The format is CYYDDD, where: C = century, 1 for >= 2000 and 0 for < 2000 YY = the last two digits of the year DDD = the number of the day.  Jan 1 = 1, Dec. 31 = 365 (or 366 in a leap year) The .Net base class library has lots of good support for handling dates, but nothing as specific as the JD Edwards format, so I needed to write a bit of code to translate the JDE format to System.DateTime.  The function is below: public static DateTime FromJdeDate(double jdeDate) {   DateTime convertedDate = DateTime.MinValue;   if (jdeDate >= 30001 && jdeDate <= 200000)   {     short yearValue = (short)(jdeDate / 1000d + 1900d);     short dayValue = (short)((jdeDate % 1000) - 1);     convertedDate = DateTime.Parse("01/01/" + yearValue.ToString()).AddDays(dayValue);   }   else   {     throw new ArgumentException("The value provided does not represent a valid JDE date", "jdeDate");   }   return convertedDate; }  I'd love to take credit for this myself, but this is an adaptation of a TSQL UDF that I got from another consultant at the client site.

  • Are there any "traps" in cloning a VirtualBox VM for concurrent use on the same Host/LAN?

    - by fred.bear
    With Ubuntu as the Host, I want to run two similar/identical(?) instances of a VirtualBox Guest on the same Host, or perhaps on another Host which is on the same LAN... I have set up a Guest as a "base" for the two clones. I have exported it as an ovf appliance. I've imported this "base" guest OS back into VirtualBox, with a unique name and .vdk ... and I have started them both on the same Host, and all seems okay, but I do wonder if I have missed some significant point. ...eg. Is the virtual NIC the same? this would throw the LAN into confusion (I think)... and what about UUIDs? I haven't actually tried 2 clones together, yet... only the original and one clone, but I haven't gone beyond a simple startup ...

  • How To: Use Monitoring Rules and Policies

    - by Owen Allen
    One of Ops Center's most useful features is its asset monitoring capability. When you discover an asset - an operating system, say, or a server - a default monitoring policy is applied to it, based on the asset type. This policy contains rules that specify what properties are monitored and what thresholds are considered significant. Ops Center will send a notification if a monitored asset passes one of the specified thresholds. But sometimes you want different assets to be monitored in different ways. For example, you might have a group of mission-critical systems, for which you want to be notified immediately if their file system usage rises above a specific threshold. You can do so by creating a new monitoring policy and applying it to the group. You can also apply monitoring policies to individual assets, and edit them to meet the requirements of your environment. The Tuning Monitoring Rules and Policies How-To walks you through all of these procedures.

  • Outdoor Programming Jobs...

    - by Rodrick Chapman
    Are there any kinds of jobs that require programming (or at least competency) but take place outdoors for a significant portion of the time? As long as I'm fantasizing, an ideal job would involve programming in a high level language like Haskell, F#, or Scala* for, say, 50% of the time and doing something like digging an irrigation trench the rest of the time. My background: I triple majored in mathematics, philosophy, and history (BS/BA) and have been working as a web developer for the past six years. I love hacking but I'm feeling a bit burned out. *I only chose these languages as examples since, ideally, I'd want to work among high caliber people... but it really doesn't matter.

  • What's the most important trait of a programmer desired by peer programmers [closed]

    - by greengit
    Questions here talk about most important programming skills someone is supposed to possess, and, a lot of great answers spring up. The answers and the questioners seem mostly interested on qualities related to getting a better job, nailing some interview, things desired by boss or management, or improving your programming abilities. One thing that often gets blown over is the genuine consideration for what traits peers want. They don't much value things like you're one of those 'gets things done' people for the company, or you never miss a deadline, or your code is least painful to review and debug, or you're team player with fantastic leading abilities. They probably care more if you're helpful, are a refreshing person to talk to, you're fun to program in pair with, everybody wants you to review their code, or something of that nature. I, for one, would care that I come off to my peers as a pleasurable programmer to work with, as much as I care about my impression on my boss or management. Is this really significant, and if yes, what are the most desirable traits peers want from each other.

  • Five Things Learned at the BSR Conference in San Francisco on Nov 2nd-4th

    - by Evelyn Neumayr
    The BSR Conference 2011—“Redefining Leadership”—held from Nov 2nd to Nov 4th in San Francisco, with Oracle as one of the main sponsors, saw senior business executives, civil society representatives, and other experts from around the world gathering to share strategies and insights on the future of sustainability. The general conference sessions kicked off on November 2nd with a plenary address by former U.S. Vice President Al Gore. Other sessions were presented by CEOs of the caliber of Carl Bass (Autodesk), Brian Dunn (Best Buy), Carlos Brito (Anheuser-Busch InBev) and Ofra Strauss (Strauss Group). Here are five key highlights from the conference: 1.      The main leadership challenge is integrating sustainability into core business functions and overcoming short-termism. The “BSR GlobeScan State of Sustainable Business Poll 2011” - a survey of nearly 500 business leaders from 300 member companies - shows that 84% of respondents are optimistic that global businesses will embrace CSR/sustainability as part of their core strategies and operations in the next five years but consider integrating sustainability into their core business functions the key challenge. It is still difficult for many companies that are committed to the sustainability agenda to find investors that understand the long-term implications and as Al Gore said “Many companies are given the signal by the investors that it is the short term results that matter and that is a terribly debilitating force in the market.” 2.      Companies are required to address increasing compliance requirements and transparency in their supply chain, especially in relation with conflict minerals legislation and water management. The Dodd-Frank legislation, OECD guidelines, and the upcoming Securities and Exchange Commission (SEC) rules require companies to monitor upstream the sourcing of tin, tantalum, tungsten, and gold, but given the complexity of this issue companies need to collaborate and partner with peer companies in their industry as well as in other industries to understand how to address conflict minerals in their supply chains. The Institute of Public and Environmental Affairs’ (IPE) China Water Pollution Map enables the public to access thousands of environmental quality, discharge, and infraction records released by various government agencies. Empowered with this information, the public has the opportunity to place greater pressure on polluting companies to comply with environmental standards and create solutions to improve their performance. 3.      A new standard for reporting on supply chain greenhouse gas emissions is available. The New “Scope 3” Supply Chain Greenhouse Gas Inventory Standard, released on October 4th 2011, is the only international greenhouse gas emissions standard that accounts for the full lifecycle of a company’s products. It provides a framework for companies to account for indirect emissions outside of energy use, such as transportation, manufacturing, and distribution, and it incorporates both upstream and downstream impacts of a product. With key investors now listing supplier vulnerability to rising energy prices and disruptions of service as a key concern, greenhouse gas (GHG) management isn’t just for leading companies but a necessity for any business. 4.      Environmental, social, and corporate governance (ESG) reporting is becoming increasingly important to investors and other stakeholders. While European investors have traditionally driven the ESG agenda, U.S. investors are increasingly including ESG data in their analyses. This trend will likely increase as stakeholders continue to demand that an ESG lens be applied to their investments. Investors are increasingly looking to partner on sustainability, as they see the benefits of ESG providing significant returns on investment. 5.      Software companies are offering an increasing variety of solutions to help drive changes and measure performance internally, in supply chains, and across peer companies. The significant challenge is how to integrate different software systems to facilitate decision-making based on a holistic understanding of trade-offs. Jon Chorley, Chief Sustainability Officer and Vice President, Supply Chain Management Product Strategy at Oracle was a panelist in the “Trends in Sustainability Software” session and commented that, “How we think about our business decisions really comes down to how we think about cost. And as long as we don’t assign a cost to things that have an environmental impact or social impact, then we make decisions based on incomplete information. If we could include that in the process that determines ‘Is this product profitable? we would then have a much better decision.” For more information on BSR visit www.brs.org. You can also view highlights of the plenary session at http://www.bsr.org/en/bsr-conference/session-summaries/2011. Oracle is proud to be a sponsor of this BSR conference.
