  • Set an Excel cell's color based on multiple other cells' colors

    - by Lord Torgamus
    I have an Excel 2007 spreadsheet for a list of products and a bunch of factors to rate each one on, and I'm using Conditional Formatting to set the color of the cells in the individual attribute columns. It looks something like this: I want to fill in the rating column for each item with a color, based on the color ratings of its individual attributes. Examples of ways to determine this: the color of the category in which the item scored worst the statistical mode of the category colors the average of the category ratings, where each color is assigned a numerical value How can I implement any or all of the above rules? (I'm really just asking for a quick overview of the relevant Excel feature; I don't need step-by-step instructions for each rule.)

  • What's the advantage of using a bash script for cron jobs?

    - by AlxVallejo
    From my understanding you can write your crons by editing crontab -e I've found several sources that instead refer to a bash script in the cron job, rather than writing a job line for line. Is the only benefit that you can consolidate many tasks into one cron job using a bash script? Additional question for a newbie: Editing crontab -e refers to one file correct? I've noticed that if I open crontab -e and close without editing, when I open the file again there is a different numerical extension such as: "/tmp/crontab.XXXXk1DEaM" 0L, 0C I though the crontab is stored in /var/spool/cron or /etc/crontab ?? Why would it store the cron in the tmp folder?

  • Asterisk Register username with special character like "@"

    - by Najibul Huq
    I am using a SIP provider that has provided me with a username like: [email protected] (Note this is only the username part) And has a numerical password. My Register string looks something like this: [email protected]:[email protected] But this is not working, as asterisk is only sending the first part +112223344 before the first @. My provider is adamant about having the full form of it. This is the first time I am facing this issue that is quite unusual for me. Please help.

  • Clone/mirror a textbox in a PDF form

    - by Tim Pietzcker
    I've got a PDF form in Acrobat X Pro where users can enter their name in a textbox on the first page. I would like the contents of that box to be cloned/mirrored in another box on the second page of the same form: However, in the Properties dialog of the second textbox, I can't find a way to reference the first one. I do have options to calculate numerical values and perform validation etc. etc., but I can't seem to simply have it display the contents of another textbox. Is this not possible in PDF forms, or am I overlooking something obvious?

  • Add Free Windows Live Apps to Your Website or Blog

    - by Matthew Guay
    Would you like to use Hotmail, Office Web Apps, Messenger, and more on your website domain?  Here’s how you can add Windows Live to your website for free. Microsoft offers a popular suite of online communications products including Hotmail and Messenger.  Although Hotmail hasn’t been as popular in recent years as Gmail, it is getting a refresh this summer that might make it an even better email solution.  Additionally, the new Office Web Apps offer great compatibility with Office documents. While Skydrive offers 25Gb of free online file storage for all users, so Windows Live can make a great communications solution for your domain. Note: To signup for Windows Live for your domain, you will need to be able to add info to your WordPress.com blog or change Domain settings manually. Getting Started Open the Windows Live Custom Domains page (Link below) to get started adding Windows Live to your domain.  Your free Windows Live account will let you create up to 500 accounts, so it’s great for teams and groups that want to have customized email addresses in addition to those who just want an email account for their website. Enter your domain or subdomain you want to add to Windows Live in the box, and then select whether you want to setup Hotmail with this or now.  We want to add email to our domain, so select Set up Windows Live Hotmail for my domain and click Continue. You’ll need to sign in with a Windows Live ID to create the account, or choose to create a new Windows Live account associated with your domain.   Sign in with your Windows Live ID…this can be a Hotmail, Live Messenger, XBOX Live, Zune ID, or Microsoft.com account. Or, enter your information to create a new Windows Live ID if you selected the second option. Now, review your settings and make sure everything looks correct.  Click the I Accept button to setup your account.   Your account is now fully setup, but you’ll need to add or edit DNS information on your site.  The steps are slightly different depending if your site is hosted on WordPress.com, on your own server, or hosting service. We’ll show you how to do it on either one. First, though, note the information below this box.  You’ll see settings for your Mail setup…   Security settings…   And Messenger integration.  Make note of the settings, especially the circled ones, as we’ll need them in the next step. Integrate Windows Live with Your WordPress Blog If the domain you added to Windows Live is for your WordPress blog, login to your WordPress dashboard in a separate browser window or tab.  Click the arrow beside Upgrades, and select Domains from the menu. Click the Edit DNS link beside the domain name you’re adding to Windows Live. In the text box on this page, enter the following, replacing Your_info with your code from the Mail Setup box in your Windows Live Dashboard.  Note that this is the blurred section in our screenshots.  It should be a numerical code like 1234567890.pamx1.hotmail.com. MX 10 Your_info.pamx1.hotmail.com. TXT v=spf1 include:hotmail.com ~all CNAME Your_info domains.live.com. Click Save DNS records, and your settings are saved to WordPress.  Note that this will only integrate email with your WordPress account; you cannot integrate Messenger with a domain hosted on WordPress.com. Finally, return to your Windows Live Settings page and click Refresh.  If your settings are correct, you’ll now be ready to use Windows Live on your WordPress.com domain. Integrate Windows Live with Your Own Server If your website is hosted on your own server or hosting account, you’ll need to take a few more steps to add Windows Live to your domain.  This is fairly easy, but the steps may be different depending on your hosting company or registrar.  With some hosts, you may have to contact support to have them add the MX records for you.  Our site’s host uses the popular cPanel for website administration, so here’s how we added the MX Entries through cPanel. Login to your website’s cPanel, and select MX Entry under the Mail section. In the text box on this page, enter the following, replacing Your_info with your code from the Mail Setup box in your Windows Live Dashboard.  Note that this is the blurred section in our screenshots.  It should be a numerical code like 1234567890.pamx1.hotmail.com. MX 10 Your_info.pamx1.hotmail.com. Now, go back to your cPanel home, and select Advanced DNS Zone Editor under Domains. Here, add a TXT record with the following info: Name: yoursite.com. TTL: 3600 TXT Data: v=spf1 include:hotmail.com ~all Click Add Record and your Mail integration data is all configured. To integrate Messenger with your own domain, you’ll have to add an SRV entry to your DNS settings.  cPanel doesn’t have an option for this, so we had to contact our site’s hosting company and they added the entry for us.  Copy all of the information in the Messenger box and send it to your domain support, and they should be able to add this for you.  Alternately, if you don’t want or need Messenger, then you can simply skip this step. Once all of your settings are in place, return to your Windows Live Settings page and click Refresh.  If your settings are correct, you’ll now be ready to use Windows Live on your WordPress.com domain. Create a New Email Account On Your Domain Welcome to your new Windows Live admin page!  Now you can add email accounts so you and anyone else you want can access Hotmail and the other Windows Live apps with your domain.  Click Add to add an account. Enter an account name, which will be the email address of the account, e.g. [email protected].  Then enter the user’s name and a password for the account.  By default this will be a temporary password, and the user will have to change it on first log-in, but if you’re setting up this account for yourself, you can uncheck the box and keep this as your standard password. Now, go to www.mail.live.com, and sign in with your new email address and password.  Remember, your email address is your username previously entered followed by @yourdomain.com. To finish setting up the email account, enter your password, secret question and answer, alternate email, and location information.  Click I accept to finish setting up your new email account. Enter the characters in the Captcha to confirm you’re a human, and click Continue. Your new Hotmail inbox will now load, and you’ll have a welcome email in your inbox.  This works the same as normal Hotmail, except this time, your email address is with your own domain. You can now access any of the Windows Live services from the top-level menu. Here’s an Excel Spreadsheet open in the new Office Web Apps via SkyDrive on our new Windows Live account. If you setup Messenger access previously, you can now sign in to Windows Live Messenger using your new @yourdomain.com account as well. Important Links Accessing your Windows Live accounts is easy.  Simply go to any Windows Live site, such as www.hotmail.com or www.skydrive.com, and sign in with your new Windows Live ID from your domain as normal.  You don’t need a special address to access your account; it works just like the standard public Hotmail accounts. To administer your Windows Live for your domain, go to https://domains.live.com/ and sign in with the Windows Live ID you used to create the account.  Here you can add more users, change settings, and view usage details for the Windows Live accounts on your domain. Conclusion Windows Live is easy to add to your domain, and lets you create up to 500 email address for it.  With the upcoming updates to Hotmail and Office Web Apps coming this summer, this can be a nice way to make your domain even more useful.  And with 500 email accounts, you can easily let your team take advantage of your unique address as well. If you’d rather use Google’s online applications with your domain, check out our article on how to add free Google apps to your website or blog.

  • Box 2d basic questions

    - by philipp
    I am a bit new to box2d and I am developing an game with type and letters. I am using an svg font and generate the box2d bodies direct from the glyphs path definition, using the convex hull of them. I also have an decomposition routine the decomposes this hull if necessary. All this it is more or less working, except that I got some strange errors which definitely are caused by the scale factors. The problem is caused by two factors: first: the world scale of box2d, second: the the precision of curve-approximation of the glyph vectors. So through scaling down the input vertices for box2d, it happens that they become equal caused by numerical precision, what causes errors in box2d. Through scaling the my glyphs a bit up, this goes away. I also goes away if I chose a different world scale factor, but this slows down the whole animation quite much! So if my view port is about 990px * 600px and i want to animate Glyphs in box2d which should have a size from about 50px * 50px up to 300px * 300px, which scale factor of the b2world should i choose? How small should the smallest distance from on vertex to another be, while approximating the glyph vectors? Thanks for help greetings philipp EDIT:: I continued reading the docs of box2d and after rethinking of the units system, which is designed to handle object from 0.1 up to 10 meters, I calculated a scale factor of 75. So Objects 600px width will are 8 meters wide in box2d and even small objects of about 20px width will become 0.26 meters width in box2d. I will go on trying with this values, but if there is somebody out there who could give me a clever advice i would be happy!

  • Mission critical embedded language

    - by Moe
    Maybe the question sounds a bit strange, so i'll explain a the background a little bit. Currently i'm working on a project at y university, which will be a complete on-board software for an satellite. The system is programmed in c++ on top of a real-time operating system. However, some subsystems like the attitude control system and the fault detection and a space simulation are currently only implemented in Matlab/Simulink, to prototype the algorithms efficiently. After their verification, they will be translated into c++. The complete on-board software grew very complex, and only a handful people know the whole system. Furthermore, many of the students haven't program in c++ yet and the manual memory management of c++ makes it even more difficult to write mission critical software. Of course the main system has to be implemented in c++, but i asked myself if it's maybe possible to use an embedded language to implement the subsystem which are currently written in Matlab. This embedded language should feature: static/strong typing and compiler checks to minimize runtime errors small memory usage, and relative fast runtime attitude control algorithms are mainly numerical computations, so a good numeric support would be nice maybe some sort of functional programming feature, matlab/simulink encourage you to use it too I googled a bit, but only found Lua. It looks nice, but i would not use it in mission critical software. Have you ever encountered a situation like this, or do you know any language, which could satisfies the conditions? EDIT: To clarify some things: embedded means it should be able to embed the language into the existing c++ environment. So no compiled languages like Ada or Haskell ;)

  • Using Umbraco&rsquo;s Dropdown Datatype

    - by MightyZot
    In Umbraco, you could consider document types like models and data types as property types for those modes. For example, you may create a document type called “Prices” to represent a page that displays a list of prices. And, then, you might create a document type called “Price Item” to represent the price list items. A property called “Price” could then represent the price of an item. When you create the Price property, you specify the data type, which in this case might be “Number”, indicating that this particular field accepts only numerical values. Consequently, you could also create a drop down list property called “Category”, allowing you to categorize the items in your price list. To add items to the drop down list, you modify the data type definition in the Developer module of the Umbraco administrative utility. Instead of modifying the drop down data type itself, you should first make a copy by right-clicking on the Data Types node and choosing Create. Give your new data type a name in the Create dialog and click the Create button. In the Edit datatype dialog, change “Render control” to “Dropdown list”.  To add your list items, simply enter that value into the textbox next to “Add prevalue” and click Save or press the Enter key. Now that you have a new drop down list data type created, along with assigned list items, you can use it in your document type definitions just like you would the other data types.

  • Teaching myself, as a physicist, to become a better programmer

    - by user787267
    I've always liked physics, and I've always liked coding, so when I got the offer for a PhD position doing numerical physics (details are not relevant, it's mostly parallel programming for a cluster) at a university, it was a no-brainer for me. However, as most physicists, I'm self taught. I don't have broad background knowledge about how to code in an object oriented way, or the name of that specific algorithm that optimizes the search in some kD tree. Since all my work so far has been more concerned about the physics and the scientific results, I undoubtedly have some bad habits - more so because my coding is my own, and not really teamwork. I have mostly used C since it is very straightforward and "what you write is what you get" - no need for fancy abstractions. However, I have recently switched to C++ since I'd like to learn more about the power that comes with abstraction, and it's pretty C-like (syntax-wise at least). How do I teach myself to code in a good, abstract way like a graduate in computer science? I know my code is efficient, but I want it to be elegant as well, and readable. Keep in mind that I don't have time to read several 1000-page tomes about abstract programming. I need to spend time on actual, physics related research (my supervisor would laugh at me if he knew I spent time thinking about how to program elegantly). How do I assess if my work is also good from a programmer's perspective?

  • Solving Big Problems with Oracle R Enterprise, Part I

    - by dbayard
    Abstract: This blog post will show how we used Oracle R Enterprise to tackle a customer’s big calculation problem across a big data set. Overview: Databases are great for managing large amounts of data in a central place with rigorous enterprise-level controls.  R is great for doing advanced computations.  Sometimes you need to do advanced computations on large amounts of data, subject to rigorous enterprise-level concerns.  This blog post shows how Oracle R Enterprise enables R plus the Oracle Database enabled us to do some pretty sophisticated calculations across 1 million accounts (each with many detailed records) in minutes. The problem: A financial services customer of mine has a need to calculate the historical internal rate of return (IRR) for its customers’ portfolios.  This information is needed for customer statements and the online web application.  In the past, they had solved this with a home-grown application that pulled trade and account data out of their data warehouse and ran the calculations.  But this home-grown application was not able to do this fast enough, plus it was a challenge for them to write and maintain the code that did the IRR calculation. IRR – a problem that R is good at solving: Internal Rate of Return is an interesting calculation in that in most real-world scenarios it is impractical to calculate exactly.  Rather, IRR is a calculation where approximation techniques need to be used.  In this blog post, we will discuss calculating the “money weighted rate of return” but in the actual customer proof of concept we used R to calculate both money weighted rate of returns and time weighted rate of returns.  You can learn more about the money weighted rate of returns here: http://www.wikinvest.com/wiki/Money-weighted_return First Steps- Calculating IRR in R We will start with calculating the IRR in standalone/desktop R.  In our second post, we will show how to take this desktop R function, deploy it to an Oracle Database, and make it work at real-world scale.  The first step we did was to get some sample data.  For a historical IRR calculation, you have a balances and cash flows.  In our case, the customer provided us with several accounts worth of sample data in Microsoft Excel.      The above figure shows part of the spreadsheet of sample data.  The data provides balances and cash flows for a sample account (BMV=beginning market value. FLOW=cash flow in/out of account. EMV=ending market value). Once we had the sample spreadsheet, the next step we did was to read the Excel data into R.  This is something that R does well.  R offers multiple ways to work with spreadsheet data.  For instance, one could save the spreadsheet as a .csv file.  In our case, the customer provided a spreadsheet file containing multiple sheets where each sheet provided data for a different sample account.  To handle this easily, we took advantage of the RODBC package which allowed us to read the Excel data sheet-by-sheet without having to create individual .csv files.  We wrote ourselves a little helper function called getsheet() around the RODBC package.  Then we loaded all of the sample accounts into a data.frame called SimpleMWRRData. Writing the IRR function At this point, it was time to write the money weighted rate of return (MWRR) function itself.  The definition of MWRR is easily found on the internet or if you are old school you can look in an investment performance text book.  In the customer proof, we based our calculations off the ones defined in the The Handbook of Investment Performance: A User’s Guide by David Spaulding since this is the reference book used by the customer.  (One of the nice things we found during the course of this proof-of-concept is that by using R to write our IRR functions we could easily incorporate the specific variations and business rules of the customer into the calculation.) The key thing with calculating IRR is the need to solve a complex equation with a numerical approximation technique.  For IRR, you need to find the value of the rate of return (r) that sets the Net Present Value of all the flows in and out of the account to zero.  With R, we solve this by defining our NPV function: where bmv is the beginning market value, cf is a vector of cash flows, t is a vector of time (relative to the beginning), emv is the ending market value, and tend is the ending time. Since solving for r is a one-dimensional optimization problem, we decided to take advantage of R’s optimize method (http://stat.ethz.ch/R-manual/R-patched/library/stats/html/optimize.html). The optimize method can be used to find a minimum or maximum; to find the value of r where our npv function is closest to zero, we wrapped our npv function inside the abs function and asked optimize to find the minimum.  Here is an example of using optimize: where low and high are scalars that indicate the range to search for an answer.   To test this out, we need to set values for bmv, cf, t, emv, tend, low, and high.  We will set low and high to some reasonable defaults. For example, this account had a negative 2.2% money weighted rate of return. Enhancing and Packaging the IRR function With numerical approximation methods like optimize, sometimes you will not be able to find an answer with your initial set of inputs.  To account for this, our approach was to first try to find an answer for r within a narrow range, then if we did not find an answer, try calling optimize() again with a broader range.  See the R help page on optimize()  for more details about the search range and its algorithm. At this point, we can now write a simplified version of our MWRR function.  (Our real-world version is  more sophisticated in that it calculates rate of returns for 5 different time periods [since inception, last quarter, year-to-date, last year, year before last year] in a single invocation.  In our actual customer proof, we also defined time-weighted rate of return calculations.  The beauty of R is that it was very easy to add these enhancements and additional calculations to our IRR package.)To simplify code deployment, we then created a new package of our IRR functions and sample data.  For this blog post, we only need to include our SimpleMWRR function and our SimpleMWRRData sample data.  We created the shell of the package by calling: To turn this package skeleton into something usable, at a minimum you need to edit the SimpleMWRR.Rd and SimpleMWRRData.Rd files in the \man subdirectory.  In those files, you need to at least provide a value for the “title” section. Once that is done, you can change directory to the IRR directory and type at the command-line: The myIRR package for this blog post (which has both SimpleMWRR source and SimpleMWRRData sample data) is downloadable from here: myIRR package Testing the myIRR package Here is an example of testing our IRR function once it was converted to an installable package: Calculating IRR for All the Accounts So far, we have shown how to calculate IRR for a single account.  The real-world issue is how do you calculate IRR for all of the accounts?This is the kind of situation where we can leverage the “Split-Apply-Combine” approach (see http://www.cscs.umich.edu/~crshalizi/weblog/815.html).  Given that our sample data can fit in memory, one easy approach is to use R’s “by” function.  (Other approaches to Split-Apply-Combine such as plyr can also be used.  See http://4dpiecharts.com/2011/12/16/a-quick-primer-on-split-apply-combine-problems/). Here is an example showing the use of “by” to calculate the money weighted rate of return for each account in our sample data set.  Recap and Next Steps At this point, you’ve seen the power of R being used to calculate IRR.  There were several good things: R could easily work with the spreadsheets of sample data we were given R’s optimize() function provided a nice way to solve for IRR- it was both fast and allowed us to avoid having to code our own iterative approximation algorithm R was a convenient language to express the customer-specific variations, business-rules, and exceptions that often occur in real-world calculations- these could be easily added to our IRR functions The Split-Apply-Combine technique can be used to perform calculations of IRR for multiple accounts at once. However, there are several challenges yet to be conquered at this point in our story: The actual data that needs to be used lives in a database, not in a spreadsheet The actual data is much, much bigger- too big to fit into the normal R memory space and too big to want to move across the network The overall process needs to run fast- much faster than a single processor The actual data needs to be kept secured- another reason to not want to move it from the database and across the network And the process of calculating the IRR needs to be integrated together with other database ETL activities, so that IRR’s can be calculated as part of the data warehouse refresh processes In our next blog post in this series, we will show you how Oracle R Enterprise solved these challenges.

  • What can be done against language inertia?

    - by gerrit
    Often, projects use programming language X, but would use programming language Y if they were started from scratch. For example, big numerical models may be written entirely in Fortran. Whereas this might be a reasonable choice for the components that need to run fast (alternative would be C or C++), it might be a poor choice for components that either do not need to run fast (such as things dealing with human input or simple visualisations), or where runtime is not the limiting factor (such as I/O, particularly when from the network). Another example may be when a project is built using a propriety language (such as Matlab; no, FOSS clones are not good enough) and was started at a time when FOSS alternatives were not viable, but ten years later, they are; and it would be beneficial to migrate. However, due to language inertia, a migration does not happen. Code that works should not be touched, porting code is a time-consuming, expensive process, and programmers are familiar in language X but not necessarily in language Y. Still, in the long term, a migration would likely be beneficial. Can anything be done to mitigate the problems associated with language inertia? Are there any notable examples of big projects that have successfully overcome this problem? Or is a project bound to stick forever with the initial choices?

  • Can we use Google Earth images by applying our Unity3D mesh ?

    - by Jake M
    We are developing a commercial app for iOS and Android. The app will display development plans(architectural drawings) in a real world 3D environment. The app will work by creating a Unity3D mesh, applies a google earth image as the texture then draws out 3d lines(architectural drawings) over the Unity Mesh. Question: We are unsure if this is allowed under Google's terms and agreements? See quoted text below. In the bold text below its a little vague whether what we are doing(explained above) is violating their terms and agreements. What do you think? Does anyone know how we contact google to ask them? You may not mass download or use bulk feeds of any Content, including but not limited to extracting numerical latitude or longitude coordinates, geocoding, text-based directions, imagery, visible map data, or Places data (including business listings) for use in other applications. You also may not trace Google Maps or Earth as the basis for tracing your own maps or geographic materials. For full details, please read section 10.3.1 of the Maps/Earth API Terms of Service. Does anyone have any advice/experience dealing with this stuff?

  • I need a decent alternative to c++ [closed]

    - by wxiiir
    I've learned php and c++, i will list the things i liked and didn't liked on each of them, how i decided to learn them in the first place and why i feel the need to learn a decent alternative to c++, i'm not a professional programmer and only do projects for myself. PHP - Decided to learn because i wanted to build a dynamic website, that i did and turned out very good, i even coded a 'not so basic' search engine for it that would display the results 'google style' and really fast, pretty cool stuff. PROS - Pretty consistent syntax for all stuff (minor caveats), great functionality, a joy for me to code in it (it seems to 'know' what i want it to do and just does it) CONS - Painfully slow for number crunching (which takes me to c++ that i only learned because i wanted to do some number crunching and it had to be screaming fast) C++ - Learned because number crunching was so slow in php and manipulating large amounts of data was very difficult, i thought, it's popular programming language and all, and tests show that it's fast, the basic stuff resemble php so it shouldn't be hard to pick up PROS - It can be used to virtually anything, very very fast CONS - Although fun to code at the start, if i need to do something out of the ordinary, memory allocation routines, pointer stuff, stack sizes etc... will get me tired really quick, syntax is a bit inconsistent some times (more caveats) I guess that from what i wrote you guys will understand what i'm looking for, there are thousands of languages out there, it's likely that one of them will suit my needs, i've been seeing stuff today and a friend of mine that is a professional programmer tried OCaml and Fortran and said that both are fast for numerical stuff, i've been inclined to test Fortran, but i need some more input because i want to have some other good 'candidates' to choose from, for example the python syntax seemed great to me, but then i found out from some tests that it was a lot slower than c++ and i simply don't want to twiddle my thumbs all day.

  • Referencing variables in a structure / C++

    - by user1628622
    Below, I provided a minimal example of code I created. I managed to get this code working, but I'm not sure if the practice being employed is sound. In essence, what I am trying to do is have the 'Parameter' class reference select elements in the 'States' class, so variables in States can be changed via Parameters. Questions I have: is the approach taken OK? If not, is there a better way to achieve what I am aiming for? Example code: struct VAR_TYPE{ public: bool is_fixed; // If is_fixed = true, then variable is a parameter double value; // Numerical value std::string name; // Description of variable (to identify it by name) }; struct NODE{ public: VAR_TYPE X, Y, Z; /* VAR_TYPE is a structure of primitive types */ }; class States{ private: std::vector <NODE_ptr> node; // shared ptr to struct NODE std::vector <PROP_DICTIONARY_ptr> property; // CAN NOT be part of Parameter std::vector <ELEMENT_ptr> element; // CAN NOT be part of Parameter public: /* ect */ void set_X_reference ( Parameter &T , int i ) { T.push_var( &node[i]->X ); } void set_Y_reference ( Parameter &T , int i ) { T.push_var( &node[i]->Y ); } void set_Z_reference ( Parameter &T , int i ) { T.push_var( &node[i]->Z ); } bool get_node_bool_X( int i ) { return node[i]->X.is_fixed; } // repeat for Y and Z }; class Parameter{ private: std::vector <VAR_TYPE*> var; public: /* ect */ }; int main(){ States S; Parameter P; /* Here I initialize and set S, and do other stuff */ // Now I assign components in States to Parameters for(int n=0 ; n<S.size_of_nodes() ; n++ ){ if ( S.get_node_bool_X(n)==true ){ S.set_X_reference ( P , n ); }; // repeat if statement for Y and Z }; /* Now P points selected to data in S, and I can * modify the contents of S through P */ return 0; }; Update The reason this issue cropped up is I am working with Fortran legacy code. To sum up this Fotran code - it's a numerical simulation of a flight vehicle. This code has a fairly rigid procedural framework one must work within, which comes with a pre-defined list of allowable Fortran types. The Fortran glue code can create an instance of a C++ object (in actuality, a reference from the perspective of Fortran), but is not aware what is contained in it (other means are used to extract C++ data into Fortran). The problem that I encountered is when a C++ module is dynamically linked to the Fortran glue code, C++ objects have to be initialized each instance the C++ code is called. This happens by virtue of how the Fortran template is defined. To avoid this cycle of re-initializing objects, I plan to use 'State' as a container class. The Fortran code allows a 'State' object, which has an arbitrary definition; but I plan to use it to harness all relevant information about the model. The idea is to use the Parameters class (which is exposed and updated by the Fortran code) to update variables in States.

    Great Indian Developer Summit 2010 – India's Biggest Polyglot Conference and Workshops for IT Software Professionals Bangalore, April 9, 2010: The GIDS.Web Conference and Workshops has announced the complete program of over 30 sessions on how browser and rich web technologies such as AJAX, DHTML, Mashups, Web 2.0, Enterprise 2.0 technologies, and Rich UI technologies are making money and gaining market-share for some of the leading businesses in the world. The GIDS.Web track at Great Indian Developer Summit takes place 21 and 23 April 2010, at the Indian Institute of Science in Bangalore. As one of the longest running independent developer conferences in India, GIDS.Web at the Great Indian Developer Summit 2010 is uniquely positioned to provide a blend of practical, pragmatic and immediately applicable knowledge and a glimpse of the future of technology. During 21 and 23 April 2010, GIDS.Web offers a multi-track conference, workshops, expo show floor, and networking opportunities. The first keynote at GIDS.Web is led by the leading Java EE and Ajax developer, speaker, and author Marty Hall. The best of India's Java and RIA programmers have learnt the subject from Marty's seminal books Core Servlets and JavaServer Pages (first and second editions), More Servlets and JavaServer Pages, and Core Web Programming (first and second editions) from Prentice Hall and Sun Microsystems Press. Marty's keynote address is a comparison of approaches to building rich Internet applications with Ajax. Marty says Ajax development is difficult, and there are several fundamentally different strategies to building Ajaxified Web applications. The keynote address will survey the three most important of these approaches: using an Ajax-enabled JavaScript library such as jQuery, Prototype, Scriptaculous, Dojo, or Ext/JS; using a Web framework such as JSF 2.0 or Struts 2 that has integrated Ajax support; using the Google Web Toolkit (GWT) to build "pure Java" Ajax applications. The talk will compare and contrast these three approaches, discussing the types of applications that fit best for each option. Over the course of the summit Marty will conduct several more sessions on "Choosing an Ajax/JavaScript Toolkit: A Comparison of the Most Popular JavaScript Libraries", "Pure Java Ajax: An Overview of GWT 2.0", "Integrated Ajax Support in JSF 2.0" and "Ajax Support in the Prototype JavaScript Library". The second keynote by the head of Adobe's Flash initiative in India, Ramesh Srinivasaraghavan, explores the state of art in web application development and identify trends that could transform the way we create and use web applications. The talk explains how the Adobe Flash Platform has fuelled this revolution with an integrated set of technologies for delivering the most compelling applications, content and video to the widest possible audience.

  • Any rerefence of CPU world statistics?

    - by Áxel Costas Pena
    I am looking for any referencee about computer power statistics across the world. My main interest is about real computing capabilities, so I'd prefer information about real processor power, and even best if it includes also other critical hardware statistics, like RAM memory, but if it isn't possible, maybe statistics about brand/model distribution will be also useful. I've Googled for some minutes and I've found nothing related.

  • How can I run the same Linux Installation on my hardware and in a virtual machine?

    - by LithMaster
    I've started some development that requires Linux (I'm currently on Ubuntu, but I may switch to Debian), but I still use Windows 7 for my day-to-day computing. I have already tried a dual-boot setup, but I've found that it is too cumbersome to switch between Linux and Windows. I'm wondering if it's possible to setup an installation of Linux (again, Ubuntu or Debian) on a partition of my hard drive that I can also run from Windows in a virtualized environment.

  • Why not switch to Linux?

    - by Ehtyar
    I've had the desire to move to Linux for desktop computing for some time, as the OS just suits me, I think, better than Windows. I've not yet moved from Windows for a few reasons: It's used in my workplace. I have an extensive application base that does whatever I need (and they're all on a portable hdd) I am familiar developing software on Windows. So, what about Linux keeps you from moving to it, or what does your current desktop OS offer that Linux does not?
