• how to aggregate this data in R

  - by stevejb

  Hello, I have a data frame in R with the following structure. > testData date exch.code comm.code oi 1 1997-12-30 CBT 1 468710 2 1997-12-23 CBT 1 457165 3 1997-12-19 CBT 1 461520 4 1997-12-16 CBT 1 444190 5 1997-12-09 CBT 1 446190 6 1997-12-02 CBT 1 443085 .... 77827 2004-10-26 NYME 967 10038 77828 2004-10-19 NYME 967 9910 77829 2004-10-12 NYME 967 10195 77830 2004-09-28 NYME 967 9970 77831 2004-08-31 NYME 967 9155 77832 2004-08-24 NYME 967 8655 What I want to do is produce a table the shows for a given date and commodity the total oi across every exchange code. So, the rows would be made up of unique(testData$date) and the columns would be unique(testData$comm.code) and each cell would be the total oi over all exch.codes on a given day. Thanks,

• Storage for large gridded datasets

  - by nullglob

  I am looking for a good storage format for large, gridded datasets. The application is meteorology, and we would prefer a format that is common within this field (to help exchange data with others). I don't need to deal with special data structures, and there should be a Fortran API. I am currently considering HDF5, GRIB2 and NetCDF4. How do these formats compare in terms of data compression? What are their main limitations? How steep is the learning curve? Are there any other storage formats worth investigating? I have not found a great deal of material outlining the differences and pros/cons of these formats (there is one relevant SO thread, and a presentation comparing GRIB and NetCDF).

• Interesting Row_Number() bug

  - by Joel Coehoorn

  I was playing with the Stack Exchange Data Explorer and ran this query: http://odata.stackexchange.com/stackoverflow/q/2828/rising-stars-top-50-users-ordered-on-rep-per-day Notice down in the results, rows 11 and 12 have the same value and so are mis-numbered, even though the row_number() function takes the same order by parameter as the query. I know the correct fix here is to specify an additional tie-breaker column in the order by clauses, but I'm more curious as to why/how the row_number() function returned different results on the same data? If it makes a difference anywhere, this runs on Azure.

• Send mail from a Windows script

  - by Jörgen Lundberg

  I would like to send mail from a script on a Windows Server 2003 Standard Edition. I think the server setup is pretty much out of the box. The mail server is an Exchange one, and when you're on the internal network you can use plain old SMTP. I have done it from my machine with Perl, but unfortunately Perl is not available on the server. Is there an easy way of doing this from a .bat-file or any other way that doesn't require installing some additional software? Edit: Thanks for the quick replies. The "blat" thingie would probably work fine but with wscript I don't have to use a separate binary. I didn't see PhiLho's post the first time I edited and selected an answer. No need for me to duplicate the code here. Just save the script to a file, say sendmail.vbs, and then call it from the command prompt like so: wscript sendmail.vbs

• How do you encrypt data between client and server running in Flash and Java?

  - by ArmlessJohn

  We have a multiclient system where the client is written in Flash and the server is written in Java. Currently, communication is done in Flash by usage of flash.net.Socket and the protocol is written in JSON. The server uses a custom port to receive connections and then proceed to talk with each client. As expected, data is sent and received on both fronts as raw bytes, which are then decoded as needed. We would like to encrypt the communication between clients and server. I have some basic understanding about public/private key encryption, but I do not know what is the best way to exchange keys or what libraries are available (on both languages) to do this. What would be the best strategy to attack this problem and where should I start looking for libraries/methods to implement this encryption?

• How do you get Windows Mobile Device Center to detect a Windows Phone 7 Series emulator?

  - by sweeney

  Hello, I'm running some tests and need to be able to get Windows Phone 7 Series emulator synced with an exchange account or local Outlook account via the Device Center. I'm using the unlocked version of the emulator so that i actually have a reasonable set of software on the phone to work with. When the emulator launches i expect the Device Center to detect it and start syncing (or prompt me for settings). This does not happen. I've tried adjusting the Connection Settings (COM2 and DMA) in the Device Center with no luck. Is this possible? Has anyone done it? Thanks in advance!

• Store previous search criteria using ASP.NET

  - by thatuxguy

  I have created a web application which returns a list of products. On this page it allows users to search for a range of different search criteria. Once a user searches and the results are returned to the table on the page a user can then edit a product. However upon returning to the product listing page the page just reloads, and shows all products again. I would like to know what the best way would be to keep the search results, and upon returning to the search page it keeps the previous criteria. I have found a few posts on stack exchange - Best way to store previous search criteria in ASP.NET - is probaly one of the better ones. Does any one know how i could go about keeping the search criteria, so when a user returns to the search page, the previous search criteria and results stay the same. Many thanks.

• What is the best way to reject messages with the same body in AMQ queue?

  - by archer

  I have a single AMQ queue that receives simple messages with string body. Consider I'm sending CLSIDs as message bodies. CLSIDs could be not unique, but I'd like to reject all messages with not unique bodies and keep only single instance of such messages in the queue. Is there any simple way to do it? Currently I'm using a workaround. Messages from the queue are consumed by some processor that tries to insert bodies into a simple DB table with UNIQUE constraint applied to message_body field. If processor inserts the messages succesfuly - it's assigned to exchange.out.body and sent to other queue. If ConstraintViolationException is thrown - nothing is resent to other queue. I would like to know does AMQ support something similar out of the box?

• What notes should I be taking, if any, at the beginning of a project?

  - by Justin R.

  I was recently asked by a Team Leader (not mine) if I would be willing to undertake a programming project. The members of his team are currently pre-occupied with other more important projects. I graduated college two years ago, and up until now programming has only been a hobby of mine. Recently I decided that I would like to pursue a career in software development. I accepted his offer so that I can gain some real-world experience and start building a portfolio. In about an hour I'm scheduled to meet with the Team Leader to discuss the details of what he needs. From a short e-mail exchange with him, I know that the base project is to update an existing ASP.NET form—but I also think there's more to it than that. Considering that I'd like to eventually put this project in a portfolio, what kinds of notes should I take at the meeting?

• What technology to use for a RIA

  - by user297159

  I have to develop a online business software solution (similar to ERP) for a company to manage the information exchange for internal use and with external partners. It should be online. What technology should I use, I have checked framewroks like: Flex, Silverlight, Google/GWT, sencha (ExtJS), jQuery, DoJo, Telereik, Infrajistics and others similar. But they seam to be very low level programming. May be this is advantage for other projects, where you need more flexibility, but this project is stright forward. I need something more focused on business software (tables, forms, processes) where and eventually more efficient with less coding, or something I can save time. Is force.com an option? But I can not install this on the customer's servers... Do you have any ideas for me for a web based framework focused on business applications?

• Instant file sharing between users in PHP

  - by Skyfe

  Hi there, Working on a rather complex system in which users can directly exchange files with eachother from the website. However is any of these things possible: EITHER * Have another user download a file which is still being uploaded by another user ( in progress ) OR * Make a user automaticly ( instant ) download a file from another users PC through our website OR * Make a user automaticly (instant) download a file from our server ( so it's directly downloaded to the users pc and the progress shown on our website of the download progress, without the normal internet explorer dialog downloading the file or firefox ). Thank you very much in advanced, Best Regards, Webcodez.net. UPDATE: an example would be MSN's file sharing but then through a website instead of application.

• Don't panic - there is time!

  - by ripper234

  If you're thinking of moving to Shapado right this instance, take a breath. Yes, I think it's the right move in the long run (be it three months or a year). However, take into consideration that the platform is still not ready. It has bugs and feature-requests that should be fixed. Until they are, you are better off staying with Stack Exchange as long as you can. Of course, it is in your best interest to participate heavily in the 'meta discussion' that takes place at Shapado.com and vote on the features and bug fixes that you want.

• Execute a method less times possible - PHP

  - by serhio

  I have a site in multiple languages. I have a method that returns me the today currencies in a array. I display that currencies in a table then. // --- en/index.php <?php include_once "../exchangeRates.php"; $currencies = ReadExchangeRates(); // --- fr/index.php <?php include_once "../exchangeRates.php"; $currencies = ReadExchangeRates(); ... // somewhere in the page <td><?php echo $currencies["eur"]["today"]; ?></td> So, every time I load, en/ or fr/ or other language, I request the exchange rates from a external site. Can I optimize this behavior (reading once per day or session)? maybe to store a global variable and check the update date?

• Getting a list of all phone contacts?

  - by pcm2a

  Simple enough question. I need to know the best way to get the same list of contacts that show up when a user presses the Contacts button. You would think something like this would work: //For Contacts Intent pickIntent = new Intent(Intent.ACTION_PICK, People.CONTENT_URI); this.startActivityForResult(pickIntent, RESULT); //For Phones Intent pickIntent = new Intent(Intent.ACTION_PICK, Phones.CONTENT_URI); this.startActivityForResult(pickIntent, RESULT); The problem is that does not include secondary google accounts or Exchange contacts. By secondary accounts, in Android you can add additional gmail accounts to have the mail/contacts synced. The above intent will not list those additional contacts. I am also told that on the HTC Desire you can add contacts to the phone that do not get synced up to Google. These contacts also do not show up. So how do I get a real list of contacts so I can create my own list activity that works properly where the Google intent does not.

• How to deploy and secure an ASP.NET web app to be available to internal and outside users?

  - by Swoop

  My company has several web applications written in ASP.NET. We need to make these applications available to Intranet users as well as authenticated external users. Most of the features are the same for the two groups, though there are some extra features available to the Internal users. The two different sets of users would use a slightly different security setup... our internal people will be authenticated using LDAP against Exchange, whereas the external users will have accounts in SQL Server. What is the best approach for deploying our web apps? Should we deploy 2 copies to different servers, one configured for an Intranet and one for outside users? Or is there a better way to share the code between the 2 servers, yet have the flexibility to use different web.config settings for security??

• How to make a Windows Mobile based WinForms .Net application easily changeable?

  - by Arthur

  I need to build a Win Mobile WinForms .Net application that once developed will be easy to morph or adjust to new user requirements quickly (including changes in GUI). The main objective is to minimize the development time (development to production roll-out effort). Also, a nice thing to have is to be able to test it in an automated way. The application must be able to: 1) Persist state (may use a local database); 2) Sync data across (via Radio or WiFi); 3) Exchange info with a desktop PC or a central server;

• Convert a string representation of a hex dump to a byte array using Java?

  - by ravigad

  I am looking for a way to convert a long string (from a dump), that represents hex values into a byte array. I couldn't have phrased it better than the person that posted the same question here: http://www.experts-exchange.com/Programming/Programming_Languages/Java/Q_21062554.html But to keep it original, I'll phrase it my own way: suppose I have a string "00A0BF" that I would like interpreted as the byte[] {0x00,0xA0,0xBf} what should I do? I am a Java novice and ended up using BigInteger and watching out for leading hex zeros. But I think it is ugly and I am sure I am missing something simple...

• Android – multiple custom versions of the same app

  - by Ulrich Scheller

  Whats the best way to deploy several customized versions of a Android application? Currently I have a script to exchange the resource folder for getting a customized version of my app. It works great, but all custom versions still have the same package name in the AndroidManifest.xml. Therefore it is not possible to install two customized versions of the app at the same time. This is one solution for this problem, but that has to be done by hand Can you think of a more easy solution, or how this could be built into a skript? (btw: it is not for a porn/spam/whatever app, not even a paid one)

• Background task in mobile phone to access a secure element and a web server

  - by Splryxx

  Is it possible in a GSM mobile phone OS (e.g. Android, Win Mo, Symbian, etc.) to have some kind of background task or application able to exchange data at the same time with a web server and a secure element of the mobile? The purpose if for the web server to be able to push APDUs to the secure element (an retrieve response APDUs) without activating the IHM of the mobile. NB: I know that this is possible when the secure element is the one managing the GSM baseband, for example using BIP as described in Ulysse specifications. My question is only when using another secure element (e.g. Java Card in a microSD).

• IDL-like parser that turns a document definition into powerful classes?

  - by paniq

  I am looking for an IDL-like (or whatever) translator which turns a DOM- or JSON-like document definition into classes which are accessible from both C++ and Python, within the same application expose document properties as ints, floats, strings, binary blobs and compounds: array, string dict (both nestable) (basically the JSON type feature set) allow changes to be tracked to refresh views of an editing UI provide a change history to enable undo/redo operations can be serialized to and from JSON (can also be some kind of binary format) allow to keep large data chunks on disk, with parts only loaded on demand provide non-blocking thread-safe read/write access to exchange data with realtime threads allow multiple editors in different processes (or even on different machines) to view and modify the document The thing that comes closest so far is the Blender 2.5 DNA/RNA system, but it's not available as a separate library, and badly documented. I'm most of all trying to make sure that such a lib does not exist yet, so I know my time is not wasted when I start to design and write such a thing. It's supposed to provide a great foundation to write editing UI components.

• Reference Paramters in C++: VERY basic example please.

  - by Sagistic

  I am trying to understand how to use reference parameters. There are several examples in my text, however they are too complicated for me to understand why and how to use them. Could anyone give me the MOST basic example of how/why to use one, and perhaps the difference with or without it (what would happen if you didn't attach the '&'). for example, if I've created a function: int doSomething(int& a, int& b), what would be the consequences of not putting in that '&.' I understand that reference variables are used in order to change a formal-reference, which then allows a two-way exchange of parameters. However, that is the extent of my knowledge, and a more concrete example would be of much help. Thank you.

• Using my ISerializable implementation instead of DataContractSerializer

  - by mpm

  My WCF client and server exchange objects whose types are defined on a class library shared by both, the server and the client. These objects implement custom serialization via ISerializable. However, my custom serialization is not being used. DataContractSerializer is being used, instead. How do I force my custom serialization to be used? The reason why I need to use my own serialization is because I do trasfer some big object graphs and my serialization algorithm does a good job in compressing/speeding up things.

• php codeigniter MySQL search query

  - by kalafun

  I want to create a search query on MySQL database that will consist of 5 different strings typed in from user. I want to query 5 different table columns with these strings. When I for example have input fields like: first name, last name, address, post number, city. How should I query the database that I dont always get all the rows. My query is something like this: SELECT user_id, username from users where a like %?% AND b like %?% AND c like %?% AND d like %?% AND e like %?%; When I exchange the AND for OR I always get all the results which makes sense, and when I use AND I get only the exact matches... Is there any function or statement that would help me with this?
