• Calculating statistics directly from a CSV file

  - by User1

  I have a transaction log file in CSV format that I want use to run statistics. The log has the following fields: date: Time/date stamp salesperson: The username of the person who closed the sale promo: sum total of items in the sale that were promotions. amount: grand total of the sale I'd like to get the following statistics: salesperson: The username of the salesperson being analyzed. minAmount: The smallest grand total of this salesperson's transaction. avgAmount: The mean grand total.. maxAmount: The largest grand total.. minPromo: The smallest promo amount by the salesperson. avgPromo: The mean promo amount... I'm tempted to build a database structure, import this file, write SQL, and pull out the stats. I don't need anything more from this data than these stats. Is there an easier way? I'm hoping some bash script could make this easy.

• Moving from dedicated to shared cpanel - any scripts to do all / some of the install tasks ?

  - by mbbcat

  Hi, I have a few hundred phpld sites to move - each has its own cpanel, ( & the target may have shared cpanel) & I can do a full cpanel backup on the original server, but I don't have whm on the current host - the backups are fairly easy to organize but the installs so far means picking through files & setting up db's & mail etc by hand - I am thinking there ought to be an easier ie scripted way to do the installs or at least some parts - can anyone please suggest something ? I would like to migrate the stats at the same time Thanks M

• Can an appdomain in C# be restricted to one directory?

  - by Caerbanog

  I am developing a plugin host. The plugins should have as little trust as they need, however I want to have the possibility for a plugin to read and write files. Can the AppDomain where the assembly will be loaded be restricted to have access to only one directory for reading and writing? Other options and ways to go about this are also appreciated like for example easy ways to stream file data from the host to the plugin (reading) and from the plugin to the host (writing). If its relevant: I am using the MAF infrastructure for the plugins. http://msdn.microsoft.com/en-us/library/bb384200.aspx

• iphone dev - loading table content asynchronously

  - by Brian

  My app has a navigation controller which push and pop a series of views. One of the tableViews loads .xml file from URL and it takes 4-5 seconds. If I click the back button on the navigation bar, it will only respond after the content of the table finish loading. Is there an easy way to load the content asynchronously so that the app will still respond to my gesture on the navigation bar? p.s. I search this on the Internet and people are talking about multithreading. I don't know a lot about threads so please be more specific. Thanks in advanced =)

• Replace an element name while retaining the attributes with jquery

  - by geckomist

  I'm trying to create a jquery setup where all instances of <i> are changed to <em>. It's easy enough to do with: $("i").each(function(){ $(this).replaceWith($('<em>' + this.innerHTML + '</em>')); }); But what I am having trouble figuring out is how to change all the <i> tags but retain each ones individual attributes. So if I have <i style="background-color: #333;" alt="Example" title="Example">Example Text</i> I would like it to change to <em style="background-color: #333;" alt="Example" title="Example">Example Text</em> Thanks for any help!

• Transform shape built of contour splines to simple polygons

  - by Cheery

  I've dumped glyphs from truetype file so I can play with them. They have shape contours that consist from quadratic bezier curves and lines. I want to output triangles for such shapes so I can visualize them for the user. Traditionally I might use libfreetype or scan-rasterise this kind of contours. But I want to produce extruded 3D meshes from the fonts and make other distortions with them. So, how to polygonise shapes consisting from quadratic bezier curves and lines? There's many contours that form the shape together. Some contours are additive and others are subtractive. The contours are never open. They form a loop. (Actually, I get only contour vertices from ttf glyphs, those vertices define whether they are part of the curve or not. Even though it is easy to decompose these into bezier curves and lines, knowing the data is represented this way may be helpful for polygonizing the contours to triangles)

• allocator with no template

  - by Merni

  Every stl container take an allocator as a second object, template < class T, class Allocator = allocator<T> > class vector; If you write your own class It is possible to use your own allocator. But is it possible to write your own allocator without using templates? For example, writing this function is not easy if you are not allowed to use templates pointer allocate(size_type n, const_pointer = 0) { void* p = std::malloc(n * sizeof(T)); if (!p) throw std::bad_alloc(); return static_cast<pointer>(p); } Because how could you know the size of T?

• Best .NET Solution for Frequently Changed Database

  - by sestocker

  I am currently architecting a small CRUD applicaton. Their database is a huge mess and will be changing frequently over the course of the next 6 months to a year. What would you recommend for my data layer: 1) ORM (if so, which one?) 2) Linq2Sql 3) Stored Procedures 4) Parametrized Queries I really need a solution that will be dynamic enough (both fast and easy) where I can replace tables and add/delete columns frequently. Note: I do not have much experience with ORM (only a little SubSonic) and generally tend to use stored procedures so maybe that would be the way to go. I would love to learn Ling2Sql or NHibernate if either would allow for the situation I've described above.

• Is there a way to ignore Cache errors in Django?

  - by Josh Smeaton

  I've just set our development Django site to use redis for a cache backend and it was all working fine. I brought down redis to see what would happen, and sure enough Django 404's due to cache backend behaviour. Either the Connection was refused, or various other errors. Is there any way to instruct Django to ignore Cache errors, and continue processing the normal way? It seems weird that caching is a performance optimization, but can bring down an entire site if it fails. I tried to write a wrapper around the backend like so: class CacheClass(redis_backend.CacheClass): """ Wraps the desired Cache, and falls back to global_settings default on init failure """ def __init__(self, server, params): try: super(CacheClass, self).__init__(server, params) except Exception: from django.core import cache as _ _.cache = _.get_cache('locmem://') But that won't work, since I'm trying to set the cache type in the call that sets the cache type. It's all a very big mess. So, is there any easy way to swallow cache errors? Or to set the default cache backend on failure?

• Drupal removing javascript from Full HTML link

  - by Jen

  I am new to Drupal and am trying to create a node (let's call it child) that will only really be accessed when clicked on from another node (we'll call it parent). When closing the child window, I want to parent window to refresh. Outside of Drupal, that's easy: <a onclick="window.close(); window.opener.location.reload();" href="#">Click to close this window</a> However, when I type this into the body of a node using Full HTML, it still strips the onclick text from my post. How can I include javascript in the body of a node like this? Is there a special module I need. Thanks!

• Expectation values in MATLAB

  - by Bowler

  I have a 3D data set representing a grid of photosensors which unfortunately were not steady during use. I have estimated the pdf for the motion of the detector and I want to find the expectation value for each sensor. As I don't want to reflect my pdf (i.e. I want f(t) not f(t-tau)) I don't think I can use the matlab convolve function. Is there a function that will do what I want. I guess f I've found movavg but it seems to do something else. Also, as I'm faily new to matlab, from C, I tend to use for loops which I'm aware is not the way to use Matlab. Is there an easy way to convert my 1-D pdf to a 3D matrix that will only operate in one axis (z in this case). Something like repmat(i, j, pdf)

• Data Validation for Random varying Phone Numbers

  - by baron

  I am storing phone numbers of varying lengths in my WPF (C#, VS 08) App. I store them as strings. My question is about my method AddNewPhoneNo(string phoneNo). In this method, I use Int.TryParse to validate the incoming number (i.e. not null, is numeric...). I've since realized this is probably not the best way to do this, because then I am limited to a number which is ± 2147483647. Definetly this is not always the case with phone numbers. What is a good, easy way to validate phone numbers? I guess the basic rules would be as follows: All numeric All positive Upto 25 chars (could be more, but this will to do for time being) Can't thing if theres any more rules at the moment, that's probably it.

• escaping query string with special characters with python

  - by that_guy

  I got some pretty messy urls that i got via scraping here, problem is that they contain spaces or other special characters in the path and query string, here is some example http://www.example.com/some path/to the/file.html http://www.example.com/some path/?file=path to/file name.png&name=name.me so, is there an easy and robust way to escape the urls so that i can pass them to urlopen? i tried urlib.quote, but it seems to escape the '?', '&', and '=' in the query string as well, and it seems to escape the protocol as well, currently, what i am trying to do is use regex to separate the protocol, path name, and query string and escape them separately, but there are cases where they arent separated properly any advice is appreciated

• Java, How to Instance HttpCookie from a String, any convenient ways?

  - by user435657

  Hi all, I have got a cookie string from HTTP response header like the following line: name=value; path=/; domain=.g.cn; expire=... I can parse the above line to key-value pairs, and, also it's easy to set the name and value to HttpCookie instance as this pair comes the first. But how to set the other pairs since I don't know which set-method corresponds to the name of the next name-value pair. Traverse all possible keys a cookie may contian and call the matched set-method, like below snippet? if (key.equalsIgnoreCase("path")) cookie.setPath(value); else if (key.equalsIgnoreCase("domain")) cookie.setDomain(value); That's foolish, any convenient ways? Thanks in advance.

• lexers / parsers for (un) structured text documents

  - by wilson32

  There are lots of parsers and lexers for scripts (i.e. structured computer languages). But I'm looking for one which can break a (almost) non-structured text document into larger sections e.g. chapters, paragraphs, etc. It's relatively easy for a person to identify them: where the Table of Contents, acknowledgements, or where the main body starts and it is possible to build rule based systems to identify some of these (such as paragraphs). I don't expect it to be perfect, but does any one know of such a broad 'block based' lexer / parser? Or could you point me in the direction of literature which may help?

• More elegant way to initialize list of duplicated items in Python

  - by Claudiu

  If I want a list initialized to 5 zeroes, that's very nice and easy: [0] * 5 However if I change my code to put a more complicated data structure, like a list of zeroes: [[0]] * 5 will not work as intended, since it'll be 10 copies of the same list. I have to do: [[0] for i in xrange(5)] that feels bulky and uses a variable so sometimes I even do: [[0] for _ in " "] But then if i want a list of lists of zeros it gets uglier: [[[0] for _ in " "] for _ in " "] all this instead of what I want to do: [[[0]]*5]*5 Has anyone found an elegant way to deal with this "problem"?

• How can I catch connection requests in my framework?

  - by Falx

  I'm building a framework (OSGi-like) where other parties can program a bundle for. But I want my framework to manage the QoS of the connection-requests that the other parties will do. The easy solution would be to ask them to use (or enforce them to use - although I don't know how) a specific ConnectionRequest bundle of the framework. The problem with this approach is that they wouldn't be able to use any of their own preferred libraries that is counting on the standard Java libraries to make a connection(request). So I wondered if there is a way in Java to catch all the requested connections, so I can add some code about my QoS handling, before its is sent of to the underlaying layer?

• C++: Platform indepentend game lib?

  - by Martijn Courteaux

  Hi, I want to write a serious 2D game, and it would be nice if I have a version for Linux and one for Windows (and eventually OSX). Java is fantastic because of its platform independent. But Java is to slow to write a serious game. So, I thought to write it in C++. But C++ isn't very cross-platform friendly. I can find game libraries for Windows and libraries for Linux, but I'm searching one that I can use for both, by recompiling the source on a Windows platform and on a Linux platform. Are there engines for this or is this idea irrelevant? Isn't it that easy (recompiling)? Any advice and information about C++ libraries would be very very very appreciated!

• What's the best approach to printing/reporting from WPF?

  - by Matt Hamilton

  I have an upcoming project which will have to be able to print simple reports from its data. It'll be WPF-based, and I'm wondering which way to go. I know that WPF introduces its own printing technology (based on XPS) which looks quite easy to use. However, part of me wonders whether it would just be easier to use the ReportViewer control and embed it in a Windows Forms host control, since that will give users the ability to export to a variety of formats as well as print. Has anyone had any experience with printing/reporting from WPF? Which direction would you recommend?

• Get only Excel column names in C#

  - by Newbie

  Is there any easy way apart from ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source="+fileName+";Extended Properties='Excel 8.0;HDR=YES;IMEX=1'"; using (objConn = new OleDbConnection(ConnectionString)) { objConn.Open(); Logger.Info("Reading the file "+fileName+"...."); objCmdSelect = new OleDbCommand("SELECT * FROM [" + sheetName + "$] WHERE 0 = 1", objConn); objAdapter = new OleDbDataAdapter(); objAdapter.SelectCommand = objCmdSelect; objDataset = new DataSet(); Logger.Info("Filling the dataset...."); objAdapter.Fill(objDataset, fileName); Logger.Info("Returning the dataset...."); return objDataset; } and then looping the datatables for getting the excel column names given a filename and sheet name? Using C#(and no interop services) Thanks

• How to execute unknown functions from dynamic load libraries?

  - by activenightly

  It's easy to load functions from dynamic libraries when you know this function in design time. just do something like this: int (*fn)(int); l0 = dlopen("./libfoo.so", RTLD_LAZY); if (!l0) { fprintf(stderr, "l0 %s\n", dlerror()); return 1; } fn = (int (*)(int))dlsym(l0, "foo"); if ((error = dlerror()) != NULL) { fprintf(stderr, "fn:%s\n", error); return 1; } x=(*fn)(y); ... How to execute library function when it's unknown in design time? In runtime you have a function name and array of arguments pointers and array of arguments sizes: char* fn_name="foo"; int foo_argc; void* foo_argv[]; int foo_argv_size[]; In scripting language it's a piece a cake task, but how to implement this nicely in c++?

• Quick to develop web app in Java

  - by Mike Q

  Hi all, I need to develop a basic web app very quickly (1 week) for a demo. My requirements are Java (I need to make use of existing Java libraries to access the relevant data) 2 screens One for static data view, maybe some search parameters Other for basic form entry No fancy AJAX required Ideally easy for a web designer to come in and tart it up as necessary, without having to rewrite everything My first stop was going to be to checkout Wicket as I've heard good things about it. I don't have the time right now to dive into anything heavy, which probably writes off JSF in my mind (I played with JSF1, steep learning curve which I've now slid back down). I'm happy to treat the result as throwaway so if there's a framework which starts of well but then doesn't scale up to bigger projects, that would be ok. Any suggestions appreciated on frameworks/approach.

• Any dynamic database frontend tool from which you can update directly?

  - by Enjoy coding

  Hi Gurus, This is with reference to this question where I got one tabular report format. I need to update the user entered values correctly back to the same table rows. I am in the process of doing this by using general form post data methods by using some logics which I think will not be easy to maintain. So, just out of curiosity, Is there a front end creator javascript libraries or frameworks which can create the front end for any query's resultset and updates the corresponding rows when the user updates them from front end. This need not have all the full functionality, any one usable, customizable thing will reduce the code maintenance problems. I have googled for some javascript libraris for this but not able to get which will be suitable. Please suggest any useful tools. My environment is Mysql, PHP, JQuery, XAMPP server on Windows. Is JQuery provides one. Thanks in advance.

• ASP.NET Session StateServer - is it possible to extract info about current sessions?

  - by Moe Sisko

  I'm looking into changing the ASP.NET session state mode of our application from SQLServer to StateServer (for performance reasons). In SQLServer mode, it is easy to extract information about the current sessions by querying SQL Server tables like ASPStateTempSessions. e.g. things like when each session was created, when it is due to expire, etc. You could even query the session state blob data to extract further application specific info (e.g. like the UserID, if it was saved in session state). This info was useful for administrators. Just wondering if anyone has managed to do something similar for StateServer mode.
