• Custom tag with the logic in JSP (interprets JSPs with the passed parameters)

  - by Romario

  I want to create a custom jsp tag. I want this tag to take a jsp file as a parameter, and in this jsp I want to write the whole logic of the tag. Let's say I want to pass a collection to a tag and then I would write code in jsp to iterate the collection and display it in . Why I want to do it - I really hate having out.print() in my code. Is something like this feasible? I remember doing something similar a while ago, I just forgot the details and my search doesn't seem to find relevant info - a link to a good implementation of the would be nice.

• Do you know Best Practise and Design Patterns for Adobe Air/Flex Applications?

  - by Julian

  I'm going to write an application with the Air/Flex-Framework. I'm looking for Best Practise and general Design Patterns for designing software especially in Air/Flex. I have experience with this framework but never had the pleasure to write a piece of software from scratch. For instance: I stumbled across lots of software written in Air/Flex with nearly infinity global vars :-) Most of the software I saw was not object-oriented How can I pack the asynchronous method calls nicely? I'm familiar with general design patterns by gamma. I'm looking more for advise in designing good quality software with Adobe Air/Flex.

• A reasonable way to add attributes to an xml root element in C#.

  - by DrLazer

  The function "WriteStartElement" does not return anything. I find this a little bizzare. So up until now I have been doing it like this. XmlDocument xmlDoc = new XmlDocument(); XmlTextWriter xmlWriter = new XmlTextWriter(m_targetFilePath, System.Text.Encoding.UTF8); xmlWriter.Formatting = Formatting.Indented; xmlWriter.WriteProcessingInstruction("xml", "version='1.0' encoding='UTF-8'"); xmlWriter.WriteStartElement("client"); xmlWriter.Close(); xmlDoc.Load(m_targetFilePath); XmlElement root = xmlDoc.DocumentElement; Saving the doc, then reloading it to get hold of the start element so i can write attributes to it. Does anybody know the correct way of doing this because I'm pretty sure what I'm doing isn't right. I tried to use xmlWriter.AppendChild() but it doesnt seem to write out anything. :(

• unit-testing maven plugins

  - by Don

  Hi, I'm looking for information about how to write unit tests for Maven plugins. Although there's a page on the Maven site about this topic, there's only one example unit test, which does nothing useful. I also found this wiki page, but it hasn't been updated for more than 4 years, so I'm reluctant to invest any faith in it. I checked the book "The Definitive Guide to Maven", but it doesn't even mention the subject. I'd like to write my unit tests in either Groovy or Java, and would appreciate any information about how to do this. Thanks, Don

• programming question about numbers

  - by Syom

  it's a task, on which i think during whole day. i have four integer numbers a, b, c, d, and ineger x[1,40]. i must write a program, which can find the values of {a,b,c,d}, for which one of following equations is true for any (x<=40, x=1) x=a or x=b or x=a+b or x=a+b+c+d or x+a=c+d or x+a+b=c+d or ... x+a+b+c=d or ... it is very difficult to explain what i want to say. maybe the example will be helpful. example: if x=17, by {a=1,b=2,c=5,d=15} i can write x+a+b=c+d whole question is to present any x[1,40] by {a,b,c,d}. hope that you understand what i want to say, and thanks in advance

• PowerShell copy fails without warning

  Howdy, am trying to copy a file from IE cache to somewhere else. This works on w7, but not Vista Ultimate.

• Best approach to get clicked objects from a display list (2D)

  - by Ixx

  I'm implementing a display list to manage my visuals on screen. I want to know which object is clicked. My objects already have z-order variable. With my current knowledge (almost nothing) the only thing which comes to my mind is make a linear search and get all the objects which contains the clicked point. And then select the object with the highest z-order. But I know there are far better approaches. I think it's something with trees (binary search?). - container display objects and search recursively? just don't know where to start looking, for this concrete case. Any hint link or concrete solution is welcome.

• Why is 2^16 a "special" number?

  - by javamonkey79

  OK, I feel stupid asking this - but in Jeff's article: Getting the Interview Phone Screen Right and originally stated in the 5 essential phone screen questions: They shouldn't stare blankly at you when you ask with 2^16 is. It's a special number. They should know it. I've been a developer\software engineer\code monkey\whatever for a little while now, and I don't think I've ever come across this. I mean, I can certainly count binary values do basic operations on them, etc, etc. But I don't see what is "special" about this value.

• Practical Python-based visual programming environment?

  - by Who8MyLunch

  I am looking for a practical visual programming environment based on Python. My primary application is algorithm development for processing remote-sensing imagery. I was initially inspired by LabVIEW from National Instruments, but that is more geared towards laboratory measurements and simulations. I write a lot of prototype code in Python and do a lot of interactive analysis with IPython. Does there exist a visual framework where a "program" is represented by connected nodes which each read data, do some work, and output data to the next node? I would like to use Python to write the code residing in each node. So far the best I've seen is Orange http://www.ailab.si/orange/, but it does not have the ability to start/stop individual nodes.

• ASP Classic Named Parameter in Paramaterized Query: Must declare the scalar variable

  - by My Alter Ego

  I'm trying to write a parameterized query in ASP Classic, and it's starting to feel like i'm beating my head against a wall. I'm getting the following error: Must declare the scalar variable "@something". I would swear that is what the hello line does, but maybe i'm missing something... <% OPTION EXPLICIT %> <!-- #include file="../common/adovbs.inc" --> <% Response.Buffer=false dim conn,connectionString,cmd,sql,rs,parm connectionString = "Provider=SQLOLEDB.1;Integrated Security=SSPI;Data Source=.\sqlexpress;Initial Catalog=stuff" set conn = server.CreateObject("adodb.connection") conn.Open(connectionString) set cmd = server.CreateObject("adodb.command") set cmd.ActiveConnection = conn cmd.CommandType = adCmdText cmd.CommandText = "select @something" cmd.NamedParameters = true cmd.Prepared = true set parm = cmd.CreateParameter("@something",advarchar,adParamInput,255,"Hello") call cmd.Parameters.append(parm) set rs = cmd.Execute if not rs.eof then Response.Write rs(0) end if %>

• Odd optimization problem under MSVC

  - by Goz

  I've seen this blog: http://igoro.com/archive/gallery-of-processor-cache-effects/ The "weirdness" in part 7 is what caught my interest. My first thought was "Thats just C# being weird". Its not I wrote the following C++ code. volatile int* p = (volatile int*)_aligned_malloc( sizeof( int ) * 8, 64 ); memset( (void*)p, 0, sizeof( int ) * 8 ); double dStart = t.GetTime(); for (int i = 0; i < 200000000; i++) { //p[0]++;p[1]++;p[2]++;p[3]++; // Option 1 //p[0]++;p[2]++;p[4]++;p[6]++; // Option 2 p[0]++;p[2]++; // Option 3 } double dTime = t.GetTime() - dStart; The timing I get on my 2.4 Ghz Core 2 Quad go as follows: Option 1 = ~8 cycles per loop. Option 2 = ~4 cycles per loop. Option 3 = ~6 cycles per loop. Now This is confusing. My reasoning behind the difference comes down to the cache write latency (3 cycles) on my chip and an assumption that the cache has a 128-bit write port (This is pure guess work on my part). On that basis in Option 1: It will increment p[0] (1 cycle) then increment p[2] (1 cycle) then it has to wait 1 cycle (for cache) then p[1] (1 cycle) then wait 1 cycle (for cache) then p[3] (1 cycle). Finally 2 cycles for increment and jump (Though its usually implemented as decrement and jump). This gives a total of 8 cycles. In Option 2: It can increment p[0] and p[4] in one cycle then increment p[2] and p[6] in another cycle. Then 2 cycles for subtract and jump. No waits needed on cache. Total 4 cycles. In option 3: It can increment p[0] then has to wait 2 cycles then increment p[2] then subtract and jump. The problem is if you set case 3 to increment p[0] and p[4] it STILL takes 6 cycles (which kinda blows my 128-bit read/write port out of the water). So ... can anyone tell me what the hell is going on here? Why DOES case 3 take longer? Also I'd love to know what I've got wrong in my thinking above, as i obviously have something wrong! Any ideas would be much appreciated! :) It'd also be interesting to see how GCC or any other compiler copes with it as well! Edit: Jerry Coffin's idea gave me some thoughts. I've done some more tests (on a different machine so forgive the change in timings) with and without nops and with different counts of nops case 2 - 0.46 00401ABD jne (401AB0h) 0 nops - 0.68 00401AB7 jne (401AB0h) 1 nop - 0.61 00401AB8 jne (401AB0h) 2 nops - 0.636 00401AB9 jne (401AB0h) 3 nops - 0.632 00401ABA jne (401AB0h) 4 nops - 0.66 00401ABB jne (401AB0h) 5 nops - 0.52 00401ABC jne (401AB0h) 6 nops - 0.46 00401ABD jne (401AB0h) 7 nops - 0.46 00401ABE jne (401AB0h) 8 nops - 0.46 00401ABF jne (401AB0h) 9 nops - 0.55 00401AC0 jne (401AB0h) I've included the jump statetements so you can see that the source and destination are in one cache line. You can also see that we start to get a difference when we are 13 bytes or more apart. Until we hit 16 ... then it all goes wrong. So Jerry isn't right (though his suggestion DOES help a bit), however something IS going on. I'm more and more intrigued to try and figure out what it is now. It does appear to be more some sort of memory alignment oddity rather than some sort of instruction throughput oddity. Anyone want to explain this for an inquisitive mind? :D Edit 3: Interjay has a point on the unrolling that blows the previous edit out of the water. With an unrolled loop the performance does not improve. You need to add a nop in to make the gap between jump source and destination the same as for my good nop count above. Performance still sucks. Its interesting that I need 6 nops to improve performance though. I wonder how many nops the processor can issue per cycle? If its 3 then that account for the cache write latency ... But, if thats it, why is the latency occurring? Curiouser and curiouser ...

• An intern interview with Microsoft [on hold]

  - by Wobbles

  I'm currently in my second year(Computer Science and Mathematics). In two days I have an interview on campus with Microsoft. I'm a bit nervous, because this will be my first in person interview. I have done reviewed basic things like linked list and binary trees. I am not really sure what kinds of questions I'll be asked. Has anyone been to such interview? If so what's it like? What kinds of questions will I be asked? Any help/suggestions will be much appreciated! Also can someone provide me with a list of things I ought to know for the interview?

• SQL Server, Generate scripts, unencrypted stored procedures only

  - by PeterO

  I have a SQL Server database with 3195 stored procedures. Most (approx 90%) of the stored procedures are encrypted (it's a 3rd party app) but there are many that are not encrypted (added by consultants later). I need to get an overview of the unencrypted stored procedures created by consultants and then apply fixes so that they can work with UTC time. I use Generate Scripts and select only stored procedures but that fails. I assume that is because the first stored procedure that it tries to write out is encrypted. Is there a way to write out the approx 300 stored procedures that are not encrypted?

• What would you do if you coded a C++/OO cross-platform framework and realize its laying on your disk

  - by Manuel

  This project started as a development platform because i wanted to be able to write games for mobile devices, but also being able to run and debug the code on my desktop machine too (ie, the EPOC device emulator was so bad): the platforms it currently supports are: Window-desktop WinCE Symbian iPhone The architecture it's quite complete with 16bit 565 video framebuffer, blitters, basic raster ops, software pixel shaders, audio mixer with shaders (dsp fx), basic input, a simple virtual file system... although this thing is at it's first write and so there are places where some refactoring would be needed. Everything has been abstracted away and the guiding principle are: mostly clean code, as if it was a book to just be read object-orientation, without sacrifying performances mobile centric The idea was to open source it, but without being able to manage it, i doubt the software itself would benefit from this move.. Nevertheless, i myself have learned a lot from unmaintained projects. So, thanking you in advance for reading all this... really, what would you do?

• How to sanely read and dump structs to disk when some fields are pointers?

  - by bp

  Hello, I'm writing a FUSE plugin in C. I'm keeping track of data structures in the filesystem through structs like: typedef struct { block_number_t inode; filename_t filename; //char[SOME_SIZE] some_other_field_t other_field; } fs_directory_table_item_t; Obviously, I have to read (write) these structs from (to) disk at some point. I could treat the struct as a sequence of bytes and do something like this: read(disk_fd, directory_table_item, sizeof(fs_directory_table_item_t)); ...except that cannot possibly work as filename is actually a pointer to the char array. I'd really like to avoid having to write code like: read(disk_df, *directory_table_item.inode, sizeof(block_number_t)); read(disk_df, directory_table_item.filename, sizeof(filename_t)); read(disk_df, *directory_table_item.other_field, sizeof(some_other_field_t)); ...for each struct in the code, because I'd have to replicate code and changes in no less than three different places (definition, reading, writing). Any DRYer but still maintainable ideas?

• Identify the checkbox that is checked

  - by lucky

  Hello Everyone, I have 2 checkboxes in a form and onclick of these, some php code needs to be executed and based on the result of the code, the checkbox is checked or unchecked. So i have written onclick = document.formName.submit(); Now it is triggering the same page and i am able to write the code. I am not able to differentiate which checkbox is checked. I don't want to use the procedure of:- calling javascript and then storing the value of the checkbox in a variable and making this variable as invisible. I would like to write something like document.formName.submit('checkbox1'). So that i should be able to handle the value of this or i dont know. Please suggest me an alternative method or better approach.

• Writing to the middle of the file (without overwriting data)

  - by Andreas Bonini

  In windows is it possible through an API to write to the middle of a file without overwriting any data and without having to rewrite everything after that? If it's possible then I believe it will obviously fragment the file; how many times can I do it before it becomes a serious problem? If it's not possible what approach/workaround is usually taken? Re-writing everything after the insertion point becomes prohibitive really quickly with big (ie, gigabytes) files. Note: I can't avoid having to write to the middle. Think of the application as a text editor for huge files where the user types stuff and then saves. I also can't split the files in several smaller ones.

• use qt and django to create desktop apps

  - by sandra

  Hi guys, I had this idea of creating desktop apps using django. The principe being: - Write the django app, and use something like cherrypy to serve it. - Write a Qt app in C++ to access it and this by using QtWebview (webkit) I'd like to "bundle" this in a single app. The lighter, the better :) So here are my questions and if you have better ideas and suggestions, please share them :) Is it possible to serve a django app with a c++ one? (a c++ server embedding python)? anyone did this before? Do you have some articles, blog posts? Thanks a lot!

• Can you create a HIPAA compliant Amazon S3 Web Application?

  - by xkingpin

  I am facing some questions when trying to design an S3 application using ASP.NET MVC and trying to stay HIPAA compliant. My initial plan was to require an SSL connection to my web server, encrypt the images on my server, then send them to s3 using my private keys. Here's my obvious concerns: You cannot store unencrypted images in any temporary file cache when client views images within the browser. Even if I setup an ashx to generically handle the image in memory, couldn't this get stored in cache? Saying the images will be encrpyted because you will be connecting to my server via https still does not guarantee all browsers will not cache data. It's not possible to even consider the "Query String" with expiration option since data will be encrypted before being stored on disk at s3, and will again be decrypted at my server in memory. I think my only option would be to write/purchase some sort of ActiveX component that will not expose the image as a simple html image source or write my app as a client side WinForm application.

• Do people create and use Web Parts connections?

  - by Javaman59

  I've been writing some SharePoint web parts wich connect (as providers and consumers). I've found many difficulties, and (comparatively*) little material from the web, from books, or from microsoft.com, which is quite surprising as Web Parts have been around since 2003. This is making me think that although web part connections look like a first class feature in SharePoint, that in practice few people write connecting web parts, and few SharePoint users use them. Is this the case - that few developers write connecting web parts, and few users use them? *comparitively: A subjective impression. With each specific problem i usually find only a handful of web pages which address it, and as my problems seem to be fundamental ones (such which data type to wrap in an IWebPartRow), I expect a lot more search results.

• For what programs are Objective C and Ruby ideal on the Mac?

  - by Kurt

  Hi, as a Mac outsider it seems that two popular programming languages on the Mac appear to be Objective C and Ruby. From what I understand the main API Cocoa seems to be written in and optimized for Objective C, but it is also possible to use Ruby for that. Are there different areas where each language is ideal, for example, I could imagine Objective C could be ideal for a GUI layer, or standalone desktop app, and Ruby could be good for web services etc. What about classic business logic, or data access layers? What language would be a good choice for a library of services for example? Can we write a library in one language and link to it from a main program written in the other language? If I wanted to write a layered enterprise application using domain driven design and dependency injection which languages could support each concerns? Are things like DDD and DI common amongst Mac devs? Just a curious outsider.

• What is the impact of a CMS on page load time versus a static site?

  - by PleaseStand

  I am creating a 20-page site that will go on shared hosting. Each page will be about 20 KB (including HTML, CSS, and images common to all pages). To avoid manually adding navigation elements to each page, I am considering using a CMS. However, I am concerned that on a busy server, using a CMS would make the site load more slowly. In a shared hosting environment where PHP is run as a CGI binary, how much does a CMS (WordPress, Drupal, etc.) generally affect page load time, compared to both "plain HTML" static sites and those using PHP as merely a templating language?
