• Hardware Lossless Compression for Hard Drives?

  - by GeoffreyF67

  I happened across this article about hardware based hard drive encryption and realized that not only would this give a great way to protect your data but it would also speed up the applications that we use to encrypt that data. This lead me to wonder... Would it be possible to do the same thing for compression so that all of the data is compressed or uncompressed appropriately as it is read and written to the drive? I haven't done any firmware programming in quite some time so I'm not even sure this is technically possible. If it were, however, it could probably give quite a bit more storage space to folks. What are the pros and cons of programming such an approach to be used in the firmware? G-Man

• JMS/DDS Integration

  - by dalenkruse

  I have a legacy C++ application that uses DDS for asynchronous communication/messaging. I need to integrate this application into a JavaEE environment that uses JMS for messaging. Other than building a standalone JMS/DDS bridge module, are there any other options that I might have?

• What is node.js?

  - by Jeffrey

  I don't fully get what node.js is all about. Maybe it's because I am mainly a web based business app developer. Can someone please explain what it is and the use of it? Thanks. My understanding so far is that: The programming model is event driven, especially the way it handles IO. It uses javascript and the parser is V8. It can be easily used to create concurrent server apps. Are my understandings correct? If yes, then what are the benefits of evented IO, is it just more for the concurrency stuffs? Also is the direction of node.js to become a framework like, javascript based (v8 based) programming model?

• Interviewing - convincing young interviewers that my experience matters [closed]

  - by ritu

  As requested, I split this question from a two part question I asked at http://stackoverflow.com/questions/2482071/modern-web-development-general-question My question is how do i convince the young programmers who interview me that my years of system programming experience, MFC, Win32 programming are still relevant and I should not be automatically rejected because I don't know the differences between Drupal and <pick your technology>. It seems like I can ask a dozen question that these guys won't be able to answer but somehow because I don't know the latest fad counts against me. I do read, but if you don't use what you read in your daily work, you will never have expert knowledge of it. So bottom line: is the only way for me to take a .NET or Java job is for me to start at the bottom all over?

• Keyboard layout for international programmers?

  - by splattne

  I think everybody who had to program using a standard German (or any other international) keyboard layout on Windows (or Mac) will complain about the conundrum of either having all special characters ( [ ] | { } / etc. ) needed for most programming languages "at the fingertip" and "losing" the language specific characters (umlauts ä ö ü etc.) on the keyboard or viceversa: having simple access to umlauts, but not to brackets etc. If you are programming in C / C++ / C# / Java / Javascript for example, it is very exhausting if you have to press Alt-Gr + 7 for every opening curly bracket. It is an ergonomic nightmare and reduces your typing efficiency. What is the best way to cope with this problem? Is there a satisfying solution? Maybe there are special layouts or keyboards which address this issue?

• Unix file naming convention for effective tab completion?

  - by thebossman

  I feel like I often name files in such a way that my computer constantly beeps while I program because the tab completion is ambiguous. Before doing a lot of Unix programming, I tended to name related files with the same prefix to indicate their relation. Now I must re-think my approach to folder and file structures and names to program more effectively. What heuristics or rules do you apply when programming to simplify tab completion? Do you use any tools to make tab completion smoother (e.g., emacs icicles)?

• GOTO still considered harmful?

  - by Kyle Cronin

  Everyone is aware of Dijkstra's Letters to the editor: go to statement considered harmful (also here .html transcript and here .pdf) and there has been a formidable push since that time to eschew the goto statement whenever possible. While it's possible to use goto to produce unmaintainable, sprawling code, it nevertheless remains in modern programming languages. Even the advanced continuation control structure in Scheme can be described as a sophisticated goto. What circumstances warrant the use of goto? When is it best to avoid? As a followup question: C provides a pair of functions, setjmp and longjmp, that provide the ability to goto not just within the current stack frame but within any of the calling frames. Should these be considered as dangerous as goto? More dangerous? Dijkstra himself regretted that title, of which he was not responsible for. At the end of EWD1308 (also here .pdf) he wrote: Finally a short story for the record. In 1968, the Communications of the ACM published a text of mine under the title "The goto statement considered harmful", which in later years would be most frequently referenced, regrettably, however, often by authors who had seen no more of it than its title, which became a cornerstone of my fame by becoming a template: we would see all sorts of articles under the title "X considered harmful" for almost any X, including one titled "Dijkstra considered harmful". But what had happened? I had submitted a paper under the title "A case against the goto statement", which, in order to speed up its publication, the editor had changed into a "letter to the Editor", and in the process he had given it a new title of his own invention! The editor was Niklaus Wirth. A well thought out classic paper about this topic, to be matched to that of Dijkstra, is Structured Programming with go to Statements (also here .pdf), by Donald E. Knuth. Reading both helps to reestablish context and a non-dogmatic understanding of the subject. In this paper, Dijkstra's opinion on this case is reported and is even more strong: Donald E. Knuth: I believe that by presenting such a view I am not in fact disagreeing sharply with Dijkstra's ideas, since he recently wrote the following: "Please don't fall into the trap of believing that I am terribly dogmatical about [the go to statement]. I have the uncomfortable feeling that others are making a religion out of it, as if the conceptual problems of programming could be solved by a single trick, by a simple form of coding discipline!"

• WCF - Compact Framework - Pull data from mobile client

  - by jagse

  Hello guys, I want to communicate xml serialized objects from the server to the client and the other way arround. Now it is (probably) easy to invoke methods from a mobile client (compact framework) using WCF, but is there a way so that the server can invoke methods on the client side or some other way to pull data from the client? I know that callback contracts are not available in the compact framework as you can see here: http://blogs.msdn.com/andrewarnottms/archive/2007/09/13/calling-wcf-services-from-netcf-3-5-using-compact-wcf-and-netcfsvcutil-exe.aspx Originally I thought of socket programming and of developing this by myself, then someone here mentioned WCF. But it seems like WCF only would work in a non mobile environment as I need callbacks. Anyone can help me with this? Is it possible to develop a two way communication with a desktop server and multiple mobile clients using WCF, or will I have to do socket programming? Thanks for any advice or any kind of help!

• Reactive extensions for Javascript code examples

  - by Tuomas Hietanen

  Microsoft have published Reactive Extensions for Javascript. It should make asynchronous (and event based) web-ui programming easy. There are currently a video and some tutorials. But how cool UI could I really make? Do you know any good demos or code examples using rx.js?

• How can I enjoy or avoid designing every web application I make ?

  - by schmrz

  I know this sounds silly, but I'm having huge problems (ok, not that huge, but still...) problems when I get an idea for a web project, small or big. The instant turn off is when I remember that I have to code the html/css by hand again and again. I like programming a lot more that designing web sites, and I simply don't enjoy designing them as much as I enjoy programming them. With that said, I also prefer simple and minimalistic designs. What is your approach in web design, how do you make it enjoyable (at least a little bit)?

• Are there any famous one-man-army programmers?

  - by DFectuoso

  Lately I have been learning of more and more programmers who think that if they were working alone, they would be faster and would deliver more quality. Usually that feeling is attached to a feeling that they do the best programming in their team and at the end of the day the idea is quite plausible. If they ARE doing the best programming, and worked alone (and more maybe) the final result would be a better piece of software. I know this idea would only work if you where enough passionate to work 24/7, on a deadline, and great discipline. So after considering the idea and trying to learn a little more, I wonder if there are famous one-man-army programmers that have delivered any (useful) software in the past?

• Winforms Which Design Pattern / Agile Methodology to choose

  - by ZedBee

  I have developed desktop (winforms) applications without following any proper design pattern or agile methodologies. Now I have been given the task to re-write an existing ERP application in C# (Winforms). I have been reading about Domain Driven Design, scrum, extreme programming, layered architecture etc. Its quite confusing and really hard (because of time limitations) to go and try each and every method and then deciding which way to go. Its very hard for me to understand the bigger picture and see which pattern and agile methodology to follow. To be more specific about what I want to know is that: Is it possible to follow Domain Driven Design and still be agile. Should I choose Extreme programming or scrum in this specific scenario Where does MVP and MVVM fits, which one would be a better option for me

• how do I know when/where to invoke the overridden method of the super class

  - by Henry

  Hi, This question occured to me while programming a Android application, but it seems to be a general programming question more. The situation is, I am extending (subclass-ing) an class from a library, and overriding a method. how do I know if I should invoke the method of super-class? and when? (in the beginning of the overridden method or in the end?) For example, I am overriding the method "public boolean onCreateOptionsMenu(Menu menu)" from class "Activity" in Android platform. And I saw someone write "return super.onCreateOptionsMenu(menu)" in the end of the method, in an example. But how do I know it should be done this way? and it is correct or not? what's the difference if I begin my method with "super.onCreateOptionsMenu(menu)"? BR, Henry

• Google Wave as code repository and IDE?

  - by dehmann

  Is it possible to write a Google Wave plugin that turns it into an IDE for programming? With such an extension, Google Wave would be a replacement for Eclipse etc., and it would naturally be a code repository at the same time (replacing SVN, git, etc.). Users (programmers) would be able to create code files directly in Wave and add collaborators to do pair programming etc. The whole codebase would live in a Wave folder, and an extension would do the building and compiling on the fly. How would one go about writing such an extension?

• Has there been a Firefox update recently?

  - by Rob Nicholson

  Trying again to ask a PROGRAMMING question because of the over-zealous closing off of what is equally a programming question before allowing the poster to clarify. The latest version of Firefox (v3.6.3) is breaking websites, mine included. I make heavy use of the Infragistic NetAdvantage controls. These, because of their heavy JavaScript reliance and occasional lack of quality control, tend to suffer through browser updates sometimes requiring a hotfix. So the question is... has there been a Firefox release recently that has either introduced a bug, tightening up of some standard, bug fix which might have broken a previous workaround (often the case) etc? I'm guessing around JavaScript but that's a guess hence the reason for asking a group of programmers...

• Does python's httplib.HTTPConnection block?

  - by python_noob

  Hello, I am unsure whether or not the following code is a blocking operation in python: import httplib import urllib def do_request(server, port, timeout, remote_url): conn = httplib.HTTPConnection(server, port, timeout=timeout) conn.request("POST", remote_url, urllib.urlencode(query_dictionary, True)) conn.close() return True do_request("http://www.example.org", 80, 30, "foo/bar") print "hi!" And if it is, how would one go about creating a non-blocking asynchronous http request in python? Thanks from a python noob.

• Is TcpClient BeginRead/Send thread safe?

  - by wb

  Using a dotNET TcpClient if I have called an asynchronous BeginRead() on the associated network stream can I still call Write() on that stream on another thread? Or do I have to lock() the TcpClient in the code that is called back from the BeginRead and the code that does the send? Also if I close the TcpClient with: client.GetStream().Close(); client.Close(); Do I have to lock() on the TcpClient as well? Thanks in advance.

• Is there a way to unit test an async method?

  - by Jiho Han

  I am using Xunit and NMock on .NET platform. I am testing a presentation model where a method is asynchronous. The method creates an async task and executes it so the method returns immediately and the state I need to check aren't ready yet. I can set a flag upon finish without modifying the SUT but that would mean I would have to keep checking the flag in a while loop for example, with perhaps timeout. What are my options?

• Synonym for "Many-to-Many" relationship (relational databases)

  - by Byron

  What's a synonym for a "many-to-many" relationship? I've finished writing an object-relational mapper but I'm still stumped as to what to name the function that adds that relation. addParent() and addChild() seemed quite logical for the many-to-one/one-to-many and addSuperclass() for one-to-one inheritance, but addManyToMany() would sound quite unintuitive to an object-oriented programmer. addSibling() or addCousin() doesn't really make sense either. Any suggestions? And before you dismiss this as a non-programming question, please remember that consistent naming schemes and encapsulation are pretty integral to programming :)

• Frustrated with Objective-c code...

  - by Moshe

  Well, I've started with iPod/iPhone programming using Head First iPhone Development (O'reilly) and I'm typing code out of the book. There are two problems, one is programming related and the other is not. I don't understand the format of objective-c methods. I'm getting an few errors now, based on source code from the book. Which leads me to my next issue. Some of the code is buggy. I think so because I couldn't get the code to run without modifying it. The book has some typos in the text since it's a first edition and whatnot, but could my "fixing" the code have to do with it? So... Where can I learn more about objective-c methods and how they work in terms of structure and where the return type and arguments go? For those with the book, I'm in the middle of the InstaTweet app towards the beginning. Thanks.

• Wanting a simple overview on how to connect to a SQLite database in Cocoa/Objective-C

  - by Jesse

  Hi, everyone. I've been experimenting with Cocoa and Objective-C programming on the Mac for a few months now, and I am wanting to start developing applications that manage large amounts of data. The trouble is, I'm not really sure where to start with databases. I have a good background in Java programming with SQLite. I've read a bit about CoreData and I haven't been able to find any good resources for just manually connecting to the database. I'm looking for recommendations. Should I try CoreData, and if so, can anyone recommend a good tutorial for someone new to the language? Or, should I try to manually connect and query an SQLite database somehow, and, if so, any tutorials? Any help would be greatly appreciated! Thanks!

• What is needed to get Delphi back on top?

  - by Jim McKeeth

  Delphi 2009 is due in the next couple months, which is its 12th release since Turbo Pascal became Delphi in 1995. Despite continued innovation it has not returned to its level of popularity before the Inprise fiasco. Many developers with Delphi backgrounds are moving to C# and many Delphi legacy applications are being rewritten in C#, despite the fact Delphi supports .NET and in many cases the existing application could be ported without rewriting. Is it just a losing battle to compete against Microsoft's tools on their platform? Is there something Code Gear / Delphi can do now that they are under new management to regain market share? What can enthusiasts do to help? Why do you do Delphi programming? or Why are you not doing Delphi programming?
