• Is there a process-oriented IDE ?

  - by Raveline

  My problem is simple : when I'm programming in an OO paradigm, I'm often having part of a main business process divided in many classes. Which means, if I want to examine the whole functional chain that leads to the output, for debugging or for optimization research, it can be a bit painful. So I was wondering : is there an IDE that let you put a "process tag" on functions coming from different objects, and give you a view of all those functions having the same tag ? edit : To give an example (that I'm making up completely, sorry if it doesn't sound very realistic). Let's say we have the following business process for a HR application : receive a holiday-request by an employee, check the validity of the request, then give an alert to his boss ("one of those lazy programmer wants another day off"); at the same time, let's say the boss will want to have a table of all employee's timetable during the time the employee wants his vacations; then handle the answer of the boss, send a nice little mail to the employee ("No way, lazy bones"). Even if we get rid of everything not purely business-related (mail sending process, db handling to get the useful info, GUI functionalities, and so on), we still have something that doesn't really fit in "one class". I'd like to have an IDE that would give me the opportunity to embrace quickly, at the very least : The function handling the validation of the request by the employee; The function preparing the "timetable" for the boss; The function handling the validation of the request by the boss; I wouldn't put all those functions in the same class (but perhaps that's my mistake ?). This is where my dreamed IDE could be helpful.

• What packages are neccessary to have sound output from java applets?

  - by MvG

  I've got a very minimalistic setup of ubuntu precise, created using debootstrap. So please don't assume that any packages are installed just because they usually are. On that system, I'd like to play some sounds from a java applet. However, this always fails with the following error message: javax.sound.midi.MidiUnavailableException: Can not open line at com.sun.media.sound.SoftSynthesizer.open(SoftSynthesizer.java:1132) at com.sun.media.sound.SoftSynthesizer.open(SoftSynthesizer.java:1036) ... Caused by: java.lang.IllegalArgumentException: No line matching interface SourceDataLine supporting format PCM_SIGNED 44100.0 Hz, 16 bit, stereo, 4 bytes/frame, little-endian is supported. at javax.sound.sampled.AudioSystem.getLine(AudioSystem.java:476) at javax.sound.sampled.AudioSystem.getSourceDataLine(AudioSystem.java:604) at com.sun.media.sound.SoftSynthesizer.open(SoftSynthesizer.java:1066) ... 35 more As the messages mention a soft synthesizer, and pcm lines, I expect that the lack of some midi daemon is not the issue here. As far as I can tell, the alsa kernel modules are loaded, including snd_hda_intel, snd_pcm, snd_seq_midi among others. I've also included the alsa-base and alsa-utils packages in my installation. alsa-mixer looks good, using “HDA Intel PCH” as its default device. What other packages, configuration settings or daemon startups does java require to make its sound output work?

• Jump handling and gravity

  - by sprawl

  I'm new to game development and am looking for some help on improving my jump handling for a simple side scrolling game I've made. I would like to make the jump last longer if the key is held down for the full length of the jump, otherwise if the key is tapped, make the jump not as long. Currently, how I'm handling the jumping is the following: Player.prototype.jump = function () { // Player pressed jump key if (this.isJumping === true) { // Set sprite to jump state this.settings.slice = 250; if (this.isFalling === true) { // Player let go of jump key, increase rate of fall this.settings.y -= this.velocity; this.velocity -= this.settings.gravity * 2; } else { // Player is holding down jump key this.settings.y -= this.velocity; this.velocity -= this.settings.gravity; } } if (this.settings.y >= 240) { // Player is on the ground this.isJumping = false; this.isFalling = false; this.velocity = this.settings.maxVelocity; this.settings.y = 240; } } I'm setting isJumping on keydown and isFalling on keyup. While it works okay for simple use, I'm looking for a better way handle jumping and gravity. It's a bit buggy if the gravity is increased (which is why I had to put the last y setting in the last if condition in there) on keyup, so I'd like to know a better way to do it. Where are some resources I could look at that would help me better understand how to handle jumping and gravity? What's a better approach to handling this? Like I said, I'm new to game development so I could be doing it completely wrong. Any help would be appreciated.

• Real world pitfalls of introducing F# into a large codebase and engineering team

  - by nganju

  I'm CTO of a software firm with a large existing codebase (all C#) and a sizable engineering team. I can see how certain parts of the code would be far easier to write in F#, resulting in faster development time, fewer bugs, easier parallel implementations, etc., basically overall productivity gains for my team. However, I can also see several productivity pitfalls of introducing F#, namely: 1) Everyone has to learn F#, and it's not as trivial as switching from, say, Java to C#. Team members that have not learned F# will be unable to work on F# parts of the codebase. 2) The pool of hireable F# programmers, as of now (Dec 2010) is non-existent. Search various software engineer resume databases for "F#", way less than 1% of resumes contain the keyword. 3) Community support as of now (Dec 2010) is less available. You can google almost any problem in C# and find someone that has already dealt with it, not so with F#. Third party tool support (NUnit, Resharper etc) is also sketchy. I realize that this is a bit Catch-22, i.e. if people like me don't use F# then the community and tools will never materialize, etc. But, I've got a company to run, and I can be cutting edge but not bleeding edge. Any other pitfalls I'm not considering? Or anyone care to rebut the pitfalls I've mentioned? I think this is an important discussion and would love to hear your counter-arguments in this public forum that may do a lot to increase F# adoption by industry. Thanks.

• What You Said: Desktop vs. Web-based Email Cients

  - by Jason Fitzpatrick

  We clearly tapped into a subject you all have a strong opinion about with this week’s Ask the Readers post; read on to see how your fellow readers manage their email on, off, and across desktops and devices. Earlier this week we asked you to share your email workflow and you all responded in force. TusconMatt doesn’t miss desktop clients one bit: Switched to Gmail years ago and never looked back. No more losing my emails and contacts if my HDD crashes or when I reinstall. No more frustration with not being able to access an email on the road because it downloaded to my drive and deleted from the server. No more mailbox full messages because I left messages on the server to avoid the above problem! I love having access to all emails from anywhere on any platform and don’t think I could ever go back to a dedicated email client.

• Linux stretch cluster: MD replication, DRBD or Veritas?

  - by PieterB

  For the moment there's a lot of choices for setting up a Linux cluster. For cluster manager: you can use Red Hat Cluster manager, Pacemaker or Veritas Cluster Server. The first one has the most momentum, the second one comes by default with RH subscriptions and the last one is very expensive and has a very good reputation ;-) For storage: - You can replicate LUN's using software raid / md device - You can use the network using DRBD replication, which offers a bit more flexibility - You can use Veritas Storage Foundation technology to talk to your SANs replication technology. Anyone has any recommandations or experience with these technologies?

• How to recursively move all files (including hidden) in a subfolder into a parent folder in *nix?

  - by deadprogrammer

  This is a bit of an embracing question, but I have to admit that this late in my career I still have questions about the mv command. I frequently have this problem: I need to move all files recursively up one level. Let's say I have folder foo, and a folder bar inside it. Bar has a mess of files and folders, including dot files and folders. How do I move everything in bar to the foo level? If foo is empty, I simply move bar one level above, delete foo and rename bar into foo. Part of the problem is that I can't figure out what mv's wildcard for "everything including dots" is. A part of this question is this - is there an in-depth discussion of the wildcards that cp and mv commands use somewhere (googling this only brings very basic tutorials).

• Word 2007, Adding Page Numbers to Landscape, 5.5 by 8.5 Booklet Style Document

  - by nicorellius

  I am publishing a 5.5 by 8.5 booklet. I created this document in Word 2007 and will be converting it to PDF. It looks good as is, but I can't seem to figure out how to add page numbers automatically to this document. In general, I know how to add page numbers using footers, etc, but this application is a bit different: I have two pages (5.5 by 8.5) on one landscape 8.5 by 11 page. See picture below: I guess I could manually add page numbers, but then getting the formatting perfect will be tough. Any ideas?

• I know fundamental programming. But how do I get started in game development now?

  - by Rohan Menon

  I'm a 20 year old programming student. I know fundamental programming in BASIC, C, C++ and JAVA. What I wanted to ask is, where do I go from here? Are there any books that the community can mention that will help me develop a game or at least learn game development? I've had a lot of ideas and really want to make some sort of prototype to see if I'm suited for the industry. I really don't mind learning any new languages but I need to know what I should begin with. A good book that will help with a little more understanding as I go up will be very helpful. Maybe a tutorial to develop some basic 2D games like a side-scroller, snake or pocket tanks in an easy to understand SDK? I know that to get some credit under your belt, you need to be able to make a few games on your own. Also, what platform should I start on? The PC, iOS or Android (as an introduction) for now. I don't want to get into high level game design just yet. Just something a bit basic to help out in future development. Anything pointing me in the right direction will be really really helpful. Edit: Also, I want to say that I'm looking towards this from a game designer's point of view more than a game programmer. I want suggestions on any SDKs or easy to use programs I can use to understand game design. Then delve deeper into the programming after that. Not as employment but as developing your own games (for now).

• How do I get OBDII software working?

  - by NoBugs

  I have an ODBII USB cable for vehicle diagnostics, unfortunately I haven't been able to get it working on Ubuntu 12.04. The closest I've come is using the VAG-COM software with wine, using the ln -s /dev/ttyUSB0 ~/.wine/dosdevices/com1 trick and running stty -F /dev/ttyUSB0 speed 9600 repeatedly. It will connect and show the vehicle is OBDII, but none of the useful features seem to be working. I tried: Scantool - says it's connecting to the /dev/device in terminal, but doesn't. obdgpslogger - times out all the time. pyobd - This seems to be the most up-to-date source I could find, I had to adjust the code a bit to work (see here for changes). Still, in obd_io.py interpret_result function, it says it's looking for 4 space separated numbers, where the usb-serial is receiving bogus code "0100" instead? The device shows up in lsusb as: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC Is the problem that these native tools don't expect a USB serial, or a serial of this type? Or are these apps too old to recognize OBD2 of this vehicle?

• Is it possible to use Sharepoint 2007 without installing it?

  - by foxtrot

  Hi there! My company wants to buy Sharepoint 2007 and they asked me if I could give an opinion. I've saw already a lot of videos and read e-books but would like to use it for a while, specially the integration with Sharepoint Designer 2007. The only way to do that is installing it on a trial basis? Is there any other way? Any available public installation? I only have an old 32-bit laptop with Windows XP. Thanks in advance!

• How to recover from terminal custom setup

  - by linq

  I installed ubuntu 12.04 and I added "Terminal" to the launcher bar, the default size of the terminal is a bit small, after some googling here is how I made the disaster change: At HUD menu, type "preference" and I see the option of Edit > preference, this is as I expected After I clicked the option, I forget the exact steps, but somehow I came to some configuration panel and there is a checkbox for terminal "custom" and I checked it now an input box is enabled and I type gnome-terminal --geometry 160x50 Now the problem comes, whenever I click the terminal button at the launcher bar, new terminal windows pops up endlessly from everywhere, I cannot do anything any more except logout or shutdown. The weird thing is, after I come back, I cannot get that Edit > preference any more when I type "preference" in HUD, I tried "Edit", "preference". To be clear, I still can use the computer as long as I do not click that terminal button, but I really want to use terminal to run commands. Help is appreciated greatly! Update - OK, figured out. Go to /home/jibin/.gconf/apps/gnome-terminal/profiles/Default and open that xml file, I can see the options I changed at the GUI, remove them and terminal runs good. The preference HUD is back also, it is actually Profile Preference and it is only available when terminal is open. Continue my ubuntu-ing...

• Static "LoD" hack opinions

  - by David Lively

  I've been playing with implementing dynamic level of detail for rendering a very large mesh in XNA. It occurred to me that (duh) the whole point of this is to generate small triangles close to the camera, and larger ones far away. Given that, rather than constantly modifying or swapping index buffers based on a feature's rendered size or distance from the camera, it would be a lot easier (and potentially quite a bit faster), to render a single "fan" or flat wedge/frustum-shaped planar mesh that is tessellated into small triangles close to the near or small end of the frustum and larger ones at the far end, sort of like this (overhead view) (Pardon the gap in the middle - I drew one side and mirrored it) The triangle sizes are chosen so that all are approximately the same size when projected. Then, that mesh would be transformed to track the camera so that the Z axis (center vertical in this image) is always aligned with the view direction projected into the XZ plane. The vertex shader would then read terrain heights from a height texture and adjust the Y coordinate of the mesh to match a height field that defines the terrain. This eliminates the need for culling (since the mesh is generated to match the viewport dimensions) and the need to modify the index and/or vertex buffers when drawing the terrain. Obviously this doesn't address terrain with overhangs, etc, but that could be handled to a certain extent by including a second mesh that defines a sort of "ceiling" via a different texture. The other LoD schemes I've seen aren't particularly difficult to implement and, in some cases, are a lot more flexible, but this seemed like a decent quick-and-dirty way to handle height map-based terrain without getting into geometry manipulation. Has anyone tried this? Opinions?

• How to force-restart a PC with vPro technology?

  - by Dan Nissenbaum

  I would like to know how to force-restart a PC that has crashed/hung and become completely non-responsive, using 2nd-generation vPro technology. Assume there is a second, fully responsive PC on the same LAN that can be accessed remotely to assist. Specifically, I am considering purchasing a PC with an i7-2860QM CPU, which is vPro-enabled (according to Intel). Here are two links that indicate it should be possible to force-restart a hung system with a 2nd-generation vPro-enabled CPU: Seconds 24-39 of What Is Intel vPro™ Technology? Page 17 (21 of the PDF) of Intel® vPro™ Technology: Reference Guide However, after extensive research, I cannot find a straightforward and trustworthy source of confirmation that this will actually work as I describe, or any documentation about how to set it up. I would appreciate both a reliable confirmation, and a source of documentation. This question is a follow-up to: Wake-on-LAN (WOL) fails after computer crashes (Windows 7 64-bit).

• deep expertise in one technology or not so deep understanding of many technologies

  - by district

  Hello everyone. I started to feel a little bit confused recently about my career path as software developer, about what I do, what I know and do I need it. I am 21 years now and I have 3 years of experience. I've been dealing with java/C++ projects, Servlet/JSP/JSF, desktop QT, also some mobile development (Symbian, Android) I work for a quite a small company, around 20 developers with different projects. I'm also a student. The problem is that I'm not sure if I'm taking the right road here. I'm starting to work with new technology every few months. I don't have deep understanding in any of these and I'm not sure if this is what I need. I will probably not become an expert in any of these. The other path is maybe to start working for a big company which use one set of technologies and become an expert. What's your opinion on this topic ? What is more valuable ?

• Suggested Resources Visual Studio Plug-In

  Todays post is a quick plug for a new tool developed by my friend Olaf Conijn, who (amongst other things) has been a developer on several versions of Enterprise Library. His new tool is called Suggested Resources for .NET Developers, and the current 0.8 release works with both Visual Studio 2008 and Visual Studio 2010. So what does it do? Well heres what Olaf has to say: This Visual Studio Integration Package is a proof of concept in: Aggregation of online content within the Visual Studio IDE. Analysis of development activities within the Visual Studio IDE. This combination of features allows Suggested Resources for .NET developers to pro-actively suggest online content that applies on the task being performed by a developer... A bit like having a programming pair that searches for online resources while you focus on getting the job done. For more info, screenshots and downloads, head to the Codeplex project site or the Visual Studio Gallery page.Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Pre game loading time vs. in game loading time

  - by Keeper

  I'm developing a game in which a random maze is included. There are some AI creatures, lurking the maze. And I want them to go in some path according to the mazes shape. Now there are two possibilities for me to implement that, the first way (which I used) is by calculating several wanted lurking paths once the maze is created. The second, is by calculating a path once needed to be calculated, when a creature starts lurking it. My main concern is loading times. If I calculate many paths at the creating of the maze, the pre loading time is a bit long, so I thought about calculating them when needed. At the moment the game is not 'heavy' so calculating paths in mid game is not noticeable, but I'm afraid it will once it will get more complicated. Any suggestions, comments, opinions, will be of help. Edit: As for now, let p be the number of pre-calculated paths, a creatures has the probability of 1/p to take a new path (which means a path calculation) instead of an existing one. A creature does not start its patrol until the path is fully calculated of course, so no need to worry about him getting killed in the process.

• How do I install Postgres Graphical Installer?

  - by Tusar Das

  I am a newbie in using Ubuntu (more precisely never used linux except the production deployment ). Now I choose to hold a grip on the system and intalled a latest 11.10 Ubuntu in my 32 bit Intel** desktop. In this machine **I have a 'administrator' user 'tusar'. I want to install the PostgreSQL graphical version so downloaded this file postgresql-8.4.9-1-linux.bin from here Now If run the file with ./filename command (refuses if I am not root), it opens up the graphical interface and completes the installation (creates user postgres and ask for password, wont complete if I dont give valid password). I checked with /etc/inint.d/postgresql-8.4 status , that postgres is running. But the problem is I am unable to open the GUI (I installed it in /opt/Postgresql ), its telling permission denied even if I am logged in as 'tusar'. Then I tried using the su postgres command and it directly changed the user without password. Now if I run the psql , createdb , its prompting me to install the postgres-client-package but this utilies are already installed and I can view them in my /opt/Postgresql/8.4/bin folder. I can run query through my JDBC utility programs but unable to use neither terminal nor the graphical interface (although I can see pgAdmin3 is there ). Urgent help needed. I have used this guide for the installation.

• Sorting a Grid of Data in ASP.NET MVC

  Last week's article, Displaying a Grid of Data in ASP.NET MVC, showed, step-by-step, how to display a grid of data in an ASP.NET MVC application. Last week's article started with creating a new ASP.NET MVC application in Visual Studio, then added the Northwind database to the project and showed how to use Microsoft's Linq-to-SQL tool to access data from the database. The article then looked at creating a Controller and View for displaying a list of product information (the Model). This article builds on the demo application created in Displaying a Grid of Data in ASP.NET MVC, enhancing the grid to include bi-directional sorting. If you come from an ASP.NET WebForms background, you know that the GridView control makes implementing sorting as easy as ticking a checkbox. Unfortunately, implementing sorting in ASP.NET MVC involves a bit more work than simply checking a checkbox, but the quantity of work isn't significantly greater and with ASP.NET MVC we have more control over the grid and sorting interface's layout and markup, as well as the mechanism through which sorting is implemented. With the GridView control, sorting is handled through form postbacks with the sorting parameters - what column to sort by and whether to sort in ascending or descending order - being submitted as hidden form fields. In this article we'll use querystring parameters to indicate the sorting parameters, which means a particular sort order can be indexed by search engines, bookmarked, emailed to a colleague, and so on - things that are not possible with the GridView's built-in sorting capabilities. Like with its predecessor, this article offers step-by-step instructions and includes a complete, working demo available for download at the end of the article. Read on to learn more! Read More >

• Graduate expectations versus reality

  - by Bobby Tables

  When choosing what we want to study, and do with our careers and lives, we all have some expectations of what it is going to be like. Now that I've been in the industry for almost a decade, I've been reflecting a bit on what I thought (back when I was studying Computer Science) programming working life was going to be like, and how it's actually turning out to be. My two biggest shocks (or should I say, broken expectations) by far are the sheer amount of maintenance work involved in software, and the overall lack of professionalism: Maintenance: At uni, we were all told that the majority of software work is maintenance of existing systems. So I knew to expect this in the abstract. But I never imagined exactly how overwhelming this would turn out to be. Perhaps it's something I mentally glazed over, and hoped I'd be building cool new stuff from scratch a lot more. But it really is the case that most jobs are overwhelmingly maintenance, bug fixing, and support oriented. Lack of professionalism: At uni, I always had the impression that commercial software work is very process-oriented and stringently engineered. I had images of ISO processes, reams of technical documentation, every feature and bug being strictly documented, and a generally professional environment. It came as a huge shock to realise that most software companies operate no differently to a team of students working on a large semester-long project. And I've worked in both the small agile hack shop, and the medium sized corporate enterprise. While I wouldn't say that it's always been outright "unprofessional", it definitely feels like the software industry (on the whole) is far from the strong engineering discipline that I expected it to be. Has anyone else had similar experiences to this? What are the ways in which your expectations of what our profession would be like were different to the reality?

• At which point is a continuous integration server interesting?

  - by Cedric Martin

  I've been reading a bit about CI servers like Jenkins and I'm wondering: at which point is it useful? Because surely for a tiny project where you'd have only 5 classes and 10 unit tests, there's no real need. Here we've got about 1500 unit tests and they pass (on old Core 2 Duo workstations) in about 90 seconds (because they're really testing "units" and hence are very fast). The rule we have is that we cannot commit code when a test fail. So each developers launches all his tests to prevent regression. Obviously, because all the developers always launch all the test we catch errors due to conflicting changes as soon as one developer pulls the change of another (when any). It's still not very clear to me: should I set up a CI server like Jenkins? What would it bring? Is it just useful for the speed gain? (not an issue in our case) Is it useful because old builds can be recreated? (but we can do this to with Mercurial, by checking out old revs) Basically I understand it can be useful but I fail to see exactly why. Any explanation taking into account the points I raised above would be most welcome.

• When using TCP load balancing with HAProxy, does all outbound traffic flow through the LB?

  - by user122875

  I am setting up an app to be hosted using VMs(probably amazon, but that is not set in stone) which will require both HTTP load balancing and load balancing a large number(50k or so if possible) of persistant TCP connections. The amount of data is not all that high, but updates are frequent. Right now I am evaluating load balancers and am a bit confused about the architecture of HAProxy. If I use HAProxy to balance the TCP connections, will all the resulting traffic have to flow through the load balancer? If so, would another solution(such as LVS or even nginx_tcp_proxy_module) be a better fit?

• An ideal way to decode JSON documents in C?

  - by AzizAG

  Assuming I have an API to consume that uses JSON as a data transmission method, what is an ideal way to decode the JSON returned by each API resource? For example, in Java I'd create a class for each API resource then initiate an object of that class and consume data from it. for example: class UserJson extends JsonParser { public function UserJson(String document) { /*Initial document parsing goes here...*/ } //A bunch of getter methods . . . . } The probably do something like this: UserJson userJson = new UserJson(jsonString);//Initial parsing goes in the constructor String username = userJson.getName();//Parse JSON name property then return it as a String. Or when using a programming language with associative arrays(i.e., hash table) the decoding process doesn't require creating a class: (PHP) $userJson = json_decode($jsonString);//Decode JSON as key=>value $username = $userJson['name']; But, when I'm programming in procedural programming languages (C), I can't go with either method, since C is neither OOP nor supports associative arrays(by default, at least). What is the "correct" method of parsing pre-defined JSON strings(i.e., JSON documents specified by the API provider via examples or documentation)? The method I'm currently using is creating a file for each API resource to parse, the problem with this method is that it's basically a lousy version of the OOP method, as it looks exactly like the OOP method but doesn't provide any OOP benefits(e.g., can't pass an object of the parser, etc.). I've been thinking about encapsulating each API resource parser file in a publicly accessed structure(pointing all functions/publicly usable variables to the structure) then accessing the parser file code from within the structure(parser.parse(), parser.getName(), etc.). As this way looks a bit better than the my current method, it still just a rip off the OOP way, isn't it? Any suggestions for methods to parse JSON documents on procedural programming lanauges? Any comments on the methods I'm currently using(either 3 of them)?
