  • Write own messaging system vs. utilize existing ones

    - by A.Rashad
    We are trying to have our own startup, with a middleware application to glue small applications with enterprise legacy systems. for such middle-ware to function properly, we will need some sort of messaging system to make different components talk to each other in a reliable way. the alternatives are: use an existing messaging system, such as 0MQ, jBOSS, WebSphere MQ, etc. build our own messaging system the way we see the problem I am more biased towards the later option for the following reasons: to have more control over our final product to avoid any licensing problems later on to learn about messaging while writing the code to invent something new, that might cost us lots of $$$ if reused an existing system What would you do if in my shoes?

  • SATA hard disk for laptop on Desktop PC

    - by Lawliet
    I know that this forum is for programming-related questions only, but I'm having this dilemma so here I go. Can I connect a laptop SATA hard disk to Desktop PC? Do I have to use some adapters or I can just plug in SATA power connector and SATA data cable like my Desktop hard disk is connected? I noticed that both laptop and desktop SATA disks use same connectors, but I'm afraid that I might fry my laptop hard disk because the SATA connector has both 12V and 5V voltage (given the fact that laptop hard disks has input voltage of 5V) Thanks in advance

  • Representing heightmaps, on disk and when drawing

    - by gardian06
    This is a conglomeration question when answering please specify which part you are addressing. I am looking at creating a maze type game that utilizes elevation. I have a few features I would like to have, but am unsure as to some of the implementation. I have done work doing fileIO maze generation (using a key to read the file, and then generate the level based on that file), but I am unsure how to think about this with elevation in the mix. I think height maps might be a good approach, but don't know how to represent them effectively. for a height map which is more beneficial XML(containing h[u,v] data and key definition), CSV (item1 is key reference, item2 is elevation), or another approach that I have not thought of yet? When it comes to placing the elevation values themselves what kind of deltah values are appropriate to have it noticeable at about a 60degree angle while not really effecting gravity driven physics (assuming some effect while moving up/down hill)? I am thinking of maybe going to procedural generation at some point, but am wondering if it is practical to have a procedurally generated grid (wall squares possibly same dimensions as the open space squares), or if designing to a thin wall open spaces is better? this decision will effect the amount of work need on the graphics end for uniform vs. irregular walls. EDIT: Game will be a elevation maze shooter. Levels/maps will be mazes with elevation the player has to negotiate. Elevations will have effects on "combat" vision, and movement.

  • How to detect which edges of a rectange touch when they collide in iOS

    - by Mike King
    I'm creating a basic "game" in iOS 4.1. The premise is simple, there is a green rectangle ("disk") that moves/bounces around the screen, and red rectangle ("bump") that is stationary. The user can move the red "bump" by touching another coordinate on the screen, but that's irrelevant to this question. Each rectangle is a UIImageView (I will replace them with some kind of image/icon once I get the mechanics down). I've gotten as far as detecting when the rectangles collide, and I'm able to reverse the direction of the green "disk" on the Y axis if they do. This works well when the green "disk" approaches the red "bump" from top or bottom, it bounces off in the other direction. But when it approaches from the side, the bounce is incorrect; I need to reverse the X direction instead. Here's the timer I setup: - (void)viewDidLoad { xSpeed = 3; ySpeed = -3; gameTimer = [NSTimer scheduledTimerWithTimeInterval:0.05 target:self selector:@selector(mainGameLoop:) userInfo:nil repeats:YES]; [super viewDidLoad]; } Here's the main game loop: - (void) mainGameLoop:(NSTimer *)theTimer { disk.center = CGPointMake(disk.center.x + xSpeed, disk.center.y + ySpeed); // make sure the disk does not travel off the edges of the screen // magic number values based on size of disk's frame // startAnimating causes the image to "pulse" if (disk.center.x < 55 || disk.center.x > 265) { xSpeed = xSpeed * -1; [disk startAnimating]; } if (disk.center.y < 55 || disk.center.y > 360) { ySpeed = ySpeed * -1; [disk startAnimating]; } // check to see if the disk collides with the bump if (CGRectIntersectsRect(disk.frame, bump.frame)) { NSLog(@"Collision detected..."); if (! [disk isAnimating]) { ySpeed = ySpeed * -1; [disk startAnimating]; } } } So my question is: how can I detect whether I need to flip the X speed or the Y speed? ie: how can I calculate which edge of the bump was collided with?

  • Using physical disk with VMware Workstation

    - by chx
    I am using VMware Workstation 9.0 under Windows 7 and trying to load my Linux from Physicaldisk0. And it boots, grub sees the two partitions on the disk (I checked in command line) and the kernel and the initrd loads and then it stops saying "device not found"and drops me into an emergency shell. Indeed there is absolutely nothing in /dev not the /sda device it expects not /hda nothing that looks like a disk. Edit: I can boot the Linux disk just fine if I boot it from BIOS and not as a VM. Edit2: The question is, how can I make this setup work?

  • Virtual PC lost parent disk for differential vhd

    - by SeeR
    2 years ago I had that brilliant idea to create base Windows XP disk which all of my VM with XP will use. Of course it ended that I had only one VM with XP :-). Today I needed to make some free space on my HDD so I found one not used VM named "Windows XP" which had only 5GB. I deleted it as fast as possible :-) and of course I used shift to not use "Recycle bin". Now when I want to run my XP VM I have following error: "One of the parent hard disks of ... is missing." It's not a problem for me as soon as I can restore files from this differential vhd that I have right now. So: I have differential disk with files I need I don't have parent disk My question is: How can I restore files from this differential hvd?

  • Is it a waste of time to free resources before I exit a process?

    - by Martin
    Let's consider a fictional program that builds a linked list in the heap, and at the end of the program there is a loop that frees all the nodes, and then exits. For this case let's say the linked list is just 500K of memory, and no special space managing is required. Is that a wast of time, because the OS will do that anyway? Will there be a different behavior later? Is that different according to the OS version? I'm mainly interested in UNIX based systems, but any information will be appreciated. I had today my first lesson in OS course and I'm wondering about that now.

  • Hard Disk Spins Down as long as Battery is in Laptop

    - by Brock Dute
    Hi, I just figured out today that as long as the battery is in my laptop, it doesn't matter if it's fully charged while plugged in, Ubuntu always spins down my hard drive. I noticed this because there was a huge difference in speed when I removed the batteries. My settings for power management is basically: on AC power, don't spin down harddrive, dont suspend or anything on battery power, basically save as much power as possible I assumed that if I plug in my laptop, it'll use the On AC Power settings no matter what but apparently, this isn't so. Is there a way to "fix" this?

  • mount old ATA disk to USB adapter

    - by 213441265152351
    I am trying to recover data from an old Linux that was installed in a computer on an ATA hard drive. I found a ScanLogic USB-IDE, an ATA adapter to USB 1.0 similar to the one in the picture: and after switching it on, I plugged it into a laptop with Ubuntu 12.04. I am used to the drives being automatically mounted, but this one doesn't show up in /media. After doing a dmesg, all I got is this: [215298.671924] usb 2-1.1: new full-speed USB device number 5 using ehci_hcd [215298.767330] scsi19 : usb-storage 2-1.1:1.0 [215299.841701] usb 2-1.1: reset full-speed USB device number 5 using ehci_hcd [215300.017258] usb 2-1.1: reset full-speed USB device number 5 using ehci_hcd [215300.197050] usb 2-1.1: reset full-speed USB device number 5 using ehci_hcd [215300.372730] usb 2-1.1: reset full-speed USB device number 5 using ehci_hcd I tried plugging in the adapter to the three different USB ports in my laptop (one of them USB 3.0), but got no luck with any of them. Any ideas?

  • How difficult is it to change from Embedded programming to a high level programming [on hold]

    - by anudeep shetty
    I have a background in Computer Science. I worked on Embedded programming on Linux file systems, after I finished my Bachelor's degree, for over a year. After that I pursued my masters where most of my course choices involved working on web, java and databases. Now I have an offer to work with a company that is offering a job to work on the OS level. The company is pretty good but I am feeling that my Masters has gone to waste. I wanted to know is it common that a Computer Science major works on low-level coding and is there a possibility that I can work in this company for some years and then move onto an opportunity where I can work on high-level coding? Also is working on low-level programming a safe choice in terms of job opportunities?

  • Rail's FileStore with Linux Disk Caching or RAMdisk?

    - by Yo Ludke
    I have a Ruby on Rails application that stores it's catched files on the filesystem (Rails file-system cache). I was thinking about changing to memcached Store, but a short test shows it isn't a big difference in speed. From linuxatemyram.com I learned a bit about file caching. On the current machine there would be around 40..45GB RAM left which isn't needed for the application and which can be used to linux-disk-cache this rails file cache store. The disk is a RAID10 system with almost 120MB disk perfomance. How can I tell Linux to use free RAM more deliberately and not to be shy about using it? Do think it's necessary to adjust a sysyctl/.. value here, or would I have performance advantages to put the File Store root diretory on a ramdisk? (Loosing the cache during a reboot wouldn't be a problem)

  • Programs keep waiting for external disk to spin up - how to ignore disk?

    - by Andrew J. Brehm
    Like many Mac users I have an external Firewire disk hooked up to my Mac to be used by Time Machine. This works very well, backup-wise. The problem is that very often when I use a Mac application and try to open a file, the file selection dialogue window hangs until the external disk has spun up. I never ever want to open a file on the external disk. Sometimes this happens even when I just want to save a file I already saved (i.e. type something and press meta-s). Is there anything I can do about this?

  • Unwanted Chinese language got set in system settings

    - by Registered User
    I was discussing on the Ubuntu users list how to type in in Hindi (Indic language) in Libre Office and about a package installation problem. I have made some changes in system settings, following suggestions by some users. However, this morning when I did a reboot I am unable to see English as my default language. My system is showing some Chinese characters which I do not understand. All I wanted was to use Libre Office for a particular document in Hindi. What happened is that even Gmail is opening in Chinese. The system settings folder and others are also opening in Chinese. I am unable to use the system now. I have uploaded the snapshots here: please have a look. Upon a reboot, I was asked to rename all folders. Gmail opening in Chinese This is how menu on my system looks: half English and half Chinese Notice that in the third snapshot the calendar and menu are appearing in Chinese. I want the original US English menus and folder names back. I just wanted to type a document with Lohit Hindi font in Libre Office. I use Ubuntu 11.10. I do not use Unity, only Gnome desktop. I installed gnome-session-fallback a long time back and have been using that ever since. How do I get back to all English submenus and English folder names? I have a US English Keyboard and I use only US English. This thing which is now somehow set is unwanted.

  • Location of development solutions on disk - Common or upto the individual

    - by dreza
    In our team meeting today a senior member brought up the proposal that we should be having a common location/structure for our development solutions. A couple of his points were: Making it common meant when talking about projects and emailing stuff everyone is on the same wavelength and knows where to look. If there is ever the need to hard code a location path then it will work across all developers pc's. He had a more few points to back up his suggestion but I unfortunately got distracted during the discussion and so didn't hear all of them. I have no issue with the idea and can see it's merits but I was wondering if it is common or even recommended that all developers place their code in the same folder structure. Or do developers like to have the flexibility of location solutions where-ever they want? We currently use SVN for our version control. In this case his recommendation was to place all code in: c:\Work\Development\<Customer>\<project>\Code\<solution>\ the code I guess actual path is irrelevant for this question but added for completeness.

  • High disk time on sql-server

    - by Patrik
    Hi We have a dedicated sql-server 2008 r2 enterprise edition. The setup is: D: (data files) - stored on local ssd disks (not the same disks as log files) (raid 10) E: (log files) - stored on local ssd disks (not the same disks as data files) (raid 1) F: (transaction log backup) - stored remote on a SAN Today we moved our log files to new disks (from F: to E:). From a shared volume ( F:(SAN)) to dedicated local disks (E:). What then happend was that the "disk time", "avg. transfer time" and "avg disk write queue length" increased on the volume where we have the data files (D:) (not on the volume where the log files are located). The data volume and log volume does not share disks, however they share the same controller card. "Disk idle time" is low for all volumes. One thought is ofcourse that the controller card might be overloaded. But, we need more ideas on where the problem might be.

  • Code base migration - old versioning system to modern

    - by JohnP
    Our current code base is contained in a versioning system that is old and outdated (Visual Sourcesafe 5.0, mid 1990's), and contains a mix of packages that are no longer used, ones that are being used but no longer updated, and newer code. It is also a mix of 4 languages, and includes libraries for some of our systems (Such as Dialogic, Sun Tzu {clipper}) implementations. This breaks down into the following categories: Legacy code - No longer used (Systems that have been retired or replaced, etc) Legacy code - In current use (No intentions for upgrades or minor bug fixes, only major fixes if needed) Current code - In current use, and will be used for future versions/development Support libraries - For both legacy and current code (Some of the legacy libraries are no longer available as well) We would like to migrate this to a newer versioning system as we will be adding more developers, and expanding the reach to include remote programmers. When migrating, how do you structure it? Do you just perform a dump of all the data and then import it into the new system, or do you segregate according to type before you bring it into the new system? Do you set up a separate area for libraries, or keep them with the relevant packages? Do you separate by language, system, both? A general outline and methodology is fine, it doesn't need to be broken down to individual program level.

  • Looking for a disk manager that has options for setting allocation sizes in paritions

    - by mango
    I'm looking for a GUI program that is compatible with Ubuntu 13.10 - Server X86-64 that has all the features of Gparted but also allows for setting custom allocation sizes when creating a partition. Eg: Ability to create a 4gb Fat32 parition with 32 kilobyte allocation size. Please don't suggest a terminal only application, no matter how awesome it might be, because that's not what I asked. Wow, I come off like a right up prick when I write, eh?

  • Options for connecting an external disk to an old laptop

    - by agnul
    I've tried connecting a 2.5" external drive to an old laptop which has only USB 1. The LED on the disk lights up, but the disk doesn't seem to spin up. Since the same disk works fine on a newer laptop my guess is that the old one doesn't output enough power on the USB port. Besides looking for an external drive with its own PSU, what would you suggest? Will one of those USB cables with two connectors work? What about a powered USB hub?

  • System doesn't boot when ubuntu is installed on an SSD

    - by Caetano Nichnich Nunes
    I've recently discovered Ubuntu and decided to give it a try. I am using a Samsung Series 5 p530u3c-ad1 which comes with a 24gb SSD and a ~500gb HDD, My intention is to set the system files to the ssd and the rest to the HDD. The system works fine if I do a direct install using only the HDD, but if I try using the SSD for the system files the computer doesn't boot-up, I do not know if the SSD is being recognized by the computer, I think so because I could install Ubuntu on it, but it doesn't appear on the boot order or the boot menu. I read some posts and tried using boot-repair which pointed me not to forget to set my system to boot from my SSD, unfortunately I cannot because of the issues mentioned above. Thanks for your time.

  • What are best practices for testing programs with stochastic behavior?

    - by John Doucette
    Doing R&D work, I often find myself writing programs that have some large degree of randomness in their behavior. For example, when I work in Genetic Programming, I often write programs that generate and execute arbitrary random source code. A problem with testing such code is that bugs are often intermittent and can be very hard to reproduce. This goes beyond just setting a random seed to the same value and starting execution over. For instance, code might read a message from the kernal ring buffer, and then make conditional jumps on the message contents. Naturally, the ring buffer's state will have changed when one later attempts to reproduce the issue. Even though this behavior is a feature it can trigger other code in unexpected ways, and thus often reveals bugs that unit tests (or human testers) don't find. Are there established best practices for testing systems of this sort? If so, some references would be very helpful. If not, any other suggestions are welcome!
