  • Are there any MVP Frameworks projects out there?

    - by Greg Malcolm
    MVC is used a number of popular frameworks. To name just a few, Ruby on Rails, ASP.NET MVC, Monorail, Spring MVC. Are there any equivalent frameworks using any variant of MVP? Most of the examples I've found online seem to be custom implementations of the pattern rather than reusable frameworks. Suggestions need not be specific to any particular programming language, my interest is mostly academic.

  • Is giving read permissions on /etc/shadow to apache user a wise decision from security point of view?

    - by Czar
    I have to use PAM authentication for DAV SVN, but when everything is configured as specified in mod_auth_pam documentation, authentication does not work. After some research I realized, that for this to work, httpd should be running under root user (which I don't like and won't implement) or apache user (under which httpd is running by default) should have permissions to read /etc/shadow file. So there is a pair of questions connected to each other which I want to ask: Is giving this permition to apache user a wise decision from security point of view? If answer to the first question is "yes", what is the correct way to do so? For now I've done following: groupadd shadow usermod -G shadow apache chmod g+r /etc/shadow Another way I can come up with is using acl: setfacl -m u:apache:r /etc/shadow Note: OS is Fedora 14 x86_64 (kernel: 2.6.35.11) httpd v2.2.17 mod_auth_pam v1.1.1

  • Impossible to stop raid device

    - by Traroth
    I'm trying to stop a RAID disk in order to replace it by a new one, as this one is not working properly. I'm typing mdadm --stop /dev/md1, and I'm getting an error message: mdadm: fail to stop array /dev/md1: Device or resource busy I'm getting this message even if I reboot the server, and I can't see a process that could cause this. The server is working under a Debian with a 2.6.18-4-amd64 kernel. Could you help? Edit: Mote details about what my colleague tried out. After unmounting sda1, the command mdadm --remove /dev/md0 /dev/sda1 worked. But now, we still have an error message after mdadm --remove /dev/md1 /dev/sda5: mdadm: hot remove failed for /dev/sda5: Device or resource busy I still don't understand completly how the different partitions are mounted, so I suppose there is something I don't understand in the currenct situation...

  • Determining Namespaces Not in the ACPI Spec

    - by Eddie B
    I am trying to determine how it may be possible to find documentation for namespaces that are not documented in the ACPI spec. I have an Asus uEFI BIOS v(3202) and I'm receiving kernel messages stating AE Namespace lookup failures for DSSP. This is referring to a namespace that is not in the ACPI spec. I'm presuming that this is vendor specific and refers to a Digital Sensor Signal Processor. That is only a presumption. In an effort to correct ACPI errors I have dumped my DSDT using acpidump and then decompiled it using iASL. Yet to fix the error I need to know the spec on the namespace. How can I get access to the BIOS documentation that isn't part of the ACPI spec?

  • Kill xserver from command line (init 3/5 does not work)

    - by John Smith
    Hi, I'm running Linux Mint 10, although I've had this same issue with other variants of Linux. I've been told/found while researching that if the X server hangs or otherwise errors, one can drop to a root prompt, usually at another tty, and execute init 3 (to drop to single user mode) and then init 5 to return to the default, graphical session. Needless to say, I've tried this before in multiple configurations on multiple machines to no avail. The only feedback I receive form executing those two commands is a listing of VMWare services (from a kernel module) that are stopped and then restarted. Note: If I run startx (either before or after init 3), then I am told that the xserver is still running and that I should remove /tmp/.X0-lock. Having tried that, it removes that error message, but claims that the xserver cannot be attached as another instance is running. How do I kill the xserver completely? Can I killall some process name?

  • Is the recent trend toward widescreen (16:9) computer monitors a plus or minus for programmers?

    - by DanM
    It's almost gotten to the point where you can't buy a conventional (4:3) monitor anymore. Pretty much everything is widescreen. This is fine for watching movies or TV, but is it good or bad for programming? My initial thoughts on the issue are that widescreens are a net negative for programmers. Here are some of the disadvantages I see: Poor space utiliziation One disadvantage of widescreens you can't argue with is that they offer poor space utilization for the amount of total pixels you get. For example, my Thinkpad, which I bought just before the widescreen craze, has a 15" monitor with a native resolution of 1600 x 1200. The newer 15.4" Thinkpads run at most 1680 x 1050. So (if you do the math) you get fewer pixels in a wider (but not shorter) package. With desktop monitors, you pay a price in terms of desk space used. Two 1680 x 1050 monitors will simply take up more of your desk than two 1600 x 1200 monitors (assuming equal dot pitch). More scrolling If you compare a 1680 x 1050 monitor to a 1600 x 1200 monitor, you get 80 extra pixels of width but 150 fewer pixels of height. The height reduction means you lose approximately 11 lines of code. That's less you can see on the screen at one time and more scrolling you have to do. This harms productivity, maybe not dramatically, but insidiously. Less room for wide panels Widescreens also mean you lose space for wide but short panels common in programming environments. If you use Visual Studio, for example, your code window will be that much shorter when viewing the Find Results, Task List, or Error List (all of which I use frequently). This isn't to say the 80 pixels of extra width you get with widescreen would never be useful, but I tend to keep my lines of code short, so seeing more lines would be more valuable to me than seeing fewer, longer lines. What do you think? Do you agree/disagree? Are you now using one or more widescreen monitors for development? What resolution are you running on each? Do you ever miss the height of the traditional 4:3 monitor? Would you complain if your monitors were one inch narrower but two inches taller?

  • Best IDE macro tools to combat the verbosity of Java syntax for someone with carpal tunnel?

    - by Carlsberg
    I have a bad case of carpal tunnel so I'm looking for an editor that would make my Java programming less painful (literally!). Does anyone have any recommendations for tools that you can add to Eclipse, Netbeans or other IDEs to produce some of the repetitive code that's common in Java syntax? Overall what would be the best code editor for this purpose? (I'm coding on Ubuntu, in case it matters).

  • Ideas for a C/C++ library

    - by Mohit Deshpande
    I thought one of the best ways to familiarise myself with C/C++, is to make a helpful library. I was maybe thinking like a geometry library, like to calculate areas, surface area, etc. It would be useful in game programming. Or maybe an algebra library, like for different formulas like the distance formula, quadratic formula, etc. Or maybe like a standard library for very simple functions, like calculating the number of items in an array.

  • Looking for similar projects: Iphone/Android + Google Maps + "external" database = sightseeing map

    - by sniurkst
    Hello, sorry, it's not exactly a programming question, but I am currently in a research state and looking for similar projects, so I could analyze them: It should be application to iPhone or Android or other mobile platform, where, basically, user can access map with "places of interest" and add it's own "place of interest" (with photo and description). Kind of, community generated sightseeing map. I know it is quite simple and not a groundbreaking idea, but my google-fu is quite weak and I can't find anything like that.

  • Server memory issues, and expected level of service from hosting company

    - by Greg
    I'm involved in maintaining an Ubuntu VPS which runs our django websites (nginx/apache/mod_wsgi) and we've been having some memory spikes which have either caused the database to die, or induced kernel panic when the memory management system can't find any killable processes. I'm working on fixing the memory spikes, but I'm wondering whether there's anything I can do to better deal with the problem if it occurs again. Are there any tools I could use to detect the memory spikes and then, say, kill the offending process and email the server admin to fix it up? Killing off one website so that the server can remain operational is certainly preferable to the whole thing falling over. Also, we were charged $600 for after-hours service because we had to get the hosting company to restart the server - is this standard practice among hosting companies? Another provider I work with provides a panel with which I can stop and start the server myself, and given that a restart was all that was needed, $600 seems mightily excessive. (That's NZD, it's around $445 USD)

  • How do you make Windows 7 fully case-sensitive with respect to the filesystem?

    - by trusktr
    I want to make Windows 7 case-sensitive when it reads/writes anything on the hard drive (the C drive, or any other NTFS drive). I found a video via google that says to change the registry key HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\DontPrettyPath to a value of 1 (source). I also found a Windows support item that says something about modifying the registry key HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\kernel\obcaseinsensitive that leads me to assume putting a value of 0 will make Windows case-sensitive with NTFS filesystems (source). I have a feeling the second solution is the answer, but I'm not sure and I don't want to try it without being sure. Does anyone know for sure what is the correct way to make Windows 7 case-sensitive when it reads/writes to the C drive (and any other NTFS drive)?

  • What is the relationship between domNode and htmlelement?

    - by Turtle
    Hello, I am confused about the two terms. What is the difference in browser-side javascript programming? I use dojo as framework. And there is only the concept of domNode. But browser debugger always told me something as htmlelement. Are they just the same thing with different names, or with some subtle differences? Thanks.

  • RHEL raw device (over VMware RDM) performance issues

    - by jifa
    I'm running RHEL 5.3 over vSphere 4.0U1. I configured multiple LUNs on my NetApp (Fibre) storage, and added the RDM on two (Linux) VMs, using the Paravirtual SCSI adapter. One LUN is 100GB in size, successfully mapped to /dev/sdb on both VMs, 5 more are 500MB in size (mapped to /dev/sd{c-g}. I also created one partition per device. I have encountered two issues: First, writing directly to /dev/sdb1 gives me ~50MB/s, while any of the /dev/sd{c-g}1 gives me ~9MB/s. There is no difference in configuration of the LUNs apart from their size. I am wondering what causes this but this is not my main problem, as I would settle for 9 MB/s. I created raw devices using udev pretty straightforwardly: ACTION=="add", KERNEL=="sdb1", RUN+="/bin/raw /dev/raw/raw1 %N" per device Writing to any of the new raw devices dramatically slows down performance to just over 900KB/s. Can anyone point me in a helpful direction? Thanks in advance, -- jifa

  • How can I tell what script a website uses or is built with? Could it be an 'off the shelf solution'

    - by ebs
    Hi. There is an excellent website that I would like to emulate some of the characteristics of in a website that I hope to develop. (I do not intend my site being in competition with them - mine would be more of a social networking site). Can anyone tell me if it is possible to detect which script and platform is being used on www.shoutlife.com? I have very little programming or website building experience so am considering using phpfox as my solution. Thanks in advance. EBS

  • Upgrading PHP 5.1 to 5.3 on Linux Server

    - by nicorellius
    I trying to find the best way to upgrade from PHP 5.1 to 5.3. The CRM software I am running on this server requires this upgrade or else I probably wouldn't even perform it, because it seems like it's going to be perhaps trickier than I hoped it would be. Being still new to the programming world, these routine upgrades are still worrisome to me. I am running apache 2.2.6 (Fedora), PHP 5.1.6 and MySQL 5.0.27 on this server.
