• XAMPP won't start Apache on Mac OS

  - by Paul Masri

  When I try starting Apache from the XAMPP control panel (Mac OSX Snow Leopard), I get the following error popup and Apache won't start: /Applications/XAMPP/xamppfiles/bin/apachectl: line 70: ulimit: open files: cannot modify limit: Invalid argument (48)Address already in use: make_sock: could not bind to address [::]:80 XAMPP was running perfectly 10 minutes earlier. I stopped Apache to add some .conf files and it failed on restart. I removed all the new .conf files (i.e. reverted it to how it was before) but now I get the above message. EDIT: I've checked AppMonitor and I see the "httpd" processes (one by _www nested within root). Just tried quitting these but they're auto-restarted on new process IDs and it didn't solve the problem.

• Developing an Interface to a Dynamic System

  - by radix07

  I work for a small company and have been designing a GUI to interface our embedded system. The problem with this embedded system is that it is not a finished product (may never be) and is constantly under development and being tweaked and updated for different customers and applications in small volumes. So to deal with this I made a program that can export all the data from a spreadsheet where most of the embedded system variables are sourced from and throw them into a small database for the GUI application to use. This database program I made also spits out a cross reference file for the embedded system which allows the GUI to look up all the variables. This system works pretty well so far, and is even integrated with version control among the GUI, database, and embedded system. The big problem is that there is constant development on several projects that use this system and it gets terribly tedious to keep the system up to date and bring in new changes. This has gotten to the point to where I have had to code the GUI to dynamically (generically) generate all interfaces since I am never guaranteed to find the same data the same way. I have not been able to come up with a good way to uniquely identify the data I import from excel since all fields are able to be changed (due to engineering stubbornness, code re-factoring and/or excel issues) and I cannot assign a fixed reference within the sheet itself. So, are there any good methods or ideas on how to handle the chaos?

• Printer Canon MP540 succesfully added finally but doesn't print? (Attached Debug log)

  - by NES

  i tried to setup my printer in Ubuntu 10.10. I had to use special guide to install because Canon used libcupsys2 in its packages and ubuntu expects libscupsys i followed this guide in reference to this advice. The first problem was this one (the ubuntu "add printer dialog asked for root credentials". The suggested workarout in Launchpad to create a root password worked. Now i added the printer. It's available for printing. Then i got an error message "cups insecure filter" which prevented me from printing. That could be solved by setting the need root rights in the /usr/lib/cups/filter/ directory. The error message disappeared after restarting cups service. Now it should work but it doesn't. The main problem is now, the printer seems to be proper setup but when i try to print a document, the printer icon appears for short time in gnomepanel. There's a printing job in Queue which got completed, but the printer doesn't print. I attached the Debuglog provided by printer error control, had to upload to another site, since it was to big in the question body here. Perhaps someone can identify the problem with it? Note: i know that it once worked fine with an older release of Ubuntu, but not sure which version this was.

• No MAU required on a T4

  - by jsavit

  Cryptic background One of the powerful features of the T-series servers is its hardware crypto acceleration, which dramatically speeds up the compute intensive algorithms needed to encrypt and decrypt data. Previously, administrators setting up logical domains on older T-series servers had to explicitly assign crypto resources (called "MAU" for historical reasons from the T1 chip that had "modular arithmetic units") to domains that had a significant crypto workload (say, an SSL based web server). This could be an administrative burden, as you had to choose which domains got the crypto units, and issue the appropriate ldm set-mau N mydomain commands. The T4 changes things The T4 is fast. Really fast. Its clock rate and out-of-order (OOO) execution that provides the single-thread performance that T-series machines previously did not have. If you have any preconceptions about T-series performance, or SPARC in general, based on the older servers (which, it must be said, were absolutely outstanding for multi-threaded applications), those assumptions are now obsolete. The T4 provides outstanding. performance for all kinds of workload, as illustrated at https://blogs.oracle.com/bestperf. While we all focused on this (did I mention the T4 is fast?), another feature of the T4 went largely unnoticed: The T4 servers have crypto acceleration "just built in" so administrators no longer have to assign crypto accelerator units to domains - it "just happens". This is way way better since you have crypto everywhere by default without having to manage it like a discrete and limited resource. It's a feature of the processor, like doing an integer add. With T4, there is no management necessary, you just have HW crypto everywhere all the time seamlessly. This change hasn't been widely advertised, and some administrators have wondered why there were unable to assign a MAU to a domain as they did with T2 and T3 machines. The answer is that there is no longer any separate MAU, so you don't have to take any action at all - just leave the default of 0. Summary Besides being much faster than its predecessors, the T4 also integrates hardware crypto acceleration so its seamlessly available to applications, whether domains are being used or not. Administrators no longer have to control how they are allocated - it "just happens"

• Launcher sometimes appears while full screen in VM (virtaulbox) - how to stop it?

  - by frumbert

  Launcher is great, and it helps me finds stuff. I have the latest release of 12. But when I'm full screen in VirtualBox running another operating system and I hit some key combination I haven't yet figured out, Laucher suddenly grabs keyboard focus. It might be alt-tab, it might be left-control x. I have physically pulled both the windows key and FN key off my laptop because they get in the way, so it's probably not the windows key. You don't know the focus has been stolen because the full screen app (VirtualBox) is still full screen and launcher is in the background. But you're busy typing into a laucher search box, not your foreground application. This is particularly annoying. In my screenshot (taken from a camera, because the built in screen capture program can't capture a screenshot containing the launcher...) the windows VM is the foreground application, but the launcher has come up and is capturing the keyboard: http://imgur.com/SrMRr I would like a foreground full screen app to stay that way. Is there a way that I can keep the launcher but only have it activate (e.g. pop out with its search box) if I physically click the button, not type some random key combination that foreground applications can get confused about? Otherwise I can do without the launcher, because doing my actual work is more involved than just launching programs.

• Strange PHP output buffering

  - by radek-k

  PHP: header('Content-type: text/plain'); for ($i=0; $i<10; $i++){ echo "$i\r\n"; ob_flush(); flush(); sleep(1); } I tried script above on 2 different servers. Both respond numbers 0...9 in every line. In case of first server each number is received every second. In case of second server there is no output for 10 seconds and entire output is displayed at once. What might be wrong int second case? I tried various uutput control Functions but it didn't help. Set of response headers in both cases is pretty much the same: HTTP/1.1 200 OK Date: Mon, 03 Jan 2011 19:21:21 GMT Server: Apache X-Powered-By: PHP/5.2.14 Keep-Alive: timeout=15, max=100 Connection: Keep-Alive Transfer-Encoding: chunked Content-Type: text/plain

• Mysterious xyz.event files appearing

  - by Pekka

  I am getting mysterious .event files - always empty, created by me a few weeks ago - in several local project directories. They are all Subversion checkouts. They are always named after the directory they reside in, so a directory named pagination will contain a pagination.event file. Does anybody know what this is? Possibly important information: I am working on a Windows 7 Workstation I use NuSphere's PHP IDE (no updates recently) I use TortoiseSVN for version control I set up a Windows 7 backup job recently that ran once, I can' remember when exactly. The event files seem to turn up only in repositories There is no external access to those repositories

• How to set default permissions for automounted FAT drives in Ubuntu 9.10?

  - by piman

  I've got many FAT32 drives that I'd like to mount in Ubuntu such that they have permission mode 700 for directories and 600 for all other files. By default, they have 755 for all files, which is not particularly useful since almost no non-directories should be executable, and it screws up version control repos hosted on the drives. "Back in the day" I would have had the drives listed in /etc/fstab with the umask/dmask I want and there was no such thing as a default. These days, drives automount under their volume names. Which is great, except now I have no idea how to set the default. I have tried changing the /system/storage/default_options/vfat/mount_options gconf key with no apparently effect. It was 077 initially but the mounted drive reflected a default of 022; changing it and re-inserting the drives resulted in the files still having permission bits of 755.

• Mostly offsite asset management (laptops/smartphones) - what is a good SaaS based solution?

  - by Jack T

  Most of our company assets are offsite. Everyone either works at home or onsite at a customer. Most asset management/audit/remote control software concentrate on company LAN based assets. We don't need an NMS as we use OpenNMS in the internal network. I was thinking of something like Altiris Client Management Suite but since everything is connected to the internet a SaaS based solution sounds like the ways to go. LogMeIn Central looks ok but not that comprehensive. What do you guys use?

• USB Hub powers down in sleep mode on Win 7 64

  - by Andy B

  This question has been asked before but not answered. I would like the USB hub to remain on in sleep so I can wake up the laptop from an external keyboard and mouse. I have set all the device drivers by unchecking allow this device to be powered down and disabled selective suspend in control panel but the hub still powers down. If I plug a keyboard or mouse directly in to the PC they remain powered and wake the computer its only when they are connected through the hub there is a problem. I have another PC running Win 7 32. If I set this up in exactly the same way the hub remains powered in sleep. Both PC's are Toshiba Satellites with multi-core celerons but one runs Win 7 32 the other Win 7 64. BIOS settings are the same. Any help would be appreciated even confirmation that this is a feature of Win 7 64.

• Why does IIS refuse to serve ASP.NET content?

  - by Michael Haren

  My Windows Server 2003 Std server refuses to server ASP.NET content. It serves regular html just fine but anything .net, even a one line html file with an ASPX extention fails silently. Things I've tried: Nothing in the event log or IIS WWW logs when it fails. Fiddler shows no response I reinstalled .NET with C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727aspnet_regiis.exe -U C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727aspnet_regiis.exe -I I give obscenely high permissions on everything I can think of (full control, read, write, etc.) to all possibly relevant users (IUSER*, ASP.NET, etc.). I confirmed that ASP.Net v1 and v2 Web Service Extensions are "allowed" in IIS Confirmed that the Server Manager had IIS and ASP.Net roles enabled Again: this is the scenario: http://localhost/Test/Default.htm <-- Works great! http://localhost/Test/Default.aspx <-- Bombs silently with no message at all Any guidance will be much appreciated! Solution: I reinstalled per the instructions below and it works now. Thanks all!

• Choosing a JavaScript Asynch-Loader

  - by Prisoner ZERO

  I’ve been looking at various asynchronous resource-loaders and I’m not sure which one to use yet. Where I work we have disparate group-efforts whose class-modules may use different versions of jQuery (etc). As such, nested dependencies may differ, as well. I have no control over this, so this means I need to dynamically load resources which may use alternate versions of the same library. As such, here are my requirements: Load JavaScript and CSS resource files asynchronously. Manage dependency-order and nested-dependencies across versions. Detect if a resource is already loaded. Must allow for cross-domain loading (CDN's) (optional) Allow us to unload a resource. I’ve been looking at: Curl RequireJS JavaScriptMVC LABjs I might be able to fake these requirements myself by loading versions into properly-namespaced variables & using an array to track what is already loaded...but (hopefully) someone has already invented this. So my questions are: Which ones do you use? And why? Are there others that my satisfy my requirements fully? Which do you find most eloquent and easiest to work with? And why?

• Mac OS X desktop background gets reset to "Andromeda Galaxy.jpg" when users log out

  - by smokris

  I'm running Mac OS 10.6 server, and have a set of 10.6 and 10.7 workstations connected to it for authentication and MCX. Users have network profiles (home folder stored on server, via AFP). When users are logged in, they can change their desktop background. So far so good. However, the next time they log in, their desktop background has been reset to "Andromeda Galaxy.jpg". Though MCX is enabled and used to control other settings, MCX is disabled for the Desktop. What is keeping the users' desktop background from being preserved? How can I fix it?

• Using Bullet physics engine to find the moment of object contact before penetration

  - by MooMoo

  I would like to use Bullet Physics engine to simulate the objects in 3D world. One of the objects in the world will move using the position from 3D mouse control. I will call it "Mouse Object" and any object in the world as "Object A" I define the time before "mouse object" and "Object A" collide as t-1 The time "mouse object" penetrate "Object A" as t Now there is a problem about rendering the scene because when I move the mouse very fast, "Mouse object" will reside in "Object A" before "Object A" start to move. I would like the "Mouse Object" to stop right away attach to the "Object A". Also If the "Object A" move, the "Mouse object" should move following (attach) the "Object A" without stop at the first collision take place. This is what i did I find the position of the "Mouse Object" at time t-1 and time t. I will name it as pos(t-1) and pos(t) The contact time will be sometime between t-1 to t, which the time of contact I name it as t_contact, therefore the contact position (without penetration) between "Mouse object" and "Object A" will be pos(t_contact) then I create multiple "Mouse object"s using this equation pos[n] = pos(t-1) * C * ( pos(t) - pos(t-1) ) where 0 <= C <= 1 if I choose C = 0.1, 0.2, 0.3,0.4..... 1.0, I will get pos[n] for 10 values Then I test collision for all of these 10 "Mouse Objects" and choose the one that seperate between "no collision" and "collision". I feel this method is super non-efficient. I am not sure the way other people find the time-of-contact or the position-of-contact when "Object A" can move.

• Should we hire a new developer now, or wait until the code is refactored to make it suitable for a team environment?

  - by w0051977

  I support and develop a large system that uses various technologies e.g. c++,.net,vb6 etc. I am a sole developer. I am debating whether now is the right time to approach my manager (who is not a developer) to ask if another developer can be recruited. I don't have any experience working in software teams. I have always been a sole developer. The concerns I have are: There is still a lot to do. Training another developer would take time and distract me from my duties. The company does not invest heavily in tools e.g. source control The code in this system needs to be refactored to introduce concepts such as interfaces, polymorphism etc, which are supported by methodologies such as Agile (I inherited the system about 12 months ago). I am gradually trying to refactor the code. I believe I have two options: Approach my manager now Wait until I have had time to refactor the code so it is more suitable for a team environment. Which option is best? I am hoping to hear from other developers who have been in my situation.

• Interface (contract), Generics (universality), and extension methods (ease of use). Is it a right design?

  - by Saeed Neamati

  I'm trying to design a simple conversion framework based on these requirements: All developers should follow a predefined set of rules to convert from the source entity to the target entity Some overall policies should be able to be applied in a central place, without interference with developers' code Both the creation of converters and usage of converter classes should be easy To solve these problems in C# language, A thought came to my mind. I'm writing it here, though it doesn't compile at all. But let's assume that C# compiles this code: I'll create a generic interface called IConverter public interface IConverter<TSource, TTarget> where TSource : class, new() where TTarget : class, new() { TTarget Convert(TSource source); List<TTarget> Convert(List<TSource> sourceItems); } Developers would implement this interface to create converters. For example: public class PhoneToCommunicationChannelConverter : IConverter<Phone, CommunicationChannle> { public CommunicationChannel Convert(Phone phone) { // conversion logic } public List<CommunicationChannel> Convert(List<Phone> phones) { // conversion logic } } And to make the usage of this conversion class easier, imagine that we add static and this keywords to methods to turn them into Extension Methods, and use them this way: List<Phone> phones = GetPhones(); List<CommunicationChannel> channels = phones.Convert(); However, this doesn't even compile. With those requirements, I can think of some other designs, but they each lack an aspect. Either the implementation would become more difficult or chaotic and out of control, or the usage would become truly hard. Is this design right at all? What alternatives I might have to achieve those requirements?

• Outlook stopped working after updating to Windows 8

  I downloaded Windows 8 update from Microsoft's site and installed it. Everything works perfectly except Outlook. Sometimes receiving messages doesn't work for whatever reason. Now the problem is sending and replying. Before these two worked but after receiving messages started to work, these problems have occurred. When I try to press New to create a new email, I get the following error message Cannot create the e-mail message because a data file to send and receive messages cannot be found. To add a data file, such as a personal folder file, double click the Mail icon in Windows Control. When I try to reply a message, I get the following one The operation failed. An object could not be found. After the update Outlook worked ok. I've had other problems with Outlook too.

• Windows equivalent for Linux "screen" or another alternative?

  - by Ubha

  Hello all! I'm on the lookout for a method to control programs in a Windows environment. I would prefer it to be a bit similar to the Linux software "screen". The reason of my search is that I need to start a program (on Windows) with an identifier, so I later would be able to close that specific program, without closing anything else - even though the actual program (.exe file) is running multiple times. So is there anyway I can "name" it? I'm using the following on Linux now: $ screen <params> <id> ./softwareprogram And then I know I can always find it with it's ID :) It's an external program which is closing or starting a 3rd party program. My program is written in C++, if that does any difference. Thanks :)

• What methods are there to configure puppet to serve resources for multiple environments?

  - by cclark

  I seem to come across two ways for using puppet in multiple environments: 1) Install a puppetmaster in each environment and only update the recipes from source control for that environment when ready to deploy the recipes in that environment. 2) Use one puppetmaster and use a variable in the puppet.conf of each client to specify the environment and then in the puppetmaster specify a different modulepath for each environment and each of those paths is updated to the branch of the recipe repository intended for that environment (e.g. dev, staging, production). Only running one puppetmaster seems like it is one less piece of infrastructure to keep running but there is some additional complexity in the configuration. Are there additional pros or cons to one of these methods or something which I'm missing entirely?

• Which permissions need to be assigned to a normal user to allow him to change SHARE permissions?

  - by guest

  As in the subject - I am wondering, which permissions (if it is possible) do I need to assign to a regular user to modify the share permissions - e.g. to add another user with full control permissions, or to deny someone read access to the folder - on a share level. I know that this is possible through NTFS permissions, but I am wondering whether it is also possible on share level. Any ideas how to do that? Or perhaps only the adminstrator/creator/person who shared the folder has the access to this? I am using win2003 Any ideas? Thanks

• Apache Request IP Based Security

  - by connec

  I run an Apache server on my home system that I've made available over the internet as I'm not always at my home system. Naturally I don't want all my home server files public, so until now I've simply had: Order allow, deny Deny from all Allow from 127.0.0.1 in my core configuration and just Allow from all in the htaccess of any directories I wanted publicly viewable. However I've decided a better system would be to centralise all the access control and just require authentication (HTTP basic) for requests not to 127.0.0.1/localhost. Is this achievable with Apache/modules? If so how would I go about it? Cheers.

• Should sanity be a property of a programmer or a program?

  - by toplel32

  I design and implement languages, that can range from object notations to markup languages. In many cases I have considered restrictions in favor of sanity (common knowledge), like in the case of control characters in identifiers. There are two consequences to consider before doing this: It takes extra computation It narrows liberty I'm interested to learn how developers think of decisions like this. As you may know Microsoft C# is very open on the contrary. If you really want to prefix your integer as Long with 'l' instead of 'L' and so risk other developers of confusing '1' and 'l', no problem. If you want to name your variables in non-latin script so they will contrast with C#'s latin keywords, no problem. Or if you want to distribute a string over multiple lines and so break a series of indentation, no problem. It is cheap to ensure consistency with restrictions and this makes it tempting to implement. But in the case of disallowing non-latin characters (concerning the second example), it means a discredit to Unicode, because one would not take full advantage of its capacity.

• Linux and Windows machines sharing a network

  - by Saif Bechan

  I have different Windows and Linux machines that share an internal private network. From within this network I can SSH to every machine etc. This internal network works great. I have my main windows machine from where I control these machines either trough SSH or virtual desktop. Is there a way for me on my main machine to see all the machines that are connected to the network. I want to be able to see all the machines and maybe browse them, share files etc. I am very new to networking of this kind so any recommendations are welcome. Should I set up this network by workgroup? I do not think Linux supports that. Or should I set up the network with domain, I never did that before.

• SVN Active Directory authentication with ProxyPass redirect in the mix

  - by Jason B. Standing

  We have a BitNami SVN stack running on a Windows machine which holds our SVN repository. It's set up to authenticate against our AD server and uses authz to control rights. Everything works perfectly if Tortoise points at http://[machine name]/svn However - we need to be able to access it from http://[domain]/svn. The domain name points to a linux environment that we're decommissioning, but until we do, other systems on that box prevent us from just re-pointing the domain record. Currently, we've got a ProxyPass record on the linux machine to forward requests through to http://[machine name]/svn - it seems to work fine, and the endpoint machine asks for credentials, then authenticates: but when that happens, the access attempt is logged as coming from the linux box, rather than from the user who has authenticated. It's almost like some element of the credentials aren't being passed through to the endpoint machine. Has anyone done this before, or is there other info I can give to try to make sense of this problem, and figure out a way to solve it? Thankyou!
