• Remote desktop connection over internet without port forwarding?

  - by hellbell.myopenid.com

  Hello, let's say that we have this situation. I want to remote desktop connection to my friend over the internet, but I don't have premission for port forwarding on the router, and my friend also can't configure his router. So the question is how to connect to computer without port forwarding, I know that is out there some programs like teamviewer, or some else that solve that task, but what I looking for is the some free site that can make "bridge" between are two computer, or is it possible to install on computer some program that simulate virtual router or something like this http://www.youtube.com/watch?v=SIof7kFTgJE .... I need this cause I have my own simple remote desktop connection program, but I can't connect to other computer outside network cause don't have premission to configure router :( any comment, link, advice, or tutorials will be very helpful :)

• How do I debug a cluster running Microsoft server 2003?

  - by alcor

  I'm sole developer of a complex critical software system, written in Visual C++ 2005. It's deployed on a classical Microsoft cluster scenario (active/passive), that has Windows Server 2003 R2. If a server A goes down, the other one (B) starts and take the ownership of its duties. You have to know that: Both servers have the same Microsoft patches/fixes, same hardware, same everything. Both servers use the same memory storage (a RAID-6 through fiber channel). This software has a main module that launches the peripheral modules. if a peripheral module crashes, the main module restarts it. When I switch the application in one of the two servers (let's say the B server) two of the peripheral modules of the main applications just started to crash apparently without reason about 2 seconds after the start of the peripheral module. What could I do to analyze/inspect/resolve this weird situation?

• determine the archetecture of a mac from the command line or script?

  - by Brian Postow

  I'm writing a shell script, and I need to know the archetecture, ie PPC or Intel. Back in the day, there was a program /bin/arch that told you, but my mac doesn't seem to have it... Is there an easy way I can do this? Grep for something in a logfile? call some other program that spits that out as a side effect? It would be nice to know what OS Version I'm running too, but that may not be necessary. thanks

• Compilation problem [closed]

  - by Misery

  I am trying to compile a program called Triangle Mesh Generator. It is an open source code written in ANSI C. I need it to bo a callable lib so I am using a switch (#define) created by it's Author. However I get this error: /usr/lib/gcc/x86_64-linux-gnu/4.6/../../../x86_64-linux-gnu/crt1.o: In function `_start': collect2: ld returned 1 exit status make: *** [triangle] Error 1 I am not sure why such an error occurs. Worth adding is that compiling it as a stand alone program is succesful. I am using GCC on 12.04. The lines quoted above constitute the total output. What I put in the terminal is just make in the proper folder. There are no other errors, warnings, or other messages. Link to the sources I found some additional instructions. I'll get back after reading them :] EDIT: I have found some additional instructions that let me compile it. Thanks for help. I am closing question right now. Regards

• i18n and L10n (1)

  - by Aaron Li

  Internationalization (i18n) is a way of designing and developing a software product to function in multiple locales. This process involves identifying the locales that must be supported, designing features which support those locales, and writing code that functions equally well in any of the supported locales. Localization (L10n) is a process of modifying or adapting a software product to fit the requirements of a particular locale. This process includes (but may not be limited to) translating the user interface, documentation and packaging, changing dialog box geometries, customizing features (if necessary), and testing the translated product to ensure that it still works (at least as well as the original). i18n is a pre-requisite for L10n. Resource is 1. any part of a program which can appear to the user or be changed or configured by the user. 2. any piece of the program's data, as opposed to its code. Core product is the language independent portion of a software product (as distinct from any particular localized version of that product - including the English language version). Sometimes, however, this term is used to refer to the English product as opposed to other localizations.   Useful links http://www.mozilla.org/docs/refList/i18n/ http://www.w3.org/International/ http://hub.opensolaris.org/bin/view/Community+Group+int_localization/

• How can i compare Audio, what programming language should i use

  - by Pimmetje

  I have 2 audio files that are from almost the same source. But at some points there shifted a bit. Also the codecs does not match. I would like to make a program that takes a sample 2 - 4 seconds. And looks for it in the other file. (Most of the time it's not shifted more than 30 seconds). Than take the time and store it, Go ahead for a few seconds take a sample and find it again. This way i want to create a file where i can see on what points the file is shifted. For people who are more interested in what i want. I have a audio/video file speech and subtitles. But i have same speech from different sources with differs a bit in time. And i like to make a program that can correct the subtitle time for me. Enough about the problem I looked on the Internet for ways to compare audio files. Based on what i read comparing 2 audio files isn't that easy as i had hoped. Some talk about algorithms http://www.perlmonks.org/?node_id=169641 Some audio-library's portaudio.com aubio.org sourceforge.net/projects/ccaudio/ ambiera.com/irrklang/ The biggest problem i have is that i can't find something i can generate from the audio that i can use to compare with. I hope someone here can point me in the right direction.

• Why do the Nouveau drivers work better than the Nvidia ones?

  - by user50774

  I have a bit of a weirdie here. My rig uses an Nvidia GeForce 8600 GTS in a PCIE x16 slot. Up to about a year ago, no problems with the card. I then started getting random crashes. They got more frequent. Now, first thought: It's an old card. But I don't have the bucks to buy a new one, and my mobo doesn't have the DVI input that my monitor needs. So, I decided to take a shot with the Nouveau drives. Amazingly, they have worked flawlessly. Does anyone have a guess as to why?

• Massive crash and kernel panic after updates yesterday, what now?

  - by Ghost

  Got 12.04 on an AMD+radeon machine, everything was running fine until last night when the update manager installed new packages, and now the moment I open a browser (firefox, chromium, anything) it crashes instantly. It says warning: at build/buildd/linux-3.5.0/arch/x86/kernel/smp.c:123 native_smp_send_reschedule+0x5b/0x60() Pid: 2432, comm: chrome_dbthread tainted: G D 3.5.0-2generic #2-ubuntu I already tried uninstalling the packages from the update log, didn't solve a thing. Depending of which browser I use I get a different reaction, like a complete freeze instead of a text console crash. Ideas? I really don't know what to do.

• Most efficient way to store this collection of moduli and remainders?

  - by Bryan

  I have a huge collection of different moduli and associated with each modulus a fairly large list of remainders. I want to store these values so that I can efficiently determine whether an integer is equivalent to any one of the remainders with respect to any of the moduli (it doesn't matter which, I just want a true/false return). I thought about storing these values as a linked-list of balanced binary trees, but I was wondering if there is a better way? EDIT Perhaps a little more detail would be helpful. As for the size of this structure, it will be holding about 10s of thousands of (prime-1) moduli and associated to each modulus will be a variable amount of remainders. Most moduli will only have one or two remainders associated to it, but a very rare few will have a couple hundred associated to it. This is part of a larger program which handles numbers with a couple thousand (decimal) digits. This program will benefit more from this table being as large as possible and being able to be searched quickly. Here's a small part of the dataset where the moduli are in parentheses and the remainders are comma separated: (46) k = 20 (58) k = 15, 44 (70) k = 57 (102) k = 36, 87 (106) k = 66 (156) k = 20, 59, 98, 137 (190) k = 11, 30, 68, 87, 125, 144, 182 (430) k = 234 (520) k = 152, 282 (576) k = 2, 11, 20, 29, 38, 47, 56, 65, 74, ...(add 9 each time), 569 I had said that the moduli were prime, but I was wrong they are each one below a prime.

• Free batch image watermarking software

  - by Blade

  Hi everyone. I'm looking for a simple yet effective software to watermark a lot of photos in batch. I have to apply a transparent png watermark image on 400 photos. The program have to place the watermark at a custom position relative to the bottom right corner of every picture. I would have done this in photoshop, but the scriptable action doesn't allow me to do conditionnal placing if the photo is portrait or landscape. I'm looking for a free lightweigh program. Thank you !

• Basic questions while making a toy calculator

  - by Jwan622

  I am making a calculator to better understand how to program and I had a question about the following lines of code: I wanted to make my equals sign with this C# code: private void btnEquals_Click(object sender, EventArgs e) { if (plusButtonClicked == true) { total2 = total1 + Convert.ToDouble(txtDisplay.Text); //double.Parse(txtDisplay.Text); } else if (minusButtonClicked == { total2 = total1 - double.Parse(txtDisplay.Text) } } txtDisplay.Text = total2.ToString(); total1 = 0; However, my friend said this way of writing code was superior, with changes in the minus sign. private void btnEquals_Click(object sender, EventArgs e) { if (plusButtonClicked == true) { total2 = total1 + Convert.ToDouble(txtDisplay.Text); //double.Parse(txtDisplay.Text); } else if (minusButtonClicked == true) { double d1; if(double.TryParse(txtDisplay.Text, out d1)) { total2 = total1 - d1; } } txtDisplay.Text = total2.ToString(); total1 = 0; My questions: 1) What does the "out d1" section of this minus sign code mean? 2) My assumption here is that the "TryParse" code results in fewer systems crashes? If I just use "Double.Parse" and I don't put anything in the textbox, the program will crash sometimes right?

• Guidelines for creating referentially transparent callables

  - by max

  In some cases, I want to use referentially transparent callables while coding in Python. My goals are to help with handling concurrency, memoization, unit testing, and verification of code correctness. I want to write down clear rules for myself and other developers to follow that would ensure referential transparency. I don't mind that Python won't enforce any rules - we trust ourselves to follow them. Note that we never modify functions or methods in place (i.e., by hacking into the bytecode). Would the following make sense? A callable object c of class C will be referentially transparent if: Whenever the returned value of c(...) depends on any instance attributes, global variables, or disk files, such attributes, variables, and files must not change for the duration of the program execution; the only exception is that instance attributes may be changed during instance initialization. When c(...) is executed, no modifications to the program state occur that may affect the behavior of any object accessed through its "public interface" (as defined by us). If we don't put any restrictions on what "public interface" includes, then rule #2 becomes: When c(...) is executed, no objects are modified that are visible outside the scope of c.__call__. Note: I unsuccessfully tried to ask this question on SO, but I'm hoping it's more appropriate to this site.

• MDT Image Hierarchy

  - by Antix

  Just a quick question, I couldn't find this out by looking around and have not had the time to run a test myself: Is it possible to create image hierarchies in MDT? Take this example where we have three images. - Image 1: Base OS - Image 2: Company Wide Applications (built off Image 1) - Image 3: Specific Role Applications (built off Image 2) Now just say we change the version of an application in Image 2. The next time we build Image 3, will this take the new version of the application since it's basing its image off Image 2? Also, If we add a program to Image 1, leave Image 2 unchanged and re-build Image 3, would this include the new program? I'm trying to plan out a way of creating images such that if a change is required for an image that is on basically every machine (think, Image 1) then we only have to change it in one location. Has anyone actually done something like this and has any tips?

• Where to find current information on quality of released games as software products?

  - by Tom

  As a gamer, one thing I have learned I need to be savvy about is knowing whether SomeBigGame is actually unstable or otherwise problematic as a piece of software (riddled with invasive DRM products, only runs well on a particular video driver version, crashes on non-English-language systems, etc.). I know that game news media can sometimes be relied upon to report on some problems, but I doubt they bother to cover smaller or indie titles. An example: I've started playing Transformice on Kongregate, and I'm considering installing the downloadable client (it is an online multiplayer game). The part of me that cares about data privacy and maintaining a clean-and-healthy PC wants to know whether there is a place I can check to find out more about a title-as-software than "it is not a literal virus." Put another way: where would you not want to see your game receive lots of attention?

• Pointers inside a structure [on hold]

  - by user3402552

  I have the next program: #include<stdio.h> #include<stdlib.h> struct a { char *ch; char *str; }; int main() { struct a s1; char ptr[100]; int m, n; printf("\n Enter a string : "); gets(ptr); m = strlen(ptr); s1.ch = (char *)malloc(strlen(ptr) * sizeof(char)); if(s1.ch) { strcpy(s1.ch, ptr); } else { printf("\n Alocation failed!\n"); } printf("\n %s\n\n", s1.ch); while(*s1.ch) { printf(" %c", *(s1.ch)); s1.ch++; } printf("\n\n"); s1.ch = s1.ch - m; printf("\n\n\n %s \n\n", s1.ch); } Is this ok this program in this way ? I mean the pointers should not be initialized ? And if it is not ok, why compile it without errors?

• Powershell window preventing shutdown

  - by FrinkTheBrave

  If I have a PowerShell window (at the PS command prompt) on display it prevents the computer shutting down. i.e. if I open a powershell window and then try to shutdown the server, I get the End Program popup saying Windows cannot end this program I get the same result if I start the powershell from the start menu, from a cmd prompt and from a shortcut with -NoExit specified. Any ideas how I can get shutdown to automatically close a powershell window (if it is at the PS prompt) in the same way as it would for a CMD window? Alternatively, is it possible for PowerShell to detect when a shutdown has been initiated and therefore close itself?

• Game programming : C# or C++?

  - by Chronix

  Ok so the faq says : "What language should I learn next? (Unless you have a specific requirement and don't know which language meets that requirement.)" so I guess this is not against the rules of questions. So, I've decided what I really want is to do Game Programming. So the question is, as a 18 years old who wants to learn self taught programming, what is the most suited programming language between C# and C++? ( I should state that I don't care about unix because I believe windows will be still the most used os ) I know the basics of C++, but none about C#. I know that C++ has more tutorials guides, dlls and stuff like that, while C# doesn't, but it's far easier to learn and to use for a single person to develop a program, but I've read even if the program is obfuscated it's easy to get the source of it. Well, I kinda want to focus on basic a lot first, I must say that I have a preference for C++ just because it feels more suitable to me, but I must consider that I work alone.. So even if I like it, it may not be the best thing to do. I am really not sure of which one to go for, i've read a lot of threads on various websites and it looks like C# is becoming more popular than C++. But yeah, that said, I also specified I want to do Game Programming. So I need to know some better points than just "C# is easier because of .net memory handling while C++ isnt" because I couldn't just find it. I hope the thread won't be closed because I've read the faq and I have a specific requirement. Thank you, and if you need more details you're free to ask me, but I think just by saying game programming and that I'd work alone should be enough!

• Why does Scala require functions to have explicit return type?

  - by garbage collection

  I recently began learning to program in Scala, and it's been fun so far. I really like the ability to declare functions within another function which just seems to intuitive thing to do. One pet peeve I have about Scala is the fact that Scala requires explicit return type in its functions. And I feel like this hinders on expressiveness of the language. Also it's just difficult to program with that requirement. Maybe it's because I come from Javascript and Ruby comfort zone. But for a language like Scala which will have tons of connected functions in an application, I cannot conceive how I brainstorm in my head exactly what type the particular function I am writing should return with recursions after recursions. This requirement of explicit return type declaration on functions, do not bother me for languages like Java and C++. Recursions in Java and C++, when they did happen, often were dealt with 2 to 3 functions max. Never several functions chained up together like Scala. So I guess I'm wondering if there is a good reason why Scala should have the requirement of functions having explicit return type?

• Does Windows 8 support the "start in [folder]" property for shortcuts?

  - by FumbleFingers

  I use Foobar2000 to play music, and for years now I've run it in what they call "portable mode". What that means is that the program itself isn't actually "installed" in the traditional Windows sense. All "non-system" dll's required by the application are in the same folder as the executable; earlier versions of Windows find them there, and everything runs fine. But Windows 8 fails because it doesn't find them. I want things set up this way because I keep Foobar2000 on a portable external hard drive, so I can just move it between different computers without having to go through the Windows install process. With all previous versions of Windows, I could either directly run the application from File Explorer, or create a shortcut on the desktop with the "start in folder" property set to the actual folder containing the program. I can still use the first method, but I want a shortcut! Is there any way to do what I want?

• Ubuntu 14.04 LTS AMD64 randomly uninstals packages / applications

  - by Jacob Lindeen

  I am having a strange issue. Occasionally when installing new packages, I will get a system crash notification which I will report. The environment then becomes unstable, unity crashes and all open windows, loose title bars, and the main launcher shuts down. I usually have to run the command unity --replace to restore functionality, but ultimately end up having to reboot. Upon booting back up I find all of my user-installed packages are gone and I have to reinstall them via apt. Please tell me someone else is having this issue, because this is the second system and third install I have had this issue on.
