  • UML enumeration as a return type

    - by Ryan Fernandes
    << enumeration>> E1 | .RED .GREEN .BLUE | I have the above as an enumeration class in a UML diagram. I associate it with another class say House. I now need a method on House say +getColor() which returns a color from the above enumeration. How would I depict this in UML? would it be like : +getColor(): E1 ?

  • 2d Vector with wrong values

    - by Petris Rodrigo Fernandes
    I'm studing STL, then i thought "i'll make a 2d array!" but whatever... a coded this: vector< vector<int> > vetor; vetor.resize(10); vetor[0].resize(10); for(int i = 0; i < vetor.capacity(); i++){ for(int h = 0; h < vetor[0].capacity();h++){ vetor[i][h] = h; } } Until here, ok. But when i try to show the array value a use this: for(int i = 0; i < vetor.capacity(); i++){ cout << "LINE " << i << ": "; for(int h = 0; h < vetor[0].capacity();h++){ cout << vetor[i][h] <<" "; } cout << "\n"; } And the results are really wrong: LINE 0: 4 5 6 7 8 9 6 7 8 9 LINE 1: 0 1 2 3 0 1 2 3 0 1 LINE 2: 0 1 2 3 0 1 2 3 0 1 LINE 3: 0 1 2 3 0 1 2 3 0 1 LINE 4: 0 1 2 3 0 1 2 3 0 1 LINE 5: 0 1 2 3 0 1 2 3 0 1 LINE 6: 0 1 2 3 0 1 2 3 0 1 LINE 7: 0 1 2 3 0 1 2 3 0 1 LINE 8: 0 1 2 3 0 1 2 3 4 5 LINE 9: 0 1 2 3 4 5 6 7 8 9 What's happening with my program? it isn't printing the right values!

  • Why can't I project ToString() in VB?

    - by Martinho Fernandes
    If you try to compile the query below in Visual Basic .NET, it fails. From x In {1, 2} Select x.ToString() The error given by the compiler is: Range variable name cannot match the name of a member of the 'Object' class. There is nothing wrong with the equivalent C# query, though: from x in new[]{1, 2} select x.ToString() This does not happen with the ToString overload that takes a format (it is a member of Int32, not Object). It does happen with other members of Object, as long as they don't take an argument: with GetType and GetHashCode it fails; with Equals(object) it compiles. Why is this restriction in place, and what alternatives can I use?

  • What encoding does c32rtomb convert to?

    - by R. Martinho Fernandes
    The functions c32rtomb and mbrtoc32 from <cuchar>/<uchar.h> are described in the C Unicode TR (draft) as performing conversions between UTF-321 and "multibyte characters". (...) If s is not a null pointer, the c32rtomb function determines the number of bytes needed to represent the multibyte character that corresponds to the wide character given by c32 (including any shift sequences), and stores the multibyte character representation in the array whose first element is pointed to by s. (...) What is this "multibyte character representation"? I'm actually interested in the behaviour of the following program: #include <cassert> #include <cuchar> #include <string> int main() { std::u32string u32 = U"this is a wide string"; std::string narrow = "this is a wide string"; std::string converted(1000, '\0'); char* ptr = &converted[0]; std::mbstate_t state {}; for(auto u : u32) { ptr += std::c32rtomb(ptr, u, &state); } converted.resize(ptr - &converted[0]); assert(converted == narrow); } Is the assertion in it guaranteed to hold1? 1 Working under the assumption that __STDC_UTF_32__ is defined.

  • Disable work offline in Internet Explorer 8

    - by Roberto Liffredo
    I am using Windows 7, and IE8. Every time I have GMail open in IE8, and I resume from sleep, I get the question about working offline - even if at that momoent the wireless connection is available. This is particularly sad, because all browsing is stopped until I dismiss that dialog, that may be hidden below other windows. As I am not using offline browsing at all, is it possible to disable the functionality altogether, so that I no longer get the question? A bit like in Firefox, where I simply get the error message with page unavailable. I have googled a bit, but no luck so far. Even a direct modification of the registry would be fine, for me.

  • Router slowing my connection?

    - by Roberto
    I have a Linksys WRT54G and I pay for a 12Mbps connection. I've been testing my connection using speedtest.net for many days and always get 8Mbps. I called the support and they told me to bypass the router and test. I did it and got 16Mbps (much more than I pay for), so I thought "this guy just changed my speed so can he blame my router", and he blamed it. But to my surprise, everytime I bypass the router I get 16Mbps and when I use the router I get 8Mbps. Is this guy trolling me somehow (configuring the VOIP-modem-stuff to different profiles depending o the MAC address connecting to it) or is my router a POS? How can I find out? I don't know what's the thing the router connects to, it's a kind of VOIP adapter; the link is this one, but unfortunately I don't think you'll understand because it's in Portuguese. I know they can remotely connect to it, that's the origin of my conspiracy theory :) I just tested wired to the router and got 10Mbps (and still 8Mbps on wifi and 16Mbps without router) O_o I'm 5cm away from my router, so no obstacles to interfere, right? ------ UPDATE ------- It's a WRT54G V8, I'm using firmware v8.00.7 (will install 8.00.8 tomorrow, but I saw that it's only a minor fix to UPnP denial of service security vulnerability). Results: IPerf LAN-LAN: 80Mbps IPerf LAN-WLAN: 19Mbps (therefore we can ignore wireless issues/settings) I wasn't able to make the (W)LAN-WAN NAT-enabled test with IPerf, I get a connection refused error. I'm not sure if did it right: ran in server mode, configured router to forward that port to my IP and tried to connect to my internet IP that got from this site. I don't think there is a way to disable NAT using this firmware. Question: Let's suppose it's an underpowered hardware issue. Is it right to assume that custom firmwares could resolve the issue because they are possibly better implemented and would make better use of the router resources? I couldn't find any references pointing to wired performance improvements with the use of custom firmware.

  • Alsa devices under Wine

    - by Roberto Aloi
    Hi all, I'm running OpenSuse 11.2 and Wine 1.1.28. Even if audio is perfectly working fine for me (Skype, Banshee, etc), when I try to configure audio for Wine (to use Spotify) I cannot hear anything from the audio test. In the winecfg audio tab, ALSA is checked, but no devices are available. I tried to run alsaconf (it needs root permissions) but it returns: No supported PnP or PCI card found No legacy drivers available, either. Any idea?

  • Remote Desktop Client Crashes following domain join

    - by Roberto Charlie Ciarleglio
    I recently joined my laptop to our windows domain and now the remote desktop client crashes when i try and connect to any machine. It works if I run as administrator but not ordinarily. The domain join migrated my local profile to the domain profile which i think is where the problem lies. I'm guessing its a permission thing as I had a similar problem with dropbox and had to delete reg keys and reinstall. I can't figure out how to fix this problem though. The event viewer shows this: Faulting application name: mstsc.exe, version: 6.1.7601.17514, time stamp: 0x4ce7ab44 Faulting module name: FACredProv2.dll, version: 2.4.95.1, time stamp: 0x4bb8d766 Exception code: 0xc0000005 Fault offset: 0x00000000000025b2 Faulting process id: 0xb24 Faulting application start time: 0x01cd43fbd3a81fba Faulting application path: C:\Windows\System32\mstsc.exe Faulting module path: C:\Windows\System32\FACredProv2.dll Report Id: 154ee55a-afef-11e1-a443-b8ac6f704c5d any help would be appreciated!

  • Is my HDD dead forever?

    - by Roberto
    Yesterday I turned on my computer and it couldn't boot. I found out the hd (320GB SATA Seagate Momentus 7200.3 for notebook) was broken and it couldn't be recognized by the BIOS. I have another of the same hard drive, so I exchanged the boards. I found out that there is a problem on its board since my good hard drive didn't work. But the broken hard drive doesn't work with the good board as well: it can be recognized but when I insert a Windows Instalation DVD it says the hard drive is 0GB. I put it in a case and use it in another computer via USB, and but it doesn't show up in the "My Computer". I used a software to recover files called "GetDataBack for NTFS", it recognized the hard drive but with the wrong size (2TB). I try to make it read the hard drive but it got an I/O error reading sector. It tries to read, the hard drive spins up. So, since I'm using a good board on it, the problem seems to be internal. Is there anything someone could do to recover the files from it?

  • Tunneling traffic through two VPN hops/tunnels.

    - by Roberto Sebestyen
    I am a web developer, and I find myself often working from home. But when I do, I am forced to Remote Desktop to the Office desktop computer and work from there. The reason is because the application I am working on needs to connect to servers at a Data Center via a VPN from the Office Desktop. HomeDesktop (Win7) --- PVN --- OfficeDesktop(WinXP) --- VPN --- Data Center What I would really like to do is, I would like to find a way to be using my Home desktop developing on that, and whenever my computer tries to access servers on the Data Center, I would like to tunnel that traffic through the two VPN tunnels separating me and the Data Center. I have admin privileges on both Office Desktop and Home Desktop, but I do not have any admin privileges in the Data Center. So what kind of tunneling solution could I use here? Is it even possible?

  • Using Automator to click on an Application-specific button

    - by Roberto Aloi
    I'm new to Automator. I need to launch a specific application and to click on one of its buttons. I've used the "Watch Me Do" feature to register the button click but, in the Automator events log, this action is being reported as "Bring the window XXX to the front." I'm then wondering if a better way exists to "record" a button-click. The reason behind my question is linked to this: http://superuser.com/questions/148386/mac-running-an-automator-task-at-night In fact, using the "Watch me do" approach, Automator is apparently not able to perform the click action when the machine is on sleep and a password is required. Any help would be much appreciated. Thanks.

  • Tiling Windows on Mac

    - by Roberto Aloi
    What is your favourite free Tiling Window Manager for Mac? Open Source would be a plus, but it's not required. NOTE: I know about Expose', but it doesn't "tile" the windows as far as I know (but I would be glad to be corrected).

  • Running an Automator task at night

    - by Roberto Aloi
    I've just created an Automator workflow and I'm using crontab to execute it at night. The problem is that, after a while, the machine is going to sleep and a password is required (this is the intended behaviour). Unfortunately, Automator seems to be unable to perform the task when the password is required. It works like a charm if the "password required" dialog is not displayed (before the sleep). Any suggestion on how to solve this?

  • How to host many websites using same public IP address but different domains.

    - by Roberto Sebestyen
    I know how to configure one IIS instance to run many websites using the same public ip address, but different domain names (As long as I have control over the domains). But how can you configure many IIS servers running on different virtual machines in the same network, to host websites using the same public IP addres, but different domain names? Normailly in IIS under the website you can set the headers to which the website will respond to. but what if that website is on a different machine?

  • Unusable Source for Ubuntu image on Xen 3

    - by Roberto Aloi
    Hi all, I'm trying to create a new VM in Xen 3, running Ubuntu 10.4 (32 bit) as the guest OS. Xen 3 is installed on a machine running OpenSuse 11.2. I downloaded the Ubuntu image from the ubuntu.com website and I mounted it on /dev/loop0. When I try to create the new VM in Xen with the given source, Xen complains the "source is unusable". I've also checked the md5 sum for the image. It's fine. Any suggestion or hint that could help me?

  • Automating the insertion of credits in video files on Mac OS X

    - by Roberto Aloi
    I have a bunch of video files (mp4). I need to insert some title information at the beginning and some credits at the end. I'm currently using iMovie. Since the title could be extracted from the filename and the credits are always the same, I'm wondering how could I make all this process as automatic as possible. I was thinking about Automator, but I'm open to any other solution. iMovie is the preferred tool so far, but I could use anything else (as far as it doesn't require additional licensing/cost). Any idea?

  • LXC, Port forwarding and iptables

    - by Roberto Aloi
    I have a LXC container (10.0.3.2) running on a host. A service is running inside the container on port 7000. From the host (10.0.3.1, lxcbr0), I can reach the service: $ telnet 10.0.3.2 7000 Trying 10.0.3.2... Connected to 10.0.3.2. Escape character is '^]'. I'd love to make the service running inside the container accessible to the outer world. Therefore, I want to forward port 7002 on the host to port 7000 on the container: iptables -t nat -A PREROUTING -p tcp --dport 7002 -j DNAT --to 10.0.3.2:7000 Which results in (iptables -t nat -L): DNAT tcp -- anywhere anywhere tcp dpt:afs3-prserver to:10.0.3.2:7000 Still, I cannot access the service from the host using the forwarded port: $ telnet 10.0.3.1 7002 Trying 10.0.3.1... telnet: Unable to connect to remote host: Connection refused I feel like I'm missing something stupid here. What things should I check? What's a good strategy to debug these situations? For completeness, here is how iptables are set on the host: iptables -F iptables -F -t nat iptables -F -t mangle iptables -X iptables -P INPUT DROP iptables -P FORWARD ACCEPT iptables -P OUTPUT ACCEPT iptables -A INPUT -p tcp --dport 22 -j ACCEPT iptables -A INPUT -p icmp --icmp-type echo-request -j ACCEPT iptables -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE iptables -t nat -A POSTROUTING -o lxcbr0 -j MASQUERADE iptables -t nat -A PREROUTING -p tcp --dport 7002 -j DNAT --to 10.0.3.2:7000

  • How to avoid copying corrupted files with rsync

    - by Roberto Aloi
    I have an HDD with plenty of files, some of which are unfortunately corrupted. I'm now trying to copy the good files into a new HDD. I'm using: rsync -azP SRC TGT When rsync comes to one of the corrupted files, I can see a message in the console: rsync: read errors mapping XXX: Input/output error (5) In the target folder, I still see the corrupted file, which I'm not able to open and which I have to delete manually. Is there any option to tell rsync not to copy files after a i/o error?

  • Make a drive from one machine appear as a physical disk in another machine.

    - by Roberto Sebestyen
    I want to take a physical disk (or part of a disk) in one machine (call it machine-A) and I want to make it available in another machine (machine-B). But I don't want to map a network drive. I want it to appear in machine-B as a physical drive. Even though it is not a physical drive. The reason I want to do this is i want the ability to create shares in machine-B on that drive. Since I cannot do that on mapped drives, I need to use some utility that fools machine-B to think that it is a physical drive, and treat it as such. Both of these machines are windows server 2003. I heard about NFS, It sounds like what could be the solution to my problem. But isn't that a Linux/Unix protocol? What tools can I use to make this happen? Are there any open source solutions? I don't care what the solution is, as long as it achieves the end result, preferably open source solution though. Thanks for reading guys and gals!
