• What would happen if a same file being read and appended at the same time(python programming)?

  - by Shane

  I'm writing a script using two separate thread one doing file reading operation and the other doing appending, both threads run fairly frequently. My question is, if one thread happens to read the file while the other is just in the middle of appending strings such as "This is a test" into this file, what would happen? I know if you are appending a smaller-than-buffer string, no matter how frequently you read the file in other threads, there would never be incomplete line such as "This i" appearing in your read file, I mean the os would either do: append "This is a test" - read info from the file; or: read info from the file - append "This is a test" to the file; and such would never happen: append "This i" - read info from the file - append "s a test". But if "This is a test" is big enough(assuming it's a bigger-than-buffer string), the os can't do appending job in one operation, so the appending job would be divided into two: first append "This i" to the file, then append "s a test", so in this kind of situation if I happen to read the file in the middle of the whole appending operation, would I get such result: append "This i" - read info from the file - append "s a test", which means I might read a file that includes an incomplete string?

• Is it possible to anti alias using Copy swap effect?

  - by Nor

  I'm developing an application in VB.Net using Managed DirectX that runs in windowed mode and renders onto a picture box that is smaller than the form. Whenever I resize the form, the back buffer is streched to fit the picture box. This is not what I would like. The backbuffer size is the same as screen size, however, I only want to render a part of the back buffer, whose size is controlled by the size of the picture box into which I'm rendering. Resetting the device with new presentation parameters is something I would like to avoid. I'm aware that I can use an overload of Device.Present if I set the swap effect to copy, but this doesn't allow me to use Multi Sample Anti Alias (which requires the Discard swap effect). It seems to me that the overload Device.Present is not usable with any other swap effect than copy, and throws an exception. An other alternative I considered is the PresentFlags.DeviceClip, however it seems that it works only for Windows XP. I'm using Windows 7 and it doesn't seem to be doing anything. So, is it even possible that I use anti-aliasing in this situation?

• Need help implementing this algorithm with map reduce(hadoop)

  - by Julia

  Hi all! i have algorithm that will go through a large data set read some text files and search for specific terms in those lines. I have it implemented in Java, but I didnt want to post code so that it doesnt look i am searching for someone to implement it for me, but it is true i really need a lot of help!!! This was not planned for my project, but data set turned out to be huge, so teacher told me I have to do it like this. I was reading about MapReduce and thaught that i first do the standard implementation and then it will be more/less easier to do it with mapreduce. But didnt happen, since algorithm is quite stupid and nothing special, and map reduce...i cant wrap my mind around it. So here is shortly pseudo code of my algorithm LIST termList (there is method that creates this list from lucene index) FOLDER topFolder INPUT topFolder IF it is folder and not empty list files (there are 30 sub folders inside) FOR EACH sub folder GET file "CheckedFile.txt" analyze(CheckedFile) ENDFOR END IF Method ANALYZE(CheckedFile) read CheckedFile WHILE CheckedFile has next line GET line FOR(loops through termList) GET third word from line IF third word = term from list append whole line to string buffer ENDIF ENDFOR END WHILE OUTPUT string buffer to file Also, as you can see, each time when "analyze" is called, new file has to be created, i understood that map reduce is difficult to write to many outputs??? I understand mapreduce intuition, and my example seems perfectly suited for mapreduce, but when it comes to do this, obviously I do not know enough and i am STUCK! Please please help.

• Multithreading: Read from / write to a pipe

  - by Tero Jokinen

  I write some data to a pipe - possibly lots of data and at random intervals. How to read the data from the pipe? Is this ok: in the main thread (current process) create two more threads (2, 3) the second thread writes sometimes to the pipe (and flush-es the pipe?) the 3rd thread has infinite loop which reads the pipe (and then sleeps for some time) Is this so far correct? Now, there are a few thing I don't understand: do I have to lock (mutex?) the pipe on write? IIRC, when writing to pipe and its buffer gets full, the write end will block until I read the already written data, right? How to check for read data in the pipe, not too often, not too rarely? So that the second thread wont block? Is there something like select for pipes? It is possible to set the pipe to unbuffered more or I have to flush it regularly - which one is better? Should I create one more thread, just for flushing the pipe after write? Because flush blocks as well, when the buffer is full, right? I just don't want the 1st and 2nd thread to block.... [Edit] Sorry, I thought the question is platform agnostic but just in case: I'm looking at this from Win32 perspective, possibly MinGW C...

• Testing for a closed socket

  - by Robert S. Barnes

  I'm trying to test for a closed socket that has been gracefully closed by the peer without incurring the latency hit of a double send to induce a SIGPIPE. One of the assumptions here is that the socket if closed was gracefully closed by the peer immediately after it's last write / send. Actual errors like a premature close are dealt with else where in the code. If the socket is still open, there will be 0 or more bytes data which I don't actually want to pull out of the socket buffer yet. I was thinking that I could call int ret = recv(sockfd, buf, 1, MSG_DONTWAIT | MSG_PEEK); to determine if the socket is still connected. If it's connected but there's no data in the buffer I'll get a return of -1 with errno == EAGAIN and return the sockfd for reuse. If it's been gracefully closed by the peer I'll get ret == 0 and open a new connection. I've tested this and it seems to work. However, I suspect there is a small window between when I recv the last bit of my data and when the peer FIN arrives in which I could get a false-positive EAGAIN from my test recv. Is this going to bite me, or is there a better way of doing this?

• why no implicit conversion from pointer to reference to const pointer.

  - by user316606

  I'll illustrate my question with code: #include <iostream> void PrintInt(const unsigned char*& ptr) { int data = 0; ::memcpy(&data, ptr, sizeof(data)); // advance the pointer reference. ptr += sizeof(data); std::cout << std::hex << data << " " << std::endl; } int main(int, char**) { unsigned char buffer[] = { 0x11, 0x11, 0x11, 0x11, 0x22, 0x22, 0x22, 0x22, }; /* const */ unsigned char* ptr = buffer; PrintInt(ptr); // error C2664: ... PrintInt(ptr); // error C2664: ... return 0; } When I run this code (in VS2008) I get this: error C2664: 'PrintInt' : cannot convert parameter 1 from 'unsigned char *' to 'const unsigned char *&'. If I uncomment the "const" comment it works fine. However shouldn't pointer implicitly convert into const pointer and then reference be taken? Am I wrong in expecting this to work? Thanks!

• Overlay an image over video using OpenGL ES shaders

  - by BlueVoodoo

  I am trying to understand the basic concepts of OpenGL. A week into it, I am still far from there. Once I am in glsl, I know what to do but I find getting there is the tricky bit. I am currently able to pass in video pixels which I manipulate and present. I have then been trying to add still image as an overlay. This is where I get lost. My end goal is to end up in the same fragment shader with pixel data from both my video and my still image. I imagine this means I need two textures and pass on two pixel buffers. I am currently passing the video pixels like this: glGenTextures(1, &textures[0]); //target, texture glBindTexture(GL_TEXTURE_2D, textures[0]); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE); glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, width, height, 0, GL_BGRA, GL_UNSIGNED_BYTE, buffer); Would I then repeat this process on textures[1] with the second buffer from the image? If so, do I then bind both GL_TEXTURE0 and GL_TEXTURE1? ...and would my shader look something like this? uniform sampler2D videoData; uniform sampler2D imageData; once I am in the shader? It seems no matter what combination I try, image and video always ends up being just video data in both these. Sorry for the many questions merged in here, just want to clear my many assumptions and move on. To clarify the question a bit, what do I need to do to add pixels from a still image in the process described? ("easy to understand" sample code or any types of hints would be appreciated).

• POSIX Sockets: How to detect Ctrl-C sent over Telnet?

  - by ogott

  Short Question What's the right way to handle a Ctrl-C event sent over Telnet on the server side? Long Question After calling recv() on a socket, I'd like to handle some situations appropriately. One of them is to return a certain error code when Ctrl-C was received. What's the correct way to detect this? The following works, but it just doesn't seem right: size_t recv_count; static char ctrl_c[5] = {0xff, 0xf4, 0xff, 0xfd, 0x06}; recv_count = recv(socket, buffer, buffer_size, 0); if (recv_count == sizeof(ctrl_c) && memcmp(buffer, ctrl_c, sizeof(ctrl_c) == 0) { return CTRL_C_RECEIVED; } I found a comment on Ctrl-C in a side-note in this UNIX Socket FAQ: [...] (by the way, out-of-band is often used for that ctrl-C, too). As I understand, receiving out-of-band data is done using recv() with a certain flag as the last parameter. But when I'm waiting for data using recv() as I do in the code above, I can't read out-of-band data at the same time. Apart from that, I'm getting something using recv() without that oob-flag.

• How to check if a thread is busy in C#?

  - by Sam

  I have a Windows Forms UI running on a thread, Thread1. I have another thread, Thread2, that gets tons of data via external events that needs to update the Windows UI. (It actually updates multiple UI threads.) I have a third thread, Thread3, that I use as a buffer thread between Thread1 and Thread2 so that Thread2 can continue to update other threads (via the same method). My buffer thread, Thread3, looks like this: public class ThreadBuffer { public ThreadBuffer(frmUI form, CustomArgs e) { form.Invoke((MethodInvoker)delegate { form.UpdateUI(e); }); } } What I would like to do is for my ThreadBuffer to check whether my form is currently busy doing previous updates. If it is, I'd like for it to wait until it frees up and then invoke the UpdateUI(e). I was thinking about either: a) //PseudoCode while(form==busy) { // Do nothing; } form.Invoke((MethodInvoker)delegate { form.UpdateUI(e); }); How would I check the form==busy? Also, I am not sure that this is a good approach. b) Create an event in form1 that will notify the ThreadBuffer that it is ready to process. // psuedocode List<CustomArgs> elist = new List<CustomArgs>(); public ThreadBuffer(frmUI form, CustomArgs e) { from.OnFreedUp += from_OnFreedUp(); elist.Add(e); } private form_OnFreedUp() { if (elist.count == 0) return; form.Invoke((MethodInvoker)delegate { form.UpdateUI(elist[0]); }); elist.Remove(elist[0]); } In this case, how would I write an event that will notify that the form is free? and c) an other ideas?

• BSOD Dump - EXCEPTION_DOUBLE_FAULT - ON Windows 2008 Server 64bit

  - by Mark K

  Hello, my windows 2008 server (datacenter ed) 64bit , have recently created a series of BSOD on a different applications. the error message is in general EXCEPTION_DOUBLE_FAULT. Can anyone please help with the analysis of the dump file bellow- Best regards, Mark 2: kd !analyze -v * Bugcheck Analysis * * UNEXPECTED_KERNEL_MODE_TRAP (7f) This means a trap occurred in kernel mode, and it's a trap of a kind that the kernel isn't allowed to have/catch (bound trap) or that is always instant death (double fault). The first number in the bugcheck params is the number of the trap (8 = double fault, etc) Consult an Intel x86 family manual to learn more about what these traps are. Here is a portion of those codes: If kv shows a taskGate use .tss on the part before the colon, then kv. Else if kv shows a trapframe use .trap on that value Else .trap on the appropriate frame will show where the trap was taken (on x86, this will be the ebp that goes with the procedure KiTrap) Endif kb will then show the corrected stack.

  I have a VCD with 22 minutes of video on it. I would like to retain this footage and throw away the VCD. I can play the whole thing with VLC ("open disc - vcd - /dev/sr0 - play"): all 22 minutes of the main track. I don't believe there's any other content aside from the main track. I can seek to anywhere I want to within the 22 minute track. If I mount /dev/sr0 /media/vcd and then try to copy the only file from the MPEGAV folder, I get an I/O error, with an empty destination file. VLC has a "convert" option in addition to "play". When I use this I actually get a good OGG file back, after it runs through the video in painful real-time. I guess it dubs it frame-by-frame. But the file is only 10 minutes long, leaving 12 minutes off of the track. Handbrake doesn't detect it's track titles, unfortunately. I don't know if I should start getting involved with GNU ddrescue or if it's because VCDs somehow encode their data sectors differently. Anyway, I'm in way over my head and if anyone knows how I could get that video track off the thing, feel free to share! Edit: I should note that I also have access to a Windows computer

• How do I tell ubuntu to send traffic to a single IP through eth6?

  - by flashnode

  I want to ensure that all IP traffic going to 172.16.60.62 uses eth6. Please provide complete commands because my linux-fu is rusty. The host is running Ubuntu Precise 12.04 user@host:~$ ifconfig eth3 eth3 Link encap:Ethernet HWaddr 00:e0:81:72:fe:c9 inet addr:172.16.60.122 Bcast:172.16.60.255 Mask:255.255.255.0 inet6 addr: fe80::2e0:81ff:fe72:fec9/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:128500 errors:0 dropped:0 overruns:0 frame:0 TX packets:29082 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:67524823 (67.5 MB) TX bytes:2217634 (2.2 MB) Interrupt:71 Base address:0x6000 user@host:~$ ifconfig eth6 eth6 Link encap:Ethernet HWaddr 00:60:dd:47:81:35 inet addr:172.16.60.61 Bcast:172.16.60.255 Mask:255.255.255.0 inet6 addr: fe80::260:ddff:fe47:8135/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:9000 Metric:1 RX packets:109610 errors:0 dropped:0 overruns:0 frame:0 TX packets:109388 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:10785630 (10.7 MB) TX bytes:10754350 (10.7 MB) Interrupt:70 user@host:~$ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 172.16.60.1 0.0.0.0 UG 0 0 0 eth3 169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 eth6 172.16.60.0 0.0.0.0 255.255.255.0 U 1 0 0 eth6 172.16.60.0 0.0.0.0 255.255.255.0 U 1 0 0 eth3

• Toshiba Satellite U500 - Totally Damaged LCD

  - by ivan

  I accidentally damaged my Toshiba Satellite U500 laptop which resulted in a totally unusable LCD. The LCD panel has some cracks on it, and I can only see black & white spots; the laptop frame became broken/bent to where I can partially see inside the PC; the accident disassembled the CD tray, and bent the keyboard frame (which now has a weird hump). The system is still working though. It responds to my inputs (eg, turning it on/off, typing my password @ Windows Login, etc). What I want to do now is to transfer all of my important data from that laptop to my external drive. But I don't know how since the LCD screen is unreadable. I know I can connect it to an external monitor or a TV (I have a Samsung 1080p TV) but I don't know how. What cable should I purchase to connect the TV? Which ports on the laptop and TV should I connect it to? Do I need press something while/after connecting it? Can I boot my laptop using the TV?

• How can find the USB wireless adapter into the dmesg log file?

  - by AndreaNobili

  I am pretty new in Linux (RaspBian for RaspBerry Pi but I think that there are not difference) and I have to install an USB wireless network adapter (the product is the TP-Link TL-WN725N, this one: http://www.tp-link.it/products/details/?model=TL-WN725N ) Now, I think that this is not automatically recognized by my system because if I execute ifconfig command I obtain the following output: pi@raspberrypi ~ $ ifconfig eth0 Link encap:Ethernet HWaddr b8:27:eb:2a:9f:b0 inet addr:192.168.1.8 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:475 errors:0 dropped:0 overruns:0 frame:0 TX packets:424 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:34195 (33.3 KiB) TX bytes:89578 (87.4 KiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) So now it see only my ethernet network interface and not the wireless. So I was thinkig to try to see into the dmesg, but I don't know what have I to see and how to select it into the dmesg output. For example by the following command I can see the line of the dmesg log file relate to my ethernet port: pi@raspberrypi ~ $ cat /var/log/dmesg |grep -i eth [ 3.177620] smsc95xx 1-1.1:1.0 eth0: register 'smsc95xx' at usb-bcm2708_usb-1.1, smsc95xx USB 2.0 Ethernet, b8:27:eb:2a:9f:b0 [ 18.030389] smsc95xx 1-1.1:1.0 eth0: hardware isn't capable of remote wakeup [ 19.642167] smsc95xx 1-1.1:1.0 eth0: link up, 100Mbps, full-duplex, lpa 0x45E1 But what can I try to search for the USB wireless adapter? Tnx

• PDF to HTML - batch converter - most reliable and accurate free AND paid for software?

  - by therobyouknow

  I'm look for either a free or paid-for (about 50$/40pounds) BATCH PDF to HTML converter to convert several PDF files at once. Needs to be able to handle vectored and bitmap images within the file, outputting both as jpegs referenced by the html pages. I've tried iorigsoft paid-for PDF to HTML - problems it seems to hang or just go idle, and the stuff it actually converts have broken links - the wrong name is used for constituent chapters as html. Also tried application from intrapdf.com but this crashes near the beginning of the conversion, consitently. Update: intrapdf works on my Windows XP machine but not on my Windows 7 machine. The only glitch is with the framed index contents html - the graphics in the page do not display in the page in the frame - but if you open the frame only in a new tab then you can see them. That might be a browser glitch in chrome only. This solution is good enough for me - given that I've already spent the money (I had spent before I asked) but I can't accept my own answer as this does not work on Windows 7. Looked at opensource tools but they look equally flakey or use old PDF versions. Need it on Windows 7 32bit home. Thoughts?

• ping/ssh networking problem with server from 1 particular windows xp laptop

  - by user47650

  I am experiencing an odd problem with one specific server at my data centre connecting from my laptop. Basically the server is accessible from other machines in my house, but not from 1 particular laptop which is running windows XP. I have setup tcpdump on the server and wireshark on the laptop, and I can see ping echo request and reply packets that actually make it back to the wireshark on the laptop, but nothing shows in the ping console output like so; $ ping xxx.55.32.255 Pinging xxx.55.32.255 with 32 bytes of data: Request timed out. Request timed out. Request timed out. Request timed out. Ping statistics for xxx.55.32.255: Packets: Sent = 4, Received = 0, Lost = 4 (100% loss), But I can see from the wireshark on my local laptop that the ping reply gets back... No. Time Source Destination Protocol Info 46 3.964474 192.168.1.64 xxx.55.32.255 ICMP Echo (ping) request Frame 46 (74 bytes on wire, 74 bytes captured) Ethernet II, Src: Intel_31:d3:01 (00:19:d2:42:c3:01), Dst: ThomsonT_01:b8:2c (00:14:7f:02:b9:3c) Internet Protocol, Src: 192.168.1.64 (192.168.1.64), Dst: xxx.55.32.255 (xxx.55.32.255) Internet Control Message Protocol No. Time Source Destination Protocol Info 48 4.119060 xxx.55.32.255 192.168.1.64 ICMP Echo (ping) reply Frame 48 (74 bytes on wire, 74 bytes captured) Ethernet II, Src: ThomsonT_01:b8:2c (00:14:7f:01:b8:2c), Dst: Intel_21:c3:01 (10:20:d2:31:c3:01) Internet Protocol, Src: xxx.55.32.255 (xxx.55.32.255), Dst: 192.168.1.64 (192.168.1.64) Internet Control Message Protocol obviously I have disabled the windows firewall and there is nothing in the windows event log. There is nothing else obviously strange about the server as it is the same build as other servers that I can connect to fine.
