  • Sound from Ubuntu Server 10.04

    - by emilyk
    I feel like this should be a no brainer, but I just can't seem to figure it out. I am running Ubuntu Server 10.04 as a virtual machine in VMWare Fusion. I am simply trying to get there to be some sound that comes out of my laptop speakers. I have installed Alsa and MOC (followed these instructions, and it worked fine http://howto.blbosti.com/2010/03/ubuntu-server-install-alsa-sound-and-moc-music-on-console/). Especially using MOC, I can see that the song (an MP3) is playing, but I am not getting any sound out. lspci | grep audio gives me: 02:02.0 Multimedia audio controller: Ensoniq ES1371 [AudioPCI-97] (rev 02) This doesn't seem like it should be that big of a deal, but I just can't seem to make it work. Any ideas?

  • ubuntu 12.04 sound not working in applications

    - by user109887
    I run Ubuntu on a DELL Vostro 3500 laptop. Everything was working perfectly since this morning, after an update... I can't play any multimedia sound anymore, that includes youtube and others, mp3 in Rythmbox, sound of video in VLC. I can see my device in the setting window and I can play tests sound, but nothing else. Any idea? EDIT: I'm switching very often from to HDMI output, which is deconnected right now. I've tried running VLC, and in the audio menu, you can choose the output so now I can listen to music via VLC but not with other programs. Looks like ubuntu is not totally switching the audio device after unplugging the HDMI cable. Is there any command line which can do so?

  • Improving python code

    - by cobie
    I just answered the question on project euler about finding circular primes below 1 million using python. My solution is below. I was able to reduce the running time of the solution from 9 seconds to about 3 seconds. I would like to see what else can be done to the code to reduce its running time further. This is strictly for educational purposes and for fun. import math import time def getPrimes(n): """returns set of all primes below n""" non_primes = [j for j in range(4, n, 2)] # 2 covers all even numbers for i in range(3, n, 2): non_primes.extend([j for j in range(i*2, n, i)]) return set([i for i in range(2, n)]) - set(non_primes) def getCircularPrimes(n): primes = getPrimes(n) is_circ = [] for prime in primes: prime_str = str(prime) iter_count = len(prime_str) - 1 rotated_num = [] while iter_count > 0: prime_str = prime_str[1:] + prime_str[:1] rotated_num.append(int(prime_str)) iter_count -= 1 if primes >= set(rotated_num): is_circ.append(prime) return len(is_circ)

  • How to access parent window in dialog

    - by Bruce
    I am using Quickly and created the main window and a dialog. In the main window I am setting access to database (u1db) in the finish_initializing method (self.db=...). After an action I open a dialog where I need access to the database. I thought that I can use self.get_parent() in the dialog to get instance of the main window and access the database, but return value of the get_parent() is None. My question is, how can I access the instance of the parent window in the dialog or perhaps where should I place the instance of the database wrapper? Shortened code: class GuitestWindow(Window): def finish_initializing(self, builder): ... self.db = u1db.open( db_path, create=True ) def on_addaccountbutton_clicked(self, widget): dialog = NewAccountDialog.NewAccountDialog() result = dialog.run() dialog.hide()

  • 12.04 precise HDMI not working on ATI Radeon

    - by sfxpt
    This is precisely a 12.04 HDMI output problem, because it works for 11.10 - everything else are the same, only the OS version is different. The symptom is that on my HDMI output TV screen, it always shows Unsupported resolution even after setting it to the resolution that works on Ubuntu 11.10 (via gnome-control-center, in which it detects my TV just fine), I still don't see any output on TV. The audio is not working either. I think it is 12.04's problem, because if I boot into Ubuntu 11.10, and everything else remain the same, HDMI output (video & audio) work just fine. 12.04 is a freshly installed, just the vanilla Ubuntu HD installation. How should I nailed down / fix the problem?

  • FreeBSD performance tuning. Sysctls, loader.conf, kernel

    - by SaveTheRbtz
    I wanted to share knowledge of tuning FreeBSD via sysctl.conf/loader.conf/KENCONF. It was initially based on Igor Sysoev's (author of nginx) presentation about FreeBSD tuning up to 100,000-200,000 active connections. Tunings are for FreeBSD-CURRENT. Since 7.2 amd64 some of them are tuned well by default. Prior 7.0 some of them are boot only (set via /boot/loader.conf) or does not exist at all. sysctl.conf: # No zero mapping feature # May break wine # (There are also reports about broken samba3) #security.bsd.map_at_zero=0 # If you have really busy webserver with apache13 you may run out of processes #kern.maxproc=10000 # Same for servers with apache2 / Pound #kern.threads.max_threads_per_proc=4096 # Max. backlog size kern.ipc.somaxconn=4096 # Shared memory // 7.2+ can use shared memory > 2Gb kern.ipc.shmmax=2147483648 # Sockets kern.ipc.maxsockets=204800 # Can cause this on older kernels: # http://old.nabble.com/Significant-performance-regression-for-increased-maxsockbuf-on-8.0-RELEASE-tt26745981.html#a26745981 ) kern.ipc.maxsockbuf=10485760 # Mbuf 2k clusters (on amd64 7.2+ 25600 is default) # For such high value vm.kmem_size must be increased to 3G kern.ipc.nmbclusters=262144 # Jumbo pagesize(_SC_PAGESIZE) clusters # Used as general packet storage for jumbo frames # can be monitored via `netstat -m` #kern.ipc.nmbjumbop=262144 # Jumbo 9k/16k clusters # If you are using them #kern.ipc.nmbjumbo9=65536 #kern.ipc.nmbjumbo16=32768 # For lower latency you can decrease scheduler's maximum time slice # default: stathz/10 (~ 13) #kern.sched.slice=1 # Increase max command-line length showed in `ps` (e.g for Tomcat/Java) # Default is PAGE_SIZE / 16 or 256 on x86 # This avoids commands to be presented as [executable] in `ps` # For more info see: http://www.freebsd.org/cgi/query-pr.cgi?pr=120749 kern.ps_arg_cache_limit=4096 # Every socket is a file, so increase them kern.maxfiles=204800 kern.maxfilesperproc=200000 kern.maxvnodes=200000 # On some systems HPET is almost 2 times faster than default ACPI-fast # Useful on systems with lots of clock_gettime / gettimeofday calls # See http://old.nabble.com/ACPI-fast-default-timecounter,-but-HPET-83--faster-td23248172.html # After revision 222222 HPET became default: http://svnweb.freebsd.org/base?view=revision&revision=222222 kern.timecounter.hardware=HPET # Small receive space, only usable on http-server, on file server this # should be increased to 65535 or even more #net.inet.tcp.recvspace=8192 # This is useful on Fat-Long-Pipes #net.inet.tcp.recvbuf_max=10485760 #net.inet.tcp.recvbuf_inc=65535 # Small send space is useful for http servers that serve small files # Autotuned since 7.x net.inet.tcp.sendspace=16384 # This is useful on Fat-Long-Pipes #net.inet.tcp.sendbuf_max=10485760 #net.inet.tcp.sendbuf_inc=65535 # Turn off receive autotuning # You can play with it. #net.inet.tcp.recvbuf_auto=0 #net.inet.tcp.sendbuf_auto=0 # This should be enabled if you going to use big spaces (>64k) # Also timestamp field is useful when using syncookies net.inet.tcp.rfc1323=1 # Turn this off on high-speed, lossless connections (LAN 1Gbit+) # If you set it there is no need in TCP_NODELAY sockopt (see man tcp) net.inet.tcp.delayed_ack=0 # This feature is useful if you are serving data over modems, Gigabit Ethernet, # or even high speed WAN links (or any other link with a high bandwidth delay product), # especially if you are also using window scaling or have configured a large send window. # Automatically disables on small RTT ( http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/netinet/tcp_subr.c?#rev1.237 ) # This sysctl was removed in 10-CURRENT: # See: http://www.mail-archive.com/[email protected]/msg06178.html #net.inet.tcp.inflight.enable=0 # TCP slowstart algorithm tunings # We assuming we have very fast clients #net.inet.tcp.slowstart_flightsize=100 #net.inet.tcp.local_slowstart_flightsize=100 # Disable randomizing of ports to avoid false RST # Before usage check SA here www.bsdcan.org/2006/papers/ImprovingTCPIP.pdf # (it's also says that port randomization auto-disables at some conn.rates, but I didn't checked it thou) #net.inet.ip.portrange.randomized=0 # Increase portrange # For outgoing connections only.

I wanted to thank FreeBSD community, especially author of nginx - Igor Sysoev, nginx-ru@ and FreeBSD-performance@ mailing lists for providing useful information about FreeBSD tuning. FreeBSD WIP * Whats cooking for FreeBSD 7? * Whats cooking for FreeBSD 8? * Whats cooking for FreeBSD 9? So here is the question: What tunings are you using on yours FreeBSD servers? You can also post your /etc/sysctl.conf, /boot/loader.conf, kernel options, etc with description of its' meaning (do not copy-paste from sysctl -d). Don't forget to specify server type (web, smb, gateway, etc) Let's share experience!

  • Yet again: "This device can perform faster" (Samsung Galaxy Tab 2)

    - by Mike C
    I've been doing a lot of research with no reasonable solution. Please excuse the length of my post. When I plug my Galaxy Tab 2 (7" / Wi-Fi only / Android ICS) into my Windows 7 64-bit machine, I (almost always) get this warning popup that "This device can perform faster." And in fact, transfers onto the Tab in this mode are slow. The two times I've been able to get a high-speed connection, the transfer has occurred at the expected speed. I just don't know what to do to get that high-speed transfer. (The first time I did, it was the first time I connected the Tab; the second time I did, I was fiddling around and unplugging/plugging in again.) That popup is telling me that the device is USB2, but that it thinks I've connected to a USB1 port. In fact, every USB port (there are ten) on this system is USB2. It's an ASUS M3A78-EMH mobo from late 2008. I'm not sure what the chipset is; the CPU is an AMD Athlon 4850e, but I've seen this message reported for non-AMD systems. (Every mobo reference I've seen in reports on this has been for Asus, but of course most reporters aren't reporting that info at all.) The Windows 7 installation is just a couple weeks old (I had a disk crash) but I saw the same warning on the WinXP/64 that was installed previously. In Device Manager, there are two "Standard Enhanced PCI to USB Host Controller" nodes which are the actual high-speed controllers. There are also five "Standard OpenHCD USB Host Controller" nodes, which I have determined are virtual USB1 controllers embedded in the "Enhanced" controllers. (In Device Manager, I'm using View|Devices by Connection.) My high-speed thumb drives, external disks, and iPod all show up as subnodes of the "Enhanced" controllers; the keyboard, mouse, and USB speakers under the "OpenHCD" ones -- and this is true no matter which ports these devices are plugged into. The Tab shows up under an OpenHCD node, unsurprisingly. It appears as a threesome: a top-level "Mobile USB Composite device" with two subs: "Galaxy Tab 2" and "Mobile USB Modem." (I have no idea what the modem device implies or how I might use it, but I don't care about it either: I just want the Tab to reliably connect at high speed.) On the Tab, the USB support has a switch between PTP and MTP, the latter being the default, and the preferred mode for me (as I'm usually hooking it up for music synch). I have tried, however, connecting it as PTP, and it still connects as USB 1. (As PTP, only the "Galaxy Tab 2" device appears -- no Composite, no Modem.) If it's plugged in as MTP and I change the setting to PTP, Windows unloads and reloads the device, and voila: The Tab appears under an "Enhanced" node, but eventually re-loads again to show a exclamation icon on the device; Properties then shows "This device cannot start." Same response if I plug it in as PTP and then change to MTP; in this case, only the Tab itself shows the exclamation, not the other two devices. One thing I have not tried, and really would prefer to avoid, is installing the "beta" chipset driver available on the Asus website, which is dated 2009. Windows tells me it has the most up-to-date drivers for the Tab, and for the chipset, and I'm inclined to believe that. I suspect the problem is with the Samsung drivers, or possibly the hardware. One suggestion I saw elsewhere which might, possibly, pertain is to ensure the USB cable is properly shielded; however, the Tab has one of those misbegotten 30-pin, not-quite-an-iPod connectors; I don't know if I could find a 3rd party one. It seems unlikely that this cable is improperly shielded, tho. (Is there a way to test that?) So, my question is: does anyone know how to get this working as one might reasonably expect it to?

  • SQL SERVER – DMV – sys.dm_os_wait_stats Explanation – Wait Type – Day 3 of 28

    - by pinaldave
    The key Dynamic Management View (DMV) that helps us to understand wait stats is sys.dm_os_wait_stats; this DMV gives us all the information that we need to know regarding wait stats. However, the interpretation is left to us. This is a challenge as understanding wait stats can often be quite tricky. Anyway, we will cover few wait stats in one of the future articles. Today we will go over the basic understanding of the DMV. The Official Book OnLine Reference for DMV is over here: sys.dm_os_wait_stats. I suggest you all to refer this for all the accuracy. Following is a statement from the online book: “Specific types of wait times during query execution can indicate bottlenecks or stall points within the query. Similarly, high wait times, or wait counts server wide can indicate bottlenecks or hot spots in interaction query interactions within the server instance.” This is the statement which has inspired me to write this series. Let us first run the following statement from DMV. SELECT * FROM sys.dm_os_wait_stats ORDER BY wait_time_ms DESC GO Above statement will show us few of the columns. Here it is quick explanation of each of the column. wait_type – this is the name of the wait type. There can be three different kinds of wait types – resource, queue and external. waiting_tasks_count – this incremental counter is a good indication of frequent the wait is happening. If this number is very high, it is good indication for us to investigate that particular wait type. It is quite possible that the wait time is considerably low, but the frequency of the wait is much high. wait_time_ms – this is total wait accumulated for any type of wait. This is the total wait time and includes singal_wait_time_ms. max_wait_time_ms – this indicates the maximum wait type ever occurred for that particular wait type. Using this, one can estimate the intensity of the wait type in past. Again, it is not necessary that this max wait time will occur every time; so do not over invest yourself here. signal_wait_time_ms – this is the wait time when thread is marked as runnable and it gets to the running state. If the runnable queue is very long, you will find that this wait time becomes high. Additionally, please note that this DMV does not show current wait type or wait stats. This is cumulative view of the all the wait stats since server (instance) restarted or wait stats have been cleared. In future blog post, we will also cover two more DMVs which can be helpful to identify wait-related issues. ?sys.dm_os_waiting_tasks sys.dm_exec_requests Reference: Pinal Dave (http://blog.SQLAuthority.com) Filed under: Pinal Dave, PostADay, SQL, SQL Authority, SQL DMV, SQL Query, SQL Scripts, SQL Server, SQL Tips and Tricks, SQL Wait Stats, SQL Wait Types, T SQL, Technology

  • Big Data: Size isn’t everything

    - by Simon Elliston Ball
    Big Data has a big problem; it’s the word “Big”. These days, a quick Google search will uncover terabytes of negative opinion about the futility of relying on huge volumes of data to produce magical, meaningful insight. There are also many clichéd but correct assertions about the difficulties of correlation versus causation, in massive data sets. In reading some of these pieces, I begin to understand how climatologists must feel when people complain ironically about “global warming” during snowfall. Big Data has a name problem. There is a lot more to it than size. Shape, Speed, and…err…Veracity are also key elements (now I understand why Gartner and the gang went with V’s instead of S’s). The need to handle data of different shapes (Variety) is not new. Data developers have always had to mold strange-shaped data into our reporting systems, integrating with semi-structured sources, and even straying into full-text searching. However, what we lacked was an easy way to add semi-structured and unstructured data to our arsenal. New “Big Data” tools such as MongoDB, and other NoSQL (Not Only SQL) databases, or a graph database like Neo4J, fill this gap. Still, to many, they simply introduce noise to the clean signal that is their sensibly normalized data structures. What about speed (Velocity)? It’s not just high frequency trading that generates data faster than a single system can handle. Many other applications need to make trade-offs that traditional databases won’t, in order to cope with high data insert speeds, or to extract quickly the required information from data streams. Unfortunately, many people equate Big Data with the Hadoop platform, whose batch driven queries and job processing queues have little to do with “velocity”. StreamInsight, Esper and Tibco BusinessEvents are examples of Big Data tools designed to handle high-velocity data streams. Again, the name doesn’t do the discipline of Big Data any favors. Ultimately, though, does analyzing fast moving data produce insights as useful as the ones we get through a more considered approach, enabled by traditional BI? Finally, we have Veracity and Value. In many ways, these additions to the classic Volume, Velocity and Variety trio acknowledge the criticism that without high-quality data and genuinely valuable outputs then data, big or otherwise, is worthless. As a discipline, Big Data has recognized this, and data quality and cleaning tools are starting to appear to support it. Rather than simply decrying the irrelevance of Volume, we need as a profession to focus how to improve Veracity and Value. Perhaps we should just declare the ‘Big’ silent, embrace these new data tools and help develop better practices for their use, just as we did the good old RDBMS? What does Big Data mean to you? Which V gives your business the most pain, or the most value? Do you see these new tools as a useful addition to the BI toolbox, or are they just enabling a dangerous trend to find ghosts in the noise?

  • BSOD Before Windows Will Loads - Graphics Related

    - by Brian
    Alright deep breath here: (Windows 7 Home Premium 64 bit btw) Today I installed Star Craft 2 Beta. After trying to log in, it had some issues where it said my device stopped working (referring to my video device I have to imagine). After I force quit the game there were some random "hot" (various colors if i remember correctly) pixels on the screen. I decided to reboot and try again with similar results. I figured that maybe my display drivers could stand to be updated (I don't frequently update them as I don't often run into problems). I went out to nVidia's website and grabbed the latest drivers for Windows 7 64 bit GeForce 9 series. (I have SLi-ed 9800 GTs). Everything seemed to install fine and I performed the restart. This is when things went from bad (can't play SC2 beta ;) ) to worse (can't boot into windows!). Initially the very first splash screen - I think it's the bios splash screen - had lines of colored pixels covering it. It then displayed a screen that had lots of "(" on it. After that it showed the normal windows 7 splash screen as if it were going to load into Windows. Before getting much further, it BSODed on me. It was a 0x0000003B stop error. At nvlddmkm.sys. A little digging let verified that this was a problem with an nVidia graphics device, not a real shocker. Windows decided it would try to help me diagnose the problem, which it's only answer to was a System Restore, which did nothing to alleviate the problem. I was able to boot up fine in safe mode and was not able to roll back the driver, however I did uninstall the driver and reboot. I still had the graphical anomalies during the first two screens (same colored "."'s and weird "("'s), but there was NOT a stop error. Windows loaded up, found a default driver for the device and installed it and I restarted to let it load - and had yet another BSOD Stop error. Repeat driver uninstall, this time I reloaded the same version (I think it's possible that I was running a 32 bit version or a vista versus windows 7 version, but I don't have that information handy) of the nVidia driver from their website. Restart, same anomalies, same Stop Error. I am at a loss - At this point all I can think is that the firmware for the Video cards got fried or there's actual damage to the cards which I sincerely hope is not the case but the sooner I know the better. Any insight into what I might be able to do to troubleshoot/fix this problem would be most helpful. Attached below is a dump from DxDiag.

  • How to speed up a HP M9517C

    - by Jen
    I bought a system with 8GB RAM, 1TB HD, Quad-Core AMD Phenom 9550, Nvidia Geforce 9300GE, 64-bit Windows Vista Machine. Bought it primarily because it was cheap and came with 25.5 inch screen. Problem: It's slow - if you can believe it. My Dell laptop 1525 is faster and more stable! I tried installing and dual-booting Linux Mint and ran into video and audio troubles. I need fast and stable and I'm going for awesome. Anyone have some suggestions on making this thing smoking hot? Vista is fine, but slows over time - suspect virus/spyware/etc.. But I need to use Photoshop, Fireworks, Dreamweaver, Illustrator. I've tried the alternatives and I just don't like them. When you've got deadlines looming you want to work with what you know. Also use Skype (and I had audio problems with it in Linux), gotomeeting, gotowebinar. Don't need MS Office. Tried VMWare, Virtualbox and again - I keep getting audio/video problems. I'd love someone's input on THEIR setup and how they got there. I'm sure I need to upgrade my video card, but what should I go to?

  • How to setup equivalent USVIDEO.ORG DNS-Proxy on Linux

    - by Gary
    I have a VPS in the USA running Ubuntu. I want to setup something similar to http://www.usvideo.org Basically, USVIDEO is a DNS service that allows Canadians to access American content like Hulu, Netflix, NBC, and etc (restricted by geographical IP). Here is how I think USVideo does it: Clients (PS3, XBOX, PC) specifies the DNS server(s) as specified on USVIDEO.org's website. If the DNS request is a video/audio site such as Netflix or Pandora, forward the request to a proxy. Otherwise, for all other requests, forward it to a different DNS server. If the specific video/audio URL is requested, return the address of the proxy server, which in turn relays traffic to the destination video/audio domain via the U.S. gateway so that it appears that the access is coming from a U.S. IP address. Once the DNS request has passed the U.S. IP address check, their proxy server steps out of the loop and lets the video streaming site contact you directly to start the video stream. This trick relies on the way that the video streaming sites check the country of your IP address once up front, but don't actually check the country of the destination IP address while the video is streaming. What is elegant about this solution is that a VPN Tunnel is not required to bypass geographical IP checks from certain websites. All that is required on the client side is to specify the DNS server (the VPS). If a certain site is geographically locked, just forward the traffic to a proxy, and that's it. These sites can be specified in the DNS entries, or perhaps in the proxy service to redirect the DNS request to its own proxy. I believe what I need to setup something similar is Squid Proxy, IPTables, and DNS. What I need help is how to exactly approach this? Would Squid Proxy be setup as a transparent proxy?

    - by Sergiy Byelozyorov
    I have recently bought Philips SHB6110. Extract from the 13th page of manual: Therefore you can connect your Bluetooth stereo headset. with a Bluetooth stereo enabled phone to both listen to music and lead calls, or with a Bluetooth phone that does not support Bluetooth stereo (A2DP) to lead calls and at the same time to a Bluetooth audio device (Bluetooth enabled MP3 player, Bluetooth audio adapter etc.) to listen to music. Make sure to pair the phone first with your Bluetooth headset, then turn both the phone and headset off to then pair the Bluetooth audio device. With the SwitchStream feature you can listen to music and monitor your calls at the same time. Even while listening to music, you will hear a ring tone when receiving a call and can switch to the call simply by tapping the button. The manual however doesn't specify how do I connect to both device at the same time. I use Toshiba Satellite Pro P300-1CG laptop with Belkin Mini Bluetooth Adapter and Nokia N95 phone. Operating system is Windows 7 64-bit and I have Skype installed. Both phone and compute can be used for listening to music and talking on the phone (on PC via Skype). Best solution would be if I could connect to PC and phone as the same time and monitor calls both mobile and Skype calls while listening music from Winamp. If that is not possible, then I would like at least to be able to listen music from PC, while monitoring calls from mobile. So, please tell me how do I connect both PC and phone to headphones?

  • Recording screen-casts on another computer

    - by paleozogt
    We're trying to record the desktops of users using demo versions of our software (this is an in-house lab setup). We need to have the recording happen on a separate computer (just across the room), so that the recording software doesn't interfere with the user. Every screen recording software I've seen will only record what's happening on the computer its installed on; ie, you can't record what's happening on another computer. So it seems I need to cobble together a solution (unless anyone knows of software that will do this). Getting the video to the other computer seems easy enough. I'm using TightVNC with the DFMirage driver on the test computer. The recording computer connects to the test computer with TightVNC and then uses CamStudio to record what's happening. The real problem is how to deal with the audio. We need to record both what the user is saying (through a headset mic) as well as the sounds produced by the test computer. But VNC doesn't transmit audio. :( I'm not sure how to get both audio streams (mic and sounds) over to the recording computer. Any ideas?

  • Burn .srt subtitles to AVC encoded video (transcoding with hardsubs) [closed]

    - by Saxtus
    Possible Duplicate: How do I hard code a movie with subtitles? I am looking for a software (or combination of software) that will allow me to hard burn subtitles from an .srt file, that has italics and bold typefaces, to an H.264/AVC encoded video so it can played from a desktop player that can't display external subtitles correctly. Ideally it could use Directshow as input as DirectVobSub makes nice job showing the subtitles as they should (allowing me to globally adjust font and size). CUDA use, to speed up encoding, will be great but not necessary. Video source is also H.264/AVC encoded. Audio is AC-3 5.1 and should be retained too but I have no problem re-muxin it later as long as it keeps synced. Until now I've unsuccessfully tested: Avisynth 2.58 Unable to make Direcvobsub to launch through it TextSub() command renders subtitles with fixed font/size and doesn't decode tags Malformed audio TMPGEnc 4.0 XPress 4.7.4.299 Audio downmixed to 2.0 Importing of subtitles doesn't decode tags Badaboom 1.2.1.7 No importing of subtitles at all SUPER © 2010.build.37 "Directshow decode" has similar effect as Avisynth above Other modes doesn't appear to allow any subtitles in Thank you.

  • How can I wipe my iPod classic and fix any bad sectors on the hard drive without killing it?

    - by Sam Meldrum
    My iPod never finishes syncing and only syncs audio, not pictures or video - any ideas as to how I can fix it? My iPod classic 160GB worked well for a couple of years. I used to sync a lot of photos at full resolution to it, but this recently stopped working after I moved to Windows 7. iTunes is on latest version - 9.1.1.12 iPod software is up to date - 1.1.2 Windows 7 is fully up to date and patched The symptoms are that the iPod will start to sync, all audio (music and podcasts will sync successfully) but the syncing will then just appear to continue - itunes message: Syncing iPod. Do not Disconnect. This sync never completes - I have left it trying for days. I have tried resetting the iPod using the Restore button, whereupon it restarts sync from default options and again will sync audio, but nothing else. I suspect that something has gone wrong on the hard-drive - either a bad sector or some corrupt data. Is there a process I can go through to fix this? E.g. SpinRite or a format? If so how do I go about formatting an iPod and will it be recognised as an iPod after format and work as normal? Any advice on what to try next much appreciated? Update I have eliminated problems with the files, PC or iTunes as they sync fine to other iPods. I have also eliminated the cable by trying different cables which work with other iPods. What I'd really like to know is if there is any way to more fundamentally wipe the iPod safely, attempt to repair any bad sectors on the hard drive and then start from scratch. Anyone ever managed this?

  • HD video editing system with Truecrypt

    - by Rob
    I'm looking to do hi-def video editing and transcoding on an unencrypted standard partition, with Truecrypt on the system partition for sensitive data. I'm aiming to keep certain data private but still have performance where needed. Goals: Maximum, unimpacted, performance possible for hi-def video editing, encryption of video not required Encrypt system partition, using Truecrypt, for web/email privacy, etc. in the event of loss In other words I want to selectively encrypt the hard drive - i.e. make the system partition encrypted but not impact the original maximum performance that would be available to me for hi-def/HD video editing. The thinking is to use an unencrypted partition for the video and set up video applications to point at that. Assuming that they would use that partition only for their workspace and not the encrypted system partition, then I should expect to not get any performance hit. Would I be correct? I guess it might depend on the application, if that app is hard-wired to use the system partition always for temporary storage during editing and transcoding, or if it has to be installed on the C: system partition always. So some real data on how various apps behave in the respect would be useful, e.g. Adobe, Cyberlink, Nero etc. etc. I have a Intel i7 Quad-core (8 threads) 1.6Ghz (up to 2.8Ghz turbo-boost) 4Gb, 7200rpm SATA, nvidia HP laptop. I've read the excellent posting about the general performance impact of truecrypt but the benchmarks weren't specific enough for my needs where I'm dealing with HD-video and using a non-encrypted partition to maintain max performance.

  • Logitech QuickCam Pro 9000 & Windows 7 64-bit failing miserably

    - by Saxtus
    I am trying to install a Logitech QuickCam Pro 9000 webcam to Windows 7 64-bit. If I do it without using the Logitech drivers but instead the Windows Update ones, the camera works with low frame rate and without face tracking and all other bells and whistles that it's full driver provides. The moment I install the latest official Logitech driver, the problems begin: Camera works fine, until I decide to go to audio settings of the LWS panel or Windows'. Then LWS freezes and with it everything that tries to output audio. I am not able to open Playback/Recording devices window (it just doesn't appear) and system gets unstable and slow with LWS.EXE process not been able to close forcefully. If I reboot and forget the camera connected, this situation continues and system gets unstable from the beginning. If I reboot without the camera connected, everything works fine until I connect it and try to do something with audio settings of Windows or LWS panel. I should note, that until the freezing occurs, camera works as expected, with full frame rate, face tracking and everything that is expected to do. The soundcard is the ASUS SupremeFX II of the ASUS Striker II Extreme motherboard. Any ideas of what is causing this or what else to try so I can make it work as advertised? Thank you.

  • How to test nginx proxy timeouts

    - by mkorszun
    Target: I would like to test all Nginx proxy timeout parameters in very simple scenario. My first approach was to create really simple HTTP server and put some timeouts: Between listen and accept to test proxy_connect_timeout Between accept and read to test proxy_send_timeout Between read and send to test proxy_read_timeout Test: 1) Server code (python): import socket import os import time import threading def http_resp(conn): conn.send("HTTP/1.1 200 OK\r\n") conn.send("Content-Length: 0\r\n") conn.send("Content-Type: text/xml\r\n\r\n\r\n") def do(conn, addr): print 'Connected by', addr print 'Sleeping before reading data...' time.sleep(0) # Set to test proxy_send_timeout data = conn.recv(1024) print 'Sleeping before sending data...' time.sleep(0) # Set to test proxy_read_timeout http_resp(conn) print 'End of data stream, closing connection' conn.close() def main(): s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) s.bind(('', int(os.environ['PORT']))) s.listen(1) print 'Sleeping before accept...' time.sleep(130) # Set to test proxy_connect_timeout while 1: conn, addr = s.accept() t = threading.Thread(target=do, args=(conn, addr)) t.start() if __name__ == "__main__": main() 2) Nginx configuration: I have extended Nginx default configuration by setting explicitly proxy_connect_timeout and adding proxy_pass pointing to my local HTTP server: location / { proxy_pass http://localhost:8888; proxy_connect_timeout 200; } 3) Observation: proxy_connect_timeout - Even though setting it to 200s and sleeping only 130s between listen and accept Nginx returns 504 after ~60s which might be because of the default proxy_read_timeout value. I do not understand how proxy_read_timeout could affect connection at so early stage (before accept). I would expect 200 here. Please explain! proxy_send_timeout - I am not sure if my approach to test proxy_send_timeout is correct - i think i still do not understand this parameter correctly. After all, delay between accept and read does not force proxy_send_timeout. proxy_read_timeout - it seems to be pretty straightforward. Setting delay between read and write does the job. So I guess my assumptions are wrong and probably I do not understand proxy_connect and proxy_send timeouts properly. Can some explain them to me using above test if possible (or modifying if required).

  • Ubuntu 9.04: Ripping CDs with grip?

    - by chris
    I tried to rip a CD tonight, and couldn't figure out how to configure grip - /dev/cdrom doesn't seem to be the mount point for music CDs any more. How can I configure grip to find CDs? Update: /etc/fstab has /dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0 But there's nothing visible in /media/cdrom0 (or /media/cdrom, which is a symlink to cdrom0) There's an icon on the desktop labeled "Audio Disk" and opening it shows the .wav files on the CD. The location is cdda://sr0/, but grip doesn't like that either. Trying to manually mount /dev/sr0, I get $ sudo mount -t auto /dev/sr0 foo/ mount: block device /dev/sr0 is write-protected, mounting read-only mount: you must specify the filesystem type Update 2: Tried to change the media handling preferences (From a file browser, Edit-Preferences, Media, CD Audio) to "Do Nothing". CD Still doesn't mount. Update 3: With an audio CD in the drive: $ ls -l /dev/ | grep cd lrwxrwxrwx 1 root root 3 2009-09-15 22:13 cdrom1 -> sr0 lrwxrwxrwx 1 root root 3 2009-09-15 22:13 cdrw1 -> sr0 drwxr-xr-x 2 root root 60 2009-09-15 22:13 pktcdvd lrwxrwxrwx 1 root root 3 2009-09-15 22:13 scd0 -> sr0 crw-rw----+ 1 root cdrom 21, 2 2009-09-15 22:13 sg2 brw-rw----+ 1 root cdrom 11, 0 2009-09-15 22:13 sr0

  • Hearing a clicking noise from soundcard all the time

    - by Mehrdad
    I have installed Fedora 17 on my laptop. A few days ago I updated my fedora (but not upgraded). I shut down my computer and since the next time I turned it on I am hearing a clicking noise all the time from speakers. Even when I plug my headphones in I hear the noise through the headphone. I surfed over the internet and found the following shell commands: su -c 'echo "options snd_hda_intel power_save=0" /etc/modprobe.d/snd_hda_intel.conf' su -c 'echo 0 /sys/module/snd_hda_intel/parameters/power_save' I tried them but they didn't work. Here is the part of "lspci" command related to my sound-card: 00:1b.0 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 03) I have to add that my sound-card is working and I can play some audio file, I mean I can hear the voice and noise simultaneously. But everything is OK in windows xp which is also installed on my laptop. Could it be related to the sound-card driver? If so, how can I revert it to the previous version?
