    - by freebird
    For two days I have tried to get vlc play this .bin file. I played it fine in windows xp using vlc.

  • What determines which Javascript functions are blocking vs non-blocking?

    - by Sean
    I have been doing web-based Javascript (vanilla JS, jQuery, Backbone, etc.) for a few years now, and recently I've been doing some work with Node.js. It took me a while to get the hang of "non-blocking" programming, but I've now gotten used to using callbacks for IO operations and whatnot. I understand that Javascript is single-threaded by nature. I understand the concept of the Node "event queue". What I DON'T understand is what determines whether an individual javascript operation is "blocking" vs. "non-blocking". How do I know which operations I can depend on to produce an output synchronously for me to use in later code, and which ones I'll need to pass callbacks to so I can process the output after the initial operation has completed? Is there a list of Javascript functions somewhere that are asynchronous/non-blocking, and a list of ones that are synchronous/blocking? What is preventing my Javascript app from being one giant race condition? I know that operations that take a long time, like IO operations in Node and AJAX operations on the web, require them to be asynchronous and therefore use callbacks - but who is determining what qualifies as "a long time"? Is there some sort of trigger within these operations that removes them from the normal "event queue"? If not, what makes them different from simple operations like assigning values to variables or looping through arrays, which it seems we can depend on to finish in a synchronous manner? Perhaps I'm not even thinking of this correctly - hoping someone can set me straight. Thanks!

  • Naming a class that processes orders

    - by p.campbell
    I'm in the midst of refactoring a project. I've recently read Clean Code, and want to heed some of the advice within, with particular interest in Single Responsibility Principle (SRP). Currently, there's a class called OrderProcessor in the context of a manufacturing product order system. This class is currently performs the following routine every n minutes: check database for newly submitted + unprocessed orders (via a Data Layer class already, phew!) gather all the details of the orders mark them as in-process iterate through each to: perform some integrity checking call a web service on a 3rd party system to place the order check status return value of the web service for success/fail email somebody if web service returns fail constantly log to a text file on each operation or possible fail point I've started by breaking out this class into new classes like: OrderService - poor name. This is the one that wakes up every n minutes OrderGatherer - calls the DL to get the order from the database OrderIterator (? seems too forced or poorly named) - OrderPlacer - calls web service to place the order EmailSender Logger I'm struggling to find good names for each class, and implementing SRP in a reasonable way. How could this class be separated into new class with discrete responsibilities?

  • Slow LAN transfer from 3rd party computer

    - by Chris
    Hi Everyone, I've got an odd problem that I'm not really sure where to start the troubleshooting process. I have a 'server' with Windows Server 2008R2 (64-bit) installed and it has a couple of hard drives. If I Remote Desktop into the server and transfer files from one HD to the other, all it fine. If however, I use my workstation (Windows 7 64bit) and open up a shared resource on the server and transfer a file from one hard drive on the server to another HD on the server (not using Remote Desktop, just Windows explorer/Network places), the transfer crawls... It takes about 5mins to discover files/calculate the transfer and then starts transferring at speeds like 56KB/s - 200KB/s. Both machines have Marvel GigE network ports with a TrendNet 8-port green GigE switch. I've set Jumbo packets to 9K on both machines...

  • Upgrade went wrong, laptop essentially 'bricked'

    - by hexagonheat
    I have an old netbook I was trying to upgrade from 10.04 to 10.10. Ubuntu was in the process of upgrading when everything completely froze. I left it sit for an hour but it would not respond to anything. So I powered down the machine and it didn't have the necessary files to run Ubuntu. I went to the terminal and it told me to put in some command that I can not remember to 'rebuild' something. That takes me to now, when I turn on the laptop it comes up with a screen "GNU GRUB version 1.98+20100804-5ubuntu3.3" and has a bunch of options such as: 1. Ubuntu, with Linux 2.6.35-32-generic 2. Ubuntu, with Linux 2.6.35-32-generic (recover mode) etc. (there are like 15 of these with different numbers after 2.6.35 and the word 'generic'. It doesn't seem to matter what I pick, it will go to the "Ubuntu" loading screen with the colored dots but then every time it will freeze and I have to reboot to the same thing. I can't seem to get a terminal prompt anywhere either. Any ideas? I can't think of what to do :(

  • Do I really need Microsoft Updates?

    - by Tony Wong
    When I install a fresh copy of Windows XP Home (I bought it from the store.. not a copy), my PC rocks like lightening speed. But when I start installing all the updates, patches & less .NET 4.0 client (as the .NET 4.0 Client seems to bring machine to slow crawl). The PC starts to slow down.. like there are more resources to watch or something is happening in the background. So could I not get away with an awesome virus protector and an awesome firewall set-up and avoid all the patches? The machine I have is a quad 4, 4 GB RAM and 2.3 GHz process. Tons of room and the machine can run several applications at one time.. but when the updates happen.. it's s-l-o-w!

  • How can I make Windows Media Player ignore global hotkeys in Windows 7?

    - by Schnapple
    I have Windows 7 and a Logitech G15 keyboard. One of the programs with the Logitech G15 allows you to control media players such as Winamp with the playback keys on the keyboard. Problem I'm having is that, even though I have told this program to not control Windows Media Player, every time I use it to pause Winamp, it then hits plays (or unpauses) Windows Media Player. Even more annoying given that Windows Media Player isn't even running as an active GUI program and instead as a background process, so I hear the sound of whatever the last video it was I playing. If I end-task wmplayer.exe it spins right back up but at least now it has no knowledge of a video to play, but this is annoying. How can I either a) Have Windows Media Player in Windows 7 completely unload when I close it, or b) Have Windows Media Player in Windows 7 ignore any sort of global hotkeys?

  • Frustrated with MythTV 0.26

    - by Mike
    I've been using MythTV for a while now. Until a hardware crash I had a 0.25 box running without problems. Had to get new hardware and am now in the process of setting up 0.26. Every time I pick a menu option, it hangs for 1 minute. Every time I try to start the backend, same thing. I pick a new theme in the frontend, but it never gets used. I try to test audio, but all I get is static (from the proper channels though). I've setup the storage groups in the backend and put a video in /storage/videos but the front end won't see it when I scan for changes. I make changes in the front end configuration and they don't get saved (or get lost randomly 2-3 reloads later). Obviously there is something I am doing catastrophically wrong, but I have no idea what. Are the storage groups not working yet? Maybe I need to delete all the storage group entries and just use the front end override to set the path? I'm currently using lvm across 3 hard disks, and this has worked well for me in the past. I'd like to use storage groups, but frankly I don't see them working yet at all - especially not for videos (which is what we watch 99% of the time). Anyone have any suggestions for me to try before I just call 0.26 bad names and wipe the system?

  • Can a MySQL slave be a master at the same time?

    - by mmattax
    I am in the process of migrating 2 DB servers (Master & Slave) to two new DB Servers (Master and Slave) DB1 - Master (production) DB2 - Slave (production) DB3 - New Master DB4 - New Slave Currently I have the replication set up as: DB1 -> DB2 DB3 -> DB4 To get the production data replicated to the new servers, I'd like to get it "daisy chained" so that it looks like this: DB1 -> DB2 -> DB3 -> DB4 Is this possible? When I run show master status; on DB2 (the production slave) the binlog possition never seems to change: +------------------+----------+--------------+------------------+ | File | Position | Binlog_Do_DB | Binlog_Ignore_DB | +------------------+----------+--------------+------------------+ | mysql-bin.000020 | 98 | | | +------------------+----------+--------------+------------------+ I'm a bit confused as to why the binlog position is not changing on DB2, Ideally it will be the master to DB3.

  • Kaspersky processing error Explorer.exe (recycle bin)

    - by aeternus828
    I get daily critical errors from Kaspersky involving Explorer.exe... The file in question is almost always in the Recycle Bin, or something on the desktop. Here is an example error detail: Event type: Processing error Application\Name: EXPLORER.EXE Application\Path: C:\WINDOWS\ Application\Process ID: 2364 Application\Options: C:\windows\Explorer.EXE Component: File Anti-Virus Result\Description: Processing error Object: C:\$Recycle.Bin\S-1-5-21-1403139956-787289773-2644151291-500\$RIKKQKS Object\Type: File Object\Path: C:\$Recycle.Bin\S-1-5-21-1403139956-787289773-2644151291-500\ Object\Name: $RIKKQKS Reason: Read error Google searches didn't offer much insight, so I thought I'd ask here if anyone has encountered a similar situation. Not sure if it's a bug, something to be concerned about, or an easy fix, etc. I usually just empty the recycle bin for a temporary fix, but would like to get to the root of the error. Thoughts?

  • what does it mean for MalwareBytes to find malicious registry keys but nothing else?

    - by EndangeringSpecies
    I have a machine that is obviously infected, and when I ran MalwareBytes it told me that it found some "malicious" registry keys (surprisingly enough these contained file path to currently non-existent javascript files). But, that's it. Full scan did not uncover any malicious files, or malicious hidden processes in memory. Like, maybe the (hidden?) process that for whatever reason periodically injects keystrokes (hotkeys?) into whatever currently open window. Then on another, not obviously infected, machine it found a "malware.trace" registry key but again no files or processes etc. How does this jive with people's experience with MalwareBytes? Does it usually find registry key symptoms of an infection but nothing else? Or is it a common thing to have no infection but some malicious registry keys in place anyway?

  • Slow Web Performance on two Windows 2008 R2 Terminal Servers

    - by Frank Owen
    We have two Windows 2008 R2 servers that we use for agents to log into to access our customers systems. Saturday morning we received complaints that on both servers the web is running horribly slow. This happens on all websites and the majority of the time the web site times out trying to load. Other users located at the same site but using their desktop machine do not see any issue. We have rebooted the boxes and checked settings and cannot find the cause. The CPU/Memory/Network/Disk Space use on the server is very low. I thought it might have been a MS update causing the issue but it appears the last update was applied in January. We have rebooted both boxes and I am in process of trying a different browser. Any ideas what could be causing this?

  • Allow READ access to local folders in 2003SBS AD

    - by Dan M.
    Have a SBS2003 client with a mess of a domain that is in process of being cleaned. But, for the life of me I cannot find a setting that will allow write access to the local hard disk for domain users with redirected profiles(to the server). This is needed only for one program that will not follow a symbolic link to the network path, instead it seems to be hard coded to the %appdata% folder but only on the c: drive.... So question is how can I allow "Domain users" write access to the local %appdata% directory? I have tried setting it manually on a machine but it kept resetting to RO no matter how many times I tried. Everytime I would uncheck the RO property it would reset sometime right after i hit OK. Thanks in advance! Dan

  • How do I modify these VPN connection settings for Xfce?

    - by Dave M G
    I have signed up for a VPN (Virtual Private Network) service, and I configured it for use on my computer that runs Gnome Classic with the following instructions: In Terminal, install openvpn packages with sudo apt-get install network-manager-openvpn. 1. Restart the network manager with sudo restart network-manager 2. Run sudo wget https://www.xxxxxxx.com/ovpnconfigure.zip 3. Extract the files from the zip with unzip ovpnconfigure.zip. 4. Move cert.crt to /etc/openvpn 5. Open the Network Manager on the menu bar. 6. Choose add and select the OpenVPN connection type, and click Create. 7. Enter Private Internet Access SSL for the Connection Name. 8. Enter xxxxxx.xxxxxxxx.com for the Gateway 9. Select Password and enter your login credentials. 10. Browse and select the CA Certificate we saved in Step 3. 11. Choose Advanced and enable LZO Compression. 12. Apply and exit. 13. Connect using the Network Manager. It worked, but now I want to set up access to the same VPN service on another machine that runs Mythbuntu, which uses Xfce as its desktop manager. So every point from 5 on doesn't apply. How can I modify the above instructions so that I can get my VPN service working with Xfce. As a further note, while I can access the Xfce desktop directly if I need to, it's more convenient for me to access it via the command line and SSH from on of my other computers. A command line process would be ideal. (I looked for this, and found instructions only for PPTP access, whereas I need OpenVPN.)

  • What would happen if I did a "Boot to VHD" to a VHD that was configured to run under Hyper-V?

    - by tbone
    Microsoft has a Hyper-V based VM I'm interested in running, however, I don't have access to a Windows Server 2008 machine to try it on, only a Windows 7 Pro x64 machine (Windows 7 does not support Hyper-V). This is the VM in question: This download contains three Windows Server 2008 R2 SP1 Hyper-V Virtual Machine set for evaluating and demonstrating Office 2010, SharePoint 2010 and Project Server 2010. 2010 Information Worker Demonstration and Evaluation Virtual Machine (SP1) http://www.microsoft.com/en-us/download/details.aspx?displaylang=en&id=27417 I came across a somewhat relevant article from Scott Hanselman: Less Virtual, More Machine - Windows 7 and the magic of Boot to VHD: http://www.hanselman.com/blog/LessVirtualMoreMachineWindows7AndTheMagicOfBootToVHD.aspx I realize other options are to convert this VM to a VMWare compatible VM or some of the options to run it under VirtualBox. But instead of those routes, I'm wondering: What would happen if I tried to go the "Boot to VHD" route using this Hyper-V VHD? Is it possible that during the boot process, Windows would simply notice that hardware had changed and adjust accordingly, installing the appropriate drivers and continuing on without a hitch?

  • Is version history really sacred or is it better to rebase?

    - by dukeofgaming
    I've always agreed with Mercurial's mantra, however, now that Mercurial comes bundled with the rebase extension and it is a popular practice in git, I'm wondering if it could really be regarded as a "bad practice", or at least bad enough to avoid using. In any case, I'm aware of rebasing being dangerous after pushing. OTOH, I see the point of trying to package 5 commits in a single one to make it look niftier (specially at in a production branch), however, personally I think would be better to be able to see partial commits to a feature where some experimentation is done, even if it is not as nifty, but seeing something like "Tried to do it way X but it is not as optimal as Y after all, doing it Z taking Y as base" would IMHO have good value to those studying the codebase and follow the developers train of thought. My very opinionated (as in dumb, visceral, biased) point of view is that programmers like rebase to hide mistakes... and I don't think this is good for the project at all. So my question is: have you really found valuable to have such "organic commits" (i.e. untampered history) in practice?, or conversely, do you prefer to run into nifty well-packed commits and disregard the programmers' experimentation process?; whichever one you chose, why does that work for you? (having other team members to keep history, or alternatively, rebasing it).

  • Keyboard causing freezes

    - by fluteflute
    My problem started on Windows XP: a computer (that was working fine for many years) had a problem, that I can't quite remember (may have been to do with the startup process) - but I solved it by swapping the keyboard with one on another machine. Now for several years the problematic keyboard has been working fine - on my main machine that runs Ubuntu. I also dual boot Windows XP - and have had no problems on either OS. However I recently installed Ubuntu 11.04 Natty (pre-alpha) and found that any keyboard press causes freezes. (All still works fine on Ubuntu 10.10 and 10.04 and Windows XP) Just wondering why I might be experiencing this? Seems strange to me that's its not consistent.

  • Block-level deduplicating filesystem

    - by James Haigh
    I'm looking for a deduplicating copy-on-write filesystem solution for general user data such as /home and backups of it. It should use online/inline/synchronous deduplication at the block-level using secure hashing (for negligible chance of collisions) such as SHA256 or TTH. Duplicate blocks need not even touch the disk. The idea is that I should be able to just copy /home/<user> to an external HDD with the same such filesystem to do a backup. Simple. No messing around with incremental backups where corruption to any of the snapshots will nearly always break all later snapshots, and no need to use a specific tool to delete or 'checkout' a snapshot. Everything should simply be done from the file browser without worry. Can you imagine how easy this would be? I'd never have to think twice about backing-up again! I don't mind a performance hit, reliability is the main concern. Although, with specific implementations of cp, mv and scp, and a file browser plugin, these operations would be very fast, especially when there is a lot of duplication as they would only need to transfer the absent blocks. Accidentally using conventional copy tools that do not integrate with the FS would merely take longer, waste some bandwidth when copying remotely and waste some CPU, as the duplicate data would be re-read, re-transferred and re-hashed (although nothing would be re-written), but would absolutely not corrupt anything. (Some filesharing software may also be able to benefit by integrating with the FS.) So what's the best way of doing this? I've looked at some options: lessfs - Looks unmaintained. Any good? [Opendedup/SDFS][3] - Java? Could I use this on Android?! What does [SDFS][4] stand for? [Btrfs][5] - Some patches floating around on mailing list archives, but no real support. [ZFS][6] - Hopefully they'll one day relicense under a true Free/Opensource GPL-compatible licence. Also, 2 years ago I had a go at an attempt in Python using Fuse at the file-level to be used over the top of a typical solid FS such as EXT4, but I found Fuse for Python underdocumented and didn't manage to implement all of the system calls. My first post here, so I can't post more than 2 links until I get over 10 rep: [3]: http://www.opendedup.org/ [4]: https://en.wikipedia.org/w/index.php?title=SDFS&action=edit&redlink=1 [5]: https://en.wikipedia.org/wiki/Btrfs#Features [6]: https://en.wikipedia.org/wiki/ZFS#Linux

  • RAID 1 after install and two controlers

    - by jfreak53
    I have question regarding RAID 1. Can I setup software RAID 1 after having installed the first drive and setup ubuntu 12? I know that during server install and partitioning I can select RAID and setup then, but what I am not clear on is how in the world to setup RAID 1 after the fact? Can someone provide directions for this? Also, can I RAID 1 two drives one being 500GB and the mirror drive being 1TB? Of course the mirror drive would have a 500GB partition but that's my point. Lastly, can one drive be on IDE and the other on a SATA controller? I know speed will be an issue, that doesn't matter, I just need to know if it will work without corrupting data and if it's the same process? Thanks.
