  • Why does 3.5 mm audio out work through headphones but not through external speakers?

    - by Rickster
    I have a computer that has a 3.5 mm audio jack on the front of it. The computer itself has no speakers, so this is the only way to hear sound. If I plug headphones into it, the audio properly plays through the headphones, and if I plug in external speakers it used to play through them as well. Just today I turned on my computer and the audio no longer plays through the speakers, but if I plug in the headphones instead it works. The speakers aren't broken, as both the speakers and headphones work in my iPod and play music. I thought that 3.5 mm jacks could not send data back to the computer, and the computer had no way of differentiating between different devices plugged into the jack. If this is true, how is it that the computer plays audio through the headphones but not through speakers plugged into the same 3.5 mm jack, and both devices are functional? Or is my knowledge on 3.5 mm jacks incorrect? I don't believe drivers are important, as the same driver runs the 3.5 mm jack for all devices, but if necessary I can provide additional information. Any ideas would be appreciated. Thanks!

  • Using photos from network drive with Windows 8 photo app

    - by Paul
    I have photos on my network drive that I want to display (in live tiles preferably in the photo app). Under c:\users\paul\pictures I have made a link to them, using mklink /d: And this works fine in classic: But nothing appears in the photo.app: I am guessing that this is an issue with indexing - the photos won't appear until they are indexed, and Windows won't normally index a network drive (unless you make it "available offline, which just copies the files locally) - but this is exactly what the mklink was supposed to work around, and the properties show it is indexable: Any ideas?

  • Automount of AFP shares on Lion clients from OS X Snow Leopard server - not working right

    - by Paul
    Recently upgraded Snow Leopard clients to Lion. AFP shares are set up as login items. The network shares on some of the machines now take a long time to come up (10 minutes). Several machines that were upgraded are acting normally, and three machines with clean installs of Lion (not upgraded) are also working normally. Is there a network file causing a conflict on some of these client machines? Thanks, Paul

    Is there a way to AUTOMATICALLY open all links in a given website in different tabs or windows? I've tried "snap link plus", but it didn't work on this particular website: http://www.teledunet.com To open others streams on this website (found on the left hand side of the page), you would need to login using (cmoi123 / 12345) by clicking on "Connexion" on the top right side of the main page).

  • Network Transfer Rate on SMB/FTP

    - by Jack Sleight
    Hi, We're trying to optimise our network transfer rate from the client PCs to the file server, but having no luck. If I run an iperf test between a client PC (Windows XP) and our server (Linux) with a large TCP window size (the default is 8kb) I can get 60 Mbps. But when I run an SMB transfer speed test all I get is around 35 Mbps. When I run an FTP transfer speed test all I get is around 32 Mbps. I thought this was to do with the TCP window size, but I have now increased that to 256960 and it made no difference at all. Any ideas what I'm doing wrong? Or is 35 Mbps all I should expect? Cheers, Jack

  • SkyDrive and Consumer Cloud Services

    - by Tim Murphy
    Paul Thurrrott recently posted an article on the future of SkyDrive and I was asked what I thought about its future by @UserCommunity.  So let’s take a look. The breakdown from Microsoft that Paul described I believe is an accurate representation of users and usages. While I can’t say that I leverage SkyDrive to the extent that it was meant to be I do enjoy having OneNote hosted their and being able to consult and edit it from the desktop, web and Windows Phone. Taking that one step further is the Midwest Geeks group which started as the community of Microsoft related user groups in our region uses SkyDrive groups and shares calendars and documents.  This collaboration aspect isn’t new in itself, but having it connected with the rest of your cloud assets makes life easier. Another recent usage of this type of cloud service is storing your personal music files in order to get that same universal access.  This is a scenario that has some arguments for and against.  On the one hand own once and listen anywhere is great, but the on the other hand the bandwidth cost becomes a giant downside.  This is especially the case since most carriers are now doing away with unlimited data packages. Ultimately I see this type of resource growing an evolving at a phenomenal rate over the next few years as we continue to become more mobile.  Having multiple players such as SkyDrive and iCloud will only help to give us more options.  Only time will tell where we end up next. del.icio.us Tags: SkyDrive,Cloud Services,Paul Thurrott,UserCommunity

  • Samba users are writing files with the same owner

    - by Alex
    I created a Samba share and 3 users (Marc, Mary and Paul), both in Ubuntu (12.04 LTS) and Samba. Then I configured 3 Win7 computers to access the share, each with different credentials. I created 3 folders, one for every user, and chown'd them to the related user, chmod'd them to 0700 and even restarted Samba. Every time that Mary or Paul create a file or a directory in the share, it ends up to be owned by Marc. They all can access the Marc folder, but none can open Mary's or Paul's. Can you help me with this problem? What am I missing?

  • Alternatives to FTP

    - by Jack Hickerson
    I need to share files with clients outside of my business and unfortunately our FTP server is becoming too much of a hassle (with regards to clients use of an ftp client and creating password protected downloads based on customized account privileges) Essentially, I need: a remote service that mimics an FTP server with a web interface (easy for basic internet users to comprehend). over 100gb of storage file transfer size over 2gb customizable user account privileges (password protected downloads) secure storage and data transfer preferably less then $100/mo I have already looked into some services that almost meet my requirements (StreamFile.com, box.net, onehub.com, filesanywhere.com)- has anyone used a service they would recommend? cheers, jack

  • Question about Domain Forwarding [beginner]

    - by Jack W-H
    Hello folks Just a quick beginner's question here. I have a webapp located at domainxyz.com, and it generates short URLs for long posts automatically - so rather than visit domainxyz.com/reallylongpostnamehere I can just type domainxyz.com/a5c and be taken there automatically. However, I've bought a shorter domain name - short.com - and I want to be able to visit short.com/a5c and be redirected (or forwarded) to domainxyz.com/a5c. Or short.com/7f0 -- domainxyz.com/7f0. This way, although it seems a tad illogical it saves me setting up another hosting account on short.com to deal with the URL shortening. Is this possible? I realise you can forward domains, but, can you forward domains AND forward the URL segments? Thanks! Jack

  • Restore audio settings - cannot open mixer: No such file or directory

    - by Alfred M.
    The internal speaker of my laptop never functionned under Ubuntu. I tried to follow indication on the web and now the jack audio does not work either. The graphic interface for audio management now displays a 'dummy output' instead of the three possible outputs I used to have (one of them was working for the jack output). In a terminal alsamixer raises an error: cannot open mixer: No such file or directory I did try to remove and reinstall alsa-utils but it did not change anything. This happened after a failed atempt to install alsa-driver-linuxant_1.0.23.1_all.deb from here. My sound card seems to be not recognised anymore. After reboot I have no more the sound icon in menu bar the upper right corner. I think I have removed my sound card driver. Indeed, the command sudo lshw -class multimedia indicated audi device as unclaimed. Any idea how I could revert to a better situation (that is jack support and alsa working)? EDIT: The command lspci -nnk | grep -iEA3 audio gives lspci -nnk | grep -iEA3 audio 00:1b.0 Audio device [0403]: Intel Corporation 82801I (ICH9 Family) HD Audio Controller [8086:293e] (rev 03) Subsystem: ASUSTeK Computer Inc.

  • Why do we need Hash by key? [migrated]

    - by Royi Namir
    (i'm just trying to find what am I missing...) Assuming John have a clear text message , he can create a regular hash ( like md5 , or sha256) and then encrypt the message. John can now send Paul the message + its (clear text)hash and Paul can know if the message was altered. ( decrypt and then compare hashes). Even if an attacker can change the encrpyted data ( without decrypt) - - when paul will open the message - and recalc the hash - it wont generate the same hash as the one john sent him. so why do we need hash by key ?

  • Web and email host migration - Limitations and suggestions to make the process as easy as possible.

    - by Jack Hickerson
    I developed a website for a friend of mine to replace his current 'all inclusive' provider (website creation, updating, web hosting, email hosting). I've already paid for a hosting service which currently houses the website which I have created. I need to cancel the previous service provider to get the domain migrated to the new host, however I will still need to transfer or recreate all of the email addresses that everyone in his company had previously. Is there an easy way migrate email accounts (still linked to the same domain) while migrating to a different host? Will any methods allow all users to retain their archived emails and folder structures? What is the process to do so. Because the current provider is a rather large website development and hosting company, I will have limited access to the data they have stored. As you can probably tell, my knowledge in this area is very limited - any/all suggestions you may have would be greatly appreciated. Thanks in advance. -Jack

  • Security in Robots and Automated Systems

    - by Roger Brinkley
    Alex Dropplinger posted a Freescale blog on Securing Robotics and Automated Systems where she asks the question,“How should we secure robotics and automated systems?”.My first thought on this was duh, make sure your robot is running Java. Java's built-in services for authentication, authorization, encryption/confidentiality, and the like can be leveraged and benefit robotic or autonomous implementations. Leveraging these built-in services and pluggable encryption models of Java makes adding security to an exist bot implementation much easier. But then I thought I should ask an expert on robotics so I fired the question off to Paul Perrone of Perrone Robotics. Paul's build automated vehicles and other forms of embedded devices like auto monitoring of commercial vehicles on highways.He says that most of the works that robots do now are autonomous so it isn't a problem in the short term. But long term projects like collision avoidance technology in automobiles are going to require it.Some of the work he's doing with his Java-based MAX, set of software building blocks containing a wide range of low level and higher level software modules that developers can use to build simple to complex robot and automation applications faster and cheaper, already provide some support for JAUS compliance and because their based on Java, access to standards based security APIs.But, as Paul explained to me, "the bottom line is…it depends on the criticality level of the bot, it's network connectivity, and whether or not a standards compliance is required."

  • TechEd 2012: MVVM In XAML

    - by Tim Murphy
    Paul Sheriff was a real character at the start of his MVVM in XAML session.  There was a lot of sarcasm and self deprecation going on prior to the .  That is never a bad way to get things rolling right after lunch.  Then things got semi-serious. The presentation itself had a number of surprises, but not all of them had to do with XAML.  When he flipped over his company’s code generation tool it took me off guard.  I am used to generator that create code for a whole project, but his tools were able to create different types of constructs on demand.  It also made it easier to follow what he was doing than some of the other demos I have seen this week where people were using code snippets. Getting to the heart of the topic I found myself thinking that I may have found my utopia for application development in MVVM.  Yes, I know there is no such thing, but this comes closer than any other pattern I have learned about.  This pattern allows the application to have better separation of concerns than I have seen before.  This is especially true since you can leverage data binding.  I’m not sure why it has taken me so long to find time for this subject. As Paul demonstrated using this pattern with XAML gives you multi-platform reusable code when you leverage common utility classes and ModelView classes.  The one drawback I see is that you have to go to the lowest common denominator between the platforms you want to support, but you always have to weigh the trade offs. And finally, the Visual Studio nuggets just keep coming.  Even though it has been available for several generations of Visual Studio I have never seen someone use linked files within a solution.  It just goes to show that I should spend more time exploring the deeper features of each dialog. del.icio.us Tags: TechEd,TechEd 2012,MVVM,Paul Sheriff,Patterns,Visual Studio 2012

  • How to rewrite using htaccess if the file exists in another folder?

    - by Jack
    We are trying to rewrite to another folder if the file does not exist in the document root, but does exist in the other folder. The other folder is in a completely different location, which is located using "Alias" in the vhosts. So, what we have so far (from this post How to rewrite URI from root if file exists in folder?) is: RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_URI} !^/legacy/ RewriteRule ^(.*)$ legacy/$1 [QSA,L] This works to an extent, but seems to direct everything to the legacy folder, not just when the file doesn't exist in the first location and does exist in legacy. Thanks in advance for any help, Jack.

  • Problems when loop over a series of ssh-ed commands

    - by Jack Medley
    I have a series of server machines which I want to run the same command on. Each command takes hours and (even though I am running the commands using nohup and setting them to run in the background) I have to wait for each to finish before the next starts. Here is roughly how I have set it up: On the host machines: for i in {1..9}; do ssh RemoteMachine${i} ./RunJobs.sh; done Where RunJobs.sh on each remote machine is: source ~/.bash_profile cd AriadneMatching for file in FileDirectory/Input_*; do nohup ./Executable ${file} & done exit Does anyone know of a way such that I dont have to wait for each job to finish before the next starts? Or alternatively a better way of doing this, I have a feeling what I am do is fairly sub-optimal. Cheers, Jack

  • Catch headset pause/play keypresses in Windows

    - by akshay2000
    I have a new Ultrabook which has single audio jack for input and output instead for separate 3.5 mm jacks we used to have on older machines. The jack is probably similar to American Audio Jack specification or like the one found on Macbook Pro. I have tried to use it with the Apple, HTC, Nokia earphones which ship with most of the smartphones. Microphone on the headset works the way it should. Thing is that the headsets also come with remote controls to control volume and playback. I am sure that those key presses are sent to the Windows. I was hoping to catch those events and bind those to actual media keys so that I can control music playback. I guess this happens on Macs. I want to do the similar thing on the Windows. I'm just not sure where I can catch the events. Driver level? Application level?
