    Edgar,

    Thank you for reporting that. James is correct that we updated the course for the new objectives, but it looks like we forgot to update the overview video to reflect the changes. I am out of the office right now, but Justin will re-record the overview video on Monday and we'll get it updated. Sorry for the confusion.

    Tim,

    Thanks for writing in. You are absolutely correct and I mispoke in the episode. su by itself would require you to enter the root user's password, but sudo requires the user's password (assuming they were in the /etc/sudoers file) as you described. I'll have to see if I can correct that in the episode, or re-film it as that is a pretty big mistake.

    Thanks again,

    Don

    Which virtualization platform are you using? If you are using Hyper-V you can just setup a shared network for the VM, the host and the physical adapter which would suite your needs. If you are using VirtualBox it is a little harder as you may need to setup a virtual bridge in your host OS to connect the VM to the physical adapter and still have the host involved.

    That being said, your network may already be setup properly. The fact that your Windows 10 host can ping everything makes me suspect you are setup correctly, but that the Windows firewall maybe blocking communications between your devices. I would suggest temporarily disabling the Windows firewall and seeing if everything communicates properly. If it does, turn the firewall back on and add rules allowing traffic between the three IPs you are using.

    Thanks for watching,

    Michael,

    Could I bother you for a little more information on this? I took a look at the series and I don't see anything missing as far as I can tell. Was there a reference to some content that isn't there? For example, did I say there would be a second part to an episode, but there isn't one?

    The progress bar indicates the amount of the content that you have watched. If you have watched all of the videos and it reflects 80% complete, then it is also possible that the problem is with our website reporting your video stats. Have you noticed any problems with the videos resuming where you left off? I asked our dev team and they told me there is currently an issue with Android clients reporting viewing time. Are you using our Android or Fire TV app?

    Thanks,

    Don Pezet

    I just heard from our producer and it looks like the site has been updated to reflect which section goes with which exam. Here's the new list:

    (LX0-103) Exploring Linux Command-Line Tools
    (LX0-103) Managing Software
    (LX0-103) Configuring Hardware
    (LX0-103) Managing Files
    (LX0-103) Booting Linux and Editing Files
    (LX0-104) Configuring the X Window System, Localization and Printing
    (LX0-104) Administering the System
    (LX0-104) Configuring Basic Networking
    (LX0-104) Writing Scripts, Configuring Email and Using Databases
    (LX0-104) Securing Your System

    OK, I see the problem. The right exam is linked, we just haven't identified which of our sections are tied to which exam. I have all that information in my notes. Let me get with our producer and I will have him update the site to reflect LX0-103 or LX0-104 for each section. Sorry for the confusion.

    Dana,

    I think this is a mistake on our end. I checked the Transcender website and the updated LX0-103 and LX0-104 exams are available so I am not sure why we are linking to the old exams. I'll reach out to our dev team and see what is going on.

    Thanks,

    Don

    Eric,

    Thank you for writing in. When you add your Mac to the domain, you will be able to login with domain accounts. Those accounts are separate from the local OS X user database, so they will get all new (empty) profiles.

    The official answer that there is no way to merge the profiles. You would then need to copy all of your data over from your old profile into the new one. Some preferences (like wallpaper) will not copy over, but your documents and other files will.

    However, Apple does have a round-about way that you can merge the two accounts. I usually use the method listed above because it is easy, but if you want to preserve things like 3rd party application prefences, you can follow the steps in this article to try and merge them.

    Hope that helps,

    Don Pezet

    @danny-perry Sorry for the super-late delay in answering this question. I could have sworn I already answered it, but Ronnie pointed it out to me this morning.

    Anyhow, the answer to your question is that Hyperthreading can create unreliable performance results. Sometimes you have the speed, and sometimes you don't. VMware's official stance is this:

    An ESX/ESXi host enabled for hyperthreading should behave similarly to a host without hyperthreading. You might need to consider certain factors if you enable hyperthreading, however.

    The example they give is:

    Consider your resource management needs before you enable CPU affinity on hosts using hyperthreading. For example, if you bind a high priority virtual machine to CPU 0 and another high priority virtual machine to CPU 1, the two virtual machines have to share the same physical core. In this case, it can be impossible to meet the resource demands of these virtual machines.

    You can read the full writeup in VMware's Resource Management Guide available here: Hyperthreading and ESX/ESXi Hosts.

    At the end of the day, Hyperthreading sometimes creates a performance benefit, but it always creates a performance risk as it might not be available when you need it. As a result, I recommend disabling it so that I always have reliable performance numbers. If you have 4 cores, but need 8 then you should upgrade to 8 cores instead of activating Hyperthreading.

    Hope that helps, and again, sorry for the insane delay in answering.

    @techgiant2000 I just did a test from my iPad running iOS 9.2 and I was able to AirPlay to my 3rd gen Apple TV using the Vimeo screen. The AirPlay icon was greyed out until I started playing the video and then I was able to select the Apple TV. Can you tell me what devices and software versions you are using?

    Thanks,
