Question about wiki instruction

I'm planning on installing Arch to a USB.  I'm following this guide.  I'm going to use method #2. 
Regarding ''CHROOT_DIR=archinstall-chroot Must Change First, or you might ruin your /etc/", I am not so sure what to change CHROOT_DIR to.  Could anyone help me out?  Thanks!

I assume that when you say that it came with four primary partitions, you are sure that it is booting via bios mode and is formatted with MBR partitioning?  Because if it is GPT, then windows is booting via UEFI, and GPT can hold up to 128 primary partitions by default (this can be changed at the time you create the partition table).
That is indeed the guide I was referring to.  Though if you are going to use UEFI, creating a UEFI bootable installer is a bit different than a simple dd.  Whatever you do, don't use unetbootin, as it is not worth the trouble.
If you want to learn about Linux, and are aftraid to go about removing partitions, I would recommend using virtualbox instead.  It is very free, and it works quite well, and is fairly user friendly.  There are other virtualization options out there, but virtualbox tends to be the choice of Linux users since it is open source (or at least there is an open source version).  This way you can also still have a running system to view the wiki off of as well, while you learn how to set up your system.  With a bare metal installation of any kind, you are going to have to start with terminal/tty, in which you can access the wiki and whatnot with things like elinks or w3m, but it will be text only.
I have never tried to make a system that gets loaded into RAM, so I am not sure about how to do this.  It sounds like you are new(ish) to linux.  I am not trying to discourage you, so don't take this that way, but maybe it might be better to start off with a simple normal installation before moving on to things like making a system that gets loaded into RAM.  That is learn about how the stuff works before moving to more advanced topics.  Also, if you are really really new to Linux, it might serve you better to start with a more user friendly distribution, where you can kind of get your feet wet before diving in to something like Arch Linux.  Arch Linux isn't all that hard, but it takes a strong desire to learn if you are totally new (or sometimes even a seasoned Linux user). 
Oh and regarding the four primary partitions, wth MBR partitioning, you do indeed get four primary partitions, but you can also have as many extended partitions as you want.  So if the recovery and hp tools partitions are important to you, you would want to figure out how to back those up, and then zap them from the HDD.  Then adjust the C: partition to allow the size of you desired Linux, and go from there.  Just don't remove the C: or the system partitions and you will keep a bootable windows inatllation.

  • Had to change my Apple ID because the original email address is no longer valid.  How do I change the iCloud user name on iMac?  I found instructions about signing out of iCloud and signing back end.  It asks questions about contact, etc.

    Had to change Apple ID due to email address no longer valid.  Trying to change id for icloud...saw direction online about signing out of icloud and signing back in...when it ask questions about contacts, photos, etc. being deleted how do I answer those?  That just sort of freaks me out.

    For the ones that give you an option, select the option you want (keep on the Mac or Delete). For the ones that are simply warning you, click on Delete from Mac.
    They will all come back when you sign back on, since all you did was change your existing Apple ID to a new email address. It's the same iCloud account, just with a different name.
    It's the only way to get your updated ID signed onto iCloud.

  • [SOLVED] Question about resolv.conf

    I successfully configured my Arch box with a static IP by following the instructions on the Arch wiki page here but had a couple of questions about configuring /etc/resolv.conf:
    1) What is the proper way to obtain the domain name that should be inserted into resolv.conf?
    2) What exactly is this domain name used for?  I read the man page but still don't really understand it.  Why do I need a domain name if I already have a working set of nameservers to resolve IP addresses?
    EDIT: @ewaller Yes I edited the OP because I realized that my original problem was that I just hadn't added a domain name in my resolv.conf file.  I edited my original post because 1) the instructions are already posted clearly on Arch Wiki so my post really wouldn't be beneficial and 2) so I could ask my real question without making other people waste their time reading through my other nonsense

    Yes, I know how to get a nameserver, but I'm asking about the domain name that goes in resolv.conf.  The Arch wiki tutorial for setting up static IP uses the following resolv.conf as an example:
    nameserver 61.23.173.5
    nameserver 61.95.849.8
    search example.com
    My question has to do with what the "search example.com" does.  I don't have a domain name associated with my machine, but if I remove that line, then I get "web page unavailable" when I try to load any web site, which suggests that I'm not connecting to any nameservers right?

  • A lot of questions about my MacBook Air

    I am really new to re-using Apple computers.The last time I used an Apple computer was back in 1987 when the school and my family had Apple IIGS computers. I have been using PC's which reqiure Microsoft. I a lot of have questions (10 questions) about my MacBook Air and I hope you good people can and will help me.
    Product: MacBook Air
    Operating System: Mac OS X Version 10.7.4
    1) I Downloaded MacKeeper because I was fooled. I had a bad feeling just before I Downloaded it and I should have listened to my heart. However, I didn't buy it or fully Install it. It was like a test run and then they wanted me to pay almost $100 for it. Thankfully, I didn't because I read it is Malware. I spoke with an Apple Tech at Apple Care and he helped me get rid of it (or so we think). I don't see it anymore on my computer. I read it can slow down your computer. How can you tell if it's really off of the computer?
    2) When I open "Finder" and I see that there are people Sharing my computer with me. I went into AirDrop and it reads, "Other people can see your Mac as (my name) MacBook Air when their computer is nearby." I bought a HotSpot and while it's turned on and I selected it as my WI-FI connection I thought it would  get rid of these people, protect what I type, me, my items, computer, etc. But it didn't.  
    I didn't know that I have to buy a exteral CD and/or DVD Player in order to connect to the brand new Modem and Router in one by NetGear. I am so used to PCs and the CD/DVD Players being built inside.
    The people at Apple Store told me that there is an internal modem inside, but I don't know how to find it and what to do then.  Should I use a Firewall?, An AntiVirus, AntiMalware, AntiSpyware, etc. Apple Care tech told me I don't need to get an AntiVirus.
    3) Is there a new kind of Wireless Modem and Router that doesn't require a CD-ROM?
    4) When I travel or fly and I am not close to home I was told by Best Buy and Sprint that I had to buy a mobile HotSpot to use the computer (WI-FI) safely. As I typed, I have one. But it's pretty expensive and only gives me 1 hour and 15 minutes per day to Stream. What can I do to use this computer safely Online when I am out of range from a Modem and Router? What do people do when they travel on airplanes?  
    5) This compter won't let me use "Raid." I think you have to have a newer version. I hard about Raid on the radio from Leo (can't recall his last name) who's a Tech expert.
    6) Should I buy a ZipDrive? Apple Store Tech told me that I didn't need a ZipDrive. I just remember the episode of HBO's "Sex and The City" when Carrie looses everything because her copy crashed. Now, of course, I know that's a fictional show, but with PC's and Microsoft I have lost everything when it crashed, frooze up, etc. I know there's iClouds. I heard about Carbonite, but I have read the Pros and Cons about it. Mostly they are Cons about it. I just don't want to do anything wrong and mess up this computer.
    7) Should I buy a new Printer/Copier/Scanner because mine is an HP. It's not new, but it works. I even have a CD-ROM for Macs. What about the new product called, "Neat"?
    8) Is there a special product that I should buy to do Online Banking and/or other important stuff?
    9) I saw and read about iWork in the Apps Store and it sounds cool. I still have alot of friends and colleagues who still use Microsoft. Is iWork good to use? Should I Download it from the Apple Apps Store or can a buy it at Apple? Is there another Word Processing Program that is great and user friendly and will work with Macs and PCs?
    10) Should I Update the OS with OS X Mountian Lion Pro from the Apple Apps Store or buy it at Apple Store?
    In advance, I wish to thank you in this Apple Support Communites for your help.  Have a safe and happy holiday weekend!

    1) Here are instructions for removing MacKeeper. Since it mostly consists of manually looking for folders and specific files, if you follow the instructions you either fail to find what you are told to find (because your AppleCare guide gave you complete instructions which you followed) or you'll find some additional files that need to be replaced.
    2 & 3) I assume you are looking at the sidebar of a Finder window and seeing Shared and computers under it. Those are computers that you can potentionally share. To do so you'd need an account on their computer and a password. They are not sharing your computer.
    AirDrop allows you to create an adhoc network for filesharing and it only functions when you have selected the AirDop item in the SideBar. Actually doing that merely announces to computers in the same network node that your computer is available for a file to be sent to. Even then you have to explicitly allow the file to be downloaded to your computer. Similarly you'd be able to see other computers with AirDrop selected and be able to send them a file - which they'd have to accept.
    The only reason your NetGear Router comes with a CD is to install and run their 'easy' step by step configuration program. It can also be done manually with a browser. Read the manual to find the IP address you must enter to access the router's configuration menu. Apple's WiFi routers don't require a CD to install the software because the configuration software is already on your computer.
    I do have my firewall turned on. AntiVirus software isn't a bad idea - I use Sophos having tested it for a review for our local User Group and I found I liked it better than ClamAVx which is what I'd been using before. Both are free.
    4) I think you were scammed by Sprint and BestBuy. I use hotel, coffee shop, and restaurant WiFi spots and have for years. However, because they can be unsecured, I do not shop online or bank when I'm using them. I also use 1Password and don't reuse passwords so even if a sniffer should grab an account and password that's all it would get - one account.
    5) Raid doesn't really make sense with a MacBook Air - a RAID involves 2 or more disks being used as if they were one.
    6) Zip drive? No. External hard drive - yes. It isn't a question of if a computer's hard drive will malfunction, it is when. OWC has a nice selection of external drives and the Mac has a built in backup system called TimeMachine. Due to the way TimeMachine works, I've found that your TimeMachine drive should be at least twice as large - and preferably 3-4 times as large as the data you are backing up.
    7) if your printer works and it has Mountain Lion drivers, why replace it?
    8) Online banking is done with a browser - Use Safari or FireFox
    9) If trading files with Windows users is important Mac: Office is your best bet. If not, iWork, Mac:Office, or LibreOffice are all good possibilities.
    10) you can only buy Mt Lion via the App Store.

  • Question about swapping SIM cards on a Z10

    Hi, everyone, I am a non-Blackberry user who works in IT support.  One of my clients uses a Blackberry and has often asked me very complicated questions about how to do various unusual things with his device.  At the present time, he is considering switching to a Z10, which would be set up using ActiveSync.  He wants to know if he could swap the SIM card without having to go through the setup process again.   My client travels a lot, and wants to use a local SIM card on an upcoming trip to a very remote area.  
    I've not been able to find an answer to this anywhere. 
    This is his exact question: "I just got it from a friend (ATT version) and I am trying to see if I like it enough to switch to it as my primary phone.  Blackberry z10 asks you to sign in with your blackberry world ID when you first set up the phone.  Question: Would you have to do it again if you put a different simm into it?  With iPhone, it makes no difference so long as the device is unlocked—you can then exchange simm cards as often as you want.  Would it be the same with an unlocked blackberry z10 (I know it's not possible with the bold 9900 as System 7 ties your ID to the simm card).  In short, in blackberry z10, could you exchange the US simm for another country's simm without having to wipe the phone,  etc.  "
    If anyone can shed some light on this for me, I'd be very grateful.,  Thanks!

    Hi and Welcome to the Community!
    The key issues are thus:
    Ensuring that the device is truly carrier unlocked
    Ensuring that the specific device model is compatible with the radio frequencies/technologies that the desired carrier uses. There are 4 different Z10 models:
    http://www.bbin.in/en/2013/03/03/4-types-blackberry-z10-models-fits-better/?utm_campaign=4-types-of-...
    If both of those are OK (separate research of the desired carriers would of course be necessary), then it is indeed a simple matter to change carriers. For example, I changed from ATT to TMO by simply changing the SIM...no need to WIPE or anything, and my same BBID came along just fine. You should, however, always obtain a properly-sized SIM card from the carrier -- there are plenty of reports of folks trying to use "cut" SIM cards and experiencing errors.
    With BB10, it's actually simpler than with legacy BBs. Legacy BBs used the BIS service, which required receipt onto the device (from the carrier data network) of Service Books so as to activate the various services that the user subscribed to. When changing carriers, it often could be that a latent Service Book from the prior carrier causes issues when shifting to a different carrier...and that's where WIPING and such came into play, so as to cleanse the device so that the new carrier could deliver all of the proper Service Books to the device. With BB10, there is no BIS, and there are no Service Books...so all of that complication is eliminated.
    But, as always, YMMV.
    Good luck!

  • Newbie question about loading servlets on tomcat

    I have what is probably a very basic question about loading simple servlets on to tomcat to test its installation. I have followed instructions from numerous tutorials to the letter but still I can't get it to work.
    I have installed tomcat on win2k in c:\tomcat. I set up the jdk, environment vars (JAVA_HOME, CATALINA_HOME, TOMCAT_HOME) which all point at the correct dirs. I can compile a servlet without errors. I can also place a test jsp and html file into the root directory and they both work fine.
    However, now I am trying a test servlet and no matter what I do it gives me a 404. I have a servlet class file called "HelloServlet.class" which I placed into the %install_dir%\webapps\ROOT\WEB-INF\classes directory. I try to reference it using this url:
    http://localhost/servlet/HelloServlet
    Tomcat is configured to use port 80 and has been restarted after adding the servlet class file. Does anyone have a clue why this is not working for me?
    Many thanks
    Marc

    You have to add in the web.xml file that it is in the WEB-INF dir, the information about your servlet. An example:
    <web-app>
    <servlet>
    <servlet-name>HelloServlet</servlet-name>
    <servlet-class>HelloServlet</servlet-class>
    </servlet>
    <servlet-mapping>
    <servlet-name>HelloServlet</servlet-name>
    <url-pattern>/HelloServlet</url-pattern>
    </servlet-mapping>
    </web-app>

  • Basic questions about Exchange Rate Differences

    Hi Experts?
    I have few questions about exchange rates:
    1. Currently in 2007, under what circumstances are exchange rate differences not posted automatically? In the previous version, it was this case when invoices are linked to payment, and manual exchage rate differences had to be run.
    2. What are unrealized exchange rates? and When do unrealized exchange rates occurs?
    3. In account oo logical pinciples, why is there a need to auto reverse Exchange rate differences or Conversion rate differences during the opening of a new posting period??
    Much Thanks!
    Warmest Regards,
    Chinho

    Hi Chinho,
    you may find useful info in this wiki:
    [How does SAP Business One deal with Realised and Unrealised Exchange Rate Differences? |https://wiki.sdn.sap.com/wiki/pages/viewpage.action?pageId=60654139]
    & also these 2 EES:

    As a rule, in version 2007 it's the unrealised exchange rate differences on the BP side that are relevant since with the introduction of the unified internal reconciliation engine realised partial exchange rate differences are automatically posted. You also use the functionality to post exchange rate differences for FC GL accounts at a particular execution day.
    All the best,

  • [SOLVED] Basic question about x2go, freenx, etc. compatibility

    My goal is to simply enable remote desktop on my soon to be headless server. Given the number of posts here at Arch explaining the trouble with freenx and the Arch support of x2go, I'm confused there is not more talk about their compatibility. And as I've just discovered, they're not:
    "Various open source terminal server projects such as x2go also use the NX protocol; however, x2go is not compatible with other NX servers and clients." (NX Technology)
    This leaves me in a bit of a pickle. CentOS doesn't support x2go, and Arch doesn't support freenx. What's the best interoperable solution then? Either a sever app which supports x2go or a client app that supports NXX?

CentOSers are very persnickty about how you're supposed to maintain your system in terms of non-core packages etc. etc. And x2go is not coming up in the forum, wiki, or in the repositories (via the commanline tool yum). Read the response to my question about installing vim7.4. Hell, you can do _whatever you want_ to your system, but that doesn't mean anyone's going to help you when you run into trouble.
    That comment strikes me as perfectly reasonable. The comment is pointing out that you are trying to use the wrong tool to do the job. The tool in this case is the distro - CentOS is not intended to be used in this way (for this job). Of course, if you insist on using a spanner to hammer nails, you are free to do so. But you can't really expect your local DIY shop to help you use the spanner when the nails don't go in straight rather than suggesting you use a hammer instead.
    It is just like somebody who comes here and asks how they can stick with a known-stable set of packages while getting security updates. That's not what Arch is designed for so if you try to use it that way, you'll have a hard time. Of course, you are free to do so if you wish. But if you ask for help, you'll be pointed to another distro because that is the right answer.
    It has nothing to do with being "persnickty". The answer is the most helpful answer somebody can give you.
    Note: I'm assuming the description of CentOS, Fedora etc. is correct. I know the description of Fedora to be correct but I don't actually know anything about CentOS. But on the assumption that description is also correct, that answer is the most helpful answer somebody could give you, even if it is not the answer you wanted to hear.

  • Best Practices: Question about Passing DataSet to Crystal through C#

    I have used the tutorial provided by Business Objects and have successfully passed a dataset from C# code to Crystal Reports.
    I have a few questions about "best pratices" though.
    It appears that when passing the dataset to crystal then you no longer have the ability to put SQL Expressions in the report anymore otherwise errors will occur.
    So, I'm trying to come up with a way to have a custom field in the SELECT statement and have it show up on the report as a field. So, in the below example I created a custom SQL field called TIMES7 in the query.
    "Select CLM_ID, CLM, PAID_111X, *(PAID111X * 7) As TIMES7*_ From WIKI.MULCRICKET WHERE CLM_ID < 5"
    If I create a formula field in Crystal and set it's value to {MULCRICKET .TIMES7} then it works like a hybrid SQL Expression at run-time.
    This does work but has issues because the database field doesn't really exist in the design environment which causes error when the formula is saved. But it does work at run-time.
    I was wondering if their was a best practice for this?

    So why are you using a formula that doesn't work? If it errors in the designer it's telling you it's not supported.
    Drop the formula into a filed and hide it if you don't want it displayed, this way it gets into the record selection formula.
    "Best Practices" is don't use formulae that won't verify in the Designer. "If it doesn't work in the designer it won't work in code"
    If you need to add an "unknown" field at run time then use RAS to insert the field.

  • Some questions about building  a plug in

    Hello,
    1.I'm trying to build a plug in ( for EM12c release 2 ) for my standalone java application - which exposes mbeans whom i want to collect some metrics with.
    It's been a while since i started to build it - and I asked quite a lot of quesions about it - because the documnets supplied with the EDK and
    the books ( ProgrammersGuide, ProgrammersReferece and the README file ) are not very clear to me ( I'm a newbie with EM in general .. )
    So far some of the questions got answered and were very halpfull with this long process. BUT, there are some questions that nobody answered yet.
    I'm quite "stuck" with it. I'm talking about the questions in : Re: A question about updating metadata files in plug in
    I have a deadline for this plug in ( which is very close ..) so this the reason I post this new message.
    I will appriciate any help about those questions .
    2. Regarding the above, ( hoping to have an answered soon ..) I'm trying another way to buils this plug in:
    In the README file there is this section( 3.6 : using MPCUI ) . I read the programmersReference ( chapter 8 ) and followed the instructions both in the README file and the ProgrammersReference .
    For a begining, I just wanted to modify a small thing in the example supplied ( Demo Host System ) just to get started with something .
    So i modify the file which contains the label ' Select member ... ' ( i don't remember the name of the file since the project is in my office , and I can't copy/paste ..- I think the the file icontians the name ' ConfirmationTarget .xml - it's one of the pages seen while adding a target ) .
    I i changed it , i build the project ( using FlexBuilder) but did not use ANT as it's says in the README - the eclipse IDE build this file automatically
    ( HostSystem.swf  in bin-debug dir as it says in the README ) . I copied this file to stage_dir/oms/metadata/mpcui .
    i build a new plug in ( i incremented the version of it ) - no errors, everty thing was fine .I also copied this file to the oms server ( it wasn't there before )
    and than run the commad ' emctl register oms ...' as it says in section 3.6 - and o got 'Success' eventually .
    Now, when i opened the EM console , hoping to see tge change i made ( again , it's just a change of the title of the step while adding the target , and adding another menuitem to the 3 item that were alreay there ( CPU, FS, etc ) .
    I believe wad i did is right- i mean changing in the right file and place ( there is no title like like this in any oter source file in the whole project )
    but still, I didn't see any change! it seems execatly as it was befoer the change ..
    Any idea?
    Thanks.

    Regarding your question #2. Please read my response here carefully as it covers a number of different issues.
    1. Ant is not required to build the SWF file in your plug-in. It is an OPTION. Section 8.27 describes the different development options using either Ant or FlexBuilder.
    2. You do NOT need to ever copy a SWF file to any location under the OMS runtime. You need to include it in the stage area and then either build an OPAR or use emctl to incrementally update the deployed plug-in. It has to either be deployed as part of the plug-in deployment or updated incrementally using emctl register oms metadata. Section 8.27.2.6 describes the specific steps to do this incremental update.
    Steps to update the SWF associated with demo_hostsample. These are covered in the README and in chapter 8.
    1. deploy the demo_hostsample plug-in as described in the README
    2. create an instance of the Host Sample target type through manually discovery (Add Targets->Add Non-Host Target Specifying Properties)
    3. using the demo_hostsample.zip project in Flex Builder, modify some part of the code, for example, modify the line containing label="Current Status" to label="My New Label"
    4. rebuild the SWF, to be sure you can to a Clean build of the demo_hostsample project
    5. ensure there is an updated copy of the HostSample.swf under demo_hostsample\mpcui\bin-debug (NOT bin-release, unless you Exported A Release Build)
    6. copy that updated HostSample.swf file to the location on the OMS machine where you unzipped and built the OPAR for the demo_hostsample plug-in
    7. cd to the stage/oms/metadata/mpcui directory and replace the current HostSample.swf with the one you just built (BE SURE ITS THE UPDATED FILE)
    8. execute the command "emctl register oms metadata -sysman_pwd sysman -pluginId oracle.sysman.ohs -service mpcui -file demo_hostsample_uimd_swf.xml (BE SURE TO USE THE CORRECT sysman_pwd)
    At this point you should be able to go to the homepage for the Host Sample target you created and see the changes.

    I have many questions about this program, but let me ask this one first:
    In the TrueFalseQeustion class, why are there so many constructors? What is the purpose of setting some of the variables to default values?
    Thank you very much!!!

        public void addAnswerChoice (String answerChoice)
            String ansChoice = answerChoice;
            questionText += "\nansChoice";
            possibleAnswers = answerChoice;
        public void printAnswerChoice ()
            System.out.println (questionText);
    } I don't understand why the assignment wants me to build a method in the MultpleChoiceQuestion class to store the potential answer choices, I can make the program display the potential answer choices by including them in the questionText as following in the QuizDriver class
    Question x;
    x = new MultipleChoiceQuestion("What is the color of the car\na.Red\nb.Green", "a. Red", 3);
    t.addQuestion(x); I don't know how to allow the client to construct the list of answer choices one at a time(add one potential answer choice by calling the addAsnwerChoices() method once)
    Here are a few original sentences of my assignment which describe what I should do with the MultipleChoiceQuestion class
    Using TrueFalseQuestion as a model, develop a new MultipleChoiceQuestion class that can be used to represent a problem where the user must select one of several answer choices (e.g., "Select answer (a), (b), (c), or (d)."). This new question type should have all of the same externally-visible functionality as TrueFalseQuestion, except that it must:
    maintain a list of potential answer choices
    provide a method that allows the client to construct the list of answer choices one at a time (i.e., the client should be able to call an addAnswerChoice() method to pass a new answer option to the MultipleChoiceQuestion.)
    display (as part of the question text) the list of answer choices with appropriate letters ("abcd" instead of "0123") I don't understand what these sentences mean.
    1. "Maintain a list of potential answer choices"-- this reminds me of the getPossibleAnswerChoice() method in the TrueFalseQuestion class
    public String[] getPossibleAnswerChoice ()
            String[] possibleAnswerChoice = {"true", "false"};
            return possibleAnswerChoice;
        }I wonder that if the potential answer choices I have to store in the MultipleChoiceQuestion class are only letters "a", "b", "c", "d", etc, or include the answer text coming after the letters(eg. a.Red, b.Green)
    2. "provide a method that allows the client to construct the list of answer choices one at a time". How do I achieve the functionality "one at a time"? Do I need to pass the input of the client (a potential answer choice) to the variable of the method which stores the list of potential answers?
    3. "display (as part of the question text) the list of answer choices with appropriate letters". My question here is that: When the client type in one possible answer, should I append it to the variable questionText? (So I use the questionText variable in the methods of the first and second steps)
    Thank you very much for your nice help!

  • Questions about the content of download meeting recording .zip file

    I tried posting this on the resurrected Connect forum, but my Adobe ID wasn't recognized there....
    Concerning the files that are included in the .zip file of the meeting recording that can be downloaded:
    1) Is there any documentation describing the files and their contents (i.e. what each file represents, what each XML element and attribute in those files represent)
    2) Are there any files that capture mouse movement on a shared desktop?
    Thank you!

    Hi Sean,
    Regarding your first post:
    Thanks Jorma! I don't have access to an FMS build at the moment but I'm quite certain it's there. As for contacting Jaydeep, I am 90% sure he authorized us to broadcast his email on here if folks had questions about the tool, but, in the case that I'm wrong and he didn't - I'm going to double-check first.
    Regarding your most recent post..
    "To be clear, the most critical goal I'm trying to accomplish is to create an automated process that will download the recording meeting at its highest quality in a consistent and reliable manner".
    I personally believe this is possible; unfortunately, I haven't seen it done yet. If your recording contains:
    - audio
    - a camera feed
    - screensharing
    Then I think you might be able to get this going. If it contains shared content, like a shared PPT, this gets trickier.
    "To do this, of course, I have to reproduce some of the functionality that Connect provides, starting and combining video and audio streams according to the instructions in the control files."
    Exactly right. If your recording didn't contain shared content, then all you've got on your hands are a bunch of audio/video files that you could edit together as you wanted with your favourite video editing tool. If it contains shared content, here's (at a high level) what's happening.
    For shared PPTs or FTContent files:
    First (for version 9 recordings only), Connect reads the information on the Shared Content's location and SCO within mainstream and indexstream and validates it before loading it. I don't recall this happening to the same extent with version 8 or earlier, but maybe it was. Now, if the content is validated (ie. Connect can find it) the share pod will display as black, if it doesn't, you get an empty pod with an message like "No content is being shared" or something like that.
    Connect then looks at the actual FTContent file, and loads the content that is to be shared using the file path and sco ID listed in here. It's important to note that the SCO ID and file path in here will likely not be the same as the original file you uploaded to your room, it's a new SCO id (I believe SCOs of this type are called referenced scos) and new path.
    Now...if I was going to build some sort of player which would play all these files in one screen to make a recording...I might not want to use Connect's code here. If you know the file path to the shared content (from FTContent), you could easily view it with the content URL (conveniently also in FtContent). I'm not a coder, but I'm envisioning something like Presenter's GUI where you've got the presentation's content in the main area, and a video file (if there is one) playing back on the side.
    Anyways, food for thought if you want to try to go about this. Connect recordings are incredibly complex and they come with a big learning curve, but if you can make sense of them the knowledge is quite valuable.

  • N00b question about the ABS

    Hey, I am new to Arch and I'm about to install it on my machine (used it a bit in a virtual machine) and I have a small nooby question about the ABS.
    According to the wiki: https://wiki.archlinux.org/index.php/Arch_Build_System
    "Running abs as root creates the ABS tree by synchronizing with the Arch Linux server."
    Does this mean that the ABS tree (not the package) is always downloaded from the official Arch Linux servers, never from any of the mirrors?

    ANOKNUSA wrote:makepkg is part of the abs package.
    You might be confusing that with makeworld. makepkg is included with pacman.
    Anyway, gregor, you are confusing the AUR with ABS. Although, what you are saying is still possible via the source files when looking up a package on https://www.archlinux.org/packages/. But with both, using a program or using the respective page is a personal choice.
    Yup, you're right.  My mistake.

  • Newbie question - general question about e-mail sync

    Hi,
    I have a general question about email sync and BlackBerry smartphones.  Are there any devices that allow email syncing with a Microsoft Exchange 2007 system that do not require the BlackBerry Enterprise server?
    Thanks; sorry if this has been asked before but I was unable to find it in the forums, documentation, etc.  Everything I found assumes that for this kind of environment you will be using a BlackBerry Enterprise solution, but I can't assume.
    Thanks again.
    Solved!
    Go to Solution.

    Hi and Welcome to the Forums!
    If the Exchange server has anything that faces the internet (OWA, POP, IMAP), then BIS can be used to handle email (only email...calendar and contacts require BES to sync OTA).
    Or, a PC, inside the network (but with an internet path) and logged into the email server (using Outlook), can be left running, using the RIM Desktop Software's Desktop Redirector capability to forward  messages to the BB.
    Those are basically the options.
    Hope that helps! Let us know!

  • Question about Lego Mindstorms Capabiliti​es

    Hello, thank you for reading my question!
    I am currently working on the creation of a teleoperated robotics lab. for a introductory robotics course. I wish to allow students to control a labyrinth-solver robot via Labview, with the Lego NXT toolbox. A computer server will be connected to the Lego via Bluetooth, and the student communicates with the server via  a web browser VI (a web published VI). I am interested on the Lego Mindstorm platform but I wanted to ask some questions about its software capabilities:
    *Is it posible via a web VI interface for the student to load a program onto the Lego Mindstorm? My idea is to allow the student to load a VI (or the equivalent of a LEGO NXT ".exe")onto the server, and the server to load the program to the Lego. The Web VI already has some parameters the student can change a simple program execution (see [1]), but I also wanted to give the student the chance of loading their own program for more complicated algorithms.
    Thank you in advanced for your time and patience!
