PPPoE problem - solution for review

I'm posting this to save others the search after I troubleshot a painful issue, which wiser types may be able to clarify the background.
Equipment: DLink DSL 504T Gen II; MBP 2008; AEBSdual-n 2009
Problem: Set up new AEBSdual-n, set up security, PPPoE to bridged modem and accept all default networking settings. With correct username & p/w, AEBS fails to authenticate, flashing yellow and generally not responding to Airport Utility very well, even by wired connection...
Solution: Noticed that default DHCP prefix in Airport is 10.x.x.x which is the same ilk as the Dlink DSL 504T. Wonder if the subnets are clashing or something. Try changing DHCP prefix given out by AEBS to 192.168.x.x and all works fine. Note that to achieve this I had to hard reset (power and reset button at once) to restore default settings.
Those wiser than me can look at the reasons, but I wanted to post a likely solution for many others I've read when researching the problem.
Cheers,
Tim

Overall a C- job Some things you did well. Please excuse me for only pointing out the flaws as my time is limited.
You have some bad habits that you need to break;
Icons. They need to convey information to the next maintainer of your code. Is that a flame under a teakettle? Like GUIs the color usage in icons should avoid garashness and help aid clairity. Your file read vi icon uses a glyph I would associate with a error dialog.
Use a project
Tip Strips on every object the user can see on the GUI!
Timing- you have failed to meet spec on preserving the elapsed time if rain occurs durring the servicing of a zone. You need an elapsed timer with a pause feature.
Wire bends. Enough said?

Looks pretty clean, but I have not looked at it in detail.
Here are a few notes:
Isn't this supposed to be inside a project?
I hate it when diagrams are maximized to the screen (main VI and file I/O vi)
You have an existing log file and if I run the VI, new data gets appended. The problem is that the existing entries have a comma as decimal seperators, while the new entries (run in the US) have a decimal point. This could confuse a program that later might analyze the logs. You should decide on a wordwide format.
To blink the pilot, you can create a direct property node for the button inside the cluster (right-click button on the front panel...create....property node. see image below). No need to get all control references and index out one. (even if you get all the boiler control references, that only needs to be done once outside the loop and not every time it is needed.
As has been said by jeff above, terminals of subVIs should be on the toplevel diagram, and not buried inside case structures.
In the file I/O subVI (open file case), you only handle error 7. Shouldn't you handle all errors somehow? For example if the file is "read only", you would get error 8.
It would seem more easy to format "event" and "event data" into a single string in the main VI. Now you only need one feedback node to see if anything changed. The combination of strings and numerics can easily be done with single formatting statements.

Sample CLD (Boiler Controller) Solution for Review

Hi,
I have solved the Boiler Control example, as part of my CLD practice.
Can you guys please review it?
I couldn't meet the timing deadline but I think I can do it with some practice.
Also please excuse the documentation part. I hav done almost nothing on that as of now.
I would like to see comments on architecture, functionality, code readability, etc.
Thanks in advance.

I'm studying for the CLD myself and haven't passed it, so take my comments with a grain of salt.
A few suggestions. They're all very minor.
1) For your next practice, take the last 10 minutes of the 4 hours and do documentation. Those are fast, easy points. It's even better if you document as you go - just type a quick description of what you're doing in each frame, and add documentation to your VI Properties (especially your main one).
2) This is very minor, but I noticed a lot of coercion dots. A Quick Drop and Ctrl+I will clear those out quickly.
3) I think you should hide your debug indicators for State Q. At least move them off to the side, away from the desired front panel.
4) Shift cluster should definitely be a typedef.
5) Is there a reason you used a "File Directory/Info" instead of a "Check if File Exists" function? This is more a curiosity question than anything; the way you coded is functional, but sort of indirect.
6) I'm not sure if the exact right values are writing for the log file, I see "6/27/2012::10:29 PM,Pilot Proved,29.59" as a line, and I would expect the Pilot value to be >30?
I think barring a slight lack of documentation, it looks great. It's very organized and it's clear in every state what you're doing.
I hope you pass! Good luck on your exam!

Sample CLD (Car Wash) Solution for Review

Hi,
This is my first time posting. I am studying to take the CLD and I have attached my solution to the Car Wash sample exam (LV2011) using a PC-Events architecture. I ignored the time constraints for now to see where I stand as far as functionality and style. I tried to be thorough (not creative) with documentation as well. Any feedback would be greatly appreciated.

Great, thanks for the feedback. Any chance you can show me how you use the queue naming and the sub vi in this way? I've played with it but my attempts do nothing to improve the BD.
Thanks
Sure, Here is a copy of my PC loop (events) template with the consumer loop as a sub-vi (Type Defs disconnected)
(NOTE: my template contains vi documentation template as well) This won't save you on the CLD exam since the shipping templates are all you can use. But having your own for "Real Life" sure speeds up programming time.

Hiss...Problem & Solution (for me)

I was trying unsuccessfully to eliminate hiss from audio recording, unsure if it was mic, mixer, cables, sound card, software-related or what. I have been using both line-input and USB input devices. My old mixer died and I took my laptop to the music shop and tried a bunch of options. The USB-connected M-Audio external sound card created just the same hiss. The line-input mixers produced NO hiss (at least not the Compact 4 that I got). Beware USB input for audio.

I'm using the sound card in my 12" PowerBook and, with the Compact 4, it gives me very good sound. I noted hiss when using the USB Griffin i-Mic as well. The USB issue may well be a function of the laptop...however, I have seen other posts on the web remarking about USB-related hiss. For what it's worth, I wanted to share my experience so that others may not have to bang their heads against the wall trying to figure everything out as I did. I do not claim that my posts are the final answer...just my answer.
Thanks for your responses.

Display color problem - asking for a color solution

So I have this serious problem with my Macbook Pro.
Some months ago I suddenly saw green colors in black area's and pink line colors in white areas.
Text on white background was extremely frustrating to read, since it was surrounded with small pink lines and flickering.
Note this was only near max white and max black areas of the screen.
I found out that it was due to a hardware failure, since slightly bending the laptop (!!) would remove the problem
Attaching an external monitor doesn't show the defect, and booting in Windows 7 (bootcamp) still shows the same screen problem.
Searching the web, it appears that it was a NVidia related heat problem, known to my model, but the offer to get it fixed for free by apple (since it was a known issue) had already run out december 2012 (!!). I think my laptop is about 3-4 years old, and the battery pretty much died on me the first year, probably due to heavy usage and the graphic card getting too hot. There are small sweat/corosion marks of where my hand are placed when typing, on the aluminium, due to how hot my laptop got. It sometimes got so hot I couldn't touch the aluminium on the top left corner near the 1-2-Q-W keys.
Fixing my Macbook is too expensive. Just getting someone to look at it to diagnose it (without repairing it), costs a lot in my country, and we have no official apple store, only authorized resellers. I know it's probably the motherboard, because I tried to unscrew the backlid and gently touch certain area's on the motherboard with a pen, while the computer was still running, to find out where the short circuit was. I only started this kind of trying to "self service" it, because I knew how expensive replacing the motherboard would be (if that was even the issue?).
I have multiple times tried to place something up against the sensitive area's on the motherboard, and then screw back the backlid, to put some pressure on it, which at first worked brilliantly and removed the color issue for some weeks, before it started reappearing. I think the heat from the laptop slowly makes the motherboard adapt, and the problem returns. Extremely frustrating indeed.
I hope I can one day afford a Macbook Air, but until then, I don't want to throw more money after my poor macbook (which I pronbably can't sell anyway, like previous mac's I've owned, the day get a new. It's too worn out + battery got only 5min on a full charge).
I think it's wisest to rather save the money for a Macbook Air, and try to survive until then. Therefor I was hoping someone could help me with a temporary solution.
In Windows 7, using the Nvidia Control Panel to apply color management, I was able to adjust the individual color output values, and thereby remove the the screen issue! Maybe the colors are not as good anymore, but it sure beats not getting a headache after 10minutes trying to read an article.
I tried the same thing on the mac, using Preferences>Displays>Color>Calibrate, but this guide is much harder to use to get a decent result (since only the last 2 options really makes a difference, but changes the colors completely, which I can't change by going back to the first color settings since then it just undos the last step I just did. I'm currently writing this with a very blue pale screen.
I also tried to use ColorSync Utility, expecting to enter values manually, but contrary to the articles I read about using ColorSync, I cannot edit the values in the color profile I created (I can only change the ASCII text input fields). Trying to save the profile gives me the error 'The Document "screenbug.icc" could not be saved.'
I tried to look for alternative color calibration software, but most of them required hardware, or expensive full version to unlock the settings I needed (like SuperCal).
I hope some tech savy users out there that can help me, or at least make my life with my macbook less of a pain.
All help is much appreciated!!
PS: I've been a loyal Mac user since always. Few things I've learned is:
1) Don't buy the first version of new hardware. Wait about a month for reviews, to check for issues. I had a problem with an expensive MacPro that had to be replaced, but luckily for free since it was Apple's mistake. Sometimes Apple products also get minor internal changes/fixes without announcements, to help solve reported issues from early buyers.
3) Take care of you Mac, especially so because you can often sell your used Mac's for quite a value the day you want to upgrade. I've sold about 3 Mac's in my lifetime, for quite a gain, though I don't expect this macbook to do as well, if at all. But it's normally something to be cautious about.
3) Don't order custom configurations from the Apple Store, if you can live without it (+ it's usually crazy overprices). I payed extra to get the NVidia GeForce 9600M, and was happy with it for the first couple of years, but is now causing me all the problems I have today + made my Macbook worthless.
Stick with what the default configuration if possible, as other configurations might not have been tested carefully.

Who exactly is your comment "I am asking you to fix this problem soon" directed at?
Remember that you are posting on a user to user forum so nobody can really help you. If you want to give feedback to Apple, then contact them directly at http://www.apple.com/feedback.
Also, if you have an iPhone 3G and iOS 4.2.1 is the latest software that you can install on your phone, then there is absolutely nothing that anyone can do to fix the problem if you want to install Skype that requires iOS 4.3 - what do you think anyone can magically do?
iPhone 3G is a very old phone now and if you want to install Skype on your phone, then you need to go out and buy a new iPhone - either a 4s or a 5. Nothing more to it. Buy a new phone.

Is there a solution for my "files in use" installation problem with Adobe Reader XI?

I have tried repeatedly to download Adobe Reader XI (11.0.07), but I keep getting a "files in use" message that indicates my current version, Adobe Reader 8.1, is using files that need to be updated by the download's set up. The message directs me to close my Adobe Reader 8.1 and then continue, but when I receive it my Adobe Reader 8.1 is always closed. I am tempted to uninstall my Reader 8.1 and then try downloading Reader XI, but I am afraid I could be inviting even more trouble. I should mention the reason I am trying to download Reader XI is a notification I received in my computer's status box that indicates my Reader 8.1 is not working properly and suggests I download the latest version. I discovered the notification after I was unable to open a GIF file attachment. Does anyone have a solution for this problem?

Thanks for your reply.
I tried to uninstall my Adobe Reader 8.1 in safe mode, as suggested above, but received a message which indicated that Windows installer could not be accessed. That was a strange message, because I have not had problems uninstalling programs in the past, and, after receiving the message, I tried uninstalling a different program in safe mode and had no problem doing so. I am now going to try your suggestion.
Honestly, these types of technical issues always leave me so frustrated. I do not have a high technology acumen, and because my laptop is six years old, I cannot get professional help without paying a hefty fee. Thank goodness for this forum. If the solutions suggested here do not work, I guess I will keep my laptop until my Adobe 8.1 gives out completely.
Thanks again for your assistance. I will let you know if it works.

Does anybody have a solution for the NAT problem?

Is somebody's application or Applet able to play any RTP stream behind a NAT Router? Can anybody establish any kind of connection / broadcasting between two subnets? I've got my RTP-Transmitter@public IP (using RTPManager...SendStream.start()), and I try to receive the stream from my local network which is behind a router (DHCP: 192.168....).
I read forums, newsgroups, looked for any solution for days all over the web but I've found nothing. Zero.
What's the secret? Any hints?

Hi
I have the same problem.
I have one appletTransmitter that capture video from webcam and transmit it to other client on internet.
I try to transmit medialocator from appletTransmitter to servlet1 and then save MedialLocator as servlet attribute, then other client can connect to servlet2 that send saved MediaLocator to appletClient.
APPLETTRANSMITTER:
URL url=null;
MediaLocator media=new MediaLocator("vfw://0");
try{
url = new URL("http://localhost:8080/servlet1");
catch(MalformedURLException mue){mue.printStackTrace();}
URLConnection conn=null;
try{
conn = url.openConnection();
catch(IOException ioe){ioe.printStackTrace();}
conn.setDoOutput(true);
OutputStream os=null;
ObjectOutputStream oos=null;
InputStream in=null;
ObjectInputStream iin=null;
MediaLocator mResp=null;
String r=null;
try{
os=conn.getOutputStream();
oos=new ObjectOutputStream(os);
oos.writeObject(media);
//oos.writeObject("Prova Servlet");
oos.flush();
catch(IOException io){io.printStackTrace();}
catch(ClassNotFoundException cn){cn.printStackTrace();}
SERVLET1
ObjectInputStream objin = new ObjectInputStream(request.getInputStream());
MediaLocator ml =null;
try{
ml = (MediaLocator) objin.readObject();
context.setAttribute("media",ml);
catch(ClassNotFoundException e)
{e.printStackTrace()}
But on servlet1 there is a ClassNotFoundException: MediaLocator
What do we think about the solution and exception problem?

My 500 GB can't verify nor repair. I have photoshop work that I need to recover. I would like to know what option would be the best solution for this problem?

You appear to have two issues: 1) a hard drive that is not working properly and 2) files you wish to recover.
Re 1) you need to answer Kappy's questions.
Re 2) does the drive load and can you see your photo files? If so can you copy them to another drive?
Do you not have a backup of the photo files?

My solution for the "Error -50" and/or "Syncing" problem

Hi
After upgrading to iPhoto 5.0.2 I also had the "Error: -50" problem"
How have I solved this problem => also with the help and tips from other forums.
Before the upgrade all my pictures from iPhoto were available on my iPod Photo (30 GB)
After the upgrade of iPhoto to 5.0.2 I received the "Error: -50" every time I tried to synchronize my iPod. Strange, strange, strange, ...
=> first I detected that putting pictures on my iPod starting from a folder (in stead of iPhoto) worked fine.
Trying to change back to iPhoto did not work and no albums where available in the iPod Options view!
=> then I tried to create a new iPhoto library (press and hold Option(alt)-key while starting iPhoto), put some pictures and albums in it ... and even this did not work.
What did I do to solve this problem!
1. I thrashed my iPhoto application (DO NOT empty you trash, because you have to put it back again)
2. I used "Disk Utility" to repair the disk permissions.
3. I put back my iPhoto application from the thrash (same location as before - Applications folder)
4. and did again a "repair disk permissions"
5. then I tried to sync my NEW iPhoto library on my iPod and EUREKA this worked.
6. Then I switched back to my original iPhoto library (launch iPhoto holding the Option key).
7. Tried to sync ... again the same problem => no pictures and albums available in the iPod - Optoins - Photo tab.
=> conclusion : the problem has to be in my iPhoto library
8. after trying many things (such as eliminating albums => trail and error method) I found the cause for my problem.
=> I used KEYWORDS in my iPhoto library with strange characters and had SMART albums using it. In my situation it was the "&" character.
Replacing or removing this character solved my problem. All my pictures and albums were available in the iPod - Options - Photo tab
9. Sync could be started ... Youpi!
After synchronizing my iPhoto library I noticed that not all pictures were available on the iPod. I start looking which pictures that were missing on my iPod. When I found them I wanted to know why they were not synchronized.
I found the explanation in the file "AlbumData.xml" in the "iPhoto Library" folder.
If you open this file with TextEdit and search for this missing file then you'll find that (at least in my case) corresponding path does not exist (any more). And that was the case for each missing file!
How solving this problem?
1. I tried rebuilding the iPhoto Library => launch iPhoto holding the Option and Command keys. This did not work.
2. What did I do?
2.1. First I exported all my Pictures from the active iPhoto Library (Share - Export)
=> VERY IMPORTANT NOTE : all extra info such as "Key words", Albums, ... will NOT be saved!
2.2. I created a new iPhoto Library (launch iPhoto holding the Option key)
2.3. Then I imported all exported pictures.
=> if you check the file paths in the AlbumData.xml file, you'll see that this info is correct!
2.4. At least I recreated (manually) all "Key words", Albums, ... so I had a duplicate of my original Library.
I hope this also works for other people with the same problem.
Greetings
P@nt@ni

Here my solution for the itunes' "unknown error -50" and not showing any albums in the prefs' tab:
1. All rebuilding options in iphoto didn't resolve the problem.
2. I opened the file "AlbumData.xml" in the iPhoto-Library-Folder with a text editor. I figured out, that the problem wasn't in the Albums, but in the "Master Image List"-Section. They look like this:
<key>1741</key>
<dict>
.. titles, filenames, ....
</dict>
After making a backup of this file, I started deleting entries here (you know, the fastest way to do it is to split it always in halves and check in iTunes if the error still exists). After about half an hour I got the problem key.
3. The problem was: Some (curious) white spaces at the BEGINNING of the comment! Curious, because they weren't visible in iPhoto's comment, but I could delete them in Iphoto! I guess they weren't normal space characters, but any special symbols (line feeds? whatever)
4. After that, the -50 error was gone. Now I could see the Album Names. But the sync stopped after a while with a "... file not found...." - error.
5. Again, with trial&error I found out, that 4 pictures in the last 3 months' rolls made this second problem: I just duplicated them in iPhoto and deleted the original ones. So I still don't know why they have produced this error... anyway,
6. Now all of my photos sync well.
.. well, the whole story took me 2 evenings. I really didn't switched to Mac to play debugger for Apple. Do they read these groups here or do I better write them anywhere? They should get those problems fixed asap! As far as I read in the groups, those errors do exist quite a long time?!
My versions:
iPhoto 5.0.4 (263)
iTunes 5.0.1 (4)
OS X 10.3.9
iPod Nano 1.0

iPhones purchased in the US are NOT guaranteed to work with 4G bands outside of North America.
For what crazy reason did you purchase an iPhone in the US if you live in Greece? If your phone needs servicing, it will have to be brought back to the US. You cannot get that phone serviced in Greece.
