Windows 10 platform
Using the notes "https://docs.corda.net/docs/corda-os/3.2/getting-set-up.html" I failed to start the Cordapp Example nodes as documented.
After issuing the command "gradelw deployNodes", I see 7 command windows start. Some show the text "Listening for transport dt_socket at address: nnnn". Some show this plus more output up to "Starting as webserver: localhost:nnnnn", some showed a fuller output with "Cordapp" styled text, and some no output at all.
When I browse with Chrome to "http://localhost:10007/web/example/" I see no rendered page.
Can you hint me as to how to proceed?
I have a fuller doc for this issue, but cannot attach it here.
Many thanks for any thoughtful feedback.
Regards
Dave Harrison

Apologies if I've gotten the terminology wrong. I'm following the vignette on R selenium to the letter, and so I'm using version 2.53.1 of the standalone firefox web driver in docker:
docker run -d -p 5901:5900 -p 127.0.0.1:4445:4444 --link http-server selenium/standalone-firefox-debug:2.53.1
I'm playing around trying to fetch my student data automatically from my university, and so far I've managed to choose the correct university from a list, logging in with my username/password and clicking the "my education" button. Here I get stuck. It doesn't matter if I click the link in the debug tool (that would be tightVNC Viewer) or if I tell the script which links should be clicked. I end up with an empty page with just the word "filter" on it:
This doesn't seem to happen when I use regular firefox:
Also, for some reason the first page is in English why the second is not.
Since the issue remains the same regardless if I use commands or the debug tool the issue might be the web driver I think. Should I still be using version 2.53.1 or is there a newer, better version out there?
Which one in that case?
If I'm on the wrong track and the problem is something else entirely then please tell me so!
I've been trying to build a CordApp and I downloaded the template from GitHub. The code that I've written is available on the following link:
https://github.com/shanmukhipriya99/taskcordapp
When I'm trying to run gradlew.bat deployNodes in the cmd terminal, this is what I got:
[gradlew.bat deployNodes]
Then when I run build\nodes\runnodes in the cmd terminal, this is what I got:
[build\nodes\runnodes]
Then I have three other terminal windows opening-up, they load the Corda part, show some red text that says something about the developer mode and all the node terminals get closed automatically before I'm able to read the entire text.
Can someone please help me in figuring out where I'm wrong!?
Thanks in advance!
It looks like you have had successfully started the nodes all in one terminal. I am not entirely sure, if this is the only issue, but I have seen this issue before. This is caused by lack of permission of the Terminal.
I have seen it happened for both Windows and Unix/Macos users. To resolve it you might need to grant the permission to Terminal manually.
If it still does not work out, I would actually suggest the alternative quick fix that Ashutosh mentioned in comment. Open a new tab and go to the root folder of each nodecd /build/nodes/XXX, and start the node manually via java -jar corda.jar
Im trying to complete the very first training module offered by MS. Something Im missing that isn't detailed on the documentation of the training.
These are the instructions I'm following
https://github.com/MicrosoftDocs/mslearn-aml-labs/blob/master/labdocs/Lab01.md
All good until I have to run the second command defined on the notebook called
"01-Getting_Started_with_Azure_ML.ipynb".
And yes I entered the device login code as the instructions indicate.
Look at the attached screenshot of the error returned after running the command of the notebook.
Opened a case with Microsoft. They noticed is an issue affecting their VM servers.
This is their reply:
Hi Marbin,
Hope you are doing good. I had discussed this with our team as well. This was a known issue with workspace names with capital letters. So, the workspace name ‘ML_Battlefield’ was creating the issue. This is fixed in SDK version 1.3.0.
In the compute instance notebook, we can update the SDK version to: pip install --upgrade azureml-sdke
I'm trying to get XCode 4 to symbolicate a crash report. I've googled and followed this link (https://github.com/chrispix/symbolicatecrash-fix) but get stopped. The instructions say "To fix your iOS crash report symbolication, move /usr/local/bin/symbolicatecrash aside and copy in the version in this repo." Well, I cannot find "/usr/local/bin/" on my Mac. I'm new to the Mac world, so I'm sure there's something I'm not understanding. If "/usr/local/bin/" doesn't exist, then where is XCode 4 finding symbolicatecrash? Please point a newbie in the right direction as I have a lot of bugs to be fixing.
Thanks
Tom
that tool has been relocated to /Developer/Platforms/iPhoneOS.platform/Developer/Library/PrivateFrameworks/DTDeviceKit.framework/Versions/A/Resources/symbolicatecrash in newer version of the SDK
you would run it as:
./symbolicatecrash -A -v [crashlog-filename] MyApp.dSYM
keep in mind this is for iOS only, for OSX see http://developer.apple.com/tools/xcode/symbolizingcrashdumps.html (for the app to contain the symbols "DWARF with dSYM" must be enabled in it's build settings)
you would run it as:
./symbolizecrashlog [application-name] [crashlog-filename] > symbolized.crash
I would like to add that all this usually is done automatically, these manual approaches are for cases when there are issues with the system symbols database as discussed in Xcode 4 failure to symbolicate Crash Log
I would like to have the BlackBerry simulator print to console so that I can debug with out an IDE. I do all my development from Linux with bb-ant-tools and have the emulator running on windows (on a separate computer). I don't have eclipse or the jde on windows, just the emulator.
--edit 02/28/10
After much searching it appears I need to connect to the simulator to jdb and to do that I need to find the default JDWP port or how to change it with out the JDE's JDWP application. I am looking at possibly port 8000, I hope it isn't randomly assigned.
--edit 03/02/10
Correction, the JDWP application is required as it is what you connect the jdb to by jdb -connect com.sun.jdi.SocketAttach:hostname=host,port=8000 but output is placed in output tab of JDWP making it very unlikely that it can print to a console and be done without the JDE. I would very much like to be proven wrong though.
A couple of things, not sure they will be very helpful.
jdb IS a command line tool, so you should be able to get console out that way.
For Linux, you can use the Barry tools that give you the jdwp as bjdwp command, then you should be able to use jdb
Also, you can get the Simulator to work on Linux by using Wine. I am able to run both the Barry tools and the Simulator on my mac.
I hate writting up such a short not detailed enough answer, but hopefully this will help someone else who will have time to provide more details.
PS: Sorry about no http:// but it seems that I am such a newbie I can't put more than one link on my answer.
