I've inherited an app from another developer and have added an error notification service, and have now received 1,408 occurrences of an error that I am having trouble getting to the bottom of...
The error is simply:
TypeError: can't dump MatchData
with only non-project frames in the stack trace....
I can see where this error is ultimately occurring in the activesupport gem message_verifier.rb file, but I assume that there's an error in the application or configuration that is causing it originally, and am not sure the best approach how to trace this back to its point of origin on our end. Strikes me as the kind of thing that someone may look at and immediately see recognize it. And advice appreciated....
This is the stack trace:

I am trying to run a cell in Jupyter notebook and getting permission error number 13. The code is
df_manual_testing = pd.concat([df_fake_manual_testing,df_true_manual_testing], axis = 0)
df_manual_testing.to_csv("manual_testing.csv")
The error which I am getting is:

I cannot understand how to change the permission of my file. I think so I will need to change it from root to user, but I am not sure exactly how to do this.
If you are not interested in writing the csv file into the current working directory, you could simply specify the full path of a folder in which you are sure you have the permissions to write.
For example:
df_manual_testing.to_csv("C:/Users/../manual_testing.csv")
However, if you want to write in a particular folder, you can check from the terminal if you have the permissions to write here, using the command ls -lh. Eventually, you could change the permissions using the account of the owner of the folder, with the command chmod 777 myfolder.
If you need more information about file permissions, you could look at this reference.
I am doing Machine Learning Course from Coursera by University of Washington. In which I am using iPython's graphlab. During practise when I execute below command:
sales = graphlab.SFrame('home_data.gl/')
I am getting error.

where i can find home_data.gl in my computer or the problem is something else ..
You need to have your ipynb file and the data file in the same directory for the above to work. Alternatively, specify the full or relative path of the data file in the function
sales = graphlab.SFrame('C:\FULL-PATH\home_data.gl/')
Here is a link to the course reading for how to arrange your directories for the course. https://www.coursera.org/learn/ml-foundations/supplement/IT04V/reading-where-should-my-files-go
Make sure to download the zip folder to the same folder where you will work on this data. For example: I downloaded the zip file to Downloads then I opened my notebook from the download file
Just follow the instructions and download the training data into the ipython working directory.
Go to terminal and run:
unzip home_data.gl.zip
You will see following files in directory home_data.gl:
Now in ipython, run:
sales = graphlab.SFrame('home_data.gl/')
sales
which will display the data in tabular format:
I recently installed Rollbar on my to-be Production instance and I see that Rollbar has starting reporting this issue about not finding a WordPress login.
ActionController::RoutingError: No route matches [GET] "/blog/wp-login.php"
I searched through all my code and dont find any references wp-login.php and the stack trace is not helping either. Would you know where this might be coming from?

This is just the random background noise of the internet - scripts wander around looking for known security holes (in this case, one in WordPress) that their human might want to exploit. If someone ever puts your link into an MS Office document, you'll also see weird OPTIONS requests.
It's common to configure error reporting to ignore RoutingErrors, though of course there are pros and cons to that. It lets you ignore this noise, which can trigger false alarms, but if you ever actually render a bad URL, it can go unnoticed.
I just experienced my app having errors on every page load or almost every page load. A restart cleared out all the problems. Here is what I think happened.
The first error, was "IOError: could not reopen: null"

What cause the initial problem?
weird stuff such as these are likely caused by Rails not being "absolutely" thread-safe (even on MRI but it's more obvious on JRuby since it's "GIL-free") ... Rails.logger.silence and related have not been 100% thread-safe https://gist.github.com/kares/9374772 I've dealt with similar issues (on JRuby on Rails) since 2.3 and there sure were attempts to fix this but somehow the same silencing logic keeps getting back.
the whole silence_stream(STDOUT) {} code (that your trace reveals), I would guess, might end up in a similar "unpredictable" state. I would try patching kernel/reporting.rb so that the stream silencers do nothing (I've updated the gist as well).
I am trying to work with 1 GB XML and DTD file with Erlsom.
The problem is that parse_sax throws an exception becuase it cannot work with DTD file.
Basically i don't need this information so my question is how i tell the
sax_parser to just ignore this?
or even to use try and catch and when the error got catches then to skip this place on the file and continue from there.
This the exception:
** exception throw: {error,"Malformed: unknown reference: uuml"}

The problem is with "uuml" because in the XML file its apear with ü
Thanks for your help.
Hit the same error and found this in the ErlSom docs under limitations of the sax parser:
It doesn’t support entities, apart from the predefined ones (< etc.) and character references (&#nnn; and &#xhhh;).
