            "this class is not key value coding-compliant" when using SideMenu pod in interface builder
            Asked 2021-Jan-05 at 15:07

            I am using SideMenu pod. While the app is functioning normally I am getting an error of

            Failed to set (leftSide) user defined inspected property on (UINavigationController): [ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key leftSide.

            In the attribute inspector, I have leftNav set to ON. I am not sure what am I missing here, or what to do with the leftNav key. I do not have any unwanted connections.

            The “this class is not key value coding-compliant” error almost always means that you are trying to set a property of a custom subclass in your storyboard or XIB file in Interface builder, but forgot to change the class of your object to the custom class. It's easy to get this error if you use "user defined runtime attributes" to set properties on your objects, but don't set the class of the object correctly.

            I'd have to look at the project - and specifically it's Storyboards/XIB files, to find the problem, but that's very likely what's going on.

            Best way of monitoring multiple log files
            Asked 2020-May-19 at 17:12

            I need to know what is the best tools to monitor multiple log files suitable to my needs.

            What I need :

            • Send and monitor multiple log files at once
            • Support real-time viewing
            • Better graphical User Interface whenever possible
            • Capable of searching or filtering the logs
            • Setup with minimum effort whenever possible

            I have gathered some tools, they are :

            1. multitail, a simple multiple log files viewer, but I prefer a better graphical UI
            2. lnav, it's like multitail, but I don't know what's the pros and cons between the two
            3. FrontTail, I think this is much better than the previous two
            4. GrayLog, I have used this once, it has great searching or filtering features, but it was setup by someone, not sure if the setup would be complex or not
            5. LogStash, I never use it, but many people say it's great, but is it easy to setup?

            the source of logs coming from these :

            • gridpane.com log
            • nginx access log
            • nginx error log
            • PHP error log
            • MySQL query log
            • MySQL error log

            I finally found the one that suits my needs.

            I'm sharing this in case anyone who wants to use the same solution.

            Thanks to sourav19, I followed your advice, even though it took me 8-10 hours to install and configure everything, but it's really what I want.

            I had to buy a Digital Ocean droplet, cost me $20 to get a 4 GB of RAM, but I think it's much cheaper than buying the other log monitoring applications which are way too expensive.

            Before installing docker, we have to enable Virtual Private Cloud (VPC), we will use the provided IP Address for our docker containers, so they can communicate between each other, by following this article.

            I used a dockerized ELK, link is here

            All we need to do is to clone the dockerized ELK to our server, and then go inside the cloned folder, and build the Dockerfile

            How render form with previously entered data when validation fails
            Asked 2019-Jul-13 at 13:55

            I'm doing www.theodinproject.com Project: Forms. If the new User fails to validate, it should render :new with the previous entered data. My code works to save new users and it render :new when validations fails, but the previously entered data is missing.

            Tried to research the solution myself but couldn't resolve it. I apologize if a similar question had been posted.

            You are never setting the input's values. I'd suggest you use rails' form helpers like form_for and the rest. https://guides.rubyonrails.org/form_helpers.html#binding-a-form-to-an-object

            We are having trouble with simple updates on a single table taking a long time. The table contains ~40 Million rows.

            and the job runs every day that truncates the table and inserts new data from other sources in that table.

            autotools - crosscompiling and building native intermediate building programs
            Asked 2017-Apr-28 at 15:51

            i am right now working on restructuring the autotools project lnav to be buildable with yocto. That means lnav itself has to be cross-compiled, while some helper programs have to build natively.

            I already found this thread this thread, but the first proposed solution does not work, while the 2nd is heavily invasive on the project structure.

            Can somebody give me a hint how to solve this? Maybe tell me which AC/AM Macros do the job or where to get a good example.



            Answered 2017-Apr-28 at 15:51

            If you need to build different pieces for different execution hosts, then the cleanest way to go about it is to build the build tools separately. One of the answers you linked describes a way to do this. If you have a well-written Autotools build system, however, then you might be able to tackle this differently, by leveraging out-of-source builds. This can be scripted.

            Create a directory within which to build the tools. In that directory, configure for the build system (path-to-source-dir/configure), and then build (just) the needed tools. Then in the source directory or a different out-of-source build directory, configure for the cross-compilation by specifying the appropriate --build and --host triplets to configure, copy or link the already-built tools into the build directory, and perform the rest of the build.

            If the build system is especially carefully crafted, then you may need to overcome provisions for different executable extensions for the build tools on different hosts. If you need to do this and you're planning to script the two-stage cross-compilation anyway, then you can probably handle the issue when you copy/link the tools; that will avoid any need to write special support for it into the core build system.

            To support cross-compilation in general, configure.ac should use the AC_CANONICAL_BUILD and AC_CANONICAL_HOST macros, and the build machine will need to have an appropriate cross-compilation toolchain installed.

            Error while running Sinatra app on Cloud 9
            Asked 2017-Mar-29 at 16:21

            I am using cloud 9 IDE to follow this tutorial. How can I run Sinatra on Cloud 9 ? I created a blank workspace in cloud 9, ran gem install from command line. But running Sinatra from command line doesn't work. I notice it flags Important: use ENV[PORT] as the port and ENV[IP] as the host in your scripts! after starting the server. How can I make this work? Thank you in advance.



            Answered 2017-Mar-16 at 12:51

            As the c9 window says "...; make sure it's on port $PORT with $IP as the IP address", this is, don't replace $PORT or $IP with your own values, they're values already defined, you can check it using echo $IP && echo $PORT.

            Try running ruby hi.rb -p $PORT -o $IP within your Sinatra project directory.

            You can also define the port and ip as environment variables as the flags you noticed say running the export PORT= && export IP= command, and then access to them within any ruby file as ENV['PORT'] or ENV['IP'].

            Note: For some reason when I use the route get '/hi' it didn't work running on c9.io, but it did it correctly in my local machine, if you have the same mistake try just get '/'.
