As there is no one knows the answer and I somehow figured out how to do it by myself, I think I'd better leave something to help other people.

SECMARK and SELinux are highly coupled, You must define the SELinux Context first, then you can use it in iptables/nftables rules.

The way to define an SELinux is to create a user-defined SELinux ruleset, aka .te file, then compile and install it on your machine. After that, your iptables/nftables may proceed normally with the command above.

Ubuntu is one of the most popular Linux dist nowadays but noted that Ubuntu DO NOT Pre-install SELinux, and AppArmor did not support SECMARK Until Jan 2019, so if you want to use SECMARK on Ubuntu, uninstalling apparmor and install SELinux is probably worthwhile.

And if you want to use SECMARK between systems, please be advised that you need to install policies on both systems.

user_id seems to have an index that forces the field values to be unique

But in your users.json file, there is no user_id field. So when importing the data it creates the field with a null value for all the users. And since the field, as to be unique you have this error dup key:

So to fix this, you have to remove the index on the user_id field. The identifier of a document is named _id in mongodb

You can parse the string to date using $dateFromString

Example here with only one field to read easier.

Mongo query is like this:

After doing a bit more research, the answer to all of these questions...is yes!

Given that Microsoft states that all of private application hives loaded from RegLoadAppKey must use the original handle obtained when opening the hive, I was very curious as to how Visual Studio was achieving this, considering I couldn't see any references to such a handle anywhere, yet when I stepped over registry functions in WinDbg, Process Monitor reported that the private hive had been accessed.

After stepping into these functions I discovered that actually Visual Studio detours all of the Win32 registry functions to its own special handler that determines whether or not it needs to redirect the function call.

As such, we can conclude

• Any attempts to access Visual Studio registry keys will automatically be redirected to Visual Studio's private application hive, if required

This still leaves us with the problem of having to construct the root Visual Studio key in the first place. As it turns out, you can use the VSRegistry.RegistryRoot method to gain a reference to various configuration stores (although only user and configuration types are actually supported)

And so, we can get a reference to the user's configuration key via

I suppose you are not doing JOINS or some other heavy transformations in your insert overwrite query and skew is really happened during insert. Because if you do then question should be not about insert.

Try to add distribute by batch_id to your insert query and re-run. If still running with skew then check your data. There are too many data for some particular batch_id or maybe you have a lot of nulls. There are different approaches of how to deal with skewed data. One of them is to filter out skewed keys and load them separately. Check long running reducer logs on job tracker, it will give you more information about where is a problem.

One way is to not name your windres output files with a .o extension. If you choose a different extension, you won't have this problem.

Another way is to use static pattern rules for the windres targets:

You are applying (lambda (x) (x x))(lambda (x) (f (x x)))
Do the application to get (lambda (x) (f (x x))(lambda (x) (f (x x))
Notice the left lambda creates 2 copies of its argument, which is the right lambda.

So I've managed to successfully create a site, programmatically, and here's what I did:

First, forget about writing a repository (platform) webscript. Creation of sites in Alfresco is done by invoking a Share module, so you'll need to implement either a page, or custom menu item to create a site. I was also getting a lot of problems with authentication, but if you log in to the system via Alfresco Share, and in your Javascript, use the provided Alfresco Ajax request, then authentication shouldn't be a problem.

Here are the components I used:-

1. Create a Share page to create your site. In the Freemarker template (.ftl) add a form to collect the site details.

2. Attach a button on the form to the following Javascript function. Note that I cobbled this together from various code fragments on the web, so it could use some cleaning up. But it basically works for me -

don't do foreach. When you get the response from the http call just do
