kandi X-RAY | LSM Summary
The Liquid State Machine (LSM) (Maass et. al. 2002) is a computational model which uses the high-dimensional, complex dynamics of recurrent neural circuits to conduct memory-dependent readout operations on continuous input streams. This package provides a convenience wrapper for network construction, as well as typical operations on the reservoir. Note that this code does not implement the exact model in (Maass et. al. 2002), but rather a slightly simplified model. This code was used in (Kaiser et al. 2017).

I have problem with my bpf program. I getting error while loading this program. my bpf program is:
...ANSWER
Answered 2021-Jun-15 at 07:28TL;DR. You should check that the pointer returned by bpf_map_lookup_elem
is not NULL.
With the following logs, the BPF verifier is telling you that, when it reaches the dereference of my_pid
, the pointer may still have a NULL value. It thus contains a map value or a NULL value, i.e., map_value_or_null
.

QUESTION
I have 2 DataFrames (PreServices, PostServices) each DataFrame contains Windows services and their running status at a given time.
How does Data look like?
- there is no order of how services names are listed
- PostServices may or not have Names that are in PreServices
- PostServices may have Names that are not in PreServices
I want to create a new column in PreServices named 'final status' and its values should be such that:
- for each Name in PreService if Name in PostServices and State are the same 'final status' == True
- for each Name in PreService if Name in PostServices and State are the not same 'final status' = PostServices['State']
- for each Name in PreService Not in PostService 'final status' = False

I am trying to start slurmd.service using below commands but it is not successful permanently. I will be grateful if you could help me to resolve this issue!
...ANSWER
Answered 2020-Oct-06 at 11:16The log files states that it cannot bind to the standard slurmd port 6818, because there is something else using this address already.
Do you have another slurmd running on this node? Or something else listening there? Try netstat -tulpen | grep 6818
to see what is using the address.

I wanted to use eBPF's latest map, BPF_MAP_TYPE_RINGBUF
, but I can't find much information online on how I can use it, so I am just doing some trial-and-error here. I defined and used it like this:
ANSWER
Answered 2020-Sep-28 at 03:52You are right, the problem is in the size of BPF_MAP_TYPE_RINGBUF (max_entries attribute in libbpf map definition). It has to be a multiple of a memory page (which is 4096 bytes at least on most popular platforms). So that explains why it all worked when you specified 64 * 4096.
BTW, if you'd like to see some examples of using it, I'd start with BPF selftests:
QUESTION
Reading about LSM Trees in several blogs I have wondered how do actual implementations deal with concurrency in when receiving several simultaneous requests to insert values which would modify the in memory structure of the MemTable.
- When inserting a value to the MemTable (which most seem to indicate is a tree)
- How does it deal with multiple insertion requests at the same time?
- How does it deal with read/write races?
- Does it use a simple R/W lock mechanism ?
ANSWER
Answered 2020-Sep-22 at 23:22In Cassandra, mutations with the latest timestamp wins so it can handle thousands of concurrent insertions and there is no race to deal with and there are no locks required.
The SSTables are immutable -- they never change once written to disk. But the data can be rewritten by compaction threads which merges SSTables into new SSTables depending on the compaction strategy defined on the table. Cheers!
QUESTION
I'm experimenting with Linux Security Modules, trying to make one.
My main source of knowledge about how they're supposed to work are mailing lists archives and the existing LSMs' sources, plus the few pages about them in the Linux documentation.
I understand that there are two kinds of LSMs.
- Exclusive LSMs like SELinux / AppArmor, which have the
LSM_FLAG_EXCLUSIVE
flag set in their LSM definition. - Non-exclusive LSMs like Yama, capabilities or lockdown.
Browsing the source code of all these LSMs, I figured out non-exclusive ones never make use of security blobs. On the other hand, exclusive ones make heavy use of them.
For instance, see the AppArmor LSM definition, and the one for Yama.
So, can non-exclusive LSMs specify blob sizes and use this feature ?
Trying to find an answer, I explored the framework's source to see if maybe security blobs were switched between each LSM hook call, I guess that would allow each LSM to only have access to its own blobs and not those of another LSM.
However, we can see here in the LSM framework that it is not the case.
If my LSM declares blob sizes, can I use the blobs if my kernel also have SELinux, for instance, enabled ? Won't the structures from SELinux and mine overlap ?
...ANSWER
Answered 2020-Aug-22 at 22:43Alright, I found the relevant code in the LSM framework.
QED: Yes, all LSMs can use security blobs as long as they use the sizes structure as containing offsets once the module is ignited.
Explanation:
When you define your LSM, you use the DEFINE_LSM
macro followed by various informations, including a pointer to a struct lsm_blobs_sizes
.
During its own ignition, the LSM framework (which is mostly implemented in security/security.c
) manipulates your structure in a few operations.
- It stores, in its own instance of the structure (declared here), the sum of all LSM's security blobs sizes. Precisely, looking at this stack trace:
QUESTION
I need to read the list of users in the Azure active directory. The client has created a Graph API application but they do not want to share the client secret of the application, instead they asked us to use the Key vault. How to access from the node.js application the key to retrieve the list of users?
I tried the below one but gave error and I am not sure how to authenticate.
...ANSWER
Answered 2020-Aug-10 at 17:13All you need to do is follow the below steps:
- Create an App in the Azure Active Directory (Service Principal) from App Registrations.
- Go to Key Vault resource, Access Policy blade, assign read access to this Azure AD App (Service Principal) that we created in the above step.
- Set these 3 Environment variables
AZURE_CLIENT_ID
,AZURE_TENANT_ID
, andAZURE_CLIENT_SECRET
in your App Service. Get the values of these variables from the app that we created in step 1. - Use
DefaultAzureCredential
that we are already using now. This will automatically pick the credentials from the environment variables that we defined in App Service for the authentication.
Another way is to obtain Key Vault token dynamically and use that token to get the secrets from the Key Vault - https://docs.microsoft.com/en-us/samples/azure-samples/app-service-msi-keyvault-node/app-service-msi-keyvault-node/

Install LSM
You can use LSM like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
