kandi X-RAY | addc Summary
This module implements an on-line (streaming) agglomerative clustering algorithm (AddC) for non-stationary data as described in Guedalia et al., with modifications as given in Zhang et al.. Further improvements include building the main AddC data-structure on top of the David Eppstein's dynamic closest-pair algorithm/data-structure (FastPair), and the ability to use a variety of different kernel functions. The AddC algorithm is simple and fast. The algorithm can be summarized in the following three steps: For each data point arriving;. The algorithm can be understood as follows: Three criteria are addressed at each time step, minimization of the within cluster variance, maximization of the distances between the centroids, and adaptation to temporal changes in the distribution of the data. In the first step the within-cluster variance is minimized by up-dating the representation in a manner similar to the well- known k-means algorithm. The second step maximizes the distances between the centroids by merging the two centroids with the minimum distance (not considering their weight). The merging is similar to most agglomerative methods. Finally non-stationarity in the data generating process is anticipated by treating each new point as an indication to a potential new cluster. There are other Python versions here and here that also look pretty cool.

QUESTION
I'm currently integrating a React component with Azure Media Player. I followed the documentation and first, I added the required CDN urls to the index.html file. Then I added the sample code into the App. The problem is, it throws the error 'amp' is not defined no-undef

In your CSS file, try adding height in div-style.
QUESTION
For development purposes, I am trying to setup:
- Azure Cloud: Virtual Machine with Windows Server 2019 acting as Domain Controller for Active Directory. machine also has DNS and DHCP.
- VPN Point-To-Site so that local (physical) workstations can connect to Domain Controller
- Join local (physical) workstations (Windows 10 Pro)to Active Directory domain.
Item 1 - done. I have up and running Windows Server 2019 with AD DC Item 2 - done. From local machine (Windows 10 Pro) I can ping AD DC. Item 2a - done. I have one Azure VM (Windows Server 2019) that can also ping AD DC. Item 3 - not working. Local machine (Win 10Pro) can't join AD domain (addc.local). Item 3a - working. Azure VM (WinSer 2019) join AD domain (addc.local).
I tried dozen of tutorials. Finally I (partially) succeeded with:
- Windows Server 2019 – Active Directory Installation Beginners Guide - Success
- How to install VPN on windows server 2019 - Fail. Can't establish VPN.
- Azure - VPN Point to Site | Step By Step Tutorial - Success
Finally I got it up and running with 1 and 3.
- Considering that Azure VM can join Active Directory, I think that AD DC is properly setup. Both machines belong to same VNET.
- Considering that local machine can ping AD DC seams that VNET is properly setup.
- What I don't get is why Azure VM can resolve and join 'addc.local' domain, while local machine can't. On both machines, in network adapters preferred DNS is same: IP address of Domain Controller.
First question is why this doesn't work for local? Second questions is this proper way to do it anyway (taking into account requirements)?
...ANSWER
Answered 2020-Nov-12 at 07:33In this case, you may check the followings:
- Usually the VPN client will inherit the DNS servers configured on the Azure VNet. If you have set the custom DNS server of the Azure VNet is the private IP address of the AD DC after you set up a client VPN connection. You could re-download your VPN client packages from the Azure portal. See this1 and this2 for more details.
- Can you
ping
ornslookup
the AD DC with its FQDN likedcVM.addc.local
? If not, it might be a DNS issue. Read https://docs.microsoft.com/en-us/azure/virtual-network/virtual-networks-name-resolution-for-vms-and-role-instances#name-resolution-that-uses-your-own-dns-server - For best performance, when you are using Azure VMs as DNS servers, IPv6 should be disabled.
- Not sure, but you could try this solution.

I have the following hex opcode sequence for a 8051 microcontroller
785679107A247BFD7C347D407E51745568F869F96AFA6BFB6CFC6DFD6EFE
I found this repo that converts hex to instruction sequences https://github.com/anarcheuz/8051-disassembler.
Using that I was able to get the following assembly instructions
...ANSWER
Answered 2020-Jun-05 at 15:56That looks like disassembly of the string of ASCII characters, not the binary values they represent! Notice that the middle column (the machine code) is all 0x30..46, i.e. ASCII codes for '0'
to 'F'
.
e.g. the first 2 bytes you disassembled are 37 38
, which are the ASCII codes for '7'
and '8'
, but what you want is a single 78
byte.
You need to hex un-dump into binary before feeding it to that disassembler.
