I am using hyperledger fabric 2.2 on the intel chip Mac Pro right now.
However, I am look forward to buy a new Macbook Pro with m1 chip soon in the future.
I have searched lot of communities and official website to check the hyperledger fabric support m1 chip Macbook Pro.
Anyone know does the m1 work with hyperledger fabric? and
if you it does not support, do you know why not?
Please let know any small information about the concern.
Thank you.
https://jira.hyperledger.org/browse/FAB-18389?jql=text%20~%20%22m1%22
this is what I officially checked that m1 is not supportive.
Hyperledger Fabric does not currently support ARM architecture, however as M1 MacBooks includes Rosetta2 you can continue to use the amd64 architecture images and binaries. See
https://github.com/hyperledger/fabric/issues/2994
for some details

I have a question that I need to implement blockchain for tamper proof record so what laptop specifications would be required to implement blockchain?
If u can run python or js u can make it so some dual-core laptop and u can also work on Linux without a GUI so old Pentium 3 will also work :D
on Azure there are Virtual Machines pre-configured for Data Science activities. There are images on Windows and on Linux - CentOS and Ubuntu. My question is - are there any important differences between image on CentOS vs image on Ubuntu? Of course - despite the OS itself ;)
From what I can see in specifications, there are mostly the same, but maybe there are some bits and pieces that have an important impact on using one of them.
The theory behind DSVM is that there is a build with all of the tools and drivers you need (to run on Azure Nvidia instances)that will work regardless of OS. So the difference is purely an OS one, simply because some organisations have infrastructure geared towards Ubuntu, others towards Redhat/Centos (and some even do Windows!)
The DSVM is an image concept that starts above the OS, so even the Windows editions will have basically the same toolset. if you look here there is a rundown of what the goals of DSVM are.
We will start using Microsoft Intune for all our devices soon, and while configuring Intune, the question came up of which certificate to choose, for authentication etc.
I have followed this link and others similar: https://learn.microsoft.com/en-us/intune/certificates-configure
However these links only explain how to install CA's, configure settings etc. I can not find a clear differentiation between the 2 certificates (SCEP and PFX) and why one would choose one over the other.
Are there any general guidelines to follow?
Edit: Our devices are mostly company laptops, with Windows 10.
It's hard to say how to choose one kind rather than the other one. It really depends on what devices you're using and what platforms runs for those devices:
You can create and assign a PKCS or SCEP certificate profile for
devices running the following platforms:
iOS 8.0 and later
Android 4.0 and later
Android for Work Windows 10
(desktop and mobile) and later
You can only use a SCEP certificate
profile for devices running the following platforms:
macOS 10.9 and later
Windows Phone 8.1 and later
So, it's clear that If your devices are using macOS 10.9 and later
,Windows Phone 8.1 and later platforms, you must choose to use SCEP certificates.
Also, it sometimes depends on what CA that your Network devices support. E.g, if your VPN devices only supports SCEP CA,you just need to use SCEP CA.
You can also refer to this Tech Note of Cisco to find more details about SCEP and PKCS.
For same devices:
If you are building a prototype or a small not critical service then go with PKCS12.
If you use SCEP profiles, you need to configure a Network Device Enrollment Service (NDES) server. So,If you are building a serious product (production and touching devices of people with sensitive info) then go with SCEP (you can get a free SCEP servers. It's not that complex).
Hope this helps!
I'm trying to develop for HoloLens but my laptop doesn't support the needed specs, so I was trying to figure out a virtualized solution (namely, using an Azure VM).
After unsuccessfully running the emulator on the Azure VM, I found that according to Microsoft (https://technet.microsoft.com/en-gb/library/hh831531), "The Hyper-V role is not supported on a Microsoft Azure virtual machine", which kills that idea.
Does anyone know of an alternative virtual option for developing and running the HoloLens emulator, which doesn't rely on the host machine's (i.e. my laptop) specs?
Yes, in the latest version of Unity which is Unity 5.5, there's a new feature called "Holographic Emulation" that will enable you to run on a simulated device directly in the editor.
As for the requirements, you need to have
Unity 5.5 installed in your machine
Windows 10 Anniversary Update (or later) installed
Here's the link to the blog in case you want to check more details about the simulator
Hololens emulator IS the Hyper-V virtual machine with Windows 10 and 3D graphic capabilities. The host machine should be able to run Hyper-V (CPU/BIOS limitation) and have a 3D adapter. More details are here:
https://learn.microsoft.com/en-us/windows/mixed-reality/using-the-hololens-emulator
Then you could install the emulator from
https://learn.microsoft.com/en-us/windows/mixed-reality/install-the-tools
Hololens emulator is not supported in VM due to CPU limitation, you can use holographic simulation in Unity instead.
I have a device that has an ARM processor and runs Win CE OS.
Now I have got a requirement to implement a node js server inside the device.
The same requirement was implemented on another ARM device that was running Linux
Since node is compiled for Linux they were able to run a node js server inside the device.
But there is no Win CE compatible version of node available
Is that not done yet or am i missing something?
I read about Microsoft chakracore, but I didnot understand much.
Does anybody know how to run node on Win CE running devices.
Any kind of leads/help is appreciated. Thanks
Windows CE provides an implementation of the Win32 API that is someway compatible with the full-Win32 version implemented on Windows desktop operating systems.
It also provides C/C++ libraries but, as you know, evil is in the details and those implementations can be considered a subset of those you have on the desktop and missing a single function or feature can force you to re-implement a huge amount of code to work around the limitation.
Windows CE is also meant to run on resource-limited devices with a limited amount of RAM and processing power and, honestly, node.js does not seem to exactly target this kind of platforms.
First I would like to understand if the requirement makes sense and why there is a need to mix a small real-time OS like CE with a huge interpreted and resource-hungry monster like nodejs.
windows CE has not been updated in over 3 years it is unreasonable to expect node.js to work as is on top of CE. windows on arm however (used by windows phone, windows Iot, and the ill fated surface RT) can run this https://github.com/nodejs/node-chakracore. Windows on arm only accepts thumb2 instructions, so you won't be able to use regular node.js.
This is b\c v8 just in time compiler does not produce thumb2 instructions. more reading material here: https://blogs.msdn.microsoft.com/ntdebugging/2014/05/15/understanding-arm-assembly-part-2/
