• NFS Server not responding when Mac is mounting

  I've setup a NFS Server on a Ubuntu 18.04 machine. The problem is when I mount it on a MacBook Pro, and move files from Mac's disk to the mounted foulder, the system freezes.

  Looking at the logs on the server site through vim /var/log/messages i see this error:Dun

  lockd: server MacBook-Pro.local not responding, timed out
  

  Here's my exports file:

  /storage/public *(rw,async,no_subtree_check,insecure)
  

  Does someone know what could it be?
• Getting absolute pathname of a file in c

  I'll describe the problem- I have a configuration file which has in its first line a path to a DIR- char students_Dest[LINE_LENGTH]; FILE *f_Conf = fdopen(fd_Conf, "r"); fgets(students_Dest, DIR_LENGTH, f_Conf); //Getting the dest of the students DIR

  So I wrote the line to the buffer

  Now, I opened the DIR with
  DIR *students_Dir = opendir(students_Dest);

  And in this directory there are more directories that each one of them has a main.out executable.

  So i Wrote this code

  struct dirent *dir_Entry;
  char real_Student_Path[128];
  while((dir_Entry = readdir(students_Dir)) != NULL){
                  if((strcmp(dir_Entry -> d_name , ".") == 0) || (strcmp(dir_Entry -> d_name, "..") == 0))
                          continue;
                  printf("%s\n", dir_Entry->d_name);
                  realpath(dir_Entry->d_name, real_Student_Path);
                  printf("%s\n", real_Student_Path);
  

  But when I print real_Student_Path I get the relative path + cwd of this prog, not students_Dest + dir_Entry String. I think that I didnt understand realpath, But I cant understand what exactly.

  Could anyone help me? Thank You!
• How can I max out the computers CPU?

  I feel like it should be possible to max out the CPU with a simple script from Chrome Dev Tools. However, I haven't managed to work out a method of doing it.

  Something like for(var i=0; i<999999999; i++) { Math.random(); } does use a bit of CPU for a couple of seconds, but doesn't get to max 100% utilization on all cores/threads.

  So what (preferably short and simple) Javascript code can I run in Chrome Dev Tools to accomplish this?
• Intel Atom CXXX family (Denverton) and max RAM

  I'm about to acquire a motherboard based on Intel Atom C3958 (SoC) for my home hi-end NAS/microserver.

  Motherboard will have 4 RAM slots for 2 channels. For my tasks I need minimum 256Gb of ECC RAM and at the first glance the CPU fulfills my needs. (spec is here, page 115: https://www.intel.com/content/www/us/en/products/docs/processors/atom/c-series/c3000-family-datasheet.html)

  Although the spec claims the CPU supports 256 gigs, there are few limitations:

  1. The ECC SDRAM device must be of the same type and width as the SDRAM devices used for the data bits. This limitation is driven by the DDR4 spec.
  2. It is NOT alright to use x16 SDRAM devices for data and a x8 device for ECC.
  3. It is NOT alright to use x8 SDRAM devices for data and a x4 device for ECC.
  4. Memory based on 16 Gb dual rank technology (including maximum memory configuration of 256GB) is supported by silicon but not validated on Intel platforms.

  Candidates:

  https://www.mindfactory.de/product_info.php/64GB-Samsung-RDIMM-DDR4-2933-regECC-DIMM-CL21-Single_1311574.html

  Could anyone, please, clarify this for me: will the mentioned modules work? Or may be someone has already built such a system.

  Thanks! Before asking tried to find something related, but without luck.

• .NET CORE getting universal password from Novell eDirectory in plain text in C#

  The question title is self explanatory. In Novell eDirectory there is a supported way of getting universal password in plain text programmatically. We tested this with C language and it works, but due to our project requirements we need to use .net or .net core for this. Nuget we are using for this project is this: link.

  To get this working Extended operations must be used, but I haven't been able to understand how to send extended request.

  My code for connecting is following:

  using (var cn = new LdapConnection())
  {
      cn.SecureSocketLayer = true;
      Console.WriteLine("Connecting to:" + ldapHost);
      cn.Connect(ldapHost, ldapPort);
      cn.Bind(loginDN, pwd);
      Console.WriteLine(" SSL Bind successfull");
  }
  

  LdapConnection has ExtendedOperation available and as I understand this is what we need to use for this request. Here I found some example of how to use it, but unfortunately for us nothing there really helped us to understand how to proceed.

  My question is: was someone able to get universal password from eDirectory and if so, then how?

• How to compress the image size using C# Dot Net Core

  I am using .NET Core 2.2 In my code, I am using IFormFile to upload images. How can I compress the image size (to KB) just before it is uploaded to the server ? I search for solutions but those answers were related to Bitmap but since I am using IFormFile therefore I want solution related to it.

  I will internally check the image size and if its size is upto 700KB, I don't want to compress. But if it is higher, then I want to compress and upload. Sample codes would be very useful

  I tried to use Magick.NET package. But the problem is, how can I make IFormFile to MagickImage type ?

  foreach(IFormFile photo in Images)  
  {
    using (MagickImage mi = photo)  // Cannot implicitly convert type 
                                    //Microsoft.AspNetCore.Http.IFormFile to ImageMagick.MagickImage
     {
        mi.Format = Image.Jpeg;
        mi.Resize(40, 40);
        mi.Quality = 10;
        mi.Write(imageFile);
     }
  }
  
• Having Angstrom build and Poky build in one repository

  I have successfully made a test image (core-image-minimal) for Colibri-imx6 board using the poky distribution. The kernel does not completely load when the image is deployed on the board. So, I have decided to make a test image using the Angstrom distribution under Yocto.

  The specifications are Ubuntu 18.04, Linux kernel-4.9, Bitbake 1.44, gcc 4.8.5, Python 2.7.15+, Yocto version Zeus, Poky version 3.0 and Target system is arm-poky-linux-gnueabi. Below is a screenshot of the subfolders in the project folder:

  

  I wish to have more than one build folder, one for poky distribution and one for angstrom distribution.

  The current error I am facing is the following after making the changes in local.conf in the new build_angstrom folder:

  What layers/changes will I have to add to make this possible? Do I have to clone Angstrom distribution and keep it separately? Thanks!

• Minimum FFMPEG configure options for H264 decoding

  I'm working on a project using an LS1021A board, which has a Cortex-A7, NEON, FPU, etc, which seems to be very similar to a Raspberry Pi 2. We are streaming in H264 via RTP (UDP) with VLC to simulate an IP Camera with the end goal of extracting the raw RGB frame data (in a C app) to be used elsewhere in the system.

  So, I'd like to compile ffmpeg and the associated libs to do only H264 decoding, using libavcodec in C code. This will be running on a custom linux OS with tight size constraints, so lib size needs to be as small as possible.

  I have the following so far after a day or so of googling:

  ./configure --disable-encoders --disable-decoders --enable-decoder=h264 --enable-small --enable-cross-compile --arch-arm --target-os=linux --cpu=cortex-a7 --disable-debug --cross-prefix=${GCC_PREFIX} --prefix=/c/Users/labuser/Desktop/build --extra-cflags='march=armv7-a -mtune=cortex-a7 -mfpu=neon-vfpv4 -mfloat-abi=hard' --enable-neon --disable-devices --disable-sdl --disable-ffprobe --disable-ffserver --disable-doc --disable-w32threads --disable-ffplay

  Since I'll be using libavcodec directly, I'm not sure if some of these --disable switches are needed, but can anyone give any pointers on if this looks acceptable or if there are any other switches I should be using?

  Thanks!
• Lubuntu 16: 'USER namespaces aren't enabled in the kernel' when deploying Lambda on AWS Greengrass

  I have a Raspberry Pi B running Lubunutu 16. I have installed AWS Greengrass on it and can see it is running fine.

  However when I go to deploy a Lambda, an error pops up & the deploy fails-

  Is there a way to enable user_namespaces on Ubuntu/Lubuntu?
