Setting environment variables of mkl - sh
In order to set the environment variables of the mkl toolset on linux, I have to execute the script mklvars.sh. But now I get the errors
/opt/intel/mkl/bin/mklvars.sh: 33: /opt/intel/mkl/bin/mklvars.sh: typeset: not found

The error lines start with
typeset SCRIPT_NAME=$0
typeset MOD_NAME=mod
typeset MKL_LP64_ILP64=
typeset MKL_MOD=
typeset MKL_TARGET_ARCH=
typeset MKLVARS_VERBOSE=

typeset MKL_BAD_SWITCH=
typeset OLD_LD_LIBRARY_PATH=
typeset OLD_LIBRARY_PATH=
typeset OLD_MIC_LD_LIBRARY_PATH=
typeset OLD_NLSPATH=
How can I fix that, and what exactly is the problem?
Try this
source /opt/intel/<address>/mklvars.sh
For example, I remember I did,
source /opt/intel/mkl/bin/mklvars.sh intel64
You need to source the environment variables. This should solve your problem. Hope it works !

How to use bpf_probe_read() to copy large length data in EBPF program?
I am trying to dump the contents of the user space buffer in write() system call by running ebpf programs on tracepoint/syscalls/sys_enter_write.
I want to copy data with a maximum length of 1024, so I use BPF_MAP_TYPE_PERCPU_ARRAY to temporarily store the expected data structure, but when reading data through bpf_probe_read, I get an error from the verifier: load program: permission denied: 11: (63) *(u32 *) (r2 +0) = r1: R2 invalid mem access 'inv' (21 line(s) omitted).

i'm really confused, hope someone can help out, Thanks!
TL;DR. You want to pass a pointer to bpf_perf_event_output, not a pointer to a pointer. Verifier Error Explanation 41: R0_w=inv(id=0,umin_value=16,umax_value=1039,var_off=(0x0; 0x7ff)) R1_w=ctx(id=0,off=0,imm=0) R2_w=map_ptr(id=0,off=0,ks=4,vs=4,imm=0) R3_w=inv4294967295 R4_w=fp-24 R5_w=inv(id=0,umin_value=16,umax_value=1039,var_off=(0x0; 0x7ff)) R6=ctx(id=0,off=0,imm=0) R7=inv(id=0,umax_value=1023,var_off=(0x0; 0x3ff)) R10=fp0 fp-8=mmmm???? fp-16=mmmmmmmm fp-24=map_value 41: (85) call bpf_perf_event_output#25 invalid stack type R4 off=-24 access_size=1039 Here the verifier complains that the fourth argument to bpf_perf_event_output is pointing to the stack with an access size that is way beyond the actual stack size. The fourth argument is &event. Root Cause The fourth argument to bpf_perf_event_output should be a pointer to the data to post on the ring buffer. Hence, you want to pass event as the argument, not &event.
Convert subnet mask to cidr notation (Scala)
Here's what I have so far:
//converts IP to a decimal or decimal to IP (working)
private def longToIPv4(ip:Long): String = (for(a<-3 to 0 by -1) yield ((ip>>(a*8))&0xff).toString).mkString(".")
private def IPv4ToLong(ip: String): Long = ip.split("\\.").reverse.zipWithIndex.map(a => a._1.toInt * math.pow(256, a._2).toLong).sum
//convert subnet to cidr (to do)
if(ip.matches("""(\d{1,3})\.(\d{1,3})\.(\d{1,3})\.(\d{1,3})\/(\d{1,3})\.(\d{1,3})\.(\d{1,3})\.(\d{1,3})""")){
val pattern = """(\d{1,3})\.(\d{1,3})\.(\d{1,3})\.(\d{1,3})\/(\d{1,3})\.(\d{1,3})\.(\d{1,3})\.(\d{1,3})""".r
val pattern(o1, o2, o3, o4, o5, o6, o7, o8) = ip
}
I'm able to parse the subnet into octets and convert IP to decimal and vice versa, now I just need to convert subnet to cidr notation.
According to your example in the comment, I assumed that the conversions is as elaborated here. I wouldn't do it with regex. You can try something like:
def cidrToSubnet(cidr: Int): String = {
require(cidr > 0, "CIDR is out of range! It must be between 1 (inclusive) to 32 (inclusive).")
require(cidr < 33, "CIDR is out of range! It must be between 1 (inclusive) to 32 (inclusive).")
val ipInInt = if (cidr == 32) (Int.MaxValue << 1) + 1 else Integer.MAX_VALUE << (32 - cidr)
ipInInt
.toBinaryString
.grouped(8)
.map(bitString => Integer.parseInt(bitString, 2))
.mkString(".")
}
def subnetToCidr(subnet: String): Int = {
32 - subnet.split('.')
.map(Integer.parseInt)
.reverse
.zipWithIndex
.map {
case (value, index) =>
value << index * 8
}
.sum
.toBinaryString
.count(_ == '0')
}
Then running:
1.to(32).foreach(i => {
println(i + ": cidrToSubnet(i): " + cidrToSubnet(i) + " subnetToCidr(cidrToSubnet(i): " + subnetToCidr(cidrToSubnet(i)))
})
outputs:

To me it looks like you want to convert something like 1.2.3.0/255.255.255.0 to 1.2.3.0/24
With the The IPAddress Java library, it is trivial because it parses address/mask notation and can print addresses in many formats, the default format being CIDR notation. Disclaimer: I am the project manager.
import inet.ipaddr.IPAddressString
def convert(arg: String) {
val ipaddStr = new IPAddressString(arg)
println(ipaddStr.getAddress)
}
convert("1.2.3.0/255.255.255.0")
Output:
1.2.3.0/24
Laravel 5.1 index.php throwing reflection error and could not locate the controller
I am trying to setup my laravel 5.1 project in one of our testing server (LAMP - debian linux, apache 2.4). Copied the entire laravel project from dev machine to testing machine. Did the necessary configuration. We have created a custom controller named loginController. When i try to reach out http://192.168.0.1/index.php i am getting the below error.
My controller looks like -
namespace App\myfolder\Controllers;
use App\Http\Controllers\Controller;
use App\User;
use Validator;
use Illuminate\Foundation\Auth\ThrottlesLogins;
use Illuminate\Foundation\Auth\AuthenticatesAndRegistersUsers;
class LoginController extends Controller
{
use AuthenticatesAndRegistersUsers;
protected $username = 'username';
public function __construct()
{
require app_path() . '/common/constants.php';
}
public function index()
{
return view('myfolder/themes/' . SELECT_THEME . '/login');
}
}
Please someone help.

I solved the problem. Reason was that my controller name was LoginController.php but routes.php was searching for loginController.php. After changing the first letter to small case it started working.

If this happens consistently at roughly the same location in your code, then you seem to have found an internal error in the compiler, i think best way to proceed is to first submit this as a bugreport to apple ( the URL is listed in the output you pasted ). And then, if you would like to proceed, try to make changes to the code you are trying to compile, like comment out the first half, then retry, then comment out the second half, and retry. This should point to the code causing the internal compiler error. Sometimes reordering some code will solve the problem for you. So at least you can continue developing.
iPhone/Objective-C - Strange error when passing string to method
I am using http://www.sudzc.com/ to access SOAP Web Services in my iPhone application. I have a method in ASP.NET that takes a string and returns a string (facebook access token to be exact). This string is the following: iOCCeM4WGIwBlDxECRFr4AfIEsW598Z4sYjk2uMxsyo.eyJpdiI6IkZPQlN1YWlGNXY0aWs3SmFMWFUwcVEifQ.ITh3ZBGrbgU8DsYWz6d-S4Q1iNlQ8DwKGZB6RZvOkTUpa0VmW7qFS6MO1tkauHoJMFrOlwSrvVuMEO_SQTh8xtR2d0219PPSshiYBHYkjsokSYTuyIaSclVIrL2vh7xH Every now and then I get an error like the following in my application and I'm not quite sure why. The actual string is a nvarchar(255) field within my database. This error does not happen all the time. But it has happened quite a few times. Any help would be greatly appreciated as to how I can fix this issue. Thanks in advance.

Looks like my web service is down and I'm simply not handling it properly in Objective-C. Hence why it's returning HTML (ASP.NET error page) instead of the string.
