Apache Portable Runtime (apr and apr-util), argon2, aspell, at-spi2-atk and at-spi2-core and accessibility.

Here's a demo simple cat command coded with Apache Portable Runtime:

#include <apr_general.h>
#include <apr_pools.h>
#include <apr_file_io.h>

int main(){
  //setup
  apr_initialize();
  apr_pool_t *mypool;
  apr_pool_create(&mypool, NULL);
  apr_file_t *file;
  char *myfile = "text.txt";

  //cat
  apr_file_open(&file, myfile, APR_READ, APR_OS_DEFAULT, mypool);
  apr_off_t offset = 0;
  apr_file_seek(file, APR_END, &offset);
  apr_size_t size = offset;
  char *mybuffer = apr_pcalloc(mypool, size +1);
  offset = 0;
  apr_file_seek(file, APR_SET, &offset);
  apr_file_read(file, mybuffer, &size);
  printf(mybuffer);

  //cleanup
  apr_file_close(file);
  apr_pool_destroy(mypool);
  apr_terminate();
  return 0;
}

To compile:

$ gcc -I/usr/include/apr-1 -lapr-1 -o mycat mycat.c

m4

The llc, lli, llvm-ar, llvm-as, llvm-bcanalyzer, llvm-c-test, llvm-config, and llvm-cov commands from the d software series of Slackware. Also, an off-script rogue demo of lcov.

There isn't much of a logical flow to these commands, but here are a bunch of examples to demonstrate syntax:

  
$ clang -E -emit-llvm hello.c > hello.i
$ clang -S -emit-llvm hello.i # outputs hello.ll
$ llvm-as hello.ll            # outputs hello.bc
$ llc hello.bc -o hello.s     # outputs assembly
$ llvm-as hello.bc -o hello.s # outputs assembly
$ llvm-ar r hello.a hello.bc  # outputs hello.a
  

For llvm-gcov:

  
$ clang -fprofile-arcs -ftest-coverage hello.c
$ ./hello
$ llvm-gcov show hello.c
$ lcov --capture --initial --directory . -o hello.info
$ genhtml hello.info --output-directory html
$ firefox ./html/index.html

$ #Create a manifest file
$ mkdir META-INF
$ echo "Main-Class: Main" > META-INF/MANIFEST.MF 

$ #Compile Java into bytecode
$ #This creates a file called Main.class
$ gcj -C hello.java
$ file Main.class

Here's an Ada dice roller. First, create a file called random_number.adb. This is the random generator function, and it accepts the integer I as input, and returns an integer X as output:

with Ada.Numerics.Discrete_Random;

function Random_Number (I : Integer) return Integer is
  subtype Random_Range is Integer range 1 .. I;

  package R is new Ada.Numerics.Discrete_Random (Random_Range);
  use R;

   G : Generator;
   X : Random_Range;

begin
   Reset (G);
   X := Random (G);
   return X;
end Random_Number;

Create a second file in the same directory called main.adb. This is the front-end part of the application. It accepts a number in the form of -d 20 or -d 6 from the user at launch. It sends that number to the random generator function, gets a random number up to the number, and printts the result.

with GNAT.Command_Line; use GNAT.Command_Line;
with Ada.Text_IO; use Ada.Text_IO;
with Random_Number;

procedure Main is
   ROLL: Integer;
   
begin
  loop
    case Getopt ("d:") is
       when 'd' =>
          -- random number
          ROLL := Random_Number(Integer'Value(Parameter));
          
          Put_Line ("You roll: " & Integer'Image(ROLL));
      when others =>
        exit;
    end case;
  end loop;

end Main;

Compile, and then run.

$ gnatmake main.adb
$ ./main -d 20
18
$ ./main -d 6

addr2line, ar, as, ld from the binutils package. Here is an example of the code and commands used for the as and ld example:

$ cat << EOF >> hello.c
> #include 
> int main(void)
> { printf("hello world\n");
>   return 0; }
$ cpp hello.c > hello.i
$ gcc -S hello.i 
$ as -o hello.o hello.s 
$ ld -static -o hello \
-L/usr/lib64/gcc/x86_64-slackware-linux/5.5.0/ \
/usr/lib64/crt1.o /usr/lib64/crti.o hello.o \
/usr/lib64/crtn.o  --start-group -lc -lgcc \
-lgcc_eh --end-group
$ ./hello
hello world
$

The library paths are specific to Slackware, but are similar on other distributions.

Here are some additional shownotes by @linuxoid@mastodon.ml:

The detailed process of transforming C source code to a binary execution module for your operating system consists of 4 step (utilities) and 5 files on disk:

1. hello.c - C source with macros
2. hello.i - text file with expanded macros but still C code.
3. hello.s - a text file in Assembly language.
4. hello.o - binary object code with instructions to the processor, but offsets there are not tied to memory areas relative to other object files and libraries.
5. hello - a binary executable file, with all object objects inside (maybe static libraries), ready for execution with the loading of linked dynamic libraries (*.so files in your OS distribution).

The 4 steps of compiling are:

1. *.c -> (preprocessing: cpp)-> *.i
2. *.i-> (translating: gcc)-> *.s
3. *.s-> (assembing: as)-> *.o
4. *.o-> (linking: ld)-> module_to_run

Pdfmom overview

gdiffmk for producing diffs of groff files.

glilypond for integrating lilypond musical notation into grof files:

    $ glilypond --pdf2eps -t ./b -- example.1 > example.ps.1
    $ groff -p -Tps example.ps.1 > out.ps
    $ okular out.ps

The grap2graph command to convert grap graphs to a bitmap. This requires the grap command, which does not ship with Slackware.

    $ cat internet.d | grap2graph -format jpg -density 300 > my.jpg

The grn command is a preprocessor for Gremlin files. It appears to be non-functional, but it's possible that an additional back-end is required.

The grodvi command converts Groff to DVI for TeX. It's basically a shortcut for

groff -Tdvi

Have your computer guess what groff command you need with grog

    $ grog blah.1
    groff -man blah.1
    $ grog -Thtml blah.1
    groff -Thtml -man blah.1

The philosophy and culture of bug reporting:

1. A bug is any unexpected interaction between you and a product.
2. A bug report offers you an opportunity to troubleshoot a problem. Ideally, it results in a solution before even being filed. Otherwise, it is a recipe for the developer to experience the same problem as you have.
3. Bug reporting is collaboration. When you file a bug, you are not disturbing the developers, nor are you exposing them as poor or nefarious programmers. You are developing along with them in an attempt to optimize an application you love.
4. A good bug reporting tool is also a task management tool.

Markdown opinion by mdoc programmer Ingo Schwarze

Geek social fallacies

The ending of the a2ps package, including psdiff, psbook, psmandup, psresize, psselect, and texi2dvi4a2ps. The greatest mystery is the showchar command, which appears to do nothing.

Upon further investigation (after recording), it seems that a2ps as distributed by Slackware also contains a collection of scripts called psutils, which provides fix*, ps*, eps*, *res, and showchar scripts.

The psutils collection is not yet in Slackware-current, so it is possible that it has been dropped from distribution. In the latest psutils sources, showchar appears to have been removed.

Here's the ipc* (from util-linux) demo in this week's episode.

Create a message queue with ipcmk:

$ ipcmk --queue
Message queue id: 294914

View available queues:

$ ipcs | head
$ ipcs | head
key        msqid  [...] used-bytes   messages    
0x98544aba 294914       0              0
[...]

  

Write an application to send messages:

#include <sys/ipc.h>
#include <sys/msg.h>
#include <stdio.h>
#include <string.h>

struct msgbuffer {
  long tag;
  char txt[128];
} message;

int main() { 
    int msqid = 294914;
    message.tag = 42;
    strcpy(message.txt,"hello world");
    msgsnd(msqid, &message, sizeof(message), 0);
    printf("Message: %s\n",message.txt);
    printf("Queue: %d\n",msqid);
    return 0; }
  

Compile it and run it:

$ gcc msgput.c -o msgput
$ ./msgput
Message: hello world
Queue: 294914
$ ipcs | head
key        msqid  [...] used-bytes   messages    
0x98544aba 294914       136            1
[...]
  

Compose an application to retrieve messages:

#include <sys/ipc.h>
#include <sys/msg.h>
#include <stdio.h>

struct msgbuffer { 
    long tag;
    char txt[128]; 
} message; 

int main() { 
    int msqid = 294914;
    msgrcv(msqid, &message, sizeof(message),42,0);
    printf("\nQueue: %d\n",msqid);
    printf("You got mail: %s\n", message.txt);
    msgctl(msqid,IPC_RMID,NULL);
    return 0;
} 

Compile and run:

  
$ gcc msgcheck.c -o msgcheck
$ ./msgcheck
hello world
$ ipcs | head
key        msqid  [...] used-bytes   messages    
0x98544aba 294914       0             0

The Linux Boot Process series by Dann (on Hacker Public Radio)

Listener feedbacks from Mastodon, including commentary about the Julian calendar, Flatpak sandboxing problems, Flatpak usability problems, clarification on Bzip2 and LZMA and ZIP compression.

The overview of util-linux continues with mkswap, which designates a partition of a special hard drive or a special file as "swap" space. NEVER run mkswap on a partition or file that contains data you care about.

$ sudo mkswap /dev/sdx1

The pivot_root command mounts a new location as your root whilst simultaneously unmounting the old one. You probably won't ever use pivot_root manually yourself. Its typical use case is during system startup, when an initrd is used to bootstrap an environment but then needs to be shunted away when the real root partition becomes available.

You can test pivot_root in a virtual machine, just as a proof of concept, as described in this episode, but if you have ever used chroot, then you have

The raw command talks directly to block devices, useful for fancy databases or other high-performance things that don't need a filesystem because they use their own optimized system for managing data. On some systems (like Slackware), you may need to do modprobe raw before using raw.

NEVER run raw against a block device with data (that you care about) on it. Here is a really simple proof of concept demo exercise:

# raw /dev/raw/raw1 /dev/sdx
# echo "gnu world order" > /dev/sdx
# dd if=/dev/raw/raw1 count=1
gnu world order
[...]

The setserial command sets and reports serial ports on a Linux system. On Slackware, you can see the script that generates serial port definitions in /etc/rc.d/rc.serial, with its associated config file being /etc/serial.conf On a distro using systemd, there is a unit file that creates serial ports. Serial ports are usually accessible to the group dialout, so if you are having trouble talking to a device over a serial port, be sure to add yourself to the dialout group, and then log out and log back in. Permissions for devices that communicate over a serial port (like an Arduino) can be managed manually (chmod 660 /dev/ACM0, for instance) or you can script udev to set permissions upon connection.

In the original release, there was a mixing error at the start. This has been fixed, and the SHA256 sums have been updated below.
