The real problem was the core concept of isolating knowledge, i.e. Layer 2 doesn't know anything about layer 3. That's a flawed concept. The trivial, yet essential protocol ARP break the OSI model, for example. And then there&#x27

There is a SDR device for hacking that is self-contained. It's the HackRF+Portapack, ( https://hackerwarehouse.com/product/hackrf-one-kit/ ) - which costs significantly more. It uses a FPGA to decode raw signal

I wrote this because there are several advantages to using make when writing shell scripts, such as improved documentation, working in teams, etc.

As I recall, the Sun keyboards (and OS) had many other features and advantages that I miss. While many keyboard of the time was limited to two "Meta-" keys (Control- and Shift-) the Sun keyboard had 5 meta-keys, so you can type A,

I ran it on a Mac IIcx. As I recall, one could also purchase Sun's NeWS windowing system for it.

Years ago, or perhaps decades ago, when there switching languages every few months wasn't common, yes - syntax was not only memorized, it was second nature. Not only that, but the language influenced how you thought and solved computin

I spent 2 years using a semantic reasoner to develop an ontology for reasoning about smartgrid vulnerabilities. Ignoring the web aspect, ontologies are very hard. In addition, one needs to use multiple languages like one to express the onto

And how do matching test vectors ensure there are no timing attacks? Or memory leaks that disclose private keys?

I've used it when I was doing a pentest - searching a network for leaks of information. I wrote dozens of shell scripts that scanned the network for .html files, then extracted URL's from them, downloaded all of the files referen

One has to wonder about a technical blog that starts off with "Using the orginal RTL and pair that with HDSDR software on linux". So I did a search, and HDSDR only runs on Windows.

This is why the DEL key is all ones. It was used to overpunch the wrong letter on a paper tape and replace it with a character that meant ignore (delete) it. As done on an ASR-33 https://en.wikipedia.org/wiki/Teletype_M

Incorrect. It was the first case of a software bug being an actual bug. In other words - a true pun. The first computer bug was found in 1843 by Ada Lovelace. https://en.wikipedia.org/wiki/Software_bug#History Thomas E

You were the one who said RPC should be used instead of SSH. People use SSH because it's secure, despite the issues in passing parameters. Suggesting that RPC be used instead of SSH while ignoring security is terrible advice.

Yes there is. You want the filesystem to be flexible. If the shell doesn't like those characters, use a different shell that doesn't care. It's brain-dead to create a filesystem that prevents flexibility in user interfaces.

It's a bash programmer issue, not a bash issue. If you want spaces to be unparsed in parameters, you "quote" the parameter. A="spaces in the argument" touch "$A" ls -l total 0 -rw-rw-r-- 1 m

You can include quotes in arguments on Unix systems. The only tricky bit is getting meta-characters past the shell to the command the shell executes. Example #!/bin/bash Q1="'" Q2='"' echo &

You can use stdin: echo *.txt | read_stdin_and_get_filenames You can use environment variables: export SPOOLDIR=$HOME/myspooldir; empty_spool_directory You can use a single argument: echo *.txt >list_of

I think this indicates a huge difference between Microsoft/UNIX mindsets. Microsoft allowed rename *.txt *.bak To do this, the "rename" command had to understand how to parse the asterisk character while being familia

Yes, that is true but very misleading. If the single instance does not create any new processes, then there is no practical difference. The difference occurs when a process A created process B and process B spawns one or more processes.

The POSIX shell has nothing to do with the syntax of the command. You can write a shell script that can parses cp from=foo to=bar if you wanted to. The shell expands metacharacters and variables, and sets up STDIN/STDOUT. But = is

In the Unix world, environment variables are passed to ALL processes spawned by the parent, including sub-processes. For example, if you log onto a computer, and your HOME variable is set, then every single process you launch will know your

Oh. I was confused until I realized the publishing site was Microsoft. Apparently "Everyone" only refers to Windows programmers, and Unix/Mac/whatever programmers do not exist in this universe.

I think it's more likely the reaction to someone who uses magic languages that perform complicated actions over a simple assignment. If you think of C as a high-level assembly language whose assignment instruction is converted into a s
