Depends upon how you are doing the tarpitting. Back when I did this (15 years ago) I used a program that created a raw socket to handle all TCP traffic that just responded with 0-byte sized windows to all TCP packets (so overhead was min

About 15 years ago, I ran a tarpit at my then current job (small ISP for commercial clients and web hosting) that tarpitted all TCP traffic on unused IP blocks. It did slow down network scans and had I gotten around to it, I could have pro

Yes, depending on how basic, or how long you want to work on it. Gary Kildall did CP-M. Tim Patterson did 86-DOS (later bought by Microsoft and turned into MS-DOS). Terry Davis did TempleOS. And I'm sure there have been other, one-

It depends upon the assembly language. Intel defines its opcodes as `dest,src` and Motorola did `src,dest`.

But doesn't Python also support modules written in C? Does Python get a pass for that? Or is it because the standard Python library is so large that it's not needed as often?

I use it at work to process SIP messages on behalf of a cellular carrier. The actual parser is written using LPEG, a parser expression grammar for Lua. Because Lua is meant to be embedded, it only has the functionality required to do the

As the one who wrote the C version (which I haven't had a need to use once I wrote it), why can't it be used? Not allowed to use modules written in C? Or lack a C compiler? Also, please define "common operations" for m

I came across a reference to such a language in the January 1986 issue of "Computer Language" (I have the magazine right in front of me as I type) and the idea has remained firmly lodged in my brain ever since. Some examples:

I had the opposite experience. All I needed was a way to do a simple GET. That's it (and that's all it still is, by the way). Instead of spending half an hour writing the code, I decided to use libcurl---that's what it&#x2

And the Intel x86 line still has ENTER and LEAVE, which do similar things to the 68000 LINK and UNLINK instructions.

Does any company make $500,000,000 a year?

by spc476 6y ago
Some math shows that can't work. Half a trillion to 35 million is US$15,000 per person. For one year. And people will complain that US$15,000 is not enough to live on. What happens in year two?

For issue #3, it would have been nice had the TTY layer sent DLE ESC when someone hits the ESC key. As it is now, once you read the ESC key, you have to wait some number of milliseconds to see if more data is coming in, and if not, then ju

I hate to say it, but the standard for C1 escape codes, ECMA-48, does list "\e[21m" as "double underline". I can see where one might think it does a "bold off" but alas, that isn't in the standard. Th

Don't tell my coworkers this---we use Lua to process SIP messages for the Oligarchist Cell Phone Company. I found LPEG to be way nicer than Lua's patterns (or even regex) for parsing, and there are other networking modules beside

When I participated in NaNoGenMo 2015 [1], I ended up having to emulate a very small subset of MS-DOS [2]. That meant loading in an MS-DOS `.EXE` file into memory and running it. I had a 32-bit Linux system, so I was able to use the `vm86

xelxebar was asking about this historical background of the x86 architecture, not a historical background of Linux. Knowing how the x86 architecture evolved over time helps explain the oddities.

Generally speaking, the LEA instruction will never modify the flags, while ADD and SHL will.

See if you can find any books about assembly language programming for the 8086 (or 8088) and the 80286. Just those two should give enough context for why things are the way they are on the x86 line.

The same is true in C++ and Java, only the "self" argument is completely hidden in that case.

Structs are a natural way to organize data, but that doesn't necessarily make it "OO". In Lua, a module is typically a table (associative array really) of functions. All of the standard modules that come with Lua are just c
