My first computer was a Radio Shack Color Computer 3 - 6809-based, running OS-9 Level II. It could run 32 processes at once, due to bank-switching a whole 1 Meg of memory.

After that, I got an AT&T 3b2, also known as a Convergent Safari. This was a Motorola 68010-based desktop.

Then, I graduated to a NeXT black&white "slab". I bought a used SPARCStation IPC in 1995, and put NetBSD 0.9 on it. I ran NetBSD on the IPC and a SPARCStation 10 until 2002.

I've been using Linux since 1997, starting with a DEC Alpha-based UDB, and downgrading to a x86 PC in 2002.

I run Arch linux, on my server and my laptop.

comment Opening a TCP port in Linux
Your example server code works better with Python 2.7 than it does with Python 3. You should probably say what version of Python you use.

comment Does the inode change when renaming or moving a file?
How about a comment about why you downvoted it? Is the above counter-factual, or irrelevant, or are you just a big fan of NTFS and VFAT?

comment Solaris 10 system - used disc space keeps on increasing even after deleting the directory
@lugiegu has remembered something I forgot. fuser is a Solaris program that does different stuff than lsof. Give it a try.

comment What is the reason for having numbers within the brackets of a function ?
I agree with Al Hazred here. The question is, in fact, different, due only to the variant interpretations of exec(2).

comment How to toggle between vim buffer and command terminal in vim?
@Adrian - I don't understand what you mean by "Console" in that case. You'll have to use more standard terminology, as what you asked just plain doesn't make sense. "Console" has a somewhat specific meaning in the context of X11 interfaces, but as far as I know, "Console" doesn't mean anything specific with respect to vim.

comment How to protect against data leak?
@Gilles - I'm afraid that in the USA, which is what roaima asked about, "intellectual property" is not a legal term. Lawyers may informally conflate patents, trade marks, patents and trade secrets into "intellectual property", but it doesn't mean much legally. Lawyers may claim that copying an idea is theft, too, but that doesn't make it theft. There are specific court cases in US law that say otherwise: en.wikipedia.org/wiki/Dowling_v._United_States_%281985%29

comment How to protect against data leak?
@roaima - No, I do not. There's copyright infringement, patent infringement and something related to trade secrets. None of these are theft, in a legal or ethical sense. And the phrase "Intellectual Property" is itself misleading, as none of copyright, patent, trade secret, trade mark or trade dress are "property" in any sense of the word "property" except the most sloppy and childish usage.

comment How to protect against data leak?
You are aware that this situation really isn't "theft"? Since you and your boss aren't deprived of the use of the copied file, nothing has been "stolen". So, this reduces to the unwanted copying problem that the RIAA and MPAA have been trying to solve for years, unsuccessfully.

comment Quick boot for desktop Linux?
I have no experience with Linux Mint, but the start-stuff-at-boot system makes a difference. I went from Slackware 12 to Arch linux (pre-systemd), and saw a huge speedup in boot on my laptop. Slackware uses an old school BSD scripted startup, don't remember what Arch used to use. When Arch moved to systemd, my laptop got another speedup in boot time. So: check to see what Linux Mint uses to start things up at boot time. It can make a difference.

comment Do I have a dead NIC?
@unkle_junky - I'd say you might have a dead NIC. If it's a PCI or PCIe card, re-seat it after cleaning contacts. Try a different cable - they go bad randomly. Try a different port on the router. If all that fails, you've got a dead NIC.

comment Do I have a dead NIC?
Consider running mii-tool and ethtool on the interfaces to see what they say. Don't ignore anything that they say that doesn't make sense: see if you can reconcile the apparent nonsense with reality.

comment What is an inode?
@DBS - interesting thought, dragging Russel's Paradox into Unix filesystems. Alas, "everything is a file" only went so far, rather like sets in NBG set theory giving way to classes at some point, and then, only in user land. In the kernel, not everything is a file.

comment What is an inode?
@DBS - If you're clever and careful, you could probably open the "raw device", /dev/sda1 or whatever, find the on-disk data, and modify it without touching the file's actual data. Other than that, the chmod command changes inode without accessing file data.

comment Why did “argument can be squisehd against option” prevail over “argument is always separate”?
Argument squishing was prevalent before POSIX. In fact, AT&T's Unix Labs had proposed a flag and option syntax that getopt() had pretty faithfully implemented by 1988. I can't really cite any docs, but that's when I got my first real Unix(tm) machine, and there was a manual section on the subject.

comment Terminal with image support
You can see a windowing system with in-band signalling in the "MGR" windowing system: en.wikipedia.org/wiki/ManaGeR . This worked as late as 1994 on a Sun SPARCStation-10 As far as a terminal running programs, that what the basis of Sun Micrososystem's NeWS system: en.wikipedia.org/wiki/NeWS As many have noted, everything has been thought of once, the problem is to think of it again.

comment keep getting broken pipe when ssh
This smells like it might be network problems, like maybe an unreliable NAT on a router or something. Can you detail the network setup between the two machines?

comment Characters visible in vi, but not in cat.
@sree - cat just writes bytes (not characters!) to stdout. The way you invoked cat, stdout was the TTY of the terminal emulator. That TTY or the terminal emulator chose not to show the ASCII-Nul bytes and confused you.

comment Apache httpd cannot parse php on CentOS 7
Shadin - you need to figure out why apachectl configtest says you've got php5_module loading twice. Find that out, and you've got a big hint about the error_log message.

They may not be required for PCI DSS compliance now - I saw them in a preliminary version in 2006. I haven't had a reason to read something that boring in a while.

comment unix system with malware
I'll confirm the last paragraph: Linux anti-virus only runs where corporate policy is rigid and stupid enough to require it. At least early revs of what became the PCI DSS had level 1 merchants running anti-virus on all servers, no exceptions, so such policies do exist.
