[Announcement] Evolution benchmark for Linux

Hi All,

We at Waverian decided to rewrite the ancient "Livermore Loops" for modern OSes, write both a CLI , a lib, and a GUI for it + publish the source code on Github (for the CLI). The new project is called "Evobench", because it does benchmark computers across different decades (modern vs 1990) and categories (Linux server vs an iPhone). Like a 486 vs a Pentium 1 vs a modern AMD Threadripper vs an iPhone. How crazy is that?

We need help packaging it and uploading into the Debian "main ...

Re: When Debian 11.4 ? Release schedule?

Canci: good question.
The reason is that debian security repository is really slow for me, (I'm from Ukraine, and it takes about 15 min to install security updates per server, speeds are very slow ) and I need to install a lot of new servers (30 or more). I do disable security repo, but enable Debian proposed updates. I always use latest debian stable. New point release just includes latest security updates and it's convenient to use.
The difference is that standard Debian mirror does exist in ...

Re: DHCP: What is the diff between "client" and "your" IP?

Both answers not very helpful.
And first search gives me exactly zero useful results. (Google is not _that_ good)

Anyway, "client IP" allows to query extra parameters about "your IP" from a different interface with a different IP, which I think is redundant. (since client can spoof IP).
But this thing is not very clear at first sight from an RFC. It took me several reads.

basically I think DHCP can work just as well without "client IP" field, getting away only with "your address" field.

DHCP: What is the diff between "client" and "your" IP?

Hi,

Looking at DHCP RFC2131 - What is the diff between "client" and "your" IP?

ciaddr 4 Client IP address; only filled in if client is in
BOUND, RENEW or REBINDING state and can respond
to ARP requests.
yiaddr 4 'your' (client) IP address.

I read it, but still don't understand.
In reality clients often fill both fields with same value.
But is there any distinction ?

Re: Introducing : Brand-new Internet Protocol "Five Fields"

50-bits can be put into 64-bit integer, so there is only 1 extra CPU operation - the bitmask (bit extract). It is way faster than trying to process 128-bits on 64-bit CPU (IPv6) or doing checksums + fragmentation on every hop (IPv4).

Considering the other optimizations (such as no ARP), in reality IPFF should be faster than IPv4 or IPv6.

Re: Do you think PCs will become obsolete in near future ?

I think not.

All the people I know, that are buying smartphones and tablets, are buying them *in addition* to their current PC (desktop or laptop). No one is buying a tablet to replace a PC.

Introducing : Brand-new Internet Protocol "Five Fields"

Hi all,

I have created a new Internet Protocol "Five Fields".

Why ?
Because IPv6 is hard to use, and I wanted to keep look & feel similar to IPv4. Problem with IPv6, is that those addresses are very hard for humans to remember, compare and visualize topologies in human brain.
IPv4 has great look & feel, but it is exhausted. So I wrote a new replacement for IP.

I did it, because I don't like to work with something long like this:
2001:db8:2e1:1a73:149f:88ff:fe81:6116

And it would be better ...

Re: How-to boot Debian into text-mode (80x25) ?

Okay, it seems few things combined helped:
1. GRUB: (in /etc/grub.d/10_linux...)
gfxmode $linux_gfx_mode
needs to be removed.
2. GRUB kernel: (in /etc/default/grub)
nomodeset
3. GRUB itself: (in /etc/default/grub)
GRUB_TERMINAL=console
GRUB_GFXMODE=640x480

Only those modes together helps !

For me this DOS-style is okay, no need to enlarge anything, as this is a 13" laptop. (back in the 90's I worked on a 14" CRT desktop monitor, so it's fairly close experience, except for wide-screen aspect ...

[SOLVED] How-to boot Debian into text-mode (80x25) ?

Problem: I can't see anything at the hi-res of modern monitors, as my eyes degrade.
I need to console lower res to good-old DOS-style, 80x25.

I installed brand-new Debian 8 (netinst), no X11, no display manager for now. (Intel 4400 graphics chip)

I tried: edit in file /etc/default/grub:
GRUB_TERMINAL=console
GRUB_GFXPAYLOAD_LINUX=text

# update-grub2

But it only affects first part of the boot.
Right before user login appears, Debian resets to hi-res.
How to force it into text mode?

Thanks ...

Chinese ARM PC for $90 - CubieTruck

It is a 3rd generation ARM-based SBC (single-board-computer) aka Liliputer :)

http://store.r0ck.me/blogs/news/9361679-cubietruck-is-ready-to-order-now
And
http://www.Cubietruck.com

based on AllWinner A20 CPU (ARM) + 2 GB RAM + VGA !
This model: VGA port can bring older monitors to life, and 2 GB of RAM can definitely change the desktop experience in a big way.
Should be good ! I hope it will run Debian-ARM with KDE and Android just fine.
Have ordered one to see how it goes.
