Name and Shame Spam Senders With OpenBSD

lukas.mach Re:the known bad addresses part seems dangerous (166 comments)

And you don't even have to have access to send mail from that server - you can just fake the headers, the server on the other side has no way of knowing.

Second Netbook Wave Begins

lukas.mach Re:A bit too heavy IMHO... (318 comments)

Go to a nearest shop and try to life the 9" eee and the 10" eee. It's a difference. I have a 1.45kg tablet and when it comes to its weight it's really only borderline usable. The 9" eee on the other hand has the perfect weight - light enough, yet not so light to be shaking when you're reading an e-book on bus.

Ubuntu's Laptop Killing Bug Fixed

lukas.mach Re:As per "Flamebait Story" (271 comments)

You're writing "Wrong", but what you say isn't really in conflict with what I wrote. Yes, it's easier for a given developer to fix a bug in Linux software or in kernel/driver. Yes it's easier for them to achieve the perfect state where everything works according to specification/protocol. But when the ethernet card decides for no particular reason to send 1101 instead of 1100 every once in a couple of kBs, it's going to be a bigger deal in a cleanly designed system than in a self-repairing pile of junk.

Given that these kind of bugs will be corrected only when the manufacturers will sell more than say 25% of it's hardware to Linux clients, I humbly predict that these bugs will be fixe in approximately infinity years.

Ubuntu's Laptop Killing Bug Fixed

lukas.mach Re:As per "Flamebait Story" (271 comments)

Hardware will always have bugs and they always will be hard to fix. It's the OSes that should step up and act more like error correcting codes. Windows already kinda work like that - by being a monstrous pile of ugly hacks, it naturally gained resistance from relying on something external actually working.

Ubuntu's Laptop Killing Bug Fixed

lukas.mach Re:Only Ubuntu? (271 comments)

> That's GNU/Linux.

Yeah, I'm sure that the GNU stuff around the kernel (like bash and Gnome) has really big influence on the settings energy saving levels of hardware.

Ubuntu Download Speeds Beat Windows XP's

lukas.mach Re:what about packet loss? (515 comments)

> echo 0 > /proc/sys/net/ipv4/rfc{11,25}49

What should that do? It seems I can't create a file in net/ipv4 even using sudo.

Ubuntu Download Speeds Beat Windows XP's

lukas.mach what about packet loss? (515 comments)

Fine, what is this then:

Windows (Cygwin):

$ ping -n 20 www.google.com

Pinging www.l.google.com [74.125.39.147] with 32 bytes of data:
Reply from 74.125.39.147: bytes=32 time=12ms TTL=245
[...]
Ping statistics for 74.125.39.147:
Packets: Sent = 20, Received = 20, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds: Minimum = 11ms, Maximum = 41ms, Average = 16ms

Ubuntu:

lukas@9a:~$ ping www.google.com
PING www.l.google.com (74.125.39.147) 56(84) bytes of data.
64 bytes from fx-in-f147.google.com (74.125.39.147): icmp_seq=1 ttl=245 time=15.3 ms
--- www.l.google.com ping statistics ---
22 packets transmitted, 1 received, 95% packet loss, time 21003ms
rtt min/avg/max/mdev = 15.321/15.321/15.321/0.000 ms

Happens on my network no matter what I change - cables or notebooks, Vista runs ok, Ubuntu sucks big time. The only non-standard thing is that I have wired connection with manual IP address (connected by Linux based Asus router).

Open Firmware Released For Broadcom Wireless

lukas.mach Re:Cool (95 comments)

Is this really fair? Broadcom releases at least their ethernet drivers for Linux and Solaris as opensource. I expected that they do the same with they wifi drivers, but I don't really care about wifi.

Why Mirroring Is Not a Backup Solution

lukas.mach google cache (711 comments)

Can't they recover most of the posts by some resonably complex Google Cache data mining? Shouldn't be that hard.

Get on the 'Gates for President' Bandwagon

lukas.mach Re:Bill DID say he was leaving microsoft... (654 comments)

"The problem can be considered notable in cultural trivia, as the only well-known paper ever published by Microsoft Chairman and billionaire Bill Gates (as William Gates), entitled "Bounds for Sorting by Prefix Reversal", describes an efficient algorithm for pancake sorting. In addition, the only paper published by Futurama co-creator David X. Cohen (as David S. Cohen) concerned the burnt pancake problem. Their collaborators were Christos Papadimitriou (then at Harvard, now at Berkeley) and Manuel Blum (then at Berkeley, now at Carnegie Mellon University), respectively."
