C'mon, I would prefer if the report was just another April Fools' Day joke...

Red Hat Clarifies Doubts Over UEFI Secure Boot Solution

luizd Just ask Flame developers (437 comments)

C'mon, it is very easy to solve the problem. Uses them same Microsoft CA that Flame worm is using.

SecureBoot is more a "reduce users power to change OS" than "protect from malwares", as Flame proved.

Oracle Not Satisfied With Potential $150,000; Goes Against Judge's Warning

luizd The next value will be... (234 comments)

See! it is obvious!

1) $ 6100000000 = 6,1e9
2) $ 2800000 = 2,8e6
3) $ 150000 = 1,5e5
4) ???

base series: 6.1, 2.8, 1.5... 0.91!
power series: 9, 6, 5... 4!
So: 0.91e4 or 9.1e3 or $ 9100

If I were Oracle, I'll be happy with the $ 150.000 offer.

Ask Slashdot: Best Wi-Fi Solution For a Hotel?

luizd Scale and be happy (300 comments)

Just buy a bunch of tp-link, replace its firmware with openwrt and do whatever you want: mesh, wds, etc...

Even if the hardware might not be as robust as a cisco, just multiply the number of units you buy. It's the same principle of RAID (redundant array of inexpensive discs). Just build an RMIR (redundant mesh of inexpensive routers)

Most Enterprises Plan To Be On IPv6 By 2013

luizd Re:Wrong survey audience (167 comments)

Individual coherence makes collective incoherence.

It is logical to not migrate as it costs and nobody uses it yet (but me). It does not add a think to your service, except if your end-user is a technical one (that for some reason, want IPv6). However, the logical "not migrate" movement creates a great incoherence when it introduces extra costs in order to overcome the lack of IPv4 when bad times comes. At that time, CFO will start to worry when the cost of IPv4 get skyrocketed.

So, if you migrate now and nobody does, you gain nothing. It only costs. If you do not migrate now and everybody else does, you gain as you postpone an investment without immediate return. When you migrate, it will be easier and cheaper. Now, it nobody migrates, we get doomed.

Who migrated until now are just people that like new technologies because they are new, even if they are worse. I migrated to IPv6 but it introduced extra lag as my ISP does not provide it and I'm using a tunnel.

New Approach For Laser Weapons

luizd Re:What if... (188 comments)

There must be some material that will reflect the laser beam. Isn't it necessary to generate the laser anyway? What about some lens shield that would use refraction with the help of some silver color? Ideally, it would be cool to see some counter-attack based on reflecting it back to source, varying a little bit around it. There must be something interesting to destroy around a laser cannon.

Boot Linux In Your Browser

luizd Javascript obfuscated (393 comments)

Very cool... but anybody noticed that this is not FOSS? Javascript code is obfuscated. This way, it would be difficult to change the code. Without custom made javascript code, it will only support all browsers but IE :-).

Comodo Says Two More RAs Compromised

luizd Re:Meaningless (144 comments)

That's the point! Just forget about omnipotent CAs. SSL certificates should be something like PGP. The trustness of it will be the result of a web of trust WOT. This would be very cool to see big companies doing campaign: sign my cert and get a discount/bonus/etc!

Cisco Linksys Routers Still Don't Support IPv6

luizd Re:ipv6 support on Cisco/Linksys routers (380 comments)

Also, there is OpenWRT. You can build a custom-made firmware with just what you need. You can fit ipv6 support and a web gui in 4MB of flash.

Become an SSLAdmin In a Few Easy Steps

luizd Re:Sometimes (64 comments)

OK, OK... now tell me if it makes any difference for your browser/app if the certificate is generated by some respected CA or a crappy one. There is no "trust level", just yes or no. Any CA can provide ANY certificate for ANY host. You control one CA, you control them all. If you can make any accepted CA generate the desired certificate, by bypassing identity validation, by political force, by social engineering, by whatever, SSL is just useless. It just protect you from someone a little more "powerful" than yourself. Correct me if I'm wrong but many respected CA can be persuaded by big countries, isn't it? How I love my PGP.

Coping With 1 Million SSH Authentication Failures?

luizd Re:Tar Pitting (497 comments)

Yes, I think that this is your best solution. Instead of using iptables directly, you should check your distribution software relative option.Generally is is easier (but anyway, it will ultimately result in the same iptables command)

Music While Programming?

luizd If it causes harm, it is less than prohibiting it (1019 comments)

I still remember once when I was programming while listening classical music. I started to type at the same rhythmic of it. As it was a quick one, my production was increased :-) I think it can change the production level for better or worse depending on the music. Prohibiting music is like any other kind of prohibition: It may (or not) work but with the expensive of a decrease of pleasure in working. Generally this would lead to a reduction in the production levels. For me, productively, it does not make sense to prohibit it.. As soon as it does not bother the others, music causes less harm than prohibiting it.

Chinese Hackers Targeting NYPD Computers

luizd Don't fell so special (212 comments)

"why are the Chinese so interested in the NYPD computer network?" It is not specific to NYPD. They even try to crack my home computer! It's more like a broadcast attack.

Distributed Storage Systems for Linux?

luizd Re:We use OpenAFS (52 comments)

Not anymore in OpenAFS 1.3.81.

Copied from release notes:

For UNIX, 1.3.81 is the latest version in the 1.4 release cycle. Starting
in 1.3.70, platforms with pthreads support provide a volserver which like
the fileserver and butc backup system uses pthreads. Solaris versions 8
and above, AIX, IRIX, OpenBSD, Darwin, MacOS and Linux clients support
large (>2gb) files, and provided fileservers have this option enabled.
HP-UX may also support large files, but has not yet been verified. We hope
sites which can do so will make use of 1.3.81 on their UNIX platforms and
provide feedback to help us fix any remaining issues before 1.4 is
released.
