Re: Looking back at 100 blog posts

I like this idea! I'm not so interested in tarsnap workflow (since it's still in the "public beta" phase, new website, etc). But I'm quite interested in the FreeBSD security workflow.

How much time do you spend on public/private email, how much time do you spend managing the security team (if at all -- and by "managing", I include both mentoring new members (if you do this at all) and assigning/discussing tasks)... and how much time do you spend actually looking at code?

I find that in LilyPond, actually working on the docs or build system is almost a relief; about 70% of my time is spent on emails and management. I'm wondering if that's something specific to documentation / website / releases (since the first two are much more "front-line" issues that are highly visible to users), or a general curse facing high-ranked members of open-source projects.

Posts about your personal workflow methods would be educational - email handling, task management, and perhaps even motivation.

Either you have directed your analytical skills towards developing these methods ... or such posts would provide an opportunity to do so.

I've often started a portupgrade run, and come back an hour later to see that it's been waiting for me to answer a configuration question. This can be especially frustrating when performing upgrades like this one on a system with many ports.

The solution is portupgrade's '-c' or '--config' option. It makes portupgrade ask you all of the config dialogs at the *beginning* of the portupgrade run. Much preferable.

So I recommend:

portupgrade -afc

Enjoy!

i will look into that issue asap. i had to rewrite several parts of the code to work on native win32/64, /dev/urandom was one "issue".

colin, have my mails reached your spam folder?

Yep - I should have said as much.

$ cat /dev/urandom | strings | head -1

Does /dev/urandom exist on your Cygwin machine?

$ uname -a
CYGWIN_NT-5.1 mycroft 1.5.25(0.156/4/2) 2008-06-12 19:34 i686 Cygwin

$ ./scrypt enc scrypt.h scrypt.h.enc
Please enter passphrase: Please confirm passphrase: scrypt: Error reading salt: No error

I threw some fprintfs into getsalt(), and neither successes nor failures seem to be triggered, which makes me think that something other than getsalt() is returning 4 to scryptenc_file. Take that with a giant grain of salt, though; I know about two weeks' worth of C. :-)

Yes, it now builds. Now getting the same error as da44en's Solaris 10 test:

scrypt: Error reading clocks: Invalid argument

If you edit config.h and take out the HAVE_SYS_ENDIAN_H line, does that unbreak the build?

Thanks! It looks like NetBSD only added RLIMIT_AS recently, in spite of it being required by POSIX. Could you try wrapping the RLIMIT_AS check in memlimit.c with #ifdef RLIMIT_AS ... #endif and let me know if that fixes the build?

Re: Gmail Sender header

Royce Williams — Fri, 11 Apr 2008 13:06:06 -0000

If the non-Google domain that you're using in Gmail has a published SPF record that doesn't include Google in its list of authorized sending IP space, perhaps this provides for a workaround?
