Wow - this looks really really similar to my wrapper library (pgwrap [1]). See comment below [2] [1] https://github.com/paulchakravarti/pgwrap [2] https://news.ycombinator.com/item?id=11054944

It looks like a number of people have done something similar so though I would mention my attempt - pgwrap [1][2]. This is also a thin wrapper over psycopg2. This provides the following - * Simplified handling of connections/curs

Interestingly I just went through the same process as I wanted to understand how jails worked without the tools (my preference is iocage if you want something full featured - ez-jail doesn't properly handle the new jail.conf approach)

Probably not, but I would guess that the difference is well within the error margin of the original estimates.

I think that the real value is in forcing people to think about optimistic vs worst case estimates - in my experience the initial estimate is almost always actually the optimistic number and when they start to think about risks people tend

The fact that planning estimates represent a probability distribution is well known and there is an established process (PERT)[1] for estimating the expected time of a set of estimates - essentially instead of asking for a single 'most

A better analogy would be if the Jamestown settlers had spent 10 years floating in the English Channel being resupplied by rowing boat rather than actually getting on with the business of crossing the ocean and settling somewhere. The whole

Isn't there a simpler reason - a square design is easier to implement with a 3x3 matrix switch and the number layout ensures that the letters associated with the digits are in alphabetic order.

For dnslib [1] I use a much simpler fuzzer as part of the test suite [2] - this is nothing like as sophisticated as afl-fuzz or go-fuzz in terms of understanding and exercising code paths (just takes a DNS record and randomly mutates it - t

See libxo[1] There has been added in FreeBSD 11 but I am not sure how many of the commands have been converted. [1] https://juniper.github.io/libxo/libxo-manual.html

If you have dnslib installed ( https://pypi.python.org/pypi/dnslib ) you can also do something like: python3.4 -m dnslib.client --server <ns1> --diff <ns2> <domain> <type>

The Juniper libxo [1] library is an interesting approach which preserves the traditional text output but also gives an option to output structured data: The libxo library allows an application to generate text, XML, JSON, and HTML out

The AM355x already has 2 x 32bit Programmable Realtime Units (PRU) [1] so the AVR seems a bit redundant (other than compatibility with existing shields and ease of programming) [1] http://elinux.org/BeagleBone_PRU_Notes

This looks somewhat like the concept behind a fresnel zone plate [1] - in general these are highly dispersive (only work at one frequency) so it looks like they have done something to address this. Many (30+) years ago my final year project

I think that a lot of this depends on whether you want to run a desktop or server - a lot of comparisons focus on how Linux/FreeBSD compare as a user workstation. To be honest I wouldn't recommend anyone use FreeBSD as a desktop&#

Long time since I did any optics but this basically just convolution. The impact at the output plane of dust/imperfections on the lens is (approximately) a 2D fourier transform of the dust/imperfections. If you have a single dust

I'm a big fan of removing dependencies and very partial to distributing single dependency free executables, but don't you just need to install all the shellfire dependencies instead of Python/Ruby etc. Appreciate that you can

Absolutely right - Perl 4 had a clear niche (text processing, UNIX system scripting etc) and did this very well. Perl 5 added so much cruft and ugly syntax on top of this in an attempt to try to become more 'general purpose' that

Except that this is the opposite of my point - the libsodium repository is 9MB with 326 .c/.h files and c.25000 lines of code. Tweetnacl is 2 .c/.h files and c.1000 lines of code.

The easiest way to get round the slightly odd build environment for NaCl is to just use TweetNaCl ( http://tweetnacl.cr.yp.to/software.html ) which just requires you to drop a single .c/.h file into your project - this i
