Just to be explicit, PIE tends to have small (<1%) performance hits on register-starved architectures (i386) in most cases, for for certain work loads (e.g. python) the hit is large (~15%). On architectures with plenty of registers (amd64) there's virtually no measurable performance hit that I've seen. If your package handles 3rd party data of any kind (renders, network daemons, file parsers, etc), I strongly recommend enabling PIE. And, if you enable PIE, please enable bindnow too. The start-up performance hit of bindnow isn't measurable on most architectures. Some much slower ones can see problems (early ARM). It's possible that PIE and/or bindnow may be enabled by default for certain architectures in the future. If your package is using hardening-wrapper or hardening-includes, you were effectively using "+pie,+bindnow", so when converting, please continue to build with PIE and bindnow. :) Thanks! -Kees -- Kees Cook@debian.org -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe".

The project leads have the intention to port it to other VMs. But, if/when they do, the packaging will need to distinguish between the libraries for Parrot and the libraries for other languages. Maybe the solution is a source package named nqp, with different binary packages libparrot-nqp, libmono-nqp, etc... It's worth talking to Patrick about his plans. > Also, aren't parrot-nqp and nqp different things? (parrot-nqp is currently > used to build nqp). NQP has been through several major refactors.

CFLAGS and LDFLAGS (and CPPFLAGS and so on) are in my opionion normal things to be in a users environment, so a package's rules file should in my eyes not depend on them not being set or having any values sensible. So while I think dpkg-buildpackage not setting something there which could cause people to think using the environment in debian/rules for those is OK is better than dpkg-buildpackage setting them, I'd consider a dpkg-buildpackage that sets CFLAGS, CPPFLAGS and LDFLAGS all to "-fyour-rules-file-is-broken" even better.

It seems like 'libparrot-nqp' or 'parrot-nqp' might be the best fit. NQP is a parsing/matching library, written for Parrot, intended to be used as part of the compiler tool chain for languages implemented on top of Parrot. Otherwise, 'libperl-nqp'. The 'parrot-devel' package currently Provides 'parrot-nqp', which will have to change if NQP is moving out of the Parrot distribution into a separate distributed tarball and separate source package.

The key feature of NQP is that it's designed to be a very small compiler (as compared with, say, perl6 or Rakudo) and is focused on being a high-level way to create compilers and libraries for virtual machines (such as the Parrot Virtual Machine). . Unlike a full-fledged implementation of Perl 6, NQP strives to have as small a runtime footprint as it can, while still providing a Perl 6 object model and regular expression engine for the virtual machine. Note that this is needed by the upcoming version of rakudo.

In one sense, yes, we are providing a way to set these flags locally.

I agree that we need a good process for testing default build flags changes before propagating them. I'm not sure policy is the right forum, but debian-devel is.

Bug#643324: ITP: profphd -- secondary structure and solvent accessibility predictor
Package: wnpp Severity: wishlist Owner: Laszlo Kajan * Package name: profphd Version : 1.0.35 Upstream Author : Laszlo Kajan * URL : http://rostlab.org/ * License : GPL Programming Lang: Perl Description : secondary structure and solvent accessibility predictor Solvent accessibility is predicted by a neural network method rating at a correlation coefficient (correlation between experimentally observed and predicted relative solvent accessibility) of 0.54 cross-validated on a set of 238 globular proteins (Rost & Sander, Proteins, 1994, 20, 216-226; evaluation of accuracy). The output of the neural network codes for 10 states of relative accessibility. Expressed in units of the difference between prediction by homology modelling (best method) and prediction at random (worst method), PROFacc is some 26 percentage points superior to a comparable neural network using three output states (buried, intermediate, exposed) and using no information from multiple alignments. . Transmembrane helices in integral membrane proteins are predicted by a system of neural networks. The shortcoming of the network system is that often too long helices are predicted. These are cut by an empirical filter. The final prediction (Rost et al., Protein Science, 1995, 4, 521-533; evaluation of accuracy) has an expected per-residue accuracy of about 95%. The number of false positives, i.e., transmembrane helices predicted in globular proteins, is about 2%. . The neural network prediction of transmembrane helices (PHDhtm) is refined by a dynamic programming-like algorithm. This method resulted in correct predictions of all transmembrane helices for 89% of the 131 proteins used in a cross-validation test; more than 98% of the transmembrane helices were correctly predicted. The output of this method is used to predict topology, i.e., the orientation of the N-term with respect to the membrane. The expected accuracy of the topology prediction is > 86%. Prediction accuracy is higher than average for eukaryotic proteins and lower than average for prokaryotes. PHDtopology is more accurate than all other methods tested on identical data sets. -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
