Lunar: Reproducible builds: week 18 in Stretch cycle

What happened in the reproducible builds effort this week: Toolchain fixes Aur lien Jarno uploaded glibc/2.21-0experimental1 which will fix the issue were locales-all did not behave exactly like locales despite having it in the Provides field. Lunar rebased the pu/reproducible_builds branch for dpkg on top of the released 1.18.2. This made visible an issue with udebs and automatically generated debug packages. The summary from the meeting at DebConf15 between ftpmasters, dpkg mainatainers and reproducible builds folks has been posted to the revelant mailing lists. Packages fixed The following 70 packages became reproducible due to changes in their build dependencies: activemq-activeio, async-http-client, classworlds, clirr, compress-lzf, dbus-c++, felix-bundlerepository, felix-framework, felix-gogo-command, felix-gogo-runtime, felix-gogo-shell, felix-main, felix-shell-tui, felix-shell, findbugs-bcel, gco, gdebi, gecode, geronimo-ejb-3.2-spec, git-repair, gmetric4j, gs-collections, hawtbuf, hawtdispatch, jack-tools, jackson-dataformat-cbor, jackson-dataformat-yaml, jackson-module-jaxb-annotations, jmxetric, json-simple, kryo-serializers, lhapdf, libccrtp, libclaw, libcommoncpp2, libftdi1, libjboss-marshalling-java, libmimic, libphysfs, libxstream-java, limereg, maven-debian-helper, maven-filtering, maven-invoker, mochiweb, mongo-java-driver, mqtt-client, netty-3.9, openhft-chronicle-queue, openhft-compiler, openhft-lang, pavucontrol, plexus-ant-factory, plexus-archiver, plexus-bsh-factory, plexus-cdc, plexus-classworlds2, plexus-component-metadata, plexus-container-default, plexus-io, pytone, scolasync, sisu-ioc, snappy-java, spatial4j-0.4, tika, treeline, wss4j, xtalk, zshdb. The following packages became reproducible after getting fixed: Some uploads fixed some reproducibility issues but not all of them: Patches submitted which have not made their way to the archive yet: Chris Lamb also noticed that binaries shipped with libsilo-bin did not work. Documentation update Chris Lamb and Ximin Luo assembled a proper specification for SOURCE_DATE_EPOCH in the hope to convince more upstreams to adopt it. Thanks to Holger it is published under a non-Debian domain name. Lunar documented easiest way to solve issues with file ordering and timestamps in tarballs that came with tar/1.28-1. Some examples on how to use SOURCE_DATE_EPOCH have been improved to support systems without GNU date. reproducible.debian.net armhf is finally being tested, which also means the remote building of Debian packages finally works! This paves the way to perform the tests on even more architectures and doing variations on CPU and date. Some packages even produce the same binary Arch:all packages on different architectures (1, 2). (h01ger) Tests for FreeBSD are finally running. (h01ger) As it seems the gcc5 transition has cooled off, we schedule sid more often than testing again on amd64. (h01ger) disorderfs has been built and installed on all build nodes (amd64 and armhf). One issue related to permissions for root and unpriviliged users needs to be solved before disorderfs can be used on reproducible.debian.net. (h01ger) strip-nondeterminism Version 0.011-1 has been released on August 29th. The new version updates dh_strip_nondeterminism to match recent changes in debhelper. (Andrew Ayer) disorderfs disorderfs, the new FUSE filesystem to ease testing of filesystem-related variations, is now almost ready to be used. Version 0.2.0 adds support for extended attributes. Since then Andrew Ayer also added support to reverse directory entries instead of shuffling them, and arbitrary padding to the number of blocks used by files. Package reviews 142 reviews have been removed, 48 added and 259 updated this week. Santiago Vila renamed the not_using_dh_builddeb issue into varying_mtimes_in_data_tar_gz_or_control_tar_gz to align better with other tag names. New issue identified this week: random_order_in_python_doit_completion. 37 FTBFS issues have been reported by Chris West (Faux) and Chris Lamb. Misc. h01ger gave a talk at FrOSCon on August 23rd. Recordings are already online. These reports are being reviewed and enhanced every week by many people hanging out on #debian-reproducible. Huge thanks!

Lunar: Reproducible builds: week 17 in Stretch cycle

A good amount of the Debian reproducible builds team had the chance to enjoy face-to-face interactions during DebConf15.
Names in red and blue were all present at DebConf15
Picture of the  reproducible builds  talk during DebConf15
Hugging people with whom one has been working tirelessly for months gives a lot of warm-fuzzy feelings. Several recorded and hallway discussions paved the way to solve the remaining issues to get reproducible builds part of Debian proper. Both talks from the Debian Project Leader and the release team mentioned the effort as important for the future of Debian. A forty-five minutes talk presented the state of the reproducible builds effort. It was then followed by an hour long roundtable to discuss current blockers regarding dpkg, .buildinfo and their integration in the archive. Picture of the  reproducible builds  roundtable during DebConf15 Toolchain fixes Reiner Herrmann submitted a patch to make rdfind sort the processed files before doing any operation. Chris Lamb proposed a new patch for wheel implementing support for SOURCE_DATE_EPOCH instead of the custom WHEEL_FORCE_TIMESTAMP. akira sent one making man2html SOURCE_DATE_EPOCH aware. St phane Glondu reported that dpkg-source would not respect tarball permissions when unpacking under a umask of 002. After hours of iterative testing during the DebConf workshop, Sandro Knau created a test case showing how pdflatex output can be non-deterministic with some PNG files. Packages fixed The following 65 packages became reproducible due to changes in their build dependencies: alacarte, arbtt, bullet, ccfits, commons-daemon, crack-attack, d-conf, ejabberd-contrib, erlang-bear, erlang-cherly, erlang-cowlib, erlang-folsom, erlang-goldrush, erlang-ibrowse, erlang-jiffy, erlang-lager, erlang-lhttpc, erlang-meck, erlang-p1-cache-tab, erlang-p1-iconv, erlang-p1-logger, erlang-p1-mysql, erlang-p1-pam, erlang-p1-pgsql, erlang-p1-sip, erlang-p1-stringprep, erlang-p1-stun, erlang-p1-tls, erlang-p1-utils, erlang-p1-xml, erlang-p1-yaml, erlang-p1-zlib, erlang-ranch, erlang-redis-client, erlang-uuid, freecontact, givaro, glade, gnome-shell, gupnp, gvfs, htseq, jags, jana, knot, libconfig, libkolab, libmatio, libvsqlitepp, mpmath, octave-zenity, openigtlink, paman, pisa, pynifti, qof, ruby-blankslate, ruby-xml-simple, timingframework, trace-cmd, tsung, wings3d, xdg-user-dirs, xz-utils, zpspell. The following packages became reproducible after getting fixed: Uploads that might have fixed reproducibility issues: Some uploads fixed some reproducibility issues but not all of them: Patches submitted which have not made their way to the archive yet: St phane Glondu reported two issues regarding embedded build date in omake and cduce. Aur lien Jarno submitted a fix for the breakage of make-dfsg test suite. As binutils now creates deterministic libraries by default, Aur lien's patch makes use of a wrapper to give the U flag to ar. Reiner Herrmann reported an issue with pound which embeds random dhparams in its code during the build. Better solutions are yet to be found. reproducible.debian.net Package pages on reproducible.debian.net now have a new layout improving readability designed by Mattia Rizzolo, h01ger, and Ulrike. The navigation is now on the left as vertical space is more valuable nowadays. armhf is now enabled on all pages except the dashboard. Actual tests on armhf are expected to start shortly. (Mattia Rizzolo, h01ger) The limit on how many packages people can schedule using the reschedule script on Alioth has been bumped to 200. (h01ger) mod_rewrite is now used instead of JavaScript for the form in the dashboard. (h01ger) Following the rename of the software, debbindiff has mostly been replaced by either diffoscope or differences in generated HTML and IRC notification output. Connections to UDD have been made more robust. (Mattia Rizzolo) diffoscope development diffoscope version 31 was released on August 21st. This version improves fuzzy-matching by using the tlsh algorithm instead of ssdeep. New command line options are available: --max-diff-input-lines and --max-diff-block-lines to override limits on diff input and output (Reiner Herrmann), --debugger to dump the user into pdb in case of crashes (Mattia Rizzolo). jar archives should now be detected properly (Reiner Herrman). Several general code cleanups were also done by Chris Lamb. strip-nondeterminism development Andrew Ayer released strip-nondeterminism version 0.010-1. Java properties file in jar should now be detected more accurately. A missing dependency spotted by St phane Glondu has been added. Testing directory ordering issues: disorderfs During the reproducible builds workshop at DebConf, participants identified that we were still short of a good way to test variations on filesystem behaviors (e.g. file ordering or disk usage). Andrew Ayer took a couple of hours to create disorderfs. Based on FUSE, disorderfs in an overlay filesystem that will mount the content of a directory at another location. For this first version, it will make the order in which files appear in a directory random. Documentation update Dhole documented how to implement support for SOURCE_DATE_EPOCH in Python, bash, Makefiles, CMake, and C. Chris Lamb started to convert the wiki page describing SOURCE_DATE_EPOCH into a Freedesktop-like specification in the hope that it will convince more upstream to adopt it. Package reviews 44 reviews have been removed, 192 added and 77 updated this week. New issues identified this week: locale_dependent_order_in_devlibs_depends, randomness_in_ocaml_startup_files, randomness_in_ocaml_packed_libraries, randomness_in_ocaml_custom_executables, undeterministic_symlinking_by_rdfind, random_build_path_by_golang_compiler, and images_in_pdf_generated_by_latex. 117 new FTBFS bugs have been reported by Chris Lamb, Chris West (Faux), and Niko Tyni. Misc. Some reproducibility issues might face us very late. Chris Lamb noticed that the test suite for python-pykmip was now failing because its test certificates have expired. Let's hope no packages are hiding a certificate valid for 10 years somewhere in their source! Pictures courtesy and copyright of Debian's own paparazzi: Aigars Mahinovs.

Christian Perrier: 4621 potential "spams" left to review for me

A few of us are working on spam removal from Debian lists archives. The wiki page linked above explains how to report spam on Debian mailing lists. This is in short as easy as bouncing a mail to a specific address, from your favourite MUA. These "reported spams" then need to be reviewed. Once a given message has been identified as "spam" by enough DD's (there are many false positives in the candidates, particularly in non English-speaking mailing lists), it is removed from the archives. Many mails have already been removed and any help is welcomed. Since Frans Pop launched this for debian-boot, back in May, I use 1 or 2 hours every Sunday to this work. After working on debian-boot only, I gradually worked on reported spams in other lists. As of now, I only have 4 lists where I still have work to do: The Chinese and the Spanish ones are tricky because identifying spam there is much less easy (for Chinese, I'm quite conservative and only tag very obvious spam....for Spanish, I read enough of the language to be able to target spam). What about you? Will you be able to help the few of us who work on getting clean archives (noticeably, Sandro Tosi, Giacomo Catenazzi, Cord Beermann, Luk Claes, Frans Pop, Bastian Blank, Luca Falavigna, Michael Koch, Bernd Steinmetz, Thoomas Viehmann, Florian Ernst, Adam D. Barratt, to name thos ewho reviewed more than 1000 mails)? Working on lists in your own language might be a good idea (I'm particularly thinking about lists in German, Spanish, Chinese and French).

Cord Beermann: T-Online (German provider) enhances spam protection, and blocks legit listmail.

Just a quick pointer to an article in German for those 350+ Subscribers with a t-online-Mailaddress.

T-Online verbessert den Spamschutz - Legitime Mails werden abgelehnt.

Summary: T-Online now blocks non-spam Mail from Debians Listserver.

Cord Beermann: Geocaching with the n810

Today i tried the first time to do GeoCaching with my Nokia N810 running the Maemo (which is a Debian-based Distribution). I already own a Garmin Geko 201 with which i found 100+ Caches, so this is my reference.

The GPS-Receiver of the N810 is better than the one in the Geko (at least since i use the fixed gpsd, which normally shouldn't do something on the performance, but in my case... it made me feel better), so fixes come faster, and more accurate than on the Geko. (from hearsay the SirfIII-Chip is even better)

I run Maemo Mapper on the N810, a free (as in speech) Software written to do things better than GpsDrive at least on the Nokia Internet Tablets.

I wrote some programs to be the glue between Geocaching-Websites and GPSdrive (which depends on MySQL) and i modifed those to put the information into SQLite, which is the Database used by Maemo Mapper.
If i pump all my waypoints in such a file (which are currently 94607) Maemo Mapper gets slow. so slow that Maemo Mapper becomes useless.

On the Garmin-GPS-Receiver, i can have only 500 Waypoints, but i have a 'goto'-function, so i store my destination coordinates and say 'Goto' and the thing provides me an arrow which points to my destination and shows the distance (it doesn't know about ways so it points the direction directly, but that is usually fine as GeoCachers often are so abroad that no one has maps about the area.).

In Maemo Mapper i couldn't find such a function. I can say 'Goto Coordinates' and then it centers the map to there, but there isn't a sign and no line or arrow which direction i have to turn to. This is a problem (or something for the wishlist.)

So from GeoCachers view (and those people who want to navigate for other reasons) free Navigation-Software for Linux is an area where more work is needed.

Cord Beermann: being busy / Request for Help

Because of some modifications at my Real Life Orkplace, I decided to reduce other duties to get a better chance to deal with my new duties. So i requested help for my four packages in the Distribution

RFH: jove
My first package. A small, but powerful Emacs-relative, with all those uneeded things stripped which makes emacs fat. Maybe these days especially useful for small memory devices, as it gives you emacs-likeness for the price of nvi or ae. I have no idea how well it works in a real utf-8-environment.
RFH: milter-greylist
A greylist-milter which makes running a mailserver somehow possible for me. it keeps away about 2/3 of spam, which leaves me with only 400spams/day. I already have two contacts who want to help with that.
RFH: nn
No news is good news, but nn is better. This is a USENET reader, for those people who grow up with Webforums and Blogs: This could be still the most effective way to celebrate flamefests, gather information or communicate with people sharing same interests. And nn has in my opinion the best UI for it, and makes it easy and fast to find interesting articles and skip others. Well, Upstream Development has ceased to exist around 1994. I think if no one takes over, this package will become finally useless when IPv6 gets widely used (right after the release of 'Duke Nukem Forever') and it also doesn't deal well with non iso-8859-1-charsets. So best for this package would be to rewrite it from scratch (my dream: message/mime-handling/threading from mutt, scoring from slrn, and UI from nn) because the User Interface is much better than those of all still alive Newsreaders i tried.
RFA: synergy
This is my most popular package, which makes it possible to share one mouse and keyboard over many computers and displays. (It is available for UNIX/Linux, Windows and MacOS) This is a very very useful software, and i use it permanently. Sadly the Upstream Development mostly ceased to exist, and so i put this to RFA (instead of RFH) because many Debian-Users use it according to popcon. This software should be taken over by someone who is able to help Upstream. There is a RC-Bug, which caused the package be pulled from testing.

Interesting is that while filing those RFH/RFA all the same day, i only got responses for the packages which scores lowest in popcon, (24 for milter-greylist, 1196 for synergy).

25 January 2008

Cord Beermann: Today i kicked 560 Mailaddresses off lists.debian.org ...

... because they are bouncing.

In my ongoing attempt to investigate and fix problems of our mailinglist-server, i found that we only had a working bounce-detection for lists starting debian-* minus debian-private and the three digest-lists.

So i rewrote some parts of the bounce detection:

We now have four categories of lists:


for these four categories we calculate a spam-rate depending on the number of distributed messages and the number of bounces in the timerange of 24 hours for 'high' lists, 7 days for 'medium' lists, 30 days for 'low' lists and 90 days for 'very-low' lists.

If the Spamrate exceeds 80% for unmoderated, and 60% for moderated lists, and bounces have been seen for more than 24 hours we kick. (these rates are subject to change, when we have implemented the warning mechanism)

So these changes implemented a bounce-detection for debian-changes-digest and today we reached the level of 60% bounces for more than 500 subscribers.

So what next?

To finish the bounce-detection, i want to implement something which tries to notify subscribers about bouncing mails. This is useless for 'hard'-bouncers, but people with some smaller problems like mail2news-gatewayers this could be helpful. I also want to implement something which sends out unsubscription notices for three weeks after the kick, so kicked out people can resubscribe after they have sorted out the problems.

Both should fire once a week per address.

What do you think?

14 January 2008

Cord Beermann: Debian Lists vs. Mail2News-Gateways.

While analysing the pole setters in our internal bouncers-Hitlist i found that some of them run a mail2news-Gateway.

The problem is: our Mailinglists leave Mail-Headers mostly untouched, and so headers like X-Trace or X-Complaints-To are passed through without modifications.

If a mail containing those headers is handed over to inews (as in INN) it rejects it, and the bounce comes back to us:

<XXXXX@XXX.com>: Command died with status 1: "/usr/bin/maildrop". Command
output: inews: cannot send article to server: 441 Can't set system
"X-Complaints-To" header inews: article not posted


so people: fix your systems. if you do more with listmail than dropping it somewhere make sure that the bounces your system produces go to someone who can fix it. We (as in listmasters) normally simply unsubscribe those.

btw: we talk about 18181 bounces since 08.2004 in this case.

08 January 2008

Cord Beermann: Spamwaves on Lists or 'oops, i did it again'

Just a quick note:

while wading through the list-archives, drop-boxes and list-configuration to find false positives and possiblities to optimise our mailinglists spam level i accidently removed the inclusion of our spamfilters from most lists.

I appologise for this.

Luckily zobel discovered my error and fixed it at 14:30 CET.

02 January 2008

Cord Beermann: Precedence-Mail-Headers?

I'm just wadeing through Debian-Mailinglists on the search for enhancements and false-positives.

and i just came over debian-security-announce, a lists that sends a helpful message back to submitters that aren't allowed to send out advisories.

That message didn't contain a Precedence-Header so i added one, and wondered which value would be appropriate... I remember to have seen three values: 'junk', 'bulk' and 'list' (the latter should be set for all our Mailinglists).

So i tried the usual ways to find out about some more possible values, but i couldn't find a RfC or another Document that describes correct usage of the Precedence-Header.

So, i set the Header to 'junk' now, but if someone could point me to some documentation i would be thankful.

Update: formorer pointed me to RFC 3834 - Recommendations for Automatic Responses to Electronic Mail which contains all of the things i needed to know. Thank you.

Cord Beermann: mutt: autoviewing text/html

it sometimes funny, i'm working with mutt since about 10years, (the 5years before i was using elm) and just found out how i can view pure text/html-Mails without fiddeling with piping and things.

set implicit_autoview

in .muttrc does the trick.

but now mutt also prefers the text/html-part of multipart/alternative-mails, this is going to far for me. i want the text/plain-part if available. mutt has also a solution here:

alternative_order text/plain text/html

and done. no more piping to html2text. One day i'll read through the whole manual again...

Cord Beermann: sendmail uses ident be default

I have no idea how the other major MTAs handle this, but sendmail seems to issue an ident-auth-request on each connect it gets.

As i think this is rather useless, as most hosts don't answer it, and, even if they would, the answer is easily fakeable, i switched it off.

adding

define( confTO_IDENT', 0')dnl

to /etc/mail/sendmail.mc disables this. Sadly this isn't documented, for confTO_IDENT it only states
The timeout waiting for a response to an IDENT query.


thanks goes to http://sial.org/howto/sendmail/tips/

addendum: 'Your Name' in the comments is right. ident is still of some use on multiuser-systems to the local admin. But in the field of Internet-mailservers it is useless.

Cord Beermann: Analysis of subscribed Domains on Debian-Listserver.

From time to time we have the problem that a mail posted to a list triggers an autoresponse (vacation, bounce, tdma) from an unexpected source. Sometimes it isn't possible to identify the subscriber who is causing this. One example for this was 'petsupermarket'.

So i wrote a small tool, which takes Mailadresses as input and resolves the domains until it reaches IP-level, so it is possible to identify 'related' addresses to such an incident.

I now ran this tool for all 38656 domainparts mailadresses that are currently subscribed to some list at our listservers:

Unresolveable Domains                             :   443
Grounded Domains : 3
Domains with A : 1058
Domains with CNAME, A : 59
Domains with CNAME, CNAME, A : 3
Domains with MX, A : 36202
Domains with MX, CNAME, A : 1199
Domains with MX, CNAME, CNAME, A : 22
Domains with MX, CNAME, CNAME, CNAME, A : 5
Domains with MX, PTR : 36
Domains with unresolvable Hosts : 361


(You may have noticed that those lines doesn't sum up to 38656. It is possible to have more than one MX-Host, and it is also possible to have more than one IP in an A-Record. If one of those combinations falls into another category it is counted twice)

so we have 36528 domains that are completely configured correctly according to RfC 2821 with a MX-Record pointing to an A-Record, or without a MX-Record and an A-Record. These are 94.5% of all domains.

but we have 443 domains in our list, that didn't resolve at the moment i ran my script, those have to be investigated.

We also have 3 domains that are configured with 'IN MX 0 .' as decribed in this expired Draft, those also have to be investigated, and thrown out.

We have 1288 domains, which use CNAMEs (or CNAMEs pointing to CNAMEs) in their MX or directly on their domainname. RFC1034 says:

Domain names in RRs which point at another name should always point at the primary name and not the alias. This avoids extra indirections in accessing information.


then there are 36 domains which point their MX directly to an IP-Number. RFC 1035 says:

3.3.9. MX RDATA format

+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
PREFERENCE
+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
/ EXCHANGE /
/ /
+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+

where:

PREFERENCE A 16 bit integer which specifies the preference given to
this RR among others at the same owner. Lower values
are preferred.

EXCHANGE A <domain-name> which specifies a host willing to act as
a mail exchange for the owner name.

MX records cause type A additional section processing for the host
specified by EXCHANGE.


So according to that an MX has to point explicitely to a Full Qualified Domain Name, and it has to be an A-Record it points to.

However: Most MTAs (including ours) these days forgive this, and figure out the right thing.

At last: we have 361 Domains which MX and/or CNAME-Records point to Hostnames that are currently unresolvable. A quick check shows that often the problems only appear on one MX-Record, while another is correct, so the service is functional.

So maybe now it is a good idea and check your own DNS-Setup and the Mail-related Data.

Cord Beermann: Xlib: Maximum number of clients reached

Every two weeks i get this:

$ xterm &
Xlib: connection to ":0.0" refused by server
Xlib: Maximum number of clients reached
xterm Xt error: Can't open display: :0.0


and it looks that something eats up the possible number of Clients:

$ xlsclients wc -l

when i restart X i can open about 100 xterms until i reach the error message.

ideas?

The German parliament changed the law on 25th may 2007.

It's now forbidden to build, program, give, distribute or get software, which can be used to attack computers. that's something i do on a daily basis. (think nmap)

so it is only a question of time that i get caught.

Cord Beermann: Packaging Simple PHP Blog postponed.

We found out that Simple PHP Blog, the software that is used for this Blog, can't be packaged for Debian at the moment, because the License looks like this:

The Simple PHP Blog is released under the GNU Public License.

You are free to use and modify the Simple PHP Blog. All changes
must be uploaded to SourceForge.net under Simple PHP Blog.

Credit must be give to the original author and the Simple PHP Blog
logo graphic must appear on the site and link to the project
on SourceForge.net


So problems are (as far as i understand):



So i tried to explain this politely to Upstream, I hope he honors my request, as i really like this piece of software and want to see it in Debian.

MJ Ray: Feedback and Comments: long comments

When I have a longer comment on someone else's blog post, I usually write it up on my own site and then send a pingback or trackback. I've written my own really basic pingback and trackback clients and servers, which seem to work. I'll package them up Real Soon Now. Sooner if anyone asks for them. I don't have much sympathy with people who complain about losing comments because their Javascript or Cookies died when their own blog post has a stupid eyetest on it and its trackback settings are a bit screwed-up. Update: Cord Beermann commented:
"If you have a problem with the trackback function of my blog, then please be more specific what is wrong with the trackback function, because the software may be part of Debian soon."
Your page includes trackback:ping="" which seems obviously wrong.
"The 'stupid eyetest' however is a personal decision for my blog."
So what if it's a personal decision? It's stupid and I'm going to say that it's stupid. Are you the sort of guy who takes a personal decision to kick guys in wheelchairs, but then protests if they run over your foot in return? I'm disappointed if more stupid software is going to be in debian. Update 2: the image test seems to have been replaced by some numbers now. Thank you for removing the eyetest, but it still won't save a comment for some reason.
"However: both isn't related to the initial problem."
I think the broken trackback/pingback support is related to your initial problem. If your trackback/pingback support worked, you could use a real editor on your own site instead of a web browser on someone else's. In other news, here's Alexandre Vassalotti's review of Emacs weblogger-mode.
