Dirk Eddelbuettel: Rblpapi 0.3.1

The first update to the Rblpapi package since the initial CRAN upload in August is now available. Rblpapi connects R to the Bloomberg system, giving access to a truly vast array of time series data and custom calculations. This release brings a new beqs() functions to access the results from Bloomberg EQS queries, improves the build system a correct a bug in the retrieval of multiple tick series. The changes are detailed below.
Changes in Rblpapi version 0.3.1 (2015-10-19)
  • Added beqs() to run Bloomberg Equity Screen Search, based on initial PR #79 by Rademeyer Vermaak, reworked in PRs #83 and #84 by Dirk; closes tickets #63 and #80.
  • Bloomberg header and library files are now cached locally instead of being re-downloaded for every build (PR #78 by Dirk addressing issue #65).
  • For multiple ticks, time-stamps are unique-yfied before merging (PR #77 by Dirk addressing issue #76).
  • A compiler warning under new g++ versions is now suppressed (PR #69 by John, fixing #68).
Courtesy of CRANberries, there is also a diffstat report for the this release. As always, more detailed information is on the Rblpapi. Questions, comments etc should go to the issue tickets system at the GitHub repo.

Simon Richter: Bluetooth and Dual Boot

I still have a dual-boot installation because sometimes I need Windows for something (usually consulting work), and I use a Bluetooth mouse. Obviously, when I boot into Windows, it does not have the pairing information for the mouse, so I have to redo the entire pairing process, and repeat that when I get back to Linux. So, dear lazyweb: is there a way to share Bluetooth pairing information between multiple operating system installations?

Petter Reinholdtsen: Lawrence Lessig interviewed Edward Snowden a year ago

Last year, US president candidate in the Democratic Party Lawrence interviewed Edward Snowden. The one hour interview was published by Harvard Law School 2014-10-23 on Youtube, and the meeting took place 2014-10-20. The questions are very good, and there is lots of useful information to be learned and very interesting issues to think about being raised. Please check it out. I find it especially interesting to hear again that Snowden did try to bring up his reservations through the official channels without any luck. It is in sharp contrast to the answers made 2013-11-06 by the Norwegian prime minister Erna Solberg to the Norwegian Parliament, claiming Snowden is no Whistle-Blower because he should have taken up his concerns internally and using official channels. It make me sad that this is the political leadership we have here in Norway.

Lunar: Reproducible builds: week 25 in Stretch cycle

What happened in the reproducible builds effort this week: Toolchain fixes Niko Tyni wrote a new patch adding support for SOURCE_DATE_EPOCH in Pod::Man. This would complement or replace the previously implemented POD_MAN_DATE environment variable in a more generic way. Niko Tyni proposed a fix to prevent mtime variation in directories due to debhelper usage of cp --parents -p. Packages fixed The following 119 packages became reproducible due to changes in their build dependencies: aac-tactics, aafigure, apgdiff, bin-prot, boxbackup, calendar, camlmix, cconv, cdist, cl-asdf, cli-common, cluster-glue, cppo, cvs, esdl, ess, faucc, fauhdlc, fbcat, flex-old, freetennis, ftgl, gap, ghc, git-cola, globus-authz-callout-error, globus-authz, globus-callout, globus-common, globus-ftp-client, globus-ftp-control, globus-gass-cache, globus-gass-copy, globus-gass-transfer, globus-gram-client, globus-gram-job-manager-callout-error, globus-gram-protocol, globus-gridmap-callout-error, globus-gsi-callback, globus-gsi-cert-utils, globus-gsi-credential, globus-gsi-openssl-error, globus-gsi-proxy-core, globus-gsi-proxy-ssl, globus-gsi-sysconfig, globus-gss-assist, globus-gssapi-error, globus-gssapi-gsi, globus-net-manager, globus-openssl-module, globus-rsl, globus-scheduler-event-generator, globus-xio-gridftp-driver, globus-xio-gsi-driver, globus-xio, gnome-control-center, grml2usb, grub, guilt, hgview, htmlcxx, hwloc, imms, kde-l10n, keystone, kimwitu++, kimwitu-doc, kmod, krb5, laby, ledger, libcrypto++, libopendbx, libsyncml, libwps, lprng-doc, madwimax, maria, mediawiki-math, menhir, misery, monotone-viz, morse, mpfr4, obus, ocaml-csv, ocaml-reins, ocamldsort, ocp-indent, openscenegraph, opensp, optcomp, opus, otags, pa-bench, pa-ounit, pa-test, parmap, pcaputils, perl-cross-debian, prooftree, pyfits, pywavelets, pywbem, rpy, signify, siscone, swtchart, tipa, typerep, tyxml, unison2.32.52, unison2.40.102, unison, uuidm, variantslib, zipios++, zlibc, zope-maildrophost. The following packages became reproducible after getting fixed: Packages which could not be tested: Some uploads fixed some reproducibility issues but not all of them: Patches submitted which have not made their way to the archive yet: Lunar reported that test strings depend on default character encoding of the build system in ongl. reproducible.debian.net The 189 packages composing the Arch Linux core repository are now being tested. No packages are currently reproducible, but most of the time the difference is limited to metadata. This has already gained some interest in the Arch Linux community. An explicit log message is now visible when a build has been killed due to the 12 hours timeout. (h01ger) Remote build setup has been made more robust and self maintenance has been further improved. (h01ger) The minimum age for rescheduling of already tested amd64 packages has been lowered from 14 to 7 days, thanks to the increase of hardware resources sponsored by ProfitBricks last week. (h01ger) diffoscope development diffoscope version 37 has been released on October 15th. It adds support for two new file formats (CBFS images and Debian .dsc files). After proposing the required changes to TLSH, fuzzy hashes are now computed incrementally. This will avoid reading entire files in memory which caused problems for large packages. New tests have been added for the command-line interface. More character encoding issues have been fixed. Malformed md5sums will now be compared as binary files instead of making diffoscope crash amongst several other minor fixes. Version 38 was released two days later to fix the versioned dependency on python3-tlsh. strip-nondeterminism development strip-nondeterminism version 0.013-1 has been uploaded to the archive. It fixes an issue with nonconformant PNG files with trailing garbage reported by Roland Rosenfeld. disorderfs development disorderfs version 0.4.1-1 is a stop-gap release that will disable lock propagation, unless --share-locks=yes is specified, as it still is affected by unidentified issues. Documentation update Lunar has been busy creating a proper website for reproducible-builds.org that would be a common location for news, documentation, and tools for all free software projects working on reproducible builds. It's not yet ready to be published, but it's surely getting there. Homepage of the future reproducible-builds.org website  Who's involved?  page of the future reproducible-builds.org website Package reviews 103 reviews have been removed, 394 added and 29 updated this week. 72 FTBFS issues were reported by Chris West and Niko Tyni. New issues: random_order_in_static_libraries, random_order_in_md5sums.

Hideki Yamane: Who freezes my laptop?

After reboot, suddenly my laptop cannot boot :-(
Then, tried to login rescue mode but root account is disabled.

Then, use USBstick to boot Ubuntu and mount encrypted volume, make root enabled.

After checking syslog, libvirt calls dmidecode and it seems that something is wrong with it.

Removed gnome-boxes and libvirt*, reboot my system and I can see login dialog by gdm3.

However, after login, I tried to exec dmidecode but nothing happened.

Also installing gnome-boxes and libvirt* packages and reboot is okay.

Okay, back to nomal. But....hmmm...? Who stole my time??

Sven Hoexter: TclCurl snapshot uploaded to unstable

While I was pondering if I should drop the tclcurl package and get it removed from Debian Christian Werner from Androwish (a Tcl/Tk port for Android) started to fix the open bugs. Thanks a lot Christian! I've now uploaded a new TclCurl package to unstable based on the code in the new upstream repository plus the patches from Christian. In case you're one of the few TclCurl users out there please try the new package. I'm still pondering if it's worth to keep the package. For the last five years or so I could get along with the Tcl http module just fine and thus no longer use TclCurl myself. In case someone would like to adopt it just write me a mail, I'd be happy to give it away.

Simon Richter: Key Transition

So, since several years I've had a second gpg key, 4096R/6AABE354. Several of you have already signed it, and I've been using it in Debian for some time already, but I've not announced it more widely yet, and I occasionally still get mail encrypted to the old key (which remains valid and usable, but it's 1024R). Of course, I've also made a formal transition statement:
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
OpenPGP Key Transition Statement for Simon Richter
I have created a new OpenPGP key and will be transitioning away from
my old key.  The old key has not been compromised and will continue to
be valid for some time, but I prefer all future correspondence to be
encrypted to the new key, and will be making signatures with the new
key going forward.
I would like this new key to be re-integrated into the web of trust.
This message is signed by both keys to certify the transition.  My new
and old keys are signed by each other.  If you have signed my old key,
I would appreciate signatures on my new key as well, provided that
your signing policy permits that without re-authenticating me.
The old key, which I am transitioning away from, is:
pub   1024D/5706A4B4 2002-02-26
      Key fingerprint = 040E B5F7 84F1 4FBC CEAD  ADC6 18A0 CC8D 5706 A4B4
The new key, to which I am transitioning, is:
pub   4096R/6AABE354 2009-11-19
      Key fingerprint = 9C43 2534 95E4 DCA8 3794  5F5B EBF6 7A84 6AAB E354
The entire key may be downloaded from: http://www.simonrichter.eu/simon.asc
To fetch the full new key from a public key server using GnuPG, run:
  gpg --keyserver keys.gnupg.net --recv-key 6AABE354
If you already know my old key, you can now verify that the new key is
signed by the old one:
  gpg --check-sigs 6AABE354
If you are satisfied that you've got the right key, and the User IDs
match what you expect, I would appreciate it if you would sign my key:
  gpg --sign-key 6AABE354
You can upload your signatures to a public keyserver directly:
  gpg --keyserver keys.gnupg.net --send-key 6AABE354
Or email sr@simonrichter.eu (possibly encrypted) the output from:
  gpg --armor --export 6AABE354
If you'd like any further verification or have any questions about the
transition please contact me directly.

Joey Hess: it's a bird, it's a plane, it's a super monoid for propellor

I've been doing a little bit of dynamically typed programming in Haskell, to improve Propellor's Info type. The result is kind of interesting in a scary way. Info started out as a big record type, containing all the different sorts of metadata that Propellor needed to keep track of. Host IP addresses, DNS entries, ssh public keys, docker image configuration parameters... This got quite out of hand. Info needed to have its hands in everything, even types that should have been private to their module. To fix that, recent versions of Propellor let a single Info contain many different types of values. Look at it one way and it contains DNS entries; look at it another way and it contains ssh public keys, etc. As an migr from lands where you can never know what type of value is in a $foo until you look, this was a scary prospect at first, but I found it's possible to have the benefits of dynamic types and the safety of static types too. The key to doing it is Data.Dynamic. Thanks to Joachim Breitner for suggesting I could use it here. What I arrived at is this type (slightly simplified):
newtype Info = Info [Dynamic]
    deriving (Monoid)
So Info is a monoid, and it holds of a bunch of dynamic values, which could each be of any type at all. Eep! So far, this is utterly scary to me. To tame it, the Info constructor is not exported, and so the only way to create an Info is to start with mempty and use this function:
addInfo :: (IsInfo v, Monoid v) => Info -> v -> Info
addInfo (Info l) v = Info (toDyn v : l)
The important part of that is that only allows adding values that are in the IsInfo type class. That prevents the foot shooting associated with dynamic types, by only allowing use of types that make sense as Info. Otherwise arbitrary Strings etc could be passed to addInfo by accident, and all get concated together, and that would be a total dynamic programming mess. Anything you can add into an Info, you can get back out:
getInfo :: (IsInfo v, Monoid v) => Info -> v
getInfo (Info l) = mconcat (mapMaybe fromDynamic (reverse l))
Only monoids can be stored in Info, so if you ask for a type that an Info doesn't contain, you'll get back mempty. Crucially, IsInfo is an open type class. Any module in Propellor can make a new data type and make it an instance of IsInfo, and then that new data type can be stored in the Info of a Property, and any Host that uses the Property will have that added to its Info, available for later introspection.
For example, this weekend I'm extending Propellor to have controllers: Hosts that are responsible for running Propellor on some other hosts. Useful if you want to run propellor once and have it update the configuration of an entire network of hosts. There can be whole chains of controllers controlling other controllers etc. The problem is, what if host foo has the property controllerFor bar and host bar has the property controllerFor foo? I want to avoid a loop of foo running Propellor on bar, running Propellor on foo, ... To detect such loops, each Host's Info should contain a list of the Hosts it's controlling. Which is not hard to accomplish:
newtype Controlling = Controlled [Host]
    deriving (Typeable, Monoid)
isControlledBy :: Host -> Controlling -> Bool
h  isControlledBy  (Controlled hs) = any (== hostName h) (map hostName hs)
instance IsInfo Controlling where
    propigateInfo _ = True
mkControllingInfo :: Host -> Info
mkControllingInfo controlled = addInfo mempty (Controlled [controlled])
getControlledBy :: Host -> Controlling
getControlledBy = getInfo . hostInfo
isControllerLoop :: Host -> Host -> Bool
isControllerLoop controller controlled = go S.empty controlled
  where
    go checked h
          controller  isControlledBy  c = True
        -- avoid checking loops that have been checked before
          hostName h  S.member  checked = False
          otherwise = any (go (S.insert (hostName h) checked)) l
      where
        c@(Controlled l) = getControlledBy h
This is all internal to the module that needs it; the rest of propellor doesn't need to know that the Info is using used for this. And yet, the necessary information about Hosts is gathered as propellor runs.
So, that's a useful technique. I do wonder if I could somehow make addInfo combine together values in the list that have the same type; as it is the list can get long. And, to show Info, the best I could do was this:
 instance Show Info where
            show (Info l) = "Info " ++ show (map dynTypeRep l)
The resulting long list of the types of vales stored in a host's info is not a useful as it could be. Of course, getInfo can be used to get any particular type of value:
*Main> hostInfo kite
Info [InfoVal System,PrivInfo,PrivInfo,Controlling,DnsInfo,DnsInfo,DnsInfo,AliasesInfo, ...
*Main> getInfo (hostInfo kite) :: AliasesInfo
AliasesInfo (fromList ["downloads.kitenet.net","git.joeyh.name","imap.kitenet.net","nntp.olduse.net" ...
And finally, I keep trying to think of a better name than "Info".

Iustin Pop: Server upgrades and monitoring

Undecided whether the title should be "exercises in Yak shaving" or "paying back technical debt" or "too much complexity for personal systems". Anyway I started hosting my personal website and some other small stuff on a dedicated box (rented from a provider) in early 2008. Even for a relatively cheap box, it worked without issues for a good number of years. A surprising number of years, actually; the only issue was a power supply failure that was solved by the provider automatically and then nothing for many years. Even the harddrive (mechanical) had no issues at all for 7 years (Power_On_Hours: 64380; I probably got it after it had a few months of uptime). I believe it was the longest running harddrive I've ever used (for the record: Seagate Barracuda 7200.10, ST3250310AS). The reason I delayed upgrade for a long time was twofold: first, at the same provider I couldn't get a similar SLA for the same amount of money. I could get better hardware, but with worse SLA and options. This is easily solvable, of course, by just finding a different provider. The other issue was that I never bothered to setup proper configuration management for the host; after all, it was only supposed to run Apache with ikiwiki and some other trivial small other things. The truth was that over time it started pilling up more and more "small things" so actually changing the host is expensive. As the age of the server neared 7 years, I thought to combine upgrade from Wheezy to Jessie with a HW upgrade. Managed to find a different provider that had my desired SLA and HW configuration, got the server and the only thing left was to do the migration. Previous OS upgrades were simple as they were on the same host; i.e. rely on Debian's reliable upgrade and nothing else to, eventually adjust slightly some configs. With a cross-host upgrade (I couldn't just copy the old OS since it was also a 32-to-64 bit change) it's much worse: since there's no previous installation, I had to manually check and port the old configuration for each individual service. This got very tedious, and I realised I have to make it somehow better. "Proper" configuration management aside, I thought that I need proper monitoring first. I already had (for a long while actually) graphing via Munin, but no actual monitoring. Since the host only had few services, this was again supposed to be easy - same mistake again. The problem is that once you have any monitoring system setup, it's very easy to actually add "just one more" host or service to it. First it was only the external box, then it was my firewall, then it was the rest of my home network. Then it was the cloud services that I use for example, checking whether my domain registrar's nameservers still are authoritative for my domain or whether the expiration date it still far in the future. And so on In the end, what was in previous iterations (e.g. Squeeze to Wheezy upgrade) a half-weekend job only, spread out over many weekends (interleaved with other activities, not fully working on it). I had to keep the old machine running for a month more in order to make sure everything was up and running, and I ended up with 80 services monitored across multiple systems; the migrated machine itself has almost half of these. Some of these are light items (e.g. a checking that a single vhost responds) other are aggregates. I still need to add some more checks though, especially more complex (end-to-end) ones. The lesson I learned in all this is that, with or without configuration management in place, having monitoring makes it much easier do to host or service moves, as you know much better when everything is done whether it's "done-done" or just "almost done". The question that remains though: with 80 services for a home network plus external systems (personal use); I'm not sure if I'm doing things right (monitor the stuff I need) or wrong (do I really need these many things)?

Russell Coker: Mail Server Training

Today I ran a hands-on training session on configuring a MTA with Postfix and Dovecot for LUV. I gave each student a virtual machine running Debian/Jessie with full Internet access and instructions on how to configure it as a basic mail server. Here is a slightly modified set of instructions that anyone can do on their own system. Today I learned that documentation that includes passwords on a command-line should have quotes around the password, one student used a semi-colon character in his password which caused some confusion (it s the command separator character in BASH). I also discovered that trying to just tell users which virtual server to login to is prone to errors, in future I ll print out a list of user-names and passwords for virtual servers and tear off one for each student so there s no possibility of 2 users logging in to the same system. I gave each student a sub-domain of unixapropos.com (a zone that I use for various random sysadmin type things). I have changed the instructions to use example.com which is the official address for testing things (or you could use any zone that you use). The test VMs that I setup had a user named auser , the documentation assumes this account name. You could change auser to something else if you wish. Below are all the instructions for anyone who wants to try it at home or setup virtual machines and run their own training session. Basic MTA Configuration
  1. Run apt-get install postfix to install Postfix, select Internet Site for the type of mail configuration and enter the domain name you selected for the mail name.
  2. The main Postfix configuration file is /etc/postfix/main.cf. Change the myhostname setting to the fully qualified name of the system, something like mta.example.com.
    You can edit /etc/postfix/main.cf with vi (or any other editor) or use the postconf command to change it, eg postconf -e myhostname=mta.example.com .
  3. Add home_mailbox=Maildir/ to the Postfix configuration to make it deliver to a Maildir spool in the user s home directory.
  4. Restart Postfix to apply the changes.
  5. Run apt-get install swaks libnet-ssleay-perl to install swaks (a SMTP test tool).
  6. Test delivery by running the command swaks -f auser@example.com -t auser@example.com -s localhost . Note that swaks displays the SMTP data so you can see exactly what happens and if something goes wrong you will see everything about the error.
  7. Inspect /var/log/mail.log to see the messages about the delivery. View the message which is in ~auser/Maildir/new.
  8. When other students get to this stage run the same swaks command but with the -t changed to the address in their domain, check the mail.log to see that the messages were transferred and view the mail with less to see the received lines. If you do this on your own specify a recipient address that s a regular email address of yours (EG a Gmail account).
Basic Pop/IMAP Configuration
  1. Run apt-get install dovecot-pop3d dovecot-imapd to install Dovecot POP and IMAP servers.
    Run netstat -tln to see the ports that have daemons listening on them, observe that ports 110 and 143 are in use.
  2. Edit /etc/dovecot/conf.d/10-mail.conf and change mail_location to maildir:~/Maildir . Then restart Dovecot.
  3. Run the command nc localhost 110 to connect to POP, then run the following commands to get capabilities, login, and retrieve mail:
    user auser
    pass WHATEVERYOUMADEIT
    capa
    list
    retr 1
    quit
  4. Run the command nc localhost 143 to connect to IMAP, then run the following commands to list capabilities, login, and logout:
    a capability
    b login auser WHATEVERYOUMADEIT
    c logout
  5. For the above commands make note of the capabilities, we will refer to that later.
Now you have a basically functional mail server on the Internet! POP/IMAP Over SSL To avoid password sniffing we need to use SSL. To do it properly requires obtaining a signed key for a DNS address but we can do the technical work with the snakeoil certificate that is generated by Debian.
  1. Edit /etc/dovecot/conf.d/10-ssl.conf and change ssl = no to ssl = required . Then add the following 2 lines:
    ssl_cert = </etc/ssl/certs/ssl-cert-snakeoil.pem
    ssl_key = </etc/ssl/private/ssl-cert-snakeoil.key
    1. Run netstat -tln and note that ports 993 and 995 are not in use.
    2. Edit /etc/dovecot/conf.d/10-master.conf and uncomment the following lines:
      port = 993
      ssl = yes
      port = 995
      ssl = yes
    3. Restart Dovecot, run netstat -tln and note that ports 993 and 995 are in use.
  2. Run nc localhost 110 and nc localhost 143 as before, note that the capabilities have changed to include STLS/STARTTLS respectively.
  3. Run gnutls-cli --tofu 127.0.0.1 -p 993 to connect to the server via IMAPS and gnutls-cli --tofu 127.0.0.1 -p 995 to connect via POP3S. The --tofu option means to Trust On First Use , it stores the public key in ~/.gnutls and checks it the next time you connect. This allows you to safely use a snakeoil certificate if all apps can securely get a copy of the key.
Postfix SSL
  1. Edit /etc/postfix/main.cf and add the following 4 lines:
    smtpd_tls_received_header = yes
    smtpd_tls_loglevel = 1
    smtp_tls_loglevel = 1
    smtp_tls_security_level = may
    Then restart Postfix. This makes Postfix log TLS summary messages to syslog and in the Received header. It also permits Postfix to send with TLS.
  2. Run nc localhost 25 to connect to your SMTP port and then enter the following commands:
    ehlo test
    quit
    Note that the response to the EHLO command includes 250-STARTTLS, this is because Postfix was configured with the Snakeoil certificate by default.
  3. Run gnutls-cli --tofu 127.0.0.1 -p 25 -s and enter the following commands:
    ehlo test
    starttls
    ^D
    After the CTRL-D gnutls-cli will establish a SSL connection.
  4. Run swaks -tls -f auser@example.com -t auser@example.com -s localhost to send a message with SSL encryption. Note that swaks doesn t verify the key.
  5. Try using swaks to send messages to other servers with SSL encryption. Gmail is one example of a mail server that supports SSL which can be used, run swaks -tls -f auser@example.com -t YOURADDRESS@gmail.com to send TLS (encapsulated SSL) mail to Gmail via swaks. Also run swaks -tls -f auser@example.com -t YOURADDRESS@gmail.com -s localhost to send via your new mail server (which should log that it was a TLS connection from swaks and a TLS connection to Gmail).
SASL SASL is the system of SMTP authentication for mail relaying. It is needed to permit devices without fixed IP addresses to send mail through a server. The easiest way of configuring Postfix SASL is to have Dovecot provide it s authentication data to Postfix. Among other things if you change Dovecot to authenticate in another way you won t need to make any matching changes to Postfix.
  1. Run mkdir -p /var/spool/postfix/var/spool and ln -s ../.. /var/spool/postfix/var/spool/postfix , this allows parts of Postfix to work with the same configuration regardless of whether they are running in a chroot.
  2. Add the following to /etc/postfix/main.cf and restart Postfix:
    smtpd_sasl_auth_enable = yes
    smtpd_sasl_type = dovecot
    smtpd_sasl_path = /var/spool/postfix/private/auth
    broken_sasl_auth_clients = yes
    smtpd_sasl_authenticated_header = yes
  3. Edit /etc/dovecot/conf.d/10-master.conf, uncomment the following lines, and then restart Dovecot:
    unix_listener /var/spool/postfix/private/auth
    mode = 0666
  4. Edit /etc/postfix/master.cf, uncomment the line for the submission service, and restart Postfix. This makes Postfix listen on port 587 which is allowed through most firewalls.
  5. From another system (IE not the virtual machine you are working on) run swaks -tls -f auser@example.com -t YOURADDRESS@gmail.com -s YOURSERVER and note that the message is rejected with Relay access denied .
  6. Now run swaks -tls --auth-user auser --auth-password WHATEVER -f auser@example.com -t YOURREALADDRESS -s YOURSERVER and observe that the mail is delivered (subject to anti-spam measures at the recipient).
  7. Configuring a MUA If every part of the previous 3 sections is complete then you should be able to setup your favourite MUA. Use auser as the user-name for SMTP and IMAP, mail.example.com for the SMTP/IMAP server and it should just work! Of course you need to use the same DNS server for your MUA to have this just work. But another possibility for testing is to have the MUA talk to the server by IP address not by name.

Steve Kemp: Robbing Peter to pay Paul, or location spoofing via DNS

I rarely watched TV online when I was located in the UK, but now I've moved to Finland with appalling local TV choices it has become more common. The biggest problem with trying to watch BBC's iPlayer, and similar services, is the location restrictions. Not a huge problem though: The next part is the harder one - making your traffic pass over the VPN. If you were simple you'd just say "Send everything over the VPN". But that would slow down local traffic, so instead you have to use trickery. My approach was just to run a series of routing additions, similar to this (except I did it in the openvpn configuration, via pushed-routes):
ip -4 route add .... dev tun0
This works, but it is a pain as you have to add more and more routes. The simpler solution which I switched to after a while was just configuring mitmproxy on the remote OpenVPN end-point, and then configuring that in the browser. With that in use all your traffic goes over the VPN link, if you enable the proxy in your browser, but nothing else will. I've got a network device on-order, which will let me watch netflix, etc, from my TV, and I'm lead to believe this won't let you setup proxies, or similar, to avoid region-bypass. It occurs to me that I can configure my router to give out bogus DNS responses - if the device asks for "iplayer.bbc.com" it can return 10.10.10.10 - which is the remote host running the proxy. I imagine this will be nice and simple, and thought I was being clever: Because I can handle DNS-magic on the router I can essentially spoof my location for all the devices on the internal LAN, which is a good thing. Anyway I was reasonably pleased with the idea of using DNS to route traffic over the VPN, in combination with a transparent proxy. I was even going to blog about it, and say "Hey! This is a cool idea I've never heard of before". Instead I did a quick google(.fi) and discovered that there are companies offering this as a service. They don't mention the proxying bit, but it's clearly what they're doing - for example OverPlay's SmartDNS. So in conclusion I can keep my current setup, or I can use the income I receive from DNS hosting to pay for SmartDNS, or other DNS-based location-fakers. Regardless. DNS. VPN. Good combination. Try it if you get bored.

Francois Marier: Introducing reboot-notifier for jessie and stretch

One of the packages that got lost in the transition from Debian wheezy to jessie was the update-notifier-common package which could be used to receive notifications when a reboot is needed (for example, after installing a kernel update). I decided to wrap this piece of functionality along with a simple cron job and create a new package: reboot-notifier. Because it uses the same file (/var/run/reboot-required) to indicate that a reboot is needed, it should work fine with any custom scripts that admins might have written prior to jessie. If you're running sid or strech, all you need to do is:
apt install reboot-notifier
On jessie, you'll need to add the backports repository to /etc/apt/sources.list:
deb http://httpredir.debian.org/debian jessie-backports main

Vincent Sanders: Raspberries are not the only fruit

I have worked with ARM based systems for longer than I care to admit to myself. From the Acorn Archimedes 305 in 1987 through to modern 64bit systems I have seen many many changes in the ARM community. One big change has been the rise of the inexpensive single board computer (SBC).

Arguably the Raspberry Pi (RPi) was responsible for starting this trend. Before RPi there were small development boards available, I was even involved in producing some of them, none of these really became a big thing and were principally vehicles for silicon vendors to showcase their SoC in an accessible way. When I say accessible I mean for silicon vendors who were previously used to charging many thousands of pounds for their development boards now only charging hundreds.

Raspberry Pi 2 B+ in my case
In my opinion the RPi was a complete disruption to the SBC market. In early 2012 a complete ARM computer system could now be purchased for $35 ( 25) which was substantially cheaper than the best contemporary competitor the Beaglebone $89 ( 60)

To be clear, the reason the RPi succeeded (millions sold, household name) was not on price alone but also the large amount of good supporting software and how easy it was made for teachers and makers to use.

There were several areas that the RPi managed to change perceived issues into opportunities for using what was already available or third parties to provide. There were also several issues raised about the original RPi:
Some of these have been addressed since release as the foundation now sells cases, hardware revisions with much more powerful processors, pre-configured storage, cameras and displays. The important thing to note here though is the RPi has made the bare SBC a much more widely accepted product where all the non critical parts are considered "extras" and a lot is forgiven because of the price.

With that acceptance there have been many, many new SBC coming to market with better peripherals and increasingly competitive pricing. These are technically not clones as none of them use the Broadcom processor of the RPi but they often share many features and possibly even a compatible expansion header.

Banana pi in my case with a 2.5inch drive bay
The Banana Pi was one of these copycats which I acquired for a similar price as an RPi in 2014. The main processor of this system was a 1Ghz dual core Allwinner A20 processor (a considerable advance on the 700MHz single core of the original RPi) coupled to a gigabyte of memory. Additionally the board benefited from having SATA and gigabit Ethernet MAC which made for a much more versatile system. Various third parties filled in the missing peripherals including my own attempt at a case.

I acquired a cubietruck for the NetSurf project to use as a build node in their CI system this is again based on the A20 but with more memory and somewhat better peripheral support but at a substantial cost over the Banana Pi.

The most recent addition to this form factor is the introduction by Xunlong Software of the Orange Pi PC. This little board is the same footprint as the RPi2 B+ design but with differing connector placement. The processor is a quad core 1.6GHz Allwinner H3 with a gigabyte of memory and has has Ethernet and USB but no SATA.

Pile of Orange Pi PC in my cases
The big news about this board though is the price, at $15 ( 10) it resets the price expectations just as the RPi did before it. I was initially sceptical of the quality of the product (or if it would arrive at all) but I have acquired five of these boards and every one of them came well packaged, boxed and in a static bag, just like the RPi does, and they all worked.

I created a case design based on my RPi slimline case so they would be protected when piled up with all the other boards. The use of a DC barrel jack instead of micro USB for power is better in that the connector is more robust and intended for higher current draws but does mean additional leads are needed. There are, however, two flies in the ointment, neither are showstoppers but make the board a little more difficult to use.

Orange Pi in my case with heatsinkOne is a simple necessity of a substantial heatsink on the H3 processor. Initially I used a small 20 x 20mm copper heatsink (around 800mm square surface area) but this was insufficient under full load. I did not want to have to use a fan so I milled some slots into copper round bar, then cut off sections and faced them on a lathe. The completed design had more than 2200 square mm surface area and cost around $2.5 ( 1.5) in material (and a couple of hours in the workshop but that was fun and I made something)

The second issue and arguably much more serious is that of software. Let me be honest, it is dreadful, I mean very bad indeed. The images provided from the Orange Pi website are some of the worst examples of "do something quick" I have experienced.

Fortunately a user on the forums named loboris decided to create scripts that generate a Debian (and Ubuntu and Fedora) distribution images that can be installed from SD card. He relies on a somewhat patched 3.4 kernel full of Allwinner vendor changes and the inevitable binary blobs for the Marli GPU but the result does work.

I have had a few units acting as distcc compiler slaves for two weeks now at 100% CPU loading and they are still running. The processor does not get overly warm with the heatsink installed and Debian behaves just fine. The main caveat being that it is definitely not going to work if you try and update the kernel through packaging.

My ARM build farm as a pile of SBC
The state of software support and Xunlong Software relying on a forum user to complete their product does tarnish an otherwise impressive and possibly market changing SBC.

Perhaps I expect too much for fifteen bucks? I guess when the cost of the case, heatsink, cables and memory storage card is similar to the rest of the computer there is simply no margin left for anything else.

In conclusion hopefully this brief overview has provided some insight into what is available in this market and that the Raspberry Pi is indeed not the only option.

I finish with an image is of my ARM build farm consisting of every SBC I mention here (including a couple of RPi)

Jonathan Dowland: Ikiwiki-in-a-box Docker container

For a while I've been wanting to tidy up some of my existing ikiwiki hacks, as well as test some changes I'd like to make to this site, but I hadn't had much success with setting up environments to play with it. That was until earlier in the year, when as a bit of an experiment I tried to put ikiwiki in docker. I've put up a preliminary image for anyone who is curious. It's in a very early state. When you start up the image, you get a HTTP daemon listening on port 8080 and serving a basic ikiwiki from /. A single administrative user is defined, user admin and password password. The CGI is set up (path /cgi) and websetup is enabled. The ikiwiki instance is configured with git as the vcs backend and the git HTTP backend is also enabled at path /git. It is set up for anonymous pull and HTTP basic authentication for push, with admin/password. There's still a lot to do before this is useful for what I want to do with it, and I would strongly advise against using it for anything except testing yourself, unless you are going to layer on some changes (HTTPS and change the credentials at the very least!) but I thought I'd put it out there. If you have any suggestions for it, please either file an issue or leave a comment here. It's built on top of the stuff I mentioned last time but it should rebase on top of the "semi-official" Debian images without problems.

Rapha&#235;l Hertzog: Freexian s report about Debian Long Term Support, September 2015

A Debian LTS logoLike each month, here comes a report about the work of paid contributors to Debian LTS. Individual reports In September, 71.50 work hours have been dispatched among 7 paid contributors. Their reports are available: Evolution of the situation October is back to the highest level of funding with 85.5 hours funded. The late sponsors have all caught up now. And next month will again rise to a new record with multiple sponsors having joined up. So far we already have two new silver sponsors (Universit Jean Monnet de Saint- tienne and Univention GmbH) and a new bronze sponsor (Entr ouvert). Many thanks to them! With those sponsors we crossed the 50% mark that was our first objective. \o/ But we still need more support to reach our second goal of funding the equivalent of a full time position. That said the increased level of support already allows us to do a better job in some areas that have been neglected : I asked the paid contributors to work towards providing mysql-5.5 in squeeze since version 5.1 is no longer supported by Oracle. We need beta testers to test the upgrade, see this message on the mailling list. In terms of security updates waiting to be handled, the situation is close to last month: the dla-needed.txt file lists 15 packages awaiting an update (3 less than last month), the list of open vulnerabilities in Squeeze shows about 23 affected packages in total (7 less than last month). Thanks to our sponsors The new sponsors are in bold.

Daniel Pocock: Enterprise-grade SIP coming to Telepathy

I've just announced the reSIProcate connection manager for the Telepathy framework on the Linux desktop. As the announcement states, it is still a proof-of-concept. It was put together very rapidly just to see how well the reSIProcate project and its build system interacts with TelepathyQt, the Qt framework and DBus. That said, I've been able to make calls from GNOME Empathy to Jitsi, Lumicall and Asterisk. Why this is important Telepathy is the default communications framework installed on many Linux desktops. Yet none of the standard connection managers offers thorough support for NAT traversal. NAT traversal is essential for calling people who are not on the same LAN, whether it is just making a call across town or across the world. The XMPP connection manager offers limited support for NAT traversal if one party in the call is using a Google account, but with Google deprecating XMPP support and not everybody wanting to use Google anyway, that is not a stable foundation for free operating systems. The reSIProcate solution TURN is the standard (RFC 5766) for relaying media streams when two users want to communicate across the boundaries of NAT networks. There are several TURN servers packaged on Linux now. TURN has also been adopted for WebRTC, so it is a good foundation to build on. reSIProcate's reCon library provides a high-level telephony API supporting TURN as well as DTLS-SRTP encryption and many other enterprise-grade features. It also has thorough support for things like DNS NAPTR and SRV records, so you can just put in your SIP address and password and it can discover the correct SIP server, port number and transport protocol from DNS queries. This helps solve another common problem, the complexity of configuring some other softphones. Screenshots A SIP buddy list isn't supported yet: We have to use the Empathy menu to start calls (New Call...) or access account settings: The account settings are very simple. Everything can be discovered using NAPTR and SRV queries, saving the user typing. For now, the TURN server is entered manually but that can also be discovered using an SRV query. Placing a call from my fedrtc.org Fedora SIP account to my debian.org SIP account: Project status and direction More work is required to make this connection manager fully functional. It is available now for testing against other products and to get feedback about how the design should evolve.

Norbert Preining: Debian/TeX Live multiarch update

A big update of all related packages (tex-common 6.04, texlive-bin 2015.20150524.37493-7, texlive-base/lang/extra package 2015.20151016-1) due to the move to support multi-arch. Of course, the regular updates of the TeX Live are included, too. With this change it should be possible to run a multi-arch system with only one TeX Live installed. Debian - TeX Live 2015 Thanks to the excellent support and testing of the Multi-arch guys, in particular Thorsten Glaser, Helmut Grohne, Johannes Schauer, and Wookey, I learned a lot about multi-arch, and I hope that the current setup is safe. All the packages but the various lib* packages are tagged as Multi-Arch: foreign, while the lib packages are tagged Multi-Arch: same. Anyway, if you find a bug concerning multi-arch, that is that some of the programs exhibit architecture information, please let us know via a bug report. Updated packages acro, alegreya, amiri, assoccnt, attachfile, babel-french, babel-hungarian, barr, beebe, biblatex-philosophy, bidi, bnumexpr, caption, chemfig, chemformula, chemmacros, cjk-gs-integrate, csplain, dantelogo, dataref, dtxgen, dvipdfmx-def, dvips, eledmac, elements, fcolumn, fithesis, fontspec, genealogytree, gradstudentresume, gtl, jfontmaps, knuth-local, koma-script, kotex-oblivoir, kotex-plain, kotex-utf, kpathsea, l3build, l3experimental, l3kernel, l3packages, latex, latexconfig, ledmac, ltxfileinfo, lualatex-math, luamplib, luatex, luatexbase, luatexja, luatexko, make4ht, mcf2graph, mflogo, modiagram, multiexpand, newtx, odsfile, old-arrows, paracol, pdfpages, pdftex, plain, pst-stru, pxchfon, randomwalk, reledmac, resumecls, rubik, selnolig, showhyphens, siunitx, suftesi, tetex, teubner, tex4ebook, tex4ht, texlive-scripts, tikzsymbols, tipfr, tools, tudscr, uassign, unicode-math, unravel, visualfaq, xepersian, xetex-def, xint.

Russ Allbery: Review: Ancillary Mercy

Review: Ancillary Mercy, by Ann Leckie
Series: Imperial Radch #3
Publisher: Orbit
Copyright: October 2015
ISBN: 0-316-24668-9
Format: Trade paperback
Pages: 330
This is the third book of the series that starts with Ancillary Justice. Please don't read it out of order. The three books form a rare thing in SF: a trilogy with a clear start and a clear ending. They're ideally read fairly close together so that you can remember the people involved. By the end of Ancillary Sword, Leckie had apparently resolved most of the plot in the Athoek system, although the Ghost Gate and broader imperial turmoil still lurked. I was expecting this novel to be another change of scene, and probably a broadening of the scope into the more sweeping events set off by earlier books. That's not what Ancillary Mercy is at all. Leckie caught me by surprise early, and the book kept not going in the direction I was expecting. And the result is brilliant. It's obviously difficult to talk about this in detail, since there's no way I'm going to spoil this or any of the previous books. This is some of the best SF I've ever read, and I want anyone who's not read the series yet to have the full experience. What I will say is that there was a lot of character growth left, including in some places that I thought would remain setting-mandated blind spots. Leckie tackles some very tricky themes, ones that are hard to do well because of how thoroughly the ground has already been explored, and still manages to find an original take and an even more original tone. And remains true to Breq's characterization throughout, including one critical scene that's masterful in its heart-breaking understatedness. Breq's flat affect is both very difficult and incredibly rewarding as a first-person protagonist. If I had to call out one thing that makes this series so special to me, it's the way that Leckie puts the reader in the middle of a restrained and very careful culture, centers the book on a character with a very unusual relationship to emotion, nearly completely avoids outward displays of feeling, treats emotions primarily as data to be weighed with other information, and yet provides just the right amount of subtle clues and external reflection to show just how central emotion is to everything that happens. This is an incredibly difficult balancing act, much harder than an openly emotional book (let alone the tough-guy cliches that military SF is normally full of), and it makes the occasional pay-offs so rewarding. I think some people might find Ancillary Mercy too understated, but I thought it was note-perfect throughout. And the ending was spectacular. For those who are less enamored of Breq and more interested in the plot, don't worry: we do get some resolution to most of the loose threads. There's clearly potential in this universe for more stories (and apparently more books coming!), but this trilogy comes to a definite end. If I had to quibble, I'd say that a few bits of the plot are too convenient: the resolution would have been impossible without one very critical mistake at the start of the second book, and there's at least one perfectly-timed accident. But Leckie's most critical plot resolution tool was properly hung on the wall in the last book and used perfectly. It's hard to manage a satisfying resolution to a twisty political conflict between very sharp antagonists; for me, at least, Leckie pulls it off. Looking back on the whole series, I find it striking how much more satisfying and believable Leckie's military culture is for her setting than those I normally read. I think we're too often given far-future military stories that are full of impulsive drama, high emotion, and physical feats. But in a world of starships and space stations, advanced computers, careful and systematized roles, and precise engineering, that's not realistic. While there is some physical violence required, problems in that world are more likely to look like operational computer problems than gladiatorial problems. That means the required tools are careful and fast analytical skills, quick iterative decision-making, and precise execution, not physical toughness and grit. In that world, adrenaline is at best useless and often your enemy. Leckie's world of tea sets and emotional control is partly driven by other world-building factors, but, particularly in this book, I was struck by how well-adapted it is to a military where calm decisions and efficient follow-through are far more important than adrenaline-driven courage. The emotion is absolutely there, but the catharsis doesn't come through bloody battles or feats of physicality. Again, so tricky to pull off, since it plays against the expectations we bring as readers to a war story, but I found it so much more satisfying when written well. I also love that this series is not about saving the world, at least in any direct sense. It is about justice, and ethics, and about standing up for what's right, but it's just as much about identity, about how to choose and define one's ethics, and how to make the most of the small number of decisions one gets to make. Everyone in this world is operating under sharp constraints: culture, ability, available alliances, physical limitations, and particularly the role into which they were cast. Huge things happen in this series, but not from the dramatic, order-overturning action of Chosen Ones. Rather, change is created by individuals who find small points of leverage and definition, and who make quiet, critical decisions to become better people than they were. I adore this series, and particularly this conclusion, beyond all rational measure. I'm sure that won't be universal, just as other readers weren't as enamored as I was of the direction Leckie went in Ancillary Sword. But this was a series conclusion that I was not expecting at all, that kept surprising me right up to the climax, and was exactly the conclusion that I wanted. If you liked the previous books, and particularly if you liked Ancillary Sword but thought Breq was a bit too much in control of the plot and a bit too able to make things go her way, I think you'll love Ancillary Mercy. This is simply the best SF series I've read in a long time. Rating: 10 out of 10

Laura Arjona: Long summer story, Welcome team, and I am a Debian Developer now

Note: 2015/10/16: I need to add some links but I won t delay this more, posting now, will edit later. Summer ended long time ago, but believe me, I m still catching up with all the things that I began in June/July, all the things I left in August when I went holidays, and more things that appeared in August and September. This is a long overdue post, I hope you bear with me for waiting so long, and writing (now) so long too! June In June, I was 100% sure that I would not attend DebConf15 (well, I was 98% sure until then), and when the new Outreach Sponsorship grants were announced, I decided to write some mails to several Debian contributors, so they consider applying for the grant and attend DebConf (and maybe trigger some i18n/l10n meeting ). They kindly declined, and I understood their reasons, but also wondered what would have happened if the proposal would have come from somebody more official instead of a random contributor that they don t know. I also hoped that lots of other Debianites also write to newbies or not-yet-DD-contributors or non-packaging contributors to invite them to DebConf, and I hoped that they had better luck than me in convincing them :) July In July I usually work hard preparing the computer labs for next academic year at my workplace in the University, but I also have more free time in the long afternoons and evenings, since I don t sleep much, and there is not much to do outside with the summer hot. So I used that month to go on contributing to DebConf publicity and think a bit more about Debian and the other free software communities. I didn t put much time in advancing my selfhosting (no SSL yet in *.larjona.net! booooo!) but I decided to deep my toe in Sandstorm.io, and try to selfhost an instance ( http://lacaja.larjona.net ) and try Etherpad inside Sandstorm (since I failed in deploying Etherpad by myself in my jessie+nginx+postgres box). Sandstorm worked, and Etherpad was packaged in Sandstorm so it worked too; and I have my free-software-base pads now for writing and share. So I joined #sandstorm IRC channel since then, and there I learnt that Asheesh Laroia (who works in Sandstorm.io and is also a Debian Developer and was going to give a talk about Sandstorm.io in DebConf15) was offering mentorship for people wanting to learn Sandstorm packaging, and his proposal was to begin packaging Framadate. I also failed in selfhosting Dudle (prepared for Apache + FastCGI, couldn t make it work in my Nginx), so Asheesh s proposal looked suitable for me. We talked and decided to invest the rest of July and first days of August in learning to package Framadate. I learned a lot, but couldn t finish the task. I encountered many issues (setting my dev environment, and later trying to package), and we solved some of them but my time ran out. I posted my work in the list, and I hope that my feedback on the documentation and the issues I encountered helped Asheesh and the Sandstorm community. Framadate is packaged in Sandstorm.io now, Drew Fisher packaged it, not sure if my stuff was useful or not (it s been useful for me, for learning, at least). I ll talk more about Sandstorm.io in a future blog post updating on my selfhosting adventures. What I liked most was the kind of proposal of mentoring that Asheesh made. It was very detailed in every aspect: the task, the things you need to accomplish it, details about his availability for mentorship I try to be welcoming in the teams in which I participate, but the fact is that I fail in actually mentor, maybe because of not making specific proposals to people (until now, I was like Hi, newcomer! Go read this, this and this, and try for yourself any task you feel you like it, and come back if you have issues , la Debian ). This, plus the thoughts about my mails in June for diversity outreach in DebConf, made me feel the need of having a team where people willing to welcome newcomers share tricks and procedures, write together more specific proposals, and follow up the newcomers experiences in a regular way. I talked with Enrico Zini and we wrote down some notes for a Welcome Team in Debian; he said he would spread the word during DebCamp/DebConf and we would see what people thinks about it. August August came, and the day before going on holidays I was really tired: too much luggage to prepare, too many hours in front of the computer, and the usual stress of traveling; and I took the bad decision of signing some GPG keys of several Debianites that I met in July. I say bad decision because the lack of sleep showed its black magic and I accidentally deleted my secring.gpg file. I knew I had a backup but I didn t have too much time to invest and I didn t want to mess it with the backup too, and my laptop was going to stay at home, powered off, during the whole month, so I just went on holidays and left the GPG issue for later. The day after, meanwhile I was waiting in the airport for my boarding time, I received a mail accepting me as Debian Developer. Wow!! Really, I was not expecting that the process was already finished, I had interchanged several mails with my Application Manager (who happens to be the current DPL!) and I thought that his summer could be quite packed of Debian/DebConf work and my process could wait a bit. So it was a very happy news and very motivating after one month (July) full of free software work. On the other side, I was a bit scared: what type of Debian Developer are you, larjona, not capable to sign some GPG keys without breaking your setup?! but I answered myself well, I m the type of Debian Developer that has backups :) and then, with that mixed feelings of excitement and impostor syndrome, I took my plane and went on holidays, not expecting to touch any computer until the end of the month. August is probably the month in the year when I have more free time (holidays), but less time to dedicate to free software. I devote most of the month to visit family and stay with them, with no internet connection available or no free time to look at the mailbox or social networks or IRC But DebCamp and DebConf15 were happening during my holidays. And this DebConf15 was the first one in which I participated in the organization, and the first one in which I felt more than being a consumer of Debian videos . I could not follow the streamings, my only internet-capable device was my Android 2.x phone, but when I had wifi I fetched the mail, and during the nights, while everybody else was sleeping and I was laying on the terrace, below the sky full of stars, I could read batches of hundred of mails from debconf-discuss mailing list. And I could get some feeling from DebConf life, because I learned about the ad-hoc BoFs and discussions, the morning bike rides and swimming proposals, and the dancing classes, the i18m/l10n meeting, and many other things. I could answer some mail from time to time, and I also knew that a fellow Debianite from Madrid was going to bring me some stickers, maybe a t-shirt, and shake hands in my name to some persons. September and October September was about finishing reading all the mails and try to answer the pending ones, and preparing my computer to use my new Debian identity (and stop using larjona-guest). I still have some things to do, pending technical work, and some mails that I should have answered and I ve forgotten, for sure (if you sent me a mail that needs answer or would be fine that I answer (even if it was months ago!), please resend or ping me). I recovered my secring.gpg but and just now I added larjona@debian.org to the ID in my GPG key, but didn t signed the pending keys again (sorry dkg and holger! will catch up there soon). My subkeys expired and I m trying to find out how to proceed (they are in my FSFE SmartCard) :/ About the Debian teams, I ve resumed my work in publicity team (this year I ll try to be more involved, in Debian Project News in particular), partially in the website team, and recently I ve finished catching up with the Spanish translation of the website. I ve also joined the DebConf team again (for DebConf16, no matter I probably won t attend) and documented the Publicity task for DebConf, and I try to engage the mailing list and the IRC meetings. I finally could have time to watch some DebConf15 videos and Andreas Tille s talk ( Creating a more inviting environment for newcomers New experiences from MoM, SoB, Teammetrics ) helped me to step ahead in welcoming people with more useful stuff than Hi, newcomer! Go read this (general URLs), try for yourself whatever you like . I have made specific proposals for two people. In mid September I accepted an interview about Debian for a podcast with quite a lot audience (in Spanish), in which I explained the idea of the Welcome Team and offered myself as first-contact. Since then, two more people have contacted me and I have offered specific tasks I think are suitable for them. I also try to be more available in the IRC and offer some time spans for new contributors to DebConf to explain the git setup, the wiki, and all this stuff that looks more complicated than what it is. And I think that s all. My Debianite friend kindly brought me some stickers and a DebConf t-shirt, plus the organization t-shirt that the team gave me as present for my contributions in DebConf15. Neil McGovern kindly sent me a certificate of my new Debian Developer status (thanks!!), and it s posted in my wall at work. Here you are a photo! larjona_dd.JPG (Note: my wall is full of stickers and pieces of papers with things I need, things I like and things I use to explain my work (sometimes sarcastically/ironically ). Maybe some day I ll make a blog post about that!) I feel very proud and happy. Still, a lot of things to learn and work to do, but my intentions are: to keep on progressing (sometimes fast, sometimes slowly), never give up, and enjoy the multiple flowers I find in my way :) Thanks everybody! October and future Some other ideas/plans for the future (the ones I didn t say yet): Comments? If you want to comment you can use this pump.io thread.
