There have been a two long threads on the debian-devel mailing list
about the representation of the changes to upstream source code made
by Debian maintainers. Here are a few notes for my own reference.
I spent a lot of time defending the workflow I described in
dgit-maint-merge(7) (which was inspired by this blog post).
However, I came to be convinced that there is a case for a manually
curated series of patches for certain classes of package. It will
depend on how upstream uses git (rebasing or merging) and on whether
the Debian delta from upstream is significant and/or long-standing. I
still think that we should be using dgit-maint-merge(7) for leaf or
near-leaf packages, because it saves so much volunteer time that can
be better spent on other things.
When upstream does use a merging workflow, one advantage of the
dgit-maint-merge(7) workflow is that Debian s packaging is just
another branch of development.
Now consider packages where we do want a manually curated patch
series. It is very hard to represent such a series in git. The only
natural way to do it is to continually rebase the patch series against
an upstream branch, but public branches that get rebased are not a
good idea. The solution that many people have adopted is to represent
their patch series as a folder full of .diff files, and then use
gbp pq to convert this into a rebasing branch. This branch is not
shared. It is edited, rebased, and then converted back to the folder
of .diff files, the changes to which are then committed to git.
One of the advantages of dgit is that there now exists an official,
non-rebasing git history of uploads to the archive.
It would be nice if we could represent curated patch series as
branches in the dgit repos, rather than as folders full of .diff
files. But as I just described, this is very hard. However, Ian
Jackson has the beginnings of a workflow that just might
fit the bill.
This is an extension to last month s article/sharing where I had shared the changes that had transpired in the last 2-3 months. Now am in a position to share the kind of issues a user can go through in case he is looking for support from IRCTC to help him/her go cashless. If you a new user to use IRCTC services you wouldn t go through this trouble.
For those who might have TL;DR issues it s about how hard it can become to get digital credentials fixed in IRCTC (Indian Railway Catering and Tourism Corporation)
a. 2 months back Indian Prime Minister gave a call incentivizing people to use digital means to do any commercial activities. One of the big organizations which took/takes part is IRCTC which handles the responsibility for e-ticketing millions of Rail tickets for common people. In India, a massive percentage moves by train as it s cheaper than going by Air.
A typical fare from say Pune Delhi (capital of India) by second class sleeper would be INR 645/- for a distance of roughly 1600 odd kms and these are monopoly rates, there are no private trains and I m not suggesting anything of that sort, just making sure that people know.
An economy class ticket by Air for the same distance would be anywhere between INR 2500-3500/- for a 2 hour flight between different airlines. Last I checked there are around 8 mainstream airlines including flag-carrier Air India.
About 30% of the population live on less than a dollar and a half a day which would come around INR 100/-.
There was a comment some six months back on getting more people out of the poverty line. But as there are lots of manipulations in numbers for who and what denotes above poor and below poor in India and lot of it has to do with politics it s not something which would be easily fixable.
There are lots to be said in that arena but this article is not an appropriate blog-post for that.
All in all, it s only 3-5% of the population at the most who can travel via Air if situation demands and around 1-2% who might be frequent, business or leisure travellers.
Now while I can thankfully afford an Air Ticket if the situation so demands, my mother gets motion sickness so while together we can only travel by train.
b. With the above background, I had registered with IRCTC few years ago with another number (dual-SIM) I had purchased and was thinking that I would be using this long-term (seems to my first big mistake, hindsight 50:50) . This was somewhere in 2006/2007.
c. Few months later I found that the other service provider wasn t giving good service or was not upto mark. I was using IDEA (the main mobile operator) throughout those times.
d. As I didn t need the service that much, didn t think to inform them that I want to change to another service provider at that point in time (possibly the biggest mistake, hindsight 50:50)
e. In July 2016 itself IRCTC cut service fees,
f. This was shared as a NEW news item/policy decision at November-end 2016 .
g. While I have done all that has been asked by irctc-care haven t still got the issues resolved 
IRCTC s e-mail id care@irctc.co.in
Now in detail
This is my first e-mail sent to IRCTC in June 2016
Dear Customer care, I had applied and got username and password sometime back . TheThere was lot of back and forth with various individuals on IRCTC and after a lot of back and forth, this is the final e-mail I got from them somewhere in August 2016, he writes
number I had used to register with IRCTC was xxxxxxxxxx (BSNL mobile number not used anymore) . My mobile was lost and along with that the number was also lost. I had filed a complaint with the police and stopped that number as well. Now I have an another mobile number but have forgotten both the password and the security answer that I had given when I had registered . I do have all the conversations I had both with the ticketadmn@irctc.co.in as well as care@irctc.co.in if needed to prove my identity. The new number I want to tie it with is xxxxxxxxxx (IDEA number in-use for last 10 years) I see two options :- a. Tie the other number with my e-mail address b. Take out the e-mail address from the database so that I can fill in
as a new applicant. Looking forward to hear from you.
Dear Customer, We request you to send mobile bill of your mobile number if it is post paid or if it is prepaid then contact to your service provider and they will give you valid proof of your mobile number or they will give you in written on company head letter so that we may update your mobile number to update so that you may reset your password through mobile OTP.IRCTC s response seemed responsible, valid and thought it would be a cake-walk as private providers are supposed to be much more efficient than public ones. The experience proved how wrong was I trust them with doing the right thing 1. First I tried the twitter handle to see how IDEA uses their twitter handle. 2. The idea customer care twitter handle was mild in its response. 3. After sometime I realized that the only way out of this quagmire would perhaps be to go to a brick-mortar shop and get it resolved face-to-face. I went twice or thrice but each time something or the other would happen. On the fourth and final time, I was able to get to the big Official shop only to be told they can t do anything about this and I would have to the appellate body to get the reply. The e-mail address which they shared (and I found it later) was wrong. I sent a somewhat longish e-mail sharing all the details and got bounce-backs. The correct e-mail address for the IDEA Maharashtra appellate body is appellette.mh@idea.aditybirla.com I searched online and after a bit of hit and miss finally got the relevant address. Then finally on 30th December, 2016 wrote a short email to the service provider as follows
and Kindly inform you that you can update your profile by yourself also. 1.login on IRCTC website

Dear Sir,Few days later I got this short e-mail from them
I have been using prepaid mobile connection number xxxxxxx taken from IDEA for last 10 odd years. I want to register myself with IRCTC for online railway booking using
my IDEA mobile number. Earlier, I was having a BSNL connection which I discontinued 4 years back, For re-registering myself with IRCTC, I have to fulfill their latest
requirements as shown in the email below . It is requested that I please be issued a letter confirming my
credentials with your esteemed firm. I contacted your local office at corner of Law College Road and
Bhandarkar Road, Pune (reference number Q1 84786060793) who
refused to provide me any letter and have advised me to contact on the
above e-mail address, hence this request is being forwarded to you. Please do the needful at your earliest.
Dear Customer, Greetings for the day! This is with reference to your email regarding services. Please accept our apologies for the inconvenience caused to you and delay in response. We regret to inform you that we are unable to provide demographic details from our end as provision for same is not available with us. Should you need any further assistance, please call our Customer Service help line number 9822012345 or email us at customercare@idea.adityabirla.com by mentioning ten digit Idea mobile number in subject line. Thanks & Regards, Javed Khan Customer Service Team IDEA Cellular Limited- Maharashtra & Goa Circle.Now I was at almost my wit s end. Few days before, I had re-affirmed my e-mail address to IDEA . I went to the IDEA care site, registered with my credentials. While the https connection to the page is weak, but let s not dwell on that atm. I logged into the site, I went through all the drop-down menus and came across My Account > Raise a request link which I clicked on . This came to a page where I could raise requests for various things. One of the options given there was Bill Delivery. As I wasn t a postpaid user but a prepaid user didn t know if that would work or not I still clicked on it. It said it would take 4 days for that to happen. I absently filed it away as I was somewhat sure that nothing would happen from my previous experience with IDEA. But this time the IDEA support staff came through and shared a toll-free SMS number and message format that I could use to generate call details from the last 6 months. The toll-free number from IDEA is 12345 and the message format is EBILL MON (short-form for month so if it s January would be jan, so on and so forth). After gathering all the required credentials, sent my last mail to IRCTC about a week, 10 days back
Dear Mr. Parivesh Patel, I was out-of-town and couldn t do the needful so sorry for the delay.Haven t heard anything them from them, apart from a generated token number, each time you send a reply happens. This time it was #4763548 The whole sequence of events throws a lot of troubling questions a. Could IRCTC done a better job of articulating their need to me instead of the run-around I was given ? b. Shouldn t there be a time limit to accounts from which no transactions have been done ? I hadn t done a single transaction since registering. When cell service providers including BSNL takes number out after a year of not using a number, why is that account active for so long ? c. As that account didn t have OTP at registration, dunno if it s being used for illegal activities or something. Update This doesn t seem to be a unique thing at all. Just sampling some of the tweets by people at @IRCTC_LTD https://twitter.com/praveen4al/status/775614978258718721 https://twitter.com/vis_nov25/status/786062572390932480 https://twitter.com/ShubhamDevadiya/status/794241443950948352 https://twitter.com/rajeshhindustan/status/798028633759584256 https://twitter.com/ameetsangita/status/810081624343908352 https://twitter.com/grkisback/status/813733835213078528 https://twitter.com/gbalaji_/status/804230235625394177 https://twitter.com/chandhu_nr/status/800675627384721409 , all of this just goes to show how un-unique the situation really is.
Now that I m back in town, I have been able to put together my prepaid
bills of last 6 months which should make it easy to establish my
identity. As had shared before, I don t remember my old password and the old
mobile number (BSNL number) is no longer accessible so can t go
through that route. Please let me know the next steps in correcting the existing IRCTC
account (which I haven t operated ever) so I can start using it to
book my tickets. Look forward to hearing from you.

Three packages are sent, and some times the packages do not follow the same path. This is shown for hop 5, where three different IP addresses replied to the traceroute request. There are many ways to measure trace routes. Other good traceroute implementations I use are traceroute (using ICMP packages) mtr (can do both ICMP, UDP and TCP) and scapy (python library with ICMP, UDP, TCP traceroute and a lot of other capabilities). All of them are easily available in Debian. This time around, I wanted to know the geographic location of different route points, to visualize how visiting a web page spread information about the visit to a lot of servers around the globe. The background is that a web site today often will ask the browser to get from many servers the parts (for example HTML, JSON, fonts, JavaScript, CSS, video) required to display the content. This will leak information about the visit to those controlling these servers and anyone able to peek at the data traffic passing by (like your ISP, the ISPs backbone provider, FRA, GCHQ, NSA and others). Lets pick an example, the Norwegian parliament web site www.stortinget.no. It is read daily by all members of parliament and their staff, as well as political journalists, activits and many other citizens of Norway. A visit to the www.stortinget.no web site will ask your browser to contact 8 other servers: ajax.googleapis.com, insights.hotjar.com, script.hotjar.com, static.hotjar.com, stats.g.doubleclick.net, www.google-analytics.com, www.googletagmanager.com and www.netigate.se. I extracted this by asking PhantomJS to visit the Stortinget web page and tell me all the URLs PhantomJS downloaded to render the page (in HAR format using their netsniff example. I am very grateful to Gorm for showing me how to do this). My goal is to visualize network traces to all IP addresses behind these DNS names, do show where visitors personal information is spread when visiting the page.
When I had a look around for options, I could not find any good
free software tools to do this, and decided I needed my own traceroute
wrapper outputting KML based on locations looked up using GeoIP. KML
is easy to work with and easy to generate, and understood by several
of the GIS tools I have available. I got good help from by NUUG
colleague Anders Einar with this, and the result can be seen in
my
kmltraceroute git repository. Unfortunately, the quality of the
free GeoIP databases I could find (and the for-pay databases my
friends had access to) is not up to the task. The IP addresses of
central Internet infrastructure would typically be placed near the
controlling companies main office, and not where the router is really
located, as you can see from the
KML file I created using the GeoLite City dataset from MaxMind.
I also had a look at the visual traceroute graph created by
the scrapy project,
showing IP network ownership (aka AS owner) for the IP address in
question.
The
graph display a lot of useful information about the traceroute in SVG
format, and give a good indication on who control the network
equipment involved, but it do not include geolocation. This graph
make it possible to see the information is made available at least for
UNINETT, Catchcom, Stortinget, Nordunet, Google, Amazon, Telia, Level
3 Communications and NetDNA.
In the process, I came across the
web service GeoTraceroute by
Salim Gasmi. Its methology of combining guesses based on DNS names,
various location databases and finally use latecy times to rule out
candidate locations seemed to do a very good job of guessing correct
geolocation. But it could only do one trace at the time, did not have
a sensor in Norway and did not make the geolocations easily available
for postprocessing. So I contacted the developer and asked if he
would be willing to share the code (he refused until he had time to
clean it up), but he was interested in providing the geolocations in a
machine readable format, and willing to set up a sensor in Norway. So
since yesterday, it is possible to run traces from Norway in this
service thanks to a sensor node set up by
the NUUG assosiation, and get the
trace in KML format for further processing.
Here we can see a lot of trafic passes Sweden on its way to
Denmark, Germany, Holland and Ireland. Plenty of places where the
Snowden confirmations verified the traffic is read by various actors
without your best interest as their top priority.
Combining KML files is trivial using a text editor, so I could loop
over all the hosts behind the urls imported by www.stortinget.no and
ask for the KML file from GeoTraceroute, and create a combined KML
file with all the traces (unfortunately only one of the IP addresses
behind the DNS name is traced this time. To get them all, one would
have to request traces using IP number instead of DNS names from
GeoTraceroute). That might be the next step in this project.
Armed with these tools, I find it a lot easier to figure out where
the IP traffic moves and who control the boxes involved in moving it.
And every time the link crosses for example the Swedish border, we can
be sure Swedish Signal Intelligence (FRA) is listening, as GCHQ do in
Britain and NSA in USA and cables around the globe. (Hm, what should
we tell them? :) Keep that in mind if you ever send anything
unencrypted over the Internet.
PS: KML files are drawn using
the KML viewer from Ivan
Rublev, as it was less cluttered than the local Linux application
Marble. There are heaps of other options too.
As usual, if you use Bitcoin and want to show your support of my
activities, please send Bitcoin donations to my address

Debian LTS
November marked the 20th month I contributed to Debian LTS
under the Freexian umbrella. I had 8 hours allocated which I used
by:
Welp I seem to have spent holidays of 1996 doing my first Debian package. The process of getting a package into Debian was quite straightforward then. "I have packaged fte, here is my pgp, can I has an account to upload stuff to Debian?" I think the bureaucracy took until second week of January until I could actually upload the created package.

A few months after joining, someone figured out that to pgp signatures to be useful, keys need to be cross-signed. Hence young me taking a long bus trip from countryside Finland to the capital Helsinki to meet the only other DD in Finland in a cafe. It would still take another two years until I met more Debian people, and it could be proven that I'm not just an alter ego of Lars ;) Much later an alternative process of phone-calling prospective DD's would be added.

A new version, now at 0.2.0, of RcppCCTZ is now on CRAN. And it brings a significant change: windows builds! Thanks to Dan Dillon who dug deep enough into the libc++ sources from LLVM to port the std::get_time() function that is missing from the 4.* series of g++. And with Rtools being fixed at g++-4.9.3 this was missing for us here. Now we can parse dates for use by RcppCCTZ on Windows as well. That is important not only for RcppCCTZ but also particularly for the one package (so far) depending on it: nanotime.
CCTZ is a C++ library for translating between absolute and civil times using the rules of a time zone. In fact, it is two libraries. One for dealing with civil time: human-readable dates and times, and one for converting between between absolute and civil times via time zones. It requires only a proper C++11 compiler and the standard IANA time zone data base which standard Unix, Linux, OS X, ... computers tend to have in /usr/share/zoneinfo -- and for which R on Windows ships its own copy we can use. RcppCCTZ connects this library to R by relying on Rcpp.
The RcppCCTZ page has a few usage examples, as does the post announcing the previous release.
The changes in this version are summarized here:
We also have a diff to the previous version thanks to CRANberries. More details are at the RcppCCTZ page; code, issue tickets etc at the GitHub repository.Changes in version 0.2.0 (2017-01-08)
- Windows compilation was enabled by defining
OFFSET()andABBR()for MinGW (#10 partially addressing #9)- Windows use completed with backport of
std::get_timefrom LLVM's libc++ to enablestrptimesemantics (Dan Dillon in #11 completing #9)- Timezone information on Windows is supplied via R's own copy of zoneinfo with
TZDIRset (also #10)- The interface to
formatDoublewas cleaned up

I use openssh every day, be it the ssh command for connecting to remote hosts, or the scp command for uploading/downloading files.
Once a day, or more, I forget that scp uses the non-obvious -P flag for specifying the port, not the -p flag that ssh uses.
Enough is enough. I shall not file a bug report against the Debian openssh-client page, because no doubt compatibility with both upstream, and other distributions, is important. But damnit I've had enough.
apt-get source openssh-client shows the appropriate code:
fflag = tflag = 0;

I reverse-engineered a video codec.

and offered help. Life is strange sometimes.)
I'd talk about this and some related stuff at FOSDEM, but there's a

Finding a Libc for tiny embedded ARM systems
You'd think this problem would have been solved a long time ago. All I
wanted was a C library to use in small embedded systems -- those with
a few kB of flash and even fewer kB of RAM.
Small system requirements
A small embedded system has a different balance of needs:

Today, Rcpp passed another milestone as 900 packages on CRAN now depend on it (as measured by Depends, Imports and LinkingTo declarations). The graph is on the left depicts the growth of Rcpp usage over time.
The easiest way to compute this is to use the reverse_dependencies_with_maintainers() function from a helper scripts file on CRAN. This still gets one or two false positives of packages declaring a dependency but not actually containing C++ code and the like. There is also a helper function revdep() in the devtools package but it includes Suggests: which does not firmly imply usage, and hence inflates the count. I have always opted for a tighter count with corrections.
Rcpp cleared 300 packages in November 2014. It passed 400 packages in June 2015 (when I only tweeted about it), 500 packages in late October 2015, 600 packages last March, 700 packages last July and 800 packages last October. The chart extends to the very beginning via manually compiled data from CRANberries and checked with crandb. The next part uses manually saved entries. The core (and by far largest) part of the data set was generated semi-automatically via a short script appending updates to a small file-based backend. A list of packages using Rcpp is kept on this page.
Also displayed in the graph is the relative proportion of CRAN packages using Rcpp. The four per-cent hurdle was cleared just before useR! 2014 where I showed a similar graph (as two distinct graphs) in my invited talk. We passed five percent in December of 2014, six percent July of last year, seven percent just before Christmas eight percent this summer, and nine percent mid-December.
900 user packages is a really large number. This puts more than some responsibility on us in the Rcpp team as we continue to keep Rcpp as performant and reliable as it has been.
At the rate things are going, the big 1000 may be hit some time in April.
And with that a very big Thank You! to all users and contributors of Rcpp for help, suggestions, bug reports, documentation or, of course, code.

I participated in Nanowrimo in November, but I failed to actually
finish the required 50,000 words during the month. Oh well. I plan on
finishing the book eventually, anyway.
Furthermore, as an open source exhibitionist I thought I'd publish
a chapter each month. This will put a bit of pressure on me to keep
writing, and hopefully I'll get some nice feedback too.
The working title is "Hacker Noir". I've put the first chapter up on
http://noir.liw.fi/.
So, once again I had a box that had been installed with the kind-of-wrong
Debian architecture, in this case, powerpc (32 bit, bigendian), while I
wanted ppc64 (64 bit, bigendian). So, crossgrade time.
If you want to follow this, be aware that I use sysvinit. I doubt this can
be done this way with systemd installed, because systemd has a lot more
dependencies for PID 1, and there is also a dbus daemon involved that
cannot be upgraded without a reboot.
To make this a bit more complicated, ppc64 is an unofficial port, so it is
even less synchronized across architectures than sid normally is (I would
have used jessie, but there is no jessie for ppc64).
Step 1: Be Prepared
To work around the archive synchronisation issues, I installed pbuilder and
created 32 and 64 bit base.tgz archives:
pbuilder --create --basetgz /var/cache/pbuilder/powerpc.tgz
pbuilder --create --basetgz /var/cache/pbuilder/ppc64.tgz \
--architecture ppc64 \
--mirror http://ftp.ports.debian.org/debian-ports \
--debootstrapopts --keyring=/usr/share/keyrings/debian-ports-archive-keyring.gpg \
--debootstrapopts --include=debian-ports-archive-keyring
sources.list, and added the architecture to dpkg:
deb [arch=powerpc] http://ftp.debian.org/debian sid main
deb [arch=ppc64] http://ftp.ports.debian.org/debian-ports sid main
deb-src http://ftp.debian.org/debian sid main
dpkg --add-architecture ppc64
apt update
apt install dpkg:ppc64
libattr1 and libacl1
weren't in sync, so there was no valid way to install powerpc and ppc64
versions in parallel, so I used pbuilder to compile the current version
from sid for the architecture that wasn't up to date (IIRC, one for
powerpc, and one for ppc64).
Manually installed the libraries, then tried again:
apt install dpkg:ppc64
dpkg twice, once to remove the old version, and once to install the
new one. Your options at this point are
apt-get download dpkg:ppc64
dpkg -i dpkg_*_ppc64.deb
cd /tmp
ar x /var/cache/apt/archives/dpkg_*_ppc64.deb
cd /
tar -xJf /tmp/data.tar.xz
dpkg -i /var/cache/apt/archives/dpkg_*_ppc64.deb
apt and aptitude and their dependencies. Thanks to
pbuilder, this wasn't too bad.
With the aptitude resolver, it was then simple to upgrade a test package
aptitude install coreutils:ppc64 coreutils:powerpc-
Essential package. I did, and it replaced the package just fine.
So I asked dpkg for a list of all powerpc packages installed (since it's
a ppc64 dpkg, it will report powerpc as foreign), massage that into
shape with grep and sed, and give the result to aptitude as a command
line.
Some time later, aptitude finished, and I had a shiny 64 bit system.
Crossgrade through an ssh session that remained open all the time, and
without a reboot. After closing the ssh session, the last 32 bit binary was
deleted as it was no longer in use.
There were a few minor hiccups during the process where dpkg refused to
overwrite "shared" files with different versions, but these could be solved
easily by manually installing the offending package with
dpkg --force-overwrite -i ...

This week I went ahead with the implementation by using productFlavors feature in Android. I baked my cake!
Next.
