Contemplate how close to the FSDG Debian might be and approaches to improving that.

Dimitri John Ledkov: Post-Brexit - The What Now?

26 June, 2016 - 02:24
Out of 46,500,001 electorate 17,410,742 voted to leave, which is a mere 37.4% or just over a third. [source]. On my books this is not a clear expression of the UK wishes.

The reaction that the results have caused are devastating. The Scottish First Minister has announced plans for 2nd Scottish Independence referendum [source]. Londoners are filing petitions calling for Independent London [source, source]. The Prime Minister announced his resignation [source]. Things are not stable.
I do not believe that super majority of the electorate are in favor of leaving the EU. I don't even believe that those who voted to leave have considered the break up of the UK as the inevitable outcome of the leave vote. There are numerous videos on the internet about that, impossible to quantify or reliably cite, but for example this [source]
So What Now?
P R O T E S T
I urge everyone to start protesting the outcome of the mistake that happened last Thursday. 4th of July is a good symbolic date to show your discontent with the UK governemnt and a tiny minority who are about to cause the country to fall apart with no other benefits. Please stand up and make yourself heard.
  • General Strikes 4th & 5th of July
There are 64,100,000 people living in the UK according to the World Bank, maybe the government should fear and listen to the unheard third. The current "majority" parliament was only elected by 24% of electorate.

It is time for people to actually take control, we can fix our parliament, we can stop austerity, we can prevent the break up of the UK, and we can stay in the EU. Over to you.

ps. How to elect next PM?

Electing next PM will be done within the Conservative Party, and that's kind of a bummer, given that the desperate state the country currently is in. It is not that hard to predict that Boris Johnson is a front-runner. If you wish to elect a different PM, I urge you to splash out 25 quid and register to be a member of the Conservative Party just for one year =) this way you will get a chance to directly elect the new Leader of the Conservative Party and thus the new Prime Minister. You can backdoor the Conservative election here.

Paul Wise: DebCamp16 day 1

25 June, 2016 - 00:46

Hating jetlag based headache. Disturbed to see the Brexit result. Review wiki RecentChanges. Answer some questions about Launchpad on #debian-mentors. Whitelisted one user in the wiki anti-spam system. Reviewed and sponsored yamllint 1.2.2-1 upload. Noted OFSET repo is broken and updated Freeduc info. Noted the Epidemic-Linux website is having database issues. Noted that Facebook finally completely dropped their RSS feeds, dropped Facebook RSS feed URL generation from the Debian derivatives census scripts and notified the affected derivatives. Cleared up Tanglu hash sum mismatches again. Minor changes to Planet Debian derivatives. Enjoyed the photos from Valessio. Hazy city away from the mountain and tablecloth clouds flowing over the mountain on the way to a pub lunch. Jet lag headaches seem to be subsiding thankfully. Ping someone generating a bounce when changing their SSH key. Mention autorevision and other suggestions in an IRC discussion about mesa & reproducible builds. Review some DebConf16 announcements and add minor fix. Push out some TODO items to check-all-the-things. Ask for a dd-list for the GCC 6 transition. Usual spam reporting throughout the day via manual List-Archive copy-paste, feeding mboxen to my report-spam-debian-lists and report-spam-debian-bugs scripts and manual BTS clicks. Usual wondering why there isn't an RFC for MUA spam reporting. Disturbed by the sudden appearance of an astronautess in the orga room but placated by a plentiful supply of crisps. Ask x32 folks about debian-x32.org vs x32 on ports.d.o. Glad to just avoid the room shuffle dance. Finish mime support for check-all-the-things. Disappointed that piz.za does not actually resolve. Amused by pollito's virtual tour of UTC. Completely stuffed full of Butleritos.

Joey Hess: twenty years of free software -- part 5 pristine-tar

24 June, 2016 - 20:38

I've written retrospectively about pristine-tar before, when I stopped maintaining it. So, I'll quote part of that here:

[...] a little bit about the reason I wrote pristine-tar in the
first place. There were two reasons:

1. I was once in a talk where someone mentioned that Ubuntu had/was
   developing something that involved regenerating orig tarballs
   from version control.
   I asked the obvious question: How could that possibly be done
   technically? 
   The (slightly hung over) presenter did not have a satesfactory
   response, so my curiosity was piqued to find a way to do it.
   (I later heard that Ubuntu has been using pristine-tar..)

2. Sometimes code can be subversive. It can change people's perspective
   on a topic, nudging discourse in a different direction. It can even
   point out absurdities in the way things are done. I may or may not
   have accomplished the subversive part of my goals with pristine-tar.

Code can also escape its original intention. Many current uses of
pristine-tar fall into that category. So it seems likely that some
people will want it to continue to work even if it's met the two goals
above already.

For me, the best part of building pristine-tar was finding an answer to the question "How could that possibly be done technically?" It was also pretty cool to be able to use every tarball in Debian as the test suite for pristine-tar.

I'm afraid I kind of left Debian in the lurch when I stopped maintaining pristine-tar.

"Debian has probably hundreds, if not thousands of git repositories using pristine-tar. We all rely now on an unmaintained, orphaned, and buggy piece of software." -- Norbert Preining

So I was relieved when it finally got a new maintainer just recently.

Still, I don't expect I'll ever use pristine-tar again. It's the only software I've built in the past ten years that I can say that about.

Paul Wise: DebCamp16 day 0

24 June, 2016 - 04:16

Today is officially the first day of DebCamp 2016. The night wasn't as cold as I had feared. Woke at 5am for some reason. Noted the network still blocks port 6697 and 7000, worked around in IRC client configuration using 9999. Reply to network discussion to point that out. Minor changes to the empathy Debian RTC wiki page. Answer support@mentors.d.n bug email about shared company OpenPGP keys and suggest moving to individual keys. Review wiki RecentChanges. Comment on NetworkManager upstream bug #705545 that MAC address privacy is a complicated feature with many use cases. Warn another person that reporting Alioth to SpamCop does nothing and link to the unsubscription URL. Talk to Brown about IP address conflict sparc64 porters found with the setup of notker (sparc64 build machine). Filed Debian wishlist bug #827944 against at asking for support for using an editor to write at jobs. Woke up properly, discussed spam over breakfast. Notice Point Linux in the Distrowatch feed and invite them to the derivatives census. Point out reproducible builds in a discussion about source-only uploads. Commented that I encountered evolution upstream crash bug #680471 again. Reported gnome-shell upstream crash bug #767969. Joined the tour around the campus, enjoyed the view from the outdoor hacklab at the top of the hill. Confirmed that "Monkey Gland" from the pub menu is not in fact derived from monkeys in any way. Noted that Pollito did not eat chicken from the buffet. Beat head against VPN/SIP/WebRTC for a while but oncoming jetlag put me out of business for some hours. Pointed out the future Packages.gz removal in favour of Packages.xz to the popcon developers.

Jaminy Prabaharan: GSoC-Journey till Mid term evaluation

23 June, 2016 - 22:04

Hi readers,

The bad habit I am having is that I don’t write whatever I do.But now I realised that it’s better to  write about what you did to keep the record of it.This is one of the thing I learnt from GSoC.Here comes my journey till the mid term evaluation (June 21st) as a blog to share my experience.

I  have previously worked on some social related projects such as “smart guidance for blind” and “sensor based wireless controller”. I have been selected as a speaker for FOSSASIA-16 (Asia’s premier technological event)to talk on the project “smart guidance for blind”.FOSSASIA speakers. It was a great experience participating in the technological event in Singapore science centre.Got an opportunity to meet open source contributors from all over the world(even though it is an Asian event, participation was all over from the world). There were pre-meetups for FOSSASIA on the day before three day event.I have attended the one organised by RedHat, Singapore.Discussed on many topics related to open source.

Three days of FOSSASIA event was a great experience.It was the second time as a speaker in an international conference.My talk was on the second day.Sharing is the best way to increase your knowledge. Talks and workshops were brainstorming.Learnt many new things and got the courage to contribute to the open source.Met Daniel Pocock in Debian exhibition table.Meeting awesome people can be the turning point of life.Had a discussion about the Debian projects and it motivated me for open source software.We have discussed about the Real Time Communication and was encouraged to apply for GSoC  (Google Summer of Code). As per our discussion, prepared the project proposal on “improving voice,video and chat communication with free software” and submitted it for GSoC. I have been selected to contribute for Debian with stipend from Google.

This was my first application for GSoC and I have been selected to contribute for open source and free software. I would like to thank Google and Debian for giving this amazing experience.

Learning and coding has begun.Updated my laptop with Jessie, latest version of Debian.Get acquainted with the new platform.Got to learn many things about Real Time Communication.Learnt more about SIP, XMPP, peer to peer technology to work on my project.It’s always better to be clear with theory before coding.When it comes to voice and video over IP, most people nowadays are quick to use Skype, Whatsapp, or Viber. My main goal of the project are helping people to avoid using proprietary communications tools like Skype, Viber and WhatsApp and simplifying the setup of free alternatives like Jitsi, Linphone, Ekiga, Tox (qtox), Mumble.Downloaded some of the already available open source VoIP to find the problems behind it.Bootstrapping any business relevant network based on these free alternatives is still hard.

Would you like to list the senders, receivers and date of the messages in the inbox  of your mail.Python has a library file IMAP which can be used to connect to an email account, examine every message in every folder and look at the “To”, “From” and “CC” headers of every email message in the folder.

Do you have phone numbers and other contact details in old emails? Would you like a quick way to data-mine your inbox to find them and help migrate them to your address book? Got the help from phonenumbers library for parsing, formatting, and validating international phone numbers.I would like to share how I imported this library file into my coding.Download the given library file and open the file in the terminal.Type $python setup.py to include the library file.Now you can call the functions by importing phonenumbers.

You can go through the code in my GitHub profile here

It was a wonderful journey till now.Will be working further to improve voice, video and chat communication with free software.Stay connected to know more about my  further journey through GSoC.


Jonathan McDowell: Fixing missing text in Firefox

23 June, 2016 - 21:23

Every now and again I get this problem where Firefox won’t render text correctly (on a Debian/stretch system). Most websites are fine, but the odd site just shows up with blanks where the text should be. Initially I thought it was NoScript, but turning that off didn’t help. Daniel Silverstone gave me a pointer today that the pages in question were using webfonts, and that provided enough information to dig deeper. The sites in question were using Cantarell, via:

src: local('Cantarell Regular'), local('Cantarell-Regular'), url(cantarell.woff2) format('woff2'), url(cantarell.woff) format('woff');

The Firefox web dev inspector didn’t show it trying to fetch the font remotely, so I removed the local() elements from the CSS. That fixed the page, letting me pinpoint the problem as a local font issue. I have fonts-cantarell installed so at first I tried to remove it, but that breaks gnome-core. So instead I did an fc-list | grep -i cant to ask fontconfig what it thought was happening. That gave:

/usr/share/fonts/opentype/cantarell/Cantarell-Regular.otf.dpkg-tmp: Cantarell:style=Regular
/usr/share/fonts/opentype/cantarell/Cantarell-Bold.otf.dpkg-tmp: Cantarell:style=Bold
/usr/share/fonts/opentype/cantarell/Cantarell-Bold.otf: Cantarell:style=Bold
/usr/share/fonts/opentype/cantarell/Cantarell-Oblique.otf: Cantarell:style=Oblique
/usr/share/fonts/opentype/cantarell/Cantarell-Regular.otf: Cantarell:style=Regular
/usr/share/fonts/opentype/cantarell/Cantarell-Bold-Oblique.otf: Cantarell:style=Bold-Oblique
/usr/share/fonts/opentype/cantarell/Cantarell-Oblique.otf.dpkg-tmp: Cantarell:style=Oblique
/usr/share/fonts/opentype/cantarell/Cantarell-BoldOblique.otf: Cantarell:style=BoldOblique

Hmmm. Those .dpkg-tmp files looked odd, and sure enough they didn’t actually exist. So I did a sudo fc-cache -f -v to force a rebuild of the font cache and restarted Firefox (it didn’t seem to work before doing so) and everything works fine now.

It seems that fc-cache must have been run at some point when dpkg had not yet completed installing an update to the fonts-cantarell package. That seems like a bug - fontconfig should probably ignore .dpkg* files, but equally I wouldn’t expect it to be run before dpkg had finished its unpacking stage fully.

Joey Hess: twenty years of free software -- part 4 ikiwiki-hosting

23 June, 2016 - 19:26

ikiwiki-hosting is a spin-off from ikiwiki. I wrote it to manage many ikiwiki instances for Branchable, and made it free software out of principle.

While Branchable has not reached the point of providing much income, it's still running after 6 years. Ikiwiki-hosting makes it pretty easy to maintain it, and I host all of my websites there.

A couple of other people have also found ikiwiki-hosting useful, which is not only nice, but led to some big improvements to it. Mostly though, releasing the software behind the business as free software caused us to avoid shortcuts and build things well.

#Randa2016 KDE Sprint

Debian:

I am very late on post due to travel, Flu, jetlag sorry!

choqok:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=825322
For this I was able to come up with a patch for kconfig_compiler to encode generated files to utf-8.
Review request is here:
https://git.reviewboard.kde.org/r/128102/
This has been approved and I will be pushing it as soon as I patch the qt5 frameworks version.

Both kde4libs and kf5 kconfig has been pushed upstream kde.

kxmlgui:

WIP this has been a steep learning curve, according to the notes it was an easy embedded kernel version, that was not the case! After grueling hours of
trying to sort out randomness in debug output I finally narrowed it down to cases where QStringLiteral was used and there were non letter characters eg. (” <") These were causing debug symbols to generate with ( lambda() ) which caused unreproducible symbol/debug files. It is now a case of fixing all of these in the code to use QString::fromUtf8 seems to fix this. I am working on a mega patch for upstream and it should be ready early in the week. This last week I spent a large portion making my through a mega patch for kxmlgui, when it was suggested to me to write a small qt app to test QStringLiteral isolated and sure enough two build were byte for byte identical. So this means that QStringLiteral may not be the issue at all. With some more assistance I am to expand my test app with several QStringLiterals of varying lengths, we have suspicion it is a padding issue, which complicates things.

I am still fighting with this one, will set aside to simmer for now, as I have no idea how to fix padding issues.

extra-cmake-modules:
I am testing a patch to fix umask issues for anyone that uses the kapptemplate generation macro. Thank you Simon for pointing me to this.
known affected:
plasma-framework

kdevplatform:
The kapptemplate generation users/groups and umask patch has been pushed upstream.
https://bugs.kde.org/show_bug.cgi?id=363615

KDE Randa!:
Despite managing to get a terrible Flu I accomplished more than I would have at home without awesome devs to help me out!

  • I have delegated the windows backend to Hannah and Kevin, if emerge is successful with Windows we will implement it on OSX as well.
  • Android docker image is up and running.
  • Several snappy packages done. Improved the snapcraft.yaml creation automation scripts started by Harald. Got help from
    David ( he even made a patch! ) with some issues we were facing with kio.
  • KDE CI DSL adjustments for 5 new platforms
  • Port tools/* python scripts to python3

CI TODO:

  • Python automation scripts can no longer find projects except qt5… Need to get help from Ben as these are originally his.
  • Finish yaml CI files

Randa as usual was an amazing experience. Yes it is very hard work, but you have the beauty of the Swiss Alps at your fingertips! Not to mention all the
friendly faces and collaboration. A big thank you to all supporters and the Randa team!

Please help make KDE better by supporting the very important Randa Sprint:
https://www.kde.org/fundraisers/randameetings2016/

Have a great day.

Paul Wise: DebCamp16 day -1

22 June, 2016 - 23:34

Landed late due to technical delays. Mountains! Mountains are everywhere! Beautiful sunny day with clear blue skies. Ran into Valessio as I was shown to my room. Wandered around the campus for a bunch of hours. Ate an all you can eat yum buffet lunch at the pub. Wandered down the hill and ended up on the train and wandering around a lake with lilies in a park. Arriving back at UCT we ran into a beer mission along with some wonderful arriving folks. The warm DebConf nervous centre was quite inviting and soon had plentiful beer, pizza and discussion.

Joey Hess: twenty years of free software -- part 3 myrepos

22 June, 2016 - 23:24

?myrepos is kind of just an elaborated foreach (@myrepos) loop, but its configuration and extension in a sort of hybrid between an .ini file and shell script is quite nice and plenty of other people have found it useful.

I had to write myrepos when I switched from subversion to git, because git's submodules are too limited to meet my needs, and I needed a tool to check out and update many repositories, not necessarily all using the same version control system.

It was called "mr" originally, but I renamed the package because it's impossible to google for "mr". This is the only software I've ever renamed.

Andrew Cater: "But I'm a commercial developer / a government employee"

22 June, 2016 - 22:48
Following on:

Having seen some posts about this elsewhere on the 'Net:

  • Your copyright remains your own unless you assign it
  • Establish what you are being paid for: are you being paid for :
  1. Your specific area of FLOSS expertise (or)
  2. Your time / hours in an area unrelated to your FLOSS expertise (or)
  3. A job that has no impact or bearing on your FLOSS expertise (or)
  4. Your time / hours only - and negotiate accordingly
Your employer may be willing to negotiate / grant you an opt-out clause to protect your FLOSS expertise /  accept an additional non-exclusive licence to your FLOSS code / be prepared to sign an assignment e.g.

"You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright
interest in the program `Gnomovision'
(which makes passes at compilers) written
by James Hacker.

signature of Ty Coon, 1 April 1989
Ty Coon, President of Vice"
 
[http://www.gnu.org/licenses/old-licenses/gpl-2.0.en.html

If none of the above is feasible: don't contribute anything that crosses the streams and mingles commercial and FLOSS expertise, however much you're offered to do so.

Patents / copyrights

"In the 1980s I had not yet realized how confusing it was to speak of “the issue” of “intellectual property”. That term is obviously biased; more subtle is the fact that it lumps together various disparate laws which raise very different issues. Nowadays I urge people to reject the term “intellectual property” entirely, lest it lead others to suppose that those laws form one coherent issue. The way to be clear is to discuss patents, copyrights, and trademarks separately. See further explanation of how this term spreads confusion and bias."
 [http://www.gnu.org/gnu/manifesto.en.html - footnote 8.]

If you want to assert a patent - it's probably not FLOSS. Go away :)

If you want to assert a trademark of your own - it's probably not FLOSS. Go away :)
 [Trademarks may ordinarily be outside the scope of normal FLOSS legal considerations - but should be acknowledged wherever they occur both as a matter of law and as a matter of courtesy]

Copyright gives legal standing (locus standi in the terminology of English common law) to sue for infringement - that's the basis of licence enforcement actions.

Employees of governments and those doing government work
  • Still have the right to own authorship and copyrights and to negotiate accordingly
  • May need to establish more clearly what they're being paid for
  • May be able to advise, influence or direct policy towards FLOSS in their own respective national jurisdiction
  • Should, ideally, be primariily acknowledged as individuals, holding and maintaining an individual reputation  and only secondarily as contractors/employees/others associated with government work.
  • Contribution to national / international standards, international agreements and shared working practices should be informed in the light of FLOSS work.
This is complex: some FLOSS contributors see a significant amount of this as immaterial to them in the same way that some indigenous populations do not acknowledge imposed colonial legal structures as valid - but both value systems can co-exist




Andrew Cater: How to share collaboratively

22 June, 2016 - 22:19
Following on:

When contributing to mailing lists and fora:
  • Contribute constructively - no one likes to be told "You've got a REALLY ugly baby there" or equivalent.
  • Think through what you post: check references and check that it reads clearly and is spelled correctly
  • Add value
 When contributing bug reports:
  •  Provide as full details of hardware and software as you have
  • Answer questions carefully: Ask questions the smart way: http://www.catb.org/esr/faqs/smart-questions.html
  • Be prepared to follow up queries / provide sufficient evidence to reproduce behaviour or provide pathological test cases 
  • Provide a patch if possible: even if it's only pseudocode
When adding to / modifying FLOSS software:
  • Keep pristine sources that you have downloaded
  • Maintain patch series against pristine source
  • Talk to the originators of the software / current maintainers elsewhere
  • Follow upstream style if feasible / a consistent house style if not
  • Be generous in what you accept: be precise in what you put out
  • Don't produce licence conflicts - check and check again that your software can be distributed.
  • Don't apply inconsistent copyrights
When writing new FLOSS software / "freeing" prior commercial/closed code under a FLOSS licence
  • Make permissions explicit and publish under a well established FLOSS licence 
  • Be generous to potential contributors and collaborators: render them every assistance so that they can help you better
  • Be generous in what you accept: be precise in what you put out
  • Don't produce licence conflicts - check and check again that your software can be distributed.
  • Don't apply inconsistent copyrights: software you write is your copyright at the outset until you assign it elsewhere
  • Contribute documentation / examples
  • Maintain a bugtracker and mailing lists for your software
If you are required to sign a contributor license agreement [CLA]
  • Ensure that you have the rights you purport to assign
  • Assign the minimum of rights necessary - if you can continue to allow full and free use of your code, do so
  • Meet any  required code of conduct [CoC] stipulations in addition to the CLA
Always remember in all of this: just because you understand your code and your working practices doesn't mean that anyone else will.
There is no automatic right to contribution nor any necessary assumption or precondition that collaborators will come forward.
Just because you love your own code doesn't mean that it merits anyone else's interest or that anyone else should value it thereby
"Just because it scratches your itch doesn't mean that it scratches anyone else's - or that it's actually any good / any use to anyone else"

So - collaboration matters. Not repeating needless make-work that someone else has already done matters. Giving due credit: sharing: doing and "do-ocracy" matters above all

Perversely, Acknowledging prior work and prior copyright correctly is the beginning and end of the law. Only by doing this conscientiously and sharing in giving due credit can any of us truly participate.

It seems clear to me at least that contributing openly and freely, allowing others to make use of your expertise, opinions, prior experience can anyone progress in good conscience.

Accordingly, I recommend to my work colleagues and those I advise that they only consider FLOSS licences, that they do not make use of code snippets or random, unlicensed code culled form Github and that they contribute








Satyam Zode: GSoC 2016 Week 4 and 5: Reproducible Builds in Debian

22 June, 2016 - 17:47

This is a brief report on my last week work with Debian Reproducible Builds.

In week 4, I mostly worked on designing an interfaces and tackling different issues related to argument completion feature of diffoscope and in week 5 I worked on adding hiding .buildinfo from .changes files.

Update for last week’s activities
  • I researched different diffoscope outputs. In reproducible-builds testing framework only differences of .buildinfo files are given but I needed diffoscope outputs for .changes files. Hence, I had to build packages locally using our experimental tool chain. My goal was to generate different outputs and to see how I can hide .buildinfo files from .changes.
  • I updated argument completion patch as per suggestions given by Paul Wise (pabs). Patch has been reviewed by Mattia Rizzolo, Holger Levsen and merged by Reiner Herrmann (deki) into diffoscope master. This patch closes #826711. Thanks all for support.

  • For Ignore .buildinfo files when comparing .changes files, we finally decided to enable this by default and without having any command line option to hide.

  • Last week I researched more on .changes and .buildinfo files. After getting guidelines from Lunar I was able to understand the need of this feature. I am in the middle of implementation of this particular problem.

Goal for upcoming week:
  • Finish the implementation of hiding .buildinfo from .changes
  • Start thinking on interfaces and discuss about different use cases.

I am thankful to Shirish Agarwal for helping me through visa process. But, unfortunately I won’t get visa till 5th July. So I don’t think, I would make it to debconf this year. I will certainly attend Debconf 2017. Good news for me is I have passed mid-term evaluations of Google Summer of Code 2016. I will continue my work to improve Debian. Even, I have post GSoC plans ready for Debian project ;)

Have a nice day :)

Andrew Cater: Why I must use Free Software - and why I tell others to do so

22 June, 2016 - 16:43
My work colleagues know me well as a Free/Libre software zealot, constantly pointing out to them how people should behave, how FLOSS software trumps commercial software and how this is the only way forward. This for the last 20 odd years. It's a strain to argue this repeatedly: at various times,  I have been asked to set out more clearly why I use FLOSS, what the advantages are, why and how to contribute to FLOSS software.

"We are creating a world that all may enter without privilege or prejudice accorded by race, economic power, military force, or station of birth.
We are creating a world where anyone, anywhere may express his or her beliefs, no matter how singular, without fear of being coerced into silence or conformity.
Your legal concepts of property, expression, identity, movement, and context do not apply to us. They are all based on matter, and there is no matter here
 ...
 In our world, whatever the human mind may create can be reproduced and distributed infinitely at no cost. The global conveyance of thought no longer requires your factories to accomplish."
[John Perry Barlow - Declaration of the independence of cyberspace  1996  https://www.eff.org/cyberspace-independence]

That's some of it right there: I was seduced by a modem and the opportunities it gave. I've lived in this world since 1994, come to appreciate it and never really had the occasion to regret it.

I'm involved in the Debian community - which is very much  a "do-ocracy"  - and I've lived with Debian GNU Linux since 1995 and not had much cause to regret that either, though I do regret that force of circumstance has meant that I can't contribute as much as I'd like. Pretty much every machine I touch ends up running Debian, one way or the other, or should do if I had my way.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
Digging through my emails since then on the various mailing lists - some of them are deeply technical, though fewer these days: some are Debian political: most are trying to help people with problems / report successes or, occasionally thanks and social chit chat. Most people in the project have never met me - though that's not unusual in an organisation with a thousand developers spread worldwide - and so the occasional chance to talk to people in real life is invaluable.

The crucial thing is that there is common purpose and common intelligence - however crazy mailing list flame wars can get sometimes - and committed, caring people. Some of us may be crazy zealots, some picky and argumentative - Debian is what we have in common, pretty much.

It doesn't depend on physical ability. Espy (Joel Klecker) was one of our best and brightest until his death at age 21: almost nobody knew he was dying until after his death. My own physical limitations are pretty much irrelevant provided I can type.

It does depend on collaboration and the strange, dysfunctional family that is our community and the wider FLOSS community in which we share and in which some of us have multiple identities in working with different projects.
This is going to end up too long for Planet Debian - I'll end this post here and then continue with some points on how to contribute and why employers should let their employers work on FLOSS.




Martin-&#201;ric Racine: Batch photo manipulation via free software tools?

22 June, 2016 - 15:12

I have a need for batch-processing pictures. My requirements are fairly simple:

  • Resize the image to fit Facebook's preferred 960 pixel box.
  • Insert Copyright, Byline and Bylinetitle into the EXIF data.
  • Optionally, paste my watermark onto a predefined corner of the image.
  • Optionally, adjust the white balance.
  • Rename the file according to a specific syntax.
  • Save the result to a predefined folder.

Until recently, I was using Phatch to perform all of this. Unfortunately, it cannot edit the EXIF data of my current Lumix camera, whose JPEG it claims to be MPO. I am thus forced to look for other options. Ideally, I would do this via a script inside gThumb (which is my main photo editing software), but I cannot seem to find adequate documentation on how to achieve this.

I am thus very interested in hearing about other options to achieve the same result. Ideas, anyone?
