Jo Shields: Sleeping with the enemy: my life with Windows Phone

In my last blog post about smartphones, I urged the universe at large to help maintain a variety of ecosystems, to help foster competition and originality amongst vendors and the same day I hit publish, WebOS was killed. Apparently the universe hates me. Since then, a few things have changed. My main phone since the day of its release was the HP Pre 3, running WebOS and whilst I still have a soft spot for the OS, the Pre 3 was simply too buggy for me to use full time. The main issue is that I use my phone as an MP3 player in the car but the Pre 3 would pause playback at the end of a track every half dozen tracks or so making it impossible to drive the 85 miles to work without needing to root around in the armrest and poke a touchscreen. Not something I really want to do whilst moving and ultimately too big a papercut to deal with. So, come the new year, I moved on to my next device, a Nokia N9 running MeeGo Harmattan. Ultimately, this was an even bigger failure for me than the Pre 3 was, and I lasted maybe two weeks with it before giving up and going back to the HP. Beyond massive usability errors in the software (especially the braindead unkillable pop-up demanding Internet access, even when none is available), the worst for me was how it handled the MP3 player task. My usual way of working is to have the phone hooked up to the stereo with a 3.5mm jack, and the car switches to headset Bluetooth profile to handle calls this is pretty common on cars too old to support A2DP profile (Stereo music-capable headphones). WebOS and Android are fine with this but not the N9. The N9, instead, will output all audio through the last connected audio device, regardless of how much that might not be helpful. Get in car, start music playing, plug in cable, start engine and it plays audio for about three seconds before the Bluetooth connects, and it switches to outputting music via the Headset bluetooth profile (not something that my car can do). Unplug and replug the cable, and music works but incoming calls are silent until I disconnect the 3.5mm jack, as it outputs the headset audio through the headphone socket. I just couldn t deal with this big a step back from WebOS as far as my workflow goes, and gave up. So, where next? Well, a funny thing happened a co-worker with generally very good instincts regarding consumer electronics usability told me that his housemate had just bought a Nokia Lumia 800 Windows phone (the WP7-based cousin to the N9) and loved it. Enough that said co-worker was considering getting one himself. This was a very strange thing to hear, especially from an iPhone owner, about a Microsoft product. I d been generally interested in WP7 on an academic level for a while, but to hear that degree of praise of the actual product was interesting. Also interesting, and roughly simultaneous, was seeing Sajid Anwar s reverse engineering of the proprietary Zune file transfer protocol go from theory into an actual set of libmtp patches. So if the capability to use Banshee to transfer music on is here or near and it can t be as braindead as Harmattan when it comes to headphone/bluetooth behaviour, then why not jump ship and squeeze a handset out of Orange? About a week after my co-worker replaced his iPhone with a Lumia 800, I bought one too. So where to begin? Well, I ll begin at the start: WP7 is a joy to use. It really just is. It s the first mobile OS to try something radically different in the UI department for years. Everyone else these days (especially Android) builds iPhone rip-offs to varying degrees, and even the iPhone interface has a lot in common with the old old OLD interfaces found on the dumb Nokia phones of the 1990s. WP7 has an interface which provides just the right level of passively visible information and interactivity, and manages to do it with an elegance that no Android home screen filled with widgets will ever manage. The uncluttered screens are easy to read, and the Metro usability paradigms are trivial to pick up and learn. Without a doubt I d recommend WP7 to friends and family from a usability perspective, and the Microsoft engineers and designers responsible for cooking up the WP7 interface are worthy of praise. And I m not the only one saying this Apple co-founder Steve Woz Wozniak recently came out with a similar line. That s the good. There s also some bad, make no mistake. I m going to cover all the reasons WP7 sucks over several paragraphs. But overall, a smartphone is a device which I expect to suck the question is how bad the suck is, and whether it gets in the way of me using the device for what I need at the time. Moreso than MeeGo, moreso than Android, and even WebOS (and I m still a big WebOS fan), WP7 has more good points than bad points. But there s still some room for improvement, and some room for caution and since I know there are a few Microsoft folks following me on Twitter, I m going to go over my prescription for continued platform success. Oh, one more thing before I start: I know WP7 isn t Free Software. As an end user, I really don t care about that. I just want something that works something I didn t get from WebOS and Harmattan, both of which are primarily Free Software stacks. I m not saying there s a causal relationship there, or that a mobile OS can t be both Free Software and good just that as an end user, my favourite platform right now is non-Free. Take from that whatever you like. It s also vitally important, as Free Software folks, never to lose sight of what the other players in the market are up to. If you can t objectively assess why people are using a proprietary option by using it & recognising its good points (i.e. what to steal & what to improve) then you can t hope to win over users. So. WP7 s downsides in detail. In-place updates. Seriously guys, even Apple can manage this now. Why can t Windows Phone? I understand that making backups is smart and all updates come with a mandatory backup but I really shouldn t be tied to a PC to update a post-PC device. Also, those backups are useless, since they cannot be restored onto replacement devices in the case of failure or theft, so fix that too. Update all the things. An iPhone sold in June 2009 still has access to the latest iOS releases. Android phones are notorious for shipping with an outdated version of the OS, then getting at most one major update over the phone s lifetime (usually the device is abandoned by its manufacturer within months of release). Which camp does Microsoft want to align with, there? Every Windows phone 7 device released should receive Windows Phone 8, even with some features disabled. Anything less is punishing every existing customer, in the hope that you ll attract new ones not a winning strategy for a fringe platform whose biggest evangelists are its users. Fix IMAP. IMAP isn t hard. Yet WP7 never seems to work properly with a subset of my mail, never showing the message body & just saying Downloading forever. Fix it. Bing sucks. Bing s search results are terrible. Either do something to make them bearable, or allow me to pick which search engine I get when I hit the search button. A Google live tile isn t the same thing. Make killing apps easier. I know you stole the WebOS card view for multitasking (hold the back button) please also steal the WebOS ability to close apps. I don t want to have to go into an app and bash back repeatedly until it quits. This is particularly annoying for Internet Explorer. Make reinstalling apps easier. If I want to install every app I previously had installed on a new device, without restoring a backup, this should be easy. There are third party apps which try to plug this gap. Find a way to support copyleft. I d like to port a few C# apps to WP7, but because they re LGPL, I can t. The code s copyright holders would have no issue with their code being on WP7, as long as end users have a mechanism to replace the libraries, so why not find a way to allow this? e.g. when compiling an app, let me mark a library as user-replaceable , then allow for some mechanism where an end user can replace those assemblies with their own version. Let me use multiple Google calendars. WP7 only lets me add/see appointments on my default Google calendar. I want to add/see things on my wife s calendar, which is shared with me. WebOS can do this. MTP-Z is the devil. I do not need or want encrypted end to end communication between my PC and my camera device, to transfer a photo off. I do not need or want encrypted end to end communication between my PC and my MP3 player to transfer a photo on. Let s be honest, the only reason for MTP-Z is to enforce DRM on Zune-rented music tracks and honestly, there s no good reason to require MTP-Z for *all* communications if all you want to do is protect one folder or file extension. Now, since MTP-Z theoretically forces me to use Zune for many tasks better handled by other apps, now I get to write multiple criticisms of Zune s desktop app and as long as MTP-Z is enforced, every Zune failing is a Windows Phone failing too. Zune: Support Windows codec infrastructure, and transcode where needed. Windows Media Player can play Ogg Vorbis files. No, not out of the box, but if one installs the required codecs. Zune should support the same files as WMP if you want to ensure people don t try to copy files to a portable device which are not supported on that device, then you should have an API in place to allow for pluggable seamless transcoding of files as required Banshee allows me to do this (e.g. to copy files I have as .flac to devices which do not support it). Zune: Search my tracks, not the web. Zune s searching is terrible it doesn t do as-you-type searches, and when I hit enter, matches from my collection are given a tiny little space compared to matches from the Zune music store. Let me easily pick the track I feel like listening to, don t make it a chore Zune: Let s solve metadata together. I absolutely love how nicely the Zune app on desktop and on phone shifts as appropriate to the currently playing artist (e.g. changing the lock screen to an image of the artist in question). However, Zune doesn t make it obvious how to set an album s metadata to support this, and it s particularly frustrating when it s a minor difference of spelling causing a track not to get the nice treatment e.g. UNKLE versus U.N.K.L.E. . Either start making heavy use of audio fingerprinting services like MusicBrainz to fill in metadata, or allow me to search for fully supported artists when filling in track metadata Zune: Random playlists are useless on devices. I like smart playlists. In Banshee, I have one to pick 12GB of random tracks, which I can sync to my phone. I can t do this with Zune. If I try to just sync all my random music to my phone, it errors out due to lack of space. If I have a random playlist, the random selection changes multiple times during a sync resetting the sync, wiping out half the tracks that were transferred on, and starting again. As a result, the sync goes on for literally hours, never ending up with more than a gig or so of tracks on the phone. Random playlists should be freezable, so I can transfer them to my device in peace, then get a new random selection when I want. So, that s my list of miserable failure and it s still a less painful list than any other mobile OS I ve used. Perhaps one day Android will approach being usable, perhaps Blackberry s BBX will actually appeal to human beings rather than corporate IT managers, and perhaps Mozilla s delightfully named Boot to Gecko will get some traction. Who knows. All I know is, My Lumia 800 is the best phone I think I ve ever owned, and it s important for anyone working in the mobile space to understand why.

Michal Čihař: Weblate 1.0

After few weeks of heavy testing, Weblate 1.0 has been released today. Compared to 0.9 there are just minor changes and bug fixes. The most important thing is that Weblate should be now really ready to use :-). Full list of changes for 1.0: You can find more information about Weblate on it's website, the code is hosted on Github. If you are curious how it looks, you can try it out on demo server. You can login there with demo account using demo password or register your own user. Ready to run appliances can be found in SUSE Studio Gallery. Weblate is also being used https://l10n.cihar.com/ as official translating service for phpMyAdmin, Gammu, Weblate itself and others. If you are free software project which would like to use Weblate, I'm happy to help you with set up or even host Weblate for you (this will be decided case by case as my hosting space is limited).

Raphaël Hertzog: The Debian Administrator s Handbook is available

The Debian Administrator's Handbook CoverI am so glad that we managed to complete this project. Roland and I have spent countless hours on this book since December, both for the translation itself and also for all the things that we tend to forget: a nice book cover, a great book layout for the print version, coordinating the work of reviewers, registering as an editor to get an ISBN, etc. I think I will come back to this in a future article because some parts of the story are interesting. In the mean time, enjoy the DFSG-free Debian Administrator s Handbook: Check out the official announce (there s a discount for early buyers of the paperback).

DebConf team: Submit your greatest ideas as a DebConf12 talk (read: Call for Papers reminder) (Posted by Gunnar Wolf)

DebConf12 is drawing closer and closer! Have you ever been to a DebConf? You will surely agree with us: It s a life-changing event! It s one of the greatest geek gatherings in the world! It s something you can t afford on missing out! It s wait.. Oh, sorry, I had my spam mode set to highest. But still, that does not make it any less true. And one third of May has already passed. This means that the first deadlines are just around the corner: next Tuesday (15-may), sponsored registration will close, so make sure to register before it s too late. But wait wasn t this about the call for papers? Right, that s not the point of my post, I wandered off again. I m sorry, I just visited Managua last weekend (Holger will soon tell you about our visit), and it s impossible to keep the mind off the excitement. I wanted to ask you to share your greatest, latest ideas or projects. DebConf is about many things But one of its most important features is its rich set of talks, usually with very high and interesting contents in the technical, social, organizational levels Or several of them at once. As always, you will be able to submit talks until a day before you present it. However, it s best for your intended audience to know bits about your proposed topic, possibly even to share some information beforehand, so that the exposition can be as smooth as possible and the interaction during the talk even more And this is specially true for BoF sessions. However, we do have one advertised deadline: Talks submitted up to June 1st will be considered to be pre-scheduled. This means, to be part of the officially announced program, and have guaranteed coverage of our (always great) video team. DebConf Tracks But maybe you don t feel comfortable presenting a topic. Or you are, but you think it would be important to have several thematically related talks be grouped together. And if you are interested in this group of talks, you will probably know who would be more interesting to invite to present the topics - And will be able to prod them to do so. You can request to coordinate a track. That will ensure you get a contiguous block of timeslots for the talks you schedule, and do a great contribution to DebConf. To add your track, please mail talks@debconf.org. Please, specially if you do so in the few days following May 9, send me a copy to gwolf@gwolf.org, as it seems the alias is not yet set up. Tutorials and mentoring This year, we will have a high number of very motivated attendees from the many countries in the Central American region who want to get started in helping Debian, but have not yet found how to do it. Usually we would see local communities as prime material for DebianDay However, many of them are more interested in getting hands-on tutorials and be mentored into contributing to Debian. So, if you are part of a team working on a given aspect of Debian, or want to get people involved into your project, register it in the Tutorials and mentoring track. See you all soon, very soon, in tropical Managua for the hottest DebConf ever! (oh For those who remember days long past in Helsinki: There is even a sauna! ;-) And it s GREAT)

Leandro Gómez: Are you going to DebConf12?

There s only a few days left before the sponsored registration for DebConf12 closes. If you haven t registered yet, please do it before May 15th and consider submitting a talk. We re looking forward to see you in Managua in July!

Norman García: Debian tour in Nicaragua

In April, the Nicaraguan Debian community started the Debian Tour, a series of talks in different universities around Nicaragua in order to promote Debian GNU/Linux and invite people to join our community.

The Debian Tour kicked off in the city of Masaya and we plan to visit other cities, like Le n and Chontales. In April we had two events, and we re planning four more events in May and an additional four in June for a total of 10 events, but hopefully we can do more :) At this time we have scheduled two visits to UNAN (Universidad Nacional Aut noma de Nicaragua), one in May and one in June, and one visit to UNI (Universidad Nacional de Ingenier a) and one more to UENIC (Universidad Evangelica de Nicaragua) in Masaya. Besides talks, we had one workshop with the help of the guys from UNI about Debian packaging by gwolf who was visiting Nicaragua last weekend. There are a few other workshops planned about sysadmin and security in Debian. I want to participate in Debian Tour but I still don t know how, maybe give a talk about LXDE or collaborating with Debian.

Iustin Pop: pbuilder and binary-arch packages

Just got bitten by this, so note to self: Yes, I'm talking about Debian bug #671981. Fun!

Tim Retout: Engaged!

Following on from the weekend of change, I've got engaged to Kate. :) We now need to organise a combined housewarming/engagement party...

Vincent Sanders: NetSurf at a show

The wakefield RISC OS show is an event the NetSurf project has attended for a long time. in fact since 2005 when the "stand" was a name on an A4 sheet through 2006, 2007, 2008, 2009, 2010 to 2011 we have always been present.

The event has changed in that time from a large affair with many exhibitors to a small specialist interest event with a handful of stands. I took some pictures this year which give a fair impression of the event.

We were seriously considering not attending this year as 2011 had seen us barely break even on donations versus expenses to attend. However we decided that the projects annual Grey Ox Inn post event dinner was probably worth making the effort.

So we all met up in a hotel just off the M1 near Wakefield and set up our table. And although NetSurf as a project now has much more usage on other platforms we still represent the principle browser for the RISC OS platform!

We had a pleasant time, talked to a lot of users and made our expenses back in donations. Overall an amusing Saturday. Based on the size of the event and number and age of the attendees, I fear the RISC OS may be destined for the history books.

Vincent Sanders: Repaying a debt

Some debts are merely financial and some easily repaid but some require repayment in kind . Few debts are more important to me personally than a favour earned by a good friend.

Several years ago, before I started this blog, I replaced the kitchen in my house. Finances were tight at the time and I had to do the entire refit with only limited professional help. Because of this I imposed upon Mark Hymers and Steve Gran to come and assist me. They worked tirelessly for three days over a bank holiday for no immediate reward.

Mark and Steve with a drill
This weekend I had the opportunity to assist Mark with his own kitchen refit and reply my debt.

Although the challenges have been different on this build they were, nonetheless present, including walls which were most definitely not square and affixing cabinets 10mm too high so the doors could not close.

We also got to make a hole for a 125mm extractor which was physically demanding and not a little tiring (Steve actually wielding the drill had a fabulous aim)

I took some photos to document the process which has resulted in an image which is positively threatening, though the two of them are nice people really!

All in all a pleasant weekend with friends, the whole favour thing was really moot, I would have done it for a friend anyway.

James Bromberger: Courier IMAP and FAM

Last Friday, while tracking Debian Testing, the courier package was updated, and while authentication could be seen to be successful, actually using IMAP seemed to fail. Turns out the FAM package was somehow to blame; installing fam and libfam0 was the solution. This uninstalled gamin for me. So if you re pulling your hair out with a similar courier/imap issue, then perhaps have a look at the courier-imap mailing list.

Joachim Breitner: Free Groups in Agda

I must say that I do like free groups. At least whenever I play around with some theorem provers, I find myself formalizing free groups in them. For Isabelle, my development of free groups is already part of the Archive of Formal Proofs. Now I became interested in the theorem prover/programming language Agda,so I did it there as well. I was curious how well Agda is suited for doing math, and how comfortable with intuitionalistic logic I d be.
At first I wanted to follow the same path again and tried to define the free group on the set of fully reduced words. This is the natural way in Isabelle, where the existing setup for groups expects you to define the carrier as a subset of an existing type (the type here being lists of generators and their inverses). But I did not get far, and also I had to start using stuff like DecidableEquivalence, an indication that this might not go well with the intuitionalistic logic. So I changed my approach and defined the free group on all words as elements of the group, with a suitable equivalence relation. This allowed me define the free group construction and show its group properties without any smell of classical logic. The agda files can be found in my darcs repository, and the HTML export can be browsed: Generators.agda defines the sets-of-generators-and-inverses and FreeGroups.agda (parametrized by the Setoid it is defined over) the reduction relation and the group axioms. Here are some observations I (disclaimer: Agda-beginer) made: If I were to extend this theory, there are two important facts to be shown: That there is a unique reduced word in every equivalence class (norm_form_uniq), and the universal property of the free group. For the former (started in NormalForm.agda) I m missing some general lemmas about relations (e.g. that local confluence implies global confluence, and even the reflexive, symmetric, transitive hull is missing in the standard library). For the latter, some general notions such as a group homomorphism need to be developed first. I planned to compare the two developments, Isabelle and Agda. But as they turned out to show quite things in different orders, this is not really possible any more. One motivation to look at Agda was to see if a dependently typed language frees me from doing lots of set-element-checking (see the mems lemma in the Isabelle proof of the Ping-Pong-Lemma). So far I had no such problems, but I did not get far enough yet to actually tell. Thanks to Helmut Grohne for an educating evening of Agda hacking!

Lars Wirzenius: Quality of discussion in free software development

The Online Photographer has a meta-article on some discussion in the photography world. Summary: someone wrote an opinion piece on one site, and people on the discussion forum of another site got his name wrong, possibly repeatedly. And the quality of the discussion went down from there. The quality of the discourse of free software development is frequently of some concern. Debian has a reputation as being a host to, er, particularly vigorous discussions. That reputation is not unwarranted, but, I think, we've improved a lot since 2005. The problem is hardly restricted to Debian, however. How can we improve this? I don't know. As a community, I'm not even sure we agree what the problems are. Here's my list. Insults, personal attacks, and other such outrageously bad behavior is uncommon. It crosses the line so clearly it becomes easy to deal with; I don't think handling this needs much attention. What can we do about this? I'm not sure. I have, for the time being, abandonded Debian mailing lists as a way to influence what goes on in the project, but that's just a way for me to clear some space in my head and time in my day to actually do things. My pet hypothetical solution of the day is that mailing lists might raise the quality of the debates by limiting the number of messages written by each person per day in each thread. This might, I think, induce people to write with more thought and put more effort into making each message count.

Cyril Brulebois: Debian XSF News #12

Time for a DXN#11 follow-up.
  1. The recent xserver-xorg-input-synaptics rc4 upload solved a lot of issues, but the 1.6.0 release (just uploaded) should fix some more. Enjoy!
  2. I ve also uploaded a new xorg-server, merging from upstream server-1.12-branch to get many XI2.2 bug fixes, along with an infinite loop bug fix (also seen with synaptics).
  3. Many drivers can no longer work on ia64 due to the recent changes, so we requested they be removed, which happened promptly!
  4. All XSF-maintained packages build happily against X server 1.12, meaning users can get back to running apt-get dist-upgrade blindly without having to fear the consequences. Pro tip: when you see something like xserver-xorg go away during a dist-upgrade, think twice before confirming!
  5. xf86-input-mtrack was recently fixed; xf86-video-glamo and xf86-video-msm fail to build (#671028, #671806), so they stay uninstallable for now. Thankfully nothing appears to depend on them, so they can be temporarily removed from testing if needs be.
  6. In the meanwhile, xserver-xorg-video-intel 2.19 was released. It will probably land into experimental first, until the new server and its drivers make it into testing.
  7. Andreas Beckmann asked me to mention the status of the binary drivers, so here is my take about them: fglrx still doesn t support X server 1.12 (LOL!). The other, big fat blobby driver is installable, and supposed to work.

Stefano Zacchiroli: overlapping bits from the DPL for April 2012

Just posted to d-d-a, here is the monthly report about my DPL activities.
Dear project members,
last bits of the past DPL term and first bits of the current term, all in one. Here is a report of what has happened in DPL land last April. Highlight: call for DPL helpers Before the report, though, let me point out that your friendly neighborhood DPL could use some help. As discussed during campaign, there are some intrinsic transparency and scalability limits in the DPL institution, when run by a single person. Before trying something new to fix that, I'd like to give a last try to an old "tactic": calling for help. If you're considering running for DPL or if you're simply interested in the job the DPL does and willing to help with that, please let me know. Ideally, if I find a group of people I'm happy to work with, I'd like to set up periodic IRC meetings with all "DPL helpers" to publicly discuss items in the DPL agenda and share the work-load. Ongoing discussions A big topic of last month has been the proposal by Francesca Ciceri to publish a diversity statement for the Debian Project. After a lively discussion on -project, we reached consensus on a text, and I've been happy to help with that. To finalize statement publication we now need to vote on it with a GR. I've helped drafting a corresponding GR proposal that has already been posted to -vote by Francesca. A final one, looking for seconds, will be posted there soon. Wrapping up March discussions on a revenue sharing agreement with DuckDuckGo, I've announced my intention to finalize the agreement and have done so shortly thereafter. The Iceweasel maintainer has deployed the corresponding search engine query string and other web browser maintainers could do the same, if they want to. In April I've also spent some time to move forward the long running conflict on Python maintenance, reported to the tech-ctte more than 2 years ago. With the help of people on the -python mailing list, I've now submitted to the tech-ctte an up to date list of potential maintenance teams. I hope the tech-ctte now have all the information needed to come to a decision. Speaking of which, I'm also discussing with tech-ctte members the possibility of having periodic ctte meetings; the idea is to ensure that outstanding issues are periodically reassessed, improving the reliability of tech-ctte decision times. I've also discussed at length with members of the pkg-multimedia-maintainers team the relationships with the unofficial debian-multimedia.org (d-m.o) repository, that have been a cause of tension for Debian multimedia users and maintainers for quite some time. On behalf of the team and of the Project I've now reached out to the d-m.o maintainer, hoping to come to some sort of amicable agreement on which packages belong where. Hardware replacement As anticipated in last report, I've started approving hardware purchases to implement the yearly hardware replacement plan prepared by DSA. During April I've approved requests to buy servers to replace the machines running the bugs-master, bugs-mirror, and UDD services. The total expected expenditure is about 15'000 USD. Communication I've delivered my classic Debian "18^W 19 years" talk at UNIVPM, a polytechnic university in center Italy; slides are available. I've then been contacted by people from the European Synchrotoron in Grenoble who, beside having recently migrated their infrastructure to Debian, are looking into organizing a workshop on Debian usage for large science facilities. I've been happy to help out providing a list of potential topics and speakers for the event. Also as anticipated last month, the Debian Project has been present at the OpenStack summit. Loic Dachary has represented Debian at the event and provided a nice report about his experience there. Speaking of which, I've also coordinated a news release about the availability of cloud technologies in Wheezy, taking the chance to point out the relationships between what Debian stands for and the ability to deploy your own private cloud. Sprints April has been a rather calm month on the sprint front, with the notable exception of the I18n team who is organizing a sprint for June in Paris. Miscellanea Thanks for reading thus far,
HDH! (Happy Debian Hacking)
PS the boring day-to-day activity log for April is available at master:/srv/leader/news/bits-from-the-DPL.txt.201204

Russell Coker: A Quick Review of the Mac Mini with OS/X Lion compared to Linux

A client just lent me a new Mac Mini with OS/X Lion to play with. I think it s interesting to compare it with regular PCs running Linux. Hardware The Mac Mini is tiny. It s volume can be compared to that of a laptop. The entire outside apart from the base is made from aluminium which helps dissipate heat, it s not as effective as copper but a lot better than plastic. The ports on the system are sound input/output, 4*USB, Ethernet, Firewire, Thunderbolt (replacement for Firewire), SDXC, and HDMI. It ships with a HDMI to DVI-D adapter which is convenient if you have an older monitor (or if you have a recent monitor but no HDMI cable as I do). To open the case you unscrew the bottom, this is much like opening a watch. Also like opening a watch it s not particularly easy to screw it back on tightly, I will probably return the Mac Mini without managing to completely screw the base in. The hardware is very stylish and intricately designed, what we expect from Apple. It s also quiet. In every way it s a much better system than the workstation I m using to write this blog post. The difference of course is that this workstation was free and the Mac Mini cost just over $1000 including the RAM upgrade. A Mac Mini could be a decent Linux workstation and if I see one about to be recycled I ll be sure to grab it! Installation The Mac OS comes pre-installed so I didn t get to do a full installation. When I first booted it up it asked me if I wanted to migrate the configuration from an existing server, I don t know how well this works as I don t have a second Mac system but the concept is a good one. Maybe having full support for such a migration process would be a good release goal for a Linux distribution. After determining that the installation is a fresh one I was asked for a mac.com email address or other form of registration. I skipped this step as I don t have such an email address, but it could be useful. Red Hat has Kickstart to allow configuration of an OS install based on a file from a server (via NFS or HTTP). Debian supports preseeding to take OS configuration options from a file at install time [1] and the same option can be used for later stages of OS autoconfiguration. One thing that would be really useful is to allow the user to enter a URL for configuration data for an individual account or for all accounts, so someone with an account on one workstation could upload the configuration (which would be either encrypted or sanitised to not have secret data) and then download it when first logging in to a new system. I can easily take a tar archive of my home directory to a new system, but people like my parents don t have the skill to do that. One of the final stages of system configuration was to identify the keyboard. The system asked me to press the key to the right of the left shift key and then the key to the left of the right shift key and then offered me three choices of keyboard. That was an interesting way of reducing the list of possible keyboards offered to the user and thus preventing the user from selecting one that is grossly incorrect. Cloud Storage When first logging in I was asked for an iCloud [2] login. iCloud doesn t seem like a service that should be trusted, it s based in the US and has been designed to facilitate access by government agencies. Ubuntu One [3] is a similar service that is run by a more reputable organisation, but the data is still stored by Amazon (a US corporation) which seems like a security risk. Ubuntu One isn t in Debian (which is strange as Ubuntu is based on Debian) so it was too much effort for me to determine whether it encrypts data in a way that protects the users against US surveillance. The cost of Ubuntu One storage is $4 per month with music streaming. A better option is to use a self-hosted OwnCloud installation for a private or semi-private cloud [4]. A cheap server from someone like Hetzner (E49 per month for 3TB of RAID-1 storage) [5] is a good option for OwnCloud hosting. A cheap Hetzner server is about $US64 per month (at current conversion rates) which is equivalent to about 16 users of Ubuntu One for music streaming. So if 20 people shared a Hetzner server they could save money when compared to Ubuntu One while also getting a lot more storage. I ve got about 300G of unused disk space on the Hetzner server that hosts my blog and when the system is migrated to a newer Hetzner server with 3TB disks it will have 2.5TB of unused space, I could store a lot of cloud data in that! The main features of iCloud and Ubuntu One seem to be distribution of random data files (anything you wish), streaming music to various playing systems, and copying pictures from phones as soon as they are taken. These are all great features but it s a pity that they don t appear to support distributed document storage. Apple Pages apparently allows documents to be immediately saved to the cloud. I d like to be able to save a file with Libre Office at home and then access it from my netbook using the cloud, of course that would require encryption for secret files but that s not so hard to do. One advantage with such distributed storage is that when combined with offline-IMAP for email it would almost entirely remove the need for backups of the desktop systems I maintain for my relatives. I could have all their pictures and documents go to the cloud and all their email stay on the server so if their desktop PC dies I could just give them a new PC and get it all back from the cloud! OwnCloud supports replication, so if I got two servers I would be covered against a server failure. But I think that for a small server with less than a dozen users it s probably better to just take some down-time when things go wrong and do regular backups to an array of cheap SATA disks. App Store Apple has an App Store in the OS. The use of such a store on a desktop OS is a new thing for me. It s basically the same as the Android Market (Google Play) but on the desktop. I think that there is a real scope for an organisation such as Canonical to provide such a market service for Linux. I think that there is a lot of potential for apps to be sold for less than $10 to a reasonable number of Linux users. A small payment would be inconvenient for the seller if they have to interact with the customer in any way and also inconvenient for the buyer if they are entering all their credit card details into a web site for the sale. But for repeat sales with one company being an intermediary it would be convenient for everyone. A market program for a desktop Linux system could provide a friendly interface to selecting free apps from repositories (for Debian, Ubuntu, Fedora, or other distributions) and also have the same interface used for selecting paid applications. Conclusion This isn t much of a review of Apple OS/X or the Mac Mini. Thinking about ways of implementing the best features of Lion on Linux is a lot more interesting. I admire Apple in the same way that I admire sharks, they are really good at what they do but they don t care about my best interests any more than a hungry shark cares about me. Update I got the currency conversion wrong in the first version of this article. It seems that to save money via a shared Hetzner server instead of Ubuntu One about 20 users would be needed instead of 10. But that s still not too many and would still give a lot more storage. It would be a little more difficult to arrange though, probably anyone who is seriously into computers knows 10 people who would want to share such a service (including people like their parents who want things to just work and don t understand what s happening). But getting 20 people would be more difficult. Related posts:

Gregor Herrmann: RC bugs 2012/17-18

as I was mostly offline last week, this is a report covering two weeks. as in the week before, it's mainly a mix of build-arch & gcc 4.7 bugs.

Maximilian Attems: Gnome shell rocks

The Gnome shell is a great step. Finally the Linux default Desktop is not only useful (as Gnome 2.X used to be), but also stylish and modern. It's a different kind of desktop, which seems to irk desktop habits of some peoples. I'm proud to show it off. This happened for the last time years ago while doing some funny config quirks of fvwm. Gnome 3.x is cool. (: Also the customisability via all the extensions is fun. What I do miss is the gnome weather (There used to be an incarnation with plenty of geographical sites, which got somehow got axed later.) and more packaged extensions for out of the box deployments (wish #661782). I seem to be too lunatic to find session settings in "System Settings" for having startup applications run or the used applications reopened (please yes evince show the same pdfs). The other minor critic is that "System Settings" is quite empty, but has on each system a funny advertisement for "Wacom Tablets". Ah and after a myriad of suspends and network-manager stops/restarts gnome-shell likes to segfault, which is no nuisance as it restarts.

Eddy Petrișor: Homeopathy, there's nothing in it, but is expensive

To add insult to injury, homeopathy is not only inefficacious, it's expensive, too.
A whole pack of an absurd dilution of a non-existent thing is the most expensive product on that advertising. Are we living an an age of insanity or what? If you want to know what really is homeopathy and why is dangerous, you can read here.

Clint Adams: IronyFest 2012

I attended a hackfest for the alleged purpose of furthering data transparency and other such entertainment. I expected a full-blown circus of idiocy based on the lead-up: instructions to sign up to websites for the purpose of Centralizing things, downloading iPhone SDKs, and other blatant evidence of Not Actually Getting It At All. Imagine my surprise when I get to the registration desk and they offer me a photography opt-out. Now everyone knows that privacy opt-outs don't work; either they're ineffective or they are effective at a cost far greater than anyone should pay, but I appreciated the gesture anyway. So I received a badge advertising my first name and the fact that I was unwilling to be photographed. Spoiler alert: I was photographed at least six times. I have now cleverly changed my hairstyle so that no one can recognize me. After people had arrived and rubbed elbows and consumed things, the grand dignitaries took the stage for spectacles of egoism so great that relativity made Dan Kaminsky look almost like a humble and reasonable human being. This was succeeded by some organizing, coding, and ridiculousness. The group I landed in contained two employees of the advertising industry and one of the U.S. government. There was also someone I refer to as "ultracompetent astronut". Some things that were apparent: people
