LinuxCon 2013 Europe was this week... and videos from it have started being published. Here's a video with our favorite Linux leader about the future of the Linux kernel. Enjoy!
Oh, and here is the Kernel Developer Panel
MontanaLinux: Please tell me about yourself... as much as you feel comfortable with... as open or as closed as you want to be... family, education, work, hobbies, religion, volunteering, diet, music tv / movies, etc.
Máirín Duffy: Let's see if I can cover all of those in one sentence. I'm a married vegetarian Roman Catholic mom and RPI alumna living in Boston who is happily employed at Red Hat as an interaction designer and occasionally teaches kids how to use FLOSS creative software, and additionally am a big fan of Zooey Deschanel (so I like New Girl and She & Him.)
ML: What software-based graphics tools have you worked with in the past and what currently are your favorite applications?
MD: My first digital painting program was the Smurfs Paint 'n Play for the Coleco ADAM. When we finally got a PC with a VGA card, I used Deluxe Paint II and the Disney Animation Studio painting programs. I used Photoshop and Gimp when I was in high school and was introduced to the Macromedia tools in college. My tools of choice in college were Macromedia Fireworks for almost everything, and Adobe Illustrator, Macromedia Director, and Macromedia Flash for everything else. I followed sodipodi and I switched over 100% to FLOSS tools around Inkscape 0.39.
At this point I've been using a fully FLOSS creative work flow for around 7 years — starting with Inkscape and Gimp on Fedora and branching out to Scribus, MyPaint, Krita, Blender, Darktable, etc. as new applications became available. Inkscape is by far my favorite graphics tool and I use it for almost everything.
ML: Are there any hardware accessories that you like to use in your daily creative work? ...and if so, please tell me about them.
MD: I have a Lenovo x220T which is a laptop with a swivel-screen that has a built-in Wacom tablet and stylus. I use it often when I need to do illustration work; it's good for sketching, too.
ML: I believe you have done some FOSS training sessions at a few educational institutions. Please tell me about those experiences and do you hope to do more of those in the future?
MD: I've done a lot of sessions, but the two longest ones were probably the Inkscape class I did at a middle school near Red Hat's Boston-area office (10 weeks) and a Gimp and Inkscape class I did with the Girl Scouts in Boston (8 weeks.) (You can read more about each respectively at http://opensource.com/education/10/4/introducing-open-source-middle-school and http://blog.linuxgrrl.com/category/girl-scouts-class/)
It is a lot of work to put together classes like that, but working with kids is really fun. The thing about these classes is that the kids get to keep the software. For example, I found out that a student I taught in one of the classes still uses Inkscape at home and entered an art contest with a design she made in it well after the class was over. You know, when I was a similar age to those kids, I was a student in an outreach program at the school that later became my alma mater (RPI.) We were taught character animation in Macromedia Director. Not only could I not go home after the class was over to practice and build on my skills because I didn't have the software — it was quite expensive back then — but by the time I entered college Macromedia Director was basically sunset as a product in favor of Flash. Is there anything today that can even open up *.dcr files from Director? My Director projects are probably bitrotted forever, and I'm not that old.
I think us folks in the FLOSS world take it for granted that there are these amazing and free tools using open standards right at our fingertips and the more we can share and teach them to others, I truly believe the world will be a better place.
ML: What FOSS / Linux conferences have you participated in? Have you given any presentations and if so, on what topics?
MD: I have; probably too many to list them all at this point. I was just at Grace Hopper a couple of weeks ago and participated in the Open Source Day Systers Mailman 3 Hackfest (got a few commits in to Mailman 3 too!) Last year, I gave a talk at the Red Hat Summit OpenSource.com panel about FLOSS creative software. I keynoted at Software Freedom Day Boston a couple years ago or so about attracting more designers to FLOSS. I gave a talk at the Linux Plumbers' Conference a couple years ago about storage technologies and UX (related to some of the Anaconda design work I did.) I wrote a paper about designing for free software as part of an open source workspace at the ACM CHI conference in 2010 (http://blog.linuxgrrl.com/2010/04/06/contributing-to-free-open-source-software-as-a-designer/.) I've also given talks at the Libre Graphics Meeting, SXSW, GUADEC, FUDCon, LibrePlanet, FOSS.in, LinuxCon, and probably others I'm not recalling at the moment.
ML: Do you consider yourself a technology lover? If so, do you have any visions of the future you'd like to share?
MD: I learned how to read by playing text-parser adventure games on an old 8088 machine; I grew up with a love of technology and auspicious thoughts for a future with even better technology. Unfortunately, I'm a bit more cautious about technology now - particularly tablets and phones. I'm a new parent, and I worry about the ubiquity of these devices and how they may affect childrens' development. It's also sad to go to pretty much every public place and see heads bent down staring at screens rather than healthy social interaction (I'm as guilty as anybody.) What about the divide between people who can afford these devices and a ubiquitous internet connection and those who can't? There's bad that comes with the good that technology brings, and I think a lot more careful thought and action needs to be put into mitigating that bad.
ML: What hardware have you purchased for yourself? Do you have a laptop, smartphone and/or a tablet? If so, what?
MD: I have an x220T tablet, a Samsung Galaxy S4, and a Nook HD. I've never purchased a piece of Apple hardware in my life, although I was - oddly enough - given a gumstick iPod Shuffle once when I signed a lease on an apartment. It bricked after a few months.
ML: Do you use any non-FOSS software? If so, what and why?
MD: The only non-FLOSS desktop software I use is my income tax software. I have it installed on a hard drive with a Windows install on it that came with my husband's personal laptop before we swapped an SSD into it. I use that once a year, because I'd rather do my own taxes and the laws change too frequently for any potential FLOSS solution to be workable.
I do have more non-FLOSS apps on my phone than I'd like to admit, and I use more non-FLOSS web apps than I'd prefer (although many are FLOSS.) I used to not even use Flickr or Twitter because they aren't open source - as I get older, I think I'm getting more soft in tolerating that. One piece of proprietary software I'm particularly proud of avoiding, though, is Gmail.
About your work with Red Hat
ML: How long have you worked for Red Hat and what positions have you held there?
MD: I've worked for Red Hat close to 9 years, if you don't count my summer internship before I started full-time. I've been an interaction designer the entire time, but I have worked on different teams over the years.
ML: What projects have you worked on within Red Hat?
MD: I've worked on a lot of projects over the 9 year period so it would be boring to list them all out. The two main products/projects I've worked on are Red Hat Network / Red Hat Network Satellite and Fedora. As of late I've been spending a lot of time on Hyperkitty, the mail archiver web UI for Mailman 3.
About your work with the Fedora Project
ML: How did you first get involved with the Fedora Project?
MD: I used Red Hat Linux when I was a high school student but was converted to Debian in college. I migrated to Fedora and got involved with the Fedora Project when I did a summer internship with Red Hat's desktop team in the summer of 2004.
ML: What things have you worked on in Fedora?
MD: A lot of things! I've been the community design team lead for several years at this point, which has involved a lot of wrangling to get the artwork ready for each release on time, although honestly gnokii (Sirko Kemter) does a lot of this work now - he makes sure things are ready and prepares a lot of the release artwork. Most recently on the Fedora design team I've done a lot of artwork for the Fedora Badges system (badges.fedoraproject.org) I redesigned the fedoraproject.org website with a team of Fedora design team members in 2009-2010 although it is due for some updates these days, I think. I've done a lot of UX work for a lot of different components that are in Fedora, including virt-manager and anaconda, the installer. I've also done UX work for some of the infrastructure applications that help run Fedora, including the Fedora Packages app (http://apps.fedoraproject.org/packages). I've served on the Fedora board too, but not a full term.
ML: What do you think Fedora's strengths and weaknesses are both as a FOSS development project and as a general purpose Linux distribution?
MD: By development project, I'm assuming you mean a FLOSS project community and not necessarily a development platform (but please correct me if I'm wrong.) As a community I think Fedora has a major strength in that it attracts many smart and passionate folks. The corresponding weakness (which is shared by other FLOSS projects) is that demographically it's not a particularly diverse set of folks. We are actively working on that though; for example, Fedora has participated in the FLOSS Outreach Program for Women in the past couple of rounds or so.
Another strength of Fedora is that as a community, Fedora is particularly concerned about openness and transparency with respect to project discussion but also privacy when it comes to personal information — so much so that, for example, when we proposed a Fedora badge for folks voting in a vote to choose wallpapers, we had to make the badge an opt-in badge rather than automatic because concern was voiced about individuals' privacy with respect to whether or not they voted. Folks aren't just interested in software freedom; they are interested in other social justice issues (like privacy) as well. A weakness to counter that is that in a community of passionate people, the discussions can get pretty heated — particularly on the mailing lists. This is also not unique to the Fedora Project. We are hoping to help tame the flames with affordances provided by Hyperkitty, when it's ready.
As a general-purpose Linux distribution, I think Fedora's strengths are that you have highly-skilled, full-time software developers alongside community developers putting out software in Fedora first. The corresponding weakness is that because there's new technology in Fedora first — for example, systemd or GNOME 3 — when you use Fedora you have to learn the new things sooner than other distros' users since you're getting it first. That can take time; there might not be as much documentation and as many how-to blogs available yet to learn because the tech is so new.
ML: What things would you change about Fedora if you had a magic wand?
MD: If I had a magic wand, Hyperkitty would be ready and deployed across all of the Fedora mailing lists and we'd be having much more productive and efficient conversations!
About your Anaconda design work
ML: Anaconda is the installer that Fedora uses on the install and live media. Why did Fedora need to redesign Anaconda?
MD: Will Woods covered this much better than I could in a two-part blog series that starts here:
Adam Williamson and I wrote this too to go along with the initial release of the new UI:
The redesign was initiated by the development team. The design wasn't conjured up first and then pushed on to them. They made a decision that a redesign had to be done, and they sought out UX help for the UI part of it. That is how I became involved in the project. A lot of underlying problems with Anaconda were addressed - quite well - by the development team but haven't gotten as much attention as the UI because the UI is simply more visible. (The two links above give specific examples.)
ML: Is the Anaconda redesign completed or is it an ongoing process?
MD: The major chunks of it are completed, but improvements are an ongoing process. We've done several usability test rounds (with the help of two interns, Stephanie Manuel and Filip Kosik), including a couple where we performed tests at DevConf.cz in Brno, Czech Republic and in Red Hat's Boston-area office. You can see the test documents from those tests here: https://fedoraproject.org/wiki/Anaconda/UX_Redesign#Usability and a summary of the analysis from the test results from Brno https://www.redhat.com/archives/anaconda-devel-list/2013-April/msg00018.html and Boston https://www.redhat.com/archives/anaconda-devel-list/2013-April/msg00011.html. We combed through all of the test videos and reports and incorporated some user feedback we'd gotten on the redesign as well and came up with an exhaustive list of issues to address, many of which have already been addressed: http://fedoraproject.org/wiki/Anaconda/UX_Redesign/Usability_Test_Suggestions
The Anaconda developers, as they encounter usability-related UI bugs, will often consult with me or other UX folks to hash out a solution and then fix the bugs.
So the redesign isn't stagnant; as bugs filter in they are addressed on top of our active work to identify issues and address them through QA and usability testing.
ML: What has been the most challenging part of the redesign?
MD: The most challenging part of the redesign (which my vent^W talk at the Linux Plumbers' Conference a couple of years ago actually focused on) was any interaction involving storage technologies. I actually converted that talk into a blog, so if you want to go more in depth on this you can take a look at that: http://blog.linuxgrrl.com/2013/01/04/storage-from-a-ux-designers-perspective/ Storage technology is all over the place and I think it's a bit of a miracle it is as standardized as it is. There are so many tough situations you can get into when you get storage wrong. (An example from Anaconda: http://blog.linuxgrrl.com/2013/03/04/refreshing-storage/)
ML: I must admit that when I first encountered the partitioning screens starting with Fedora 18, I was not fond of them. For various reasons, I do a lot of Fedora installs and eventually it grew on me... but I still hear quite a bit of complaining. How much and what feedback have you gotten from the community?
MD: The main feedback we get about most of the new Anaconda screens is either complaining about the position of the 'done' buttons in the upper left (folks want it in the lower right) and the text of the 'done' button (it's previously been 'back,' and we got complaints then because it doesn't always mean back, so we changed it to 'done.')
I think these complaints are symptoms of the hub and spoke model we've chosen to go with. For most of the screens, hub and spoke works great. Where it falls apart is the storage-related screens, because the storage 'spoke' is actually a little mini linear wizard in itself. I'm not convinced that hub and spoke generally was the wrong model to go with, but we've been making small tweaks here and there to the storage area so that it'll make more sense based on the usability test results and feedback we've gotten.
I also think some of these issues are symptoms of a design goal we had — make it possible for less-experienced users who just want a working system without much fuss to get one. In the design, I think I tried a bit too hard to prevent those users from being exposed to more complicated bits like custom partitioning. I mean, where I was coming from was reasonable: if you know how to create a RAID 4 array and you can actually recite the difference between all of the RAID levels, you're probably smart enough to poke around and find what you want. If 'RAID' makes you think of bug spray in all-caps, you back away slowly from the computer if you encounter any form of custom partitioning. Again, though, I think I made some bad calls there and those are shaking out in the usability test results and user feedback.
Actually last week I talked to Chris about instead of only having custom partitioning accessible from the 'Done' button on the first storage screen, to also have a button to just go to it since many people want to go there and aren't sure how when they get to the first storage screen. (It really is not intuitive to hit 'Done' to get to custom partitioning.) I'm hoping to mock up the fix this week. (I know this does seem a bit late to get to it, but to be fair I was on maternity leave for much of the Fedora 19 development cycle.)
ML: What complaints have you encountered and how valid do you think they are?
MD: That's a particularly broad question so I'll answer it broadly with respect to the user feedback we've gotten. Generally, I was pleasantly surprised by the feedback we got on the UI part of the redesign. Any time you embark on a major redesign — especially if the thing you're redesigning has been pretty much the same for a 10-year long period — you're going to get backlash. The things folks had the most trouble with were the parts of the redesign I knew were weak (particularly storage.) The parts of the design I thought worked well, for the most part, didn't receive a lot of complaints. I was seriously expecting hate mail, but I didn't receive any. I actually received a few well-reasoned and productive critiques that then went straight into the 'Usability Test Suggestions' wiki bucket list of items to address. The most common off-the-cuff feedback I hear is along the lines of, "I didn't like it at first, but now that I've had time to get used to it, it works fine for me."
I think a big reason for the less-severe-than-expected and surprisingly-helpful-feedback was how open we were with the redesign and rewrite process — I worked pretty hard to blog our major design decisions and process and the Anaconda team are very open in IRC and on the anaconda mailing lists. If someone was really bothered by it and did a search, my guess is they'd find all of that documentation and be able to see where we were coming from with some of the decisions and that may have moderated their feedback a bit.
I will also be the first person to say that there's no way that the design work I put together for the Anaconda team was perfect. Have you ever taken a drawing or painting class? If you start in with the eyes, and try to render them perfectly, then move out to the nose and the mouth and the head and the body — rendering each as accurately as you can, one-by-one — you are going to find yourself with a disproportionate and likely poorly-composed work with many smaller nicely-rendered bits. Nobody, not even the great Renaissance masters, sit down to an easel and draw a perfectly lifelike rendering of what's in front of them starting with the very first stroke. You have to start with broad strokes first, lay down the foundation for your composition, do one pass for gesture, do another pass to pick out the positions of the major body parts, another pass to hit the major shadows, do another pass... so on and so forth, until you get down to precisely-rendered, life-like details. You don't start with those details. The design we started with for Anaconda is a few passes in, but we're working with the feedback we get to make additional passes and refinements.
ML: I've hear some people advocating for the use of a separate tool for the complex task of partitioning... perhaps gparted... but that wouldn't work would it? If I understand correctly, the Fedora installer has requirements for more advanced partitioning / filesystem features that gparted does not offer... things like Linux software RAID, LVM, and various combinations of those. Is using an external tool even a viable option?
MD: Using a separate tool for partitioning would be a good idea in that, at least for the full / non-live installer, you're in a limited environment to get your work done. Partitioning is scary work, even if you really know what you're doing. Anaconda itself is a limited environment — you don't have a web browser to look up help and it's constrained in ways a full desktop is not. Anaconda handles these things because it has to, but I personally think it would be ideal if Anaconda handled installation and a lot of the complicated storage bits were handled by another tool that specialized in storage. As you point out, though, the tools that exist now don't meet the same requirements that Anaconda does, so Anaconda continues to handle storage configuration like partitioning. Anaconda is now modular, though, so the storage-handling code is now actually broken out into a separate library called blivet. Maybe at some point an external tool could be written that uses that library.
ML: Are there any upcoming changes in Anaconda in Fedora 20 that you'd like to mention?
MD: If I can get that mockup I mentioned earlier done and the team has enough time to implement it, maybe there will be a button to go to directly to custom partitioning. If not Fedora 20, hopefully Fedora 21.
ML: Is there anything I neglected to ask about that you'd like to mention?
MD: Yes, "How do you like working at Red Hat?" To which I would answer, "It is the best job in the world." Thank you for the interview, I enjoyed it and I hope it helps your readers understand a bit more about the Anaconda UI redesign.
ML: Thank you for taking the time to answer my questions.
As you may know, Fedora totally redid their Anaconda installer starting with Fedora 18. There are many reasons for it and I'll not go into that here but one perception out there in Internet land is that the partitioning section of the newer Anaconda installer is a pain to use. I must admit that when I first started using it (installing Fedora 18 alpha and beta releases), I really did not like the changes. This dislike persisted for some time until I finally got used to it. Then time passed. Fedora 19 development started, ran its course, and then Fedora 19 was released. It offered some Anaconda refinements. Now Fedora 20 is approaching its beta release and there are yet more Anaconda refinements.
Since I build my own personal remix of Fedora with the stuff I want pre-installed, I do a lot of installs... to test stuff out. I've definitely gotten used to the newer Anaconda now and I actually like the partitioner. The last time I installed Fedora 17 (to test my last remix build, it has since gone EOL) I actually felt weird using the older Anaconda. I actually prefer the newer one now.
Few people do as many installs as me... and some are still stuck in the "not liking the newer Anaconda" stage. Their main gripe seems to be that the partitioner is very confusing and somewhat broken. I disagree with them and I've been doing some troubleshooting with a couple of problem installs users were having. Turns out their problems had less to do with Anaconda and more to do with having terrible pre-existing partition layouts on their hard drives. I though it might be useful to examine two cases where I have the actual fdisk listings of their partition tables. I'll not mention the names of the users who provided them to spare them some negative attention.
Example one - Let's just jump right in. Here's an image that shows a really poor pre-existing partition table:
Here is a somewhat incomplete
fdisk -l listing for it.
Device Boot Start End Blocks Id System /dev/sda1 63 80324 40131 de Dell Utility /dev/sda2 81920 20561919 10240000 7 HPFS/NTFS/exFAT /dev/sda3 * 37459968 204937215 83738624 7 HPFS/NTFS/exFAT /dev/sda4 307337216 312578047 2620416 f W95 Ext'd (LBA) /dev/sda5 307339264 312578047 2619392 dd Unknown
That almost looks reasonable until one examines the details closely. There is a gap between the end of sda2 and the start of sda3. There is a gap between the end of sda3 and sda4. sda4 (the extended partition) is very small and as a result sda5 (a logical inside of the extended) is very small. What we have here is a bunch of free space but no way to get to it. One can NOT make any additional primary partitions. One can NOT make any additional logical partitions... and to the best of my knowledge... one can NOT make any more extended partitions. All of that free space (> 50GB) is in a virtual no-man's land.
How did this poor partition layout manifest itself in the Anaconda installer? The partitioner said there was plenty of space to install Fedora but whenever you went to actually create partitions / mount points it would give an error about there not being enough room to create said partition. Basically Anaconda was confused by the layout but really didn't have a way to communicate that the layout was unworkable. The end user is left with the impression that Anaconda is horribly broken when it was really a badly mangled pre-existing partition table that was to blame.
Example two - Here's another example of a really poor pre-existing partition layout as witnessed by the complete
fdisk -l output.
Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0008cbe0 Device Boot Start End Blocks Id System /dev/sda1 476313598 625137344 74411873+ 5 Extended /dev/sda2 16065 157765631 78874783+ 83 Linux /dev/sda3 160312635 476295119 157991242+ 83 Linux /dev/sda5 602389368 625137344 11373988+ 82 Linux swap / Solaris /dev/sda6 * 476313600 528878053 26282227 83 Linux /dev/sda7 528891993 602389304 36748656 83 Linux
I wish I had a screenshot of what that looks like inside of gparted but I don't. Just look at the start and end sectors for each partition. sda1 starts somewhere in the middle of the drive. sda2 is near the front. sda5 is after sda7. I don't think there is freespace and if an install is to be done, the user needs to reuse one or more existing partitions.
What did Anaconda do with this? The user reported that the install progress bar just hung at a very low single-digit number. The user just ended up having to power cycle after waiting entirely too long for it to finish when it wouldn't. After rebooting the install seemed to be functional but what exactly happened to make the installer get stuck is unknown. Anaconda gave no indication that there was an issue and did its best to work but obviously got confused.
How did these partition tables get mangled? - For both partition tables, I don't think any sane partitioning program would allow a user to create those partitions on purpose so you really have to ask... how did they get that way? To the best of my knowledge, both users engage in the practice of distro hopping. Distro hopping is where one is interested in using or playing with a different Linux distribution with some regularity. One of those users might be the host of a popular Linux-related podcast who reviews one or more different Linux distros every week... or not. :) But seriously, those partition tables can only be the result of multiple Linux installers, using different methods, strong-arming their way. An odd partition operation to make this distro install... and another one later... and maybe more down the line... and you get a mangled layout. Or at least that is the best explanation I've been able to come up with.
How should Anaconda respond to pre-existing unusable or sub-optimal partition layouts? - It would be nice if Anaconda could play the part of partition therapist and recognize when a user has a really bad partition table that is virtually impossible to work with... and just inform the user in a kind but clear way that they need to fix that before Fedora will install. Historically Anaconda seems to just get confused and error out... thinking that it could do something with it but failing. Can this be fixed? I'm not sure but I hope so. I certainly don't expect Anaconda to figure out methods of fixing the bad partition layouts but they do exist and a small portion of users are going to run into trouble. Luckily I've yet to see a situation where Anaconda makes the situation worse by breaking existing OS installs.
But wait, there's more - It turns out that both users had additional partition related problems.
User one has a Dell laptop that offers a special featured named DirectMedia. Go ahead. Take a little time to read that wikipedia link especially the Design Controversy portion of it. It turns out that the existence of that odd extended / locigal partition combination might just have been the result of MediaDirect... and even if they had been able to install Linux, at some point later when Windows was booted again, MediaDirect would have probably regenerated the problematic sda4/sda5 combination probably breaking any Linux install that was done. Now that takes "Made for Microsoft Windows" to a new and more scary level doesn't it? :(
User two once used dd to backup the contents of one partition to another and as a result had two partitions with the same UUID. As you will recall, one of the U's in UUID stands for unique but in this case it wasn't. Just what confusion might that lead to? They reported on a few occasions that most boots of their computer things were normal but other boots the contents of their home directory would totally change... only to change again next boot. After they figured out that they had two partitions with the same UUID it started to make more sense.
Conclusion - The point is that where there is smoke there is sometimes fire and no Linux distro installer can be a complete fire extinguisher in all situations. Some users have bad partition layouts and it would be a good idea to take that into account. Oh, how about a recommendation... boot your machine with some live media that includes gparted and get your partitions in ship-shape before installing. gparted is more battle tested for partitioning, resizing, etc than any distro's installer. Lastly, the newer Anaconada isn't so bad so get over it! :)
It was recently announced that the Raspberry Pi (RPi) has sold 1.75 million units in the 1.5 years they have been available. That is seen by most folks as a screaming success. In contrast, the One Laptop Per Child project (OLPC) has sold about twice as many OLPC units in about 6+ years... yet it is seen by some as a quasi-failure.
Target Audiences - Both projects have targeted the education market. OLPC is aimed at general education and early grades whereas the RPi is targeted at the same and older age groups specifically in computer science education.
The OLPC has been sold specifically to governments and school systems and while they dipped their toes in the consumer market with the Give 1 Get 1 programs, those efforts were not well executed and as a result only became a small fraction of their sales. The bulk of the RPi sales have been directly to the retail market. RPi is still working on educational materials and it is still unclear how well it will do within school systems. Retail sales may still help with the RPi goals but to what degree is unclear. It appears the bulk of their sales are going to hobby type projects and I'm not sure if those qualify.
Copy Cats - The hardware of both projects launched new mass-market product categories because oddly the retail and wholesale mega-corps got scared and had to introduce competing products. The netbook did quite well for a couple of years but the pricing on more traditional laptops dropped low enough to practically eliminate it. There are a large number of ARM-based RPi like single-board computers (not counting the embedded market that pre-existed) but I'm not sure that any of those will be notably successful. RPi clones are somewhat overlapped by the mini-Android clone market.
Hardware and Pricing - Both projects have had unanticipated delays in their design and production phases but they made it through. OLPC ended up being more than double their target price, which appears to have been unrealistic... while the RPi, perhaps having a closer relationship to a component manufacturer, hit their targets. The OLPC is a more complete gadget whereas the RPi requires a significant amount of hardware extras before it is usable. While it is easy to overlook the extra costs associated with the RPi, they are definitely real.
Both projects have revisited their designs coming out with newer hardware releases. The OLPC is in their fourth iteration and they completely changed CPU arches yet the outsides look exactly the same. The second RPi release doubled the RAM without a price increase... awesome.
Software - One major difference is in software. The OLPC Project designed a custom user interface and several stock educational activities on top of Linux whereas Raspberry Pi hasn't had to do as much in the way of software. Both projects have successfully relied on the communities that sprung up around them to augment the software both provide but the RPi seems to have a ways yet to go with the software for their target audience.
Roots and Expectations - Given the similarities and differences between both projects, why is one more often perceived as a greater success than the other? I think a lot has to do with the roots and expectations. One had a big name and lots of media up front and was expected to "change the world" and the other, not so much. I think that is the main reason for the perceptions but there is certainly more to both projects than such a simplified type of judgement conveys.
Unanswered questions - Here are some of the questions that come to my mind. Did I leave any out?
How well will RPi do inside of school systems?
Will RPi rev their hardware like OLPC has with major changes? If so, how will it impact manufacturing costs and pricing?
Will any of the wanna-be products be able to significantly poach users away from RPi or will RPi do that themselves with a later model?
Does the current RPi model B have such a strong mindshare that a future model may be overshadowed by it?
What future plans does the OLPC project have?
How many more OLPCs could have been sold if they had added the consumer retail market as a target and executed as well in that space as RPi has?
OLPC has taken a small foray into the consumer market by allowing their name and look be to be used by one budget Android tablet maker. How well will that do and will there be others?
How exactly do these OLPC licensed third-party projects benefit the OLPC project?
And lastly, will any of those questions ever be answered??! :)
Conclusion - In any event, I'm glad we have both projects and wish them continuing success and a long future. Keep up the great work everyone. Will there be any other projects that make it this level? I certainly hope so. We definitely need more open hardware in the market.
I saw this mentioned on the Fedora Planet. Andy Grover gives a presentation on The Linux Way and how while it is based on The Unix Way, it has been updated for a new era. The real content starts about 4 minutes into it. Enjoy!
I use CentOS quite a bit myself and I know a lot of other CentOS users. Here is a video of one of the main developers (Karanbir Singh ) within the CentOS Project explaining how the CentOS Project works and builds what it builds. Enjoy!
Anyone who has been following my computing adventures on this website for very long will probably already know I'm a big fan of remoting protocols. Ones I've used so far include SPICE, VNC, RDP, X11 redirection, X11 tunneled thru SSH, and NoMachine's NX 3.
There are two new developments in this area. The first is the recently released NoMachine NX4 and the second is x2go. I've had a chance to play with them both and what follows are my initial reactions.
NoMachine NX 4 - If you didn't notice, NoMachine finally released their NX 4 product line. I say finally because I think I saw the first "NX 4 is coming soon" blurb in the pages of Linux Journal magazine about 2.5 years ago. NoMachine has also totally redone their website for the new release. NX 4 is closed / proprietary software. They do offer a gratis download where you can have one user and you don't have to fill out any annoying forms to get to the downloads. If a single user meets your needs, you are good to go. If you want more users, pick out one of their products that meets your needs. Their commercial offerings allow for multiple users on a single host or a session broker to scale users across multiple servers.
What's new in this release? Besides moving to complete closedly software (NX 3 had GPL'ed libraries), NX 4 offers a lot of new features. The NX 3 protocol was basically an extremely efficient rejiggering of the X11 protocol and as a result, NX 3 only ran on servers that offered X11... primarily Linux. The NX 4 protocol is completely new / different and as a result they have made it multi-platform. In the past they had NX 3 client applications for Windows and Mac but not the server side. With NX 4, they now support Linux, Microsoft Windows and Mac OS X servers. So far I've only tried NX 4 on Linux but I'm sure Mac users are going to be very happy because their remote access options have been very limited.
NX 4 has gone a long way to add features that people want in a modern remoting protocol. For example, it now supports multi-media quite well even at fairly modest bandwidth limits. That isn't to say that it is magic but it does amazingly well. It supports sound and video. It has client side session recording. Files can easily be copied between client and server. I also believe client-side USB devices are supported although I have yet to try that. NX 4 has a new, modern interface that is pleasing. It is easy to use especially when you learn the config hotkey in the client (ALT+CONTROL+0). NX 4 is very scalable and can dynamically adjust to changing bandwidth conditions.
Some things I don't like: The NX 4 protocol no longer runs through SSH on port 22, as NX 3 did. NX 4 runs on port 4000... and a result I think it takes a little more effort to initially set up... mainly because anyone using a firewall will have open up a new port. If you are the one with control of the firewall that is no problem, but if not, it might take some effort. In the past, NoMachine had separate packages for the server and the client. Now there is only one package that includes both client and server... so if you want only the client, you are going to end up installing the server as well. I hope in the future they split the package in two again. I wonder if the single package is a marketing ploy or a sign that they didn't spend as much time on the packaging as they should have. At least they offer the Linux version in rpm, deb, and tar.gz formats.
Update: (25 NOV 2013) I got an email from No Machine's Gian Filippo who mentioned that they do have separate client and server packages but they are in the enterprise section. He also said that NX4 can still use ssh for transport except that it was extra work to do so and Windows and Mac users won't have sshd by default so ssh isn't the default. Again, I think this is an option in the enterprise packages.
x2go - The Fedora Project released Fedora 20 Alpha this week. Being the big Fedora fanboi that I am, I was reading about the new features in the Alpha release. Many of the new features caught my eye but the one relevant to this blog post is x2go.
x2go is based on the GPL'ed NoMachine NX 3 libraries. x2go is NOT the first project based on those... as the more well known FreeNX came first. Unfortunately the development of FreeNX stalled and the last updates seem to be from 2008. x2go appears to have picked up NX 3 ball and run with it. Not only have they modernized the code to run on contemporary systems but they have also added a number of new features. They supposedly have a session broker application that can scale connections across multiple hosts turning x2go into a more complete terminal services solution. I have only tried the simplest case of installing the server on a physical host as well as a KVM virtual machine and connecting to it from a single client. In the simple case, it works quite well. They supposedly have added sound, file sharing, and client-side USB... all running through SSH... but I haven't tried all of that just yet.
x2go is still based on X11 so the server side is not available for Microsoft Windows nor Mac OS X. They do have client applications for Windows and Mac. I tried the Windows client and it looked and worked great. x2go will be available in quite a few distributions via stock repos. Is x2go available for your preferred Linux distribution yet? I wish Fedora had x2go packages for Fedora 19 as it will be a few more months before Fedora 20 is released. I certainly hope the EPEL packagers will make x2go available for EL6 (and EL5 if possible) at some point and I expect it to be a stock package in EL7.
Overall, x2go works quite well.. and over a LAN it easily rivals SPICE... except maybe for video. I haven't had a chance to try it in lower bandwidth situations although I expect it to work quite well as NoMachine's NX 3 product line was excellent.
Conclusions - Which do I like best... NX 4 or x2go? Both have their pluses and minuses. I prefer FLOSS software but yes NX 4 has some additional capabilities that under certain conditions I might want. For example, if I wanted remote access to a Windows machine or a Mac, x2go is not an option. NX 4 is going to be a hard sell on Windows systems because Microsoft's RDP is there by default and well entrenched.
When Fedora 20 comes out and is my distro of choice, adding x2go will be a no-brainer. If it becomes available for EL, I'll use it there too. At this stage it is hard to say because I haven't tried out any of the more advanced use cases. How well does x2go scale? Which desktop environments are written well enough to accommodate multiple users? Once I've had more time with both of them I might have a more complete answer... but at this point I'm glad there are more options in remoting protocols. Which ones do you prefer?
Here's Gabe Newell from Valve / Steam talking about Gaming on Linux also from LinuxCon. Enjoy!
LinuxCon 2013 NA is this week. Here's the keynote from Linux Foundation head Jim Zemlin entitled, "The State of Linux". Enjoy.
I've been playing one form or another of electronic Mahjongg for a number of years. One of the first games I remember was Activision's Shanghai for my Atari ST back in the late 80's. In modern times I mostly play KMahjongg. GNOME has a pretty good flavor too... but since I've been using KDE for so long, I've got more time in with KMahjongg. One feature of the Atari ST version that I miss was the competitive mode that had two flavors: 1) two player, take off as many tiles as you can before you choke and hand it off to the other player, or 2) Take off one tile and pass it to the next player... or at least that is how I remember it. KDE has a second flavor of Mahjongg for online play named Kajongg but I haven't figured that out yet. Anyone played Kajongg?
One question I've been asking myself over the years though... is how good am I at Mahjongg? I'm posting this video to show a sample play session. It isn't my best game/time but it isn't bad... and I also show my top 10 times. Anyone else close to me? I challenge you to post your top times. The video has no sound. I could have put some loud trance beat behind it, but I find those videos annoying. I prefer the default tile layout (dragon?) and the traditional tile theme.
