Idea for dynamic #QRcode generator

I don’t know if maybe this exist yet. The idea is to have an application that displays an every changing QR code (like the program “watch”). For example this could be:

  • A clock. So the qr code contains the time with seconds
  • location information
  • temperature and other data

21:23

A simpler solution sure is to have an URI which has all the information. But wouldn’t it be nicer to have the information already without internet connection.

Other solution would be to create a bell or a key. So every time somebody scans the code it opens a code that only somebody that stands before the code/door can see. So something knows, that somebody is really standing in front of the door. So you know that you might want to open the door for them, either automatically or you go and open it for them because you get a message from an IM.

The simples form to experiment would be a program that takes any input and displays it immediately. That would not even need to know qr code. But an image viewer might be too slow. If this program already exist, please let me know. I am not a programmer, but would like to see it. ūüėČ

GNOMEs Git

I never understood, why GNOME switched to yet another client/server based revision control (SVN) back then. But who was I to tell them that much more is possible. I aint the coder.

Anyway if I reas this from the new F-Spot:

This is the first release where we all used Git and it has massively paid off. Contributions are flowing in at a massive rate, from lots of people. See for yourself on Gitorious. Now that the release is out, it’s time to go over merge requests. It’s hard to keep up with them.

… I am happy that they did indeed switch to a distributed mechanism. Especially because it has always been hard to get any write access to some archives at GNOME. So it is going to be interesting what other effects this might have in the near future if people get comfortable with the new development style. Thumbs up!

GNOME: Oh dear, here they come again

I was hopeful to see some major changes in GNOME Topaz (3.0). But now I have quickly viewed the discussions on the marketing list. Especially those threads:

  1. GNOME Marketing Strategy (Was Audiences), Paul Cutler
  2. GNOME 3.0 slogans, Michael Hasselmann

PLEASE DONT (do it again)

Dont waste your time thinking again about target audiences and slogans. Some say the real target audience are distributions. But distributions care for whatever their users care. You have users – a desktop is something universal.

It doesnt work that way, that a handful of coders and other geeks randomly gather virtually and every 6 months think about some new marketing stuff. The GNOME 3.0 goals were some good direction. The problem now is to get this ideas done. I dont think GNOME will be able to do it all in one step. The problems and solutions are on the table, already. There are GNOME users – you need to communicate with them. Dont let such stuff happen like Ubuntu did with the FUSA applet.

Those discussions are fruitless and have been talked about every once in a while. They never led to anywhere. This is partly because GNOME is controlled by the coders and some major corporations like Nokia, Canonical, Red Hat or Novell, who do finance some projects and pay some high profile developers. So those two groups do set the agenda. GNOME does not and will not have any marketing of its own. It does have some accidental marketing, but this is never tough through. Who should deliver such messages? If any slogan is chosen, you really think any distributor cares about slogans?

In the past marketing has been called propaganda. Its a matter to manipulate the human mind Рits neither a development model nor an organizational model.  GNOMEs organization is not very well stuffed. There is not a lot of money and there are only a handful of people doing stuff. he GNOME Board does not have a lot of power and the developers not necessrily listen to what they say. Even less is true for the GNOME marketing team. No developer really cares about what they think or write. Fact.

I think from the birth GNOME tries to be user focused, but it still struggles with this goal and if people draw a picture of GNOME the users still do not appear. Developers are important, but without the users, nobody would use the software. And GNOME is unlike OpenBSD not a project which is mainly used only by experts, but very broadly.  But this is not reflected in the development proces. I think the best thing would be to integrate the users more into development decisions. The answer is not to let some geeks define goals for the users. The users have to do that themselves. The only possibility to give feedback is the GNOME Bugzilla. But this is mostly also not very user friendly. There is no option for users to give simple feedback. A user submitting a bug report often gets a reply to try out alpha or beta versions of the software package. This cant be true! Those geeks are just way too far away of genera users to be able to feel what those might want ot need. Even worse: Why should any developer be motivated to solve any issue a user has?

tag based working ? 1 ?

The more I do with TAGS in blogs and in microblogging and with bookmarks the more I think this could be a way to work with a lot more.

One problem we face when working with keywords is the selection of keywords. We have many different systems of keywords – like for photo management or music categorization. Also as I say “Categories” – categories are keywords/TAGS, arent they?

I know they are not REALLY. But I am reminded on the massive discussion about backlinks vs. categories in wikis.

A CATEGORY is something big …. TAGS are some small notes in one word attached to a thingy – an object. Maybe a photo, maybe an article.

Objects we do from programming. TAGS are or should be attributes to those objects.

NOW… I guess most TAGS should make sense for every object. or MOST.

TAGS are also a common knowledge. The act of tagging is important, too. On blogs like on wordpress we might get hints how to tag an article.

But how about a software that suggests to us a tag after we wrote an article? Like this one. I could assume that my article does contain some words more often. If we remove those words like “the” or does” or “wrote”we might get nowns primarily or also attributes or¬† adjectives.

Tags could be interrelated. This is why some web software offers popular tags. Many desktop applications still do not import the knowledge of the web.

Tagging means also that there is mostly more than one way to tag virtual objects. There always will be. Also every human will tell a story differently. The divergence is not a problem but is part of the ESSENCE of communication. And what are TAGS other than commnication.

If you write a blog you tell others what you think it is you are talking about. Others might think differently. Some Web2.0 software offers you the ability to add tags to foreign objects that are than publicly visible. Tags soemtimes reflect your own perception – but maybe more often you try to be smart and try to catch the peoples eyes by throwing TAGS at THEM to make you picture or article more visible. But you wont try to choose as many tags as you can imagine. This could be one method to gather attention but it would also be stupid. Like if you want to sell a product it is not recommended to promise EVERYTHING.

Google does not really honor keywords that much because it is a weak concept for public content. it becomes stronger when people vote on the popularity. But not always does a greater popularity of an article indicate that it fits one of the tags best!

So what do we need? I think maybe we would need some kind of TAG service that is spreading over different subjects and allows people to talk about tagging and follow different taggings strategies. Like Wikia Search did allow users to vote on what search results are nicer – but you cant just allow anybody to vote on anything if the end result should be smart.

Or better – its ok to allow anybody to do anything – but you then should also allow the user to select which choices she thinks are smart. Tagging should be like we talk to our friends and neighbours about where to buy or to let repair. We may come to the conclusion that some of our friends have a better idea where to buy good products than others. And we will turn to them more often when it comes to buying.

Same may be true for personal matters. The one who may know mich about buying might be dumb when it comes to personal relations – and somebody else may have a good advice for you … tagging solutions.

We now often see voting systems on Amazon and elsewhere – but they often are not very sufficient and also are corruptable.

I also think when it comes to work on the computer tagging could be cool, if the computer would have a fuzzy way to recall our choices.

I think about saving an image would not mean to select a file location – but rather to tag it – in the same manner we do it after uploading to a photo sharing site like Flickr. I think it many ways the idea of the online desktops is not that bad – but in another way. The interesting part should not be to integrate Flickr or Myspace better in our desktop – but to give the user more world knowledge in his day-to-day applications. We get some – like we can let last.fm player play our favourite music (which works more or less well) and also we might get some categorisation for our music albums that we import in our desktop via CDDB databases. But this is mostly just added feature or plugin and not something deeply integrated.

Or think about the work on the desktop -like I want to do some work with vector graphics and Inkscape editor (sort of Adobe Illustrator clone). I then want to learn about how I should act – but maybe also want to talk to people about how to use it.

Today people either use the provided help from installed manuals, or they search the web – or forums, wikis, … and maybe enter an IRC chat. And then they pose the same questions all over again – even if they have read the aqpplications FAQ. What might be interesting is if I enter the question I have inside the applications – maybe also by pointing to the section I am working on – and then I can get help documents as well als forums posts or the possibility to chat directly via instant messaging with other users who are currently working on inkscape and might be willing to help.

There used to be a service Qunu (which seems to be unaccessible fpr some months now?) which organized instant messaging interaction. You could define some tags where you think you were smart and people searching for that tag could find you and contact you directly. What about when I am using an application I could register and with this process tell my knowledge level – and then if other users work on a project with “my” application I can read their questions like in the groups of Laconica – and then even decide to interact directly and maybe not publicly. It would also be possible to not only interact by word but also by action. Some applications like Gobby, Inkscape or Abiword have been working on the ability to work on shared documents online.

And when you save – maybe you tag something as public. Epilicious is a delicio.us bookmark exchanger. A bookmark you wanted to share you tagged with “epilicious” also. And maybe just the public tagging will save the object online. Or like on upcoming.org – you can send an event to a group. People who follow that group get a notice about this new event.

I really think that this is the future computer interaction. Window managers like wmii allow you to tag an application to reside in one specific desktop window.

Essentially all computer work is about organizing. In some way if you print this is also some kind of organizing. Its an export. F-Spot uses “export” for photos who are uploaded to Flickr. In this case I think it is not good to name that an export – it is in the old sense – but in a new sense it is another saving location.

We will see a lot more virtualisation of webspace and stuff. Some people might even not use any local hard disk any more. But they still need a place where they save data like addresses.

This does not mean that we will not need locations. I think the Plan9 way was very good – to integrate all necessary location information in one file system. A completely different question is if we would need to show the location to the users or if that wouldnt rather confuse them?

So maybe lets create a tags based desktop?

Comments welcome.

Fedora Community

Max Spevack hold a talk about the Fedora Community on 2009 FOSDEM. Which I suggest you listen first before reading on:

Essentially I think Max grabbed the “Community” at the wrong handle. He elaborated a lot about how Red Hat and Fedora¬† work together and ow they enable people to build uppon the tools that Fedora has invented. Thats all very nice, especially for Red hat. In the last years Fedora often has stated that they do not interfere at all with Ubuntu. This always comes up when people compare the popular success of Fedora to Ubuntu.

Fedora is very developer centric. What Fedora is missing some warmth – some more “family” feeling. Do people feel comfortable? Fedora is also a big testbed for Red Hat – it can look what technologies work or are popular – and which are not. That makes Fedora often bleeding edge – more than a general user might often want. Also the support cycle is much shorter than on Ubuntu. So Fedora is not really a distro you would want to plant on your organisations desktops or servers. You will be forced to update quite often. Fedora moves fast. But thats getting offtopic from the community.

Fact is that trough the developer centricity leads to make the barrier for non-developers harder. One thing is what I already have pointed out in another post is the fact that even when editing the wiki you will have to sign some papers.

My view is that it is very important that the connection between general users and developers is open and flowing. Fedoras style is more a either you are a part of us or you are not.

On April 23rd I will organize my first Ubuntu  Release Party in my hometown. Why not for Fedora? Because essentially also on marketing Fedora INVENTED barriers and  created the Ambassador program, which I interpret as a means to professionalise the marketing efforts. And to make sure that people talk about the right things.

The problem here is that this turns of a lot of general users who are totally capable to talk about Fedora and show people how cool it is and what to do with it. Fedoras problem is that technically it is slightly ahead – but not years, but rather months – and that this alone does not attract people.

From all the talk I can not really see to what audience Fedora is talking. I would say Fedora is for people who want a fairly new Linux as a build platform and do live and like the Red Hat/ Fedora world. So you can use Fedora to develop an application that will work on future versions of Red Hat. Fedora also contributes a lot upstream and so allows work to be transfered outside Red Hat and Fedora.

So in the end that makes Fedora not very attractive neither for general users nor for company desktops – besides being the testbed for Red Hat. Fedora does not seem to have an autonomous agenda and depends highly on Red Hats decision. it does not make much sense for self-employed Linux folks to base their installments on Fedora nor does it make sense for the typical grandpa.

Some people at Fedora might agree and would define Community as this: Developer Community. The problem is that this also means that general users will not participate as whole heartedly as they do (for example at Ubuntu). And to make it clear: Thats a concious decision of Fedora – everything from development, contribution to marketing is organized in a hierarchical way that DOES allow everybody to start contributing but in fact turns a lot of people of.

In my hometown I have not met one guy who uses Fedora. Many early Linux users did use SuSE – and if they were dissatisfied they switched to Ubuntu – and then there is the Debian, Gentoo and FreeBSD crowd. This means nobody ever sees Fedora, this means nobody ever sees Red Hat. If this is a concious business model it is not working here.

What is Fedora missing? I think as a start it should be encouraged to talk about fedora even if you are not an official Fedora Ambassador. Give people something to work with, encourage them to make  Fedora their own. I also had the experience that nobody was willing to give a speak about Fedora at our local Linux conference Рactually nobody even answered my plea. But it should be the other way around. Fedora Ambassadors should go out actively and seek for the possibility to show Fedora. And here is also the problem Рif only Ambassadors do it, Fedora will be shown in fewer places.

So I think the whole Fedora eco system has a problem and thats why Ubuntu is so much ahead in popularity. And I dont believe you guys that you wouldnt love it if people would adopt  Fedora as much. Technically Fedora is much better than ubuntu, its the better product Рbut you very miuch have given up the popularity contest, which is sad. Even OpenSuse is doing more in this regard and it shows slowly.

I dont know who does the strategies at Fedora. And maybe you guys are satisfied with the status. But what I think is that in the longterm Fedora will be marginalized, especially when OpenSuse as another RPM based distribution is gaining more ground.

Thats it for now.

Another Online Desktop Idea

GNOME has its vision of what a online desktop should be. I have another. The idea is to find a replacement for:

  • VPN network access
  • XDMCP graphical logins
  • SSH logins
  • etc.

My idea – and I am sure I am not the only one having it is to have rather a local login to a desktop – but then be able to fetch some common settings from a central server – and maybe also some data.

I will explain a possible session:

First you have a plain desktop like a GNOME desktop. You might want to use the settings of your central account. Then you can do this by clicking on a link. You can type in your password and you will get all the settings you use. By that I mean things like IMAP account, bookmarks, Jabber account,… maybe also desktop settings loudness settings, messaging preferences – and maybe not some location specific settings like your proxy. Maybe you can register your location or rather choose it to by a dynamic location (because you use a public WLAN with some more secure settings and with different IP addresses).

On a second session  login  the settings will be downloaded and the environment of the desktop will change. Potentially this settings could be accessed from a central GCONFD which runs as root as a daemon instead of per session. Maybe this would also allow to tunnel some traffic through the server that has this GCONFD running.

So what this does NOT is:

  • It does not provide any secure connection like SSH or a real login to a server.
  • It does not provide a login to GDM through XDMCP
  • It does not provide any access to a VPN

It rather provides:

  • Information that a user has saved
  • Themes, Looks and other environment definitions
  • Maybe also acces to data if this is wanted. So if the user saves the data on a central server this desktop could offer some ways to access (via VPN, SSH, XDMCP,…). The ways that are offered could depend on the configuration of the GCONFD and on how the user defines access to his desktop.
  • It could also offer different VIEWS – so coming back to former ideas I offered here in my blog – So I as a user could define a simplified, lightweight profile for my notebook when I am on the move or for mobile devices. These views could also maybe be shared anonymized or personalized via Email, Jabber, etc. – so that they could be downloaded, installed, executed and used.
  • A way to print something from anywhere in the world to a printer of your choice.

For privacy concerns the user should be given some options to anonymize his shared views Рor be warned if the connection is not encrypted or secure enough. These views could maybe also include many different desktops in one Рso like you import a HOME view and a OFFICE view Рand can switch between them like today with the screens in the GNOME panel. So that would be useful not only while traveling but also handling different usages. Users need different environments. One main problem people have is that their computer tend to mix all kinds of usages Рso maybe somebody is working, has some private usages and also is active in an organization. Today people sort data and information by creating folders. But the number of folders is steadily growing Рand often you  only need one or two folders if you want to work on one subject. The other 500 folders are useless in this moment.

All those problems are neither targeted by todays desktop nor by GNOMEs online desktop vision which really just tries to integrate big websites into your desktop. I wish some of those visions could become true. Right now all desktops are much too conservative. I think maybe Plan 9 has done the groundwork for such an idea (representing all data in folders and files)

In need of a major new GNOME panel

I suggest that people start working on an alternative GNOME panel now. I have seen some suggestions on a GNOME wiki page, but I think most directions are very wrong. Like what you see here:

Essentially these are imitations of the fancy Mac panel. But I think that the Max panel does not give us anything cool as well as the things AWN an Kiba dock do. Look at this video: At one point it shows how to play volleyball with the icons. How stupid is that? I mean cool. Or better: I don’t care!

First of all I still do like the text menus, because you can access a lot of applications and settings without going through a lot of folders and sub folders. But I have some major problems with the panel:

  1. You can fix the position of a panel. but when I plugin in my digital projector the panel moves to the other display (on the right). How can this be called a fixed position?
  2. When the size of the panel changes the position of the fixed icons changes too. I have to resortmany icons after I have dettached my projector display. How fixed are thise positions, then?
  3. So it is impossible to configure one monitor display to show exactly the same things on each occasion. This comes from all the dynamic configuration. At least thats true for Ubuntu. Its like you always plug in a new display which you have never attached before and also like it would make any sense that the panel should never be on the main  display but always on the external display.
  4. You can also not configure to have a second panel which is bound to one display

These are only some of my new points. Here is what I desperately need:

  1. A panel which is much less customizable and dynamic. Because everything that can change results in random results or I have configure or reconfigure the panel. From my view the panel never moved to the point of the rest of GNOME. You can do nearly everything with the panel which does not make any sense.
  2. I suggest that new work goes to a new panel which can be a replacement of the old panel. Maybe one can reuse some of the old code but the essentials should be very different.
  3. I think one very important thing is that screen/display configuration and the panel should be one thing.
  4. Have the ability that the screens (1-4 or so) can be linked to specific displays, so lets say if I have two screens one is the major screen of my notebook (screen 1 on the left) – and the other screen has a different screen size (screen 2 on the right) and is configured for my projector display (which is a 16:9)
  5. If I attach a display and configure the contents, the panel, etc. these settings should be saved for this screen and display so that I get these back once I plugin in that display again. The content (desktop icons) of a display could also be available if this display is detached. Then screen 2 should be reconfigured to a single screen mode.
  6. Essentially if you want to give a presentation you will want perfect control of what the presentation screen looks like and what appears there. If you never know what happens a GNOME desktop can not be used for such a purpose. The frustrating thing is that things rather seem to get worse. I really think about switching Linux distribution because the dynamic screen configuration is really awful. I remember Fedora had a “system-config-display” which worked more relliable. I still dont know why this is not used upstream. Maybe some people think that this dynamic thing is actually good. Maybe it would be if it would work – but till then please keep this as an experimental feature in SVN and do not put it on Ubuntu LTS! grrr. sorry I had to go through a lot of troubles and still do because of this thing.
  7. I would dump all current panel applets because most of them are useless. Instead I would suggest to give a panel some functions like displaying time and weather. Or maybe for advanced users allow them to put a content on the panel which they can insert from script output. Like if I put on the hardware sensor monitor applet I get 10 or more icons on my panel and then have to find out which is the right important temperature. Instead of an applet a user should have a setting where he can enable the display of a temperature and hopefully GNOME can show the right one or give the user the opportunity to to enable the right sensor.
  8. Then there should be an area where the panel displays the icons of the most used user applications. Maybe allow the user to say which applications should never appear. But this would give the user a perfect access to the most used apps without forcing him to put them there. Why should he?
  9. As stated before I think it would be most intelligent if the panel itself is the interface to configure display. So when you add a new screen/display you can choose which panel you want (like no panel, copy major display panel, standard clean panel,…) And maybe have the ability to close/remove a screen with a closing the panel like you do it with tabs in browsers.
  10. I also think organizing screens and applications via the panel should be more intelligent. The tabbed window managers (wmii,dwm,…) invented the ability to group applications – so lets say you can configure a graphic screen and gimp, inkscape, blender,… all open on this one – or you have a mail screen where you work with email. Those screen layouts or definitions could be saved, so that you may have a more general notebook screen but if you go to work and attach your notebook to a large LCD display graphical applications will appear there. Today its rather primitive like you have screens 1-4 and have to move an application there manually on each occasion. Also handling screens should be easy like handling tabulators on a browser. Maybe in the future you may even be able to drag and drop a screen to a remote computer and then the other computer can work or see what you are working on or you can share a screen.

So I think most that is discussed so far on GNOME is nothing more that re-engineering of what Apple did and maybe spice it up a little. Only interesting page on the wiki that I saw was that about GroupBasedWindowManagement. I a pessimistic about GNOME or KDE being more creative in the future. Unfortunately the tabbed window managers still have problems with many applications and often still require some manual configuration. I really think maybe soem new project should try to do things better without repeating past mistakes. Like have less dependencies, so that operating systems like OpenBSD will also follow the development.
