New Prepub Request - Logos for Linux

Pre-pub request.

To settle the question of if it would be profitable to produce a copy of Libronix for the Linux / Unix operating system - even if it is a console type program, I would like to ask Mr. Bob P. if he would consider placing "Logos for Linux / Unix" on the pre-pub list for "Gathering Interest" and if sufficient interest is expressed, produce it - even if users have to subsidize the program by paying for it.

Many small netbook computers run Linux like a racehorse - very fast - and I believe in the near future that there may well be an increase in users of this operating system.

I'd like to suggest - perhaps as a beginning - to produce a stripped down version of Libronix - simply one that worked both in console and X server modes (or just console if need be) which would open up our books and search. Similar to Logos 2.0.

Perhaps the Pre-Pub would be aimed at the small linux netbooks and include the a Bible that is available in many languages. Such would be invaluable to missionaries who are involved with the OLPC http://laptop.org/en/ program.

In any event, such a listing for a pre-pub would give solid evidence to Logos management if this project would be worthwhile for them to harness their precious resources of manpower, equipment and time to this end..

Sincerely,

That's a great idea, and I'd do it if I thought there was even remotely enough interest.

But I've got a few facts that make it clear this is not yet profitable.

A) I know how much we sell to Windows users. I know how much we sell to Mac users. I know the relative market share of those platforms on the desktop, and my sales breakdown follows the industry stats. Plugging the Linux market share into this indicates Linux sales of...well, not nearly enough. And while Mac users have a reputation for spending MORE on software than Windows users, Linux users have a reputation for being Linux users because they don't like to pay for software at all. (Yeah, I know, it's because Windows is bad code, Microsoft is evil, and Apple is too cool / expensive / pretty / whatever. (Actually, why don't Linux users just become Mac users? It's Unix, there's no Bill Gates... :-) ))

I know how many lines of code we have. I know how many lines of code a programmer can port / write / debug in a day. I know what a programmer costs per day (!). I know we've never had any pre-pub, of any book or product, return enough to cover this cost.

C) The pre-pub already exists. At:

http://www.codeweavers.com/compatibility/browse/name/?app_id=321

you will find a pledging system for getting Logos Bible Software running under CrossOver. It's got 19 pledges at $1,793.90, and I'm pretty sure that I represent at least $500 of that. Get the pledges over $250,000 and we'll believe there's a viable market. And so will Codeweavers. You'll probably get it fast. :-)

D) I know we're going to let people access (most of) their Logos content via the web in the future. Linux users (and BeOS users!) will be supported here for no more investment then we'll need to support Windows and Mac, and this seems like the most cost effective solution. I'm sorry it's not ready yet.

Item D is really good to hear. It will allow access through all kinds of mobile devices that are getting more popular. Will it enable offline mode if I want to access my books without connecting to the internet through the browser interface if I have the book file and license file off-line?

I'm just going to mark this post as a favorite. Thanks Bob.

As you've stated elsewhere, WINE/Codeweavers is an option and one that I've been working at for some time - with too little result.

David J. Ring, Jr.

Bob,

Put a Logos "Pre-Pub" up for Linux version - I bet you will get a much different response.

If I'm wrong - you've wasted not much time and even less money.

I think a DOS type of program would be nice - but I guess the old Logos 2.0 version wouldn't work with the newer books - if it would it would enable lots of those little Linux netbooks to work like the eePC and MSI Wind.

Why not, Bob, put up a pre-pub - if your old Logos 2.0 code was written in some sort of language that can be recompiled easily to Linux (there are lots of compilers out there - python, C, C++, perl, ruby, etc.

If it works and you make even enough money to pay for the work it will open up a new market - the missionaries will want ALL the nice books and the parishioners would want a few books.

Then again, if the interest is few, you haven't invested more than a few electrons on your web page.

If it really kicks off, and you can make it pay - those people are happy, and it probably will open up a new market. I'm sure if you sold 50,000 copies of one book and the Linux software you'd be happy - not to mention the public relations bonus of being THE company who opened up the small Linux netbooks that are to be distributed in the 3rd world.

It sounds like a good solution.

WINE is good but it is a large program - a native program with cut down features with low memory requirements would be the way to go in my opinion.

Why not ask your head of programming if the old Logos 2.0 program can be ported or re-compiled. If it can, then some of the early Logos books can be used.

Maybe also you might have "how much would you be willing to pay for this" option to see if that would make it profitable.

Give it a try - it doesn't have to be the bells and whistles of Libronix - it can just be good old Logos 2.0 which was very fast even on Windows 3.0.

And if it doesn't get much attention - you'll have a perfect link to show us - "Hey, too few wanted it" - but untested waters may prove to be a different depth than you or I think.

Of course, I'm hoping for deep waters - but it may very well turn out to be the 1% your research says. I can eat humble pie - if I bring enough ketchup and soy sauce!

Please forgive a newbie. While I support for a Linux port and since the windows version has (apparent) problems, could an alternative be to run the Mac version through PearPC or equivalent in the meantime?

Steven Yu

Actually I quite like the idea of have a Linux Engine listed as a pre-pub, even most of the people in Linux are aware of WINE and Codeweaver project, but Logos is the company behind it, and should be the central point for all discussion in regards to the future of libronix engine.

Mark

I have always been interested in Libronix on Linux and I did not know of the WINE and Codeweaver project. Just to let you know. I like the idea of putting it up for pre pub to see who (like me) is in the woodwork that would support it.

However, according to Bob, the future lies with cloud computing and this is what he said in his point D. Therefore, it should not matter in the future.

What does matter for most of us is that we have invested thousands already in having the resources OFFLINE and those resources we would like to keep and not see our investment going up in smoke (or in the clouds). If we choose to stop investing and keep what we have, will there always be support for what we already own offlline?

Bob, I did appreciate your response very much.

Unfortunately there is a problem with making a pre-pub for a Linux version of Libronix. Pre-pub is set to gather monetary interest in a product and let Logos know when there is enough potential capital to make the project viable. Logos does not charge for the Libronix software. They only charge for the books. Thus even having 1000 people say they are interested in having a Linux version of Libronix means $0 calculable revenue for Logos. They would have to know what those users wanted to purchase. And many of those users probably already have many of the books they want.

With that said, Bob's reference to the Codeweaver site is probably the best way that Logos could offer the community the possibility of a Linux version of Libronix.

David J. Ring, Jr.

The pre-pub could include the KJV and Strong's numbers modules.

I'd pay $150 for a copy of a Linux version of this program.

I'd contribute $250 if LOGOS would buy one of the small OLPC laptops - and include a copy of the Linux LOGOS program and send it to a missionary in need of such who is working in the field. In fact, I'd give $150 plus the cost of the small Linux laptop plus airmail to the missionary - that would be better.

For years missionaries have wished for such. The small netbooks that are being released are very efficient - and can be powered by a combination of a solar panel and their internal battery for hours.

The Zip-It Internet device has great potential - it is $50 or less. See http://hunterdavis.com/archives/201#more-201

Using Codeweaver or WINE means that larger laptops have to be used.

If some of the programmers who wrote the Logos 2.0 code are still around, they might be able to port their work to Linux - these small machines could use that size program - and the Logos 2.0 code was very very fast and small - no bloat.

No one will ever know unless such a proposal is hoisted up the flagpole.

Put a price of $150 up there - make a X-Windows version of the code and a console version (even if simpler) of the code. Blind people often like console programs because they don't have to play "Pin the Mouse on the Window" by blindly moving the mouse around. With a console program (think DOS programs like WordPerfect) the commands are all key strokes. - and screen readers can read console - and do so with very little memory use.

Of course, if you're talking about a full-blown Linux desktop like Gnome (which is excellent) - their handicapped extensions managed by Orca will read and magnify everything very well.

Bob, try it - put $150 for the price - or even $200. How many will it take to justify development? 1,000 or 2,000 - that would be $400,000 at the higher numbers - I'm guessing that the work could be done and profitably (which is a good thing). Without profit, you cannot make the trip to market and we all suffer the loss.

Maybe a few more books could be added for that price - or a "gift" certificate could be included for some books. It sure would be nice to have.

I'm guessing that while Linux might have an overall market share of 1%, in this particular market, it may well be significantly more - or there might be hundreds of users who would make the leap to Linux if everything they needed was available there.

Linux has Firefox, OpenOffice which is Microsoft Office compatable, GIMP which is like Photoshop, Inkscape like Illustrator - plus there are many ARTISTIC programs in Linux which do NOT have an equal in Windows or MAC - I was amazed when I learned this.

Plus Linux still has a console - and as I said blind users and computers with low horsepower just love the console.

Why not run it up the flagpole? I don't want you to do it if you cannot make a profit - that would be suicidal - but perhaps the market is larger than you might expect because you are dealing with a niche within a niche.

As I said - I'd pay twice the price if you could give the program to a missionary organization - that would double your money flow - perhaps put that as a sub option - and if it is checked it means "twice the number of copies sold".

It doesn't cost much to put it up on pre-pub - and the idea does have its supporters. Perhaps a missionary organization will say "I'll buy 2,000 if they will run on a small Linux laptop" - who knows!

Be well,

David

Trouble is knowing whether or not there would be enough income to justify supporting it long term, with further development and maintenance releases. If the user base is small that it doesn't buy books (which is reportedly where Logos makes its real money), there won't be enough of a revenue stream to keep it going.

Anyhow, I think the CrossWeavers thing is a brilliant way to explore this.

Bobby Terhune

David,

Perhaps it would be more profitable to take your request to the different missionary boards that support the efforts of the missionaries you have a burden for. Getting a number of organizations together to suppport development could be a powerful thing.

Has anyone tried running Logos 2.0 under WINE? It just might work. Problem would be solved

David J. Ring, Jr.

Hello Michael,

I've tried Logos 2.0 under WINE - I forget the file that causes all the problems - it is an executive that is chainloaded from logos.exe - black-something comes to mind - I don't have the program in front of me.

I wonder if some sort of BOOK-SAFE can be made - but since LOGOS gives the books updates for free, I'd hate to see someone fool the BOOK-SAFE into giving permission to the reader without payment.

It certainly can be done in some way - we have to be sure that authors, coders, managers, illustrators continue to be able to learn their living. Without their gifts, we would have no beautiful books.

Some sort of BOOK-SAFE in which the reader requests to read a book. The BOOK-SAFE would have to query the license key, and send access to the reader. This part of the program would have to remain closed code because without such security, LOGOS or other publishers would be unable to provide high quality books, and pay the authors and illustrators.

But once the reader has access to the book, I don't see any problem with it being Open Source. In fact, LOGOS probably should head up the project to make sure that it has 100% compatability with the BOOK-SAFE. The reader could be used to access free ASCII and pdf files.

I think it would be to LOGOS's benefit to make the BOOK-SAFE compatable with other publisher's selected security - and they could license the BOOK-SAFE to those publishers - but LOGOS because it is involved with this program would show the other publishers that Libronix system would integrate their books into a Library that could be searched and work together.

I think the time is near when LOGOS will have to decide to do something like this - because the Google Reader will be a challenge simply because of the number of books that it will be able to read.

I think Google is planning to buy into a world-wide network - probably on the cellular frequencies - where the book can be bought by the user and downloaded immediately. LOGOS could do that also - and that's what it needs to do to complete with Cloud technologies.

However in some places in the world, there are missionaries without cell phone coverage - deep into the jungle!

One of the surprising things about the world-wide cellular network is that in remote areas, it has surpassed the traditional wired network with wooden poles and miles of copper. In densely populated areas, the converse is true: The areas are being strung with fiber optic cable - and the bandwidth is tremendous - but the cost is terrific. But if they can get everyone to subscribe to the fiber optic, they will amortize their costs. It is a good gamble for the telephone companies who already own the backbone of the Internet - now they've got the local area covered.

Also if LOGOS was involved in the open source group - they could find some very talented coders - and they could HIRE them. Of course, they'd have to do a psychological screening of them to ensure that they don't quit and then break the code publically. That would be terrible.

But you're right - there is a lot of talent out there - but it is very important to make sure that the books are secure - there are different ways of doing this which I wouldn't discuss on a public forum, but you're right it can be done - and it would make a very interesting project that I'm sure would be mutually beneficial to Libronix, in fact it may very well be the life preserver that they need to stay competitive in the publishing business that is just about to experience a radical change similar to the change from hot type to cold type (from hot forged metal lead slugs to computer generated material and computer driven printing presses).

Be well,

Pre-pub is set to gather monetary interest in a product and let Logos know when there is enough potential capital to make the project viable. Logos does not charge for the Libronix software. They only charge for the books.

That is not entirely true I am a mac user and logos charges all mac users for their engine. It could work bu the problem is one of numbers, although since the macintosh is a unix kernel perhaps the mac code could be ported more easily. But as has been posted here Linux users can run VMware and windows under it. I don;t call it an ideal solution but unless linux users are willing to pay like mac users have I wouldn't expect to see a LInux version for a few years, it has taken over 10 years to convince Logos to ma one for us. I am not saying they shouldn't do one but just want to say it could take a while.

Note: I sent Bob a CC: of the submission here by direct email as it seemed that he hadn't been able to read this thread. I made my best pitch concerning this, and he (in the email below) gave me his best answer. I'm sharing it with the other readers of this thread.

Most often the first few exchanges - or even just the first message carry most of the importance of the discussion.

I know (and hope) that he is busy producing his continued excellent product, and I thank him for the time and thought he has given to this.

I appreciate your enthusiasm, but based on our Mac porting experience, we're looking at costs between half and a million dollars to port to Linux. (Our application is very large, with millions of lines of code.)

At $150 per copy, we'd need to sell between 3 and 6 thousand copies. Moreover, we'd have to front the half million or more before we finished and were able to collect the sales.

It's possible that it'll be easier to do this once we finish our next generation Mac application, but we're still working on that.

It's also a massive distraction. We'd need to hire Linux developers (which we've never done), and we'd have to buy new equipment, etc. We'd have to hire and train customer service reps on Linux. (It's easy to find call center staff with Windows or Mac experience. Linux tends to be used by technical people with technical jobs, not customer service.)

And then this would have to be the single best selling product in our history (unlikely), and LInux users -- people who self identify as fans of "free software" -- would have to pay $150 to get it. If we made it free, like everyone would expect (the way our Windows engine is free), we'd have to sell MORE copies so we could pay book royalties and cover development costs.

Sure, we could put it on pre-pub. We could put building a rocket ship on pre-pub to. As soon as we get pre-orders for $500 million we can start building the rocket. (I'm not being ridiculous -- you probably can build a private rocket for $500 million.) The problem is, it's unlikely we have or can get enough customers to make that work, and it would be a distraction in the meantime.

At some point, if Linux continues to gain share on the desktop, we WILL survey our users on this, just as we did with the Mac. But at this point it seems like a waste of time.

(I'd like to point out that the Mac has a number of Bible software packages, proving there's a paying market. There is no paying market for Linux Bible software right now that I can tell, and, in fact, the free projects don't seem to get much help.)

Sorry!

Hey Bob.

The Linux projects don't get much love because you guys have such a vastly superior product. We go through the pain of buying Windows licenses and using VMware or whatever because we love YOUR product! We just want to give you the money, instead of Bill!

(Yes, I'd happily pay $AU300 for a Linux version if I knew I wasn't going to be buying future releases of Windows and VMware).

jcc

It seems like the problem is that they are not writing code that is very cross-platform independent. As this is observed by the current version of Logos relying so much on the MS libraries and tie into IE. In fact, if they write code that was not so Microsoft dependent, libronix will probably would have worked fine in WINE and would not have cost them so much money to port it into the MAC platform. And it's not just a matter of producing a linux version
neither. it would be ideal if they have portable code so that it can
be ported to various mobile platforms as those are becoming more popular now. Their web based solution seems to be a good step in that direction, however. I hope that they can take some people (maybe people who posted in this thread) who are not so Windows and MAC centric to give them some feedback on what direction they can go given their resources with regard to their web based solution.

But Bob's got a point, I think if we can go over and convince Bibleworks or Accordance to produce a linux version, Logos will probably take the linux option more seriously. But right now, I don't think we can convince any of them to produce a linux version. Having said that, I'd be willing to donate more than $150 for the cause. (And we really have to say "donate" here, because that's more of the linux mentality--they are more than willing to donate than Mac/Win users to contribute to the spread the usage of linux--whether they want free software or not.

I came to this post due to a search for Linux after being wowed by the new Motorola phone and tablet XIOOM at the 2011 CES in Las Vegas. The Atrix is running a Linux based system when it is docked to the "laptop" docking station. As we keep looking to simplify our lives with less gadgets, this is a very promising platform. It is my hope this reply post is not on a stream that is too old to pay attention to. I have been looking at the iPad, and waiting for the gen 2. As the market expands, the offerings truly benefit us the consumer. As a pastor I cannot think of anything more promisingly beneficial than the Motorola platform for all my tech needs. I am waiting with baited breath to see how this shakes out. It is my hope it does so well and that LOGOS is on the cutting edge as always. I truly am a daily LOGOS user, and am making my decisions about my consumer needs based upon availability. Thank you for all your work, and I continue to look forward to a life-long relationship with LOGOS.

David J. Ring, Jr.

I guess the biggest problem is that for some reason Linux doesn't do encrypted media very well - but in Logos the media isn't encrypted. It is the license key and that engine. I see no reason why Logos programmers can't make that bulletproof.

By the way Linux is bulletproof. I never have problems with Ubuntu or Debian. It runs for days and days and days without freezing up. I can do everything I can with Windows and even more - except for borrowing audio books that have digital rights management on them.

There is hope though, Logos is supposedly working on putting all our books on a remote computer and having any platform access them. Hopefully this will also allow the remote missionary to get his books when he has Internet and to access them forever after.

My other alternative is going Mac - which is also Unix based. But if I bought Mac, I'd have less money to spend on books from Logos :-)

Almost 15 months later, pledges have increased to 21 with total of $ 2,357.90 - appears Linux market lacks viability.

With free virtualization (e.g. Oracle VirtualBox, VMWare Server) for Linux that can run Windows as a guest operating system (only need to obtain a valid Windows license that includes virtualization use). Optionally, can custom install bare-bones Windows - only need stuff to run Logos 4.

Logos subscription possibility: cloud based virtual Windows servers - remotely access Logos Library - maybe integrated with Proclaim.

Almost 15 months later, pledges have increased to 21 with total of $ 2,357.90 - appears Linux market lacks viability.

I have always been an advocate for Logos being on Linux but I have never made a pledge. To be honest, I could not figure out the website until now and even now, while I know how to make a pledge, I dont know what I am making a pledge to. I dont understand the technicalities of getting Logos on Linux. I dont think it is wrong to ask and have this website Bob created, but the pledges there I would highly suspect does not represent the lack of a market. It just represents the lack of desire to understand the technical difficulties of the project.

Why not put the project on the community price page with a link to this original website? And ask for pledges there? Why not create a logos for Linux forum and see what develops from that? I think the answers to these questions is simply due to the lack of interest LOGOS has in the project. And in the current user base, it is obvious that most do not use or care for linux. It is an untapped market.

Logos should think about creating variations to their product: A product for homeschoolers...one for women, one for singles, one for those only interested in accessing a library on their phone and one that is interested in a basic program that would run on Linux. Why not create a FREE BASIC PACKAGE consisting of a few Bibles, a few resources....that can be access simply by creating a free account? Do you not think it wont bring in sales?

A pledge? I have already spent too much on Logos. What does a pledge mean? I already have Logos on windows. If Logos for Linux was developed, I suppose I would have to repurchase the product...and that wont happen. I wonder what would happen if I switched from a PC to an Apple...would I be required to purchase Logos for Apple? I would not do it beyond some kind of small, token administrative fee to make the switch. And the same with Linux.

TCBlack

This is not a Logos site, it's a codeweavers site (the makers/originators/business side of WINE the Windows Compatability Layer for Linux.

What you're pledging is to pay the WINE / Crossover developers once they've made it possible to run Logos on Linux via WINE/Crossover.

Why not put the project on the community price page with a link to this original website? And ask for pledges there?

Since one is a site belonging to the Crossover people and not a Logos site it wouldn't work like that.

Why not create a logos for Linux forum and see what develops from that? I think the answers to these questions is simply due to the lack of interest LOGOS has in the project

Contrary to your experience IMHO it is due to the lack of viability of the project. It takes major cash to develop a platform and no matter what numbers you think Linux has in installed desktop's it's not big enough to support a linux port (yet).

Why not create a FREE BASIC PACKAGE consisting of a few Bibles, a few resources....that can be access simply by creating a free account? Do you not think it wont bring in sales?

They do, sort of. First there is biblia.com which has that capacity and then there's the freebies on the site all linked here:

Want Libronix for FREE? | http://www.stilltruth.com/2006/want_libronix_free

And here: http://wiki.logos.com/Free_Logos_Books

A pledge? I have already spent too much on Logos. What does a pledge mean?

Bob's quoted quote above states it pretty clearly: " a pledging system for getting Logos Bible Software running under CrossOver"

Keep Smiling 4 Jesus :)

... and one that is interested in a basic program that would run on Linux.

Initial challenge is porting Logos display engine to work on a different platform, a very non-trivial task. Initial Logos for Mac version took several years; lacked many capabilities of Libronix 3 (bit more than a book reader). For Logos 4, Mac and PC share .Net code base with Graphical User Interface (GUI) coded for each platform; current Beta nearing feature parity exposure on Mac. Wiki page has Logos 4 Mac release history => http://wiki.logos.com/Mac_Release_Notes_and_History

To port Logos 4 user interface for native Linux use, anticipating over 16 months of programming effort since Linux does not have Windows Presentation Foundation (WPF) nor Apple's GUI. Linux also has many desktop managers: Gnome, KDE, Xfce, LXDE - notice Ubuntu has many distribution flavors.

Mono project has no plans to implement WPF => http://www.mono-project.com/WPF (lack of demand)

Microsoft forum discusses running WPF application on linux => http://social.msdn.microsoft.com/Forums/en/wpf/thread/0a4c924d-ef24-45a9-a552-6d58e5578e3a (refers to CodeWeavers for WINE - or change application code to use SilverLight and MoonLight)

On linux, can use Biblia web site to access Logos library => http://biblia.com/ or run free virtualization manager (with non-free Microsoft license) to use Logos 4.

I wonder what would happen if I switched from a PC to an Apple...would I be required to purchase Logos for Apple?

No - a Logos user can freely use a variety of electronic devices: Mac, PC, iPhone, iPad, & Web to access personal library => http://www.logos.com/apps (Android under development)

Wiki page has Copy Logos 4 Resources to Mac OS X => http://wiki.logos.com/Quick_Installation_onto_Multiple_Macs#Copy_Logos_4_Resources_to_Mac_OS_X (have option to avoid redownloading all Logos resources)

By the way, Logos for Mac 1 initially had $ 59.95 cross grade cost (or included with package upgrade); now Logos for Mac 1.2.2 engine is free => http://www.logos.com/product/4504/logos-bible-software-for-mac-122
