Is it reliable? Can we trust the journal to work and not loose anything in, say, two years time, even after upgrades?
You've descended into the stage of a ridiculous argument, Carlos.
I don't think so. A binary store is prone to breakage, it has happened. If you think that way, I'll think then that you are a zealot that negates any possible problem.
It is a reasonable question. Will I be able to read it in 2 years time, in any machine
I say again: You've descended into the stage of a ridiculous argument, Carlos The moment you start saying "any machine" you bring in a gunnysack of things like transmission protocols and that means the possibility of transmission errors, which I've touched on before. Different machine architectures, byte ordering and more. The belief that text or rather ACII-7 is a cure for this is misguided. that's why we have hamming codes, Reed-Sullivan codes, even for thins that we think of as plain text. The suite we refer to as "TCP Architecture" deal with the byte ordering problem a long time ago. We have as reliable binary transmission as we choose to pay for, as evidenced by downloading of DVDs or network based installs. We have transmission between machines of different architecture, word size, byte ordering. I can download the image for a RasberryPi that runs a version of Linux on a ARM with a 32 bit architecture on an old 16-bit Wndows/95 PC and burn it onto a card that's on a carrier plugged into a USB2 socket all quite compatibly. This isn't the 1960s. The really issue isn't the data or even the program, its the hardware. I have UNIX V6 and V7 magnetic tapes that were written with TAR. I _could_ read that data and run those programs, if I had a tape unit and PDP-11. The problem isn't the program, modern TAR can still read those old tapes. The problem is having the hardware to do anything with it. Oh, there's one exception to this: its legal and involves Digital Rights Management. "Will I be able to read those ebooks I bought in two years time?" is a realistic question, but it is of a very different nature.
