    Do you remember your physics courses and the old story about the number of calories to convert water to ice? Converting humidity to snow must mean that you take heat out so that the snow forms, and then we need to dispose of the warmth. Ergo, the ice caps receive part of that warmth.

    At least, that is what I conjecture. I also think that much of global warming is caused by deforestation. Trees are great for acting as wind-brakes. Trees may be stopping warm air from moving towards the polar caps. They also must help with cooling via evaporation from the leaves.

    ===
    should the hardware vendor provide a second level external software bios that the secure boot bios loads? This latter bios would contain the user managed security keys to allow the starting of any operating system. This bios, once its signature is validated would take over from the rom/eprom bios.

    That would solve the problem of permitting any user operating system to boot. The risk, if there is one, is that your selected operating system may contaminate another operating system.

    Coding brings a skill that is more than doing mechanical thinking. A programmer's mind is receiving training in logical and sequential problem solving. He knows to have an initialization, session, followed by a processing session and to produce results.

    This structured learning by students serves them well. They are not lost when faced with a homework or research project. The thinking processes with programming carry over to solving challenges as teenagers and adults.

    And in the USA and Canada, with absolute concentration on deficit reduction, the students are not getting what they need. It is "Slip, sliding away".

    Computer programming teaches logic and rules. Learning a second language does that as well. For North American Students, I believe that children should start a second language, preferably Spanish, as early as kindergarten. Most kids can substitute a second language for programming.

    (Why Spanish). There are 37.5 million Hispanics in the USA. Add to this number the populations of Mexico, Puerto-Rico, Cuba, Central and South America, and with 350 million Spanish speaking people, it makes good sense. In the next decade, much more trade will be a north-south hemisphere exchange, and it makes sense to be fluent and ready. Most of the Latinos are schooled with English as a second language.

The children learn "good French" well. In grade 4, they are switched to 50-50 French / English, and by grade eleven, 70% English in the courses. The kids speak, read, write both languages fluently.

  12. Re:backup orthogonal to encryption on Ask Slashdot: Simplifying Encryption and Backup? · · Score: 1

    Aka: you are doing it wrong. First think of backup: you have a machine, and you copy its contents to another drive. Ok. Easy. Now take a breath, and use OTFE for the original hard disk, and now add OTFE for the external drive/media. There. The backup has NOTHING to do with encryption. If you have forced yourself into a backup solution which requires encryption integration to the point that it only restores to a specific hardware, you are failing hard time, precisely for the reason backups are for when you don't have the original hardware.

    Again, separate backup from encryption. I mean, next you will want an integrated internet/remote backup and you will cry us a river? Compartimentalize each function and then you can mix them freely.

    If you are interested, here is an explanation of software I wrote to address encrypted backups or file transmissions.
    I wrpte a Linux based encryption software that I developed for backup and file transfers as well as for database field encryption. The concept is simple.

    I maintain a table of keys (16 "8 byte" keys). I am using 3DES, but the concept is similar if you wish to use AES for encryption.

    In the header of the encrypted file, maintain some signature to say it is your encrypted file. Then in four successive nibbles, each nibble serving as an index (counting from zero) to indicate the sequence of table entries that are needed to build the 3DES encryption/decryption/encryption keys. If using AES, the concatenation of the three (or 4 keys, if you want higher encryption sizes), creates the key to encrypt or decrypt. I also use cypher block chaining(CBC). CBC does mask repeat patterns. Here again, the CBC initial field can be an extract from another table. My file header looks like this "[Leslie]23F5" representing indexes 2,3,15 with cbc from entry 5 of another table. (counting from zero). The CBC field is from a different 16x9 table. CRC or md5sum can be used to ensure no transmission errors occurred. I was even considering basic ECC encoding to allow for correcting single bit errors. Now what is necessary is to keep the keytable copy in a "wallet" or TPM file. I also have an algorithm to generate the 16x8 hex table that is used for these keys. (Basically, no encryption table row is a duplicate of another row). I use 3DES because it is non algorithmic, and its a very lengthy trail and error exercise to determine the keys and it is used with or without the CBC. By the way, without a debugger, even I do not know how the keys are constructed or their key values. Once encryption or decryption has completed, I overwrite the control tables.

    AES execution is built into the Intel hardware, and therefore speeds up the process of encrypting. It also speeds up the discovering of the encryption keys. That is why I discarded using AES. A second reason was that I wanted the smallest field that I could encrypt to be 8 characters.
    One use was to provide clients with the software. Each client would receive his encryption keys. His files, when received at a host server is re-encrypted to the internal set of keys in use by the institution. The architecture is to insure that internal employees could not transfer customer A's files to customer B or internal files to other than the encryption server. Customer A would be able to decrypt his files but noother. As well, critical database fields in multiples of 8 bytes can be encrypted.

    PGP was discarded as my way to use encryption, because of the way many financial institutions work. For example, a bank with 15000 customers is often required to store several weeks or generations of reports that a client may wish to receive.

    If the customer loses his system and his private key, the bank would have to rerun the applications that were used to generate those reports in order to recreate them, with the exercise to generate new client public/private keys and re-encrypt files to the new keys. This would be and is horribly expensive, as a client population of 15000, always
