    The article section you referenced does only say things about the involvement in humans being used as test subjects and the involvement of the Bayer company in the holocaust.

    And this was only possible because people were seen as being of less worth than others - as so called "Untermenschen" (-> sub-humans). And these people could to anything with those so called "Untermenschen", and gain profit.

    However you missed the initial point that the holocaust was only to gain money from robbing jews of their possession, the robbing was a by-product, the basic intend was to wipe out the jewish population, and not to forget all other "races" that the Nazis deemed not life-worthy - mostly the population of eastern europe.

  9. Re:I disagree on Germany Cracks Down On Illegal Speech On Social Media. (smh.com.au) · · Score: 1

    No that's wrong, you do show the cause and effect in a wrong way.

    robbing possession
    As it is true that the Nazis robbed or coerced jewish people - those that were able to leave the country or those getting slaughtered - off their possession, the basic cause for the prosecution was a racistic - racial ideology - view on humans, their physiognomic properties and their suggested different worth for society.

    pseudo-scientific racial "theory"
    This pseudo-scientific racial theory/ideology, in contrast to the "normal" anti-semitism that the church - protestant and catholic alike - propagated had resided in the culture since arround the mid to late 19th century, within various classes of society.

    For example the historic "Martin Luther" published his anti-semitic views and this was also used in the prosecution of the jews in the 20th century.

    the wealthy jew
    The wealth only some jewish entrepeneurs earned resulted in envy, indeed. It's one of those anti-semetic myths that jews in general are wealthy. But if one is to belong to a another group it is very easy to envy them, this is said to contrast the wealth gain of other entrepeneurs during similar times (Siemens, Krupp just to name a few)

    And this way the view on so called "sub-humans" jews merged with the old legend of the jews as being the killers of jesus and general evil-doers - aided by the envy.

    Jews were part of the society
    But the jewish people in the begining of those times were mostly far from being insular people, but the plan of the Nazis was to exclude the jews from the society ("Don't buy from jews", was painted by the "SA" - onto the window of jewish owned shops)

    Popular jews of the time for example "Albert Einstein" also a certain amount of actors. Jews mostly were assimilated into the population, and sometimes only learned of their heritage when by the "Ariernachweis" - documenting their heritage of having jews or no-jews up to the grandparents level in their ancestry.

    And btw. the Nazis sucked money everywhere - gold possession for example, (e.g. use of gold for wedding rings).

    Genocide
    The appearance of a genocide is not bound to people being poor and others being rich. Its based on hate and the possibility to express that hate freely and to incite action against others.

    Examples:
    "Huti / Tutsi" / 1990s
    "Turks / Armenians" 1915

    Explanation:
    SA - "Sturmabteilung" - a group of violent street thugs of the NSDAP - put into uniform and later made deputies of the police
    to uphold the "public safety". In contrast to the SS "Sturmstaffel" which was the militarized section of the NSDAP

    1.a) the root server is a remote server: yes

    iscsi just exports the local drives to the localhost
    then my homeserver tunnels into and the iscsi-"client" (I hate the iscsi nomenclature) connects to localhost.

    The tunnel is for authentification purpose(yeah iscsi can use some auth too but I was just lazy and wanted to have an small footprint config) and also for security because I do trust "ssh" much>much>much more than putting out an iscsi-server - even on a non-std. port number onto the internet. With the ssh-tunnel I kill two problems with one tool.

    Then 2x "geli" takes over, so my final encrypted iscsi device is "/dev/da0.eli.eli" (= yeah I'm paranoid)

    And rsync syncs only the files & directories that have changed, which is pretty efficient, also in terms of bandwidth usage.
    I get the full bandwidth out of my connection.

    Rsync works great also for local directory syncing.

    The encryption and decryption is 2x 100% done on the homeserver so my root server as well as my local backup server are just "dumb" providers of disk space.

    1.b) using cygwin and the ssh-client I can even export those drives directly to windows(works like a charm) - except that windows cannot work on ufs2 :)

    In the past I employed low power NAS-Servers so geli+ZFS was just to hefty for them to use and UFS2 does the trick for me,

    The scripts to balance this "hash tree" got pretty messy so I dropped that approach.

    Simple and short answer: Yes.

    I value my data, my privacy and the data integrity to be important enough to warrant that much effort .. and from my point of view, people that don't, will realize that later, what they lost, but only when it happens.

    I'm aware of the dangers of the offline and the online world and as such I take the neccessary precaution not to get worried over the awareness.

    Example, my house burns down I buy a cheap computer and restore my data from the root server.

    And that much effort .. you really think I do this barrage by hand ? .. in case of server reinstall:
    I have a custom FreeBSD-memstick image with precompiled specific config files. This setup however is only semi-automatic.
    So it takes about 5 minutes.

    the operation
    - home backup server is started by the homeserver via a Silvershield USB switchable socket (using my intrusion detection raspi as an intermediate) and the backup starts automatically.

    The ssh-tunnel to my root server is initiated via a pub/priv key.

    So I do not have much of an effort because most of it runs unattended, the sanity is checked by another script (-> database of hashes, if too many hashes do change .. I get a red light). And at times its fun to just lay back and watch the system do its job.

    The setup is also fun to extend and to automate, the Silvershield is the latest addition - Rome was just not built in one day.

  16. Full Disk Encryption & Backups & iscsi on Ask Slashdot: How Do You Prepare For The Theft Of Your PC? · · Score: 1

    Some questions to start with:
    1.) Why keeping a hidden encrypted partition?

    Its easier and more secure to have FDE in place because some programm .. perhaps notepad++ might buffer for example the text files that contain your passwords (password managers have some security issues themself).

    2.) Backups / local & online "offsite"

    Do you maintain the internet connection for your parents? .. put a small remote controlled server there and store only encrypted data on it.

    encrypt backups too :)

    here is how I do it:

    1.) local data is encrypted and on a homeserver that has FDE

    2.) my backup home server is just an iscsimachine the encryption/decryption is done on my homeserver and the disks are just "exported" over the network via iscsi

    3.) my root server is an iscsi machine too and is handled the same way as my backup home server over an ssh tunnel.

    The backup is done via rsync and I maintain a database of hashes for all files and locations (helps to reduce size by finding double data)

    4.) I do a desaster simulation once in a while .. because having a backup is one thing, being able to restore all data it is another.

    5.) When I'm not at home my computers are powered off, except an additional intrusion detection system. (old raspberry)

    6.) all my computer I take with me are stone aged - yet still 64-bit & ssd accelerated - netbooks - cost ~60-80 USD + the ssd(only 128 and 256 gb) = low cost

    Idea:
    It might be a good idea to have a "tripwire" partition in place that boots unencrypted unless you switch the boot manager to the real FDE partition on prompt. This tripwire installation can signal GPS position over a 3G-card or take pictures via the webcam and make other remote control stuff possible.

    To my knowledge all 3G cards provide also gps data over a virtual comport. (= no extra special hardware neccessary)

    Because its no such big deal to put much power into a car, the problem of aerodynamic lifting forces come into play interacting with shock absorbers.

    The space between the street and your cars under-floor at high speed can make out the difference between driving and flying,
    because more distance to the road = more air being pushed under the car = lifting your car off the ground.

    But Sweden could be obliged to grant asylum for Assange due to his situation.

    If would face death penalty, Sweden cannot extradite him right away -> European human rights charta.

    If you decide to implement server-level encryption across all your servers,

    This is basically simple you can build a server that does all encryption in ram, meaning the OS is loaded once then the encryption key is used to have it decrypt the content for the outside.

    To stop tempering you could setup such a server yourself and equip it with various sensors that detect presence of people or tempering, and if detected it could shut down not compromising the encryption key to forensics.

    Firewire(because of its DMA) needs to be disabled and unkown devices need to trigger a shut down event and must otherwise be ignored

    con:
    However this type of server would still emit the key data as radio spectrum.

    con2:
    The requesters question is quite sketchy, I suggest writting a specification first with the neccessary "must haves" and possible use cases.

    my iscsi-encryption approach
    So I can only explain my private approach, I got a root server with big harddrives and those harddrives are exported via iscsi that iscsi-connection is tunneled through ssh.

    I de-/encrypt & mount the drives only on my home server and sync the directories with rsync. The harddrives are double encrypted meaning I have two encryption devices and two dependend keys.

    This sounds slow, but it isn't I get nearly the full upload bandwith of my connection.

    Meaning my root server never "knows" what data is backed up on it - its a "dumb" server

    I would suggest a similar approach for the requesters situation, because it solves a first step, separating the encryption key from the encrypted data.

    And a second step having two encryption keys making it more difficult to get all two if separated (which is contrary to my use case)

    I would expand my approach there to have a "data" server, a level1 encryption server and a level2 encryption server.

    level1 decryptes the first encryption layer and level2 does it with the data provided by level1

    Usecase:
    If only the data server is seized, shut down at least one of the intermediate servers along with its key and the data is inaccessible. And it doesn't matter which "key keeper" server you kill, its a fail-one-fail-all system.

    The drawback is however the level2 encryption server shall not be compromised, because there all pure data is accessible.

    encrypted backup
    With todays highspeed connectivity the servers can be backed up by just cloning the harddrives over iscsi for example, that works quite well.

    another idea
    Most encryption providers from linux and bsd provide the possiblity of having more than one master key.

    Iscsi can also work on image files so you can provide many independed iscsi-volumes and encrpytion can be outsourced to the users computers.
