  1. Re:It's the media on YouTube Video Warned About School Shooting · · Score: 1

    I hope people are more sane in Finland than over here in the states

    I hope so. At least teacher's union stated that they do not want metal detectors and guards to schools but rather allocate resources for pre-emptive care. In schools it is very important to access any problems with learing or in mental health early; it is good for those individuals and also economically sound for society.

  2. Re:2 SUNs == remote control on What Bizarre IT Setups Have You Seen? · · Score: 2, Interesting

    For a temporary installation we had bunch of PC computers installed on a remote location. Those were controlled normally over ethernet connection, but I decided to run serial cables between them in case something odd happens with management port, like running ifdown for a wrong interface. It was a cheap insurance, and if I recall right, it did save one 1500 km trip.

    About wrong installations, I remember that when one designed thin ethernet cabeling, they did not remember to take into account cables between wall socket and computers: it easily add 10 meters for each desk PC. Thus if you originally were in limits (185 meters), after some years your network segment was 350 meters and had strange network problems on some hosts.

    Is it any wonder those with lower income would opt for the McDonalds food?

    Not only McDonalds, but in general you get cheapest energy from fat. Thus, if you are with low with budget, you are high with fat. There are other reasons too, like not caring about your health, not knowing about healthy food , etc. in lower social classes. The correlation is just the one what grandparent says, not the one indicated with the original text.

  4. Re:DGPS sites on internet on Is National Differential GPS Lost? · · Score: 1

    In theory yes, but you won't get the needed information from a normal GPS receiver. To calculate DGPS correction, you must calculate error for each satellite and feed that to other GPS receiver. If you just take difference between the right location and the location you got from NMEA output and use that to correct postition indicated by other, you will get greater error than without.

    This is because each receiver picks a different set of satellites.

  6. Re:the low hanging fruits on ISPs to Create Database to Combat Child Porn · · Score: 1

    There are plenty of those. Recently one well-known data security expert was arrested for both abusing child and also having child porn on his computer. For me that was the most surprising aspect of whole thing: how a well-respected security expert would leave that kind of material unsecured.

    It is probably that rational thinking fails after certain point and one does not count to be catch.

    Finland is implementing similar DNS-based blocking for child porn as Sweden has. One expert from police complained that it makes them more difficult for them to pick that low hanging fruits before they actually abuse some child.

  7. Recommed PSU rating on Supermicro Announces Quad-Opteron 1U Motherboard · · Score: 2, Interesting

    Supermicro states quite high PSU requirements. I have few 1U systems that have only 250 W systems even if the motherboard spec says minimum 350 W. However, no stablity problems even with add-on cards.

    I guess they only want to play safe and do not want anyone to complain about instability because of too weak PSU.

    Orange book (and also later assurence evaluations) have very much focus on process to develop software, not for actual outcome. This is not so easy to do on OSS.

    This is very similar to ISO 9000 certification: you can be ISO 9000 certified and still your products can be total crap. You just has to document how you produce this crap. I daily eat on cafeteria that is ISO 9000 certified. The food is probably safe, but if I want to enjoy my meal, I visit some other place.

  9. It is not easy to buy redundant connections on The Backhoe, The Internet's Natural Enemy · · Score: 1

    It can be very hard to make sure that your connections are unaffeced by a fibre cut. I know a case where a company got redundant connections from two carriers. The connections leaved to different directions from both office buildings and everything seem to be fine. However, on one day both connections went dark at the same time. It turned out that the other carrier had leased one leg of dark fibre from the other carrier. Thus both connections were in the same physical cable that was cut.

    It is difficult to get definite answers about actual physical routes and thus it is about impossible to know now close two connections are each other.

    You see, they say that their products are entirely spyware-free. Wait... does that mean that their products do not have any other spyware and their product does not have any spyware attached -- the whole program is just spyware, nothing else..

  12. Why RAID5, just replicate data on Cross Platform, Low Powered Home Servers w/ RAID? · · Score: 1

    Ok, RAID5 is c00l, but I rather work simple. For important data, I store it to two different disks (on different computers) and offline. For really important data, fourth, fifth location is that far away to protect from about else that direct hit by a large asteroid.

    I have EPIA PD10000 motherboard on my server (Debian, of course). Currently, there are 3 PATA disks (one old 60G from desktop and two quite new 250G) thus I have internal capacity to add more disks on PATA channel. Disks are configured to spin down after a period of inactivity. The PCI slot is reserved by DVB card, so I cannot add more [SP]ATA disk.

    However, there are many USB2.0 connectors and I'm thinking adding arhcive disks with USB. Those disks would be powered on-demand (using array of relays controlled by parallel port), thus in theory I could have tens of disks. USB2 transfer speed is sufficient for that kind of usage.

    I found an inexpensive USB to ATA adapter, but it is unclear how it works if the disk is powered down. Does anyone have experience on that?

    Of course, you must organise your data so that you will know which parts must be replicated and what data you allow to lose.

  13. Re:microwaves more than 100% efficient? on Company Develops Microwave-powered Water Heater · · Score: 1

    Well, I have distributed heating (where water is heated in central location, many cases as byproduct when producing electricity) in my house. When I have two showers on, the heat exchanger (transfering heat from circulation water to tap water) takes about 120 kW of power to heat water. My incoming 3-phase 230 V, 25 A line can provide only one quarter of that power.

    In reality, electrical heating coils are not that massive. The reason to have a large tank of heated water is to handle somebody visiting shower.

  15. Of course it *CAN* be invasive on Cell Phones to Monitor Traffic Flow · · Score: 1

    Your cell phone provider is collecting that data anyway -- maybe not storing it for extended period of time -- but the data is collected. You can do this kind of tracking in a two ways: the right and the wrong.

    To do it right way, you use temporary identifiers (GSM network uses them anyway) that are anonymious and drop all routes that have too few mobile phones; like if you are living in a rural area and are the only one that takes specific route. After you have made analysis, you drop also temporary identifiers. This does not introduce any more privacy problems than normal operation of cell phone network.

    You can get all the information you want to estimate traffic jams with this method.

    Of course, you may want to do it wrong way and collect also phone numbers, called numbers and even record calls that are made. Very usefull, if driwing when talking is prohibited in your area. That is something a national security will need :-). Thus EFF should be worried about this.

  16. Re:No redundancy? WTF? on PetaBox: Big Storage in Small Boxes · · Score: 2, Interesting

    The archive.org maintains its archives in several geographicaly different locations and files are mirrored between those sites. If one disk or node breaks, you still have two or more copies of that material.

    If you archive serious amounts of data, redundancy within node is not the best solution, but to distrbute information between systems. For very important data, you can have as many copies as you have nodes; lesser important data may have just a single copy. If it gets lost, then ok, shit happens but so what. For example, I have just a single copy (no backups, partly RAID) of 10 TiB data (and that data is not available from P2P shop) because it is not economicaly viable to make backups. On the other hand, I have some data in 5 geographicaly diverse copies, both on-line and off-line.

  17. Re:wouldn't it be cool on Nokia and Intel Group Up To Develop WiMax · · Score: 1

    Sure, it would be nice to have ad hoc networking, but there are several problems; most visible to user are:

    • battery life, as you wireless device must also relay other people traffic
    • latency, as each wireless hop contributes a delay (WiMAX is better than WiFi, but still)
    • network stability, as radio environment changes (MIMO may help for that)
    • security issues, both for user and provider,

    Anyway, I saw recently one slide from Nokia that they estimated that after 4G (that starts around 2010) there won't be a network anymore 2020 as we know it now...

    Like water, or electricity that is provided by local utility company. Even if I get better water from tap than from bottle, it does not stop bottled-water companies from selling their products with good margin.

    There are always a market for better service: that is something private companies can provide. But for bulk broadband access, it is most efficiently done in centralised manner - no need to dig cables for each provider for every house.

    Let the community take care of raw, low-margin access, top it with your fine private premium $ervice$. Technology will develop even further, so one should not commit for old technology but use each time the one providing best price/performance ratio.

    My back has single use 4-digit code that are sent in bactches of 80 codes. You use your user id (that was not sent you by mail, you got it personaly from bank) and that single-use number to log in system. That was in 1980s when you used modem to connect online bank. When internet banking started, they add another security measure, 4-digit confirmation number that is a random one out of 26 (a-z) that system asks when you have done some transactions. The confirmation numbers change also when you get new set of sign-on numbers.

    If the phihser manages to get the single-use number, he shoud do active man-in-middle to get the right confirmation number.

    There is also a closed messaging system, that you can use to communicate with your bank representative.
