  1. Are there any drone pilots on SFN? I just got me a Mavic Air 2, I’m charging the batteries and I’m off to my first flight...hopefuly not last 😄

      Mitnick v2.0 would use the drone to see what the user's password is through the window..

      ps. Measure maximum mass of cargo that it can hold. You could use it to e.g. send your wife forgotten to work sandwich or so..

  2. Can anyone identify if these factors are close?

    i realize that the numbers are huge. I am facing the same problems as you trying to see if this works.

    The goal is not to destroy RSA and those ciphers that rely on factoring. That would cripple SSL certificates. We probably don’t have any encryption the NSA can’t break.

    Instead finding patterns in factorization finds new patterns and series.

    I would like to find patterns in biological organisms, but I no little of genetics or cell biology.

    There are mathematicians and physicists looking for patterns in diseases. I am neither of theses, but finding pattern is the most basic math. If if you don’t understand the theories or notation you can still visualize the series. I am not saying it is easy to add to the field, put anyone can understand patterns.

    That is how I feel. Let’s find patterns in factoring.

      You should not send something confidential through HTTPS/SSL. Properly (professionally) made websites hash passwords on client-side in JavaScript HTML Form validation code.. So even if SSL is compromised (e.g. SSL Strip) password is still encoded.

       

      Somebody bothering about security should archive the all data using 7zip with password. It is using AES 256. But it is not allowing to enter IV by user..

      We probably don’t have any encryption the NSA can’t break.

      AES has been approved by NSA for encryption of non-classified data, later extended also to classified data. With enough power e.g. supercomputer cluster or botnet with gpu acceleration, or better custom made hardware cluster for 10 bln usd, if there is known IV (init vector), or simply leaved zero by incompetent programmer, not knowing what he or she is doing, or using wrong mode, it is possible to find out password (especially 128 bits long) in some reasonable amount of time. Therefor to decrease of chance of brute-force attack on transmissed data the key is to frequently change IV (randomize?) and transmit it together inside of already encoded packets (or alternative route). If somebody (gov) will intercept transmission in the middle, won't be able so easily use plain brute-force algorithm if IV can be anything having 128, 192 or 256 bits and changing. Ordinary hackers don't have ATM patience nor resources to brute-force pass through the all possible passwords even if they know IV.

       

      Example of what can happen if raw picture is encoded using silly insecure mode is on this website on the right.

      @StringJunky Nice feature to have these days is ability to receive data through WiFi and Bluetooth, and print directly from SD/SDHC. Worth taking it into consideration during ordering of new printer. They will allow printing directly from digital camera, smartphone or tablet, without having to transfer files back and forth to the computer.

      When I wanted to do massive printing I bought the cheapest from the cheapest inkjet printer (Canon Pixma MG2555) for 30 usd (in Christmas holidays promotion). Brand new replacement cartridge for it costed more than half of printer price, IIRC around 20 usd (with built-in heads). I printed the first bunch of pages with original ink, lasted just for couple hundred pages. Then bought refilling kit with syringe for around 5 usd. And managed to print more than 10,000 pages with it (> 5k double sides). I counted that if I would be buying original cartridges or non-original cartridges I would spend more than 1000 usd on ink. I paid total 35 usd for printer and ink. Price of paper and transparent foils for each page costed 175 usd. The most annoying thing was need to swap page to fill 2nd side. It took couple weeks (entire day work) to print the all stuff.

  5. Its been a week here, skin is peeling of my shoulders and I’m officialy an african with blue eyes. I also have indigestion from all the great food theyre serving to which I cant say no...and my feet are burnt. One more week of this „nightmare” and I can finally go back to normality. I’m half way through Frank Herbert’s „Dune” which I never read who knows why. Oh and I hate „Ouzo” with its aniseed taste @MigL

      (without surprise) I understand that you are more interested in enjoying holidays than book talking. Yet you mentioned it, so I jumped in with my (rather not valuable) "input". Perhaps you will see what I meant if/when you get to IV. "God Emperor of Dune", V. "Heretics of Dune" and VI. "Chapterhouse: Dune"..

      "Dune" is entire series.. 6 very thick books... the higher index, the harder to get through them.. The first two are relatively easy.

  7. Just a warning - testing using a new PSU how not yet tested LED emitters do amperage wise on a Friday evening while drinking whiskey does not render viable results and renders precious LED’s dead. Learning is expensive.

      Chinese workers are grateful and ask for more.... ;)

       

      LED strips typically have built-in resistors on the tape. But they require correct polarization.

      It's wiser to use too high value resistor, at the beginning, and have too little current, then decrease its value.

  8. The Notre-Dame cathedral is burning down right this minute. It is sad to watch an 850 year old monument go up in smoke. Apparently the big wooden steeple which was 70 meters high was constructed with lots of lead elements so as soon as the structure caught minor heat it all went like domino. I’ve been to Paris twice and never had a chance to see the cathedral, stupid me.

      Better translation will be:

      Obviously these words were just slogans for not bright people..

      Communists are using direct invigilation and direct repressions against opposition, partners and friends, whom they want to eliminate.

      Capitalists are using hidden invigilation ("Internet laws", "anti-terrorists laws" etc.) and indirect economical repressions against people who don't want to participate in their eternal rat-race (which is giving them profits and power)..

      There is Miller-Urey experiment

      https://en.wikipedia.org/wiki/Miller–Urey_experiment

      Did you hear about it?

      If you will heat, pass current (spark in experiment, in the real world thunderbolt, lightning), cool down, then repeat, mixture of gases such as CH4, CO2, H2O, NH3, HCN, H2, N2, O2.. after a while there will be created the all kinds of organic molecules, amino acids, proteins, DNA. e.g. you can make C5H5N5 (adenine) from 5 HCN.

      I have seen it multiple times. Disk not possible to be formatted for Windows, and make bootable, but can be 2nd disk. Have collection of them.. ;)

       

      Sometimes, in old times ('90 years) partitioning on AmigaOS, and formatting on AmigaOS, could help..

      After that, and moving disk back to PC, it could still be used.

      (old times, original Amiga can't have SATA disks)

Its a known and defined problem apparently but nothing worked including reinstalling network drivers from USB (yes I flushed DNS and did all the CMD procedures) I had to rollback to previous OS version. I don't even know which update did it, I don't have time to look now. Beware of the latest Win10 updates!

      You should try going to website by IP, entering f.e.

      http://127.0.0.1 (install XAMPP if you don't have Apache installed locally *) or f.e. http://151.101.113.67

      (CNN IP Address)

      This way you will verify whether it's DNS issue, or TCP/IP packets are blocked (firewall?),

      whether it's Internet related problem or it's even local HTTP server not working..
