    I had occasion to see cheap Ebay li-ion batteries "explode". There is a pop, but that pop is then followed by a small tongue of flame and smoke. This lasts a few seconds but it ruins whatever that tongue of flame was pointing at. I certainly would not want that in my pocket.

    I'll chime in for the "actual experience" bit. I've twice seen li-ion batteries suffer catastrophic failure due to mishandling. Both times it was cheap Ebay Nokia replacement batteries that went up in smoke and a bit of flame after the phone was dropped.

    Exactly. The bank needs to know that I'm visiting. Nobody else does.

    HTTPS ensures that I can trust that what I see came from the bank. Tor ensures that nobody other than the bank knows that I was there.

    I came looking for this. I have a few good reasons for visiting my bank via Tor, and the truth is that I would leave the bank if Tor were blocked.

    Blocking Tor is akin to saying "many robberies were performed by blacks, so we will no longer allow blacks into the bank".

    I think that you are right. A system moving close to C will be as stable as a system stationary relative to the distant background. However, the interaction which causes such a system to accelerate to C would destroy most fragile structures, likely including most planetary orbits.

    You should have seen the Talk page. The page was closed as it was deemed "clearly promotional". Here is the text of the page that I managed to get up in about 10-15 commits before it was deleted:

    Devuan is a fork of the Debian Linux distribution created as a response to the inclusion of systemd in Debian[1], and thus will include SysV Init as the default[2][3]. Thus Devuan will join Slackware and Gentoo as a mainstream Linux distro without Systemd[4]. More gerneally, Devuan ensures that "Debian packages won't become dependent on any single init system"[5]. Devuan is intended to "protect the freedom of its community of users and developers"[6]. Devuan is prononuced as "DevOne"[7]. The initial Devuan release is expected to be ready by the time that the next Debian release is ready, in order to provide a seamless upgrade path [8].

  12. Re:High Resolution Stills via video on Ask Slashdot: Best Drone For $100-$150? · · Score: 1

    If you pick up something with reasonable video resolution that can do I-Frame only then you can use multiple images to do a super-resolution still. The premise is easy... Multiple images will not cover the exact same pixel positions (unless the drone is affixed to a stationary point). You can use this fact to merge multiple images into a single one with much higher resolution than any of the single images. The more images that you can overlay, the higher the resolution you can squeeze out.

    The trick is to have good alignment and warping algorithms to do the overlays. I've done this for an employer in my previous life with impressive results.

    I belive that there is software used for astronomy photography available which performs this function, but I've not found anything satisfactory. Is there any software that you could recommend, seeing as you seem to have written some yourself? Thanks!

    Where is "east" on the comet?

    The comet's axis which appears to spin in a counterclockwise direction from above is its north pole. From a location in which the pole is perpendicular to the angle of view, east is the direction against the comet's rotation, i.e. the direction which appears to be rotating towards you.

    Admittedly, this is somewhat difficult to imagine for a non-spherical object, but it works out.

    Thanks. Going through this thread I do see that the consensus is against the use of port 465. I find this strange, but not the strangest thing that I've seen this week. Thank you.

  19. Re:Anti-Spam Measure? on ISPs Removing Their Customers' Email Encryption · · Score: 1

    MTA to MTA is still on port 25, yes, but mail submission via a MUA is no longer recommended on port 25, and many ISPs specifically block 25 as an anti-spam measure.

    MUA submission is done on:
    1) Port 587 plaintext, or
    2) Port 587 encrypted by specifying STARTTLS, or
    3) Port 465 encrypted

    I've not heard that 465 is depreciated until now, and in fact I actively avoid STARTTLS so I use it.

    I am aware of port 25 being depreciated, but not 465. Is there an RFC that I should be reading? I still submit mail specifically on port 465 so that I can avoid STARTTLS and require encryption. Of course, seeing how I manage the MTA I have that luxury.

    If port 465 is no longer recommended I would like to know when and why that happened. Thanks.

  21. Re:Always RTFA on ISPs Removing Their Customers' Email Encryption · · Score: 1

    If you're relying on the MTA to keep your email communications secure, you're doing it wrong. If data is important enough to encrypt, encrypt it at the sender side first.

    In this case, sending email over TLS is akin to browsing the web over TLS: You let the browser / MTA handle the encryption at a lower OSI layer than the application layer. Thus, it works transparently and without hassle to the end user. Would you suggest using GPG to manually encrypt and decrypt all your communication with any HTTPS website?

    Note that the STARTTLS command is a fix for using port 587 to send encrypting mail instead of the port which is dedicated to it: port 465. It is like sending HTTPS down port 80 with a special flag. Properly configured MTAs should be using port 465 for email over TLS instead of port 587 with a "special flag".
