    Also note the last part of Theo’s reply to that mail: “ps. Disable Intel Hyper-Threading where not needed, until we all know more.”

    1. 7

      After Spectre/Meltdown were disclosed we made a similar decision. Not uniformly: we haven’t disabled it on every one of our physical hosts–we’ve done it where we could. Given the significant chance of further CPU vulnerabilities it seemed like a reasonable decision. Time will tell.

      Thanks! Having a place to sleep during a hackathon is very important to me and this makes it happen :)

      1. 14

        That, and the fact there is a hackathon to start with!

        1. 10

          What? Why are you wasting valuable hacking time sleeping? ;)

          1. 3

            At the very least, one could sleep on the keyboard, like real hackers. Then blame the cat for all the noise. There is a cat in the hackathon room, right?

          2. 1

            hehe

          1. 7

            While the tool seems like a handy one, it does sadden me that in this day and age the installation method is curl | sh.

            1. 4

              Agree 100%. I don’t know how that dire mechanism of installation became “a thing”. FFS, it’s everywhere and it annoys the hell out of me. I guess people can argue that it’s the same as make install as root (which I also dislike), but at least we’ve moved on in that realm, to binary package managers.

              1. 1

                What would you prefer?

                1. 4

                  A traditional tarball for a start? And for those that use it, the ability to install it using their package manager of choice (I see Homebrew support is on the way).

                  1. 3

                    A traditional tarball for a start?

                    Are you just saying you prefer to untar > ./configure > make > make install route? I don’t really understand the benefit of a “traditional tarball” other than if it had an MD5 to go with it to verify package contents.

                    And for those that use it, the ability to install it using their package manager of choice (I see Homebrew support is on the way).

                    Yeah, I definitely prefer a package manager to curl # | sh

                  2. 2

                    Most anything that’s not curl|sh really…for homebrew users there’s hope though.

                1. 11

                  Learning and reading about new technology and futurism. Reading science fiction and non-fiction. Hiking. Guitar and other music. Figuring how to increase my value as a human.

                  1. 2

                    Read any good sci-fi novels recently?

                    1. 8

                      Not the OP but wanted to mention Seveneves - I really enjoyed it.

                      1. 2

                        Added to my “to-read” pile.Thanks.

                        1. 2

                          Yes!!! I just finished this - I liked it a lot but not as much as Snow Crash, still a fantastic novel.

                          1. 2

                            I started this a week ago! Really enjoying it :)

                            1. 1

                              Ian M. Banks Consider Phlebas and even better The Player of Games. Both part of the Culture series. This is the ONLY science fiction future society that leaves me saying “Sign me up! I’m there!” :)

                            2. 4

                              The Metamorphosis of Prime Intellect
                              The Martian

                              1. 5

                                +1 for The Martian

                                1. 2

                                  +1 for The Metamorphosis of Prime Intellect

                                2. 3

                                  Diaspora by Greg Egan always tops my list.

                                  1. 1

                                    Just finished Cat’s Cradle (not obscure but a classic), and now starting on the Foundation trilogy (finally). As stated below, Neil Stephenson’s Seveneves was a veritable page-turner. Also anything by William Gibson.

                                    1. 3

                                      Reading up on Stanislaw Lem. Foundation was awesome, but Lem… Summa Technologiae should be taught in schools!

                                      1. 1

                                        I tried reading Lem’s Futurological Congress book, but it was just too silly. On the other hand, the Cyberiad somehow hits a sweet spot, it’s one of my favorite books - I made my dad read it to me a lot of times when I was little, and I still really enjoy it.

                                1. 1

                                  @jcs I think it would be cool to have a “Devio.us Admin” hat for myself, @bcallah, and @kyle.

                                  Also, @bcallah totally needs an OpenBSD Developer hat (even if he won’t ask for it himself)

                                  1. 1

                                    I can has too?

                                    1. 1

                                      (To clarify, jasper@ is an OpenBSD dev, not a “Devio.us Admin” in case that wasn’t clear.)

                                      1. 1

                                        You has.

                                      2. 1

                                        Oh I totally forgot @lteo is also an OpenBSD Developer.

                                        1. 1

                                              Huh I totally didn’t see that before. (And I didn’t see you request one.) Oops.

                                        1. 6

                                          Shameless plug, but M:Tier has released binpatches already:

                                          1. 2

                                            Perhaps a bit late to the party, but Wallabag is quite nice too. While there’s a hosted version available, you can host it yourself too for those who rather keep control of their data. They also offer extensions for Chrome/Firefox and apps for Android, iOS and Windows Phone.

                                            1. 1

                                              Hmm. I need to check out efifb. VESA hasn’t been bad, but the grass is always greener…

                                              1. 2

                                                You’d run either VESA or WSFB on top of efifb(4). Not either instead of efifb(4).

                                                1. 1

                                                  efifb with wsfb, I mean. Is the console high res with efifb? Not that I spend much time on console, but the VGA stretching is pretty ugly…

                                                  1. 1

                                                    It’s alright. I haven’t counted the cols/rows, but judging by efifb.c:EFIFB_{WIDTH,HEIGHT} it’s 100x31 with a small-ish black edge around it.

                                              1. 1

                                                Hmm, does this 404 for anyone else?

                                                  1. 3

                                                    Looks like @jasper’s site has a wrong canonical header, which the URL submission page switches to when it finds one:

                                                       <link rel="canonical" href="http://jasper.la/openbsd-uefi-bootloader-howto/" />
                                                    
                                                    1. 1

                                                      Thank you for pointing that out; it’s fixed now.

                                                        Clicking the post’s URL http://blog… returns a 301 to https://ghost.jasper.la/openbsd-uefi-bootloader-howto/ which doesn’t resolve. If I visit https://blog… it works.

                                                1. 1

                                                  @tedu: Is this like most ARM boards where u-boot and all the configuration is stored on the flash’s fat partition rather than firmware? If so, given the lack of removable media, any idea what the recovery path would be if one were to dd /dev/zero over sd0c? I’m assuming it wouldn’t be completely bricked.

                                                  1. 3

                                                    As far as I know, all the u-boot stuff lives in ROM (or NVRAM). The FAT partition houses the kernel, but I think you can netboot it if bricked. Maybe…?

                                                    1. 3

                                                      Depends on what you mean by “bricked”. I’ve bricked an ERL two years ago but that was damage from (un)plugging the power cable too often (before I finally able to let OpenBSD reboot the machine). That had little to do with software-wise bricking and I haven’t been able to brick the replacement unit in a long time with all kinds of uboot abuse…

                                                    2. 1

                                                      To answer my own question, a little research indicates that the internal flash is a removable USB drive, and should fit most low-profile USB flash drives for repair or upgrade.

                                                      1. 1

                                                        There is only one internal port […]. The internal flash is not supported and it’s not all that much anyway.

                                                        There’s an MSDOS partition on the USB disk, maybe it’s the one the kernel is loaded from :
