If you're OK with how I shared stuff up till now, you will not need to do anything. If you want to limit seeing some stuff I post, I made a couple collections for the main topics I post about:

Role-Playing Gameshttps://plus.google.com/collection/Id4WX

Photoshttps://plus.google.com/collection/Qa2WX

Technology: https://plus.google.com/collection/8PVXX

IT Sechttps://plus.google.com/collection/oahM9

signalboosthttps://plus.google.com/collection/UZojX

I'll try to adhere to post to these topics; but there is  other stuff I've not collectionized yet, like personal bloggy things, for which
there may be future collections too if this works out; i.e. I am considering splitting German and English, but haven't done for now.

If you want to read more about collections, check out this link: https://support.google.com/plus/answer/6210271

If you have more questions, ask them as a comment to this post. I will try to answer them, and will regularily clean up questions and answers without longterm value.

I'm considering making collections for all my posts, so that folks can manage their interaction with me.

Reversing go binaries 
GO binaries are weird, or at least, that is where this all started out. While delving into some Linux malware named Rex, I came to the realization that I might need to understand more than I wanted to

Time to stock up on strategic popcorn reserves. Looking forward to more great bug reports out of ProjectZero when Halvar joins.

+Stefan Funke​ built a sample tor relay setup to use with the SysEleven Stack. Pretty painless it seems (-:
 
Sep 23 14:09:22.000 [notice] Heartbeat: Tor's uptime is 30 days 23:59 hours, with 3168 circuits open. I've sent 2147.58 GB and received 2105.04 GB.

Vor einem Monat habe ich beschrieben wie man dank IaaS und Terraform einen Tor Node startet. Einen Monat später hat der Demo-Node dank #SysEleven 4TB Traffic gemacht und das Tor Netzwerk verstärkt.

Jetzt gibts ein Kernel Upgrade und dann kann der nächste Monat kommen.

I, too, like to watch the world burn.

Let's be good Tor citizens though and make sure to follow recommendations on spinning up a bunch of relays in the same location with the same operators at the same time. Don't want it to look like some sort of attack.

August and Hunter are former colleagues of mine and will tell you about BeyondCorp. If you are in Amsterdam for this conference, I wholeheartedly recommend attending this talk.

As already mentioned, Brian Krebs is back online

I want to point out something mentioned here:

https://yro.slashdot.org/story/16/09/25/1638241/krebs-is-back-online-thanks-to-googles-project-shield

I think this important:

... but says the situation is exacerbated by the failure of many ISPs to implement the BCP38 security standard to filter spoofed traffic, "allowing systems on their networks to be leveraged in large-scale DDoS attacks... the biggest offenders will continue to fly under the radar of public attention unless and until more pressure is applied by hardware and software makers, as well as ISPs that are doing the right thing... What appears to be missing is any sense of urgency to address the DDoS threat on a coordinated, global scale."

I'll attach a link to BCP 38 below... Thanks to every ISP implementing it already.

#beyondkaputt

Anyone to claim that the inevitable loss of "backdoors access" / "golden keys" would be treated more responsibly?
 
Get this: NSA knew someone had stolen their 0-day exploits for three years. Someone surely decided that losing access (i.e. the exploits) would be worse than the fact that somebody else could also gain access. Who cares about the security of the potential targets? Yeah, right.

Squirrel!
 
"For this, participants were shown a list of activities (e.g., biking, reading) directly below the following instructions: “Below is a list of leisure activities. If you are reading this, please choose the “other” box below and type in ‘I read the instructions’”. This attention check proved rather difficult with 35.4% of the sample failing (N = 99)."
Although bullshit is common in everyday life and has attracted attention from philosophers, its reception (critical or ingenuous) has not, to our knowledge, been subject to empirical investigation. Here we focus on pseudo-profound bullshit, which consists of seemingly impressive assertions that ...

I'm all for this nonsense. It's an object lesson in not blindly believing everything you read on the internet.

My friend's dream is to be in musical theater, on stage, in Broadway.
But her experience in being in productions is limited to Israel and unpaid parts.
Any of you, friends, can put me (and by that, I mean my friend) in touch with someone deeper in the business for some Q&A? She's not quite sure what to ask, nor of her precise path to her dream, but part of the Q&A is to figure that out.

Any help is appreciated, be it a contact or a signal boost.
Thank you.

Story
Tagline
For every terrible idea, there is an equal and opposite terrible idea.
Introduction
My friends are online. My home is the internet.

There is no 'from.'
Not in the sense that one is immersed in, influenced by a single defining culture anymore, save maybe that of the 'net.
We are jet-setters, internetters;
we've all moved for work and for love, time and again.

My culture is cosmopolitan.
My friends are online.
My home is the internet.


My collections:
  • Role Playing Games for pen-and-paper RPGs
  • Photos for photography
  • Technology for assorted IT and other technology post
  • signalboost for random reshares of stuff from the internet, esp. if it doesn't fit any of the other categories

Drei Minuten vom Trubel des Bergmannkiezes entfernt ist das TreXanh ein kleines, aber feines vietnamesisches Restaurant. Die Karte ist genau nicht zu lang, das Essen sehr frisch und lecker, und die Preise äußerst moderat.

Tolle Strände, durch das Autoverbot sehr ruhig. Romantische Abende auf der Deichkrone werden durch Mücken etwas getrübt.
