The Awkward Silence

I think I was nice, the problem was that I started asking things the teacher didn't know anything about. In univeristy it is a lot more appreciated to argue yea :)

I actually was really shy and found someone who was as nerdy as me, after this we were the loudest and asked the most questions and drove some teachers crazy

Tinkeringbell

@Peter Oh, ignorant teachers XD Mom always explained to me (especially primary school) that I was there to learn how to deal with people, not to become smarter XD

@Peter Oh boy, a golden duo XD Those are sooo annoying in class XD

Peter

hmm, I just wanted to hoard knowledge :D I can imagine this was quite frustrating for other people yea, since we always read before a lecture started, so we already knew everything before he started explaining things. :)

Tinkeringbell

@Peter Which in a way is nice ;)

Makes the lessons a lot easier to follow, and to sound intelligent asking questions AFTER

:P

Peter

yep :D I still have that drive to hoard for knowledge, it really motivates to learn more :)

however I think I'm more balanced with asking questions now, something I learned through the years I guess

Tinkeringbell

@Peter Yeah, you'll pick up on that eventually ;)

I did too.

Peter

8:11 PM

yep :) It took a while though hahaha, it was a fun time :)

atleast for me it was fun, can't speak about the other people in class

Tinkeringbell

What time isn't? I had fun today too...

(am still having some right now ;) )

Peter

I'm also having fun right now :D

I reflected a lot about myself today, which hammered learning a bit but was a nice day :)

Tinkeringbell

Ah, self-reflection. I look in the mirror every morning for about 3 minutes while doing my make-up, and I leave it at that ;)

I spent most of the day calling managers and thinking about what I want from my career.

I got the call today that the project I'm currently on is getting some budget cuts, so I have to find a new customer/project to work on (I keep my employer though, it's not like I lost my job).

Peter

I have a mirror, don't really use it for anything actually. It looks nice on that wall :)

Tinkeringbell

I don't mind, because tomorrow I have a meeting with my manager and I was planning on discussing with him the fact that I feel a bit tempered in my progress/ development on the current project, now that doesn't have to be as awkward XD

Peter

8:18 PM

I see, thats a good time to discuss what to do and right in time because of the budget cuts

When I'm going to work I think talking about earning money will be quite awkward, since I don't really think about that now

Tinkeringbell

@Peter Yeah, I hope I can switch to something cybersecurity related. I've been interested in that for a while now, but other than programming best practices there wasn't much room to develop that interest on the current project

@Peter Hmmm.. I think you're used to it soon enough ;)

JAD

@Tinkeringbell hmm, I did an interesting internship at TNO at the department of Cybersecurity and Robustness

it's such a fascinating topic

Tinkeringbell

@JAD Sounds cool, what did you do?

JAD

tried to develop a statistical method for detecting periodicity in network traffic

idea being that an infected network will periodically check with some master server for instructions

Peter

@Tinkeringbell Would be nice if you could get that, good luck with the appointment tommorow :) Yea, I'll probably get used to it sometime, quite hard to imagine that now though :)

Tinkeringbell

8:22 PM

@JAD Well, I heard our company is a little short on the ethical hacker/ pen testing side, but also on the risk assessment and crisis management ... so, we do a lot of fun stuff and they train people internally, so I'm going to see if the manager is willing to put me on that.

JAD

so if you can detect a connection between two IP-adresses+ports that sends packets very periodically, it might be worth checking out

Tinkeringbell

Oh cool... that's mainly data logging and analysis then?

I think that's something our company does in combinations with third parties as well :)

JAD

no logging, we were working with already logged data. Just the analysis

Tinkeringbell

@JAD Oh, that's the best part anyway XD

JAD

so basically, per connection you get an array of timestamps, showing when a packet was sent

return whether it is periodic (enough)

so now what if I add randomness to the interval

Tinkeringbell

8:24 PM

Sounds deceivingly easy :)

(before you added the randomness)

JAD

so instead of every minute, check every rand.next(30, 90) seconds

Peter

I think it can be quite complex because of the time it takes to send packages right?

If a package is delayed, it could still be periodically send

JAD

@Peter yep, there will always be some randomness

although the times we used were truncated at 1 second

so it wasn't that big of an issue

but now what if I have a signal every 60 seconds

and I randomly inject extra signals

so instead of varying those 60 seconds, I add additional noise

Peter

I see :) however 30,90 is a big difference, is that a realistic scenario? I'm more in embedded programming, don't know much about networks

JAD

tricky. I don't think it particularly matters. I don't know enough about it tbh, but I'd assume that you don't have to check for instructions like ddos this server every minute exactly on time

Peter

8:29 PM

ooh wait the 30,90 are extra signals, I thought you would add this to the periodic signals, which would make it really though

or I'm half asleep at this moment haha

JAD

no, I meant that instead of sending every 60 seconds, you randomly send between 30 and 90 seconds later

which I admit is probably broader than we could still detect as periodic

Peter

I see, thats what I originally thought but got confused by the injecting extra signals part

JAD

yeah, two different ways of adding noise

you can very your periodic signal, or you can add additional signals

an earlier method took the time between signals, and tested for the standard deviation of that

which works nicely for 60 58 62 60 60 61 etc

Peter

seems logical :)

JAD

but if you start injecting extra signals: 60 60 20 40 60 60

it all falls apart

but I'm starting to approach NDA territory here, so I'm going to leave it at that

Peter

8:33 PM

hmm, this happens when a node sends information to multiple addresses right, Ok I'll stop asking more questions haha

JAD

nah, this was per hostIP + port + receiverIP + port comination

idea being that a botnet is connected to a single server

Peter

I see :)

Tinkeringbell

Ugh.... the suspsension is killing me! I need two more upvotes today to rep-cap (would need only 1 if there wouldn't have been 2 downvotes in rapid succesion on my cashier answer today :( )

Peter

I discovered today that there is a limit on how much reputation you can earn in 1 day

Tinkeringbell

@Peter Yep, I'm 14 points away from that :P

Peter

8:36 PM

he mind reader, I was first :)?

Tinkeringbell

Not! :P

Peter

it was close though, what time is the server? (eg when is a new day?)

Tinkeringbell

I think it starts at midnight for me... Don't know actually, I think it's midnight for everyone ;)

So there's still 2,5 hours left XD

Peter

oh cool, adjusting to timezone of the user is also a possibility, didn't thought about that :)

Rainbacon

I don't think it's adjusted per user. I usually see a reset somewhere in mid afternoon. I would guess that it uses UTC+00:00

Peter

8:43 PM

oh then you have still 3.25 hours!

Q: What is an SE "day"? When does each day start?

When does a day start on the Stack Exchange network? Some badges (Enthusiast, Fanatic, Mortarboard) and voting limits are bound by and relate heavily to the concept of a day. Do days correspond to calendar days? What time zone is used? Related Are there any voting limits? Return to F...

@Rainbacon was right ;)

Peter

digit comes weird though when you talk in hours, it becomes confusing

Em C

although it doesn't show you current UTC time anymore afaict

Rainbacon

@EmC I was just about to post that link as well

Em C

jk it does, I was looking under the wrong icon

Peter

8:45 PM

they changed the icon, I could edit the wiki hmmm

oh wait I can't I only have rep on this SE

Tinkeringbell

Well, I'm down to needing only 4 more points. Guess I'll reach a five day streak then

Peter

4 points is manage-able I think :)

Peter

9:04 PM

I'm going off, was a nice day and have a nice day all :)

Q: Mistakes with Contest Placings and Prizes

I just recently won a laptop at a game night hosted by my university. I came in second place at the event. Afterwards, someone realized there had been a scoring mistake and I was third. Now, the actual second place wants me to trade prizes with them, as they would prefer the laptop over the Am...

If the event wants to correct it then they can buy him a laptop. If they caught it before you got to your car then you should have returned it. — Paparazzi 40 secs ago

Q: Father wants me to give him my work number and I don't want to

I'm moving to a new town where I don't know anyone for work. My father wants me to give him the number and e-mail for my primary work boss because sometimes I don't respond quickly and he worries and he would like a back up contact. My problem is that I don't feel comfortable doing that at all....

As usual, Robot Hugs has some good stuff to say about gender identity.

user15026

(Also, now I want ice cream.)

HDE 226868

@Ash Mmm, ice cream.

user15026

I didn't get any when I shopped this week and I've been regretting that all week and this comic, while also being a good sort of intro to the idea of non-binary gender, also made me sad again that I didn't get ice cream.

HDE 226868

@Ash The best metaphors are both clear and tasty. That's great.

user15026

I thought it was a good way to introduce people to the ideas, and thought maybe other people here especially might appreciate it

user15026

11:48 PM

(I do apologize if it makes more people regret their lack of ice cream.)

HDE 226868

It's kinda cold for ice cream where I am. . . Hot chocolate seems better right now.

user15026

Yeah, we are supposed to get snow again :/ but I tend to like sometimes putting the ice cream in the hot chocolate. Like a float but better.
