@bwDraco what do you mean by full user session?
 
Basically, root logs itself in, starting a bunch of services, runs the job, then logs out.
 
that doesnt sound right
 
It's more computationally expensive then I'd like it to be.
 
does it nee those services ruuning for its task?
 
Not really
 
6:04 PM
also concider nicing it
then u dopnt care how much computation it needs (within limits)
 
Not too sure why this is happening every 15 minutes, even with the cron job disabled:

yah thats not right
heh systemd so lord knowss
17668 what is this processs?
 
I've recognized the problem. You must uninstall the defunct systemd and replace with upstart.
 
Everyone uses systemd these days. Love it or hate it, it's here to stay.
 
even I do! :O
whats your favourite flavour?
blashphemy now you know where I don't live!
 
6:14 PM
Heay guys ^^
 
im clearly not everyone
 
wut
 
6:36 PM
As if disabling paste on the pass wasn't bad enough, they added a captcha.
One of the million tiny perks of being paid by a third-party government branch
 
well can't javascript read what's on your clipboard since it can very well write to your clipboard?
so disabling paste was not bad at all
 
!!facepalm
 
6:38 PM
Yes, it is!
 
@ChatBotJohnCavil !!65wat
!!65wat
 
I'm fairly certain JS can't read from the clipboard without producing a warning prompt from the browser
23
A: Get current clipboard content?

Davewindow.clipboardData.getData('Text') will work in some browsers. However, many browsers where it does work will prompt the user as to whether or not they wish the web page to have access to the clipboard.

 
only way to test if to find a website where you can successfully plant XSS and plant some JS to read the clipboard and insert the contents into the page in order to test this theory right??
 
Is it also okey to ask here rather smaller questions?
 
6:43 PM
like?
 
@Junaga Depends on the question. It usually is, if on topic.
As a rule of thumb, you should prefer asking questions on the main site
 
okay, then I won't bother you:p btw what are you guys doing?
 
Ask me a small question Junaga, don't worry about everyone else. You and I are just going to have a private conversation on this public chat :)
 
@Junaga Asking smaller, quick questions here is not frowned upon, specially if its related to the knowledge of one or more regulars.
 
at that brazilian guy I mean @ThatBrazilianGuy define, what is a regular?
 
6:45 PM
But keep in mind there are, at best, a dozen or so people here, aversus thousands on the main site
 
yes also keep in mind we have some of the top super user people here :)
 
@CausingUnderflowsEverywhere A regular visitor, someone who is frequently in the room
 
@ThatBrazilianGuy am I but a visitor to you?
 
You are now just curious about the question :D but okay here we go:
I'd like to know what is the common way the cpu talks to I/O
 
@CausingUnderflowsEverywhere To me, you're not a visitor ;p
 
6:47 PM
the cpu does not talk
question answered.
 
xD
 
@Junaga Hm, that's beyond my knowledge. But I suppose it's a few google searches away ;p
 
I read about memory mapped I/O so some of the adress space is signed to I/O but is that the general way it works today?
Guys, now really of topic. But does it bother you that not a single person alive knows HOW exactly a computer works? I mean completely to rebuild one form scratch
 
I have no clue how the internals of a computer work and I wish I knew,

soo....... power on -> some electricity goes into the cpu and for some reason it comes from the BIOS right?

Then some electricity goes into the boot device and then some electricity comes out of the boot device to the CPU right? then before you know it electricity is going back and forth from the boot device to the CPU and from the CPU to the RAM?

and then well a hard drive is I/O so there you go
at Junaga I believe that's an uneducated question you're asking there and I love computers maybe one day I'll be one of those people who knows exactly
 
@CausingUnderflowsEverywhere +1
xD
 
6:51 PM
@Junaga It amazes me a lot. It is a tiny bit scary and also a sign of the times we live
 
True that.
 
@Junaga Off-topic is the norm. Have you seen the room description? ;p
 
cucumbers
 
> For all you Super Users out there. Current topics: Technology, Taylor Swift, and Cucumbers.
 
On Topic: about cucumbers
has the internet gone to far?
 
6:54 PM
wat
 
wtf, this is actually a thing : i.imgur.com/5Lo376B.gifv
 
they are scared of snakes
 
makes sense
 
7:06 PM
lol
 
them to big. sorry I couldn't understand that segment, are you sure it is grammatically correct?

As if disabling paste on the pass wasn't bad enough, they added a captcha.
As if a captcha wasn't already bad enough.... The confirmation email hasn't arrived yet.

IT IS MY PAYCHECK GODDAAAAMNYA
 
how much is it?
 
@Junaga Are you asking how much I earn?
 
I earn nothing x) 20 years old studying, sorry okay:p I was just curious
 
7:14 PM
@Junaga I am not offended, just clarifying. I don't earn that much, about USD 850.
 
That's some good money.
 
@Junaga Depends on how much stuff will cost where you live. Less than a year ago, I was earning USD 600 and spending USD 200 on my health plan. Cool, huh?
 
sigh
 
where do you live? :o
 
That was scary.
Dropped my laptop, system shut down on impact.
Seems to be working now, no indication of any serious damage.
 
7:15 PM
poor little disk
 
Hard drive still works (that shutdown on impact probably staved off any damage; the heads may already have been parked as well.)
 
but maybe some bad sectors occurred better check dat disk
 
@bwDraco Yeah, on the weekend I accidentaly dropped my wife's laptop from the couch into the ground with a loud bang.
 
I'm most concerned about the optical drive, since the impact struck near it.
 
Same weekend she had her phone stolen =/
 
7:17 PM
Also I think ssds are know cheap af. My laptop turns on in like 5 secs
 
@Junaga Hmm. Where do I live. Now if there was any indication to that. Some sort of.... hint, maybe! ;p
 
The hard drive is still there even after the SSD upgrade for bulk storage. I'm probably going to run a surface scan.
 
Nope, SSDs are still very expensive
 
:(
 
Hello everyone
 
7:18 PM
There's a dent over a large area near the optical drive bay indicating the impact occurred. I'm surprised and thankful nothing got cracked or broken; the main service cover popped out but oddly enough was not damaged.
 
oh lol, your username doesn't get full displayed for me(I duno) but yeah that answers the question
 
New WhatsApp hoax going around telling women that a new section of the penal code allows them to kill men if they feel threatened :/
 
I've reseated the service cover and the machine is running. Both CPU and GPU fans run normally.
 
Guys, may I ask what OS/distro do you use? I'm just curious
 
@CausingUnderflowsEverywhere TCP does not guarantee the order, but it is capable of fixing out of order packets and requesting missing packets to be transmitted again.
 
7:20 PM
The impact was onto porcelain tile, which isn't forgiving, either.
 
@Junaga Windows 10.
 
Windows 10 Pro x64, Anniversary Update
 
same as benn
 
maybe your hard drive detected the free fall and docked its arm before the impact
 
7:23 PM
wasn't the anniversary update the one, that had the codename 'Redstone update' or something? Love that Minecraft reference, and the game
 
@Rahul2001 s i g h
@Junaga yes
 
@CausingUnderflowsEverywhere can disks do that?:o
 
@CausingUnderflowsEverywhere Not sure a WD Black can do that.
(stock hard drive: 750GB WD Black 7200 RPM)
 
@Junaga It was meant to be autocumbers ... :)
 
windows doesnt shut down if it loses access to the hdd though it freezes at most or bsods so not sure, unless you have auto restart. maybe when it impacted the battery disconnected or something briefly
yeah I saw that in a hard disks spec junaga.
 
7:26 PM
Optical drive seems to be working normally, can open and access disc contents as expected.
 
@Junaga Windows 7, 8, 10, Kali Linux
 
In all honesty, I'm impressed at how solidly these Clevo systems are built. I'm not sure whether a similarly-equipped Alienware 15 would have survived this sort of impact...
(This is a Clevo P157SM.)
 
@DavidPostill were these questions incorrectly answered then and does MINA say false things?

https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=71339

http://stackoverflow.com/questions/1691179/is-tcp-guaranteed-to-arrive-in-order#1691189

Of course I mean will my server application receive the data in the order the client code sent it. Ignoring what the back end is doing (IP stack, TCP etc)

When you say tcp is capable of re-ordering, do you guarantee that it always will?
 
@Rahul2001 Isn't Kali Linux this Hacker Distro that uses gnome?
 
@Junaga yes
 
7:30 PM
I had a client bring in an alienware with BSODs, turns out they put a graphics card in there that BSODs.. so I dont think dell alienware is good at all
 
Then again, this is a $2000+ machine we're talking about, not a bottom-bin, made-to-a-price-point laptop.
 
baking soda It's baking soda
not anything else
you know what sucks
 
@CausingUnderflowsEverywhere If the TCP stack has been correctly written it should. Note that missing packets may not be retrievable (that is the definition of packet loss ...)
 
Oh yes, I remember being on the website, and it said things like "Pro hackers use Kali" and the "trailer" that was like 2 mins, just showed one and a half minutes of the gnome desktop. And an encryption program xD
 
I should be equiping myself with nice black jeans and a dress shirt but it's 20C outside and I bike and I'm hearty so Im still equiping myself in shorts and a t shirt and Im old now and feel like I need to wear clothes appropriate for my age where do I find shorts appropriate for a man in his 20s
 
7:34 PM
@Junaga you can build a computer using dominos
 
@Burgi Or meat.
 
the software I acquire marks packets and tells me it receives one packet, and then 10 packets in the order they should be, but that chain was supposed to come before that one packet. Do you think RTS is causing them to come in out of order?
 
@Junaga Used for pentesting... And also showing off
 
correct, i'm just not sure what you find so worrying about it....
 
maybe the client sends the 10 packets while the network is down then sends the next one so my server gets that one, then a tcp RTS re-sends those 10 that never made it and so they come after ?

Q: How does TCP implement/guarantee in-order data transmission?

Stack CoderI was wondering how exactly does TCP implement in-order delivery. lets say this is list of events packet1 sent , ack received. packet2 sent , ack not-received. packet3 sent. packet4 sent. ack4 received. ack3 received. ack2 received. Can you describe to me what exactly happens sequentia...

@CausingUnderflowsEverywhere
 
thanks David you're awesome and a super user top reputation :D
 
<blush/>
 
Rebooted for a surface scan. This will take a while...
 
aw Draco you can do live scans now we're no longer in XP days remember?
OH
MY GOODNESS
THIS DID NOT JUST HAPPEN
I TOOK A BITE INTO MY PIZZA AND BAM
OUCH THERES SOMETHING SOLID IN IT
 
7:42 PM
You broke a tooth?
 
do you know how picky I've become from having bones and other objects in my sauasges and hot dogs
then I became less picky
THIS IS THE FIRST TIME IT HAPPENED IN PIZZA OMG I CANT EAT PEPRONI ANYMORE
 
I don't know why. It isn't that dramatic at all. But this hurts me personally. I feel really sorry. lol
 
I really hope it wasnt from the pizza
I successfully consumed the bread part without finding anything solid all thats left is the peperoni
 
7:46 PM
wierd youtube only shows ads when Im signed it guess I can never sign it
 
@CausingUnderflowsEverywhere Sadly not without locking the whole disk and interfering with apps that want to access it.
 
@CausingUnderflowsEverywhere if you use ABP you don't get adverts on youtube :P
 
@CausingUnderflowsEverywhere get an addblocker, lol. like ublock origin its really good
 
no like the in-video ads the ones that make you wait until you;ve watched the advertisement
 
7:54 PM
Disk check complete. Logging in...
 
thanks for the domino computer @DavidPostill I'm starting to understand circuitry now :)
 
> Volume D: (\Device\HarddiskVolume2) is healthy. No action is needed.
\o/
 
well that's definitely a bone piece that was in the peperoni :/ sigh......... oh well I doubt peperoni was even healthy. I guess I can replace it with bacon as long as they use actual strips and not those balls that one again can have who knows what inside of it
 
phew
 
8:09 PM
so how do I give myself therapy after this bone experience do I just say **** it humans can swallow bones it's no big deal!
OOOOOOOOO @DavidPostill is lego plastic a good heat conductor and remover though? :/
 
@CausingUnderflowsEverywhere I'm so confused./
 
what about shock resistance, like having a subwoofer next to the computer
what are you consfused about
 
Still very tense after this adrenaline rush.
 
@CausingUnderflowsEverywhere ` the stuff about pizza
 
I was eating pizza and there was something hard that could not be crushed by my teeth and it was a bone and I'm already very picky now I feel like I cant eat peperoni pizza anymore cause of the bone
 
8:20 PM
To lose your fear, I suggest make a request at /r/theydidthemath to calculate the chances of that happening. :x
 
nahhhhhhhhhhhhh
how does that guy get laptop motherboards for his bisnes?!?! I want to custom build laptops :(
he makes the lego computers using laptop mobos
 
The original Google server was partially built using Lego bricks...
 
Inspection of the laptop indicates that the chassis absorbed much of the impact force, protecting the other parts of the system.
...much as crumple zones protect the occupants of a modern car in the event of a crash.
 
8:38 PM
okay sure let's go with that
 
9:06 PM
First time in ages I ventured in a chat room other than here to try to get help. In a few minutes I've been callled retarded, accused of hacking, and told to "fuck you".
 
@ThatBrazilianGuy Oh dear. Which room?
 
9:41 PM

 JavaScript

Topic: Anything JavaScript, ECMAScript including Node, React, ...
Starts at :33154040 and ends at :33154394
The offensive part was right before "sorry, but i ain't helping you", but it was removed (only because I flagged it)
So much for "be nice", I guess.
 
@ThatBrazilianGuy Which browser?
 
Firefox. But I can use Chromium as well.
The damn thing made me more pissed than I should have been.
Maybe it's because of some bad stuff that's been happening since two days ago here at work.
 
@ThatBrazilianGuy Damn. I have a Firefox extension that "Prevents websites from interfering with copy and paste actions." but the author has removed it :/
 
@DavidPostill Do you have it installed? Can you extract the .xpi using FEBE?
 
9:55 PM
Hmmm... Sounds very promising!
 
locate dom.event.clipboardevents.enable preference item in Firefox about:config, and set it to false (default is true)
 
I'll try that and if it works, I'll write a question so you can answer it
 
Apparently it does the same as the extension. See image at the end of the link
 
IT WORKS!!!! :D :D :D :D :D
 
@ThatBrazilianGuy I hope that was a better experience for you than the one in chat.stackoverflow.com/rooms/17/javascript :)
 
10:00 PM
@DavidPostill what's your favorite beer and how I send it to you?
 
@ThatBrazilianGuy lol. you can buy me a beer next time I'm in BR
 
I'm not sure if I ever said that, but if / whenever any of the regular folks from here ever come to Rio, I'd be more than happy to pay any of you guys a beer! And I really mean it.
@DavidPostill But man, you have no idea how much stress you just saved me. I'd buy you a special, homebrewed beer.
Now I have to go, 7pm and the wife radiopatrol already rang :P
Bye and thanks again!
 
@ThatBrazilianGuy You're welcome
 
where is qwertyuiop/qasdfdsaq/etc?
 
Hm. I hope they are fine. Last time I heard they were in a hotel and looking for a place to stay.
 
10:06 PM
the room population has been waaaaaay down since i got back from holiday and i was wondering if that was coincidence?
 
@Burgi Not heard anything
@BenN lol
@Burgi "Last seen 11 hours ago"
 
shrug
 
@Burgi I've also been more scarce.
 
10:21 PM
must be the time of year
 
yes the weather, weather or not someone has something better to be doing :-)
@Burgi so do you feel all refreshed and ready to get right back to work doubling your effort after your extended and wonderous vacation? Or more like, wishing it was longer , much longer?
 
10:43 PM
i wish it was longer but only because i'm having trouble sleeping since i got back
speaking of which... nn
 
Good night!
 
good things to hear after you come back from work vacation:
Gesus! I thought you had quit, you gotta help me with . . . .
Get on that now, you have had your fun, now get back to work.
Heh, You should see what it's like when your not here.
 
Catty's been MIA lately...
 
Bad things to hear after you come back from a work vacation:
Do you work here, I dont remember seeing you?
I was hopeing you had quit.
We got a lot done while you were gone.

@bwDraco that's not nice at all
 
10:52 PM
...was unsure about that and ready to delete. sorry.
 
In other news, the small children in the computer lab messed with the Ethernet cables again, so I had to do the trace-all-the-wires thing again today
 
@BenN I think this is the universe telling you one of two things.
 
@BenN Time to label your cables? :)
 
Buy a label printer, or no more little children in the computer labs...
@DavidPostill jinx
 
We're planning on rewiring the whole thing soon; the cables are super old
Hopefully a label printer will be involved
 
10:54 PM
@JourneymanGeek Sorry, will be more careful next time. It was briefly checked but still wound up getting posted :\
 
<sigh>
 
superglue
 
@BenN That would help greatly.
If this computer lab is used routinely by children, you might want to work on physically securing the cables.
@DavidPostill ?
Not sure how you'd physically make Ethernet cables tamper-resistant...
 
@bwDraco I'm suffering from Deja Vu
 
Explain?
 
11:00 PM
@DavidPostill I think they're pretty good, IMO
and royalty-free, which is always nice
 
Did stop briefly, trying to avoid making a mountain out of a molehill. Let's continue normally.
 
@allquicatic lol. I wasn't thinking of that meaning :)
 
part of the purpose of twisting it to that meaning was to attempt to change the room subject
 
@BenN Is there a particular reason the children are removing the Ethernet cables?
 
@allquicatic Yeah, I saw what you did there
 
11:03 PM
I think they see cables with one end unplugged, so they think "this should go in here!"
And then, because these are unmanaged switches, loops are made
 
@BenN lol
 
@allquicatic No need to worry about this. I'm not letting this escalate.
 
no auto-sensing?
 
@BenN lol
 
Not on these, evidently
 
11:05 PM
If you're allowed to say: what model switches?
 
usually even simple layer 2 switches are smart enough to take care of that
 
we should have those kids visiting the White House instead, they might accidentally fix something.
 
I don't remember the model or even brand TBH

Q: What happens if an unmanaged ethernet switch is looped (connected to itself)?

JonathanI don't know much at all about networking, and I when I tried to find an answer to this online I found someone who posted a one sentence answer saying "It would cause lots of broadcasts and collisions." What would happen, if anything at all, if I were to connect an unmanaged network switch to it...

This might be of interest.
Just how old are the switches?
 
just how old are the kids?
 
11:11 PM
night all ...
 
Good night.
 
Pretty old switches I think
 
Stepping out briefly, got work to do.
 
@BenN get some cheap patch panels, and stick disconnected ends there?

Q: please help me before my pc gets Ebola

BlaseI have had my phone tell me I have many viruses on it in the past. I don't know if its true, but I'm sure it is. Now I have many photos of my son and other precious memories that I want to transfer to my computer before I get rid of the phone. If I just transfer photos and videos that I have ta...

Ebola ?
 
11:18 PM
lol
 
I think he should call a doctor and take the laptop to first aid.
and wear gloves. :)
And and tagged with [spreadsheet] cells.
 
Quick question: If I create a network loop with unmanaged switches, would I see the network interfaces on the affected computer(s) run at their limit due to a broadcast storm?
 
e-mail me, because i wont even be able to find the post later on.
 
Merely connecting the phone to the computer isn't going to result in infection. Unlike flash drives, Android devices communicate with PCs using a protocol called MTP, which does not allow code on the device to be executed by itself. You should just be able to transfer photos to the computer and factory-reset the phone. — bwDraco 1 min ago
(recovered cleanly and succeeded in avoiding drama \o/)
 
I wish my windows would do MTP. (win 10N).
 
The other computer here, works for the most part, but crashes with an error about every 2 days. I thought it was a driver. it errored with like 10 different errors, enough to indicate that none of the errors themselves would pinpoint the problem. slowly i was updating and changing drivers, assuming it was a leaking.
 
Not installing the bloatware pack
 
Found out last week, it all quit doing that , when i changed the power management for the PCI bus in windows ? so weird to have every error under the sun, and one button switched it from being DOA to living long happy life.
 
I choose the N version because I did not want to uninstall media player.
I just want to install a driver.
 
Bob
meh
 
11:30 PM
But most posts on the web are just 'install that media pack' or 'install samsung ki es"
First is not desired. Second fails to install until I installed that pack
 
Rewrote the question title.
 
Bob
Because the driver is only provided in that pack.
And it's not a arbitrary link either. It's fundamentally related to the rest of it.
 
Which means that for me windows 10 does not work with samsung phones.
I can alsways add a linux VM, or use a win7 host. (Which I do atm. move phone to w7 laptop, transfer files, move files to USB, plug USB in w10 compouter)
Uh, how is it related. All I want is a very simply driver to speak to an USB <strike>pendrive</strike> phone.
 
@Hennes Surround the text with three dashes: ---pendrive---
 
Bob
Because MTP is supposed to recognise (and potentially covert) codecs as you transfer them.
 
11:35 PM
!! s/\<.?strike\>/---/g
 
Yipes.
 
@bwDraco Uh, how is it related. All I want is a very simply driver to speak to an USB pendrive phone. (source)
 
i hate MPT, want my mass storage connect back, dont need anyone messing with the files , like they know better.
 
Bob
If you find it easier to hop to another system than simply not use parts of WMP you don't want, that's your choice.
 
YUp.
 
11:35 PM
(regex worked, yay!)
 
I only want to copy. Not have clippy interfere without my knowing.
 
that is where a removable chip in the phone comes in really handy, can be many times faster, and just copies. leaving out the microSD chip slot in some phones sucks double.
 
@Psycogeek The point of having MTP is that it's file-level and that the device can control the transfer of files. MSC requires block-level access, which would quite literally require the phone's OS to be shut down.
Also, Windows these days natively supports MTP.
 
of course it does, i expect next week it will deliver advertising while copying and do DRM checks :-)
2
some way they will find to make it more evil.
 
@Psycogeek ahh, they probably said that about the jacquard mill too. And the motorcar and....
 
11:43 PM
and rocks in pizzas :-)
 
Like anything, technology is a tool and is not intrinsically good or evil.
 
right it is how sony uses it to cost me 2 hours trying to find some software that acts like a virus.
 
Older virus exploited the fact that older versions of Android (before 3.0 Honeycomb) used MSC.
> Thankfully, however, this does not work for all devices. The attackers cannot use mobile devices that use the Media Transfer Protocol (MTP for short) and no longer make the internal memory available as an external mass storage device to transfer this malware. Here, however, there is a risk that a user could accidentally execute the Windows malware provided by Ssucl.A when he or she sees the files in Windows Explorer.
 
Hmm. So basically, if I put a windows virus on my phone,
use my phone as an USB pen drive
and click on the virus
And my windows virusscanner is out of date, only then I am in trouble?

Except a virusscanner on a PC is always up to date (I think that is a default setting these days)
 
Autorun is a possibility if it's a true flash drive (MSC). This shouldn't happen with MTP.
A low-level device compromise would be necessary to make this possible with modern Android devices.
 
11:56 PM
Autorun has been disabled on windows since, what was it, 4 years?
But yes, a good point
Personally my virusscanner is always up top date, so onlu new stuff would (should) infect me.
And I do not click on sexy_picture_of_$famous.jpeg.exe
And autorun is among the first things disabled after OS install
And blocked by the fileserver virusscanner at work (all autorun.inf auto deleted)
