I/O is more a bottleneck than computation speed
It takes some time to establish a reliable data tunnel through the card connector
consider that when you insert the card, you are basically booting up the on-board computer
how much time does it take for a PC to go from powered-off state to full respond-to-request mode ?
 
@ThomasPornin if you run a dedicated OS in ROM and only initialize one communication peripheral (a serial port)? Not that much
what kills you is running the 4th-stage bootloader, initializing the toaster, loading the 3d desktop wallpaper, ...
I wonder if the trigger is closing tabs
it doesn't seem to be switching between tabs

@Gilles Chrome runs fine here by the way. A few weeks ago I had trouble on Windows (low-end laptop), which turned out to be too many cookies
The only problem (but that's with Firefox just the same) is high RAM usage... Even 4GB fills up pretty soon nowadays, when I bought this pc it was plenty for everything
 
Luc
12:46 AM
Is "Chosen by fair dice roll. Guaranteed to be random." a reference to anything besides this xkcd? xkcd.com/221
 
12:59 AM
@Luc not that I know of
So I downgraded to Chrome 21, which didn't have this problem
it couldn't read back my session, so I manually opened my usual SE tabs
and I'm seeing the problem again :(
Conclusion: it's not Chrome, it's SE's code
 
Luc
@Gilles You can see what the page is doing with F12 > Timeline > Record
 
@Luc but which page is it?
according to the Chrome task manager, only the main "Browser" process is using CPU time
 
Luc
@Gilles Well if the problem appears on SE tabs, I guess any of those
 
and that corresponds to what top tells me
 
Luc
hmm
 
1:09 AM
@Luc I pretty much only have SE tabs open, I do the rest in Firefox
 
Luc
Whynot use FF for this too then?
 
@Luc because SE's JS tends to work better and faster in Chrome
or tended... maybe I'll switch to FF
I should probably get a recent FF if I do, because SE tends to suck big time if your browser is more than a few weeks old
 
Luc
I never had trouble with SE actually, any platform
 
I guess the right tool to investigate this would be xtrace
I do not relish the idea of xtracing chrome
well, gotta get up in 4½ hours
I'd better get some sleep
 
Luc
Lol, perhaps. Mondays off here :P
 
1:27 AM
@Gilles I noticed that chrome usually doesn't play nice on linux. Firefox works waaaay better. Chrome is a lot better than firefox on Windows and OS X though.
 
Luc
@TerryChia Mozilla didn't seem to care enough about the 1% to implement the minimalistic view for linux though (removing the title bar and menu bar, like Chrome and similar to IE9), another reason for me to switch to Chrome
 
@Luc I don't use linux to surf the web much, so it doesn't really bother me. i guess it can be annoying for regular users though.
still, FF > Chrome as far as stability goes for now.

A: How does duqu delete itself?

randomdudeI haven't looked at Duqu itself, but the usual procedure to do this is to spawn a process which deletes the running executable - so something like exec("rm " + argv[0]") would do the trick.

Should this be made into a comment? It doesn't answer the question at all.
It's like going to a password hashing question and answering with I think SHA-256 is a hash

Q: protecting encryption key while application is usig it

4r1y4nI made an J2SE application that uses AES (in CBC mode using BouncyCastle library) to encrypt application config file & some user provided files. I stored the raw AES key in a file and i'm holding it in a flash drive. for using the application the flash drive should be plugged to machine first...

Quiet in here. Almost, too quiet...
 
hey you ruined the streak, I was wondering how many hours we could go sans-post ;op
 
Of course, the response would have to be from a non-U.S.-ian.
I'm guessing everyone else on my side of the pond has the day off.
 
ahh is it a holiday over there?
 
Columbus Day. A Hallmark Holiday for me.
 
heh I lose track of even the UK ones these days, being self-employed means most public holidays are "things that happen to other people"..
 
3:38 PM
Then again, I suppose "Hallmark Holiday" isn't quite the appropriate term if it's not one generally associated with greeting cards.
@RoryMcCune Being a government contractor, most public holidays are "things that happen to just about everyone at work except me".
 
@Iszi well at least you get some peace and quiet :)
 
And a good parking spot for the day.
 
3:52 PM
Afternoon
 
@RoryAlsop it's 8mins to midnight. afternoon?! :P
 
@TerryChia Well, I've been up in the highlands and out of touch - just got back now :-)
It's great being somewhere I have no requirement to drive, and there is an ample stock of beverages...
 
@RoryAlsop beverages meaning alcohol? :P
 
...yep
 
this is Scotland afer all :op
 
3:59 PM
Cool, I am VERY close to earning a famous question badge on Arqade.
97 more views.
 
@TerryChia Seems to me, for some reason, that's the easiest site to do it on. I've got 3 already.
 
@Iszi I guess it is because of the users finding the page from google.
The vote/view ratio isn't very good.
 
4:39 PM
@Iszi My Columbus Day isn't until the 4th Friday in November.

Was just looking at the new web platform site, does their forums page remind anyone of anything... talk.webplatform.org/forums
 
It looks an awful lot like Question2Answer
 
I think it's based on that. Do they share a common heritage with StackExchange (which is what I thought it looked like...)
 
oh dear $deity
have you checked out their HTML?
ouch. all caps tags, links using . as a prefix, etc.
 
no, but I'm guessing from your impreciation that it's not as good as it should be :oP
 
well, all-caps tags is kinda 1999
they don't even have a proper doctype
and using ./path/to/link.php is kinda... eww
 
6:31 PM
yeah those aren't really the shiney HTTP/x.0 stylings you'd hope to see from a site like this..
 
I'd have liked to have seen at least XHTML 1.0 or HTML 4.1
rather than no doctype and HTML4.0-style 1999 caps tags
 
6:56 PM
@RoryAlsop Oh Hai Rory, any chance you can speak to the SE god and allow me access to the blog please?
Preferably as me and not whoever that scoundrel ninefingers-2 is.
 
He has 81 fingers.
 
@Polynomial Or possibly 7. Actually, he's me, it's just that since there's a wordpress account by the name of Ninefingers, the seAuthentiwhatsit relegated my real account to Ninefingers-2
 
^.^
I was thinking more along the lines of Ninefingers²
 
I just want to be myself, y'know! ;)
 
7:24 PM
@ninefingers - is on my list for this eve once I finish up being a taxi for the kids.
II think there is something I can do, and if not, I will bug rchern :)
 
@RoryAlsop Cool thanks!

A: What is the purpose of a fuzzer?

Sean W.A fuzzer is a tool that is used for finding vulnerabilities in software which may be exploitable by an attacker.

Stellar job!
 
well, it's certainly to the point!
 
The other guy answer just
... that's not a typo or shortcut. He finishes his answer with "and"
 
The side effect of the nice rise in users - the drop in average quality...
<big sigh>
still - loads of edit badges available :-)
 
And.

Q: By default, does a linksys router log connections?

AnthonyRouters have many settings that allow it to be safe and secure for the users that are connected to that network. A lot of these settings have to be manually configured though, which includes configuring the username and password to log into the router, cloaking the SSID, and so on. I began wond...

Q: What is booter ? ( means DDOS booter )

yakWhat is booter ? ( means DDOS booter ) when i read in google ... it means the control center to attack with post & get multi-request for DDOS . He is the main player for bot contorl . I wanna know more and more details .... plz explain me or not give me links to learn perfectly thanks U...

&A&D

8:50 PM
@DigitalFire Just following tradition :)
@DigitalFire Sorry, I'd like to provide you a better answer and hopefully when I have some free time I'll type it up.
 
@JeffFerland Thanks, That question does require sometime to appropriately answer it.
Seam W. has improved his answer here: security.stackexchange.com/questions/21305/… I believe he doesn't deserve the down votes anymore.
 
9:06 PM
@JeffFerland meh, it's not that bad. The other answer is worse than the edited version, and not that much better than Sean's original, yet it's at +3
After my Chrome woes I'm trying Firefox 15
working so far
 
Should I mark Sparr as the correct answer? I figured a few more examples would have been mentioned..
 
unlike Iceweasel 10 which mostly worked but made a complete mess of Ask Ubuntu for some reason
it's even pretty fast with MathJax, at least it's not markedly slower than Chrome
 
9:41 PM
@RoryAlsop not just quality, but level of effort in asking q's.
which goes back to quality, I guess...
 
yeah
 
Urgh. I am disappoint.
I write anwer.
 
I've been seeing a lot of questions lately to which the best answer would be LMWPTFY (Let me wikipedia that for you)
 
@JeffFerland my anwer betr than otehr awers, upvote make me the accept anwer I know security along and can needing help
 
while I dont think we need to set a minimal level of knowledge, experience or expertise to ask questions here, I do think we might start requiring the minimal level of effort (e.g. checking the basic wikipedia article first) just as expected throughout the SE network.
@RoryAlsop okay, and we'll make some semantically possible English a requirement, too.
That hurt my brain.
 
9:44 PM
@AviD agreed. I think we have enough of a core set of questions and users that we can start to be a tad more picky
@AviD It hurt my brian too :-)
 
@RoryAlsop you call it Brian?
and how in hell did you type with it??
 
hahahahahah - the only problem is hitting too many keys at once
 
@RoryAlsop cool. what would be the close reason...? NarQ? NC?
 
NARQ
On the basis it's incomplete
 
but... it kinda is. just really helplessly so.
 
9:46 PM
or not narrow enough in scope.
 
if we can't fully understand the question it implies it is incomplete, ne?
 
@RoryAlsop meant the WP q's, not the foreign.
 
oh, yeah, that too :-) NARQ will do fine - we don't really have a proper 'this question is too dumb' close reason
 
okay, cool. would require a comment to go along with it, though.
 
yup
 
10:12 PM
I'm writing a DHCP client. Yay for doing something that N other people have done before me.
 
so.... why ARE you doing that?
 
@AviD Because nobody ever wrote a good load tester for it.
Even ISC has it on their "todo" list
 
load tester for the dhcp client?
 
... and dammit, I need to request an entire Class A of IPs. At once. Every 10 seconds. Just because.
@AviD Hammer the DHCP server
 
I find it hard to see much load on that.
ahhh, right, of course.
sure, that makes some sense.
 
10:23 PM
Just a little. Only a little.
 
so its not a generic client, its a pseudo-client for server testing purposes.
 
oo, while you're at it, maybe build it to also fuzz the server and

Q: Need advice on using Wireshark + aircrack-ng

svzI am making acquiantance with wireless security and attacks and was told to run some tests with aircrack-ng and wireshark. So I installed both of them and ran airmon to switch wi-fi card to monitor mode: sudo airmon-ng start ra0 (this is my DWA-140 usb wi-fi adapter) The wi-fi adapter seems to ...

would benefit from Sec.SE expertise
maybe even should be migrated to Sec.SE? It's technically on-topic for us since he's doing the snooping from unix, but it's more about the network traffic and the behavior of various clients that aren't all unix

Q: Is it possible to have malware software in Linux without executing untrusted applications?

MiroI'm linux user and I'm thinking about it's vulnerabilities to malware. Can I get any malware if I run only trusted applications from distro's repository?

surely there's some existing Sec.SE thread we can point him to?
 
11:21 PM
@Jeff Why write a whole app when you could probably do it in two lines of perl. Well, 3 if you count use Net::RawSock or whatever
Ooo! echo -ne "${HEXOFDISCOVER}" | nc server 68

For the love of Scheneier, why??? — Gilles 8 secs ago
 
s/Schneier/all things good and Pornin/ There. I fixed that for you.
 
@ScottPack What do you think of the two questions I linked earlier?
 
I'll have to gander. I mostly popped online accidentally when I opened my computer to start working on a presentation.
