Q: Add "To-Do" flag on Q&A posts, and "To-Do" list on review page

Often times I find I'm browsing through questions and answers, and I find a post that could use a bit of work but I don't immediately have the time to devote to correcting it. It's not something that really needs to be flagged for moderator attention - usually just some sort of formatting cleanu...

I've been doing that with favou?rites, but then keep forgetting to go back and check my favou?rites.

Blog - Stack Exchange: Stack Exchange Machine Learning Contest

Kevin Montrose on August 21, 2012

Over the last 4 years we’ve built up quite a bevy of moderation tools here at Stack Exchange. We’ve got closing, editing, deleting, flags of all sorts, voting, commenting, review queues, and more.

Plus our super secret mod tools.

These all work great, but all of them require action after a post is made. In a perfect world, we’d catch every post that ends up closed and deleted or voted down to a negative score before they ever showed up on the site. Less work for the community, less work for the moderators, and more consistent help for those unfortunate bad under-educated posters. …

And you're gonna be in trouble. Hey-yay, hey-yay Drew Smith is back!

Oh god no.

Jeff Ferland

@Polynomial What? Another Rory?

Polynomial

Andrew Smith is back.

So far he's posted one very short, slightly pointless question as a comment, and one pretty poor answer. Nothing crazy or paranoid, but not a great start.

Scott Pack

18:28

So we already have a fair number more people voting in this election than last.

I would hazard a guess that the two biggest voting times will be immediately when it opened, and immediately after the THC, but we're already at about 50% more involvement than last year.

Iszi

19:16

@ScottPack Eh? I thought those numbers were invisible until the end?

Scott Pack

@Iszi Funny story about that. The job that awards the Constituent badge runs every 5 minutes.

security.stackexchange.com/badges/93/constituent

We had 54 voters last year.

Iszi

Ah. So you can get numbers on how many have voted, and see who has voted, but not see the actual votes. This is all provided, of course, that participants don't already have the badge. So, your numbers for this year are probably a bit conservative.

Scott Pack

That's a neg. We've only had a single voting cycle.

Iszi

Unless, that is, you have a slick means of searching for badges awarded after a certain date.

@ScottPack Beg pardon? This is our second election.

Scott Pack

54 people voted last year. There are currently 144 users with that badge, therefore 144-54 is the number who have voted this year.

@Iszi Which is still happening.

Iszi

19:21

@ScottPack Presuming that none of the 144 also voted last year, yes.

Scott Pack

They'll show up twice.

Once for last year, and once for this year.

Iszi

@ScottPack Um... no?

Scott Pack

Uhmm...YES!

Iszi

Oh, I see how the view is.

Well, that's cool.

Scott Pack

So we're up to 90 voters in this election.

Rory Alsop

19:24

@ScottPack it's not him - it's all those churches claiming to speak for him

Scott Pack

@RoryAlsop Too shay.

I'm feeling like an idiot here. Can someone explain to me why this works: tcpdump -nn -r ringbuffer.1345575972 | grep 10.10.10.15

But this does not: tcpdump -nn -r ringbuffer.1345575972 ip host 10.10.10.15

Iszi

I don't have a *nix machine up to be able to man tcpdump for you just now, sorry.

Scott Pack

My non-working statement is syntactically correct, as near as I can tell, based on every version of the man page I've checked.

Iszi

Sure you're not missing a dash or something somewhere?

Scott Pack

`EXAMPLES
To print all packets arriving at or departing from sundown:
tcpdump host sundown
`

Well, that failed

Iszi

19:32

Wait... aren't most man pages online?

tcpdump.org/tcpdump_man.html

Scott Pack

Though not necessarily the man page for the version that you're running.

Iszi

Right...

Looks to me like you've got too many args after -r?

Scott Pack

Either way, that is, by the docs, a syntactically correct expression.

Iszi

Oh, wait. The rest of that is your [expression]

Scott Pack

Indeed.

Iszi

19:36

Well, crap. Now I need to find the PCAP filter man.

Scott Pack

pcap-filter(7)

Jeff Ferland

@Iszi quote the string

... nevermind

Iszi

@JeffFerland Thought that was right for a second after you said it, too. That's ok.

Scott Pack

NO IT'S NOT!

Iszi

What's -nn? I don't see it in the man.

Scott Pack

19:40

Don't resolve either IPs or ports

One n says don't resolve names, and the second does ports.

Iszi

Okay, so you want to do a tcpdump without resolving IPs or Ports, output to ringbuffer.1345575972 and filter it to only IP packets to/from 10.10.10.15?

Scott Pack

Well, reading from and existing pcap file.

Iszi

Ah, right. I thought it seemed weird to use "r" to specify output.

Scott Pack

-r for read. You use -wto write to a file.

Iszi

Well, the only difference I see between your straight tcpdump command and your grep filter is that grep doesn't limit you to IP packets?

Scott Pack

19:47

Strictly speaking, the ip could or could not be in there and I get the same results.

Iszi

That's what I thought, too. I'm guessing you've tried it?

Scott Pack

naturally

Now I'm trying a hex wise filter against those byte offsets in the ip header.

Iszi

So, you just threw that in as a red herring is that it? Asshole.

Scott Pack

When you pass an IP address 'host' and 'ip host' are functionally equivalent.

Iszi

That's what you think. But, tools can be... well, tools, with regards to such things.

Hey @nealmcb

nealmcb

19:51

@Iszi :)

Scott Pack

Hey @Neal!

Iszi

Hehe. I'm in an online training class right now, and the instructor just turned up Stack Overflow while trying to show us what kind of info is available on the Internet about the subject.

Scott Pack

I'm doing an online training that's being given by a Brazilian who looks full on Irish and sounds like he's from Minnesota.

Ah-HAH!

Vlans baby.

Iszi

@ScottPack What's that got to do with anything?

Scott Pack

libpcap is doing something stupid with the filters on tagged packets.

Iszi

19:54

So, what's that got to do with... Oh! Hrm. Cute.

Scott Pack

I have explicitly add the vlan id to my filter.

That is, tcpdump -nn -r ringbuffer.1345575972 vlan 100 and host 10.10.10.15

mfer

Iszi

Right. 'Cause otherwise you could totally end up finding packets from a 10.10.10.15 on another VLAN, I guess.

Scott Pack

20:09

This appears to be behavior introduced in newer versions of libpcap, for some definition of newer.

That is, I found it about 10 pages into a bug report for debian from 2005.

Iszi

@ScottPack Do you think this question could be more useful if we turned it into a general "looking for benchmarking tools" query?

Q: Computing RSA 1024-bit Decryption Performance

I want to be able to tell how many keys per second, using RSA 1024-bit keys, can be checked on a standard Pentium 4 system. How can I use this to determine decryption performance, and possibly remaining time?

brute-force

Argh. This instructor doesn't know the difference between GB, GiB, and Gb and it's giving me a headache.

When I'm asking for clarification of whether a command deals in GB or GiB, he thinks I'm asking "Gigabytes or Gigabits".

nealmcb

20:25

@ScottPack Howdy! And thanks for the election turnout numbers. It's pretty standard to provide turnout info before the close of polls. The risk though is that someone could contact user friends who haven't voted yet and "get the vote out". That is of course traditional also, but perhaps not conducive to the most unbiased outcome.

Evening all

Gilles

The human side of security: understand when you need rules and when you don't

Computers need to be driven by extremely precise rules, because they do exactly what you told them to do

Humans work differently

Jeff Ferland

@RoryAlsop Good $time

Gilles

Case in point: wanting to close each and every loophole in rules that are enforced post facto by a small group of human beings

Gilles

20:59

what's the file extension for powershell scripts (I assume that's how Windows recognizes them)?

Scott Pack

@nealmcb The biggest difference here is that we can see who voted, not just demographic figures of how many from where.

@Gilles Probably ps

@Gilles Just found ps1 according to the Googles.

nealmcb

@ScottPack You can almost always see, day by day, or via pollwatchers on election day, who has voted in government elections in the US also - that is how they figure out who to call to get them to the polls at the last minute

Scott Pack

@nealmcb Ah, good to know. I'm not sure I've ever seen that data before.

Gilles

@ScottPack wikipedia says .ps1

Scott Pack

@Gilles So wikipedia and google are in agreement. Must be correct, then.

To be fair, now that I actually look at my source instead of just the display context, my Google result came from a Technet article. I would consider them to be reasonably authoritative on Microsoft matters.

Gilles

21:04

@ScottPack yeah, and the DMZ was slower than googling. tssk

Scott Pack

No worries, I won't hold that against you.

Oy. Past quittin'. Have a lovely evening gentlemen.

Gilles

@ScottPack in France, the records of who voted is public (in principle, only to voters in the same geographical area), but it would be impractical to consult them while the polls are ongoing since they're on paper

Scott Pack

Also @Iszi.

Gilles

@ScottPack what about me?

Scott Pack

@Gilles Are you not a landowning male? If so my apologies for my unintentionally sexist remarks.

Gilles

21:07

@ScottPack oh, that meaning of gentleman

does an appartment count?

Scott Pack

I'll have to have my people check that.

Right then. Ta.

Gilles

happy $timeofday

@Gilles sharecropper

Iszi

@ScottPack Eh, what?

Oh, that.

In other news: A fringe benefit of working near the coast while living (relatively) inland is the prospect of having days off for hurricanes that aren't really going to affect you personally all that much.

Iszi

21:41

Ouch. I knew I never should have opened myself up for a morning slot when picking my schedule for the THC. 0800 U.S. Eastern on Thursday.

Scott Pack

I put thst down as an "if necessary" knowing that we had someone on like UTC+10 or whatevrr.

Iszi

@ScottPack Yeah, I think that's how I put it too.

Scott Pack

Feel bad for Mr. UTC-8 over there.

Iszi

I guess our majority of two just wasn't enough.

Scott Pack

I don't normally get much work done that hour anyway, what with coffee and email.

Iszi

21:45

Actually, we have quite a lot of UTC -5 (-4 this time of year, aren't we?) in the pool this time.

@ScottPack @bethlakshmi @JeffFerland and I make 4.

Scott Pack

Jeff is in California now.

Iszi

Oh.

@JeffFerland You need to update your profile.

Scott Pack

I expect him to be at just best at 5am. Just saying.

Jeff Ferland

@Iszi Bam. I have moved!

... 5am? Aww fuck

Scott Pack

I felt a great disturbance in the force when you crossed that river.

Jeff Ferland

21:48

@ScottPack I was moving pretty fast.

Scott Pack

Check your email?

Jeff Ferland

Not very much lately. Only with my phone. I don't get Internet at home until the 30th or I crack some neighbor's WEP key.

So I never did around to replying...

Iszi

@JeffFerland Ahhh... That's how this happened. IT'S ALL YOUR FAULT!

Scott Pack

Jerkface.

Gilles

@Iszi is that 12:00 UTC?

Iszi

21:52

@Gilles Ayup

Gilles

nice, I'll be able to attend

Iszi

Guess it's a good week for me to be in training. Normally, I wouldn't be able to make that kind of a date.

Jeff Ferland

Just so everybody's clear, if I'm there I'm naked.

Iszi

@JeffFerland Dude, it's not a video conference. We did not need to know that.

Jeff Ferland

@Iszi Well how else were you going to find out?

Iszi

21:58

@JeffFerland Who says we wanted to?

Jeff Ferland

Just saying... 5am... mean....

Of course, not putting that on my profile probably didn't help me any

Iszi

@JeffFerland And not responding to the e-mail...

Jeff Ferland

Hey man, I just got a place to live 4 days ago.

I don't even have a trash can yet.

Iszi

@JeffFerland A moderator can't afford to let little things like moving getting in the way of their service. ;-)

Jeff Ferland

<campaign> and that's how dedicated I am to this site, by the way... still here, checking /review, commenting, answering questions, and being in chat.... and I don't even own a damn trashcan</campaign>

Scott Pack

I would be disappointed if you weren't nekked, @Jeff.

@JeffFerland Yup

Jeff Ferland

@Iszi Trademark violation?

Scott Pack

I wonder if they should pay for the ad....

Iszi

@JeffFerland Hrm, is that trademarked?

Scott Pack

22:45

It's going to have a license of some kind.

Iszi

Think I should just nuke my post and e-mail the BT devs for their contribution?

Jeff Ferland

@Iszi Oh, your link actually points to their site... got it.

@JeffFerland Mouseover text is their slogan also.

It would at least be good form to ask.
