@dunsmoreb I like the color choice but it doesn't appear to have a way to export the GPIO pins. The adafruit model has a slot for a ribbon cable.

dunsmoreb

@SteveRobillard True.

Steve Robillard

@dunsmoreb not to mention because they are only 75 miles away and the case is already done I will have it by next week the latest.

dunsmoreb

Coolio.

Q: What kind of HDMI cable do I need?

What kind of HDMI cable do I need if I want to connect my Raspberry PI to a full HD ( 1920 x 1080 ) TV (which has HDMI input)? According to the Wikipedia, there are 5 types of HDMI connectors: A, B, C, D, E, and several types of cables: Standard, High Speed, Automotive. Which one should be used?

Alex Chamberlain

@Jivings How come I didn't have to approve your edit?

finnw

Because he has over 500 rep

Alex Chamberlain

Oh, OK

Jivings

I'm a hero.

@AlexChamberlain I hope you were happy with my edit. I thought that needed to be emphasised!

Alex Chamberlain

That's fine. But I just got 500 rep, so be warned! :P

Jivings

Haha

Do we need a [tag: sudo]?

I can't imaging there will be many questions actually about sudo. Just answers that require it.

What am I doing wrong? sudo

Better.

Alex Chamberlain

11:57

I added, because I thought it might be added and I thought we could see how it developed

What were you doing wrong?

[tag: sudo]

[ tag: sudo ]

Jivings

Putting a space after tag

Alex Chamberlain

I've just hit the rep limit for today :(

[ tag : sudo]

Jivings

I'm on 90 and I've not answered any yet.

Alex Chamberlain

That sucks, how can I catch you up?

finnw

@Alex: the +15 from accepted answers is immune from the cap

as are bounties

Jivings

11:59

I'm going to put a bounty on one of my questions at some point.

Otherwise no-one will ever answer it.

If I can't solve it today I will bounty it up.

Alex Chamberlain

@finnw Out of 19 questions, only 1 of mine has been accepted

3 of those questions were my own in all fairness

Jivings

Hah

finnw

12:38

I think this is off-topic:

Q: Why do I have to `sudo`?

I've followed a couple of tutorials on my RPi and a lot of commands start with sudo; what does it mean and what does it do?

debian cli sudo

As useful as it may be, it is not RasPi-specific.

Alex Chamberlain

There is a little debate on the meta thread

A few of us agree, however, that we need to be friendly to questions from beginners

Jivings

If I'm answering a question and it requires the user download a file from a specific location, how do I deal with linking to that file?

finnw

But we don't want to have our own duplicates of every linux beginner question from the U+L site

Alex Chamberlain

@finnw As such, I think it is more appropriate to link to other SE questions, rather than merge them away from RPi.SE

@Jivings What file?

Jivings

It's a kernel image.

Alex Chamberlain

12:41

Send them to the webpage, rather than that link

500Mb download by accident isn't cool

finnw

Even if we have the most common ones (i.e. the ones that make it into our FAQ), I think they should be closed/locked.

Alex Chamberlain

Locked, yes

Can we put a high rep requirement on the locked questions?

finnw

that's called "protect" but that is not what I meant...

Q: FAQ for Stack Exchange sites

Community FAQ For sites in the Stack Exchange 2.0 network To see a list of commonly used words and phrases, see the glossary. Asking questions How do I write a good title? How can I get answers fast? Is there a limit on how many questions I can ask? How should we deal with Google questi...

support faq

There's "closed", "locked", "deleted" and "protected". They are all different

Only moderators can lock. The others can be done by voting.

Also, closed questions are not necessarily deleted (that is another common point of confusion)

Jivings

They should be locked.

Alex Chamberlain

They should be protected

Jivings

12:50

:-D

I think you're right, having read the FAQ. Protected makes more sense.

Alex Chamberlain

I look forward to trying your QEMU answer later

finnw

I think they should also be closed (but not deleted) because new answers are unlikely to be helpful

(and maybe locked in future, if they get reopened/closed repeatedly, which they might.)

Alex Chamberlain

We'll see how it goes

When someone becomes a mod, they can protect them

Q: Is the RasPi a suitable dev environment?

I don't have a linux box at home, so I'd like to use my RasPi to try out some development on linux. Is it fast enough to cope with this? Will binaries compiled on it run on other, more standard linux boxes, or will they only run on the RasPi?

software-development

Not constructive?

One could explain how to build a version of GCC that will cross-compile to X86...

But the question is mostly "is it suitable/fast enough." My guess would be no, but that's subjective

Jivings

It depends on the question.

If he wants to run an IDE, then probably no good.

Alex

13:37

@finnw Ha I got a notification for this. Hello!

finnw

I think that's a bug (I said it to the other Alex)

I expect when I say "@Alex" you will both get notifications :-)

even if you have not been in this room for 10 years

Alex

That could be annoying on SE or a more popular chat. Raise a ticket? :D

Jivings

The other Alex is @AlexChamberlain

finnw

@Alex re the sudo question, keeping it open is not the same thing as keeping the question (i.e. not deleting it.) I voted to close because it should not keep receiving new answers (but not delete because it should remain up for users to find.)

Jivings

@finnw I agree

Jivings

14:00

@finnw But again, that's @AlexChamberlain you want. Not @Alex.

Alex

I think we should give questions a bit more time to pan out

Instead of closing, we should change the scope slightly

finnw

@Jivings: No I did mean @Alex (he recently commented on that question)

Alex

Or post it meta and reach a verdict

Jivings

Oh okay

finnw

There's already a meta question about that

Q: Linux Questions: to close/migrate or to accept

It's apparent already that there are going to be a lot of questions relating to basic setup and accomplishing certain tasks within Linux. A choice we're going to have to make is whether to close/migrate these questions or to accept them as part of the community. Traditionally I believe that SE ...

discussion on-off-topic

I agree with Robert Cartaino's answer.

Alex

14:07

I agree with Cade Roux's answer :)

Alex Chamberlain

I get notifications for both @Alex and @AlexChamberlain

Jivings

Odd

Alex

I don't think we should accept meta questions so soon

dunsmoreb

I agree.

Alex

There are at least a hundred members on the site, and it was accepted with only three upvotes

dunsmoreb

14:08

Probably because he is a mod...

Q: Is the RasPi a suitable dev environment?

I don't have a linux box at home, so I'd like to use my RasPi to try out some development on linux. Is it fast enough to cope with this? Will binaries compiled on it run on other, more standard linux boxes, or will they only run on the RasPi?

software-development

Should we edit this to remove the subjective parts?

Jivings

Which parts are subjective?

dunsmoreb

> Is it fast enough to cope with this?

And the title is also subjective.

Jivings

Yeah I guess. Propose an edit

Alex Chamberlain

How do we remove RPi from the title?

dunsmoreb

I'm writing an edit right now.

There seems to be only one non-subjective question.

> Will compiled binaries run on other Linux boxes?

Would the cross-compilation apply to this question?

finnw

14:14

I initially thought that, but I don't think he really wants to cross-compile (that is taking it too literally.)

Jivings

I don't think so.

dunsmoreb

Okay.

There.

2

Q: Will compiled binaries run on other Linux boxes?

I don't have a linux box at home, so I'd like to use my Raspberry Pi to try out some development on Linux. Will binaries compiled on it run on other, more standard Linux boxes, or will they only run on the Raspberry Pi?

software-development

Alex Chamberlain

You have just changed the question!

Alex

Agreed, you ruined everything again

:P

dunsmoreb

That was the only non-subjective question in there.

Jivings

14:16

I've deleted my answer as it no longer applies.

finnw

Yes, I've deleted all but one line of mine

Jivings

haha

finnw

berry120's answer now looks out-of-place, even though it was a good answer to the original question

Alex

If I'd like to make a question searchable by either the 'emulation' or 'emulate' keyword, should I edit it to add the missing keyword?

finnw

The emulation tag should be enough to let people search for it

Alex

14:20

I think the search index must have refreshed or something, because before when I searched "emulate", my question didn't appear

7

Q: Emulation on a PC

How can I connect an SD card containing a Raspberry Pi OS to my PC, and boot the OS in an emulator? Why won't VMWare work? What are the limitations?

boot emulation

finnw

Google will find it anyway, if the user enters "emulate"

Alex

I mean in the site search, I think the site is still invisible to the outside world

finnw

But it will only be invisible to the outside world for a couple of weeks, after which it will not matter

Although it allows users to search before asking a duplicate question, we cannot rely on them to do that

Q: Can I stream 1080p video from the Pi?

We all know the Pi can play 1080p video no problem, but is it fast enough to act as the basis for a file server that can stream 1080p video over its wired network connection? I'm thinking of using mine as a media server of sorts to stream 1080p HD video (with DTS-HD audio) and interested to know...

video media media-server

I'm not sure about this one - I think it would be better on the forum. Not constructive?

Alex

I think it's possible to answer conclusively with a benchmark

finnw

Whatever the answer, the same would apply to any question of the form "Is there a project that does X"

Actually no, it follows a different pattern....

"Is the RasPi fast enough to do X"

Alex

14:30

I think "Can the Rpi do this?" questions are going to be asked

dunsmoreb

Those questions will be fun.

Alex

How can I install world of warcraft? I can't see anywhere for the CD...

dunsmoreb

@Alex That is a tough one.

It is not subjective so it could stay...

@finnw

0

A: "Is the RasPi fast enough for <*some task*>" questions

If the question was phrased, such as. Is the RPi fast enough for X? Then I would say close it as subjective. Just because people's idea of fast differs. What may be really fast for me, I only get a 10 Mbs Internet connection, may be really slow for you, you get a 200 Mbs Internet connection...

Alex

@dunsmoreb Jinx!

dunsmoreb

@Alex Actually no. I answered it 16 seconds before you. =P

Alex

14:38

Upvotes all round!

dunsmoreb

Haha.

Alex

Can I flag answers as duplicate?

:P

dunsmoreb

I would just VTC as duplicate.

That way we can actually get something done. =P

finnw

No, not answers, only questions

dunsmoreb

Oh. Didn't notice the answer part...

I feel like this question is off-topic.

3

Q: Why do I have to `sudo`?

I've followed a couple of tutorials on my RPi and a lot of commands start with sudo; what does it mean and what does it do?

debian cli sudo

> Is the crux of the question primarily about Raspberry Pi? Or is it a larger concern best answered elsewhere?

According to Robert these types of questions are off-topic.

finnw

14:49

I agree (I already voted to close that one)

We discussed that one earlier...

and I think we agreed that it should stay up (searchable) even if closed (no new answers accepted)

And so that we have something to link to if someone else dupes it later

dunsmoreb

Cool.

Alex Chamberlain

It will be duped daily...

finnw

I just added performance to those posts I linked in my meta question

dunsmoreb

Agreed.

Alex

What are everyone's thoughts on this?

I don't think this makes a good question, because it is effectively "please run a benchmark for me" or "please google for benchmark results for me." — finnw 15 mins ago

(I meant the whole question, not just that comment)

dunsmoreb

14:57

The question might be helpful. =P

Alex

2

Q: "Is the RasPi fast enough for <some task>" questions

Should such questions be considered on-topic? This is a pattern that has been repeated in a few questions now. Examples: Can I stream 1080p video from the Pi? What kind of performance can I expect from using a Pi as a webserver? Running 1080p video from within X.Org smoothly Is it possible to...

discussion close-reasons performance

I thought it better to discuss here than huge comment chains

dunsmoreb

I already answered the question with my thoughts on that.

I think benchmark questions should be allowed to stand.

Alex

What are your thought on the comments on my answer?

I think it's important that questions be on topic, answerable, and useful

It's difficult to draw a line between "Is the Raspi fast enough to render video?" to "Is the Raspi fast enough to handle DHCP for a network of 1000 users?"

finnw

Ok let me throw a spanner in the works here - "If DOOM 3 was ported to the Pi, what would its frame rate be?" :-)

In theory that is answerable.

Alex

So we wait and answer it in 30 years when DOOM 3 is released and ported?

I see where you're coming from

I guess the question has to be relevant to a large audience?

finnw

15:10

It's more that to answer it requires a large development project

Alex

So we can only accept easy questions? :P

dunsmoreb

Does this title make sense?

> Is it possible to immersively cool a device?

finnw

Yes (well I think I understood it)

dunsmoreb

I think it sounds weirder than the original...

Alex

> Is it possible to cool a device by immersion?

dunsmoreb

15:17

I don't know why, but a device just sounds weird to me...

Alex

> Is it possible to cool a Raspberry Pi by immersion?

dunsmoreb

Si.

I like that one better but I think people would disagree with me.

Alex

I think it's called "Liquid submersion cooling"

rather than immersion

Computer cooling

Computer cooling is required to remove the waste heat produced by computer components, to keep components within permissible operating temperature limits. Components that are susceptible to temporary malfunction or permanent failure if overheated include integrated circuits such as CPUs, chipset, graphics cards, and hard disk drives. Components are often designed to generate as little heat as possible, and computers and operating systems may be designed to reduce power consumption and consequent heating according to workload, but more heat may still be produced than can be removed wi...

> Is it possible to liquid submersion cool my Raspberry Pi?

I can't think of a way to remove the noun from the sentence

dunsmoreb

I'm just going to leave it.

I have to leave for Drill Practice.

I probably won't be back on until tomorrow though.

Which one?

Jivings

Any will do :)

I'd prefer this one raspberrypi.stackexchange.com/questions/14/…

Jivings

Haha, I actually had a spare that I gave to a friend.

Eh. I'll probably get a ModMyPi or whatever that link was that someone posted yesterday...

Jivings

17:41

Yeah, those are cool.

dunsmoreb

Ikr? =P

Jivings

What?

dunsmoreb

Ikr = I know right?

Jivings

Ah.

I wanted to be able to see the pi though. Do they have transparent ones?

dunsmoreb

The link that was posted did... Let me see if I can find it...

Here you go. adafruit.com/products/859
