Are you sure the SSD is a separately-addressable device? It may simply be an automatically-managed cache that's part of the hard drive. If that's the case, no action is needed; the drive will do all the work for you to optimize performance. — DragonLord 42 secs ago

Q: Linux partitioned for 8GB SSD + HDD?

I have a computer with 8GB of SSD storage, plus 1TB of regular hard-drive. I want to put the core of my Linux system in the SSD drive. I'll be mounting /home in the second drive, but what other partitions should I set up that way? How can I avoid running out of space, say, if I install something...

@HackToHell Ya, aware. Pretty screwy.

@DragonLord Dell has always been more enterprise than consumer, at least here.

@DragonLord That's just baseless speculation.

Even if you want to draw parallels to other companies, remember that Dell is privately owned.

Journeyman Geek

@Bob: and their hardware actually seems to be improving ;p

I believe newer Alienware machines are significantly more reliable than they were when Dell acquired them.

Of course, privately owned might make it easier for them to spin it off, but they might have less incentive to do so.

Okay I'm kinda starting to panic here

Journeyman Geek

PANIC! PAAAANIC

regedit doesn't show anything when I go to HKLM\SOFTWARE\Windows

Oh cancel panic. Gotta go to Microsoft\Windows

phew, almost thought there that everything was deleted

at least that gave me the chance to backup the registry

NTFS compression is surprisingly aggressive

1:24 AM

@oldmud0 ...a proper backup of the hives will do better.

Last I checked, you can't really treat a regedit export as a backup.

It won't import cleanly.

proper as in buy a $60 registry backup solution?

Also, it bloats the size quite a bit over the bare minimum.

@oldmud0 ...what?

oh ok, you're talking about copying the reg folder right

Proper as in backing up the relevant files => msdn.microsoft.com/en-us/library/windows/desktop/…

Though you're probably better off with a full system image.

Which many free backup programs can do, if you care about price.

blogs.msdn.com/b/oldnewthing/archive/2003/08/08/54618.aspx

Full system image? I don't even have a drive big enough for that, and uploading could take weeks

I'd prefer something less redundant

you know how you have all those 32gb SD cards laying around

just add a couple dozen SD card readers

Journeyman Geek

over USB 2.0? ;p

You're going to be bottlenecked by the USB interface.

1:41 AM

nah since we are already making modifications to the rpi we'll replace it with 3.0

This just isn't supported by the underlying hardware.

sure it's not, bring out your scalpel cuz we'll be surgically removing that cpu and replacing it with a haswell

I'd just get an NUC instead.

yeah sure ok that works

it's haswell too, and with usb 3.0

hmmm no pcie

figures, since that needs atx

holy cow, pentiums and celerons

Journeyman Geek

Well, not ATX

lol

celerons are high end atoms, until they rename the atoms, pentiums are low end cores...

except when a celeron is a low end core... ;p

also, its nothing to do with ATX

the raspi just isn't designed for it. You could build a raspi sized box with usb 3.0 and sata if you wanted to

just not at that price point.

1:49 AM

well only 3k for you to get to 100k

you should feel accomplished

you mean 30K

@Bob: funny thing is I've been less active this year than most

I'm not active enough for continuous rep (apart from the trickle from old posts), but I have a weird tendency to get really highly upvoted answers at times.

I made a bucket list a few weeks ago

So that I don't forget my crazy ideas like "Algorithm for transmitting binary data over lossy video"

Q: Is it possible to store arbitrary data in an image file?

Is it possible to store arbitrary data such as documents or a program in the form of an image file, such as a PNG image? My concern is that someone could encode data for use by malware into an image and upload it to a site like Flickr.

security images malware png

Wouldn't be much work to extend it to video.

@DragonLord Most of those answers discuss metadata in the image format.

Not data as part of the image itself.

Even then, video is considerably different - most video encodings don't work on a frame-by-frame basis, and there can be significant interpolation between frames, not to mention dropped frames.

2:45 AM

Exactly which is why it would be difficult to make such a thing

The goal of such a project would be to transmit data over a h.264 stream at a reasonable bitrate

For what purpose? I dunno. Academic, I guess

it would be like a more meaningful version of webdriver torso

@oldmud0 Depends what kind of bitrate you expect.

I mean, you could easily get 1bps by blinking the screen black and white every second :P

I dunno, but one that doesn't require high error correction

make it 60fps while you're at it

1500kbps vbr

throw in an AAC audio stream for error correction, 128kbps

4:36 AM

With all this experiementation with VNC lately, I've decided to use my old Nexus 7 as a simple VNC client.

I use this app (paid version)

shrug I just use RDP & the Microsoft client (on Android too)

a recent update changed the resolution though... it no longer uses 1920x1080

I haven't been able to set up an RDP server on my cloud desktop server.

xrdp works reasonably well, but I usually use Windows for anything graphical.

I'll see if I can get xrdp up and running. I'll use the Microsoft Remote Desktop client for Android.

Got my Office 2016 HUP key just a bit ago! :D

Pity the download link doesn't work... at all.

4:58 AM

Does xrdp contain an embedded X server? If so, what's the default display number?

Forwarded port 3389 over SSH on my Nexus 9. On trying to connect, the Microsoft RD client fails with error 0xd06. Seems to be a known issue: github.com/neutrinolabs/xrdp/issues/246

@DragonLord Ouch :\

They don't seem to do NLA either.

Well, the RDP client on Windows 10 has no trouble connecting to it.

This is weird.

Sadly, it seems to only be able to forward from a VNC session on the server.

I guess I'll just continue to use TigerVNC.

Microsoft Remote Desktop Client for Android returns this:

> Your session ended because of a protocol error. If this keeps happening, ask your admin or tech support for help.

Error code: 0xd06

Once again, known issue.

I guess I'm going to remove xrdp and use TigerVNC.

From the looks of it, it's more likely to be a bug in the Microsoft RD client for Android than one in xrdp.

5:21 AM

@DragonLord ?

@DragonLord From the issue comments, it's just general incompat. Not really a bug in either side.

xrdp doesn't seem to contain an embedded X server. Do I need to install the X.Org Server to do this?

If you want to be technical about it, with the MS client as teh de facto standard, xdrp should be the one evolving.

@DragonLord Dunno. Been a long time since I used graphical remote Linux.

I recall some fiddling with xsession and lxde.

So, probably yes.

> Xrdp uses Xvnc or X11rdp to manage the X session

2

A: What is X11rdp?

X11rdp tries to improve on Xvnc by forwarding X11 draw commands as RDP draw commands instead of simply wrapping a vnc bitmap stream in RDP. http://sourceforge.net/p/xrdp/mailman/message/19278796/

Too much work.

I'd just give up.

The idea of an X server that converts X11 draw calls to RDP commands is great, but there isn't something that works out of the box as of yet.

I'm going to continue to use TigerVNC. sigh

I already have shell scripts and configuration files set up to start up a VNC server with Xfce running on it with one command.

The TigerVNC server contains its own version of the X server which tracks the upstream X.Org Server and passes the contents of the display over VNC.

Look, I paid for the Pro version of the Android VNC client I use.

The "purest" remote desktop solution is to just do X11 forwarding and pass raw X11 draw calls from applications to an X server running locally, but that's awfully inefficient and highly dependent on round-trip latency.

I've done this with some success, but it isn't really usable over my slow DSL connection. Besides, while my server is hosted in Linode's Newark, NJ datacenter, which is reasonably close, the effect of latency is still significant and is strongly felt even on my college's high-speed, low-latency Wi-Fi.

VNC is much more usable over this connection, especially with the right encoding.

5:46 AM

@DragonLord ...that's exactly what X11rdp does

I know, but it would be a configuration nightmare.

To have successfully set up TigerVNC and then to throw out all this effort to run an RDP server is just not worth it.

@DragonLord In what way?

I really want to stick as close to the openSUSE repositories as possible to make upgrades easier.

6:11 AM

On the topic of Dell's acquisition of EMC, the largest M&A transaction in the history of computing: theverge.com/2012/2/27/2828339/dell-not-a-pc-company

Three years ago.

> Dell says it's 'no longer a PC company,' focusing on enterprise

Only a matter of time before Dell goes the way of IBM and drops out of the consumer PC business for good.

11 hours ago, by DragonLord

Dell is simply no longer a consumer computer company more than it is an enterprise computing company.

@DragonLord Again, pure speculation.

You're taking IBM as precedent.

IBM was in a very different situation.

More, it's one example out of many - others who have not gone the same path.

IBM had different roots, a different structure.

Dell might go down that path. They might not. There is just about zero evidence that anything will happen one way or another.

Despite all the time I've spent in the classroom learning about code (and even taking software engineering courses), I'm a complete n00b when it comes to software engineering in the real world. Agile, XP, DevOps, continuous integration, it just doesn't make sense to me.

Any pointers to get me started?

Journeyman Geek

IBM's been spinning off businesses for years too.

All this stuff, as I understand it, is meant to enable teams to develop and deploy functioning software in the least amount of time possible. But how does it work in practice?

10:53 AM

@tereško Eh, decent enough for ballpark numbers.

Detailed, direct comparisons aren't always available.

granted

In fact, they usually aren't available.

Synthetic benchmarks are bad, but they're better than nothing - and also better than the multitude of sites listing specs as if a direct comparison were possible.

I'd rather a (unitless) number showing measured performance than some site saying "hey this is 1.7GHz which is better than the 1.2GHz! 4 cores > 2 cores!"

@DragonLord I do not even know what DevOps is. Like with the cloud I can give a meaning to it. And tomorrow I will give it another one....

@Bob I got me a new 760. Power useage dropped a lot from my previous card, that is one thing NV did quite well.

@Hennes What was the previous card?

And how's performance?

AMD/ATI 5870

11:03 AM

Someone else is interested in that card and got in before me, so I guess I'll just have to wait and see if they take it or not.

Which switches memory to max frequency when you connect more than one display

@Hennes ...yea, different story entirely.

I'm using a GTX 560, which has a similar max TDP as the 760.

AMD is rather known for their power-guzzling cards :P

And power-guzzling CPUs.

I got this card because it was fast and low power (copmpared to the generation before it).
We have come a long way since (both AMD and NV)

Hm. In fact, it's hard to call anything from AMD in the last decade particularly power efficient compared to their competitors.

If you go far enough to compare with the P4... (but then, that was the P4's fault)

11:04 AM

They were better in the early 2000s (when Intel went all-in on NetBurst)

nods

And they did not do badly with opterons either.

But once Intel moved their memory controller on board and got much better IPC.... technically game over

They still make great CPUs for a lot of people though

E.g. all those parents at home who need to check email once per week and whose idea of a browser is that 'it is the google browser' (because that is its start page)

Those users do not mind the power bill. Shop prices give them cheaper PCs with AMDs

For desktop PCs in businesses (on 10 hours per day) the story will be different

And I am not even going to compare to the average user on this channel

As to performance: I did not notice any difference between this new card and the old card.

Even though it should be about 2.3 x as fast

@Hennes Well, I guess you wouldn't notice much in day-to-day use.

Aye. Esp if you do not play FPS.

I did buy 'darkest dungeon' lately. That is my average game

But power usage at idle has dropped a lot

@Hennes There are lots of non-FPS games that are very graphics-intensive :P

Hm. My phone just ran out of power in my pocket.

That was... unexpected.

Hmm... high battery usage in the last few hours, with screen off. Odd.

Hm. Lots of usage from Spotify.

Ehm, retroactive correction. Not 760, 960

Ah, here are my notes.

GTX 960
Drop of 41 Watt when desktop is idle!

Used to idle with a power draw measured at 153 W

11:16 AM

My current idle power draw is... Hmm. 200W. That's actually disturbingly high.

Last time I checked was 100-150W.

Something's not right.

marcusdoesstuff

OC'd?

Nah.

No OC here either

An old i7 920 is still fast enough for most things.

marcusdoesstuff

oh phones :D

i7-2600 here. Haven't really been limited by the CPU.

@marcusdoesstuff Phone's not overclocked either :P

Unfortunately I seem to have lost the battery logs when it shut down.

11:18 AM

I should be able to OC from 2.66GHz to 4.0GHz on this CPU.
(not tested, but the average CPU from this D0 stepping should make that)

Well, GSam did anyway.

At horrible power costs

Android logs point to Spotify..? shrug

I like the board in the tweet. Two coloured messages :)

4 tickets for using a mobile while driving in one day is just bad though.

Now if they only could take away the mobile (rather then the drivers license) for that.

Journeyman Geek

@Hennes: That would make sense

take it away, make em pick it up at the police station while paying the fine.

Not sure how the law works, but I guess something like 'impeding general safety' would do the trick

I dislike fines. They are huge for some people and others just do not care (or earn to much money to let it hurt).
I point limit on a driver licnese and the ability to revoke it would be great.

Which is something other countries already did, but where we (NL) lag

Doesn't NL revoke licences for excessive speeding? "If you break the limits with 30-40 km/h your offense goes to the state attorney, which may withdraw your license. If you break the limit with more than 100% the police can take your vehicle"

For excessive: Yes. Exceed max speed by 50kmph or more (after correction) and goodbye drivers license and here is your car back. We crushed it a little.

For low speeds: It is merely a fine

And in between: I actually have no idea

I tend to avoid tickets. Had once recently though (bah) and one about 15 years ago

But that was faulty parking resp driving 60kmph while overtaking a bus in a 50kmph zone
