| lucas_ai | What's a very fast browser for linux that I can use really fast with keyboard shortcuts, not much with the mouse? I wanna increase productivity. | 02:53 |
|---|---|---|
| sarnold | lucas_ai: a friend told me about this, but I couldn't figure out how to run it http://edbrowse.org/ | 02:56 |
| sarnold | lucas_ai: I use pentadactly for firefox, but it's chronically not functioning after firefox updates, and you have to run it from git... maybe search for it and then figure out something -else-. I can't, I'm too used to pentadactyl now. some day when I have to switch life is goign to be terrible for a few months. | 02:57 |
| hallyn | sarnold: i'm back to using vimperator (which pentadactyl was the new version of) | 04:53 |
| hallyn | it has a few downsides, but at least it always works | 04:54 |
| lucas_ai | I made a simple service and put it in /etc/init.d/potentialstudio ... why am I getting this error: Failed to start potentialstudio.service: Unit potentialstudio.service not found. | 05:10 |
| lucas_ai | I made a simple service and put it in /etc/init.d/potentialstudio ... why am I getting this error: Failed to start potentialstudio.service: Unit potentialstudio.service not found. | 05:48 |
| Seveas | lucas_ai: /etc/init.d is obsolete, make a proper systemd unit file. | 06:15 |
| lucas_ai_ | my systemd unit is working now, but how do I make it start when booting Ubuntu? when I do "sudo service potentialstudio enable", I get "potentialstudio: unrecognized service" | 07:27 |
| ikonia | that is not how you manage systemd | 07:36 |
| lucas_ai_ | ok... | 07:39 |
| ikonia | man systemctl | 07:40 |
| lucas_ai | I'm on Ubuntu server 16.04 with unity, and I can't log into an XFCE session. There's no option in the login screen! | 08:00 |
| lucas_ai | I literally can't find a way online. | 08:02 |
| lucas_ai | After installing xubuntu-desktop and rebooting, I have XFCE+Unity as default. I can't find a way to use gnome+Unity again. The settings icon in the login screen doesn't exist. Any ideas? | 08:23 |
| lucas_ai | How do I start my script or service when booting up? | 08:51 |

| alnr | i'm trying to patch openssl on xenial for CVE-2016-2107 (http://people.canonical.com/~ubuntu-security/cve/2016/CVE-2016-2107.html) my system reports openssl 1.0.2g-1ubuntu4.1 as newest, but the vulnerability remains even that that page purports that 1.0.2g-1ubuntu4.1 should cover it. is there a later version available? | 16:09 |
| patdk-lap2 | heh? | 16:14 |
| patdk-lap2 | how did you test that you are affected by cve-2016-2107? | 16:14 |
| patdk-lap2 | and did you restart your server, or atleast all services that use openssl after you upgraded? | 16:15 |
| alnr | patdk-lap2: i did restart the server. i'm using sslabs.com as the test. | 16:36 |
| alnr | ssllabls.com* | 16:37 |

| gbaker | I have a question about SSD's seem slow for buffered disk reads being in a raid0. Anyone have experience with this? | 18:12 |
| bekks | Define "seems slow" and elaborate on your benchmarking please. :) | 18:12 |
| gbaker | Just used hdparm and cached is 12149.30 MB/sec and buffered is 838.09 MB/sec | 18:13 |
| bekks | hahahahahdparm :) | 18:14 |
| cncr04s | sounds about right, I get up to 900MB/s reads | 18:14 |
| gbaker | yeah, but it's been a few years since I've been on a 1/2 decent machine. I have to leave MS... ugh on my desktop for app specific reasons :( | 18:15 |
| bekks | Then why do you use the most useless benchmarking tool ever? | 18:16 |
| gbaker | last time I was using linux not in a VM has been a few years... | 18:17 |
| cncr04s | you are unlikley to reach full saturation of your two 6G sata channels, mabye get sas drives or get a m.2 slot or pci ssds | 18:17 |
| gbaker | It's 4 m.2 drives | 18:18 |
| gbaker | I should state this is a laptop. | 18:18 |
| gbaker | So I do expect differences | 18:18 |
| cncr04s | then u got a problem, as good single m.2 ssd get me 2000mb/s+ | 18:18 |
| bekks | The DISK, not the controllers in a laptop... | 18:19 |
| gbaker | Thats what I figured. It should be faster | 18:19 |
| bekks | If you really want to benchmark your disk, use a benchmarking tool, and constraints that result in benchmarking the disk, not your memory. | 18:19 |
| bekks | Forget. about. hdparm. | 18:19 |
| gbaker | Suggestion on best one to try? | 18:20 |
| bekks | dd and testfile sizes larger than your RAM. | 18:20 |
| bekks | and a blocksize which is at least your filesystem blocksize. | 18:21 |
| gbaker | with dd it's 2.70247 s, 795 MB/s | 18:22 |
| bekks | "with dd". Which exact dd command did you use? | 18:22 |
| cncr04s | I have a feeling your slots are just using sata channels | 18:23 |
| gbaker | "dd if=/dev/zero of=/tmp/test1.img bs=32G count=1 oflag=dsync" | 18:23 |
| bekks | Cool, so you benchmarked your CPU. | 18:23 |
| bekks | You benchmarked how fast it can generate zeros. | 18:23 |
| bekks | and bs=32G is nonsense, since your filesystem does not use 32G blocks. | 18:23 |
| bekks | and oflag=dsync is even more nonsense, since you want to benchmark your disk, not synchronous writes. | 18:24 |
| cncr04s | dd if=/dev/zero of=/swap bs=1M count=1024 is what I use | 18:24 |
| gbaker | Just seeing most sites posting hdparm stuff still... Ill try that | 18:24 |
| bekks | You are benchmarking your CPU too. | 18:25 |
| bindi | dd bs=1M count=256 if=/dev/zero of=test conv=fdatasync | 18:25 |
| bekks | gbaker: millions of flies cant be wrong? :) | 18:25 |
| bekks | every benchmark using /dev/zero for reading will benchmark your CPU- | 18:25 |
| cncr04s | so what | 18:25 |
| gbaker | 268435456 bytes (268 MB, 256 MiB) copied, 0.312221 s, 860 MB/s | 18:25 |
| bindi | taken from https://romanrm.net/dd-benchmark | 18:26 |
| bekks | Benchmarking your CPU isnt benchmarking your dis. | 18:26 |
| cncr04s | but I always max my disk speed | 18:26 |
| gbaker | using bindi's command | 18:26 |
| bekks | create a file larger than your RAM using dd if=/dev/urandom ... - then benchmark your disk using that file. | 18:27 |
| cncr04s | creating random data is even worse then 0's | 18:27 |
| bekks | Yeah, and you arent benchmarking that file creation... | 18:27 |
| gbaker | Should I use something like double the ram? | 18:28 |
| bekks | gbaker: No. Just larger than your RAM is sufficient. | 18:28 |
| cncr04s | I never need to do that | 18:28 |
| bekks | Because you always benchmarked your RAM. | 18:28 |
| cncr04s | lol | 18:29 |
| cncr04s | no | 18:29 |
| cncr04s | ram speed is 20GBPS | 18:29 |
| cncr04s | or more | 18:29 |
| bekks | Did you benchmark that, too? :) | 18:29 |
| cncr04s | this guy | 18:29 |
| cncr04s | don't listen to him | 18:30 |
| bekks | Cool, the old strategy to tell people "dont listen to him" when running out of facts. | 18:30 |
| cncr04s | whatever file you create it has to end up going through the cpu and ram | 18:30 |
| cncr04s | so his points suck | 18:30 |
| gbaker | lol, every site has conflicting info. So I'm used to it :) | 18:30 |
| bekks | cncr04s: If you have no clue what I am talking about, how do you decide wether my point is wrong? That would be interesting to know | 18:31 |
| gbaker | I just felt that it seemed slow for 4 x M.2 drives but at the same time not many people are also doing this on a laptop either. | 18:31 |
| cncr04s | you don't have a clue as to what I'm talking about either | 18:31 |
| bekks | cncr04s: I do understand what you are talking about, but you are denying facts- | 18:32 |
| bekks | So there is no point in trusting you. | 18:32 |
| cncr04s | lol | 18:32 |
| gbaker | It's ok, I was sent over from #ubuntu because of my setup so it was more confusing over there. | 18:34 |
| cncr04s | gbaker: your speeds indicate a bottleneck in either your drives speed, but more likley the interface they are using, probably using sata channels. | 18:34 |
| gbaker | cncr04s: I believe that is the issue, but still seemed a bit slow. | 18:35 |
| cncr04s | I get around the same speeds with two ssds in raid0, they are sata 6G | 18:36 |
| gbaker | I first installed using mdadm as I read on several sites that it is the preferred way. But that seemed to reduce speeds. | 18:37 |
| gbaker | One more quick question... every post I've seen is about a year old or older for Nvidia and mobile gpu's for SLI. Has anyone ever heard if they ever plan on adding support for SLI for mobile gpu's? | 18:40 |
| cncr04s | what is the seed of one or two | 18:40 |
| cncr04s | btw using 4 drives in raid0 is just asking for trouble imho | 18:41 |
| gbaker | Yeah, but I use 5th drive for backup of /home and a few other directories. | 18:42 |
| gbaker | I did have it in raid 10 for a bit but it was a nightmare getting that set up.\ | 18:42 |
| cncr04s | raid10 is the best | 18:43 |
| gbaker | Yeah, but I was getting so many issues when I set it up. Kept having issues with having to install Nvidia drivers on live disk before I could start install or it would hang and after I figured that out I ran into several other issues. Took a week to get all of the tweaks I needed to do with getting that set up. | 18:45 |
| cncr04s | if your booting from it, you would typically set the raid up during installation, any sort of nvidia drivers don't apply to that step, not sure waht you mean | 18:46 |
| gbaker | On live disk I had to do it from the desktop installer. Using the desktop installer It took me a bit to figure it out but unless I installed nvidia drivers on the live disk and restart xserver then start install it would hang. | 18:48 |
| gbaker | Like I said. Getting this thing set up was an odd one. It's a laptop so I expected a few issues on getting it running and quite new hardware, but I'm fairly persistent. | 18:50 |
| cncr04s | mdadm -v --create /dev/md0 --level=raid10 --raid-devices=4 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1 | 18:51 |
| gbaker | On MSI's forums for this laptop I've only read a few that said that they were trying to install linux and couldn't find anyone that succeded. :) | 18:51 |
| gbaker | Oh I know how to create raid using mdadm. | 18:52 |
| cncr04s | your in ubuntu-server so I've never really used it for desktop purposes or with a gfx card | 18:52 |
| gbaker | I know but reg chan suggested server because of my setup was confusing to them. Not many laptops with 5 SSD drives | 18:53 |
| gbaker | and most couldn't answer raid questions. | 18:54 |
| cncr04s | my laptop only has one connector | 18:55 |
| cncr04s | its not that old lol | 18:55 |
| gbaker | This thing is a big beast. | 18:55 |
| gbaker | 18.4 inch screen... | 18:56 |
| gbaker | Should have seen me take it on a plane... It didn't fit in the x-ray trays. And TSA gave me some odd looks and made me fully boot it up. | 19:00 |
| cncr04s | my laptop was a waste of $ | 19:00 |
| cncr04s | I never use it | 19:00 |
| gbaker | I got a MSI-GT80-Titan-2QE and upgraded it quite a bit. | 19:01 |
| gbaker | Seems a bit much for a laptop but I was spending 75% of my time at my grandmas taking care of her because she is 93 and didn't want to feel like I was stuck on a laptop. | 19:03 |
| gbaker | I miss my old AIX admin days. | 19:04 |
| gbaker | Laptops last years for me, it's cellphones that seem to be a waste for my money. I can't get a year out of them before I do something stupid and break them. 2 months is my shortest time before I destroyed one. | 19:11 |
| cncr04s | I <3 servers, phones don't do server stuff, hold no interest with me. | 20:30 |
| gbaker | lol. I only use for that emergency call I've been expecting for several years. | 20:33 |
| gbaker | Last one I broke I had an audience and it was embarrassing. I accidentally drop kicked it across 2 lanes of traffic into a curb. | 20:35 |
| gbaker | Speaking of servers I picked up 40 nice server fans at a thrift store about a month ago for $5. Un used and boxes still sealed. | 20:36 |
| cncr04s | what kind of fans | 20:37 |
| gbaker | gfb1212vhw delta fan | 20:38 |
| cncr04s | i'll buy all 40 for 10$, a nice 100% profit for you. | 20:38 |
| gbaker | lol | 20:39 |
| gbaker | I want to keep a few and sell the rest. The airflow is great and they are fairly quiet. | 20:39 |
| cncr04s | I didnt think about noise when I got my 2u | 20:40 |
| cncr04s | the others I have are in server rooms so I don't care, but this one I got in my room | 20:40 |
| gbaker | Yeah, I usually don't pay attention until I had the old seagate 10k rpk scsi drives, sounded like an airplane taking off :) | 20:42 |
| gbaker | I kinda miss it but it could get loud | 20:43 |
| gbaker | *rpm | 20:43 |
| bekks | Have you ever heard a Oracle M5000 powering up - or a T7? :) | 20:44 |
| gbaker | I remember the IBM S80's winding up. I miss that. | 20:45 |
| bekks | The lovely sounds of an entire airport :) | 20:46 |
| gbaker | Yes :) | 20:47 |
| gbaker | I joked about that with a coworker when I said it sounded a lot like the M1 Abrams starting up back when I was in the Army. | 20:48 |
| bekks | Pretty quiet, those Abrams :D | 20:49 |
| gbaker | lol | 20:49 |
| gbaker | I really wanted to have one as a everyday driver, but they do eat quite a bit of fuel. But I wouldn't worry if people cut me off. | 20:51 |
| bekks | you wouldnt even notice :) | 20:51 |
| gbaker | After seeing a Humvee take more damage than the honda civic it hit on post I felt less secure about military vehicles. | 20:53 |
| bekks | Well, the Humvee is more like a limousine with camouflage. | 20:54 |
| gbaker | If that. The way the fan is set up for the radiator if you hit water anything faster than 2 mph the cheap plastic blades would break off. | 20:55 |
| bekks | Doesnt sound like a Skunkworks invention :P | 20:56 |
| gbaker | One of my best memories was learning how to use the old punch card programming... in the 90's. Only because they still had some operating. | 20:58 |
| gbaker | Scariest part was my dad was in some of the training videos, and he was quite a bit older than my mom. (13 years older) It felt like quantum leap. | 21:00 |
