[02:53] 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. [02:56] lucas_ai: a friend told me about this, but I couldn't figure out how to run it http://edbrowse.org/ [02:57] 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. [04:53] sarnold: i'm back to using vimperator (which pentadactyl was the new version of) [04:54] it has a few downsides, but at least it always works [05:10] 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] 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. [06:15] lucas_ai: /etc/init.d is obsolete, make a proper systemd unit file. [07:27] 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" [07:36] that is not how you manage systemd [07:39] ok... [07:40] man systemctl [08:00] 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! [08:02] I literally can't find a way online. [08:23] 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? [08:51] How do I start my script or service when booting up? === Isla_de_Muerte is now known as NwS === JanC is now known as Guest71834 === JanC_ is now known as JanC === pavlushka is now known as Guest13413 === Guest13413 is now known as pavlushka [12:53] hi guys [12:53] when i try to install something i get this error [12:53] files list file for package 'linux-headers-4.4.0-31-generic' is missing final newline === hxm is now known as Guest32367 [16:09] 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? [16:14] heh? [16:14] how did you test that you are affected by cve-2016-2107? [16:15] and did you restart your server, or atleast all services that use openssl after you upgraded? [16:36] patdk-lap2: i did restart the server. i'm using sslabs.com as the test. [16:37] ssllabls.com* [16:37] ssllabs.com [16:44] also https://filippo.io/CVE-2016-2107/ [18:12] I have a question about SSD's seem slow for buffered disk reads being in a raid0. Anyone have experience with this? [18:12] Define "seems slow" and elaborate on your benchmarking please. :) [18:13] Just used hdparm and cached is 12149.30 MB/sec and buffered is 838.09 MB/sec [18:14] hahahahahdparm :) [18:14] sounds about right, I get up to 900MB/s reads [18:15] 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 :( [18:16] Then why do you use the most useless benchmarking tool ever? [18:17] last time I was using linux not in a VM has been a few years... [18:17] 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 [18:18] It's 4 m.2 drives [18:18] I should state this is a laptop. [18:18] So I do expect differences [18:18] then u got a problem, as good single m.2 ssd get me 2000mb/s+ [18:19] The DISK, not the controllers in a laptop... [18:19] Thats what I figured. It should be faster [18:19] 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] Forget. about. hdparm. [18:20] Suggestion on best one to try? [18:20] dd and testfile sizes larger than your RAM. [18:21] and a blocksize which is at least your filesystem blocksize. [18:22] with dd it's 2.70247 s, 795 MB/s [18:22] "with dd". Which exact dd command did you use? [18:23] I have a feeling your slots are just using sata channels [18:23] "dd if=/dev/zero of=/tmp/test1.img bs=32G count=1 oflag=dsync" [18:23] Cool, so you benchmarked your CPU. [18:23] You benchmarked how fast it can generate zeros. [18:23] and bs=32G is nonsense, since your filesystem does not use 32G blocks. [18:24] and oflag=dsync is even more nonsense, since you want to benchmark your disk, not synchronous writes. [18:24] dd if=/dev/zero of=/swap bs=1M count=1024 is what I use [18:24] Just seeing most sites posting hdparm stuff still... Ill try that [18:25] You are benchmarking your CPU too. [18:25] dd bs=1M count=256 if=/dev/zero of=test conv=fdatasync [18:25] gbaker: millions of flies cant be wrong? :) [18:25] every benchmark using /dev/zero for reading will benchmark your CPU- [18:25] so what [18:25] 268435456 bytes (268 MB, 256 MiB) copied, 0.312221 s, 860 MB/s [18:26] taken from https://romanrm.net/dd-benchmark [18:26] Benchmarking your CPU isnt benchmarking your dis. [18:26] but I always max my disk speed [18:26] using bindi's command [18:27] create a file larger than your RAM using dd if=/dev/urandom ... - then benchmark your disk using that file. [18:27] creating random data is even worse then 0's [18:27] Yeah, and you arent benchmarking that file creation... [18:28] Should I use something like double the ram? [18:28] gbaker: No. Just larger than your RAM is sufficient. [18:28] I never need to do that [18:28] Because you always benchmarked your RAM. [18:29] lol [18:29] no [18:29] ram speed is 20GBPS [18:29] or more [18:29] Did you benchmark that, too? :) [18:29] this guy [18:30] don't listen to him [18:30] Cool, the old strategy to tell people "dont listen to him" when running out of facts. [18:30] whatever file you create it has to end up going through the cpu and ram [18:30] so his points suck [18:30] lol, every site has conflicting info. So I'm used to it :) [18:31] 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] 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] you don't have a clue as to what I'm talking about either [18:32] cncr04s: I do understand what you are talking about, but you are denying facts- [18:32] So there is no point in trusting you. [18:32] lol [18:34] It's ok, I was sent over from #ubuntu because of my setup so it was more confusing over there. [18:34] gbaker: your speeds indicate a bottleneck in either your drives speed, but more likley the interface they are using, probably using sata channels. [18:35] cncr04s: I believe that is the issue, but still seemed a bit slow. [18:36] I get around the same speeds with two ssds in raid0, they are sata 6G [18:37] I first installed using mdadm as I read on several sites that it is the preferred way. But that seemed to reduce speeds. [18:40] 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] what is the seed of one or two [18:41] btw using 4 drives in raid0 is just asking for trouble imho [18:42] Yeah, but I use 5th drive for backup of /home and a few other directories. [18:42] I did have it in raid 10 for a bit but it was a nightmare getting that set up.\ [18:43] raid10 is the best [18:45] 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. [18:46] 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 [18:48] 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. [18:50] 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. [18:51] mdadm -v --create /dev/md0 --level=raid10 --raid-devices=4 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1 [18:51] 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. :) [18:52] Oh I know how to create raid using mdadm. [18:52] your in ubuntu-server so I've never really used it for desktop purposes or with a gfx card [18:53] I know but reg chan suggested server because of my setup was confusing to them. Not many laptops with 5 SSD drives [18:54] and most couldn't answer raid questions. [18:55] my laptop only has one connector [18:55] its not that old lol [18:55] This thing is a big beast. [18:56] 18.4 inch screen... [19:00] 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] my laptop was a waste of $ [19:00] I never use it [19:01] I got a MSI-GT80-Titan-2QE and upgraded it quite a bit. [19:03] 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. [19:04] I miss my old AIX admin days. [19:11] 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. [20:30] I <3 servers, phones don't do server stuff, hold no interest with me. [20:33] lol. I only use for that emergency call I've been expecting for several years. [20:35] 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. [20:36] Speaking of servers I picked up 40 nice server fans at a thrift store about a month ago for $5. Un used and boxes still sealed. [20:37] what kind of fans [20:38] gfb1212vhw delta fan [20:38] i'll buy all 40 for 10$, a nice 100% profit for you. [20:39] lol [20:39] I want to keep a few and sell the rest. The airflow is great and they are fairly quiet. [20:40] I didnt think about noise when I got my 2u [20:40] the others I have are in server rooms so I don't care, but this one I got in my room [20:42] Yeah, I usually don't pay attention until I had the old seagate 10k rpk scsi drives, sounded like an airplane taking off :) [20:43] I kinda miss it but it could get loud [20:43] *rpm [20:44] Have you ever heard a Oracle M5000 powering up - or a T7? :) [20:45] I remember the IBM S80's winding up. I miss that. [20:46] The lovely sounds of an entire airport :) [20:47] Yes :) [20:48] 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. [20:49] Pretty quiet, those Abrams :D [20:49] lol [20:51] 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] you wouldnt even notice :) [20:53] After seeing a Humvee take more damage than the honda civic it hit on post I felt less secure about military vehicles. [20:54] Well, the Humvee is more like a limousine with camouflage. [20:55] 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. [20:56] Doesnt sound like a Skunkworks invention :P [20:58] 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. [21:00] 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.
