Ask Slashdot: GPU of Choice For OpenCL On Linux?

DeHackEd nVidia w/ binary driver works (109 comments)

Using the binary driver has been fine for me.

Not much more to say on the matter. ffmpeg + x264 make use of it nicely.

Is Kitkat Killing Lollipop Uptake?

DeHackEd That includes me (437 comments)

My own impressions of 5.0 haven't been too good. The lockscreen doesn't give you the unlock input (eg: PIN) without pushing a button to ask for it, the animations have been stepped up -- the kinds of animations you can't turn off from the Dev menu -- and it generally looks copmletely childish. That's not what I personally want.

If you're running 4.4 check out all the new Google apps from the store. That's what you're getting from Lollipop, but also with the launcher, etc. No. No no no. I uninstalled the gmail update as fast as I could.

This is the trend in tech - things become more colourful, flat and generally dumbed down. I don't mean dumbed down from a user knowledge point of view, I mean "UI designed in MS Paint" down.

EU Court Rules Embedding YouTube Videos Is Not Copyright Infringement

DeHackEd Re:Crazy EU logic (again) (68 comments)

In the embedded scenario the owner retains control. Frankly said owner should simply disallow embedding and let the embedder look like an idiot until they realize what they did.

Systemd Adding Its Own Console To Linux Systems

DeHackEd Re:Why do people care so much? (774 comments)

https://bugs.freedesktop.org/s...

Indeed, I misremembered that. They don't say delete, they say the file gets rotated out immediately. And this bug report is famously linked as a demonstration of why systemd is hated for its developer attitude to the point that Lennart repsonded to it (today oddly enough). Corrupted files are not considered a bug and not getting fixed.

Systemd Adding Its Own Console To Linux Systems

DeHackEd Re:Why do people care so much? (774 comments)

[Disclaimer: Yes I hate systemd and I proclaim that loudly. Everything below is my personal experience with systemd and why I hate it.]

If booting the machine up was all it did, then I probably wouldn't care. Most of my hate (I can't speak for the rest of the internet) comes from the fact that systemd does a lot more. It also tracks user logins using a mechanism (control groups) that isn't available in some container scenarios making systemd unusable in those environments (and by extension any distro mandating systemd). It does its own logging in binary which needs a tool to read the logs and if it gets corrupted then systemd's devs say "just delete the logs". Really?

But I think the best reason people hate it is because it makes other applications become dependent on it. GNOME is the most well known example but I've also seen that Centos7's Source RPMs have systemd-specific commands (macros?) making it hard to build them on other platforms. rsyslog doesn't listen on /dev/log because systemd is doing something with the socket now. You cannot start services without systemd being the one to do it.

This is the hate. systemd isn't just an init system, it becomes part of your daily life. I liken it to the MCP (Master Contrl Progam) from the first TRON movie. It's systemd's way or the highway.

Fork of Systemd Leads To Lightweight Uselessd

DeHackEd Re:Finally someone decides to do something (469 comments)

Ordinarily I would agree, but systemd's "MCP-like" behaviour (TRON reference, I honestly believe that's a valid simile) means that uselessd has a chance of being a replacement for systemd packages of existing distributions. If I can put this in place of systemd on centos7 and have it boot in an unprivileged container (currnetly impossible with stock) then that's a win in my book.

You can't just switch systemd for openrc in an existing distribution without some major resistance. Believe me, I wish it could or I would just install openrc or upstart. That's the problem - systemd is claiming distributions and the list of alternatives is unnervingly small.

X.Org Server 1.16 Brings XWayland, GLAMOR, Systemd Integration

DeHackEd Re:Systemd? Not on my system... (226 comments)

Here's a true story. I was in a CentOS 7 system via chroot and trying to troubleshoot some problems. If it were CentOS 6 I would just run "service rsyslog start" and have syslog running in the chroot so I can get the diagnostics I was expecting, but since systemd wasn't actually running I couldn't do that. I had to launch rsyslog directly by command-line, but then it didn't listen on /dev/log like it's supposed to and I had no logging. After all, it's systemd integrated now and gets its listen socket a different way. And this is just the most recent incident.

Systemd may be technically better than sysvinit but the latter is just shell scripts which are sufficiently independent of anything else and just work. Systemd takes over your machine and wants to get its hands into everything to the point that you can't even use it anymore without systemd. This is what we're worried about what will happen to X.Org and other software.

Red Hat Enterprise Linux 7 Released

DeHackEd Re:Not the same LXC (231 comments)

I guess I didn't explain that very well.

Libvirt provides its own container launcher under the name "lxc". As I understand it this software is developped and maintained with libvirt. This is different software from the standalone project known as "LXC" as linked in the article.

Red Hat Enterprise Linux 7 Released

DeHackEd Not the same LXC (231 comments)

There's two projects named "lxc" - the one linked in the article ( https://linuxcontainers.org/ ) and one that's part of libvirt as a hypervisor driver. RHEL 7 includes the latter.

Now, time to download it and see how much has changed since the RC.

NFTables To Replace iptables In the Linux Kernel

DeHackEd Re:drunken troubleshooting in 3 years (235 comments)

> [root@wang]# iptables -F

Suddenly your INPUT chain policy of DROP kills all traffic and your ssh session drops. (You do have a default policy of DROP, right?)

Seriously, don't do that on an unknown system.

(I post this because I've had vendors' support try to remedy problems by disabling the firewall. :/)

The FCC Says ISPs Aren't Hitting Advertised Speeds

DeHackEd Sync vs Useful rates (228 comments)

I know DSL, being an ATM-based technology and often subjected to PPPoE overhead, will score lower than rated. I have a 5 megabit connection but that's the sync rate. You can realistically expect to lose 9-10% just from the above overheads. That rather fits with the graphs I'm seeing.

I've seen some ISPs compensate by setting the sync rate above the advertised rate but most don't.

Apple Laptops Vulnerable To Battery Firmware Hack

DeHackEd Write protect required (272 comments)

I would argue that everything with writable firmware should have some kind of jumper on it (default: on) to write protect the firmware. Thus you can only patch firmware by inserting a jumper on the right pins.

Still, anyone should think twice before being told "short these contacts on your battery in order to enable firmware updates."

Build Your Own 135TB RAID6 Storage Pod For $7,384

DeHackEd Re:Again? (239 comments)

Ugh, replying to myself. I missed the link in the post.

But nothing's changed, right? It's the same chassis, same diagrams from backblaze. Only ~2 years of bigger drives is new.

NESBot: Tool Assisted Speedrun On Real Hardware

DeHackEd Re:Ok, what? (101 comments)

Not officially, but collision detection can be abused to trick the game into believing a solid wall is ground beneath Mario's feet, allowing him to jump. Frame-precision is needed, hence the tool-assisted aspect of it.

The tasvideos.org page has more info in their wiki.

Slashdot Launches Re-Design

DeHackEd Broken CSS in FF2 (2254 comments)

I'm a firefox2 user (laugh it up, I'm not switching on this machine) with noscript. The CSS horribly broken, the sidebar follows me around cutting off content (as other people have said), there's a huge screenful of empty space on the homepage, content is fairly obviously in the wrong location and... oh god, click if you really want to see it. Turning off styles makes it slightly less painful.

And I just noticed the copyright on the bottom of the posting page here says (c) 201, Geeknet

Icons on my (computer) desktop:

DeHackEd Zero, and it stays that way. (384 comments)

I deleted nautilus (the Gnome program that manages those). Never liked it. Now my desktop is completely clean.

Even if I had them I wouldn't seem them very often anyway. There's always something open on my screen covering most/all of my screen area. It's better this way.

Browser Private Modes Not So Private After All

DeHackEd Don't forget about flash (198 comments)

Flash cookies, or even any temp files left behind by video playback. I've heard it happen. See if anything was left in your Temp directory matching "Flash*" and play it back as .flv or .mp4. Very incriminating evidence
