@Gilles as I said, Classic Theme Restorer will essentially restore that. the button has a Firefox icon instead of ≡ but otherwise I believe it's what you're looking for.
Small amounts of certain types of programming are reasonably within the scope of what a system administrator does.
Uncontroversially, writing a shell script to start a daemon, check if its running, and stop it is within scope (i.e., an init script). So is a shell scripting to automate system adm...
... finally, my answer to the C API question.
@Gilles @strugee @FaheemMitha I don't think you'll get notified that I added an answer to the Unix C API question, since you didn't ask the question. meta.unix.stackexchange.com/a/2967/977 is my answer.
I'd assume that if it were trivial to block them by IP, they'd already be blocked. Maybe it comes from a botnet, so tons of different IPs. Or tor (do we take anonymous edits from Tor? No idea)...
Ah, that'd explain why Google decided to ask me repeatedly if I was interested in it. No, Google, I'm not. You should know better. You're supposed to know everything.
@Braiam I think you crossed a few ideas in this sentence, I'd fix it, but I'm having a hard time untangling the mess: "You can't just dump some piece of information for more accurate that it may be, without spending any effort racking your brain thinking what means a tag/topic for Unix & Linux, this site."

hi and welcome to Stack Exchange! this question was downvoted because (since we're all volunteers) we expect people to show minimal effort before posting a question here, and you clearly have not. I advise you to read up on what, exactly, kexec is and then try again later. — strugee2 mins ago
at least I don't feel offended, I read the /about and instead of digging up a bit more information about the topic I decided to ask with a slate blank mindset
@strugee I'd have phrased it nicer (I'd reserve that for someone with a history of similar questions)... but I don't have any objections to that wording, either.
Yeah, let's replace one problem with another shall we? Do you really think the folks who run w3fools would try to fix it if it was a wiki? They may not have the resources to keep everything tip-top, but they don't have the resources to manage a wiki either.
if W3Schools refuses to change then sending something to them will do nothing. making a public statement will perhaps help convince them to fix things.
@Seth from their perspective, W3Schools is an active source of harm for the web. remember, W3Fools was created by people who are involved in the W3C and in browser engines. they wanted to do whatever they could to get people off W3Schools.
I don't care what their perspective was. Their tone did much more harm than good.
And trying to support that attitude is silly IMO. We all agree w3schools was not up to date, but the way they chose to point that out was inappropriate.
@strugee - well, I don't blame you for not wanting to discuss it. Those dwarves need attention. Probably one has taken a fey mood and barricaded his workshop demanding more and more materials for his masterpiece. I always let him starve though.
running your own server is as simple as allocating a pseudo terminal. not to mention exorbitant cpu time. every one of those little dwarves is a learning evolving thing and every turn means consistently reevaluating its ai.

I'm an awesome user myself but mostly because of my history with it. From what I hear i3 is probably where I'd land if I was just starting with tiling managers today.
@Rojo The buzz is generally that i3 has less weirdness that most. Tiling is a whole different paradigm than most folks are used to. Once you get used to it it's hard to go back though!
@Caleb You use it because it is more productive or because you have slow hardware / small screen?
@Caleb Yes. I think I might get used to it and love it. But I will miss a few things
Perhaps it would be best, given that I have 2 screens, to try to have i3 in one and something "standard" on the other, for the time being. But since I don't know how to do that, I'm sticking to i3 for now :P
I don't know how i3 handles this, but you can probably mix and match floating and tiling paradigms. I know AwesomeWM can do both and for a few programs (and/or virtual desktops) I have floating stuff setup.
I have a fast desktop (8 core, 32 gig RAM, 4 Gig video with a good chipset, 3 large HDMI monitors) and awesome makes managing that much space and speed effective. The ability to have multiple virtual desktops on each monitor with various arrangement with some windows being in more than one arrangement is indispenisble.
I also run it on a handful of Raspberry Pis and an old Pentium-90 laptop with 32 megs of RAM.
@Caleb Hehe, that makes sense. Mainly if you are a multitasker
I still don't know how/if to do some of those things in i3
(having the same window in multiple workspaces, saving arrangements...)
One little thing I'll miss that was productive is the following. I used to use Guake on gnome, which is a terminal that drops down half a screen instantly, on a key press (and is by default semi-transparent), and goes back up on that keypress
Furthermore, I need to find a good replacement for a gnome extension for todo.txt todo list
I do it with a modified version of this: awesome.naquadah.org/wiki/Drop-down_terminal (and yes it can overlay a semi-transparent drop down console over other full screen or tiled arrangements). I'd be shocked if there was NOT something similar for i3 out there.
@Caleb Thanks a lot. I honestly didn't have the time yet to google in depth; but I was slightly hopeless in anticipation. I'm very happy to know I was wrong :)
@Rojo Naw it's going to be possible to rig up, it just might take some tinkering the first time (which is kind of par for the course with tiling window managers). Figuring it out takes more time up front as it isn't designed to be "obvious" it's meant to be "out of your way" and flexible. But by flexible, pretty much anything you can imagine can be done if you care to set it up.
@Caleb Great. I guess I was under the impression that the low memory footprint came with a price, but if the price has nothing to do with productivity, perfect
@Rojo Actually it's surprisingly easy. But whether the properties are set via the window manager or the individual programs (some terminals like URXVT can set this as part of their internal preferences) you need a composite manager to actually render the output.
Check your distro and/or i3 guys for a recommendation, but compton is probably a good bet. Just install and run it and any window manager or apps that set the Xorg properties that tell a window to be transparent will start showing up.
@Rojo I feel you there. That's how I ended up being a Linux consultant. I was a draftsman, but was so vocal about how the software should work I ended up programming CAD software. Then I was so vocal about how the software development process should work I became a systems admin. Then I was so opinionated about infrastructure that my ISP gave up trying to please me and let me rebuild their network. Now I don't know what I am.
@Caleb question, is there something useful about hardlimit the network speed instead of just allowing the maximum speed allowed by the technology used?
@Braiam Ya. That's what QoS is all about. I've used tc a lot with Linux routers, but there are several systems out there. OpenBSD actually has some pretty nice QoS/firewall related stuff these days. The Linux stuff is kind of baffling to untangle although it works well once you get it all right.
Working with monit I need create an alert that get cpu usage of system users, so:
top -b -n 1 -u user1 | awk 'NR>7 { sum += $9; } END { print sum; }'
seems a good solution but I'm not sure about reliable because when I do above command, every time change (obviously) the value. So, I need an "e...
I need to monitor CPU usage by users of two servers' (Ubuntu and CentOS). For example:
user1 5%
user2 10%
...
Is there a tool similar to top or htop that can do that?
Yes and no. Absolutely the overall quality of service to each user AND the way it shares is much much better if you run each link at a touch under the hardware max. You cannot even do sane QoS filtering if you don't throttle back from your total enough to give your queues something to compute. But you're probable talking about something else.
In the case of giving your 1 MB vs. whatever the hardware could run at it's mostly a financial thing. They can either charge you for higher levels of service or sell to more customers without overloading the system.
ISP's usually oversell their own bandwidth. If they have 100 MB coming in, they sell 1MB to 1,000 (or even 10,000) customers. You never have everybody on at once so no customer ever sees their own speed go below 1 MB like they are paying for. But if you sold them all 10MB service (or let them run at whatever speed the line supported which would be even faster) they would quicky start seeing varied rates depending on how loaded up the network was that minute.
And the complaints would start piling in. Even if you sold a 1MB service level and let it go up to 5 when you had bandwidth to spare, your customers would all mutiny after they got used to having 5 during the day then only got 1 in the evenings.
@Rojo There are a lot of different models. Is there a project in specific you have in mind?
@Caleb No, just a general wondering. Any specific model would answer my doubt. Perhaps free software doesn't mean you can redistribute it to anyone other than your friends and neighbours?
Or it mostly only makes sense for software that you continuosly develop?
@Rojo There are lots of different licences, some allow redistribution some don't. Some projects are written because the author needed them for their own use, then gives it away to others. Some were written collaboratively by a group that all had similar needs and all pitched in to make it happen. Some projects rely on donations to support ongoing work even though they give it out for free whether you donate or not.
I hate the upsteam/downstream miss-match on aDSL. I know why it's there but it's a decision in the best interest of other parties, not MINE (as somebody who uploads nearly as much as downloads).
@Rojo Stinker. I didn't have that when I was in charge of an ISP. Of course that was a lot of years ago. Now I have a lot more on some datacenter computers, but not at home.
@Caleb The ISP chose me as a test subject for their fiber, and then they probably stopped investing for a while, so I kept it for a couple of years until they decided to start selling it
@derobert lo and behold, that price has attached another ridiculously expensive home line service. If you want bare internet the price spikes to 170 USD range
@Caleb I thought it was due to greater crosstalk at the telco side? Seeems unlikely there is no reason, as even on business lines can't buy symmetric. Or even reasonable upload rates.
(Now, given, there are market segmentation reasons too, but the point of those is to drive you to higher-cost business lines. But the asymmetry exists even there.)
I don't want to delete or add, just want to modify one rule. Is there such a command or do I have to resort to Delete and Add ?
