computer··on Linux: Difference between /dev/console , /dev/tty and /dev/tty0
With systemd you simply do:

  journalctl -f
where the f stands for follow.
computer··on Show HN: Control your local uTorrent, Bittorrent client with Angular.js
You're allowed to download video & music, not upload it. Bittorrent also uploads data.
computer··on Coming Soon to Hacker News: Pending Comments
As I understand it, it would lack responses to pending comments, since nobody can respond to a comment before it's endorsed.
computer··on HipHop, a new Windows/Mac app that offers free music streaming
Any reason to not open-source it? I doubt you can build a startup out of something that's probably against the Youtube ToS, so not much to lose.
computer··on HipHop, a new Windows/Mac app that offers free music streaming
Just an executable? No source code? No information on who you are? I think you'll have a hard time getting people to trust you.
computer··on Show HN: Logarithmic Flappy 2048
I suspect you know this, but either way: you should initialize your arrays in R to the proper length-- dynamically growing them within a for-loop as you do with values, func and results in optimxWrapper is extremely slow in R, as it creates a new array every loop, copying the old one.
computer··on Earth dodged a massive magnetic eruption from Sun that could have wreaked havoc
Well, hypothetically: unplug everything on that side of the planet right before it hits, especially the main power lines.
computer··on Push for Australians' web browsing histories to be stored
Are you suggesting to commit computer fraud in an attempt to break government security systems, thereby giving terrorists and pedophiles free roam?
computer··on Popcorn-app
Sure. But the app seems to be focused on streaming very popular torrents, which means that generally all pieces will be available enough.

Also, all Popcorntime clients want the same blocks first, meaning they will both need and seed the first blocks more. So they do not cause an imbalance, as long as there are always some peers that have the full movie.

computer··on Popcorn-app
Right. The actual app supports torrents for movies that have non-free licenses as well.
computer··on How the NSA Plans to Infect “Millions” of Computers with Malware
So the only thing the NSA has to do is hack/convince/rendition/break-into-house a single person who holds a package signing key, and then they can MITM your pacman updater and have you as well.

And there's enough people with such a key to choose from: https://www.archlinux.org/master-keys/.

(I run Arch as well, but I have no such illusions of security.)

computer··on InstantClick 3.0 Released
Unfortunately, links might change state. Links on some sites will delete records, and a browser has no way of knowing which.

Also, it generates a much larger server load. Look up FasterFox and the related controversy.

computer··on Critical crypto bug leaves Linux, hundreds of apps open to eavesdropping
Are all programs dynamically linked with GnuTLS, or are there packages that have to be recompiled separately? (On Debian/Arch)
computer··on GnuTLS certificate verification vulnerability announced (CVE-2014-0092)
For the Apple code we did not have the full commit history. Do we know the history of this bug yet?

Edit: See https://www.gitorious.org/gnutls/gnutls/blame/6aa26f78150ccb...

computer··on Beets – Command-line music manager and auto-tagger
Try Clementine, it has both a local library and integration of Google Music, Spotify, Grooveshark, etc.
computer··on What Are the Dangers of Using an Untrusted USB Drive?
They're missing the possibility that the drive might decide to simulate being an USB hub at some point. It can then be both a USB storage drive and a simulated keyboard, and use the second to install something from the first.

Doesn't it mean we can do CA-free authenticated HTTPS? That would make it useful for me.
computer··on Does Causation Imply Correlation?
Here's a harder question: is it ever possible to deduce causation based on data alone? We all know that correlation does not imply causation, but is there anything that does?

If not: prove it. And if yes, under what conditions exactly?

computer··on GCHQ intercepted webcam images of millions of Yahoo users worldwide
Let me take a stab at creative government-speak:

No, this is also metadata. They are only taking a screenshot every few minutes, with as aim to get a clear picture of the face of the person operating the computer. Just like an email header contains a From-address in the content that's metadata, a webcam session contains the same metadata in the form of these screenshots of people's faces.

They're not collecting the data, i.e. the moving webcam video + voice. They have no idea what's being said. Just metadata.

computer··on New message from Mt. Gox
It actually made me laugh out loud. The statement makes it seem like MtGox was all fine and dandy until media started to talk about its shutdown. And now they say:

> We will be closely monitoring the situation and will react accordingly.

As if they're just sitting back, staring at their screen, waiting to see what will happen. Passively.

So, was this plus automatic updates over SSL one of the ways the NSA could access "any iOS device"?

Any chance the pdf file was up early and they simply guessed the URL? This announcement was named 20140220-Announcement.pdf (https://www.mtgox.com/img/pdf/20140220-Announcement.pdf) while the previous one was 20140217-Announcement.pdf (https://www.mtgox.com/img/pdf/20140217-Announcement.pdf).

Try it the next few days.

Nearlyfreespeech is explicitly not for anonymous hosting. They are just very unlikely to take anything down without a court order forcing them to do so.
computer··on Nootropics Survey Results And Analysis
First a warning, because I've seen many misconceptions: Modafinil is not a sleep replacement. Especially not long-term. Do not use it that way. Its anti-sleep property is that it suppresses many parts of the urge to sleep. It does not provide any of the effects sleep provides.

--

Well, I've always had issues with sleep: I have an 25 hour circadian rythm, so before modafinil I often just let it run and wake up an hour later every day. I thought modafinil might be something useful to help me experiment with my sleep. Note that I did not get a doctor's receipt, so I imported the drug myself. (I'm not in the US; it's not a felony where I am.)

You say "in comparison"-- I must say that I do not have much to compare it to. The only other substance of this kind that I feel an effect of is caffeine, and it's on a completely different level, in all ways.

Side-effects I noticed were mostly dry/chapped lips, reduced appetite and diarrhea-- the last of which seems not to be very common.

In terms of its nootropic effects, I'm normally very bad at focusing on stuff for long periods of time, and for some periods it helped me focus for long times on tedious things. Or it helped me focus on cleaning the house really well, reading the internet thoroughly and avoiding what I had to get done. But if I used it and spent a night studying, I would remember the material studied very well. This concentration effect was also the quickest to fade after longer use.

The main effect is its anti-sleep property is that it suppresses many parts of the urge to sleep. It does not provide any of the effects sleep provides.

Right now I don't use it, because I am not working on anything that would benefit from it, and the side effects are not worth it to me right now. Also, melatonin has helped me with my sleep rythm issues for some time, so I don't need it for that.

I did not notice any addictive effects whatsoever. There's no high you get from it, nor a low after you stop, perhaps besides sleeping a bit longer for a few days.

computer··on Nootropics Survey Results And Analysis
There's a theory that there's a group of people that has a genetic mutation that makes modafinil not work for them. That might be the case for you?
computer··on Nootropics Survey Results And Analysis
I have a fair bit of experience with modafinil/adronafinil, so if anyone has any questions, feel free to ask. I'm not recommending trying them without docter's prescription, of course.

It helped me greatly to stay up longer, to sleep less, and to concentrate better. However, those effects get much weaker over time: the sleep effects for me were less clear after 1-2 months, the concentration after weeks. Side effects can be nasty though, including limited appetite and gastrointestinal discomfort.

For the rest of the list: I've also tried various -racetam's, and they did nothing for me. Creatine, vitamin D don't have nootropic effects for me (but I still take them for other reasons). Caffeine is meh. Haven't tried the rest of the list.

Any chance you'll open source the products?

You missed the word "invisibly"-- they can join/watch without showing up in the Cryptocat client as being present.
computer··on Google’s IPv6 Stats Pass 3% Less Than 5 Months After Passing 2%
So, do all your (startup's) domains have AAAA records yet, and servers IPv6? I just enabled IPv6 on my stuff, which took much less work than expected.
computer··on I've made an open source flappy bird clone
fwiw: I discovered a strategy that works for me: don't look at the bird, but look to the top right of it. I got 21 and 20 in a row, after getting a high score of just 5 before switching to this strategy.
