> The comment about C is absurd

You missed the point entirely. When Unix was conceived, it would not be written in assembly language as was usually the case back in the days. C was seen as terribly slow, its functions were costly. The vision behind that choice was that performance was not as important as clarity of design and maintainability.

> The single process is sort of was done for dependant triggering of events between different event types to be done.

I know that. Using a monolithic architecture makes it easier to manage dependencies. It is not the only solution to that problem though, and I would have preferred another one, more modular. Since I'm not in a position where I can design my own init subsystem, I use systemd, but I can't help noticing this "dependent triggering" doesn't work too well yet. No magic wand will solve such a complex problem, and being unable to easily isolate faulty parts makes it in fact harder to solve issues.

> The Gphoto thing is not what you would call a core part of the system but is for your camera. I dont know what you expect it to look like, i dont see a problem.

Hmmm... Ok, let's repeat. Instead of gphoto2://[usb:008,044]/store_00010001, I want something along the lines of /media/user/Camera/. This is straightforward. This is something I can use in scripts (instead of godawful hacks like parsing dmesg to grab these device numbers). Instead, we have this annoyance, a false abstraction, yet another telling symptom of what is wrong with "modern" Linux.

- Use text whenever possible
- Performance is not paramount, so use C
- And do one thing at a time but do it well - connect small specialized tools to build complex applications
- Documentation, while terse, should cover all features
- The filesystem is a simple tree starting with /

Let's see what modern Linux does:

- Lots of binary stuff everywhere, where text would do
- You'll boot up faster with systemd, oooh yeah baby, totally rad!
- Oooh, and it's more integrated, one single process does everything!
- Look for processes with stranges names running on your machine, then try to find any documentation on them
- gphoto2://[usb:008,044]/store_00010001

The last one makes me angry. It's VMS all over again: is anyone here old enough to remember host::disk$1:[directory]file.ext;version? I can't find another way of accessing my phone data. I can't, for the life of me, mount it the way I would mount another volume.

Guys like Poettering couldn't care less. They have a vision, for sure, and they have good ideas sometimes. But there are really two issues here: a good idea is not sufficient when you engineer a system, and their vision is not Unix. To hell with simplicity, to hell with consistency.

Comment: JScript (Score 1) 386

No IDE here, but if all what you want is discover new territories, you'll just need an editor. Apart from PowerShell, there is another decent scripting language on Windows, which is JScript. That's a Javascript implementation allowing to access system resources through "ActiveXObjects". Example:

var fso = new ActiveXObject ("Scripting.FileSystemObject");

Have a look at MSDN for reference about this object and others, then browse it, and various blogs, while happily writing your scripts in whatever editor is present on your machine. By the way, they will run on any Windows system, even XP. The drawback is that interfacing to DLLs is often impossible when it hasn't been provided by MS.

Then, you might want to explore Javascript as a functional language - a usable Lisp in my opinion...

News sites usually answer on port 80, or 443, you know. 82 is highly unusual, so much that my corporate proxy won't let me connect. Who are these guys, whose site is on 82? Are they serious? I don't know, and couldn't read TFA, but this port does ring a bell in the "amateur news site" section.

See, they called Kader Arif a "Chief" when he's only the "rapporteur". From Techdirt on this subject, 'A rapporteur is a person "appointed by a deliberative body to investigate an issue."', far from a "Chief".

The main problem I see with the current economic system is that finance becomes more and more decorrelated from production and consumption of actual goods, be they manufactured products, or services. Well, it shouldn't, otherwise crises happen, and they did happen - two in the 2000's - and they will happen again if nothing is done to fix the mess. (I believe nothing will be done, and we will pay dearly for this.) That Bitcoin thing tries to solve unessential problems, mostly ideological, while making early adopters rich. Should it really gain momentum, however, I see nothing in it that would alleviate the risk of a future financial crisis. On the contrary.

UUCP had a command called cu (call up) which is what you need. From "apt-cache show cu" on Debian/Ubuntu:

The cu command is used to call up another system and act as a dial in terminal. It can also do simple file transfers with no error checking. cu is part of the UUCP source but has been split into its own package because it can be useful even if you do not do uucp.

Storm Worm Botnet "Cracked Wide Open" 301

Posted by timothy
from the after-honeynets-let's-try-bugzappers dept.
Heise Security reports that a 'team of researchers from Bonn University and RWTH Aachen University have analysed the notorious Storm Worm botnet, and concluded it certainly isn't as invulnerable as it once seemed. Quite the reverse, for in theory it can be rapidly eliminated using software developed and at least partially disclosed by Georg Wicherski, Tillmann Werner, Felix Leder and Mark Schlösser. However it seems in practice the elimination process would fall foul of the law.'

Comment: Another model (Score 1) 194

by jzu (#26072461) Attached to: Why a Music Tax Is a Bad Idea
I agree a music tax is a bad idea, but not for these reasons (TFA is more exhaustive though). Reward marketplace failure? But the music market is rigged. Bureaucracy? I don't think its inefficiency could surpass the majors' operations. However, a music tax would be unfair to those who don't listen to music. And how would one determine each artist's share?

Another flat rate music distribution model (this one being voluntary) might be this one, where music files belong to the customer whose ID tags them.

First, flat rate is convenient. Flat rate is one of the reasons why IP took over - bye bye, X.25.

Then, trust the users. Even if some of them remove the ID3 tags. Even if many of them do. Piracy is part of the music ecosystem anyway. Give them ownership, give them responsibility.

Finally, you have to count the beans - how many downloads for which files from which artists. That implies centralization though a hub. There could be many distributors (think Google or your.national.isp or whoever), who would compete for the same basic service, and add additional services on top of that.

But that's sci-fi right now.

Submitted by Ana_scape
Ana_scape (666) writes "Anascape, a texas based company, sued Nintendo for violating a patent on controllers. Instead of paying the $21 Million bond, Nintendo has decided to take all the controllers off the shelves. [...] As of July 23rd, no more Gamecube or Wii Classic controllers will be sold in the US. Nintendo, however, is not giving up. They plan on appealing the decision in a U.S. Court of Appeals for the Federal Circuit, which would put the ban on hold for the time being."

+ - Is YouTube killing music?

Submitted by

niceone writes "Recently YouTube seems to have started applying extreme compression to the audio of uploaded clips. This is the type of compressions used by radio stations to make everything louder, but in this case applied extremely badly. In quiet passages, breathing and shuffling become overpoweringly loud. A gently plucked guitar chord becomes a distorted thud. Listen to an example here. And here's what it could sound like — still not perfect, but a whole lot better. The fixed version is thanks to a workaround proposed by Sopranoguitar — the idea is to turn down the audio and mix in a high frequency sine wave (I used 19kHz). The sine wave fools YouTube's compressor into thinking that the file is at a uniform level (and does not need the volume changing at all) but is filtered out by the encoding process (so, no need to worry about deafening any dogs)."

According to all the latest reports, there was no truth in any of the earlier reports.
