Comment: CoreOS uses systemd (Score 1) 201

You may be right, but I wonder if the author of the article is aware that one of the leading cloud friendly distros, CoreOS, uses systemd. If fact, systemd is an integral part of fleet:

With fleet, you can treat your CoreOS cluster as if it shared a single init system. It encourages users to write applications as small, ephemeral units that can easily migrate around a cluster of self-updating CoreOS machines.

RedHat's geard, which is part of OpenShift, also uses systemd.

It seems to me that the opposite is happening, cloud ready distros are choosing systemd.

I think you're missing the point. Mirix was trying to say that injection molding will always be cheaper, for mass production ($5 being roughly the cost of a mass-produced, injection-molded chair). 3D printing will never match the per-unit price of mass-producing items, but it *will* (and has already started to) make the production of small-run items and prototypes much, much cheaper.

If the key (the pad) is perfectly random, then there won't be any pattern. If the key was something like the first chapter of Moby Dick, and it's known that the key is an English-language text, and something is known about the contents, then you've got some patterns to work with, and it might be possible to retrieve the plaintext (and the key, simultaneously).

If the key is perfectly random, the plaintext won't be retrievable from the ciphertext, since for any candidate plaintext that you could construct, there would be a corresponding and equally-likely key paired with it. Trial and error can't decrypt a message encrypted via random one time pad.

ComputerWorld seems to be the source of the "1000-fold increase" quote. Then again, they also state that 512GB is "more than half a terabyte", so they're at least consistently inaccurate.

As for the temperature, the Fahrenheit scale is used on SanDisk's product page for the new card. Presumably, that's because Sandisk is an American company, and that page is marketing to a non-scientific audience. In the U.S., that means Fahrenheit would be used.

That's true, in the theoretical sense. Algorithms can be described in English or in mathematical notation. Runtime complexity of an algorithm can be calculated by hand. Most often, we want a way to also evaluate those algorithms, to take measurements on their behavior, and to understand them more intuitively. Computers are useful for that, but only if there's have a way to give them instructions. It follows that a student must be taught the rudiments of programming to have an automated method to explore the properties of algorithms.

This is analogous to the use of scientific instruments in astronomy. Everything can be done by hand (technically), but tools make things quicker and easier. They act as force multipliers to make more things practical to do in a shorter amount of time. For astronomy, that means that the astronomer doesn't need to be a million times closer to the thing they're observing in order to see it clearly. For computer science, it means that I don't need to evaluate a billion algorithmic steps by hand.

I find many of the things that people choose to *do* in a free society distasteful. That doesn't mean that I want to restrict rights or impose my will on others. I'd actually rather avoid that as often as possible. It's not my place to tell someone else what to do or think, if they're not actually hurting me. My reaction is purely emotional, and I don't like for my emotions to dictate my actions.

I don't expect respect from people that don't know me, but for something to be called a "dick move", it actually has to be an action. But go ahead and keep making the assumption that what I say on the Internet maps in a straightforward way to my actions in life. Seems to be par for the course.

Or that the company that funded the video's production wants some assurance that a subscriber won't just tee a rental into a capture program and distribute it without charge to the public.

That's OK. Some clever person will have already figured it out for me. I don't know if they strip HDCP-protection from video and capture the stream, read it out of memory while decoding, decrypt DVR video files or what, but I've no video that I've ever looked for was actually protected by restrictive streaming requirements.

If the executives of a production company feel assurance that their stream can't be ripped in one way or another, then they're living in a fool's paradise.

There are other scenarios where an SMS or MMS may be better. During a home invasion, when you don't want to expose your hiding place by speaking. In a situation where it would be useful to send a picture. In a location with weak signal, where a text transmission may get through even when you can't connect for a voice call. And then, you've got the cultural issues. A lot of people (especially the younger ones) barely use speech calls on their phones, any more, and a text may be the first thing that comes to mind when trying to get help.

A cell phone is a flexible device. I don't see a problem with enabling its use in whatever way we can, when it comes to helping someone in an emergency situation.

Lose your distaste.

I'm sure that there are things in the world that you find distasteful as well, and it would be just as effective if an anonymous internet poster said to"lose your distaste" for those things. It may happen through long exposure and desensitization, but it ain't gonna be purely by your say-so.

Photography isn't a crime. Neither is staring intensely at someone and refusing to stop if they're clearly uncomfortable or ask you to. That doesn't mean that it's not a dick move.

No meaning? Look up CVC3 security. Apple did nothing new here. It is all standard. It just works because the credit card companies have been building this stuff up for years and years. You don't have to know about the counter, it is there to prevent cloning.

What if you decrement? That is the whole point! You can't clone a transaction! Even if you get the CC number, the counter would prevent it from being used. This is a low level security measure that makes NFC payments more secure than magstripe. It is a good thing. I'm happen that Apple finally added NFC.

The biggest mistake you can make is to believe that you are working for someone else.
