I think the main reason they did not expose lower level semantics is that the wanted a drop in replacement for hdds. The second is liability: unfettered access ti arbitrary location erases (and writes) can let you kill (wear out) a flash device in a really short time.
SATA vs NVMe vs SCSI/SAS only matters at the lowest levels of the operating system's storage stack. All the filesystem code and almost all of the block layer can work with any of those transports using the same HDD-like abstractions. Switching to a more flash-friendly abstraction breaks compatibility throughout the storage stack and potentially also with assumptions made by userspace.
“Eutectic alloys are also notable because they often have the lowest melting point”. Isn’t the very definition of eutectic the mix proportion that has _the lowest_ melting point?
Not precisely. It’s the lowest _local_ melting point on the composition-temperature phase diagram. One material pairing can have multiple eutetic points.
Also, the fact that everything melts at the same temperature isn’t particularly important -it’s easy to add more heat. It’s really that everything freezes at the same temperature.
Optical computation will never become relevant at scale. There are fundamental reasons for this: first, particle size. A photon at usable wavelengths is extremely large, much larger of any modern electron based _devices_ This makes it imossible to scale to usable density. Second, optic-optic (as opposed to electro-optic) non linear effects are based on interaction with electrons, in particular with electron decay from an energy state to another which is tipically extremely slow.

How complex can it be? If you have a bare minimum background in basic physics and control theory, and a bicycle in your hands, the qualitative reasons for balance and stability will jump at you in under 10 minutes...
Please don't post unsubstantive dismissals of others' work to HN.
If you know more than the rest of us, it would be good to post an informative comment that teaches the reader something. If you don't want to do that, it's fine to post nothing.
If you feel that something is trivial and potentially wasting other people's time by means of wasting pixels, I think it's fine to speak up. (Explaining why something is trivial may not be that effective, in general).
I was clearly wrong in that many people disagreed and found this to be an interesting and nontrivial subject.
Ok, I guess I could have provided more info. Do this if you own a bicycle: hold it by the saddle perfectly straight, front of the bike forward. Make it lean on the left (no forward movement). Look at the handle, it steers left.
When you're moving this means that when you lean left there will be a torque, due to your circular path you'll be following, that will try to make the bike lean right.
Bend left -> torque to the right, bend right -> torque to the left. Here you have the basic ingredient for stability: the one torqueless angle is the bike going straight perfectly vertical wrt the ground, while any perturbation leads to a torque in the opposite direction.
I absolutely agree, all those negative comments sound like rants from grumpy old guys. I have worked in HPC distributed storage and the problems the CoreOS people are trying to solve is a valid and present one: deploying flexible distributed storage today is an absolute pain.
Plus all the arguments about local storage failure being hard are moot because this is a distributed solution and the hardship of local storage reliability can be abstracted away almost completely.
That's great news but: 900MBps != 5GB/3sec. Plus last time I checked (2 years ago) write power for flash was about 10W/GBps and growing over time. So I expect these speeds not to be sustainable for extended periods of time.
No it doesn't. They found evidence on his computer that strongly suggests there is child porn on the encrypted drive, there are witnesses that claim "John Doe" showed them child porn and he admitted to knowing the password initially, it was only later he claimed he forgot.
Prosecutors need sufficient evidence to obtain from a judge warrants, and in this case a decryption order, before they can hold you in contempt of court.
Of course, the evidence required for a warrant is still typically less than what is necessary to convict. The issue here is something to do with fifth amendment rights, which honestly I don't know a lot about because I'm Australian.
"All of the microbial sequencing data and health and lifestyle information that we collect are made public through the European Bioinformatics Institute, enabling researchers from all over the world to ask groundbreaking questions using the American Gut dataset."
Yes. They even provide the Jupyter notebooks that power all their analyses so you can re-process and re-analyze the data. I was looking into AGP recently because I had the idea that variance component estimation could be used to quantify how much gut bacteria composition matters, along the lines of GCTA for genes, and they were by far the most open and best dataset around.
Little known implies that if you ask 100 randomly selected people if they know if it exists, what it is and what it does, a small number, say less than 10 or so (little) will know.
Did you take your educated guess at that fraction?
Most concepts posted about on HN, and for that matter, discussed by the EFF, are "little-known." The inclusion of that description in the headline is obviously intended to make the reader believe that the committee is up to no good in secret, not that most people simply don't know of it.
Oh well -- the EFF knows that if they write for themselves, there'll be lower-brow comment-threads full of 'lol wtf bbq' and no one will take them seriously because they won't understand. Write accessibly, and well-read nitpickers of a HN-like brow alignment will pick apart their clickbait headlines. Damned if you do, damned if you don't.
I don't think that's what it means in this context.
I bet if you ask 100 random people, not 10 would know what Stripe is. Not 10 would know what Angular is. But would you ever describe either of those as "little known"?
I think in this situation it implies that even if you're in the domain you aren't aware... and on this it's not really the case right?
and the top of this thread is now a stupid meaningless
argument about a word in the title instead of talking about the issue. Well done. Can you guys take that rubbish to reddit or voat or somewhere crappy? I like reading HN, please don't make it a waste of my time.
and since I'm here now I'll throw out my opinion on the meat of the story.
I use Tor a lot and am not based in the US and am nor american. If America gives itself the legal ability to hack anyone, anywhere regardless of what they are doing then all american networks/nodes/people are open to hacking and posting publicly. That includes all private people, public people, everything from correspondence to baby monitor cameras. It calls for an open season against those countries whereby we air every single persons dirty laundry in as public a way as possible.
It is similar to europeans like UK, where certain people there think they can hack all people everywhere, legally, with complete immunity.
Excuse my parlance but fuck everything about that. That is a system balanced way too far in one direction.
but hey, that guy said 'little-known' about the Judicial Conference of the United States. That's what is important to americans...
Posted without Tor because I still live in a free country and am not afraid of speak up.
If the EFF was able to write posts that weren't full of gross hyperbole and flat out untruths then every comment thread about an EFF statement wouldn't require discussion about how the EFF is misleading people.
They know perfectly well what they are doing. They know it leads to people talking about the stuff they exaggerated rather than the actual issue. They know that it turns away reasonable people. They are gambling that they can whip up an ignorant mob as with SOPA. The difference there was that a bunch of high profile corporations and capitalists had a financial interest in that fight and were happy to fuel the outrage machine to get their way.
What are the untruths and what is misleading people? Keep in mind that not everybody who watxhes EFF is american, I never heard of that group before and I read most of the big tech sites daily since the late 90's.
Why would the EFF want to turn away reasonable people?
Here's the rub (for me). If what you say is correct then to my mind the EFF is doing you a favor. If people don't get at least a little riled up about this then it will go through like all the other rubbish being passed around the world and you will be left with the consequences.
The arrogance is absolutely astounding, on a level with 16th century britain. To think that you can do what you want, to whomever you want, wherever you want in a completely legal manner is disgustingly arrogant and will lead to the same problems as it always has throughout western history.
We have been here before. Technology changes but people (unfortunately) do not. The people pushing this kind of legislation will suffer the least, ordinary americans will take the brunt for them. That is your choice - is this move representative of you and if not - will you do anything to stop it?
edit: excuse my ignorance but this si actually about warrants through proper court mechanisms? I'm okay with proper warrant procedures through proper (ie. not FISA) court systems. I don't hold US courts highly compared to others but every country needs proper procedured.

Edit: it seems he got it back :)
