know this firsthand. Had a job interviewer tell me that I was too old for IT work and show me the door because he wanted to read/follow my Twitter account, and I told him that I didn't have one.
"Over 40" is a protected class. This is no different legally than an interviewer telling you he doesn't hire blacks. If you didn't just make this up, it's worth suing them.
No, really, integer multiples of Planck mass. That's why it's an interesting prediction. The "all current particles are 0, more or less" bit is typical useless String Theory handwaving, but the discovery of a particle of about 1 (or n) Planck mass would be something. We still haven't built a successful dark matter detector, so the possibility is still real.
I can't make much sense of your post, and the linked article is a bit confusing as well. But if the claim is that the 2 cores from an m1.large are about what you'd expect from 2009, I can totally believe that - the m1 instance is pretty old. I'd expect them to be sub-2-GHz Xeon cores. Xeon is usually damn slow compared to the consumer cores from the same year, and it's not sensible to compare Xeon performance to consumer performance (or, at least, it's Intel's brain damage, not Amazon's).
From the docs, m4 is 2.4 GHz Haswell, and m3 is Ivy Bridge - they don't say the frequency so probably pretty low.
As far as cache, I don't know what hypervisor Amazon uses. I know VMware (which I'm sure they don't use) protects the CPU cache as long as you don't oversubscribe cores. "World switching" a core, as they call it, is the most expensive operation you can do in a hypervisor, so any hypervisor worth a damn will try to avoid that.
Measured in units of Plank mass, damn near: 7.7 x 10^-20. We don't know very precisely what the rest mass of quarks are, but the proton mass is about 1% from matter, as 99% of a proton's mass is binding energy. And we don't have any theory explaining why the rest mass of quarks is what it is - so it's possible we'll discover it's much lower, and there's some other sort of binding energy involved at a lower level.
Right, but they clearly promise you a number of cores. The easy assumption is that the cores aren't oversubscribed, and none of the docs suggest they're oversubscribed, except the docs for T2 (seems like it must be). Can't tell for sure, of course, unless someone can find something definitive from Amazon.
As I understand it, String Theory has one fundamental (and very odd) premise: that all particle masses are integer multiples of the Planck mass, with all known particles having a rest mass of 0, plus a bit of rounding error (OK, it all sounds fishy to me, so maybe I don't quite have that right). Anyhow, the discovery of particles with about 1 Planck Mass (obviously not point particles) would be an experimental triumph. And who knows what dark matter is - maybe there's a surprise waiting.
But other than that exceedingly far-fetched idea, I don't see any way string theory won't be abandoned at this point.
You're joking, but that is actually what a "Warm Earth" (i.e., not an ice age) looks like: no year-round ice anywhere. It doesn't get much warmer at the equator, but it gets a lot warmer at the poles.
It's odd how much Azure seems to struggle to keep up with AWS. MS has no shortage of cash, and at the very least they could offer "MS SQL instances in the cloud" as cheaply as they needed to go get people locked in, It's not like NoSQL and message queues are rocket science these days, and the AWS versions have fairly minimal feature sets.
In the old days MS was all about lock-in, and while you never wanted to touch v1.0 of anything from MS, by the time 2.0 came out they were usually ahead of the pack in terms of feature checklist (quality not so much). I guess they've lost that spirit.
Google spent so long just offering a limited set a quirky services in the cloud. It seems like they're smart enough to stomp the competition: it always baffled my why they didn't. (They certainly know how to operate at scale as good as anyone.)
That's a good link. My real complaint about AWS is what's mentioned at the end:
It also feels like a lot of services are stuck at version 1.0, lacking that polish and continual improvement
This is what annoys me. SQS is a good 1.0 version of message queues, but the features are the just above the minimum you could possibly call a message queue. DynamoDB is a good 1.0 version of a NoSQL DB, just above the minimum you could possibly call a NoSQL DB.
These services are years old, but look like what most software does at version 1.1 or so: minimal features, no glaring bugs, but nothing great either.
I can't say anything about EC2 CPU performance, as I've never benchmarked that myself, but aren't they just (mostly older) Xeons? The way the T2 instance is described makes it sound like the cores are oversubscribed, but I haven't heard that about the other instances.
In any case, unless you're CPU-bound, it doesn't matter. I'm more concerned about price for the memory I need. For compute-intensive jobs, EC2 Spot is cheap if you're really fault tolerant.
But you also hear things on vinyl that gets left out on digital media because the sampling rate isn't high enough.
This is not only wrong, but provably wrong. That's the nice thing about math: actual proofs. After you've listened to a record a few times, you've degraded the audio quality through wear. Perhaps you like that sound better? Many people like the distortion of tube amps better.
Also, most prominently used digital audio formats are lossy, which means some of the data gets lost as part of the compression process
True enough. Low bitrate MP3s annoy me to no end, but they're still better than cassette tape.
But there is no better listening experience than vinyl with a good turntable and high-end speakers.
You forgot directional cables. Don't hook em up backwards: you need your cables to be danceable.
Well, at least vinyl still does something that even CDs can't
Make hipsters happy? It has no audio advantage, to be sure.
Big fancy magtape can kick the crap out of a CD,
Make audiophiles happy? Make your cables danceable?
The only limitation of CDs (if you include CD-Rs etc) is that they only contain enough information to match perfect human hearing, so you might want more bits for the mastering process, where some information loss is inevitable. But for consumer use, just playing the music, CDs are right.
The only example that makes sense is a tube amp, which distorts sound in a way many people find pleasing.
Bah, all that's useless without proper power conditioning, including a perfect synthesized sine wave, plus you have to replace all the electrical outlets in your house with hospital plugs to avoid connection noise. And even then you get aground loop unless you cross-wire the power inputs to put live current across the device chassis!
Of course it goes without saying that you have only the best hand-laid pure copper power cords, with Egyptian porcelain stand-offs with vibration damping for the power cord (never confuse your stand-offs!), otherwise you won't perfectly capture those fast transients and your/dev/null will still sound digital.
Yay, another american dork who just sits at home all the time instead of travelling. Frankly thats in the best interest of the world. You fuckers just sit home and continue being the ignorant joke of the first world.
I live 4100 km from where I lived 10 years ago - all in America. How far from where you were born do you live today? If you think "traveling" a few hundred km for summer vacation makes you worldly, I think I know who's the ignorant joke of the world.
At first I was going to flame you a bit for saying that by purchasing a ticket I'm waiving my rights to not be unreasonably searched. But I'm really just tired of the whole police state thing. I just won't fly commercial. It won't change anything - there are too few people who are willing to be inconvenienced in order to preserve our rights, so Police State wins, I lose.
I'm really tired of this crap.
At the very least we can recognize that this is a police state!
When airport security checkpoints were run as part of the airline business (and were every bit as effective as the TSA without the loss of dignity), this was an inconvenience, but not a constitutional issue. Now you're searched by government employees without probable cause. "Waiving" constitutional rights is a bit of self-serving government nonsense that no one should fall for.
It's just as bad at the courthouse. I'm legally compelled to enter the building by my jury summons. I get search by police without probable cause. No where in the Constitution does it say "unless we're scared". The government is supposed to be scared of the people. But we've fallen as a nation, and the people are now scared of the government.
Who owns the means of production? That's your owning class. The idea that it will be "everyone" seems to be a lie told by totalitarian dictatorships, to judge by history, but you never know. More than half of Americans own stock, and that's a new thing in the world.
No system is ever perfectly fair and free of corruption. Who does the system favor? That's the powerful people in that society. The system favors the powerful because that's the definition of powerful.
How does one outcompete the powerful in a system that favors the powerful? One doesn't.
That's the only wrong answer. We don't have a system that's entirely corrupt. It's entirely possible to succeed without being born into the right family - people do it all the time, in fact. Degree of success is a different question, but for example anyone with a professional income can invest enough to become independently wealthy in America, over 20 years or so. That's not bad.
If conditions don't improve soon for a lot of people, the system is going to
Responsibility for improving one's situation goes first to oneself, not "the system". There are certainly areas where we're failing hard, such as providing job training to get people out of unskilled work without a huge financial burden, but that's very different from "no opportunity".
Entry-level jobs of all sorts are suffering, and will continue to fade due to automation. Skilled jobs are a bit different. Still, we really need something to fill the social role of entry-level jobs for teens, and raising the minimum wage really hurts that. I expect a huge rise in skilled, "personal touch" service jobs, but that would be especially hard for teens to get into. It's hard to find a good model elsewhere, too, as youth unemployment is really bad throughout most of Europe.
I'm hoping that, whatever new jobs arise to fill the unending demand of humans for "more", we have some sort of apprenticeship program. There will certainly be new kinds of jobs for skilled adults, just as there has been after every wave of automation, but that doesn't answer teens and the unskilled.
Many listeners considered that to be in poor taste. Elon Musk was originally from South Africa, and half the people SpaceX employs are not from the USA. People from many countries contributed to this.
If the US won the World Cup, we'd have the same chant. Wouldn't matter if none of the players were born here.
Service jobs aren't going away soon. Jobs where the personal touch matters aren't going away (but then, those jobs require a bit of creativity). The skilled trades aren't going away soon. Retail jobs may dwindle, but slowly, over lots of time.
There's very little manufacturing left in the US to lose. It's the "paper pusher" jobs that are currently seeing the hardest decline: not manual labor in the classic sense (that's mostly a done deal, aside from agricultural stuff), but nearly-mindless labor nonetheless. Entry-level jobs are also on the decline, which is IMO the worst problem we face on this front. That fast-food job you get as a teenager is an important step in life.
It's easy if you don't expose yourself to advertising. That's far harder with kids.
I don't watch TV in the ways that come with ads, I don't listen to radio with ads (I listen to public radio, but the kind that plays music, not the kind that's mostly NPR and discussions, which are their own form of ads), I run adblock on my browser. I do see the occasional billboard, I guess.
