If it's about passing coding tests, my advice is to ask money for that (like a wage of 42$/h). As you are skilled, you don't need to prove it (you already know you are). It's their problem if they don't trust themselves at evaluating people. Best companies I've worked for didn't ask me to pass tests.

Customers I work with use to say "I want work with you (and not with someone else)" after talking a bit with me. Make that situation happened and you will feel better and earn more money.
Yup.

Pretty sure an i7-8700 is only about 40-50% faster than my nearly 6 year old i7-3770.

I keep thinking "My system is 6 years old...it's time to upgrade" but I just can't justify it. I'm still running DDR3 (Granted, 32 GB of it), so I'd need to do the CPU/mobo/RAM trifecta.

It seems that it is more sensible to say that entanglement is locality. The notion of two points being close to each other appears to be a course-grained approximation of high amounts of entanglement in the vacuum. If you divide the space along a boundary and break the entanglement between regions on both sides, the effect is to increase the distance between them. So perhaps it is better to think of gravity, locality and dynamical spacetime, as the "hydrodynamics of entanglement"

The makers of OxyContin have been losing lawsuits [0, 1] for aggressively and misleadingly marketing (saying that it wasn't addictive) the drug for pain management leading to the levels of opioid addiction that we see in cities around North America. I think pharma, particularly Purdue, deserves the lion's share of the blame in this.

Possibly, I don't believe radar has the necessary resolution compared to photogrammetry and lidar at the distance self driving requires.

Someone with self-driving experience, please correct me.
It's worth noting that none of this is available on 'AWS' China.
I don't see how arbitrary AWS instances are in any way going to go 'obsolete'. They have been around for a decade and are becoming more and more normative.

Second, the underlying financial principle is that with visibility comes lower volatility comes lower cost - that's some very basic financial logic that's at play here.

Yes, of course the contract implies a degree of vendor lock-in, but this is inherent in the nature underlying operational costs.

"RIs are a lock in." - of course. And if you don't want to be locked in, then you're going to have to pay a lot more: AWS, GCC it doesn't matter, it's the same financial reality everywhere.

Markets are just a tool. Entirely unregulated markets exhibit some undesirable properties. Society, through government, has every right to aim to diminish the ill effects of these undesired properties. But it also behooves society to be careful in how it regulates, in order to avoid diminishing the usefulness of this tool. It's a balance. This is not as sexy or simple in principle as either extreme, but it's the right answer.

This is one of those cases where regulation makes sense. I think regulations aimed at improving information symmetry are some of the best. They are fairly low impact; maybe they stomp on an arbitrage opportunity, but they don't limit the solution space nearly as much as regulations that simply proscribe what you can and can't do, for instance.

Basically: the "hard libertarians and anarcho-capitalists" are just wrong. But if they were to rebut with a take down of state controlled economies, I would definitely agree with them about that. The trick is to strike a good balance.
I'm not a EE but four transistors for a D-FF is hard to beat. Z-80 other contemporaries also used dual phase clocks. Obviously the downsides outweighed the transistor overhead eventually.

There was a "modern" instantiation of this by Intrinsity (got acquired by Apple) whose "FAST-14" [1] dynamic logic used a four-phase clock. That was pretty cool and they had some (for the time) insanely fast products. I wonder if that logic style would have been feasible in the 6502's time frame.

They dont. The power levels are less than 1% of military radars. Plus mass production. They are talking 10,000$ per unit, which isnt all that bad for cell equipment that can aim itself.

Military radars are for detecting quiet targets, not cellphones wanting internet. It is total apples and oranges in terms of energy levels.

10% of the population is hardly "almost zero". I'd also question the premise that it's "what we want". On one hand I'm not sure the drug wars (money into the cartels, families broken up by incarceration, the cycle of drugs leading to violence) was worth it. On the other hand I don't like the idea of the government telling people what they can and can't do to themselves. Drugs are largely a victimless crime.

> I am teaching a C++ class and am struggling with the quality of the code my students are producing. Their programs output the correct answer, yet the style is really lacking.

I remember trying to help fellow students with their C and C++ assignments back in undergrad, and reading some of their code I got the distinct feeling that most of it was “random-walked” code. Like they tried writing things that looked like C, making random, iterative changes until it compiled. Then once it compiled, made random, iterative changes until the output approached what the expected output would be. Sometimes the functionality ended up right, but with bizarre stuff like: unused variables all over the place, variables assigned then reassigned without using the first value, uses of pointer indirection that look like the student kept adding or removing asterisks until it didn’t crash, elaborate class hierarchies that went unused, etc. It’s like the Infinite Monkeys Eventually Producing Shakespeare thing but with programming assignments.

/me Looks at probably the only two devices from an entire production run from a startup in 2013 that're still getting updated.

I built the private ARCH pacman repo for these, and the GPG signed OTA software update mechanism running on the devices. I'm _still_ proud of it.

When the startup failed the hosting bills didn't get paid and the domains became "assets for sale" by the liquidator. Even though I'm still updating/securing things for my devices, I have no way to share those updates to the customers we sold em to...

You don't think that MITM is a kind of impersonation attack? DHE is a mechanism for agreeing on a secret; it does nothing to authenticate the station you're agreeing on that secret with.

Think of what happens in TLS interception; DHE still takes place with the intercepting device, it's PKI which tells you who you're agreeing with.

I think I just realized something about golang as I was walking down the hall. This is something which confuses many people in a way which many respond to with unwarranted emotion, since they are unable to make this connection.

Since Go uses Duck Typing, having certain methods is effectively a Type Annotation for a given type implementing an Interface. Many programmers, failing to realize this, become outraged at "boilerplate." It is a design trade-off forcing the programmer to specify all cases when implementing an interface, in much the same way that golang's exception handling eschews tools that let you create clever catch-alls and requires you to specify everything. It's just the "no magic" tradeoff.
It attempts to. Whether or not it succeeds depends on whether the highly questionable SAE protocol actually works — see the other comments here.

Also, what's "best", documentation that greatly explains a horrible, unintuitive interface of a program or one that hardly needs to exist because the use of the program is so intuitive, you don't need documentation? Greater effort was spent in the former, but you understand the program better in the latter.

I have a Bachelor's degree in CS. Nobody will hire me because I don't have experience.

Funny thing is, before I got my degree, they were happy enough with my experience but wouldn't hire me because I didn't have a degree. Even had the same interviewer tell me one of those things on either side of my graduation.

"Get a degree and we'd love to hire you for your experience!"
"Oh, sorry, you're qualified but don't have any experience."

It's like my degree reset me to zero.

I maintain a version of your "complete list of credentials" professionally - and every time I've left a job I've supplied that list saying: "Here are the company-related credentials to which I've had access. This list is best-effort and may not be complete. Please respond acknowledging I've advised you to change these and any other credentials I've ever had access to."

I know a guy who moved to New Zealand from Hungary, with several years experience in broadcast TV. He thought New Zealand was going to be a new start, and got a job at a regional TV station working with a friend of mine.

After about a year of working for that place, he got very angry with it and quit because they were cheap beyond what you can imagine. He ended up doing a lot of overtime to make up for software and hardware problems. A few years ago moved to Auckland to work for a production firm up there, thinking it would be a better job.

Rumor has it that he gave up and went back to Hungary.

We're going to see some amount of beamsteering (and/or MIMO) on the handset side too. But only 3-10 elements--nowhere near the 1000s on an AESA.
Thanks for writing back, sorry if my tone wasn't great before.

> optimization was no good because the schedules it gave were "too tight".

This matches fairly well with my experience -- getting a good objective function can be half the battle. A lot of people don't know what they want well enough to tell you.

> Mostly people in business just do NOT want anything technical

Well, in competitive markets it'll eventually be "do or die", and for common enough problems it doesn't need to be done in-house. I agree that businesses are (typically) very conservative about this sort of thing, but if there's value to be had by wringing efficiencies out of operations, Uber and Amazon will do it.
I think this is a really illustrative example of how business strategy can influence decision-making.

"Paying AWS's profit margin" assumes you can get access to their cost structure. You can't. In order to get AWS's cost structure, you need to (a) be buying servers by the truckload to get volume discounts, (b) have a scaled labor force for physically moving, racking, and installing all of this that's insured, directed, and managed to high rates of utilization (want to pay devs to rack servers?), (c) hire expensive network engineers whose cost is fully amortized across AWS's massive installed base, (d) fully amortize all the software engineering required to control all of this, etc.

So the more realistic option for a typical company is, do I (a) try to do this myself, with the time delay, risk, and cost profile of a nonspecialist provider, or (b) pay Amazon, which will cost about the same as (a), but be better in every other way, EVEN THOUGH amazon's superior cost structure lets them make a decent profit off of that decision?

(b) is clearly the right choice. It costs you nothing more, Amazon gets to make profit, and everyone is better off. Point being, you are forced to go with Amazon because they have structural advantages you don't, which gives them access to a better cost structure that you can't replicate.
> The user interfaces for the Lisa and the Macintosh made almost all the right choices right from the beginning

No, they did not. Off the top of my head:

- No cursor keys. You had to reach for the mouse every time you wanted to move the cursor. Rectified later, yes, but not the right choice from the beginning.

- Menus across the top of the screen, inherited from Xerox Alto whose portrait format monitor made vertical space most plentiful, did not make so much sense on the Macintosh landscape monitor, still less so on today's letterbox monitors.

- One-button mouse leading to a workaround where to perform the most common operation of running a program or opening a file required clicking twice in rapid succession. Windows fixed the first problem immediately, but the second problem only years later.

- Copy-pasted text bringing attributes from the source document where it should take them from the destination document. This problem still has not been fixed to this day.

Like other artifacts, the Lisa and Macintosh had their good points and their bad points. Let's not let appreciation of one blind us to the other.
Im worried about the health of the company if it can't afford a slightly more expensive keyboard that will last years and make me more productive.

If that is a big ticket item I would wonder if they are in serious trouble or it's just a shitty place to work for. A managers response to a request like that should be "here's the corporate card" or "submit the receipt for reimbursement"
No, it does not. Generally speaking, Google "converges" a layer up (BigTable, Spanner, Colossus). There is no layer like LevelDB that is common to all of these.
Well, I'll give him another 20 minutes. But that's it!
Trying to circumvent a repressive regime's laws is not a great design spec for the internet. Why not make Tor mandatory for all TLS 1.4 connections?

Either they'll use traffic analysis to find out where you're going anyway or they'll just ban all HTTPS connections. Not that they need to as Russia is fine with just blocking whole IP ranges, making SNI irrelevant.
>There are so many other costs to running your own datacenter besides the servers and the space, which Amazon gets to amortize over all their customers, but you have to bear 100% on your own.

Yes, but those costs may be low (or zero) for you, but Amazon has to architect at a level much higher than that. For example, I have researchers with data that has zero backup/DR requirements. This is 10s of TB of data, but if they lost it all due to a fire or a catastrophic system crash, they would just shrug, order a new storage array from the insurance money, and request new copies of the data from the research labs at other institutions that also have it. Amazon doesn't offer any storage products at that reliability level, and the ones that are even close have significant data access latencies or file transfer costs to run analysis over a significant chunk of the data.

So, they buy a basic NAS, stuff if with 12T drives, and pay $0.19/Gig for it. That's one time, not monthly, and at only 50% utilization. Assuming S3 Reduced Redundancy is $0.02/Gig/mo (it's actually a little more, but we're being generous), they start saving money in month 10 not counting the data transfer or compute costs associated with processing that data either locally or in the cloud.
As much as I hate all the block chain hype, I could see smart contacts facilitating this kind of coordination.

I guess there would still be a discoverability problem, not to mention the very significant risk of putting your money into a scam.
A year or two ago Y Combinator startups would be given around $1M in Azure credits, should they move to Azure. GitLab.com at the time moved over to Azure, with the goal being to reduce costs before we consumed those credits. I think we consumed all of it in a matter of months. Once you're stuck with a hosting provider (Azure or not), it's difficult to move away from it.
I think quantum mechanics really is different. Consider a fundamental aspect of the quantum world, familiar to anybody reading Scott Aaronson's blog: the 2-norm.

People are familiar with how probability works in the classical world. For a given event with several different possible outcomes, like flipping a coin, the probability of those outcomes sums to 1 (here, 1/2 + 1/2 = 1).

In the quantum world, probability doesn't work like that. Rather, the sum of the absolute value of the probability squared equals one. A quantum coin flip has probability (actually called amplitude) 1/sqrt(2) for heads and 1/sqrt(2) for tails. |1/sqrt(2)|^2 + |1/sqrt(2)|^2 = 1.

This has huge implications. It means probabilities can be negative, since |-1/sqrt(2)|^2 + |-1/sqrt(2)|^2 = 1 (actually it goes further - the probabilities can be complex numbers!). It means negative probabilities can interfere and cancel out positive probabilities. And a whole bunch of other wild stuff. All of quantum mechanics (or so Scott claims) follows from this.

I submit that a world where something as basic as the probabilities of all outcomes summing to 1 not holding is a world so alien that attempts to explain it in terms of our own experience will only end in confusion.

KMS is a hardware security module, kind of like the secure enclave on an iPhone. The private key doesn't leave the hardware, your process requests that KMS should encrypt or decrypt something (which is probably another disposable key used for your session to the a DB or whatever, like in a browser TLS session). All of AWS's core services are neatly integrated with KMS: EBS, EFS, RDS, DynamoDB, etc.

I'd trust the AWS datacenter security and processes over your average big-corp datacenter any day, having seen quite a few.
