There are other things for signatures than just notaries. There is a "medalion signature guarantee" in which case certifying institution will be on the hook so to speak if they don't go the extra step to verify who is signing. They will usually ask for multiple ids, and will keep copies of them for records.

Most people just never have to deal with that, it is kind of a obscure service that few bank provide these days to the public:

Sure - Woz built a metronome - then realised it looked a bit like part of a bomb, and intentionally modified it to look like bomb, then hid it in a locker and purposely rigged it up to tick faster in the expectation that it'd be found.

That's a _lot_ further down the path of "intent to create a bomb hoax" than "building a clock".

(And personally, I'm of the opinion that putting a schoolkid in jail for what Woz did was ignorantly overreacting... Quite possibly because I was that same kind of schoolkid who'd make that same silly decision. Hell look at my Flickr photo's comment - I thought it would be hilarious to do that at 43 years old, it's just experience and perspective that stopped me building exactly what Woz made...)
Isn't this a rehash of the C10K problem[1] from a decade ago? That was pretty much resolved in favour of single-threading and asynchronous IO, with Nginx and Node.js replacing Apache and Ruby as the platforms that the cool kids use.

So, if threads are the way to go today, what has changed in the last 10 years to turn the conventional wisdom on it's head? 64-bit processors and servers with more memory? Hypervisors/containers? Are threads in Rust more practical than they are in C?

(BTW, these aren't rhetorical questions, genuinely interested.)

It's also possible to have policy that is intended to stifle, or harm a specific race. I mean Jim Crow laws were less than half a century ago.

When you expect problems from your interactions with someone ('frontal collision with popular opinions'), you tend to find them. This is the sort of belief that can be self-reinforcing, almost like a "self-fulfilling prophecy."

It's best to avoid things like speculation as to motives or intelligence of others. It only leads to mean words.
I took computer science at a high school in Texas (graduated in '08). We were taught everything from basic imperative programming to analysis of algorithms (and this was just a public school, not a magnet school).

I keep in touch with my high school CS teacher and that school now offers four years of CS education with multiple CS teachers. Your profile says you're in Round Rock, I graduated from Seven Lakes near Houston. My experience does not match yours.

There are some companies that sell things to IT people that use glacier natively. Veeam makes a very good backup product to backup VMs and uses Glacier natively. No need to use APIs you just select the VM you want to restore and it brings it down from your Glacier store. You have to remember that most IT people have no idea how to use an API, and aren't on Hacker News.
As in, each email requires a bruteforced hash that takes about half a second to calculate on a desktop CPU, before it will be accepted by the mail server?

That's actually the best idea for spam reduction I've heard so far (which is not really saying a lot). Half a second won't be noticed by a normal user, but it will be noticed by people sending thousands or millions of emails.

Sure Spammer will install large GPUs hashing rigs and still manage to send thousands of emails per second, but it would cost them a lot more than it does now.

One problem will be phones, a hash that takes about half a second on a desktop will take tens of seconds on lower end mobile phones, which is hardly unworkable but you could offload the calculations to a 3rd party server (with a large GPU based hashing rig) for say a fraction of a cent, especially if the email contents were encrypted by the phone before hashing.

And it could be introduced without breaking the email system. Initially the presence of a hash will just be used as an additional spam filtering signal, but as support grows over time you can make it harder and harder for emails without a hash to get through.

Like bitcoins, you would need a mechanism to increase the required work over time, though it could just be ad-hoc based on what mail server operators choose to accept.
I've used it a bit, and I have to say I agree.

Look Glacier is great and the prices are really good. But it isn't something an SMB wants to be using directly. Now a large enterprise who can dedicate engineers to this, sure, but an SMB really wants to be utilising Glacier by means of a third party service in my opinion.

I think it is wise to think of Glacier as cold storage. So if you need recoveries RIGHT NOW, well, it may not be for you. If you can wait 24 hours? Sure (and, yes, I realise you can recover faster than that, but between transfer times, and actually starting the transfer it can take a while).

Can you please get into the nitty gritty? Why is anyone using IEX if there is so much HFT on it?

Edit: http://blogs.wsj.com/moneybeat/2014/08/11/debate-over-high-f... Seems like there is some debate. IEX claims 17.7% which is still higher than I expected.

All they did with the high pricing was make it a prestige item, like Singapore's car licensing costs - they've made driving a car far more of a prestige thing.
Ask HN: What am I doing wrong or where is the Fail?
On Tuesday, I had what I thought was a decent interview. 1 manager type, 5 Devs. It lasted about an hour. This is response I got:

“The interview with Chad did not go well. He seems like a good guy but he is carrying some anger from past jobs / experiences and it came across in the interview. For example: we asked him how he handled a tough code/development problem in the past. The answer we were looking for is something along the lines of - I used one of the coding forums, I used Google, etc, etc. Chad's response was that his recent problems were not code related, but rather issues with the business side, company owners, etc.

I hope this feedback will help Chad in future interviews. His skill set seemed rather solid, but his attitude would not be a good fit for us.”

I'm confused, because one question killed the whole interview? Yes, I'm a good guy, with a dash of funny. (I honestly, work at being a good person, might have something to do with the number 12, only 10% will understand that little Easter egg.) My skill set is good especially in what they where looking for. I will admit that I am a little bitter about my previous job, as it was a start up and a lot wasted energy went into the process, but it surely wasn't enough to tilt an interview or maybe it was. I will be writing about that experience real soon.

It's frustrating, but I guess it could always be worse...

By the way, I'm still looking for work.

How do you know that they don't just flat out lie about these files being downloaded by your IP?

In Poland company bought out rights to one porn movie, then claimed to the police that that file was downloaded by random ip addresses (out of major providers pools) on torrent. Police ordered the companies to release home addresses of those ip users. Then the company slent email demanding settlment money. Some people paid. Now they are suing the company to get their money back. So many people police about this that they issue public statement that there was nothing criminal and they dropped the case.
Somewhat depressing that the earliest "heated discussion" I remember about this was nearly 20 years ago. The outcome of that discussion (with Alan Freier about the M:N and cooperative threading implemented in NSPR at that time) was "if only we could just make threads work". Seems like progress has been pretty slow toward that goal, although Go has picked up the pace recently.
Yes. That is a sad, sad paragraph. It reads like genuine ignorance on the part of the writer.
There is considerable magic of that kind, actually, because the build system has to be able to prevent insufficiently-entitled engineers from being able to back out the protected source code, while still allowing the program depending on the protected code to be built, linked, and debugged.
Why would they? App reviews are just user comments, they're not curated content - and trying to force the one to be the other would inevitably go down a weird rabbit hole. "I'm not allowed to tell you that I find this 'cheat on your spouse' app objectionable, but I can say that the screen transitions are crisp, and the text, while deplorable, was clearly legible on both my devices."
>Lawyers, for example, are trusted third parties that provide this sort of protection in certain cases.

"[Attorney-Client Privilege] It applies in all situations, though a lawyer may be required to testify regarding client communications under compulsion of law." [0] All that you do in that system is shift the risk from the client to the attorney. If the attorney is not willing to lay down their life for you then you're out of luck. How does one verify that an attorney will not give them up if compelled?

> We ought to spend some time thinking about them rather than simply accepting as dogma that anonymity is an unalloyed good, and that anyone who challenges this view ought to be downvoted into oblivion.

People raping children and spreading the depiction of those acts is bad, but if you want provable protection then you have to take the bad with the good. If the anonymity or pseudo-anonymity is not trustless then it should not be trusted in life or death scenarios.

I don't know enough about IEX to know whether the below is true. If IEX has this 'magic shoebox' mechanism in place, it might follow that they care about establishing a fair exchange in other ways too. There are hundreds of ways in which HFT firms profit from understanding the architecture of various exchanges. In some (many?) cases, HFT firms know more about the exchange architecture than the exchange does. The 'shoebox' addresses just one (mostly outdated) source of HFT competitive advantage.

Perhaps employees of IEX drink the koolaid because the exchange actively seeks to eliminate architectural areas of unfairness. The only thing publicized is the 'magic shoebox', but perhaps there are many more such features. Again, this is just conjecture.
More cores, perhaps? Though I don't know if that's actually true in a server context.

I think a lot of folks think of Network IO when they say Asynchronous IO. That's only half the story, unless you're just building proxies and caches you have to deal with Disk IO at some point in time. And, async disk IO is horrible in every OS / language.
It maybe isn't scalable, but that's part of the benefit. If you want to make a change to a widely-used API, it's going to be a lot of work, and it's not going to be a lot of work for the users of the API, it's going to be a lot of work for _you_ because _you_ are required to do it yourself. This prevents a lot of API churn unless the benefit is clear and sufficiently large.

If it was any other way you'd rapidly reach a useless equilibrium where random engineers were demanding that thousands of other engineers fulfill unfunded mandates for what might turn out to be negligible benefits.

Jack Ma: 'Making money is easy, spending it is hard'
I'm aware of the context. I'm also aware that it's difficult to prove.

I agree there's ample reason for suspicion, but suspicion is not the same as the certainty I see so many people leveling.

I've recently had a reminder of that. Not long ago, in Oakland, a black man was in a car crash on a highway. He was being pursued by police. Something happened, and police shot him. OPD does not have a great reputation, so when they claimed he had been attempting to hijack a car and advanced on police with a gun, they weren't really believed. Protests formed, claiming the man had been unarmed and fleeing police. OPD had killed another black man because they're racist!

It wasn't long before video and more information was released. The man had hijacked a car, crashed it, and was trying to hijack another when police caught up to him. He was armed, and had advanced on the police with a gun. The whole obviously false story was true.

Moral of the story: just because an event seems to fit a narrative doesn't make it so.

Here's your nitty-gritty:

If a participant places a large buy order into the IEX, this is going to affect the price of that asset, both at the IEX (obviously) and anywhere else it is listed, along with any correlated assets.

Now, the original participant will have bought its shares at the price it wanted at the IEX and be happy about it. However, market makers at other exchanges will not be aware of this upward price shock just yet. They will be blindly quoting sell offers at a price that had just been bought in bulk at the IEX. Whoever can receive the information out of the IEX 'magic shoebox' first and shoot that information over to the other exchanges will be able to make a profit. You can see that it doesn't matter how long the IEX delay is.

The original buyer will be the first to know of course, but they are unlikely to want to take on the risk of all available shares at that price at all exchanges. Thus, there will likely be some left for HFT to take.

You said "developed/deployed" as if it were the same thing. Even if you somehow checked in the giant flaw, bypassing all code review and automated testing, it's not like that would suddenly appear in production. Google isn't some PHP hack where you just copy a tarball to The Server. Binaries of even slightly important systems typically go through many stages of deployment, first into unimportant test systems, then usually very, very slowly into production with lots of instrumentation and of course, quick and easy methods of rolling back to the previous release.

No, if anything it is an understatement of how problematic this pledge is.

The only part that I don't quite understand is #6 where they talk about the "supervision of society".

"Supervision of society" is what the modern government of China has moved to as an quasi-alternative to traditional communist "Command and Control" planning[1].

It encompasses both the type of business regulation that is more familiar in the West (business licenses, safety regulations) along with comprehensive state surveillance of both financial/economic indicators as well as what many societies would consider "private speech".

Right...but the important function of IEX is that it protects the block order buyer or seller, and it seems to still be doing that, so it sounds like what they are doing is working.
Just my personal opinion but I think the mediocre hardware would be OK if it came with a bargain low price.
I don't think so. NYT is pointing out that dangerous language is buried in a bunch of innocuous items, which is totally true, i.e. keeping all data in China (5) and to "accept supervision of all parts of society" (6), which both sound pretty clear as to intent tbh.
What is "under-representation"? How do you measure it, and how do you determine when all "certain groups" (which are what, exactly?) are "represented" proportionately?

These are serious questions. How do we decide: what groups should be represented (what about ugly individuals? people with specific disabilities?), and when everything is all "fair"?

No, backwards: the C10k techniques are the solution to the problem "how do I achieve my performance and scaling goals given the characteristics of the OS, languages, tools available to me today?". The current thread (sic) is asking the question "if we can change the language, tools (perhaps the OS too), what's the best approach?".

And: I have to counterbalance the assertion that Node.js is in any way good for anything besides "I need to code in JS, but not in the browser". I'd rather use VAX assembler and the $QIO syscall, typing on a VT100.
