Hey, thanks a lot! Didn't expect such a great reply. I was still a bit fuzzy on a couple points, if you don't mind. I'm visiting another country and haven't found reliable wifi yet, hence slow reply time.

I think I get the scale invariant theory concept from a mathematical perspective, but I don't see why this would be the case: "Because you've got this considerable mixing of the two states, often "zooming in" is the same as, say, adjusting the proportion of liquid to gas"

Regarding random matrices, my understanding now is that given a random matrix of sufficient size, under a suitable definition of "random," if we look at the eigenvalue density function it's always going to be (roughly?) the same--we at least know it will be semi-circular. Further, there exist physical systems that can be modeled by random matrices; and there's a mapping between eigenvalues of the matrix and certain physical characteristics of the system. So, knowing the density function is always the same for these random matrices, we can assume certain shared characteristics of any systems that can be modeled by a random matrix.

In random matrices and phase transitions we would like to know how certain macroscopic parameters will behave, given some data like a matrix, or state of a phase transition. But, in both cases our starting data contains a lot of essentially irrelevant data that these theories prescribe a method for filtering out, since it assures us that knowledge of the symmetries involved are all that will matter.

Am I close? :)
Questions for Tom:

1.) How are you handling auth? Are you using a home grown solution or using OpenID Connect + OAuth 2.0?

2.) Is the JWT behind the firewall using a pre-shared key?

3.) What does the public token look like and how does the API Gateway perform auth? Does the token passed into the API Gateway contain only a user id? And does the API Gateway have to perform a database query to populate the full user object?

side note: Thanks for writing the article.
Been there, done that. AWS re:Boot in September 2014 showed us how good it was to invest in Ansible roles for all parts of our infrastructure. Still, a lot of hassle for Ops Team, especially that it was done during DevOps Days Warsaw ;-) AWS also said '10%' then, but for us it was 81 out of ~300 instances.

What is sad is that we learn about it from Hacker News and not from AWS, even when we have premium support and our own account manager. :/

Let's see how many of us did their homework after previous "xen update", and how much "10%" is now ;-)
Michael, interesting point of view. It seems that you are well versed into these things. What's your specific experience, and would you mind sharing some specific stories (without naming names)?
Basically you've made an unsubstantiated claim to write it off

What, exactly, is "unsubstantiated"? Do you doubt how Canadian Parliament works? Do you doubt that he's a member of the opposition? Do you doubt that all of his claims are vague to the point of meaninglessness?

It is throwing some fetid meat on the table and saying "make a meal". There is zero possibility of it leading to valid conversation. It is just another partisan post that would invariably lead to those tiring comments by people saying the trite "Sorry for Stephen Harper" nonsense.
they probably are operating at a pretty
high percentage, so gradually idling 10%
of their host hardware would probably
put a pinch on availability

If they can withstand the loss of one of out of three availability zones, they must have at least 33% spare capacity in each AZ, ready for new instances to start to take up the slack from the lost AZ.

Even if they have more availability zones than the three they show to users, I would hope they would have more than 10% spare capacity!

The problem is that if you are part of an activist group that has "members" who are extreme enough to commit criminal acts, law enforcement does not discriminate. Once a couple of members commit criminal acts, the entire group is guilty by association. We see this with race and religion, why would it be any difference with ideologies?

For example, if you go to enough Animal Rights protests, I've heard that you start to get a "profile" in law enforcement databases (at least in the US). Just look at how "AgGag" laws are passed specifically to "protect" specific industries from activists that want to film what goes on behind closed doors (and bring it to light).

As another example, look at the way that law enforcement in Canada dealt with the G20 summit.
But they used to.

Show HN: flash file security scanner
I would love to get some comments and suggestions, to see if people would actually use this and what functionality they want.

This has been sitting around for a while now and I have not got myself to finish it yet.
As you will be able to tell, this is still rough and not polished (more or less a prototype).

http://thorly.batr.am/

There are many commonly used flash files that are known to be vulnerable and are used all over the place regardless.
Thorly aims to give you some idea about which files to avoid.

Simply input a URL or upload a flash file and it will check for common security problems (for example XSS).
At the moment the user only gets information about whether the file is assumed to be vulnerable.

This will only be a short test run and I will probably take it down after a few hours (to scared to let it run on its own).
If you will be programming professionally (or for significant amounts of time) learning either of emacs or vim is absolutely worth the effort.

You will be very glad you did.
Vim can be blazingly fast and maddeningly slow — it all depends on the plugins you have activated.

I once tried to use VLC to stream an MP4 stream captured by some kind of 3rd party driver so that others could use their VLCs to connect to it and watch what's on air. However, as soon as I begin streaming, it always hung on me (normal playback of the same MP4 captured stream is fine). Were there any improvements in streaming part of VLC? Is it even supposed to work?:)

Thanks, top notch player, I use it exclusively on all my PCs.

C-51 has nothing to do with that, though. It doesn't tell CSIS to start investigating environmental groups.

C-51 gives law enforcement and intelligence some slightly more modern tools. For instance, they can demand that "terroristic" material is removed from the internet (where jurisdiction applies), which is a right that they already have for child pornography and hate material, with the agreement of a judge and the minister of justice. If they become aware of a subject, they can ask that the subject's ISPs capture data pending a warrant (versus waiting for the process of the warrant and perhaps miss things).

And so on. Remarkably few who comment on C-51 have any idea what it entails, or the scope changes it offers. But they ply, ironically, exactly the sort of rhetoric of fear that the right wing plies about terrorism -- somehow having an advance ability to request data capture == All lefties are going to be locked up.
>It is just another partisan post that would invariably lead to those tiring comments by people saying the trite "Sorry for Stephen Harper" nonsense.

Not a single person here has brought up Stephen Harper, except you. It sounds like you're itching for a fight.

The point of the "op-ed" (which is, by definition, an opinion piece) is to raise awareness that our public representatives have issues with the legislation, and hopefully move the debate into the public sphere. I don't see anything wrong with that.

Now, whether this deserves to have made it onto the front page of HN, that's debatable.

At the very least, they wouldn't have the overwhelming advantage when negotiating peering terms with content and carrier networks. Eyeball (broadband) networks currently have far too much power, and is the reason why they make huge profits while pretty much every primarily carrier network loses money. The cost of Internet connectivity is dependent on the cost of cable in the ground, and the cost of equipment. For both, carrier networks have to make larger (and thus riskier) capital outlays and pay a premium to operate at a larger scale. Meanwhile, the broadband networks received billions of public funds on the condition they'd ensure access in rural areas and provide a minimum level of service, both of which they haven't done yet kept the money.
Lenovo's Promise for a Cleaner, Safer PC
DSL providers are forced to let resellers (also known as competitors) use their networks. Cable providers get to capture the speed increases for themselves.

This is why people were afraid of the "let one company build the network, but everyone else gets to compete on it" plans. It might make all the networks look like the DSL networks.

And this meme that Internet speeds are staying flat is just plain wrong. Akamai's state of the internet report consistently shows average speeds increasing year-over-year in nearly every state in the US. ("Vermont was the only state across the
whole country to see a year-over-year decline in its average
connection speed—the cause of this decline has been discussed
in prior issues of the report.") For peak speeds, only Vermont and Oklahoma saw year-over-year losses.
> A lot of that may have to do with all the infomercials that used .biz and .info.

Maybe true, but things like .academy just reek of potential scammers/fly-by-night operations that could not qualify for a real .edu.

Things like .lawyer also feel more inclined towards "ambulance chasers" rather than real law offices with money to get the .com they wanted.
"see your ranking on Github" is similar to "see the number of friends you have on Facebook" or "look at your word usage on Hacker News". It's clearly being used to refer to the platform, not the site.

Besides, it has just a box for entering your username, which then scrapes data and presents it--hardly a phishing site.

YesGraph (YC W15) Raises $1M to Build a Better Referral System for Mobile Apps
It depends on your definition of "bad." The Ma Bell monopoly certainly constrained your ability to even hook your own equipment to their wiring for many years and resulted in an uncompetitive market in terms of pricing. Even intra-state long distance was very expensive by today's standards. (Though some of that was a function of the technology economics as well.) On the other hand, it just worked. US telephone service was extremely reliable.

>(That's not to say that you should stay in an unfulfilling job forever - just that you should make hay while the sun is shining).

I agree. I'm almost 30 myself and have been living quite extravagantly as you say. I'm hoping to spend my 30s building sufficient wealth that by my early 40s I'll have a passive income sufficient enough to let me essentially retire to somewhere nice where I can spend my time on self-actualization.

It's interesting that more of this kind of content keeps coming up on HN, it seems that many of us are tiring of the "rat race". I hope I treat the next decade in the right manner so that I'm not looking at HN submissions on self-actualization or breaking the mold in 10 years and regretting not having done things.

>Both working on a farm and programming are surprisingly creative professions.

For all the shit rural culture gets around here, I'm usually impressed by the ingenuity of its homegrown hacker-like culture. I sometimes get frustrated with my overly automated urban life. Apartment/condo living with a low maintenance car/appliances/technology and a worklife where I'm shuttled to and from via public transportation doesn't leave a lot of room for fun little hacks or impromptu solutions. The room that's left is often trivial gimmicks like tying something to tasker or messing around with whatever platform or language is hot right now.

Then I bought a fixer-upper house. As frustrating as this can be sometimes, there's just a great rewarding feeling of learning new things, fixing things, adding value to your home, etc. Real life hacking that isn't servos or screens is surprisingly rewarding. A small farm must be this x100.

Making bread is something for which cookbooks and recipes compilations are ill suited. Bread is invariably about ingredients and technique.The flour is different, the water is different, the yeast is different, the ovens produce different transfers of energy, etc etc.

So this is about corrections, adjustments, and tacit knowledge about what you can do to "push" (really 'nudge') the output in a calibrated way.

The author is correct that iteration is essential to learning in this contex. But iteration is not "failure", but simply "mediocrity" with adjustment.

Referring to mediocrity as 'failure' lacks requisite precision, although maybe it sounds cool.

As many others, I often get frustrated when working through different problems. But I find taking a break and doing 'outdoor activities' such as backpacking and rock climbing gives my mentality a break. Afterwards, when I go back to tackling my problem, I feel refreshed.

Taking breaks to 'get back in touch with nature' while doing something so technically involved tremendously helps my workflow.
