So V(x) = exp(-pi(x)) and you use HMC to explore those potential energy level sets? But what happens when you change coordinates and get a different density, pi(x), a different potential energy, V(x), and hence different level sets? And why does the gradient help as it points transverse to the level sets and not along them which you would need to move in the right direction?

Maybe the momenta fixes that somehow? So you just add any IID gaussian variables to the target? You need special variables? Even so, why IID gaussians?

The problem with the "hockey puck" intuition is that it is incredibly shallow and obfuscates the underlying principles that really make the method work. Unfortunately the false intuition also motivates bad tuning strategies and method extensions which have real practical consequences.

Radford's review was really, really important but it was written when we really didn't know what was going on at a foundational level. The linked paper has the benefit of the last five years of research where we've figured those foundations out and consequently can identify the principled important to robust use of the method in practice.
Yeah, same here on US-WEST-2. Unable to use the S3 Console, but I can still upload/get content via the API it seems.

I guess their bizarre thinking is something along the lines of: "unless we have proof that noone can access the service, we won't change the indicator from green to yellow.

Seriously: I don't understand why you guys stay with AWS.
I didn't get that at all from the OP. His comment I'm fairly certain is of the "why the heck are we centralizing the web to 2 or 3 infrastructure companies" for what amounts to a minor amount of convenience.

We've seen this story play out in other industries and it never works out well for average people. It's been astounding for me to watch the pace of this centralizing and who is helping it along.

The tldr; point is that a single service provider should not have the amount of control Amazon does over the Internet. At least that's my take.

I know my opinion on this wildly differs from the HN crowd and SV "decision makers" these days - what is so curious to me is that this is a complete 180 from that same demographic even 10 years ago.
The dashboard doesn't load, nor does content using the generic S3 url [1], but we're in us-west-2 and it works fine if you use the region specific URL [2]. In practice this means our site on S3/Cloudfront is unaffected.

> Twitter's modern-day utility seems very low outside of news/sports/politics

What's the evidence for this claim? In academia, Twitter is super important, much more than Facebook or any other social platform. Academics are addicted to Twitter and I think you could charge them, e.g., for tweets longer than 140 characters.
Automation: less jobs, Government (at least in Europe/Cdn) say more people we need to import more people to fill the jobs... but millions of jobs will disappear over the next 10 yrs.
1. Let users charge for more rapid access to tweets and share revenue (eg. instant tweet access versus delayed access).

2. Let users pay to DM certain accounts.

3. Mesh-networked solution.

4. Launch 'labs' version as sandbox for developers and users to experiment with (eg. encrypted tweeting, blockchain embedded messaging, proxied messages, etc.)

5. Twitter comms OS embedded on hardware.
>businesses actually care quite a lot if their data leaks.

How are you coming to that conclusion? Companies may say they take security seriously and they want to avoid becoming the next Sony or Home Depot, but how many actually allocate resources accordingly? It's much more efficient to just issue a press release and offer to pay for credit monitoring services that virtually nobody will actually use.
GitLab really needs to provide a way to force HTTPS for domains that have it set up. I have to manually link with `https://` everywhere.

Sendgrid, Twilio, Quora is also down. Is this related to S3. Entire world depends on AWS
Slightly related, FYI all of the package downloads for Gitlab are timing out with a 504 error from Cloudfront ("Cloudfront is having difficulty accessing S3". The registry is also showing an error.

I'm trying to downgrade to an older version because our install is not working but can't get the DEB unfortunately.
I think Twitter is already pretty great. My suggestions are below:

- Twitter is a platform, open it up to allow any clients first class access.

- Stop political censorship immediately. It's fine to prevent scams and bot-nets, but do not stifle political speech.

- Lower burn rate. Cancel all of the product-oriented projects that are expensive, simply focus on building the infrastructure to make Twitter's platform as inexpensive as possible to maintain. I'd estimate 10% of Twitter's employees are actually needed.

- Be very cautious about ads. Do not compare yourself to Facebook for ad revenue generation. This is a long-term decision that will require adequate funding to undertake.

Ask HN: Why is Markdown so difficult to work with?
I find it's inconsistent across services at best, and a complete pain at worst.

Github is one of the few places that render it beautifully. There are a few services that do this, but they never work with each other. They all decided to add their own niche things to it, completely breaking compatibility.

Also, has anyone ever tried to export markdown to a more portable format? If you're extremely lucky, your PDF will have only a few rendering faults and your HTML, nah allow talking about the HTML.

I mean it's a really elegant thing in itself, I just wish it'd play well outside of Github's walled garden.

Has anyone else come across any of these problems? How did you solve them?

Yup. Some of our machines in us-east-1e dropped out of the load balancers.
I have in the middle of thoughts of moving out of AWS and having a dedicated provider as our billing has increased a lot with the scale. The only thing which was holding me was the uptime confidence. Now I feel it's not a bad idea.

You're right; I missed that. IMHO it should be much bigger, but I'm not sure there's a good way to raise awareness and start change.
I don't think there can be a satisfactory proposition of "accountability". We have an Oligarchic system which again, systematically undermines the rights of users. Software which is made primarily for short term profit, will undervalue privacy, because it does not sell. Things are centralized because with the current technology that's how they scale, and are easier to control, and convenient. And also because data about you is important, that's the real treasure.

De-centralization is what will give power back to users. Ofcourse I don't want every user configuring their own synchronization solution instead of using Dropbox, and Drive. But running your own server , with modular services like these (sync, backup, email etc), should be like installing apps on your phone.

Twitter's money issues can be solved by adsensing popluar / celebrity accounts.
Just give them a lot more intellectual freedom to do "the right thing" (instead of having to implement political compromises) and give them the authority to be really allowed to do so

That's exactly the one thing that working in the public service CAN'T provide you. If you screw up, you and everyone in the chain of responsibility right up to the people who directly report to your ministry's cabinet member have their necks on the line; public service employees typically enjoy very posh pensions and no one is looking to lose that by getting sacked.

I think we incentivize public service employees to do the safe thing rather than the right thing when those two things are not the same. Losing a public service pension is a terrible cost for failure, and I don't think we equivalently reward the success-side of risk for these people.

It would be interesting to know what government could accomplish if the public service gave compensation that was more in line with the private sector.

No, I was having issues with too much "magic" in Python libraries. I'm continuing to use Go for my new company.

In particular, running SQLAlchemy was a nightmare (see a reddit comment I made about it here [1]). I also wanted a more parallel language - I was tired of having to use queues to do parallel tasks. Go's static typing made everything easier, from auto-generating Swagger definitions to having usable code documentation via Godoc. Most of our runtime errors while using Python were due to type mismatches that could have been caught by a compiler.

I'm unfamiliar with Python 3.6 static checking. I'll have to look into it.

For the algorithmic scheduling - our algorithms in Julia predate the existence of a web app. We had customers using the Julia-based algorithm using the protocol "spreadsheets over email". The website came later, and we ended up switching the algorithms from Julia to Python after the web-app launch [2].

Mass outage like this is exactly one of the things we are looking to avoid by building a decentralized storage grid with Sia.

Sia are immune to situations like this because data is stored redundantly across dozens of servers around the world that are all running on different, unique configurations. Furthermore, there's no single central point of control on the Sia network.

Sia is still under heavy development, but it's future featureset and specifications should be able to fully replace the S3 service (including CDN capabilities).

Twitter also has incredible utility in terms of the InfoSec and Quant communities. All the latest papers and exploits are posted regularly, something that exists nowhere else. It also extends across borders, I follow numerous Chinese, Italian, and Middle Eastern hackers who post code and associating write-ups regularly.

The same goes for stock traders, the network offers incredible insights.
I'm academic. I'm not addicted to twitter, nor is anyone of my coworkers.
Shame we pay a bazillion dollars for it. Anyway, curious to know how you've thought about mitigating something like this? I worry if it happens to us govcloud users we obviously have much fewer options for redundancy.

And when that political speech threatens violence or is intended to foment violence against a person or people? 'Cause I'm not saying you're conflating the two, but a whole lot of people for whom this is an axe they grind really kind of constantly do.
IIRC the Console is mostly hosted out of US-EAST-1. Direct API calls to other S3 regions are likely to work, but it's not surprising the Console's having trouble.

I've been getting sporadic "Bad Gateway" errors on HN for the past half hour or so, not apparently associated with any one feature (such as profile pages). My suspicion is that it's unrelated to anything happening at AWS (HN doesn't have any AWS dependencies, does it?), though maybe everyone checking HN to see what the status is has increased load.
Yeah, bad morning. I started by trying to pull a Docker image. When I couldn't, I tried to push some stuff to S3. Now of course I'm checking HN. :p
I think perhaps the worst thing about Addepar is the way it sells itself to prospective (inevitably young) employees: that's it's on a mission to "fix finance." While there are some operational inefficiencies to be alleviated in the wealth management performance reporting space, the savings from which might at some point be passed along to asset owners, the actual result of Addepar's work, at least in the short term, is much less grandiose. I would characterize Addepar's effects as enabling wealth managers to continue to capture more of this value as you point out, while also assuring tax-efficient inter-generational wealth transfer.

This is perhaps a cynical and short-sighted view of Addepar (and I've been told as much by Addepar's management), but based on my experience in the investment management industry, I feel it's more true than false.
But wait. Isn't S3 "the cloud". Everyone promised the cloud would never go down, ever. It has infinite uptime and reliability.

Your talking about the difference between immediate mode vs retained mode, immediate mode being the "self contained render" method. This is nice and clean up to a point in complexity, and then the advantages of retained mode (or "manually mutating existing UI widgets to match the data every time it changes") outweigh the disadvantages, namely the management of the UI/data interface.
Azure is also down. Related?
Markdown was intended to be simple enough that everybody could roll their own code to translate to their "real" markup language of choice. Everyone did, but because markdown was a hack in the first place, the quality of implementations is pretty inconsistent. (Which is fine, because rolling your own markdown -> html translator is easy -- much easier than writing your own html -> anything translator -- and well within the reach of even beginner programmers.)

I avoid markdown because I don't like markup in general (and because I think styling of text is rarely useful), but if I need to work with it, I will whip something up to do the translation. A couple lines of sed is sufficient for handling whatever tiny subset of markdown is actually present.

> You don't buy a developer kit in mass intending to resell as an end product

Beaglebone black-like system boards are used for both development & production. I almost shipped a system like this personally. With the BBB, you can get slightly modified versions, in bulk, and with enough availability to satisfy purchasing. Even if you couldn't, the SoC on the BBB can be bought from TI. I imagine there are similar things for more modern, powerful SoCs. Many companies like isolating the complicated timing sensitive board design (as needed for NAND and off chip memory) from the rest of their design, and don't necessarily have the skills in house to do that type of layout. Pre-made boards like the BBB provide a lower cost option than a completely custom board.

With the RPis, you can't even buy the SoC. I'm not aware of anyone you can buy slightly modified (ie: unneeded components pulled) boards from in bulk.
I don't think they intentionally kept the checkmarks there. They probably just didn't update it as quickly as developers made a post on Hacker News (not surprising, they were probably investigating).

Thanks for sharing. I overheard someone on my team say that a production user is having problems with our service. The team checked AWS status, but only took notice of the green checkmarks.

Through some dumb luck (and desire to procrastinate a bit), I opened HN and, subsequently, the AWS status page and actually read the US-EAST-1 notification.

I don't know who you are, your age, background, occupation or where you live. Your view of reality is distorted to a significant degree. I am not saying you don't have a point here and there but things are not as dark and sinister as you seem to think they are.

Again, without having an understanding of your frame of reference it is hard to know where to go with what you said. Please don't take this as a personal attack. That is and was not the intent. I simply told you that what you are describing does not align with reality to a degree that is not-trivial.

Depending on your frame of reference an exploration of these ideas and their potential realignment could be a matter of a short conversation and a few links or hours chatting in person at a nice coffee shop.

I can put it this way (these are just examples):

Someone suffering from deep depression sees the world through a very different lens than someone who isn't depressed. A person who has success in life sees the world through very different eyes when compared to someone at the opposite end of the scale. Someone who enjoys a great family life views a reality not available to a person who's family life is nonexistent or tragically complicated.

I am not saying you fit any of the above scenarios. I am simply using them to demonstrate that one's frame of reference matters, a lot. Your portrayal of reality is very dark and negative. I urge you to consider that this might not be in alignment with how things are in reality.

That said, a perfect image does not exist. We are all influenced by our frames of reference to one degree or another. Nobody can claim absolute alignment with reality. However, the extremes are clearly not aligned with reality. Your view of what's around you seems to be very dark.
