It boggles my mind that they spent so much. CGI Federal got almost 300 million. The company I work for has an IT budget not much smaller. We employ over 1,000 people around the world in IT alone.

They must've had an army of people working on crap apparently. I'm sure they higher ups padded their wallets and walked away happy whether it worked or not. The first mistake was not finding a department with big budget experience.

Very true. Why do we need to have so many divisions, when we're all more or less wanting to make the same thing?

AWS US East is experiencing high error rates on several services
The services CloudWatch, SES, SNS, SQS, SWS, AutoScale, Cloud Formation, Directory Service, Key Mgmt and Lambda experience very high error rates for about 3 hours now.

Dynamo DB is throttling API access and seems to be having issues with the management of meta data.
Just to clarify: the cryptocurrency idea mentioned here is still state-backed; the prime advantages of a digital currency are in rapid transaction and in giving the state Bank more direct control over the money in circulation.

At present, the bank can choose not print more money (leading to deflation), or print money to slowly increase the amount of money in circulation (leading to controlled inflation, reducing the value of money in private wallets and encouraging spending behavior).

Digital currency will allow the state to simply dirrctly reduce the value of money (negative interest) across all private wallets to encourage spending behavior.

It is a very interesting approach that I think challenges our intuitions about currency, and will take some time to get used to.

I'm from the Bay, but I lived in LA (for a little bit) and SD (for longer) in my college years, with post-college being back in the Bay. While LA seemed to be all about bars/clubs, SD was more chill with bondfires and house parties.

There was an image, growing up, of BBQs and Potlucks as things "older people" (or at least families) do, but as I'm into my 30s, they are things I find myself doing with my friends. I'd be happy to know more people are doing them more often, and the group get-togethers I had (w/ my foreign friends) in public parks were, in fact, very low-cost and a lot of fun.

As far as my criticism, in the Bay I was friends with all different kinds of people, across many divides, and the majority of them were unfortunately stuck in the bar/club paradigm. The foreigners being the only ones who were more open to other activities.

With everyone having their own experiences, at different ages, with their own social groups, it'll be quite hard to discuss the whole topic w/o comparing individual observations.

"Maybe it's not related to being in 2015, maybe it's just that after 25 in modern societies it gets more difficult to get close to people."

Being a student used to mean being a teen, and that gives maybe a decade to party before the biological clock starts ringing and nobody can party all night because they have little kids. Sure, outliers always existed, but they were rare. Post teens were adults with adult incomes but not adult responsibilities, like kids, for quite a few years, usually.

The modern economic strategy of extending childhood by about a decade by extending education and eliminating entry level positions and near elimination of the high school grad career path has all kinds of fascinating economic effect, mostly bad, but one big effect is by the time the advanced degrees and internships are done and someone finally has an above poverty level income and medical insurance and a place to live other than parents house, the biological clock is ringing and if you don't immediately start popping out newborns, you aren't going to have biological time to do it, thus dramatically limited party culture.

So lets say culturally theres a shift from the delay between "I graduated and now I'm an adult" and "I got a herd of kids and after school stuff to attend and kids sports and ..." used to be a decade and now its maybe two years? So you'd naturally expect a decline of maybe 80% in party culture, taking it from dominant activity in the 20s to its basically gone?

There is also the biological effect that scenes from the movie "Animal House" look like fun to a teenage brain, maybe not so much to an older brain, so increasing the drinking age and dramatically criminalizing drinking while also socially pushing the mantra often heard on HN that its impossible to socialize (party) without being an alcoholic (which is criminalized) will result in a natural decline in party culture.
Same story for the Netherlands I guess. We do house parties in our twenties too but usually it's for an occasion like a birthday, not just random having fun.

There's also a lot of the 'meet around 9-10, have some drinks, light food and music at home until about 11:30 when you turn down the noise, all bike/taxi to the city centre and start hitting some pubs around midnight and stay there until the clubs fill up with people around 1:30 or so and stay until 4, maybe club-hop inbetween and then all go your own way home. The house party is more of a place to meet collectively, to get some drinks in 5x cheaper than in a club and talk to people while still sober and in a relatively quiet place, a pre-party really.

By the 30s nobody really hits the clubs anymore (at 24 I've pretty much stopped already), plenty of parties at home though but usually there's no dancing involved which may tell you something about the nature of the party.

I believe it is considered a redesign, or incremental improvement by most people, and the article is trying to imply that but without just repeating the phrase it just used.
I see it as a high/low level oversight. If people don't know who controls the project and how to measure the progress on it, then who would even care about technical reports? That's like checking the details on a body with a head missing - maybe the guts are OK, maybe not. He's dead anyway.
The drinking age in the U.S. is 21, and is very heavily enforced. It's a lot easier to drink underage in someone's house than in public.

well, time to find out who has failure tolerance built in to the architecture 8^)
I'd guess it's a wee bit difficult to provide that: [saying this as a designer/illustrator with a deep interest in the subject] Soviet design inherited rules from artists involved at the start of the revolution, and was formalised via government-run technical schools and propaganda bureaus, so there was a constant stream of highly public stuff in this style, which covered print, architecture, products etc. In the US, bar propaganda during the war, there was never close to the same formal propaganda structure, so though there are are isolated examples, it was always more ad hoc: good design/illustration was always commercial (as a side note, classic sci-fi/popular mechanics covers were very heavily informed by Soviet space propaganda posters). Closest you'd get is probably postage stamps. NASA has some stuff archived, but it's not the same, it's just prosaic designs with stuff like a photo of the crew of a mission. I assume it wasn't promoted with the same religious fervour in the US, no creation of secular ikons
Unfortunately I'd have to disagree. Production applications belonging to paying customers are completely down - I don't think "Elevated Build and API Error Rates" quite does it justice.

Note: The applications in question have had zero interactions (deploys, restarts, scaling, etc.) which might have caused their dynos to be unallocated/re-provisioned within Heroku's own service.

Very unlikely that it's a facebook company, the money they're making is nothing at the scale of facebook. It's more likely they don't have access to the official API, they've just reverse engineered the instagram iphone/android/web app and are using that to like/follow people.

Here's a copy from the status page.

3:00 AM PDT We are investigating increased error rates for API requests in the US-EAST-1 Region.

3:26 AM PDT We are continuing to see increased error rates for all API calls in DynamoDB in US-East-1. We are actively working on resolving the issue.

4:05 AM PDT We have identified the source of the issue. We are working on the recovery.

4:41 AM PDT We continue to work towards recovery of the issue causing increased error rates for the DynamoDB APIs in the US-EAST-1 Region.

4:52 AM PDT We want to give you more information about what is happening. The root cause began with a portion of our metadata service within DynamoDB. This is an internal sub-service which manages table and partition information. Our recovery efforts are now focused on restoring metadata operations. We will be throttling APIs as we work on recovery.

5:22 AM PDT We can confirm that we have now throttled APIs as we continue to work on recovery.

5:42 AM PDT We are seeing increasing stability in the metadata service and continue to work towards a point where we can begin removing throttles.

> “We’ve gotten a lot of requests from property developers who want to place it in a few filthy rich neighborhoods of course, and I tend to say no to these right now,” he says. “I think that it should be in a public space.”

I love the idea if it's really as healthy and good as the article makes it appear. But it immediately saddens me to see such a short-sighted attitude.

Why not sell it to the 'filthy rich' and then with that money build some more in public spaces? In the end you have more air purifying towers than if you only built them in public parks. Not to mention that, obviously, air moves around. So it doesn't much matter where you put the things.
Hah! No need to meter the power used to know they'd achieved their goal by a large margin.

I found the interview of him I was making my comments from, here's the critical 2 paragraphs (http://queue.acm.org/detail.cfm?id=1716385):

SF The ARM was conceived as a processor for a tethered desktop computer, where ultimate low power was not a requirement. We wanted to keep it low cost, however, and at that time, keeping the chip low cost meant ensuring it would go in low-cost packaging, which meant plastic. In order to use plastic packaging, we had to keep the power dissipation below a watt—that was a hard limit. Anything above a watt would make the plastic packaging unsuitable, and the package would cost more than the chip itself.

We didn't have particularly good or dependable power-analysis tools in those days; they were all a bit approximate. We applied Victorian engineering margins, and in designing to ensure it came out under a watt, we missed, and it came out under a tenth of a watt—really low power.
This is manifesting itself as downtime for a lot of companies, including Heroku: https://status.heroku.com

If you want alerts on this sort of thing, my side project StatusGator https://statusgator.io will alert you when services post downtime on their status pages. My dashboard blew up this morning with a ton of red and yellow as soon as Amazon started flaking.

Edit: I suppose it's time to invest in a multi-region setup. Since StatusGator is hosted on Heroku in the US-East region, it is in theory affected by this problem though so far is still up.
This brought up an interesting question - how much paper is recycled vs trashed?

Atleast in the US, 67% of paper was recycled in 2013. So 2/3rd isn't burned or compacted. Thats pretty impressive.
Why not public key cryptography?
I think that is the one thing about all of this that saddens me the most. There's definitely enough talent to make such a project function, and yet we totally botched that up completely. I've known teenagers in my younger days who've created much more complicated projects in shorter spans of time.
Alpha had all sorts of exotic load intermediate and shift instructions to help with this. 64bit registers, 32bit instructions, I forget the exact number but you only had 20ish bits of immediate value.

It seemed like slightly more of a chore then, with x8664 you can use memory with a lot of instructions..

Nope, there is not any support for VB at this point in time. It's C# only I'm afraid!

As cloudroutine mentions, the older omnisharp-server implementation is NRefactory based, whilst omnisharp-roslyn (as the name implies) has been built atop roslyn.

omnisharp-roslyn retains a bit of NRefactory (the code actions part[1]), which was called NR6Pack and has now been renamed as Refactoring Essentials [2].

Anyway, there's been a lot of recent changes in the works, as someone has already mentioned, omnisharp-rolsyn currently has an open PR [3] which will provide a plugin system to omnisharp-roslyn. Once introduced, it will mean that the various omnisharp editors/clients can pick and choose which plugins they wish to bundle with their editor. This may include F#, VB, Cake, Fake and many others.

New contributors are, as always most welcome :)

One of the more successful, though still brutal, experiments in handling crime, in my opinion, was the penal colony in New South Wales, Australia:

https://en.wikipedia.org/wiki/History_of_New_South_Wales

From 1788-1792, it started out tough with thousands of professional criminals ill-fitted for the skills required. 1/4 of the 2nd fleet lost their lives. The rest survived near starvation. However, between 1810-1821, it transitioned from a penal colony to a budding free society.

I can't think of many successes like that in our history where so many career criminals were reformed so quickly, the sacrifices of lives not withstanding.

This seems like another reason to not rely on Amazon-specific services, other than the obvious vendor lock-in.

At least in the event of an instance outage you could conceivably migrate off Amazon to another VPS provider. No one using DynamoDB has an alternative.
Not even that, the domain already has a certificate, they're forcing a redirect to HTTP on a domain that already has a certificate.

Listen to music? Talk? Pass a joint around? Those that played instruments brought them and would jam.

I know I'm getting old and was kind of a prole but most parties that I went to in Atlantic Canada were like that, you brought what you could afford and the people holding the party provided the venue.

You had strangers at the party because friends would invite their friends who'd bring some other friends. One never knew if the party would be huge or a bust.

We were relatively poor students so food wasn't common unless people kicked in for a pizza or went out for donairs, whatever was plentiful and cheap and easy.

The worst parties usually involved alcohol, I spent New Years Eve (1989) cleaning a walk-in kitchen pantry at a friend's flat because my then-girlfriend had barfed in it after she ran to what she thought was the bathroom. I was a bit disillusioned with parties after that.
Good book on Ruby on Rails?
I'm already familiar with Ruby. Is there a good book on Rails that is also not too old? Thanks.
I appreciate the detailed response! My use case is yet another indie web, run-your-own-server kind of thing that processes content my friends post online (from tweets to shared articles) and can predict whether or not it is relevant to me based on extracted topics, source, my context/location, and whatnot. Both the source data and training data comes in at a trickle (though I'm pondering ways to propagate training data throughout friend-of-friend networks) and is processed in the background rather than on-demand, so my performance characteristics are very different than most of the use cases I've seen.

I'm trying to keep the system frugal with memory but liberal with persistent storage, since you can run a commodity instance 24/7 and mount a pretty large volume for fairly cheap. It'll be slow, for sure, if there's only one user for each installation it won't need to worry about handling many queries per second.
In Europe I feel most talk is still on connecting Norway to say Germany with new electricity lines to utilise Norway's natural pumped storage potential.

Another interesting development recently was the creation of electric diesel. The economics don't seem to make a lot of sense yet but I don't think they've hit the efficiency limits of what is possible yet. The interesting thing is that it's carbon neutral (assuming the energy going into the process is carbon neutral, e.g. when excess renewable energy drives energy prices negative at moments of the day) probably works on a massive scale, and immediately allows existing fleets of combustion engines to become more sustainable. I'm not sure how fast these factories can turn on and off production but I'm assuming it's pretty good.

The efficiency is pretty low, electricity to diesel I've heard of efficiencies of 13%. And then a diesel engine itself is only about 30% efficient, compared to electric engines of > 90%. It makes more sense to invest in storage solutions and an electric car fleet, but if we do get significant excess renewable energy that is difficult to store, combined with ediesel becoming more efficient, then it becomes an interesting idea. Particularly for all the transport that is hard to electrify (airplanes, trucks), carbon neutral synthetic fuel made with renewable electricity could make sense one day.

I'm mostly optimistic about electrifying cars though. The next-gen top electric cars are getting close to ~100 kwh storage (today it's more like 80-90). Cars per capita in OECD countries is probably around 0.6 - 0.7 or so. That's a lot of storage if fully electrified, about 60-70 kwh per capita. Daily residential electricity usage is probably about 10 kwh in OECD countries. Of course that's when you electrify the entire car fleet which is a ridiculously big task (today's new car sales tend to be sub 1% electric), but if you can do 5% within a few decades, you can create multiple hours of storage which would be a huge impact on the ability to balance intermittent energy sources, without having to invest in storage for the sake of storage.
