I'd also like to remind anyone using DynamoDB: it cannot store empty strings. Let that sink in for a second. If you think you're going to be able to store JSON documents you'll be in for a nasty surprise when you try to insert a valid JSON document and either the request fails or it converts any empty strings in your JSON document into nulls.

Not sure what you're responding to.

How are you arguing that people who are beautiful don't have more options for mate selection, or that intelligent people aren't more likely to accumulate wealth?

I understand the difference between r vs K selection, but that seems like a non sequitur in response to my previous post.

That sounds very interesting, but I'm curious about the pass mark criteria. Is there some larger number of beta and gamma that can also pass? Otherwise, it seems like generating Beta and gamma scoring gives some nice measures for use by the teachers/students, but if ultimately passing only relies on alpha, it's a lot like any other math scoring.

It becomes a little like companies saying they value x & y, but take action only aligned to z.
I've taken several rides in Uber cars, and, as it happens, always as one of 2 or 3 passengers. Some of them have been Priuses. I wouldn't doubt that, for those specific rides, emissions have been less than other options I had. I'd be curious to see the actual data before jumping to conclusions one way or another.
My bad, it was Left in Seattle. My last international trip was Uber just for the fact that it was the only available service (and takes amex).
I can transfer from my paypal to another immediately. In Canada I can do interac transfers which take minutes between banks and in Europe you can transfer between banks instantly and free.

I can do a wire transfer today from my Australian account and have it in my Canadian account tomorrow. Same for US->Canada, US->Australia and Canada->Australia. So it definitely isn't always 3-5 business days.

I'm going to assume you're american? America has basically the worst banking system in the first world and a lot of americans don't actually realize how far behind their banking system is.

Cryptocurrency value transfer involves none of that if you already own cryptocurrency. But you almost certainly have gone through the traditional system to buy your cryptocurrency so you aren't really removing that inefficiency.

Adding to that the inefficiency in interbank transfers is artificial. Should crypto start to take off I'm pretty sure you'd quickly find that the traditional banking system finds a way to do instant international payments.

>and is confirmed in 30-45 minutes at most AFAIK.

My last bitcoin payment was unfortunately just as someone started to spam the network a month or so ago and actually took just under a week as my fee ended up being too low even though it was an acceptable amount when I initiated the transfer.
I think shinny is awesome, but for online dashboards for my company, Dash seems awesome for one reason: no R. :D

Don't get me wrong, I use R almost everyday in my analysis, but setting up a dashboard that connects to a remote data source is a bit of a hassle and quite tiresome to set an entire R environment.

Ill play around with it, but working with virtualenv + requests + pandas + dash will make it easy to easily prototype some dashboards...

I tried using Etsy only to have them close my shop due to my products "not being handcrafted" according to them. These were small things that I 3D printed and people were actually buying. They shut me down but allowed similar endless China produced products to stay. They were not too happy when I pointed out those China knockoffs. They also kept my money hostage from the sales I made.

I will never again use or trust Etsy and I discourage every small seller I know that makes custom things to stay away.

Dismissing CouchDB because it only supports pre-sharding is extremely shortsighted. It takes very little time to replicate from one db with 2 shards to another db with 3 shards, even on N nodes. Copying the *.couch files is the absolute wrong way to manage this especially in a production environment when those files will be constantly changing.

It is far, far easier to add nodes to a Cloudant/Couch2 cluster, set up realtime replication from db1 -> db2, then once the replication has caught up, at your leisure you switch your database connection in your app.
Do you really think network partitions are an edge case? Jepsen doesn't actually do anything particularly edge-casey -- it just introduces network partitions and verifies that the cluster doesn't do any crazy things.

(There are also relatively common cases it doesn't test, e.g. hard power-off.)
It's the latter. The JSON encoding example is actually a really bad example for this language because there is a huge class of JSON which it cannot easily be seen to encode, though you can probably make some exceptions. An example of the many undefined things would be:

{"abc def": ["123 456", 789, 101112, null, false]}

A better DSL for JSON would have to include actual data types or so,

obj
abc def
arr
str 123 456
num 789
num 101112
null
bool f

...or so.
> I somewhat agree that let's not forget that third-wayism was a response by the Democrats to being locked out of executive power at the federal level for the previous 12 years,

Sure, it made some sense in “I want my party to have this office today” terms, it just was tremendously destructive to the long-term prospects of the party and it's relationship to the grassroots base, and to the key policy interest that distinguished the party from the other major party.

> My memory of the 1992 election is that Clinton managed to exploit general dissatisfaction with a relatively minor recession and conservative disenchantment (and consequent core voter apathy) with Bush's pragmatic decision to hike taxes, along with the split vote on the right created by Ross Perot's candidacy.

Perot's candidacy was almost entirely anti-NAFTA, split the anti-Bush vote, and was fueled by the major-party candidate consensus on NAFTA. With an anti-globalist Democratic candidate, there would have been be no substantial Perot support. Clinton didn't leverage Perot splitting conservative votes, he fueled Perot taking anti-NAFTA votes that had no major party candidate to go to.

> I absolutely understand why the progressive left felt betrayed by the Clinton-Carville machine, but as an outside observer I think the notion that the Democrats would have got anywhere with a Eugene Debs style democratic socialist in 1992 (or any of many similar pipe dreams) is delusional.

The alternatives to Clinton in 1992 weren't Debs-style socialist, they were pre-Third Way pro-labor welfare state Democrats like the vast majority of the party's then-current Congressional delegation.

Yup. This was a very poor decision on Apples part.

Sort of a huge misunderstanding of culture.
It seems like they would only find out after the update has been pushed, though - ie, after the app has been broken.

Unless they have relationships with the banks now, and would be given a heads-up. Perhaps that's the case. It sounds like it may be.
FYI DynamoDB in last few weeks added auto-scaling:

Additionally they somewhat recently added an optional caching layer:

Sure they might find out an App Update was issued in the App Store... but they cannot possibly know what API changes were made without reverse-engineering the API's all over again.

Not to mention, once they discover what changed, now this service has to go make the changes on their system... meanwhile that bank doesn't work with this service anymore.

So the App is broken for some undefined period of time.
Funding works strangely in USA public education. Schools in any given district seem to have a "hull speed" when it comes to money.

Once a certain amount of dollars are actually reaching the class room, adding more dollars will simply see most of the additional funds absorbed by hiring more administrators, prestige projects like sports facilities, "classroom technology" projects etc.

To detect this limit, simply check the level at which teachers begin paying for school supplies for their students from their own pockets and then back it off about 10%.

Being an asshole (in some senses of the word) is necessary, it's just incredibly difficult to compartmentalize the good aspects of being an asshole (holding people to tough promises and standards, being unflinching in stating the truth to people's faces no matter how impolitic or uncomfortable) from the bad aspects of being an asshole (bullying, abuse of power).

There's a saying in our house (we're on rain tanks):

"If it's yellow, let it mellow, if it's brown, flush it down".

I don't disagree with your assessment but note that in 'school' the subject is taught from a text book which is a distilled version of the knowledge. Those text books get periodically rewritten. In an engineering organization it would be difficult to justify the expense (although it might be worth it!) to hire a writer to distill all of the learning that happened and the history of that learning into a text that could be handed to new members to bring them up to speed. As a result it is simpler and more cost effective to have a mailing list archive that can be reviewed.

Now it you want to create a product/company out of that practice, then you would build a system that would let people reviewing messages be able to 'vote them up' based on their importance to the over all work product. That sort of 'auto curation' would then let you scan just the list with a 'curation threshold' and just read the important bits rather than everything in the list.

That might be a good compromise between a dedicated historian/textbook writer and a list which had all the data but it was inter spersed with the occasional "lets gets the group together for a movie / which movie" discussion.
This is startup-ese for "Every single one of our users is breaking their bank's ToS, and we maintain plausible deniability by telling them to go and read complex legal documents themselves".

I can totally understand the motivation (particularly with PSD2 around the corner, which will mandate banks to provide legit APIs - I'm guessing the plan is to grab market share before that happens). However, I am very skeptical of
this approach when applied to finance. Any technical product whose risk profile is "break into us and steal money directly" is a really dangerous place to leave your users on the hook for liability.
I think history suggests that governments are easier to reform than international financial interests.
You clearly don't live in NYC. Uber absolutely changed how people in NYC get around.

Whether or not they fill the same requirements, they made it so easy to get a car that it was easier than standing on a street corner and hailing a yellow cab.

And aside from that, they added accountability. Yellow cab drivers were rude, the cars were moderately clean at best, and generally took opportunities to rip people off. I remember leaving my phone in a cab around 2008, I immediately called it and the dude picked up, said he was around the corner and to meet him outside. He was more than willing to give me my phone back- for $60 and had a shit eating grin on his face. I had the same thing happen in an Uber about 5 years later- the guy dropped the phone off at my house free of charge with a smile.

There is a reason that NYC taxi medallions have pretty much halved in cost since Uber started here- because they are directly competing with yellow cabs!
Sure, but they've got plenty of buffer time since their app doesn't break when the new version is released, it breaks when the old API is actually depreciated. Just because you release a new version on the App Store doesn't make clients with old versions of the app disappear.
I am discussing perception and social behavior, not reality per se. That may be the case but that's not how people see it when their jobs are being destroyed.

Wealth also brings the luxury of long-sighted thinking. When you're poor the only concern you have is getting out of poverty right now.

To be fair, Romans not only mastered glass manudacturing (which in itself pre-dates them), they more or less invented (or however the material was first made during their period) "transparent glass" and - more than that - they invented "pressed glass", i.e. they were among the first to be able to mass produce glass objects, by blowing glass into pre-made moulds, JFYI:

http://www.ancient.eu/article/592/

So, they would have been able to produce glass jars alright and would have probably used (like it was done for wine and amphorae ) "sealing wax" together with cork (and/or some resins):

https://vinepair.com/wine-blog/history-wine-transport-8000-y...

And BTW, they were quite good at making airtight cans, too:

https://www.theguardian.com/uk/2003/jul/28/artsnews.london

(though most probably it would have been far too expensive to mass produce them at the time).
This is accurate, all of the ether that bancor owns it can do whatever it wants with - the investors get nothing except a centralized token (BNT) that Bancor can control completely (create, delete, etc, see https://medium.com/unchained-reports/bancor-unchained-all-yo... ), the investors do not get equity or insurance or any other similar guarantees.
Outside of my office window, there are always groups of them starlings chatting about. They get extremely noisy.

But not their "trade secrets". It's striking how little is publicly known about how each vendor's self-driving technology works. This is a technology that's grown up since the anti-patent "America Invents Act", and, as a result, there are few patents and much mystery. On rare occasions, someone gives a technical talk, but papers are seldom published.
I emailed a bit with sjtgraham on this a while back.

It was my understanding back then that even when Teller does more advanced authentication with the bank, eg EMV CAP, that that does still grant them the rights to move money, even though Teller doesn't yet support it.

To me that paints a big target on Teller's back - all those juicy downstream credentials.

sjtgraham's point was that setting up new payees typically (always?) requires additional authentication. But I can think of a number of scenarios where a hacker might send all my money to all my existing payees just to mess with me/Teller/my bank... causing fees and stress.

Obviously it's going down the route that Teller won't need your full credentials, you will grant them access via something like EMV CAP, which I applaud.

But I would call on Teller to publicly commit to not integrate more 'advanced' auth methods if they don't include the ability to grant read-only access, if the user wishes!
Ha, yea I've heard of numbers like that. I remember talking to someone at re:Invent who described their high five figures monthly bill in almost reverent terms -- it made sense after he described their 200+ MySQL server catastrophe DynamoDB replaced.

We actually ended up engineering our system to use a variant of event sourcing. This let us dump DynamoDB and use RedisLabs and S3 in such a way that we were able to handle 1mil DAU with a 10:1 write/read ratio for around $5k/mo -- including front end/backend instances.
> >I tend to assume the service was also poor, and they earned exactly the tip they got!

> 99.9% of the time poor service is not personally the customer service employee's fault.

"If you hear someone complain about a tip" is the important context that you removed. Maybe the employer is responsible to train the CSR that you should not complain about tips, or lack of tips... I don't think so. I think your parents should teach you that. I think it's common sense. If you got a tip, you should not complain about it. I don't think that 0.01% of people _complaining about_ their tips to the customers are responsible for it. That's nonsense.

If you did not get a tip, you should not complain about it to the customers! If you are regularly complaining about your tips, or lack of tips, it is a sign that you are providing bad service, and you should improve. If there is a systematic issue, you are understaffed, the kitchen staff sucks, etc... I can concede it's not your fault, but it is going to result in a statistically significant hit to your tips, and you should see if you can get them to improve.

If I ask for a sandwich without tomato and you bring me a sandwich with tomato, the same person who complains about having to make the sandwich again because they got the order wrong, is the person who complains about their tips. The one whose service is habitually bad, because of their attitude.
Right, but number of hands and fingers doesn't form a bell curve in the first place.

This is a really bad tactic, even if it's just a rumor, it'd devastating. Exerting a level of control only breeds contempt, Amazon now has free leeway to gain more partners and give more AWS credits.

Not to mention Walmart already has a reputation for being the bottom barrel brand, they can't compete with Amazon on price, Amazon even has leeway to increase the value of its products and services and say "we're not Walmart".

That's simply not true. Very few people have criticized Uber for breaking absurd incumbent-protecting laws.

The vast majority of people have been criticizing Uber for breaking laws related to fraud, stalking and harassment, and a generally toxic workplace culture.

The product that Uber offers is good (and no one other than taxi medallion owners is really arguing that). But they've gone about delivering it in an unnecessarily bad way.
