Big missing piece of this was clustered / HA configurations. To run a production level application, you’re going to be running with some sort of clustering or replication, which is going to add a pretty significant latency depending on implementation. But, interesting article, I’m always impressed some of these smaller database companies are still kicking.

I strongly second this. I've had some other projects get in the way, but I signed up for quantopian and have been very impressed with the things I have gleaned from reading others algos and postings. If your algo is really that good you get a cut.

In her own words via Twitter: “I retweeted @JPBarlow using offensive language in a sarcastic tweet that was meant to slap back at racists after Obama's first election. Eh, not my best retweet, even if the intentions, both mine and Barlow's, were in the right place.”

Reading the RT itself, I think it’s clear she is AGAINST racism.

I'm reminded of a great episode of "This American Life" that discussed (among other things) the fallibility of the polygraph. As depicted in pop culture, the lie detector is never wrong, but it turns out that's far from true. Well worth a listen:

I have only tried one algo trading platform, Interactive Brokers. API documentation: http://interactivebrokers.github.io/tws-api/index.html#gsc.t...

Their live market data is gated at 250 ms, so definitely not for HFT. Market data subscriptions are only $5 / month (US Equities, and others I don't remember), and commissions are low.

You can program in C#, Java, VB, C++, or Python. I use their C++ platform. It is not particularly pretty, but it seems well-tested and works. Perhaps most importantly, they have an awesome support phone number. They are responsive and very helpful.
Depends...

What instruments are you trading?

Hyperinflation can have positive effects too for the population: borrow money from a bank to buy a house, see the currency hyperinflate, pay off the debt with a week's worth of work. It's obviously terrible if you have savings, but for those in debt it is pretty good.

Sorry for being curt. But it's the professional responsibility of developers to educate themselves. Some people think they can cram on binary trees in CS, use that limited knowledge to BS the interview, and then coast into working on the transaction system at a bank or whatever.

If a company wants to pay you to mentor a junior, that's one thing. And should be explicitly stated as such. I'm willing to help just about anyone that asks. But if I find myself showing a developer how the compiler works (or a compiler works), or the syntax of our programming language, or basic things that Google knows, I'm going to walk away from that flaming wreck of a company. I've worked with developers that hunt-and-peck typed before. You ever have to explain syntax to a guy that can barely work a keyboard? Let's just say, my threshold for putting up with BS is dramatically lower now.
This is a pretty good idea. Something that scans tweets and other publicly accessible social media for a list of known words and then compiles it into a report for potential employers would go gangbusters in the HR/hiring areas. It obviously couldn't get everything, but would be a big help for employers.
Where did I say that?! I never said junior devs should work independently.

Anyway ,it's not about how people think the industry should work it's about how it does work. This is a fast industry, irl. People change jobs more frequently. Companies grow faster. Products go from conception to release faster. Financial horizons are shorter.

A big chunk of the 2018 industry did not exist in 2008. Mobile, for example. Not the companies, not the specializations. It's not philosophy. It's reality. I'm talking about side effects of this reality.

No one at Snapchat thinks "we'll hire this kid, he'll make a great engineering manager in 15 years." They do in some industries. We're on the other end of the spectrum.
You sound very confident. Why don't you short the cryptocurrencies you are sure are going to "come crashing down" to make a lot of money?
Tests help very much against regression. And if you have mixed people touching the code.

Anecdotal: I once helped out a team who was writing a Maven plugin for doing static tests on some js code during build. There was already a test suite with a bunch of test code. As my stuff was fairly complicated and I have a habit of writing unit tests for such I added a bunch. Fast forward a year and a half later: I was greeted with a mail that there was a bug in it. I had to fight the better part of a day to nail it down: First not being familiar any longer with the code and secondly because a bunch of stuff has been added meanwhile. I fixed and thought it was a good idea to add a test as it was a nasty corner case. I headed for the natural place where the test would go and found -- exactly the test I was going to write, nicely commented out. A quick check with Git revealed that I added this test initially, which then was commented out when the new feature causing the bug was added. Firing up git blame was next... This is why I am fond of having tests: you are stomped onto it if you break something at least if your test suite is worth its salt.
It does, however, become exponentially more difficult to double-spend, which is the whole reason we have proof-of-work security in the first place.

Interactive Brokers (IB) is your best bet. However, I’d like to reiterate as others have stated that you need to be prepared to lose it all (and moreover that you likely need much more capital than you realize to stay solvent on down swings).

Don’t take this the wrong way, but it seems like you haven’t done a lot of research into this: Interactive Brokers is one of the first things that comes up when you search on Google (etrade, Robin Hood or any other retail trading just isn’t credible).

Finally, is your 20 years of historical data for just open/close? Is that your execution plan? (Otherwise you can get really tripped up as you move to intraday trading)
2340 (the mandatory group project course) also covered a lot of this stuff, though not in as much detail.

The suggested reading for that course is a book that blew my mind when I first saw it as an undergrad: Clean Code by Robert Cecil Martin. I believe the examples are all Java, but the lessons are applicable to any language. Stuff like naming your variables more carefully than you name your children.

There's an Italian proverb that "one can never have a friend if one must have one without faults". Obviously, the degree of the faults matters, but your implication that friendship is a tacit endorsement of all the complexities of a person is extreme.

Edit: I feel this also applies to politicians. Sometimes I just dislike all the candidates for a given election, but for different reasons. And I have to choose which of my principles I value the most. It's awful! But it's reality.
Don't Waste Your First Slide
In your 2015 article, you criticized that the ArangoDB team restarted the instances after each test run. In this 2018 edition, they don't do this anymore.

I've long maintained a maxim that's something like "Look in the opposite direction of everyone else." So when everyone flocks to the bay area, get the heck out of there. When everyone says "I have no space for junior devs" think about how you can take advantage of that underutilized resource.

Junior devs are cheap. If you're willing to spend the time to sift -- and you will be doing a lot of resume sifting -- and setup a framework for mentorship, you can hire junior devs with more promise than your average senior dev.

Anecdotally, one of my junior hires from a few years ago earned his way through positions quickly and became a senior software engineer in just three years. I actually invited him to be my co-founder on my next venture and he turned me down :-P.
Am I the only one who wishes for the return of the Internet Cafe? If even better, the Lan gaming cafe?

There's something so nostalgic about back in the early pc gaming days, when my high-school computer club would do a lockin and we would eat pizza and have surge or blue balls and game the night away.

More on subject, the real problem IMHO is most coffee shops just don't have much room. The Internet cafes were always pretty big and usually had half high cubicle walls for privacy.

Few German stations have barriers. It's actually "profitable" in most cities to never buy a ticket, checks are rare. I guess German mentality helps avoiding widespread abuse (and the fact that it's a crime under German law).
Oh, that's another great point. There are different kinds of racism.

There's a great video from the 80s called "The Color of Fear" which has a bunch of randomly-chosen people of various ethnicities put into a room, who slowly start to talk about more and more uncomfortable subjects.

There's fear. There's lack of empathy for problems which don't affect you personally. There's even outright hate. These are different problems with different solutions.
> Yet there is no way to get ahold of google other than their product forums, posting and praying to not get a cheap canned response (which is what happened to me).

I believe the only way to get relief from Google is to know an insider, who can escalate to someone who can do something. All their public support channels are dead ends. Google sees you as a product, not a customer, and it's customer service skills are so bad that even if you're a real customer you can get the same treatment.

Stuff like this is why I switched to used Fastmail with my own domain.

> I used to LOVE google back in the early gmail/android days. They were the good guys. What happened?

To a first approximation there is no such thing as a "rockstar" developer. I mean a few of them exist, but the actual stars (not poseur wannabes) are already locked down doing other things so it isn't possible to hire them anyway. If you're hiring or building a team you have to target developers who are actually available, not the stars.
From my understanding of the "unintended acceleration" lawsuit, you could very well have had the exact same engineers who implemented the Toyota firmware :).
A marketer doesn't have to actually like advertising itself, its just a tools.

I think they clearly know that users hate advertising but this is not their concern, more important is if the advertising increase the sales/profit.

You have to see it from their point of view.

I hate advertisement too but if I'm a marketer I would gladly spam users all day long if it works.
This probably isn't so true for the pay email services, but I just wanted to note that these two things are by no means mutually exclusive. Plenty of services are more than happy to take your money and "make you the product." It's so easy to do on the web, few can resist.
Are you doing HFT trading? If so, then the FPGA could help. Are you just doing plain ol' algo trading then you wouldn't really need it.
From what I know of Zimbabwe's inflation, anecdotally, I can't imagine worse inflation. Makes me wonder if technology made it more manageable than the earlier inflation of Hungary. I could imagine having bar code scanners and comouter pricing would make it easier to update prices throughout the day. This would mean merchants still wouldn't want to sell earlier in the day, knowing they'd get more currency later, but at least the merchant knew they hadn't forgotten to put a new price sticker on that can of beans from this morning.

I mostly agree but it's also understandable on the part of the NYT. She wasn't really even on board yet so this probably counts as one of those battles that isn't worth fighting even if they they wanted to.

Not that it really pertains in this case, but personally, I'm pretty glad that there was no social media prior to my being an established adult professional in a role that made me very aware anything I wrote was out there for all to see and interpret.
> No real names, no user names, no IP addresses.

Well, don't record IP addresses in the first place? Or if you need ip addresses for protection against technical attacks like DDOS-attacks, then delete them as soon as possible.

What is so difficult about deleting a real name and a user name stored by you if the owner of that account asks you to?

> I haven't looked in to this example, but I suspect even the name of a client on a bill would be subject to the GDPR.

Common sense gives that data on documents you are legally required to store like for example invoices are exempted from deletion during the legal storage duration. After that, why not anonimize them or delete completely?

Things become pretty easy if the default becomes not storing any data, and only make exemptions from it after careful consideration if it's really needed, what private data it contains and how it has to be handled based on that.

Data is not just a resource, it is also a liability.
True, but there are many other market conditions in play there to be exploited, and a year or more of data is still useful.
It is not. Germany has a much higher population density, from pretty much any point within the country it's no more than 2 miles to the next village. And those tend to be larger than rural US villages, often 3,000-5,000 people. So public transport doesn't work as well in rural areas but there's generally some service for most of the population.

I'd argue that it's absurd that we still think 120k is a lot of money when we look around at how expensive things like property are.

My father, with a modest education and a modest first job, was able to get married, raise a child and buy a house near London well before he was 30.

Property in that area is now worth hundreds of thousands and would require a six-figure salary (supposedly a lot of money!!) to be able to qualify for a mortgage to buy.
For totally unrelated tinfoil-hat reasons I started using fastmail yesterday. Now I feel very vindicated in my choice, but it makes me wonder; since Gmail is so pervasive, will this action by them end up f-ing up email for everyone, the same way that many sites claim to only work on Chrome?
Getting Metrics from Postgres RDS with the Datadog-Agent Docker Container
I am working on the same thing. I'm still in the model building phase and I still need to complete my backtesting framework. You seem to be ahead but I've already looked into the trading API process.

Go with whatever broker offers a trading API obviously, and has a fee structure that matches your trading strategy. If you can afford to lose a bit on the trade through commissions and your strategy is swing trading then you can pick pretty much any broker. If you need specific fill times and commission percentages before your strategy pays off then you are stuck with Interactive Brokers ($10k minimum[1], low comms, fast exec) or Robinhood (low minimum, free comms, slow exec). And technically Robinhood doesn't have a public API[2] so you would have to do a little reversing of their app's messaging. And then there's terms of service... yeah. Probably not a big deal for a small fry like yourself.

Next would be testing. You've got isolated tests with historic data but try get a broker that has a paper money version. TDAmeritrade's paper & api is good (but they are expensive). To be clear you would be using your algo to trade in a paper money account. That lets you get more realistic trade tests and if you blow something up you are still ok!

Keep in mind Robinhood is free because they are paid to route your orders to hedge funds and they are re-ordered in the book. You will get ok price execution through them but never the best. One thing you should include in your backtests/simulations is order execution delay and fill price variance. If you place market orders they won't always fill at the quote price. If you place limit orders they may take a while to fill (or not at all) unless the price is within the other side's order prices.

Last is the pattern day trading rule. Make sure you have a strategy that won't make more than 3 day trades in a 5 day window, otherwise your account might get suspended for a few months. It's a pile of horses but you can get around that by simply having more money in your account. > $25k will buy you unlimited day trading privileges.

Just curious what your strategy is based on if you don't mind giving a few details.

Good luck!
