Bluecode Payments | Senior Elixir Developers | Austria | Full-time | Remote

Bluecode’s vision is to build Europe's leading mobile payment network and to fundamentally replace the outdated US focused card-based infrastructure, leveraging European data protection principles and direct access to the bank account.

Bluecode is accepted at over 18’000 locations in Austria and Germany, from large and small department and supermarket chains to famous events like Oktoberfest.

Last year we partnered with Alipay to let Chinese consumers pay with Alipay at every Bluecode enabled merchant and we have even bigger plans for this year!

We are looking for a number of talented developers to grow our existing teams. We are passionate about good software development and modern working practises that we are constantly iterating on.

Our tech stack is mainly Elixir, for DB we use Postgres, for frontend mainly VueJS and TypeScript. Our infrastructure runs on Kubernetes and bunch of other things like Terraform, Docker, Vault, etcd, Prometheus, Grafana, ElasticSearch, Kibana, Fluentd.

We also have a few more specialised Elixir roles we are looking to fill

- Security focused Senior/Lead/Principal developer
- Automated testing focused developer
- Fullstack developer comfortable with VueJS or React

Janitors usually aren't going to enter the bathroom and start cleaning until someone leaves as a courtesy. He was waiting a long time for Lendrum to leave, apparently much longer than a usual amount of time for someone to use the shower room. The janitor finally gets to go in and looks like no one actually used the facility, the shower floor is dry. he goes to empty the trash and there's this weird box sitting in there. I think I'd be a little curious if I was him. I don't think the janitor was sitting there keeping track of every traveler's comings and goings but he was just trying to get his job done. Although, I have a feeling that airport workers are at least a little bit trained to be on the lookout for drug/animal smuggling and human trafficking so the egg would have been a clear sign that something isn't right. I'm sure 99.999% of his job involves mundane cleaning but he's still trained just like everyone else to "say something if you see something".

One cannot copyright facts else the first one to blurt out a truth would be the only one allowed to speak it. The fact that the truth contains facts about an artistic endeavor doesn't make the actual data about reality an artistic endeavor as the recording of those facts is in no way creative.

If you filmed yourself walking around like an airplane you would own the clip. Blog about it and you own the article. But the space you occupied at 10:35AM last Thursday is a singular indisputable fact with not an ounce of creativity. In fact more to the point even what they have is actually facts about their own equipment like which tower you were close to at that time which its hard to imagine you owning.

There are laws designed keep people from collecting and misusing your data in countries not run by morons. There is no reasonable way you are going to acquire this same privacy and protection by trying to misuse copyright creatively. I'm sure actual lawyers are likely to regard interesting legal theories the same way engineers regard interesting theories on how to make engines run forever for free via magnets.

> replacing the glass panes with transparent LCDs or LED displays

I guess the CM-1/2/200 machines are the quintessential example of this. The Cray-2's cooling system isn't an active display, but it gets style points too (IMHO).

(But...I've worked in a few places that used glass windows (or other glass surfaces) as whiteboards... That's really what I was thinking of. :-) )
I thought Yelp was basically dead? I essentially only use Google reviews.

I don't trust Yelp. But I trust Google even less. Yes, maybe the Google Reviews people are siloed from all the bad things happening elsewhere in the company. But as far as I am concerned, anything with Big G's logo on it is automatically suspect.

> But to get to the Sun, you need to subtract 100% of Earth's orbital velocity.

Yeah, one would need to substract 100% of velocity if it wanted to land on a surface of the Sun safely, bringing the ship to a full stop. But why might one bother with the slowing down, if ship will just get melted by the heat of the Sun? You need just to rotate a vector of velocity by some clever gravity assist maneuver.

>humans are more monogamous

Extraordinary claims require extraordinary proof. Got any citation for that?
> It sounds like: Hitler was a vegetarian. Don't be Hitler.

To me it read more like the Nazi comparison was meant as a wake up call, and the bulk of the argument is in the second paragraph: "In this study[0], there is no human research, and the definition of monogamy is limited to a single mating season. It's also looking at gene expression, which means that a gene that everyone has is either turned on or off. For reference, genes are expressed differently in various parts of your body, and is a fairly good test for various types of cancer."

On a separate note, this wasn't a "Hitler was a vegetarian" thing. Pseudoscientific rationalisation for why some humans are morally superior to others is precisely that sort of context where Godwin's Law doesn't apply.
In other words, techcrunch is jealous of facebook. At the end of the day, it's one terrible ad-selling crapware crying about a "better" ad-selling crapware.

And it's not just facebook, it's an industry wide ( or even an economy wide problem ). It's everybody - google, microsoft and yes, even apple ( despite what their fans think ). And of course techcrunch and the rest of the media.

I guess I was wrong about the end of the anti-facebook clickbait media stories this year.

> Afraid of negotiating a price? Really?

I'm not afraid of it - I'm just at a disadvantage in terms of information. When I fly into some random city where I don't know anything about what a normal taxi fare is I can't negotiate can I?

It's also just something I don't want to do - I don't want to have a stand-up argument with someone about money, thanks. I also don't want to unblock a toilet but that doesn't mean I'm somehow afraid of it.

But some people are afraid of a negotiation, yes. A vulnerable person, stuck somewhere alone in the dark getting into a belligerent argument with a taxi driver could be an extremely frightening experience.

Taxis also requires you to carry physical cash, which again makes you vulnerable - to robbery. And again that probably is much more of a concern to people more vulnerable than you.

> To me uber is just an extension of the habit of calling your parents to pick you up after soccer practise.

Good? That was a great system when I was a child. It was safe, friendly and didn't involve any cash. If we can replicate the same great system for independent adults that's fantastic.

I wouldn't say any API. More like, there is a class of problems and a style of api design that models the resources very closely to how they are represented in the database - and you often find them in web apps. The style is quite common though.
How php is handled by Homebrew has changed last year. Now you do
brew install php@7.1

It was my understanding that if you wanted in your PATH you just did `brew link --force php@7.1`. That's not possible anymore? (Since MacOS provides a php binary) What's the recommended way for easily getting a specific version of php in your PATH?

Except you can't compare the utility of things from different classes like bananas, hammers, cars, overcoats and paintings. It just doesn't make any sense. Finally "utility" is a different way to formulate the same thing as "use value" as opposed to "exchange value".

In Marginalism, you compare utility from agent to agent but you can never attribute an absolute value.
what can be very bad is if the database provided api is really just a sql executor - binding you to the database without you realising it. Doing rest, but finding you just tied all your clients to your database representation

Snap's glasses were a fundamentally useless product. Augmented reality glasses could be quite useful.
I always hated using terms like "orbital velocity" trying to explain things to people who don't know what it means.

The analogy I use is imagine you have a ball on a string. If you spin that ball around your head, so the string is tight, how hard do you think it would be to hit a friend with it? Now how hard would it be to hit yourself with it?

A friend, you just let go! The ball is already spinning and WANTS to go flying out further away. But to hit yourself? You are going to have to first stop the spinning, then pull it toward yourself, or just pull repeatedly on the string harder and harder until it spins faster and faster until it hits you. It's a lot more effort!

It may not make sense at first, but it's easy to forget that earth is spinning around the sun pretty damn fast, and to get near it you need to first stop (or GREATLY reduce) that spin, that orbit, and only then can you start to approach it.

Glad to see Nim on HN again.

For those of you who haven't tried the language out, I highly recommend it. I have even been suggesting it to students who want to get out the mainstream language bubble (C++, JavaScript, Python, etc.) so that they can learn something different. They have really liked it!

> utility functions will never describe an individuals preferences perfectly (hell you couldn’t perfectly describe the utility of any of the transactions you make) but they’re useful when describing and predicting aggregate behavior, especially when fed a lot of consumer data (higher confidence)

I think you're describing some sort of regression there. I don't doubt that regression is a useful tool. But in that use case I think the notion of 'utility' is redundant: if I want to predict aggregate behaviour, I just collate some datapoints and stick a line (or logit, or softmax etc...) though them. Why do I need to concern myself with whether my regression approximates the agents' 'utility'?

I think game theory shares a flaw with many other constructs in economics: in the real world, it's actually quite rare that the payoffs are given to you. Instead you have to hypothesize payoffs that hopefully kinda-sorta reflect your preferences. There's a lot of theory about optimal behaviour in games, but in reality the hard part is setting the problem up.

As an example, I used to build trading strategies for a hedge fund. We'd usually optimise the parameters of a strategy to try to maximise its Sharpe ratio. But the strategy's Sharpe didn't actually reflect what we wanted to achieve. A 20% gain was nice and would get the team paid, but a 20% loss was an existential threat to the company. We were never able to find a 'utility function' that encoded that information without introducing all sorts of other weird artifacts. In the end, we just used a Sharpe ratio and accepted that it didn't actually encode our beliefs.

I'm just checking site via portable browser (while main one has blocked fb stuff) at the end of each month if someone from list wanted something and that's since December 2016. I don't own newest devices (Nokia 1320 with unsupported fb application) so I'm not logged anywhere else.

I stopped trying Nim in 2017 when I found out that the only worth feature were the macros. Red flags I saw:

* A return variable within procedures that works in the same fashion as an assembly routine with a registry

* Mutable strings

* Mutable everything

* Hate speech against functional concepts in the community (with all the related biases that this brings)

* Some arrogant community members were tolerated just because they wrote popular blog posts on Nim implementing a fashionable pet project.

* no clear consistent design direction

* too many pragmas

* too many pascal syntax mixed with other language syntaxes

* no module namespacing

* modules worked not much better than C libraries... (I am generalizing)

* poor ecosystem made out of incomplete mutable libraries

* python 3 (without any library or optimization) was faster than compiled nim to count words on a moderately large text.

After I realized about python was easily beating Nim in spead and readability only with the standard library without any optimisation on python's side (and Nim being fully compiled), my interest on Nim went down to 0. I thought there were other places were I thought I could better invest my time.

Did something from that list changed? is there any reason to look at Nim again in 2019? did someone here had a better or different experience than mine?

Well said. I like small and light phones, not iOS. I'm typing this on an Xperia X Compact (2016). Follow up models weight more and maybe the product line will be discontinued. Even the iPhone SE is dead.
I love that (well, and Breakfast of Champions) so much I could never get into his other novels much, because they're not them. Sirens was the first novel that I really connected with. I've read it so many times. "It flung them like stones." Ha, come to think of it, I was in a band called The Ghosts of Saturn, my brother was in one called CSI (ChronoSynclastic Infundibulum).. Isn't there supposed to be a movie coming out soon?

Once years ago I was in a 2nd hand bookshop in Sydney, and could hear a few staff members chatting excitedly in a back room. They were laughing over plot-points in Sirens! I listened for a long while, without revealing my presence. It was glorious. :-)

It just occurred to me to recommend to anyone who hasn't seen it the movie Gentlemen Broncos. I hadn't associated that and Sirens before, but there are many similarities. It's totally sci-fi, totally hilarious, and has a kind of Vonnegutian sugar-coated melancholy too. 5 stars!

Why would they divest now all of a sudden? As far as I know most of the Chinese money went into Toronto houses anyway, though I am not sure why.

As far as SF - everyone there seems to think they will never lose money on real estate and it will pick back up within a year or two whenever it drops.

SF was weird to me - I expected it to be a huge city, and it's this town with a cool bridge, expensive park, a bunch of overpriced houses, and a scooter app which gives you a distinct map of the "bad" neighborhoods.
No no, totally fine with "starter motor" and "bastard"
I think there's perhaps a misunderstanding.

You are correct that under classical assumptions of logic ("normal" mathematics), the Dedekind Cuts and Cauchy Sequences indeed result in the construction of isomorphic objects.

However, under constructive assumptions of the logical axioms of mathematics, such as intuitionism (not accepting the law of excluded middle, i.e., assuming that the statement "P and NOT P" is not necessarily true for all P), the construction of the Dedekind Cuts and the Cauchy Sequences may result in different objects, i.e., it may no longer provable that they are equivalent.
> Especially since homebrew force-updates itself and there's no way for users to avoid these changes.[1]

This is not true. `man brew` documents how to disable auto-updates.

> Why exactly is this kind of purist decision being imposed on users?

Because there's a lot of current debate about whether things being relicensed under the Commons Clause is "open source" or not and we'd rather lean on an established, well-documented authority on what that definition is. Additionally, part of our agreed membership of the Software Freedom Conservancy (who help us with a lot) involves ensuring our core formulae are open source software.

> So you're going to periodically make maintenance changes to my system without my permission. Goodie.

Again, `brew man` documents how to disable this.

---

The complaint behind the individual complaints is "why doesn't Homebrew work the way I want it to". That's a reasonable complaint and there may be better tools for you to use rather than Homebrew but we're going to continue to build Homebrew to work in a way that works best for the majority of our users and avoids our (entirely voluntary) maintainers having to deal with the same issues again and again.

> I'm afraid I don't understand your point. There won't always be a linear function representing the same > preferences and anyway 'ordinal' utility functions that represent the same preference order mean the same thing, so they make as much sense.

I've become a bit unsure about this myself (see below). An ordinal utility function only represents the underlying preferences according to the representation condition

(1) u(a)≥u(b) iff. aRb,

where "R" is the underlying weak preference relation, i.e. a complete preorder relation. For finite and countably infinite domains no further conditions are needed, for uncountably infinite domains you need additional conditions (Debreu 1954).

The scale of an ordinal utility function is, according to S. S. Stevens terminology, called an ordinal scale. It is characterized by admitting all strictly monotone increasing transformations.[1: 64] That means that whenever u(x) is a utility function representing R, then u'(x):=au(x) for real number a>0 also represents R in the sense of (1).

Question to you: Does it not follow from this that for every nonlinear utility function representing R in the sense of (1) there is also a linear utility function representing R in the sense of (1)?

For the countable and uncountably finite domain this should be easy to prove, since a linear utility function can be constructed for any such domain and any R. But I admit I don't know how to prove this for the uncountably infinite case. The way I put it, we'd have to prove that there is strictly monotonically increasing transformation of any nonlinear function into a linear function that preserves the order defined by R. I thought this was obvious but maybe I'm wrong. :/

> They use cardinal utility but they don't just assume it. The assumptions (implicit in a lot of cases, admittedly) behind Expected Utility are generally the Von Neumann-Morgenstern axioms (relating to ordinal preferences over probability distributions over outcomes)

So they assume these axioms, that's what I'm saying. Not assuming them would e.g. be actually measuring preference intensities in decision makers (by direct scoring?), or eliciting preference difference comparisons of the form u(a)-u(b)>u(c)-u(d) from decision makers and having good independent reasons for them to make sense.
