Ask HN: Innovations in merchant online online credit card processing?
My client is a private small business brick and mortar. Their Point of Sale service/platform has a web widget for online ordering. Customer is redirected to the platform to place an order for pickup or delivery.

Recently we had a chargeback claiming fraud. The merchant processor asked for proof of EMV chip processing. Of course, that is a nonsense question with online purchase—- our claim of fake fraud is lost before it begins.

We reached out to our POS Rep to discuss the situation. Their response was: Hey. Face it. All credit card transactions involve risk. You have to look at chargebacks as an expense.

Apart from the credit companies, what efforts are merchants taking to combat fake fraud claims for their online stores and make successful claims in light of the liability shift?
Most of the devops (side question, is SRE technically devops?) people I work with are programmers who know a lot about test+build frameworks, CICD, cloud resource management, etc.

I don't think it would be appropriate to call someone copy-pasting templates, manually adding VMs, etc. "devops"
Looks interesting. Then I saw the data collection disclaimer during the install wizard. Deleted it in a instant.

You lose many potential clients just for that alone
Arguably, though, Sage and Octave are more geared towards numerical computing than data science

Sage is not really aimed at numerical computing, even though it can be used for that. It's primary use case is more towards computational algebra and number theory (and related areas) and is generally more focused on features needed by researchers and academics.
Can you elaborate on oral posture and articulation? I have a major snoring (apnea) and breathing issue due to dentistry mistakes (taking out teeth when I should not have as a kid) and my face caved in which compresses my breathing.

Also anyone else find this article annoying to read?

The poor do not see it that way. Years of fieldwork across the globe have led Ms Arora to conclude that when it comes to getting online, “play dominates work, and leisure overtakes labour.” Where people planning development strategies imagined, metaphorically at least, Blackberries providing new efficiencies and productivity, consumers wanted the chat, apps and games of the iPhone. Worthier uses tend to follow. But they are the cart not the horse.
Great idea to get a work up and find out about any deficiencies in the mix of stuff in your blood.
Sports is probably very specific. Amateurs will mostly buy what professionals recommend, or what their coach wears. These days you see sports stars and brands through social media and on TV, but in those days less so. Going to clubs, track meets, talking to the professionals/enthusiasts/hardcore fans, he would’ve been talking to the equivalent of Instagram influencers today.

Palantir is pretty well known for giving algorithms problems so it would have likely been solved by a cursory google "palantir software engineering interview"
"integer" as a type is less offensive though, as it only has one intuitive deficiency compared the mathematical definition (finite range). Where as "real" as a type has many deficiencies... it simply does not contain irrational numbers, and it does not contain all rational numbers in 3 respects: range, precision and unrepresentable due to base2, and for integers it can represent a non-contiguous range!

Oh yes; in North America the data pricing is far inferior - and in Canada it's particularly atrocious.

It's partially the population distribution; we have a paltry 35mil people in the 2nd geographically largest land area in the world. Now, much of the population is clustered, but still - infrastructure is spread out, expensive, and the cost gets passed down. Plus the competition is sparse and companies like their profit if they can get it.

In short, none of us would historically dream of downloading large stuff through mobile data. My data roaming is permanently off, and I only download through wifi. Some people even have phones with no data plans, or a paltry 50MB. 1GB was considered extra large data plan until recently.

(As a tangent, it's also been a historically painful process just to get started here too; in Europe, I'd land, go to the nearest shop, get a SIM card for $20, and I'm off to the races. In Canada, you need to sign a long term contract with 3 years of obligations, go through a credit check, give ethem all sorts of personal info, and pretty much blood and DNA samples... ;-( )

It's a discrepancy people have been waking up to last couple of years and starting to exert pressure, so it's getting better - but very very very slowly.

In a few months I'm going to be sniffing around for embedded software engineering positions (c on microcontrollers, DSP, maybe even some PCB or FPGA design).

I'm still buying a copy of cracking the coding interview and doing leetcode in the weeks leading up to applying for precisely this reason. It's dumb but I'm not going to give up an otherwise promising opportunity in protest, although in the interview I might politely ask (after solving the problem) what relevance it has to the job, just to make the point. ("I thought I was a applying to do X, and this doesn't seem to fit the job description. Does the job involve a lot of work like this?")
It's more important to remember the theme of an opening than the specifics of the multiple lines sprouting from it. For instance some openings revolve around having a bishop on a strong diagonal and an important central square or two to hold. If you remember these themes a lot of the available moves become (relatively) easy to work out, because you know why the moves are made in the first place. The best thing you can do is find resources that cover the themes as much as the lines/moves themselves, some of the Lichess studies are good, some just cover moves though which isn't helpful.

I've played a lot of people that go down 12 moves of an opening they remembered only to falter as soon as their memory runs out. It's very common, and you will always run out.
Careful, the mask is slipping.
> The universe is full of puzzles that mean something to solve. Why not work on those instead? Why would those be less interesting than a contrived set of rules?

Can you give some examples? Most things I'm aware of that could be classified as puzzles require, at the very least, enormous time investment, if not specialization, and there's often lots of drudgery along the way.
Yes, especially since we are fully compliant with CCPA, and GDPR. I can push one button and have all of your data deleted if you so wish.
If you are self-experimenting to figure out if X nutrient makes a difference, supplements are vastly easier to work with. Dietary changes are far, far more complex and introduce many confounding factors.

If you establish that, yea, verily, magnesium helps, dietary changes to make sure you get enough magnesium can make sense.

I used to take about $300/month worth of supplements of various sorts. I no longer do so and haven't for years. I just note that "Based on x, I need more of thus and such." and tailor my diet to get what I need.

Remember that it depends what type of Magnesium you take. Not all are created equal. I recommend Doctor's Best High Absorption Magnesium. Since taking that one for many years, digestive issues massively improved with slight improvements in sleep and overall mood.
If you're playing with magnesium/calcium i think boron should be included as well. It will allow you to utilize magnesium/calcium.
Anyone want to discuss that?
It's not like that at all.
An actual study would be quite a bit more competence than most pick-up artists display, I think. Whether it would be successful (produce particularly high odds)... well, I doubt it.
There are things and services out there that I'm pretty sure I would find interesting and valuable, but that I don't know about. These things I wouldn't mind seeing an ad for, if delivered without being too disruptive.

However, browsing the net without an ad blocker these days is like having unprotected sex with random people in some alley behind a bar... it's just not safe.
I wonder about the terminology of calling these "errors". That implies that there's a mistake, when really floats are among the most accurate ways to represent arbitrary real numbers in a finite number of bits.

Another way to phrase it is that a single float value represents a range of real numbers, rather than a single real number. So 0.1 stored as a double precision float really represents the range of real numbers from roughly 0.09999999999999999862 to 0.10000000000000001249.

I find it much easier to just study those problems when I interview versus complaining on the internet. The bar is damn low for most leetcode problems and refreshing is not that hard.
As Italian I could try to give you an explanation about the difference between North and South Italy.
Basically it derives from the unification process, during the last part of 19th century. Someone thinks the South payed more in this process. Someone else argues that it depends on economic and political differences present before the unification. North was an ensemble of little states, South a large state related to Spanish monarchy.

The first author has a publication called "zinc lozenges as a cure for the common cold" here: https://www.ncbi.nlm.nih.gov/pubmed/19906491 and given that the author has his own "research institute" I'm highly skeptical of this guy's ability to do science. Seems like some kind of crackpot

Data costs in the US tend to vary quite a lot from place to place - it's a big country with pretty bad infrastructure across most of its area, especially the less-populated places - but yes, that's the reason.
If you're depending on open source software then you also need to be able to fix the code in question. And do so in a way which the project would accept. Otherwise, your bug report may linger until the end of time.

Probably less than 1% of ads are the "make people feel inadequate" variety. You can see this for yourself. Pick 10 random companies you remember the name of, and look up their current FB ads at https://www.facebook.com/ads/library/. And you can certainly be an "ad man" without going that route (I don't make ads like that, myself).

The way to understand American policing is very simple, "Race".

In general this is true of many other things about America that may not make sense to Europeans. All other explanations are extraneous at best and more likely, disingenuous.

The current system of law enforcement almost from its inception was setup to protect whites from various "threats". Through out the history of the country these "threats" have taken various forms, be it native Americans during early settlement of the country, slaves, Urban crime or more currently immigrants.

When you understand this core purpose of American law enforcement, it will start to make sense :)
You can argue these points and prove mathematical efficiently all you want, in the end, it's about those who control the purse strings.

Usually workshops are a good place to find folks at your level, and those that go are usually eager to connect, and maybe even start a critique group if that is what you want.

You can also try larger cons that are aimed at your vertical, but I’ve found that workshops attract people who are more actively engaged in improving their craft. Those are the folks you want to mingle with.

> and not giving us any realistic way to opt-out

The opt-out model is inherently incompatible with the desire to not be tracked. If the default is that everyone is tracked, and you need to opt out, then just setting a flag in an HTTP header isn't enough, because your digital traces encompass far more than your HTTP requests. In order to make sure you're not following people, and not just browsers, you need to set up some sort of universal identification for adtech to. . . wait for it. . . track.
I guess there is a disconnect where some people don't think dev-ops people are software engineers and others do. I fall in the latter camp and have never worked with devops people who weren't also software engineers
Not sure, but it seems the conversation here is the difference between the parcel of land (land) and the infrastructure/ home on that land (property). Japan values the land so highly compared to the total property, houses are essentially worthless but the land it sits on is the true store of value.

This leads to some interesting results: very few old homes and constantly updating neighborhoods. As new residents tear down old homes that have become out of fashion, dilapidated, or just because the construction market is so efficient. And the construction technology with pre-fab components and nearly constant demand is an interesting result.

Contextual advertising (what you’re describing above) is a lot less intrusive than hyper targeted advertising.

I've personally had great success with this particular product. At the end of a long day of coding, when my brain seems "burnt out"/fuzzy, 20-30 drops of this in a glass of water has an almost-immediate and noticeable impact (most of the time).
> Another way to phrase it is that a single float value represents a range of real numbers, rather than a single real number. So 0.1 stored as a double precision float really represents the range of real numbers from roughly 0.09999999999999999862 to 0.10000000000000001249.

But the range is different for every number, it's not a constant error like precision epsilon. I think "representation error" is reasonable name, as it's used when describing the error in converting representation between base10 and base2.

> I wonder about the terminology of calling these "errors". That implies that there's a mistake, when really floats are among the most accurate ways to represent arbitrary real numbers in a finite number of bits.

If you only care about the irrational portion of real numbers maybe, but for rationals this is definitely not true, you could use a format based on fractions which unlike IEEE754 would contain no representation error compared to base 10 decimals - in fact they would even allow you to represent rationals that base10 decimals could not such as 1/3. Inigo Quilez came up with one such format "floating bar" [1]. There are advantages and disadvantages to such a format (e.g performance). But in terms of numerical error I doubt IEEE 754 is best, for representation error it is definitely not (and I say that as someone who likes the IEEE 754 design O_o).

If I make a sale in Norway for 100 NOK:

Business VAT: 20 spent (20 %)
80 NOK left.

Income tax: 39 spent (max ~49 %)
41 NOK left.

VAT on purchase: 8.2 spent (20 %)
32.8 NOK left.

67.2 % taxes.

If I spend my money on gas/diesel then I would have ~16 NOK of value left. (84 % taxes)

About 18 % of the income tax I'll get back during my pension.

So 90 % is probably achievable on some things in some countries.

Good old fashioned crackpot science...
In my previous job we had hired a windows system administrator with no coding/scripting skills whatsoever with title as DevOps engineer, he didn't know anything about what developers do and CI & CD practices. So he ended up just managing updates (manually) on vms and restoring backups . But i see this more of a failure of management rather than the guys fault. Management heard a buzzword, and hired based on what they have hired before.
