It's difficult to test, because by not having credit cards a lot of fake orders are now excluded, lowering the conversion ratio that way.

So if I did a test of showing only PayPal to half of customers and PayPal + credit cards to half, the one with CC could win just because of the fake sales.
Besides being a super well-written and interesting series technically, the Call Me Maybe blogs have been very revealing as far as different organizations' response to criticism. Especially considering all of the target applications are open source, the project maintainers should be profusely thankful someone has taken the time for such thorough analysis, presumably much deeper than the maintainers themselves appear to have done at least on consistency behavior, to reveal bugs which should ultimately make it that much stronger.
You know when you have to create a separate section just to explain your name that is the time you realize maybe this was not such a good idea.
EDIT: per grandparent comment edit, this comment is based on a misreading of the article and should be ignored. My apologies!

-------

> By definition, snapshot isolation is supposed to guarantee that all reads are the consistent, committed data as of the begin transaction, and the commit will fail and rollback if any data altered within a snapshot isolation transaction was already changed

Absolutely. What it doesn't guarantee is that data that you read and then use to update a different location has remained constant - which is what write skew is in the first place. What InnoDB and PostgreSQL call 'REPEATABLE READ' and Oracle calls SERIALIZABLE are in fact snapshot isolation.

edit: to clarify, Aphyr's original article describes RR as preventing basic write skew, which mainstream MVCC-based RR implementations simply don't do. Postgres does prevent it when using SSI (the SERIALIZABLE level), and lock-based implementations (RR on DB2 and SQL Server) do also.

You can argue this both ways: The MVCC-based RR implementations do conform to the (fuzzy) letter of the ANSI SQL standard law. They don't conform to Adya's formal definitions, but in fairness many of them existed before those formalisations did :-).
I was under the impression that STARTTLS was the only implementation of SMTP over TLS.

If major providers do not respect the STARTTLS protocol and effectively make encryption mandatory that makes me happy. But as far as I know the standard says STARTTLS is optional.
Disclaimer: I work for Percona.

The docs are on the galeracluster.com page, which is owned and maintained by another company, so there's no way we could fix those. A staff member from this company (And one of the Galera authors) replied on the original 'Call me maybe' post indicating they would fix the docs, though.

I think the 'corruption vs inconsistency' debate could seem as nitpicking, but anybody who has been working long enough on databases has a very specific concept for each word, and, given transaction processing (distributed or otherwise) is such a complex topic, it does not help to use the wrong terminology.
Uhm, ... packages don't always have the same names on all distributions!

I've had the same issue and here is what worked for me. You might want to work on cutting back to zero caffeine, and work on drinking plenty of water and doing general diet improvement. If you're eating and drinking lots of sugar that can give you uneven energy levels throughout the day. Some grains like rice or toast in the morning for energy. Eating meals and/or snacks every 2-3 hours, and getting away from your screen for a mental break in the afternoon, combined with a healthy diet and some exercise cured me of my late afternoon sleepiness problem.
I didn't write this to comment to "knock the author down a peg". From the facts of the story, my sympathies totally lie with the author. But the way he comes off is as entitled and arrogant. There is no reason that I can't feel that Billy was in the wrong, but I also dislike the author's attitude.

I'm not so sure that I'm really an outlier, to be honest. I think the data that the BMI calculations are based on is outdated. It's the same numbers you see from New York Life actuarial tables from the 40s and 50s, when big chunks of the population experienced malnutrition.

Quite honestly, I have no idea how someone could be 6'2" and only weigh 148 pounds, which is the bottom end of "normal" BMI, according to the NIH[1].

"Its an experimental study, the number of subjects isn't really that important."

I'd be interested to understand why this is? My logical reaction would be that it's always important - as a crude example, surely doing an experiment on every single human on Earth would give you much more accurate results that on say 100 people, because you'd be sure to have covered all the innate variables that exist when experimenting with humans? (different metabolisms, etc)

I know a guy who is a hardcore triathlete. At one point a few years ago he was doing really well, sponsored athlete, over 210 pounds with only 7% body fat. He was at a regular check up and the nurse looked at the BMI chart, then looked at him and plainly said 'Maybe you should work out more'.

Just my anecdata that BMI is misused even in the medical community.

Now, 20 miles in a short ride is what, about 4000 reps, at quite a bit more than 4lbs. I mentioned this. She said "Lets just start out at 4 lbs and work up slowly".

Work Hard, Not Smart
I was in the winning team in SW once and another time in the second team. Story is very familiar. I think the key takeaway is that you should never take SW seriously. Hackathons are not the way the startups are built. It's not a real team and it's not a real startup. That's why Billy character here is wrong. If you have a real business idea and serious plans don't pitch your project in SW. In an hackathon, every team member should have the equal rights on the project, regardless of their contribution level. Just have fun during the weekend, share the prizes equally if you win. And after the weekend, just throw away all the code, the brand identity or any other IP. If some of the team members want to further pursuit the idea, they are free to do whatever they want starting from scratch. If you want to make a handshake deal before start, agree on these principals. I know its hard to think like that with all the adrenaline in your blood but this is the only way it would work out. So I think the 0.4% deal at the beginning was the first sign that this story won't turn out so well.
Hyper Growth of Daily Fantasy Sports Is Going to Change Our Culture and Our Laws
I was hoping this was an update to this project; bugfixes, or more examples, or docs. Very cool that this exists though.

@emodendroket "Isn't the fun of writing NES software basically doing it like guys would have done in the 80s?" - I did stuff in the 80s, there was nothing fun about having to leave comments out of your code for the lack of memory, or using a clumsy compiler and/or editor. Cross-compiling is the way to go! Just making these old systems do things is the point, and keeping them alive.
Some thoughts about creating a system like this:

Any successful implementation of comprehension must progressively enhance the world model based on additional information. Furthermore it must understand some basic rules, such as, "Any subject, set of subjects, or actions can be represented multiple ways."

So if you said, "Mary's brother is Sam," or "Mary has a brother named Sam," or "Mary's brother is named Sam," the world model must collocate the meanings "Sam" and "brother" for Mary and be able to respond to queries about either.

Further, if you mention that John also has a brother named Sam, and then you mention Sam in an ambiguous context, the program should be smart enough to ask, "Which Sam? Mary's brother or John's?" Infocom games did this; you are building a more flexible world model builder, but the parser would operate similarly.

There is also the concept of recency. If I talk about "John's brother Sam", ignoring the fact that pronoun references to "he" should be contextually mapped correctly, and then mention Sam, the program should not need to ask which Sam I mean. It would be like talking to someone who wasn't paying attention.

Finally, there is also the concept of confidence. In the face of ambiguity that can't be resolved, a confidence rating should be assigned based on available information and future answers should be based on that confidence.

I suspect that if someone were to create a language parser that could create a mostly-accurate world model AND modify itself based on new rules it read (e.g., "When some says 'he' after referring to someone's name, they are almost certainly talking about the man they previously referred to"), you would be 90% of the way to creating a useful virtual intelligence. It would of course not be able to reason or have opinions of its own, but it would be extremely useful as a virtual assistant that could learn your preferences over time.
I wonder if amphetamines and similar substances work in the same way. On speed for instance, people can stay awake and party for days on end without sleep; that would result in a tremendous push on the circadian clock, though I have an inkling it's not simple subtraction and addition.
The point is: learning to design or become a doctor takes passion, dedication, time and often money. To expect everyone to learn how to code, and to code well, on top of what they're already passionate about is counterproductive. Another point is: software will look a lot different if the experts in their fields can build their own.
The problem for them is: we are the powerful ones now.

...

We built this internet.

...

Actually, we are in charge now. You just haven’t realized it yet. Automate or be automated. If you don’t know how to map out complex systems. If you never got grounded as a kid for taking things apart. If you are too lazy or unwilling to learn our ways. If you don’t work for us yet, you soon will.

The above lines are absolutely cringe-worthy and take away from what is for the most part a decent account of the events. I can understand if someone temporarily holds onto such feelings due to the emotional shock of being wronged by someone else they consider a 'bully' (but really just sounds like an immoral/unethical businessman). However, if you actually hold onto this mindset day-to-day, I would say that is problematic.

Bitcoin is most definitely based on a material, but with the advantage that the material used in its construction is more varied. The material for construction is whatever material required to create and power computers to perform the calculations that mint currency and transaction blocks.

Government is "by the people for the people". If a set of people come together and agree to a currency, then you may firmly state that they have formed the minimal government needed to meet this requirement (even though I believe this requirement to be superfluous and arbitrary).

I think it's treated as a necessary evil. People are starting to realise that it's less necessary these days.

Anecdotally, back a decade ago it was common to see a Windows 2000/2003/SBS box in even an SME environment being a fileserver/exchange/intranet/AD box. Now, I rarely see one. In fact they're declining even in large corps.
I dunno, pushing the Nest was pretty obvious to me. Also I can't see why you'd want to turn it off totally. If you want the heating on permanently or off permanently just turn the temperature to an extreme value.
I hear what you're saying but didn't interpret things the way you did. Here's my guess as to your thinking. Please correct so I can see where I'm misinterpreting.

IMO, you think that everything that Billy did was clear and above board. That the engineers should have _understood_ that Billy was the one in charge by what he said and what he did. That he owned the idea and that they were there to implement his vision as they best interpreted it in order to get things off the ground. His "payment" for this would be: the win, the .4%, and the good times. The .4% especially made that explicit.

Also, it was clear that there was not necessarily any connection between Billy and the rest of the team after the event unless Billy thought they jelled and decided to keep things rolling. Otherwise they would part ways with everyone having had fun and the coders having gotten a reasonable "taste" if things did take off. Because of Billy mentioning the LLC and his partner.

I have a feeling this test is not so much about accuracy as it is tendency. I.e. they avoid entirely specific projections, instead they want to see if the effect can be observed even once and thus have groundwork for further investigation.

Depends on what kind of generality of statement you're trying to make. Here, the generality might be a cause and effect one in which case you're attempting to generalize over possible future treatments and you attack detractors who might yell "that was a fluke!" or "it wasn't the caffeine, but instead the presence of the doctor!". To do this, you design an experiment which carefully controls for all expected irrelevant interactions and then show a response which is significantly different from random variation.

You end up limited, as you note, to your population. 5 people won't defeat detractors who believe that this effect is limited within some, e.g., metabolic profile but it ought to give them serious food for thought as to how wide the affected metabolic profile actually is.

If these 5 volunteers were chosen at random, then the potential generality of effect can still be large as a detractor would be fighting, at best, with the notion that the 5 chosen were circumstantially susceptible to this effect (as compared to a study of convenience where one might believe that "college students" or "hospital volunteers" are especially susceptible).

So, in a certain sense, testing every human on earth improves the power of the statement you can make (not really its "accuracy" though maybe its "precision", in a sense), but in many other ways that may be too expensive for the kind of result the author seeks.

Am I the only one that thinks Bobby the poster is acting oddly, with odd expectations?

Maybe it's because I'm not familiar with norms around "Startup Weekend" type events.

I have no doubt Billy the pitch man is an asshole (almost all restaurant owners are, for one thing). I also think he's being completely reasonable being confused about why this guy he just met thinks he should own a piece of Billy's company.

But I confess I've never understood why anyone would want to go to a 'startup weekend' kind of thing and code for free on someone elses business idea, someone you've just met, in the first place.

I must be missing something about the general cultural expectations of such events.

But it does seem odd to have an event focused on starting businesses (and creating teams likely to work together in the future on the business?) among people who have just met, with no written contracts involved (even prohibited!) based just on cultural expectations which may or may not be shared, and no time to discuss them or get to know each other in advance. Do successful teams actually get created from this process sometimes?
