We took a different approach on how to engage end-users by designing our own DSL with a compact pre-processor (template engine) for basic control structures: http://apps.axibase.com/chartlab/14cf1974/3/ - Bas

Other than normal distribution assumption, there is another assumption that doesn't hold true for most time series related to human activity, nature, or scheduling. If heteroscedasticity is present, you cannot use the same standard dev

It maybe utopian or too liberal, but I'm against imprisonment for any kind of crime against wealth, be it shoplifting or securities/bank fraud on planetary scale. I think prison should be used for crimes against humanity, e.g. hom

Congratulations, Wikipedia! I found it tremendously useful over the years. I have one suggestion for them. I wouldn't mind making micro-donations for articles of particular quality and relevance to me. Say I find something useful and c

I have a lifelong edu address but it's not what they mean of course. My reading is that you have to be an enrolled student or researcher.

Note that they're sharing this dataset only with *.edu, which is unfortunate for the rest of us. I wish they would allow access to a fraction of the dataset, e.g. 5% of records, for the rest of the community.

It's not going to be as easy as you make it sound - getting rid of the application tier. Think of all the goodness that the Spring framework provides, for example. Do you anticipate all the modules will be taken over by a database?

They might extend the message limit to 10K characters, but they won't be able to stretch their users' attention span which is probably is bound by 2 or 3 sentences anyway.

The more SKUs I have sitting on the shelf, the more price reduction announcements I can make. The difference with Safeway however is that I cannot take those promotions back. On the other hand, why not? Should we expect to see AWS announce

Some of the comments posted here make me wonder about how broad and diverse the HN reader base is. The demographics are just unbelievable, if not surprising.

Why not close supermarkets out of respect for labor unions as well, for 2 weeks. I think the solution lies somewhere else - such as automating humans out of retail and services to the extent possible. For instance, speaking of gym, I would

I signed up for a gym that apparently went on an initiative to improve its employee culture. The gym is really nice, not as good as Equinox in Palo Alto, but close enough. So one of the initiatives was to close the gym during holiday season

Mike, I'm big fan of your work. Have been using it since early releases. I'd love to hear your thoughts on how to make visualization more appealing for non-programming users who want to interact with data beyond the basic clicks a

Unfortunately, CDN analytics is no alternative to GA so it's either/or kind of choice for us. Hence, full proxy type of CDN means that latency is additive.

There is lies and there is statistics :). For more reading on the subject, I recommend Beautiful Evidence by E. Tufte. He's a classic when it comes to infoviz.

I think what is often overlooked is that you can live in the US in a nice place and it will be cheap, at least by European standards. Assuming you can sort out visa issues.

The economic complexity chart is interesting. It basically says that all oil producing nations experienced a decade of rapid simplification. That's not what I think happened with the Gulf/Middle East nations with their forays into

I like analytics if the price is less than 50ms per request. We use GA and statcounter for analytics anyways. Charts that show how much static traffic you saved are nice, but with bandwidth close to free, it's not a big deal. CDN analy

That's neat, thanks for the fail2ban pointer. I wonder if there is something that would tail nginx/apache logs and compute aggregate request counts by response code, error code for monitoring/alerting. Not looking for log fil

We tried it, setup was easy, but our response time for dynamic content increased by 150 millis so it didn't work for us. It's worth noting that their model is different from CDN - they proxy all of your traffic through their own s

I need more of these just to remind me what winter should look like. It's absolutely devastating to have no snow whatsoever for Xmas.

That was misleading to me as well. Lots of entries have no dependency on Hadoop stack, other than the fact that you can use them in front, on the sides, and sometimes even in lieu of Hadoop projects.

It's probably good enough for consumer finance sites, but they should really factor in inflation. Inflation has been below average recently, so the margin of error is not that large, but still ~1.015^10=1.16 which means that price drop

Do you mean Informix Time-Series Extension? It's been around for a while so maybe there are existing things that came out of IBM recently. Last time I checked its schema it was basically storing serie as a blob not unlike OPC historian
