Based on my experience, I like the author's approach since it makes things pretty clear-cut and optimized the storage in the core table (in my experience as well, deletes happen frequently and the soft deletes are rarely touched). In large, row-oriented tables that that storage can add up and even with views/materialized views there's a cost to using/maintaining those as well.

Yeah, I checked it out and wanted to use but a bunch of regular old SQL queries don't work. Please add support for the old fashioned group by syntax! (This will be helpful for getting to a true drop-in replacement!)

my first reaction was, it looks like an HDR effect

Even if he's out as CEO he still will likely wield outsize influence due to his 1) board seat 2) equity stake 3) majority of leadership are presumably his people.

Will be interesting to see who replaces him and whether the company actually changes.

Just to confirm, is this a smart-phone based spectrometer? (Why don't they use that term?)

This CNC also represents what appears to be the best UI in almost any machining tool I've seen. Glad to see good design thinking not just get it done engineering.

I'm no physicist, but I think that while it may be theoretically possible to distribute power wirelessly doing so in practice seems like it will be necessarily dangerous so as to be impractical. To quote a previous comment I made on HN:

To distribute sound over long distances 'wirelessly' you need to make it loud. That typically means cranking up the power. And ultrasound can be harmful at high power [1]. [1] "Occupational exposure to ultrasound in excess of 120 dB may lead to hearing loss. Exposure in excess of 155 dB may produce heating effects that are harmful to the human body..." https://en.wikipedia.org/wiki/Ultrasound

Jon here - also worked on Data USA.

Several of the visualizations use data from ACS summary tables and the axis in several of the visualizations reflect the underlying buckets provided by the Census Bureau.

Used Pandas + Matplotlib to generate the charts. Looks at 2013 5-year estimate from ACS PUMS, using all rows where wage > 0 and age > = 16

There was a Media Lab project that did something similar 2 years ago -- and is open source https://github.com/JeremyRubin/Graffiti-codes

This was interesting story from 2014 http://newsoffice.mit.edu/2014/algorithm-recovers-speech-fro...

It's coming hopefully...http://www.netblazr.com/

Interesting that Kleiner Perkins is moving downstream http://www.nytimes.com/2015/06/17/business/dealbook/kleiner-...

You should consider a geo-ip lookup for an initial location recommendation, even if its not perfect.

If you have the time to watch, I've also found David Blei's talk on the LDA to be very interesting and clear as an introduction

So far looks like grbl flashed to Arduino.

What is the budget for your machine? I'm also very interested in CNC and interested to see further progress and part 2.

I'm not changing my habits from a study based on 12 people.

It's cheaper and easier for me to just lose my umbrella and buy a new one if that happens than to pay $60 upfront

Here are my unsolicited 2 cents on why not to work on Wall Street:

Solve real problems.

Don't be a second class citizen (e.g. if the firm is financial, software engineers aren't going to be CEO and that says something).

Make sure you have upside. Don't work in a job where your function is to maintain some legacy system and if it breaks its as if you lost the firm millions but if its running smoothly no one cares.

Interesting idea, personally I think it might be just a bit a head of the curve for general public at the moment. I think the rate limiting factors here are bandwidth/camera quality. As mobile data speed improve and mobile cameras improve as well this could really be a game changer and I can see even in a few years something like this really taking off.

my 2 cents from a quick glance: don't require users to login to use the site, let them at least search or find products.

Board games are great because they are one of the last refuges of shared attention.

I'm personally a big fan of Axis & Allies, Puerto Rico, Castles of Burgundy etc. There's something really nice about people coming together and focusing on the same thing.

As an alum of UMD I'm really annoyed by this whole situation.

While I was an undergrad there, there was an incident with social security numbers being revealed on parking mailers that were sent out (http://marylandrha.blogspot.com/2008/07/social-security-numb...)

At the time I was wondering why the heck do people sending out parking mailers have access to my SSN?

After seeing this article I'm again wondering why the heck does the university retain SSN for alumni?

edit: the reason I mention this is because I think having reasonable data policies in place can help mitigate the severity of such events

Are there health risks associated with extruding carbon fibers? I was under the impression that working with carbon fiber can be potentially harmful to your health.

My response is probably more emotional than logical and I think you raise good points but let me try to respond.

How much did he actually pay out himself in the end? Mozilo's worth ~$600M according to some quick googling. $67M represents ~10% of his net worth (some of which was gained illicitly). From a risk perspective this looks like a great deal! Cheat yourself up to a big fortune and if you get caught so what? You've made it! So I do think the fine should be on the same order of magnitude as the net worth of the individual to really send a message -- and it should not be tax deductible (if it is for individuals, I believe companies can).

I also think there should be a more serve and general ban from the securities industry.

Certainly should not be a criminal offense if bad biz decisions are made in good faith. But there ought to be severe, lasting civil consequences for grossly irresponsible risk taking in breach of fiduciary responsibilities. (More than an SEC settlement that just gets written down)

... and in the darkness (of Oracle) bind them!
