sadga··on Google Maps now has schedules for 1 million public transit stops
Google has had Seattle bus schedules for years, and OneBusAway has tracking, not schedules. Schedules are useless.
sadga··on Why Facebook comments is a bad idea for your site
Why does someone who'se never used my site have an opinion on it?
sadga··on A New Way To Solve Linear Equations (over finite fields)
Nit: A closer analogy is rationals, more so than reals (as reals have other unrelated properties like uncountability)

That is, given your simple rings (the integers) and finite rings (modulo n), you get fields by introducing just division (integers -> rationals; mod-n -> mod-p for prime p).

sadga··on Facebook loses 3 more executives
$50K over 5 years, not so much. 100,000 shares, maybe.
sadga··on Quick and Clean in Go
Missing generics -- it doesn't destroy type safety, it just forces the developer to write boilerplate variations of every method.

The official stance on that issue is: yeah, but it's better than the hassle of supporting generics (compiler effort, object code size/slowness, and excessive high-level abstraction (a bad thing in the Go world).

I have a foot on both sides: I miss generics when I'm writing one-off low-scalability code, but it's nice to have the speed of low-level Go code, and perversely fun to actually spend some of my coding time writing all those low-level sorting and array-building routines that are the meat of programmer interviews.

Now, when a candidate asks "When will I need to write a method to sort the keys of a map?", I can answer "Every time you use a map[string]T for a novel T!"

I hate novel T now. (<-- This is also a design feature of Go, the passive pressure to not use large hierarchical types, and try to do your work with just maps and slices of primitives)

sadga··on A sudoku solver in 33 lines of Clojure
Confusing post. It's an example of core.logic, not really an interesting Sudoku-solver, as all of the logic is in core.logic
sadga··on Stuff Harvard, MIT, Stanford & Caltech People Like
Article title should be "Reverse index of where people went to school who talk about various topics".

Obviously, the author chose a more wieldly title, but a far less correct wrong.

Ugh. Behavior like this encourages more obnoxious teaser sites like this, that profit from abusing people's natural curiosity. These sites are barely a quantum leap above spam.
sadga··on Craigslist now asks for exclusive license when posting
Yeah, it seems like weird wording, asking for confirmation that they can sue, without establishing the basis.
sadga··on Mac Malware Spies On Email, Survives Reboots
Why is the source code using StringBuilder everywhere instead of "+"? Is it designed for an ancient version of Java? Or is that some decompiled version?

sadga··on HelloFax (YC W11) Launches HelloSign to Take On Electronic Signature Industry
Not everyone who works with electronic signatures reads HN or TechCrunch, though.
sadga··on Final Fantasy comes to Ouya
More than decade-old. The prime properties are FF3 - FF7, which are 15-20 years old.

sadga··on Mobile game devs: Middle-aged women are taking over the iPad
Um, it gets worse. Apps are classified by how much the writer thinks the app is girly or manly, not actual usage numbers. The writer put all puzzle games in the girly category.
sadga··on Mobile game devs: Middle-aged women are taking over the iPad
HN doesn't appreciate concise one-liners. You need to wrap your claim in a wordy anecdote with some explanatory flavor, to give readers a sense that you put a lot of thought into your typing.
sadga··on Why Do We Expect So Little of Our Youth?
Funny, that we have movements like Where's The Math lamenting that math education is collapsing because classes are doing "discovery math" (AKA goofing off and chit-chatting), instead learning fundamentals and practicing to memorize basic skills.
sadga··on And then the music stopped
The blog is "Signal Vs Noise". There was never a promise that Signal would win.
sadga··on And then the music stopped
Facebook didn't have to sell stock to comply with regulations. They only had to file paperwork. They IPOd to get the benefits of the IPO ($$$), since they already were facing the bulk of the paperwork requirements.
sadga··on And then the music stopped
The problem is that individuals invest in funds whose managers chase these fads -- or who invest in broad market indexes. It's hard to find a "no hype" fund to invest in, especially when individuals have their hands tied by employer/government plans that don't offer owner-directed investments. (These 401-K and other non-defined-benefit schemes always seemed a scam to me -- in order to enjoy the tax benefits of saving for retirement, I have to invest only in the funds whose manager bought the fanciest lunch for my HR director?)
sadga··on Google Talk for Developers
You are aware that Skype requires the Skype client, even less standards-based than Chrome, and everyone can use it? You can use Chrome and Skype alongside your web browser of choice. Chrome is spritually like the Mozilla/XUL of old -- it's a platform for apps, not just a web browser.
sadga··on Why Apple's new ads look like Microsoft made them.
Hodgman is an pleasantly entertaining comediam. It's hard to appreciate him while loathing his character.
sadga··on Zuckerberg's Big Facebook Mistake
I don't know why you are surprised. Forbes is not a reputable publication. It's "People Magazine / US Weekly" for people in the business world. It's not Bloomberg News.

sadga··on Google Fiber Plans & Pricing
Who doesn't have a gigabit NIC? They've been standard for years.
sadga··on Google Fiber Plans & Pricing
Airline bankruptcy is a normal business activity, akin to an occasional server refresh in the data center.. It doesn't disrupt the overall airline industry, and it's not a catastrophe to a bankrupt airline.

sadga··on Of Google's First 20 Employees, How Many Are Still There?
Forbes has an agreement with Quora.

(But yes, to your point, Forbes is not a "journalism" site.)

sadga··on The first open company
Considering Googler guys never even published their thesis... they went commercial pretty quick after hitting their idea, and dedicated the largest portion of their lives to the business end.
sadga··on Even experts get it wrong
It's written explicitly in the U.S. Constitution:

    To promote the Progress of Science and useful Arts,
    by securing for limited Times to Authors and Inventors the exclusive Right
    to their respective Writings and Discoveries.
sadga··on An Amazon Education
$2000/yr for 4 years is $8000

In Washington State, an AA is 4 semesters * $1500 = $6000, completed part-time by people have jobs at Amazon.

The Amazon hate on this issue is bizarre.

sadga··on An Amazon Education
It's $2000/yr bonus for minimum wage warehouse employees, not spoiled engineers.
sadga··on SmartAsset (YC S12) Helps With Tough Financial Decisions Like Homebuying
Redfin already has property taxes and mortgage rates, it just doesn't bother to put taxes in the calculator, for unknown reasons. Doesn't have the credit score stuff, but that's not really relevant -- if you have poor credit, buying a house anywhere near your affordability boundary is likely a huge mistake anyway.
