N.B. Despite the title, submitter is did not build the app; this guy did: http://news.ycombinator.com/user?id=progrium

According to the video, it's not a free API; it's 3 cents per message.

What does being 88 years old have to do with anything?

It means she grew up during the worldwide Great Depression, but was still old enough to have known its stark contrast to the prosperity of the 1920s. This could have influenced her towards extreme frugality.

She was also an adult before the worldwide adoption of Keynesian fiscal policy, so the idea of even temporarily running an unbalanced budget might be particularly odious to her.

jjs··on HTML5 Canvas based fast painting app
I abandoned pure standards-respecting HTML5/canvas while working on a similar tool (for pixel art, not general drawing), for reasons which will readily become apparent when you try to save a file... then load one.

Flash is still quite useful because desktoppy apps have legitimate needs which are thwarted by the browser's rather uptight security model, but are mostly satisfiable with Flash's controlled way of enabling them.

jjs··on ArcLite - Arc Ported to JavaScript
I guess I would be concerned about compiling to JS because you're adding another layer of abstraction on an already fussy language (when being interpreted by the browser). It's hard enough to find bugs as it is.

On the other hand, mechanically generating the code you've abstracted away will make sure you only get the same bugs every time. ;)

jjs··on Soon-to-Be Open Secret (Males in College Admission)
On the contrary, I stated that grades measured the ability to get grades, which is almost tautological.

Demonstrating anything beyond that would require proof, hence the burden of proof is squarely yours. :)

jjs··on Soon-to-Be Open Secret (Males in College Admission)
"If nothing you did in school had any relation whatsoever to the real world, you got screwed."

And, since no one ever gets screwed, we can therefore conclude that your original argument is correct!

jjs··on Soon-to-Be Open Secret (Males in College Admission)
Math, Physics, and Chemistry are easy to objectively grade, so I'd accept that they tend to have higher grade quality (a notional metric of the correlation of grades to ability) than e.g. literature, drama, sociology, pottery, etc, where the grade quality correlates to the ability of the grader.

Physics classes don't prove a blanket statement regarding grade quality over all subjects, any more than Yao Ming proves that Chinese people tend to be seven feet tall, or the King of Sweden proves that Swedes tend to be kings.

jjs··on Soon-to-Be Open Secret (Males in College Admission)
"Grades correlate reasonably well with ability."

... as measured by grades.

Then just crank up the gamma correction to 3.0, and your 3.5 out of ten is now a reasonably-attractive 7.0472987320648917 :)

jjs··on Ask HN: Which is the best way to keep yourself organized
Several of my gmail labels have a corresponding labelname-to-reply label.

I realized I was using my inbox for several functions:

1. notice urgent or topical subject lines

2. store items to read later

3. store items to reply-to later

4. store important already-read items for later reference

5. store to-do items, often implicitly as 2-4 above.

Once I set up the appropriate labels, I was able to move functions 2-5 out of the inbox, leaving it just for function 1.

jjs··on Buffett: Wealth, Estate Taxes, and the Ovarian Lottery
> If we cut capital gains taxes to zero and added an equivalent amount to corporate profits (say, a 40% annual tax rate instead of 35%), the government would make an equivalent amount of money from the same economic activity, and Buffett's theoretical tax rate would go down. Similarly, if corporate income taxes were zero and his capital gains were taxed at 40%, he'd pay much more than his secretary, but the government would collect the same amount.

Neither of these are equivalent. The "only capital-gains tax" scenario creates incentives for foreign investors in US corporations. The "only corporate tax" scenario creates incentives for US investors in foreign corporations.

The current scenario seems to be a "get some tax revenue from whomever we can" strategy, but it might be worth tinkering with the ratios, especially to determine whether a more capital-gains-heavy, corporate-tax-light regime might increase overall tax revenue, by altering in the US's favor the flow of foreign capital, domestic capital, corporate relocations, and corporate expenditures.

jjs··on Tell HN: Can we stop commenting on troll comments?
> I think it makes more sense for voting power to be associated with karma level.

This could be gamed, or lead to runaway karma effects within a small, incestuous cabal.

If I were pg, I would handle it similarly to amichail's suggestion, but instead of voting power going to submitters of articles that I like, I would have it go to voters of articles that I like.

In other words, I would restate the problem as, "I can't be awake 24 hours to moderate every single submission, so instead, I'll assign invisible voting power based on how reliably a given voter's running and recent preferences match what I would want to see on the front page."

I would add some random jitter to the algorithm, to mildly penalize people whose votes are too similar to my own.

The bonus to consistently good submitters would not be better voting privileges, but better submitting privileges (better initial placement and/or slower decay).

And I would silently give voters and submitters whose patterns negatively correlated with my preferences corresponding penalties, and use their poor taste as valuable data on what not to put on the front page.

Yes, you need a serious name, like "Google" or "Yahoo".

I suggest "Splooploo".

jjs··on What project are you working on during the upcoming holidays?
> These were all my bosses ideas.

When you already know a better, simpler, cheaper, and faster way to meet the stated goals, you can email your boss a counter-proposal, clearly outlining the advantages to your proposed approach.

This might be risky in highly political work environments (or with touchy bosses), but in general, they are paying for your expertise, not your typing skills, and a decent boss will recognize and appreciate your initiative.
