tsally··on Ask HN: How come so many of you know about stocks/finance ?
A lot of smart people go into finance and make a lot of money, so I think there's a general curiosity about their methods and techniques. Unfortunately the better you understand it the more cynical you'll get. :-p

tsally··on Ask HN: So What Universities Are Good?
Or instead of independently reinventing the wheel while living in communal apartments we could just choose to learn from people smarter than us who have already invented the wheel. I'd rather spend an hour of my time learning reductions from a really smart person than four hours independently stumbling through the problem. Indeed, the more complex the problems get, the less likely it is that the problems are even solvable independently. Seems like you are trivializing the process of learning. The time savings I get alone from having access to professors is worth the cost of tuition. Not to mention the research opportunities.
tsally··on Ask HN: So What Universities Are Good?
I only reject small schools when it comes to technical disciplines like CS. Size and funding make all the difference when it comes to the courses offered and undergraduate research opportunities. I actually prefer small, liberal arts schools for all other types of education. :)
tsally··on Ask HN: So What Universities Are Good?
You might be interested in this thread: http://news.ycombinator.com/item?id=901782. My response in that thread: http://news.ycombinator.com/item?id=901808.

A couple additional notes. If you're interested in creating things, a small CS program probably wont suit you. Those tend to be far more theoretical; what you want is a CS department with strong systems. You might also consider getting a degree in something else and minoring in CS and/or programming on the side. Finally, undergraduate research is accessible at any research focused university and I definitely recommend you participate. You'll have to knock down a ton of doors to get a position, but it's worth it.

Feel free to email me if you want to know anything else about UIUC or just have questions in general!

tsally··on Stereotyping women right out of science
That's not an accurate description of the research that has been done in the field. There's certainly not "more evidence for the biological side". Mathematical performance on standardized testing is quite similar (http://www.sciencemag.org/cgi/content/summary/321/5888/494). When people read that study many are quick to point out that there is greater variance for men than for women, however other studies suggest (http://www.pnas.org/content/106/22/8801) that could certainly be attributed to cultural factors. Just read the abstract:

"Using contemporary data from the U.S. and other nations, we address 3 questions: Do gender differences in mathematics performance exist in the general population? Do gender differences exist among the mathematically talented? Do females exist who possess profound mathematical talent? In regard to the first question, contemporary data indicate that girls in the U.S. have reached parity with boys in mathematics performance, a pattern that is found in some other nations as well. Focusing on the second question, studies find more males than females scoring above the 95th or 99th percentile, but this gender gap has significantly narrowed over time in the U.S. and is not found among some ethnic groups and in some nations. Furthermore, data from several studies indicate that greater male variability with respect to mathematics is not ubiquitous. Rather, its presence correlates with several measures of gender inequality. Thus, it is largely an artifact of changeable sociocultural factors, not immutable, innate biological differences between the sexes. Responding to the third question, we document the existence of females who possess profound mathematical talent. Finally, we review mounting evidence that both the magnitude of mean math gender differences and the frequency of identification of gifted and profoundly gifted females significantly correlate with sociocultural factors, including measures of gender equality across nations."

Let's be clear here though. There are indeed be biological differences between the male and female brain. Females may be better at certain tasks than males and vice-versa. The question is, is there evidence to suggest biological factors could play a significant role in explaining the extremely low amounts of women in science? Consider the fact that even if some biological difference in mathematical ability could be demonstrated, that wouldn't even come close to explaining the disparity. We're not trying to produce Nobel Laureates here, just scientists.

tsally··on Stereotyping women right out of science
Replace "med school" with your scientific field of choice. The general principle doesn't depend on the specific example. I only used it because the article's author did.

And as far as your question goes "is it really that simple?" In the context I presented (effective early education versus discrimination in the workplace), I personally believe it is that simple. Women with talents in the sciences wont be ignored simply because they are too valuable to business and society. We just need to figure out a way to produce more technically skilled women. While we're at it, we should probably figure out a way to produce more technically skilled men too. Getting people to go into technical fields is already difficult, it just happens to be more difficult with women because of social factors.

tsally··on Stereotyping women right out of science
Agreed. Were you under the impression I was arguing as such? I'm simply saying "men think and women feel" is a debate we were having a long time ago before the biological arguments for the lack of women in science were refuted. Now that the biological arguments have been proven to have no merit, the issues we need to be looking at are social.

Women are not being told they can't do science anymore (that's what the article seems to be suggesting). Instead they're being told they need to look pretty and live up to certain standards of beauty. Living up to these standards is a lot of work for young girls and doesn't leave much time for much else. Men on the other hand can neglect such standards and still be socially accepted. I can't even imagine what a woman would go through if she dressed like your average male engineer.

tsally··on Stereotyping women right out of science
This piece reads like a women's rights article from 10 or 15 years ago. We've moved on from this basic debate between thinking and feeling. To be honest I'm pleased that most discourse today is at a higher level. I appreciate the author's position, but "women feel, while men think" is essentially a solved debate as far as gender issues go. I don't think even the most idiotic misogynist resorts to that argument anymore (I might be underestimating the idiots). There are so many more opportunities for deep conversation on this issue, so it pains me to see the author take this approach!

As an aside, I'll point out any battle for women in science was lost long before women med students had to put up with their misogynistic counterparts. The issue is about the women who didn't make it to med school in the first place.

tsally··on Ask HN: What do you think about invite only membership on HN?
IMO being a part of a community for less than a year isn't a long enough snapshot to accurately judge trends in that community. The site guidelines recognizes this too: "If your account is less than a year old, please don't submit comments saying that HN is turning into Reddit. (It's a common semi-noob illusion."

In regards to your suggestion, invite only wouldn't work. All the accounts that submitted and up-voted the iPad articles are registered already, so how would switching over to invite only change anything in your scenario?

tsally··on Go To University, Not For CS
The problem is that the majority of CS is taught as a pure subject with a smattering of applied theory.

Curriculum wise UIUC actually does an excellent job of addressing this issue. I imagine other schools are similar. We basically have our three core theoretical courses and everything else involves programming. Every course that isn't a theory course involves several significant programming assignments. For example, in our networking course the final programming assignment (in C) is to implement TCP over UDP. We have a seperate course called Programming Studio that is required. The entire course just focuses on learning programming well. And students can opt to do a large software engineering project instead of a thesis their senior year (the vast majority do software engineering, not a thesis).

I think all these measures help, but despite the heavy emphasis on programming, a lot of graduates are still horrible programmers. I think the root cause is that we are still learning how to teach programming well; we've had a much larger head start on learning to teach mathematics.

tsally··on Go To University, Not For CS
Computer Science in the US is very similar. Just replace the advanced low-level courses with algorithms and data structures (we still do computer architecture and assembly).

Fair enough, but there's nothing overtly weaponizable about communication technology.

Reliable and secure communication technology is what enables the military to function. Without it, all the weapons technology in the world wont do you any good. So on a moral level, if you are against war you should actually find working as a researcher on communication technology more reprehensible than working on weapons. On an intuitive level I would guess that the breakdown or compromise of military communication has resulted in a greater loss of life than advances in robotics.

The reason why I'm pointing this out is that the real world isn't as simple as "a bunch of dickheads trying to strap guns to [robots]". You're making a simplification because it's convenient, but that simplification is morally inconsistent with approving of DARPA's work on the Internet. The fact that technology has a dual use is something we all have to deal with as researchers. But I don't think it helps matters by treating the issue as a binary.

tsally··on Happiness is earning $60,000/year
Can you elaborate on this? I'm really interested in the type of work that you did and your negotiating process. Was it software development? What type of companies did you work with?
tsally··on Happiness is earning $60,000/year
This article missed half the point and doesn't quite capture what was said in the TED talk. Earning above $60,000 a year doesn't affect the happiness of the experiencing self. But as Kahneman goes on to say, it certainly affects the happiness of the remembering self. So a lot of money wont affect how happy you are at a particular moment, but it does affect how happy you are with your life as a whole.
tsally··on Republicans' new Web site not exactly what they hoped it would be
If only coming up with a great political idea was as easy as writing a high quality encyclopedia article. Quantitatively there are several orders of magnitude more article authors than great political thinkers. If we place all activities on a continuum based on intellectual difficultly, there's a point where crowd sourcing stops working. I think it's pretty clear where political thought stands compared to writing encyclopedia articles.
tsally··on Attorney General Tom Corbett Subpoenaes Twitter To Identify Anonymous Critics
"You have maximum freedom of speech for political purposes. But if you have malice towards a person for political reasons, and are saying things you know to be inaccurate in order to hurt them, and you have hurt them in some way (perhaps instigating an investigation you know to be spurious) you've crossed the line and should be subject to civil action from the person you are purposely harming. That's not a criminal thing, but a civil thing."

I agree, but the US doesn't hold political figures to this standard. Two wrongs don't make a right, but the principle you outline isn't universally applied in the US.

tsally··on Let me Duck Duck Go that for you
In order to be qualified to make these sorts of comments, you either need to either (A) submit high quality links or (B) create something front-page worthy. Your last submission (out of a total of 3) was 59 days ago. And I don't see any links to projects in your profile. So pretty much all you're doing here is being negative; you're not taking any action to correct this quality "problem" that you perceive. DDG is an entire search engine coded by one dude in Perl. And it's pretty good too. I personally don't mind if it gets some time on the front page, even if just for the discussion.
tsally··on Another view of game piracy
Blizzard are successful because they created the first main-stream, polished MMO.

Blizzard was already incredibly successful before World of Warcraft. The foundation of World of Warcraft is the brand Blizzard started to build in 1996.

MMOs are the future of games exactly because the server component cannot be pirated.

I'm not sure what you mean by this. There are tons of private World of Warcraft servers. And you can be sure the same will happen for Starcraft 2. It's the social aspect of the server, not the server itself, that can't be pirated.

tsally··on C++ vs. Lisp
Well reasoned for the most part, but Lisp has occupied the high ground for development tools for a long time (REPL, SLIME, trace/untrace, step, describe/inspect, room, macroexpand). Other languages have been playing catch up in this regard as well. Whether Lisp still occupies the high ground today is unclear, but it is erroneous to say that Lisp programmers envy the development tools of other languages.

Ok, (1) Problems with the prison system and (2) underfunded child services compared to: (1) ending slavery, (2) desegregation, (3) women's suffrage, (4) free speech for extreme minorities, (5) freedom of religion for extreme minorities, (6) strong hate crime legislation, (7) landing at Normandy, (8) affirmative action, (9) free public defenders, (10) a right to a trial by your peers, (11) ...

The fact that American protection of the defenseless isn't completely perfect doesn't mean we don't care about it as a society. You gave two examples and then extrapolated from your small sample to claim American society doesn't actually care about the disenfranchised. I think you might need some perspective.

I was using murder in a colloquial sense, not a legal one. I'm pretty sure in England the legal term for what was done to Turing is constructive manslaughter (http://en.wikipedia.org/wiki/Manslaughter_in_English_law#Unl...). But IANAL.
tsally··on On Geeks and Gays
The argument I mentioned is concerned with psychological development not biological. I don't see how what your saying relates to the argument in any sense. Based on the argument, it would make sense to deny the adoption in your scenario.

To present the argument again, because homosexual parenting hasn't been extensively studied, we need to avoid homosexual adoption until a foundation of research can be established in this area. Research on developmental psychology guides many of the child adoption rules currently in place. The argument is that the same standard should be applied to homosexual adoption.

Again, note my use of distancing language. This isn't my opinion; I do not hold one on this issue because I'm not qualified in this area.

EDIT: The American Psychological Association has filed an Amicus Brief that is relevant.

"Because many beliefs about lesbian and gay parents and their children are open to empirical testing, psychological research can evaluate their accuracy.... the results of existing research comparing lesbian and gay parents to heterosexual parents and children of lesbian and gay parents to children of heterosexual parents are quite clear: Common stereotypes are not supported by the data... Some areas of research, such as gender development, and some periods of life, such as adolescence, have been described by reviewers as understudied and deserving of greater attention... There is no evidence to suggest that lesbian women or gay men are unfit to be parents or that psychosocial development among children of lesbian women or gay men is compromised relative to that among offspring of heterosexual parents... although a considerable amount of information is available, additional research would further our understanding of lesbian and gay parents and their children... It should be acknowledged that research on lesbian and gay parents and their children, though no longer new, is still limited in extent. Although studies of gay fathers and their children have been conducted (Patterson, 2004), less is known about children of gay fathers than about children of lesbian mothers."

http://www.apa.org/pi/lgbt/resources/parenting.aspx

Personally, seems like a reasonable standard of proof to me, but I think the people who hold the argument I've been presenting would say that the standard of proof necessary is up to the courts. Clearly there are areas that need more research, as the research is "limited in extent".

tsally··on On Geeks and Gays
Here's the logic of a non-homophobic argument I have heard of. The majority of research on parenting and raising children has been done with heterosexual parents as a base assumption. Someone who is extremely supportive of gay rights who is also a rational thinker might be cautious when considering the issue of adoption by homosexuals. Why be cautious? Because it is necessary to take reasonable measures to guarantee the children will be raised appropriately. It is a human right of the children. In American society we place an especially high value on protecting the rights of people who cannot defend themselves, including children and the disenfranchised. Yes, homosexuals are a disenfranchised group as well, but there are homosexuals who serve openly in Congress. It's not quite on the same level as children, who do not yet have the ability to speak English.

I'm not up to date on the literature regarding child development. It may be that there are studies that suggest that homosexual families are no different than heterosexual families in terms of impact on the child. I'm just throwing this argument out there because it is one of the few non-homophobic arguments against homosexual adoption that I know of. I don't personally have an opinion on this issue because I'm not qualified.
