cloudkj··on Georgia Tech adapts to increased cheating among CS students
Well, the alternative isn't that great either. At Berkeley, many undergrad business students had the option of taking an intro CS course (symbolic programming with Scheme; awesome course) or an interdisciplinary course called "introduction to computers." The latter was pretty much a joke; I remember helping some business friends with their projects, and it involved making HTML pages with frames and figuring out how to FTP files onto some servers. Pretty lackluster.

From the looks of the teaser, looks like it could be similar to Little Big Planet, which has been a hit on the PS3.
cloudkj··on Ask HN: Steady 4-5% on $5 million?
I think the best approach is to read up on asset allocation (other posters have discussed various books and resources), recognize the amount of risk you're willing to take on depending on your timeline, and make a plan for periodic allocations starting now. If you properly allocate your capital amongst different asset classes like stocks, bonds, real estate, commodities, and cash equivalents, you'll probably find a sweet spot for good returns balanced with reduced risk. The plethora of ETFs and index funds out there these days will definitely help with making this simple.

Another consideration is to become a direct investor in some sound businesses. Start looking through your networks. Being an angel investor may not be your cup of tea, but maybe you have friends or families that are running great small businesses. If you have good confidence in a business, there's no reason not to invest. There's a personal connection there, and you're likely to get the boost of great returns as well.

cloudkj··on Ask HN: Steady 4-5% on $5 million?
I've read the books you listed, and whole heartedly agree with the Graham/Dodd/Buffet crowds with respect to fundamental analysis. However, I don't think this philosophy is mutually exclusive with the Efficient Market Hypothesis. I personally believe in a loose form of EMH, since it actually makes intuitive sense to me. A loose form doesn't mean that investors are SOL in terms of finding good investments; they just need to work much harder (doing all the things you outlined: reading and learning, constantly) to build a high margin of safety and refrain from speculating on high risk securities.

To add to your insightful comments, I'd also recommend subscribing to The Economist to get excellent worldly news about business, finance, and economics.

cloudkj··on The best running shoe may be nature's own
I've always run with toe first, even though I don't go barefoot. It wasn't until I finished the book "Born to Run" that I realized so many people run with heel first. It just looks non-intuitive and inefficient. The most straightforward transition from a walk to a sprint is to explode on your toes. I really don't understand the heel first running style.

For most field sports athletes, I think it's a pretty natural form as well. For any sport requiring pivoting, cutting, and rotating (soccer, basketball, football, etc) explosiveness is key. I can't think of any activity where heel first running would work, except for really light jogging or power walking.

The high incidence of knee (or other) injuries in some sports isn't really related to running form either. Most of them are a result of trauma, such as landing awkwardly or physical contact. Toe first versus heel first doesn't really matter there, except for the stronger muscles that the former form may build. Running toe first will reduce the chance of injury from persistent strain put on the lower body as a result of long-form running, since it happens repeatedly over a long period of time.

I've considered Vibrams as well, but have been holding off due to the look. You can also try the Nike Free line, which were made with the barefoot running idea in mind. Those have been around for a few years.
cloudkj··on Getting into a PhD program with a low GPA
Tangentially, how do you get into a PhD program without any academic letters of recommendation (if, for example, you've been working in industry for a few years)?

This article claims that the income limits for contributing to an Roth IRA has been removed for 2010. I was under the impression that the limit was removed for _converting_ a traditional IRA to a Roth IRA. See http://www.money-zine.com/Financial-Planning/Retirement/2010...

Effectively, individuals that aren't eligible to contribute to a Roth IRA in 2010 can contribute to a non-deductible traditional IRA, then take advantage of the conversion limit removal for 2010 and convert the traditional IRA directly into a Roth IRA. So, it's not quite as easy as simply contributing to a Roth IRA directly.

cloudkj··on I/o Ventures – A Work/Cafe Incubator Launches In San Francisco
Does anyone know if there's a list of all known startup incubators in the US, and which cities they're in?
cloudkj··on Programmers Should Invest
Agreed. It's also important to point out that the timeframe was in the span of weeks, which is minuscule in the scope of typical investing timeframes.
cloudkj··on Freakonomics: The Quiet Danger of Non-Inflation-Adjusted Stock Returns
The article makes a good point: despite the "masked" non-adjusted returns, you don't really have an alternative to equities over the long haul.

From the linked WSJ article: "All of this might be enough to put investors off stocks entirely, until they consider the long-term alternatives. Measured over the 1978-2008 period, rather than over just one decade, stock performance in real-real terms actually is better than that of just about any other major investment class, Mr. Thornburg found: 4.5% a year. Stocks' ability to keep up with inflation over the very long haul may be their best selling point.

In real-real terms, stocks did better over that period than municipal bonds (2.5% a year), long-term government bonds (2% a year) and corporate bonds (0.2% a year). Real-real home prices were unchanged over those 30 years. Both short-term government bonds and commodities suffered losses. (Mr. Thornburg has experience investing in all these areas, although his mortgage affiliate went bust in last year's housing collapse.)"

For more perspective, check out this timely article: http://www.nytimes.com/2009/12/27/business/27digi.html?ref=b...
cloudkj··on Enough Waiting — It’s Time for Amazon to Buy Netflix
Amazon strategically places its warehouses just outside of the most populated states. Imposing sales tax would be mean they immediately lose a ~10% pricing margin on sales to states like California. That's quite a big impact.

If you look carefully at the way prices are set on some of Amazon's items, they actually set the price at just below the list price + sales tax for some populated state, such as California. So at first glance the price will seem to be higher than a competitor's, but it's actually cheaper since the competitor (i.e. a b&m retailer like Wal-Mart) has to charge sales tax.

Anyone know what Manhattan-based startup incubator he's talking about?
cloudkj··on Ask HN: What magazines do you subscribe to?
I don't subscribe to any, but the ones I read (either in online or print form via other subscribers) are The Economist (global news, finance, business), Technology Review (published by MIT; awesome tech insight), and Wired (just for fun).
cloudkj··on Court: Microsoft violated patent; can't sell Word
Don't get me wrong, I'm all for openness and transparency. But I do believe there needs to be some level of legal rights protection, and that it's a pretty fundamental pillar of our capitalist system.

Out of curiosity, what do you (and others) think of a patent for something like Google's PageRank?

cloudkj··on Court: Microsoft violated patent; can't sell Word
I'd argue that, rather than banning software patents outright, the process by which these patents are approved should be put under high scrutiny and changed. For a lot of large companies, the approach really is similar to throwing everything against the wall and seeing what sticks. Having gone through the process recently, I'm amazed at how easy it is for an engineer to conceive an idea, pitch it to a few paralegals and lawyers, and get it written up to submit to the USPTO. IMHO, there's a big disconnect between the engineering minds that actually come up with legitimate patentable ideas and the IP attorneys that write and file the patents.

Getting rid of software patents altogether is quite extreme. You need a mechanism in place to protect the property rights of individuals and corporations. When there's absolutely no sense of preservation of property - whether it be tangible or intangible - innovation and risk taking are going to suffer.

cloudkj··on Trading Shares in Milliseconds
From what I remember from Greenspan's "Age of Turbulence," he mentioned that he was pleasantly surprised that the markets were able to absorb much of the shock that happened on 9/11. I believe he attributed much of that to flexibility in the markets, which is probably related to the liquidity and efficiency that are provided by, for example, high-volume traders. Greenspan argues for deregulation of such activities since they make the markets so much more flexible, and able to withstand sudden shocks such as 9/11.

Of course, much of that was before the fall '08 crisis, so I don't know how he'd respond to that :)

cloudkj··on Startup Tips from Jay-Z
I find #2 and #3 to be contradictory. Being a "business, man" is what Jay-Z is all about. He's made himself into a brand. Kids buy HP computers simply because he endorses them. That brand and iconic status is quite separate from his "businessman" status as founder of Roc-a-fella, CEO of Def Jam, owner of the 40/40 club, New Jersey Nets, etc. He definitely stays out of the limelight while running his businesses. That would be the being in the "food and beverage" mode. As Jay-Z the rapper, however, he has to take on a gigantic public image. You can't really follow #2 while abiding by #3.

I also wouldn't say 2001 was when Jay-Z was a "young star." He was already incredibly mainstream in the late 90's.

Of course, I understand that this post was more for entertainment value :)

cloudkj··on W3 gets new Look
From the looks of the star html and _border declarations, validation is failing due to the IE-specific hacks :-P
cloudkj··on Using indexes in Rails
In the more common cases, you get indexes on foreign keys for free. For example, using MySQL with InnoDB, declaring a FOREIGN KEY constraint will automatically create an index on the referencing table: http://dev.mysql.com/doc/refman/5.1/en/innodb-foreign-key-co...
cloudkj··on All 32mil RockYou accounts hacked. Passwords were stored in plaintext.
I'm guessing tree5 is talking about "Agile Web Development With Rails," in which the authors do give examples of creating hashed passwords with a unique salt and running a SHA1 digest. The book also talks about preventing plain text passwords from showing up in log files from form submissions.

From what I understand however, AWDWR is only tangentially related to 37signals.

cloudkj··on Pure CSS 3D effect
Cool effect. Creating this type of 3D effect for any arbitrary image, however, is much harder since you need to manually splice out individual images and sprites, compute position coordinates, and generate the various CSS3 styles and DOM elements.

It would be cool if there was some kind of utility/library to help do this.

Also, I'm not quite familiar with all the new features of CSS3. Which CSS3-specific constructs are being used here? Looking at the source, the main things I see are just many hover styles being declared, with specific positions and dimensions.

cloudkj··on Speculation: Intel Will Buy nVIDIA
Intel and NVIDIA generally operate under different philsophies. Intel, of course, adamantly backs the CPU. NVIDIA has for a while been touting the superiority of the GPU and the idea of general purpose GPUs, with projects like CUDA.

Not to mention, NVIDIA is still reeling from the costs of repairing faulty GPUs from last year, coupled with the impact of the recession on demand. They were also facing pricing pressures from AMD, especially at the consumer/enthusiast level. All of this led to fixed costs and cut into margins, which resulted in lower profits in the last several quarters. However, NVIDIA's management has remained resolute with a long-term focus. IMHO, NVIDIA is, at the moment, grossly undervalued. So that $110B vs $8B market cap is a bit misleading.

cloudkj··on Warren Buffett and Bill Gates: Keeping America Great (1 hour CNBC Town Hall)
Buffet's mentor Benjamin Graham also taught at at Columbia. Buffet always speaks of Graham as one of the most influential people in his life.

In fact, I watched a few minutes of the town hall last night, and he mentioned Graham at least 4 or 5 times.
