Lol: "On my first day, at the freshman picnic, I heard that 50% of us would end up in the bottom half of our class." - I was reminded of this when I failed my first test in college!

Re: Learning from 2014 Security Hacks

Related to this, there's also that recent court decision, saying that your fingerprint is not covered by the 5th amendment, unlike passwords...here's a link:

I use 1Password, plus MFA on most sites where it's supported. IMHO everyone should be at least using something like 1Password or LastPass...

Agree with Trevor - it's disappointing this took so long to get to the top of the list, but I'm glad it's happening. I would also suggest thinking through password resets (https://www.hover.com/signi... - if someone compromised the email address I use here, they could reset my password, and then they could compromise every domain I have here (including email on those domains).

So is the SIGQUIT behavior different now? It wasn't clear from the above. If so, is there a new recommendation to "tell workers to complete their current job and then quit"? I could use a long-ish RESQUE_TERM_TIMEOUT (like 10 minutes), but that's not exactly the behavior I'd like...

Best comment ever. I was having weird problems that didn't really point to this at all, but this fixed everything I was running into. Thanks Henrik!

Re: You Need a Trading Journal

You might take a look at Tradervue (http://www.tradervue.com) - it makes it easy to keep a journal, and provides a bunch of analysis tools...

Re: Overview of Balance Sheet and Statement of Cash Flows

Just a thought...perhaps you could have the company operate for a week, and have some expenses and income, and show how that gets reflected in the above...

edit: and perhaps also buy some equipment, like computers and such?

Re: Day Trading Journal

greinacker — Thu, 18 Aug 2011 13:17:48 -0000

This is good advice - I wholeheartedly agree that everyone should keep a trading journal. I found my journal to be the most valuable learning tool I have.

I'm a touch biased :-), but it's worth taking a look at Tradervue (http://www.tradervue.com). It's a new (free) web app that launched a couple of weeks ago, designed specifically for helping traders keep their trading journal, and automating some of the busy work that goes into it. And once you have your data in there, you can see analysis of what's working and what isn't, and even share some of your trades with the community if you wish.

Re: Why My Next Airbnb Guest Will Burn Down My Building Leigh Drogen

greinacker — Mon, 01 Aug 2011 19:38:24 -0000

Heh. Well, just make sure it doesn't burn down between August 1-14, which seems to be a bizarre hole where nothing is covered. From their blog:

"Starting August 15th, [...] personal property will be covered for loss or damage due to vandalism or theft caused by an Airbnb guest up to $50,000 with our Airbnb Guarantee. [...] This program will also apply retroactively to any hosts who may have reported such property damage prior to August 1, 2011."

Bummer if you're on Aug 5, I guess!

Re: Should You Paper Trade?

greinacker — Wed, 27 Jul 2011 11:51:16 -0000

Somewhat related, for those who play poker, you know that it's a COMPLETELY different game when you're playing for money you care about. If you're playing for free, or playing for some amount that's immaterial to you ($5?), it's one game. When you're playing for something that's significant to you (or the potential winnings are significant), it's a whole different game.

I don't have much more to add to the great comments here - other than to mention that IMHO paper trading is invaluable when learning to trade something like options, where it's not always obvious at first what your position value will be for various moves in price or volatility. Thinkorswim's platform is great for modeling this!

Re: Learning the Right Lessons from the Amazon Outage

greinacker — Mon, 25 Apr 2011 20:44:07 -0000

Good post. On your lesson #2 about Amazon not to be trusted...I agree with you. However, it certainly wouldn't hurt for them to be a little more transparent about how their availability zones within a region are constructed, how they relate to each other, and how they deal with a complete failure of one AZ...hopefully something positive will come out of the post-mortem they do.

Re: Market Primer, 5-9 Investing With Options

greinacker — Mon, 10 May 2010 12:12:53 -0000

Ok. It was the dividing by 2 that threw me - my range was 2x the size of yours, so I was wondering if there was something I was missing.

Re: Market Primer, 5-9 Investing With Options

greinacker — Sun, 09 May 2010 16:13:12 -0000

Steve, you said in the video (and your spreadsheet agreed with what you said) that VIX / sqrt(252) would be "2 times the expected daily range." But as I understand it, taking the expected volatility (in this case, the vix) and dividing by sqrt(# periods) should give you the stdev of expected price move for the period. And we know that price should remain within a +/- 1 stdev range about 68% of the time. So...I believe the expected daily range should actually be +/- $28, or 1082 to 1138, rather than the range your spreadsheet has of 1096-1125. Similarly true for the expected monthly move. So...the "2 times" thing you mentioned is throwing everything off, I think. No?

Hmm! I found a (painful) way to view the page source from the iPad, so i have a workaround for when the links are missing. Let me know though if there is anything i can do to help you figure out how to get the links inserted automatically in your workflow! Happy to help if I can.
