johnl··on Ask HN: Why is the last 10% always so hard?
If it is user oriented, I would release the project and make sure you have a feedback loop to see how the project is being used by the end users. You are finished when they are happily using your project, you usually don't get to decide for them. If the project is presentation oriented, or if you only think you get one shot, then I usually step away, come back, make a punch list, and complete the project by completing the punch list.
johnl··on Can you be too incompetent to understand just how incompetent you are?
You can say that about smart people too. It is just hard to jump outside the framework of your own education and experiences and come to a conclusion that conflicts with everything you see as being right. He should have validated his hypothesis by backing into his conclusion using several independent methods and not relying on just one.
johnl··on Hedging
An interesting read. Hedging: A transfer of a portion of a position's risk to another party. Risk can be transferred, it can not be removed.
johnl··on Critique My First Start-up? (Not yet public)
I would recommend some backtesting results so people can see what they are getting into.
johnl··on Ask HN: If someone else is "doing it", is that a reason not to compete?
There are lots and lots of hotels in any city that serve different niches of the market. Not just one. Some marketing analysis might reveal niches that can be exploited cheaply by you.
johnl··on Google Spreadsheets: Game of Life
Ask you a question: OK. Why doesn't Google develop a database that is somewhere between Excel and SQL. Instead of Relational or cell and column oriented, make it list and tag oriented that sits behind the web page. The database would help consolidate a lot of stuff I now see hardcoded. The idea would be to take a Posterous like site, add the list and tag database and come up with a Facebook type of web page. The second phase would be to consolidate that data over the web to make that summarized, rankable and searchable.
johnl··on Posterous takes on Tumblr
I wonder what Posterous's arguments were for going for the direct attack route instead of an offer to purchase or merge? You can get bigger quicker by purchasing competitors than by swiping their clients I would think.
johnl··on Ask HN: How to become a millionaire in 3 years?
I would not even think business, takes longer. Think infomercial. For example: That star wars sword thingy was just a flash light on the end of a plastic tube and made the guy a million so I heard.
johnl··on Stock prediction using Weather, Twitter, News & Stock sites...
Measuring the psychology of the markets using web seems to be an interesting idea. This a better shot then most I have seen. Next step is to see if each stock's results are leading or lagging and over what time period.
johnl··on The Pattern-Seeking Fallacy
My summary of the article would be: Relying on the statistics of a distribution works but relying on a optimization of the same distribution doesn't work.
johnl··on Linden Lab laying off 30% of staff, Second Life to be browser-based in future
Or maybe its the ipodization of the web where you no longer hop from web site to web site but suck the apps to your browser as you like.
johnl··on As the Sun Awakens, NASA Keeps a Wary Eye on Space Weather
Here are some charts on the subject. http://www.financialcyclesweekly.com/public/530.cfm?sd=2 The charts are interesting but not sure about the financial links. They do seem to affect weather patterns which in turn affect crop yields.
johnl··on VC investments in education
Sound like you need 2 apps, one: the teacher's assistant app that the kid works with and a second app that monitor's the analytics of the students progress real time so instead of working one on one with the kid you can work with multiple kids with different hours and with different study paces all at the same time. Teachers and parents can review the progress from a overview level and direct accordingly.
johnl··on VC investments in education
The parents are the ones that pay you so maybe that is where the deal can be made. Make it so the parents can oversee the kid's progress without actually knowing the answers or doing any work. A cheaper tutor.
johnl··on Save My Life - help a fellow HN'er
Out of curiosity, when you last had the flu, did your muscle aches go away and your head fell clear right after your fever broke?
johnl··on VC investments in education
My thought would be to stay away from the teachers. Quiz the kid to see where they need help and then teach away with loads of feedback and reinforcement.
johnl··on VC investments in education
That's what I was thinking. The markets is there but in front of it there is this very big bureaucracy that you have to deal with. So maybe point the app towards something like homework where the educational bureaucracy doesn't have much control.
johnl··on Google ditches Windows on security concerns
I would agree. Windows has the largest population of non-computer literate people worldwide so hackers get the bigest bang for their buck and windows gets a bad rap. If everyone jumps to another OS so will the security problems.
johnl··on 14 Survival Traits of Successful Entrepreneurs
A good book and a quick read on the same subject is: Deep Survival by Laurence Gonzales.
johnl··on Twitter Bans In-Stream Ads
Making a firm decision like this as to what the Twitter customer wants seems like a bad idea in my opinion. I would have rather have seen Twitter create a preference check box allowing those who want ads to have them, and set 3rd party ad policy for Twitter to share in the revenue. Twitter is far from having a secure source of income so killing instead of controlling early revenue sources doesn't seem like a good idea.
johnl··on Ask PG: Do you think the YC Model could scale to other industries?
Also quickly. Being able to have something up and running and building momentum in 3 months would be as important as cheaply.
johnl··on Ask HN: Do you recognize this approach to programming?
First thing that came to mind was Smalltalk. http://en.wikipedia.org/wiki/Smalltalk. Developed in the 80s but have no idea where it went. .
johnl··on Ask HN: How on earth can I grow an "adult" company?
Being "adult" may not be the problem. You may want to think of the problem as a "niche market" problem. Retail companies that succeed in niche markets do so by branding themselves better than everyone else. You might look for a different "niche" to market like adding hair trimmers, body washes, etc to attract a different clientele and market the higher margin toys as a website afterthought.
johnl··on The Big Game, Zuckerberg and Overplaying your Hand
I like the comparison with poker. Doesn't mean that Facebook is out of the game by a long shot, it does open the space up for some competition. Maybe the companies that helped push FB along should get together and start their own?
johnl··on Six companies, including owners of Sam Adams, traded today at $0.00 per share
My guess is that the algorithms do well within say one standard deviation range but beyond that the computers step away. Once the computer volume drops, markets get thin and "Market Orders" produce the results you see. You see bad fills quite a bit in penny stocks but never in these large volume stocks.
johnl··on Citigroup may have caused 1000 point drop, probing rumor of erroneous trade
Accenture went from 41 to 0.04, back to 41 on twice the previous day's volume. I guess once the computers stop, the markets get thin really fast.
johnl··on First symptoms of psychosis evident in 12-year-olds
Seems a little early to start pigeonholing kids for that type of stuff. I would rather pick it up from grades and such. And put yourself in an environment your not used to and most everyone will see and hear things that aren't there too.
johnl··on Obama advises caution in use of Facebook
I thought the issue wasn't "Obama is right that you have to watch out what personal information" you show per the comment but that Facebook is the culprit in exposing what information is public. A consistent policy from Facebook would go a longer way than getting the government involved to "police" the internet.
johnl··on We Have Met the Enemy and He Is PowerPoint
It's not so funny when you think that everyone depicted in the diagram is heavily armed. McChrystal is right though, rearrange the dependencies into a more controllable bureaucracy (like writing a program) and you will have a better chance of success.
johnl··on How to Keep Crappy Programmers
The article might add that having lots of department meetings is also a excellent way to keep crappy programmers.
