dj_axl··on Streak.com (YC S11) Takes On Salesforce With A Simple CRM For Gmail
> Streak should actually be something like Thunderbird extension with RDBMS running in background

The most popular email client is Outlook with iOS devices in second place (as of June 2011). Although if you combine Hotmail + Yahoo Mail + GMail the total marketshare beats Outlook.

dj_axl··on GoFlow: a DIY tDCS brain-boosting kit
Beware, there is a 2 in 933 chance of developing a severe skin rash reaction, and the FDA has rejected modafinil for this reason. From Wikipedia:

"The FDA advisory committee voted 12 to 1 against approval, citing concerns about a number of reported cases of skin rash reactions in a trial that included 933 patients on modafinil, including two severe cases which appeared to be "definite" erythema multiforme or Stevens–Johnson syndrome. One of the two severe cases involved hospitalization."

dj_axl··on What if doing your best -- at what you're best at -- isn't enough?
> refuse to try again

The ways I've heard it are, "never let it happen again" and "learn from your mistakes", in other words don't make the same mistake again. Sure one refuses to try the exact same strategy again... because it didn't work the first time. That doesn't mean one stops trying altogether. Refactor/pivot and give it another go.

dj_axl··on Why the cloud isn't for your startup
> our customers paid for the growth

This is key. You might need to add another word to cloud... something like "cloud redundancy" or "cloud backup" or "distributed cloud"... if customers will pay for it, sell it.

dj_axl··on There is no point to distributing music in 24-bit/192kHz format.
> The article's about distribution, not recording. I don't think anybody disputes the usefulness of higher sampling rates when recording.

Didn't read the article, so commenting out of context, however it needs to be said that in sample-based music genres the distributed music gets used as if it were a recording. Maybe then it could be argued that higher sampling/bit rates should be available, if only for those who are sampling.

dj_axl··on Lessons from Moneyball
> It was not made clear to me why the protagonist made the choice he made.

He was rejecting the hoity-toity New Englanders and their fancy tea served in fancy porcelain teacups. However yes I'd agree that wasn't sufficient explanation. Maybe there are more details in the book?

dj_axl··on Electric brain boosting
I can't find the specific article I was looking for, maybe it's more urban legend than fact, but supposedly chess players burn just as many calories per hour as athletes. In the top results on google you'll find comparisons of chess players to football players, and chess grand masters to olympic swimmer Michael Phelps. Somewhere in here is material for an infomercial sure... play our specially designed MMORPG and the calories will magically melt away!

dj_axl··on The Golden Age of the Developer
> Today is the golden age? Not to people who’ve been doing this for a few years.

Things seem to have turned on a dime. Around the subprime mortgage crisis (Lehman Brothers declared bankruptcy in September 2008) things were looking dire. However around now (December 2011) things are looking much better. Experienced devs in New York / Seattle / Silicon Valley / Los Angeles are making more than you think. I've even heard that devs fresh out of school in Boston can make $140K.

dj_axl··on Why big companies fail to keep talent
> If you stay at a company, they will give you some fixed pay increase, perhaps tied to your annual review. After a few years, your pay could get seriously out of whack with the market.

This. In my experience, especially applies to H1-B employees or any employees who are perceived to be unlikely to leave. One downside is that, lowering the average salary of all employees makes hiring new employees (at current market rates) difficult. Thus begins (or continues) the downward spiral.

dj_axl··on Startups say the darndest things
"We've got early traction" = Our investors has made sure their other portfolio companies use our product.

Would you rather work for a company where the investors can't even convince their portfolio companies to use the product? Sure I get the humor. Maybe a solution would be to actually name one of the (hopefully big/famous) companies that use the product, instead of being vague. "Some great places have employed our solution! But we can't reveal any of their names!" Um. Yeah.

dj_axl··on Why programmers are not paid in proportion to their productivity (2009)
> My biggest problem with the 10x productivity claims is that it ignores the most relevant difference. The best programmers don't do the same things faster, they do completely different things.

I thought the 10x productivity claim was originally from a study of comp sci students working on some algorithm (maybe compression algorithm) homework. In which case the "I think I've seen this before" example from the article probably factors in most.

dj_axl··on Build business apps in .NET - not HTML or JavaScript
Is it just me or is this blog post not clear on what the definition of "business app" is? If it's for internal use, fine, whatever. If it's for enterprise application for millions of users, build the backend in C#/Java/Python/Ruby/Erlang/yourlanguagehere and build the frontend in something crossplatform like HTML/JS or Flash/Air. If you plan developing apps as a business, look at the SaaS/SaaP/cloud model.
dj_axl··on Why Science Majors Change Their Minds (It’s Just So Darn Hard)
The tl;dr I got was that high school didn't adequately prepare students for college. Just to have h.s. kids enthusiastic (as someone else mentions in the comments here, high on dopamine) they make things entertaining/easy. While some may argue that college level should have more real world applications, I would argue that high school level should have more hard challenges that fail half the class. Maybe have a class that doesn't count towards your GPA that is super-challenging.
dj_axl··on Outsourcing Startups
> or more often they just not technical enough to judge the technical quality or the timeliness of what they are paying for.

Anecdotally, this is the case. I've heard of or worked for three 400+ person companies that outsourced. Two of these companies had metrics/standards where they could actually measure code/work quality. One of these companies did not. The two that were able to judge were not happy with outsourcing and stopped outsourcing after a 1-2 year trial period. The one that seemed to only be aware of the short-term cost savings without being aware of the long-term code debt, they were perfectly happy. Different strokes for different folks, whatever floats your boat.

dj_axl··on How the R-project is taking over statistical analysis software
Anecdotally, NumPy (Python) has some traction. Similarly they don't consider SQL libraries. And I'm sure there are statistical analysis libraries for Java. According to the bar chart below R is mentioned by 45%, SQL by 32%, Python by 25%, Java by 24%. This seems a more reasonable comparison to me than the graphs earlier (higher up) in the post.

dj_axl··on Lytro cameras are ready for preorder.
> The Lytro camera captures all possible focus settings.

There's a reason photographers prefer certain lenses for sharpness, which can be measured in lp/mm and I wonder how the Lytro compares there. The f/2 glass is probably decent for portraits and exhibits high levels of diffraction when shooting landscape images at f/22. If light field photography solves these problems then that would be very interesting to me. For $399 and shooting at 3-4 megapixels now, it will be a few years before this reaches the 18+ megapixel pro-am level and deals with pro-am criticism.

dj_axl··on Are jobs obsolete?
> Why pay 3/4 of the population to work 40 hours a week when we could pay all of them to work 30 (then 20, then 10)?

Because corporations want to pay 60% of the population to work 50 hours a week on salary. This is why everyone should be hourly. That's the first step. Then, yeah sure, hourly with overtime pay for anyone working more than 30 hours a week.

dj_axl··on After working at a startup, I'll never work at a big company again
> No. Wont be working at a large company again.

Agreed, although in my case it's more "Will be checking reviews on Glassdoor.com before working at any company, large or small." Unfortunately the "players" have infiltrated Glassdoor as well and you have to suss out the "real" reviews from the "player" reviews.

dj_axl··on How To Become A Better Programmer By Not Programming
This is missing what I will quote from another post above "If they really believe in something they will work on it and become better." If you peak at something this makes you good. If you work ard at something this makes you good. If you peak at something and work on it and become better, this makes you great. Evolving gradually but steadily might increase one's belief that hard work is rewarded, however you will never become great, merely good.
dj_axl··on In response to This*: Stop letting engineers get away with social ineptitude
> laziness and a holier-than-thou attitude

A short explanation might be, socially skilled people are slow (lazy) to understand anything technical and are impatient (holier-than-thou) with unskilled people. Technically skilled people are slow (lazy) to understand anything social/political and are impatient (holier-than-thou) with unskilled people. I think it's possible, though slow, to teach any skill to anyone. To really fix the problem, maybe start by convincing companies that teaching skills outside your area of expertise is worthwhile. I can get technical training paid for by my company. Social/managerial training, not so much. Likewise project managers can't get reimbursed for technical training. The assumption seems to be "Oh well they don't really need it and what they do need they'll pick up on the job or on their own time."

dj_axl··on DNA
Joking aside, one of the places I worked tried to hire an ex-Google CTO, He basically wanted to be the CTO and then have 20-30 developers reporting directly to him. That to me is flat. And that did not fly well with the business people. "No! We must have 3-4 subordinates max under each role, reporting up the hierarchy!" I imagine you can't grow to a large size without hierarchy, but with 20-30 people it is possible to be flat.
dj_axl··on Revolutionary "Light Field" camera tech - shoot-first, focus-later
According to Wikipedia this is called "focus stacking", combining depths of field to create a larger depth of field. The page lists a number of apps/plugins that blend photos to create this effect:

dj_axl··on LNKD IPO opens huge at $83
During the first 30 days after an IPO, the underwriters are not allowed to lend shares for short sale. Additionally, number of shares are limited. The entire float is not available on the first day of trading. So today, it is probably impossible to short. 30 days from now, it should be available to short.

dj_axl··on Anti-Facebook Startup Diaspora Promises to "Go Faster"
PogoPlug (http://www.pogoplug.com/) and Dropbox (https://www.dropbox.com/) are more popular than Diaspora, methinks. Maybe they could rename themselves to "Diaspora Cloud" or similar.
