padwiki··on RubyMine 4 is Here to Make You Feel the Productivity
Nice to see you found decent customer service. My experience talking with them about educational licenses was a textbook example of how not to land new clients. Very disappointing.
padwiki··on Ask HN: Can I help you be more awesome today? (No strings.)
Ok, here's a specific question I've been mulling over for a little while. We're launching our college in about 10 days and have been discussing the best way for prospective students to try out the system.

We have limited server resources (limited as in we probably shouldn't let in more than 1000 guests at once until we know our true capacity) but want to show the system off to as many people as possible. Questions we need to answer:

Should we require any personal information in order to try the system? If so, should we verify that information before signing in.

If we don't collect personal information up front, is it worth bugging them when their session is over to be put on a mailing list?

How should we handle limiting simultaneous users? Options:

1. Allow unlimited user signups but only allow logon if total active sessions less than our max.

2. Only allow signups if there is space in the system, logon is immediate.

3. No signup at all, just rotate through a fixed number of guest accounts for preview. If full, no entry allowed, but can be put on mailing list when slot opens up.

4. ?????

5. Profit?

Our target audience is proficient programmers and our primary system focus is speed, simplicity and usability.

Any input is very appreciated.

I think the pricing may be off a bit, but this is an excellent idea for a couple of reasons.

First, the super-memo algorithm has been proven effective for more than 20 years, and can be very effective for building a wide base of programming knowledge.

Second, much of learning has to do with cognitive load. Having a wider knowledge of the capabilities of a language can reduce the cognitive load of solving individual problems. Compare the ease of solving fizzbuzz with modulo vs a home brewed solution. If the system can assist in building a base of concepts then it might make individual tasks easier.

padwiki··on Khan Academy: It’s Different This Time
If it helps, this is exactly what our school is built around. Every class we create is available both in a degree track as well as ala-carte to students exactly like yourself. You have the same professor and t/a support, grading and evaluation. You also have the same access to the resources in our learning system. We are tuition only (no fees) so we even charge the same amount as the degree seeking students ($100/credit, $400-$500 per class, $5k for masters). And, if you decide to go through admissions and seek a degree, any courses you take would apply towards that degree.

The only real difference between in degree and ala-carte is that degree seeking students will have more options for how to pay for their education. Once we are accredited, a vast array of financing becomes available for students pursuing a degree. Some are good (grants, scholarships, state subsidies) some are not (Student loans), but having options for our students helps a great deal. We structured our program this way because we come from your exact position: why can't I take the classes I want without all the BS?

I think the reason more schools don't do this is that it would expose the true cost of these classes, which at institutions like Stanford or MIT can easily exceed $5,000 per class. Actually, after fees, housing and books, $10k is closer to accurate. The market for $5k classes is not huge, and without putting everything on a gigantic student loan credit card, few rational consumers would pay the price.

padwiki··on The Amazing Power of Deflationary Economics for Startups
This is a fantastic article, and really hit home with our project. The rules of deflationary economics has become common knowledge in most product and service industries, but in my industry (higher education), the opposite seems to be true. Every single legitimate competitor raises prices year after year, much faster than the rate of inflation. The few that don't (Khan, MITx, Stanford, Udemy, etc...) do so by scaling back the user experience, reducing difficulty and removing credentialing. This means the value proposition to the student, even at no cost, will not match the entrenched system. There is a market for this new class of product, but it is defining a new market rather than competing in the existing one.

I actually think the reason more companies don't follow the strategy he outlines is that it is just too damn tempting to take the quick cash. For example, the current market value of our product is in the $500-$2500 per credit hour ($2,000-$10,000 per class) range. We could charge in this range and be extremely profitable. Instead, we price our classes at $100 per credit hour, pay our professors a much higher percentage and choose to take a slimmer margin. In classical "next quarter" business terms, this is a very bad business decision. Doing so, however, opens up a number of opportunities that our competitors can't exploit. For instance:

We had to develop technology and workflow that dropped the cost of high quality interactive content down from $10,000 per hour (or more) to around $120 per hour. Now that we have that option, we can scale our course offerings extremely rapidly while keeping costs at a minimum.

Being able to offer a bachelors degree for less than $10k (masters less than half that) gives us options for creative financing of education that again, our much higher priced competition just don't have. Student loans no longer become necessary, even without subsidies. State and federal subsidies could easily cover the entire cost of tuition (California currently spends more than $12,000 per student per year just at the community college level). Also, as our first program is CS/SE, there are many companies with a vested interest in increasing the number of graduates and having access after they graduate. The point is, we expect to be able to offer most of our programs at no cost to the student within a few years.

Since our largest cost saving was in not having any buildings, we are not limited by a physical infrastructure when it comes to scaling. We also designed our system to benefit from having more students, which means the quality of our program will increase as we grow...something that can't be said about many physical campuses.

TL:DR; Higher education is about to enter the tornado.

padwiki··on Ask HN: What to do with the ability to fly for free?
Fair enough. I feel the same way about my mySpace page and AOL account. So hard to let go sometimes :)
padwiki··on Ask HN: What to do with the ability to fly for free?
Here's a suggestion; don't ask about creative ways to use airplanes with the user name "killa911".
padwiki··on Poll: Would you pay a developer who is 3x as good as average, 3x the salary?
This is very illuminating; thank you for sharing your thoughts on the subject. I can see where you are coming from in regards to diversification, although I take a slightly different angle. If I'm taking 75% of the salary I would in a fortune 500 gig, I already consider myself 3/4s diversified. Plus, I can always work 4 startups in 4 years and just take the first cliff worth of stock, which diversifies even more. Granted, it's no mutual fund, but it's not "I'm locked in to one company for 1/10 of my life and if they go under I'm bankrupt". It's a little less money for as long as I choose to work there in exchange for a potential return on investment.

If I were go back and look for an equity heavy gig, and I don't plan to, I would look at the entire process as an early stage investor. No, I can't invest in 10 or 20 different companies, but I can be selective and increase my odds. Actually, anyone with my current skillset could walk into any startup in the valley and start working the next day. That is something few, if any, angels could do.

padwiki··on Poll: Would you pay a developer who is 3x as good as average, 3x the salary?
Let me put it another way. Let's say you were flush with cash for some reason. Would you ever invest in an early stage or startup company? Would you ever invest in any company?

Or, do you believe it is impossible to know, or at least approximate odds of, any company's chance of success?

Let me put it to you yet another way. Which is more likely to go out of business in the next two years, blockbuster or BP? If you say blockbuster, why?

padwiki··on Ask HN: Want To Become Freelance Web Developer/Designer
Scratch all of the above. I really don't want to sound like a dick here, but there is one skill that will help you immensely in your career. Try googling something before asking senior team members.

Also, and this is just nit-picky, but try to use complete words in your correspondence.

padwiki··on Poll: Would you pay a developer who is 3x as good as average, 3x the salary?
So, if you were an early stage Google or Apple employee you would take salary over stock?
padwiki··on Poll: Would you pay a developer who is 3x as good as average, 3x the salary?
Yes, and here's why. it's not about project productivity, it's about building your company. "A" players hire "A" players. "B" player hire "C" players. "C" Players don't want to look bad so they hire "F" players.

That being said, I wouldn't pay them 3x in straight salary. Equity and profit sharing is a better motivator.

padwiki··on Can you help me with my thesis research? (
Glad to help out. Took about 7 minutes to fill out, for those interested in contributing.
padwiki··on Can these Simple Cartoons Redesign Education?
I've watched a few of them and no, they can't. They can be condescending and long winded though...so there's that.
padwiki··on Ask HN: Want To Become Freelance Web Developer/Designer
Ok, that adds quite a bit of clarity. From your first post it was unclear where you were starting from.

So, the money and demand for junior developers tends to lean towards front end or full stack devs. If you want to work for a startup, learn rails or django really well and then learn how to build client side apps in JavaScript (communicating through AJAX). Use frameworks everywhere you can (jQuery is the de facto standard now). Learn everything you can about HTML5, Canvas, the new Audio and Video tags and CSS3. Keep pushing forward on design, but remember, less is more in the new era of web aesthetic.

If you want to work for larger companies, learn two of the most common frameworks built on Java and make sure you are very comfortable gluing libraries together. You can also learn the same front end skills, but the chances of being able to do anything full stack are slim to none.

Books and videos? Too many to list really. Code complete, gang of four design patterns and mythical man month are pretty common. Don't make me think is also excellent.

Pay rates? Depends very much on location. Pay rates for the exact same job might be $25/hr in Iowa and $100/hr in Mountain View. In general, if you are good and want to be challenged, come out to the Valley and don't accept anything less than $50/hr to start. Salary: with a couple years experience you should be able to easily crack six figures.

A lot of it depends on your exact job, the support network you have and how much cash your business takes to get running.

If you are a programmer or other highly employable type, my advice is to form an s-corp, get an hourly contract that will pay you 1099 and then hire people to build the product you want. Your take home pay may end up being even higher than it was before, even after paying your contractors. And, you won't have a runway to worry about.

Then, focus on cash flow ASAP. If you can get enough revenue to support yourself, then quit and dedicate yourself full time to scaling.

Alternatively, if you can reduce your expenses very low and don't make enough to pay others to build your product for you, it might be better to quit and build it out yourself.

padwiki··on Ask HN: Want To Become Freelance Web Developer/Designer
Couple questions back:

1. Can you program at all right now? If so, what languages and how much experience in each?

2. How stubborn are you? How do you react to stressful and frustrating situations? Do you get excited by fixing difficult problems or do you get frustrated and give up?

3. How are your design skills? Any graphic design or illustration background?

4. Have you self-taught any other skills in the past? If so, what? How was that experience for you?

5. Why web programming? Is it only the extra side money?

padwiki··on Ask HN - Would a start up take me seriously?
Ok, what we see in the valley are two types of recent graduates. We see "curriculum only" graduates who can barely use an IDE and can't code their way out of a paper bag (usually without real internships). These graduates require 2-3 years of experience before you can trust them with any level of complexity and are not really hire-able unless the startup is very desperate. It's very easy to filter out these candidates but they also (saldy) make up the bulk of the applicants.

Then, there are the geek's geeks (you). We love candidates like you. You put in long hours for usually much less pay than a senior engineer and don't know enough to realize that free pizza isn't really a benefit. You will not have any trouble securing offers after you graduate.

Now, there are some things you can do to make yourself even more hire-able than you already are.

First off, years of real world experience matters more or less depending on the technologies you use. If you are very good in a hot skillset you can name your price and choose your company regardless of experience, degrees, body odor, etc... Right now, the hottest language in your background, by quite a bit, is Javascript. Good UI people, and specifically good JS guys, are extremely hard to find right now. If you add in some solid backend skills (you already have Java, which is good, but Rails or Django might be even better) you are starting to look like the perfect candidate for any startup.

padwiki··on A different way to pay tuition
It's interesting that the UC administrators think that the "paying for" is the part that needs to be addressed, not the base cost to begin with.
padwiki··on Ask HN: What should I spend my $150 monthly education expense on?
Honestly, in your budget, I think your best bet is going to be focusing on building your library. You can get the same benefit from conferences by snagging the webcasts and papers online. Colleges and Universities (other than mine, and our backend courses probably won't be ready for another 6 months or so) don't really teach Python, and the Java they teach is academic. Plus, you are looking at $500-$1000 a credit for anything decent you might find.

Certs are nice for networking and security, but for application development, experience counts for way more.

So, as much as it kind of sucks, loading up on the reading material is where I would spend my budget.

padwiki··on Ask HN: I'm an experienced backend developer, but clueless about GUI app dev.
15 year full stack developer here with at least 8 of those years doing GUI stuff. Over the years, the two biggest things that helped boost my skills were:

1) Write a game.

It may sound cheesy, but it gives you a frame of reference to work from. Most people have played enough games to know when the interaction feels right or wrong. If, like me, you decide to write a game in the browser, it will also teach you many, many things about working with the DOM, optimizing for performance, managing memory, etc... Plus, it looks freaking fantastic on the resume. I recommend a 2D side scroller (I did Mario in JS) or top down (zelda would be cool). Be careful of anything with large numbers of moving things on the stage at once (contra, for example). Optimization can kill you with those.

2) Write in a framework.

For instance, if you write a iPhone app, the obj-c based framework tends to guide you towards a usable, responsive app. Same thing with Rails and QT. You can also find scaffolding for all of the above that will lay down the groundwork for you to expand on.

padwiki··on Ask HN: What should I spend my $150 monthly education expense on?
What technologies/languages do you want to focus on?
padwiki··on Must see areas/things to do in San Francisco for hackers?
I third Mountain View, and the computer history museum. Also, while you are there, check out Hacker Dojo. If you need a lift anywhere I live a block from the train station in MV and never mind a quick siteseeing tour.

In the city, check out Tech Shop if you have any maker inclinations.

padwiki··on What real-world events would it be useful to receive notifications about?
I would like to know about things that the powers that be specifically don't want me to know about. Laws that are being slipped through under the cover of night. Any changes to civil or human rights issues. Funding connections to politicians. Abuses of power.

Basically, a transparency module. And yes, I know this is what newspapers used to do, and some blogs attempt to. The signal to noise just isn't great and delivery is not very directed.

padwiki··on Ask HN: Will crowd-source-coding work?
I would suggest being more direct in stating exactly what the site is and especially how it can benefit the user. Right now it has a "this is a thing I built" kind of vibe, which is not great for driving signups.

Find out what the real problem you are solving is and really focus saying exactly how you solve it.

padwiki··on Ask HN: Prepping for a Javascript Interview
Sorry, should have been more specific. they might ask you if and how JS handles general threading concepts. The correct answer, as you alluded to, is that aside from web workers, JS is not multi-threaded. You could then talk about the challenges of creating complex applications in an asynchronous event driven structure.

In other words, as an interviewer I would ask about threading to filter out the "huh?" type applicants and give them a chance to talk about some of the nuances of working with JS.

padwiki··on Ask HN: Prepping for a Javascript Interview
Closures, closures, closures. Also, know how JS handles floating point arithmetic, type coercion, threading and the difference between async and sync.
