Cheaper than Ideapaint... Anyone have first hand experience using both?

$/Sqft comparison

Whiteyboard - $75 for 30sqft - $2.5/sqft -http://www.whiteyboard.com/

Ideapaint - $175 for a 50 sqft area - $3.5/sqft...
http://www.amazon.com/IdeaPaint-Sq-Ft-Kit-Whiteboard/dp/B002...

Tileboard (often makes sense for a bootstrappers whiteboard) - $10 for 10 sqft - $1/sqft - http://www.lowes.com/pd_61082-46498-31023248_0__?productId=3...

While these are all cool, we decided to hell with all of these things and that it was worth it to spend $400 on a kickass whiteboard that flips and does tricks and ended up with this http://www.amazon.com/Quick-Ship-Deluxe-Reversible-Markerboa... (paid ~$400 for it). It is awesome - rolls around and flips and we can take it with us to our new office, which is important.

Does anyone know why whiteboards are so damn expensive?

Congrats to whiteyboard, I think it's an awesome problem to tackle!

I had a lot of doubts right before switching from a big dual-screen desktop setup to a 13" mbp for all my development work. So far, I've had zero issues with it. Basically, it never feels like my productiveness is hindered by the screen size.

Given that the 13" air has a better resolution than the mbp, I wouldn't consider it a problem. Of course, it's a matter of opinion and taste. But at least one skeptic was proved wrong very quickly. My next dev machine will probably be a 13" air or equivalent, if my trusty mbp dies.
Here's a foolproof, safe approach to losing weight without any "cardio" exercise. How long it takes to reach your goal depends on how fat you are. You can safely lose at most half your body fat in 120 days, so if you start with 30 lbs of fat and want to get down to 15, it'll take 4 months.

1. Every week, calculate your bodyfat% with a bodyfat scale or via the Navy method (http://www.scientificpsychic.com/fitness/diet.html). It doesn't have to be perfect, just roughly accurate, say, within +/- 5%. Let f[d] be your bodyfat ratio on day d, so if you calculate 30% bodyfat, then f[d] = 0.3. For the rest of the week, assume f[d] remains the same as it did when you measured it at the beginning of the week.

2. Weigh yourself every day. Let w[d] your measured weight on day d, and let w'[d] be the 5-day moving median (that is, w'[d] is the median of w[d-4],w[d-3],w[d-2],w[d-1], and w[d]).

3. Calculate t'[d], your target weight for each day, as t'[d] = w'[d-14] ∙ (1 - 0.08 ∙ f[d-14]). The 0.08 is related to the maximum rate at which fat can be lost without losing lean body mass ([2]). In short, each pound of fat can supply 20 kcal per day, and a pound of fat can hold roughly 3500 kcal. so (1-3480/3500)^14 is about 0.92, which means you can safely lose at most 8% of your body fat in two weeks.

4. Every day, for the first three weeks of your diet (basically, until you become low-carb adapted), eat 90-110 g of carbohydrate. After that, eat 45-55 g of carbohydrate per day.

5. Every day, eat (h-100)-(h-90) g of protein, where h is your height in cm. (This is Kwasniewski's recommended protein requirement based on "due body weight").

6. Every day, get the rest of your calories from high-quality fats. (See [1] below). Start out so that you are eating enough total calories to maintain your weight. You can find this amount by measuring the number of calories you currently eat. Then adjust the number of grams of fat you eat each day so that w'[d] is as low as possible while still keeping w'[d] ≥ t'[d]. Remember to eat 5-6 more g of fat per day starting on week 4 to compensate for the 50 g drop in carbohydrate intake.

7. Track what you eat with a free site like http://cronometer.com (MUCH better than fitday).

8. Do some strength training to maintain your lean body mass. You won't gain lean body mass on this plan, but you should be able to avoid losing too much of it.

My brother worked logistics for a large company that supplied product to WalMart.

Their distribution centers have timeslots for incoming trucks measured in ten-minute increments. You miss your ten-minute window to park the truck, you're locked out until they can find a space to fit you in.

>Thackeray's use of both forms demonstrates. "The alternative to the masculine generic with the longest and most distinguished history in English is the third-person plural pronoun. Recognized writers have used they, them, themselves, and their to refer to singular nouns such as one, a person, an individual, and each since the 1300s."

I don't really think it's an evolution, as much as the mid1800's tendency to over classify and striate things going away.
The Magical Island of Kanren – core.logic Intro Part 1
The purpose of a patent isn't to grant ownership over mixes of things that already exist. The purpose of a patent is to incentivize full disclosure of novel ideas, ideas that otherwise would be locked up as trade secrets, by trading disclosure for time-limited monopolies over those ideas.

The patent system isn't a prize we give to people for innovating. It's one of the ways we pay people to document and publish their inventions.

Irony: Samuel Morse did in fact vigorously patent his inventions.
Tell me about it... sometimes I'm lucky to even have a PO (purchase order) number to put on the invoice, 30 days after I've completed the work with large companies.

The payments department won't even look at the invoice if it's missing that.
So since they are dead, why don't they release the key to that 'insurance' file? This is what I want to see. I can't imagine it would cost them a dime to release that key.

Multi-decade time frame required to complete grad study? If you have a master's degree already then you only need two more years for a Ph.D (in most cases - or at least both of my parents did and I highly doubt they were both abnormally fast).

Are you solely working on the start-up? I would suggest going about your business without the need to incorporate right away. A lot of people waste a lot of time and money incorporating when they have no idea if the product can be built, is desired in the market place, or validated.

My suggestion would be to come to the U.S for your Ph.D (if visa requirements allow you to do so). You will have two years to work on your studies and then also validate your startup idea in the U.S, which may be more friendly in terms of validation and (if you moved to startup hubs) could be useful in terms of incorporating and scaling.

Whatever you decide to do, best of luck!
I don't know about MIT and Stanford, but I went to Caltech, and while there are first-year courses with names like 'Calculus', they are categorically nothing like the first-year courses at UCs or CSUs.

To put things into perspective, there is zero AP credit offered at Caltech. The only way to skip classes is to pass Caltech's own placement exams. I took the first placement exam (after finishing the entire AP math curriculum, as well as the entire math curriculum at the local community college—through linear algebra, diff eqns, and multivariable calc), got a 96% on Caltech's placement exam, and was recommended to take an extra, remedial mathematics course in addition to the regular freshman load to help bring me up to speed.

European Commission Investigating Samsung's Patent Threats Against Apple
"... and that's the reason you have to have a patent lawyer because the language makes no sense. In US it’s technically English but it’s not really English. It’s like using English words but there are different meanings to them. There is a whole different set of rules about what things mean when they do a patent application."

Well guess what - that is not unusual when everyday words migrate into a technical area and the law is such an area. To complain about words having specialist meanings in a specific subject area strikes me as naive.

Thanks so much. Although I am a co-founder of WhiteyBoard, I do have this up all over my place and it works fantastically.

For people that don't want to pay $2.5/sw ft. We also have our original WhiteyBoard products which we created to combat the origial expensive dry erase boards. We thought Paint was an awesome way ato approach whiteboards, so we made a cheaper and better version of that as well. Enjoy!

Isn't it the case when you sympathise with someone one gives them the benefit of doubt --but when one dislikes someone one envisions the worst?

1. Imagine a good friend accused of something (ex. aggr. assault).
2. Imagine a good friend accuses someone of the same thing.

If instead of Assange, the accused were a live Qaddafi, or, say the Dalai Lama, would we not see things a bit differently, in each case, due to bias?

We just don't know. It's all conjecture at this point with he said, she said.

There are a few things at play here.

There's "culture shock" of being comfortable within the high school world where there's a lot of busy work but it's easy to get an A in any class as long as you put in the hours and can memorize a few things, even if you don't honestly understand the material. And then getting tossed in the deep end of hard-science in college where you have to put in enough hours to actually understand the material, not just do the busy work. And you have to be able to learn in class and learn on your own as well, because there's quite a lot of material to go through. For some people this is like going from George Jetson's job to digging ditches, and it's too much to adjust to.

Relatedly, high schools have been doing a piss-poor job of actually instilling mastery of basic skills like math, reading, and writing so a lot of students will come into college at a disadvantage. When you have, realistically, about one or two years (if not more) of remedial education that you need to get through before you're able to grapple with the actual college level material then college because a lot more of a slog (and potentially a very much more expensive slog) than it might be otherwise. If you don't have calculus, trig, and technical critical reading and writing skills nailed by the time you start tackling chemistry, physics, biology, math, etc. in college you will be at a severe disadvantage.

And finally, as others have pointed out there's the grade inflation differential. When your class work tends to be things like homework problems, lab assignments, and in-class quizzes where answers are either right or wrong then your scores tend to be directly numeric. Grade inflation is a lot easier in "softer" classes where most of the scores are subjective. Though that can, of course, vary depending on the school, but the average certainly seems to be that way.

Cost aside, issues people have had with whiteboard paint:

* Cleans poorly, degrades over time, makes walls look messy

* Writes poorly (your wall is textured, a real whiteboard is flat)

* Smelly

We use roll-around whiteboards; we have an open office, though.

"I wonder if the dues from Google, Yahoo, the CEA, and Apple (all mentioned in the article for having or thinking about dropping out over politics), would be enough to bootstrap such an organization…"

None of those companies would be particularly interested in such an organization, as they are all monolithic "old" organizations in their own right. Apple, Yahoo, and Google don't want to push through legislation that would make it easier to compete with them. Apple, certainly, is uninterested in patent reform and Google's criticisms of patent law in the US are likely to subside as they build a big enough portfolio to successfully defend themselves from the Apples and Microsofts of the world.

There is a huge swing against C++ in the embedded world since 2007 or so. ABI issues, etc.

Not saying it disappeared, but there is now a bifurcation between C and C++ programmers.

What are the rules determining when you can? (I'm rather uneducated on markets).
Right, which is why he states TDD and agile development is best fit for consulting. It makes perfect sense there.
Wouldn't that be nice. Now consider the case of a pharmaceutical company that has to spend hundreds of millions of dollars to develop a new drug and get it past FDA. If there is no IP protection would you as the CEO of this company spend that kind of money on innovating when the resultant drug could be copied a week after it appears on the shelves? In this case you would be competing on product alright - exactly the same product. But the copier has had no R&D cost and can undercut you and put your offering out of business.

The issue is often framed in terms of all patents being bad, or all software patents being bad but to anyone to gives the matter more than the kind of superficial thought stemming from ideology the reality is rather more complicated.
Pretty addicting scrolling feature. An overload of information but a cool graphical way to see what's going on.
Who are these clients and why are you not firing them?

You run a business, they run a business, and everyone is trying to make money. How much money do you think an IE6 user has? the browser is like a decade old. It's why we target iPhone and not Android in the mobile world. ( because iPhone users out spend android users. )

Tell your client the truth, tell them that you keep up to date on the latest trends and if they want to use someone else let them, and then tell them exactly what your work will do.

I would not even offer to support IE6 anymore. Maybe IE7. There are a few reasons.

#1 you can't download IE6 legally any more

#2 you can't install it legally on linux or mac systems to test.

#3 IE7 in quirks mode does not work exactly the same as IE6.

#4 web development for legacy browsers is less about building things, and more about working around problems. and i just don't find that fun.

It is your duty as a web professional to turn down this work. Microsoft does not even support his browser anymore.

The reason why games are written in C++ is because the gaming industry was sold on the idea in the mid 90's and now all the tools are written in it.

For low level systems work, C++ can be considerably more difficult than C to organize and port large programs.

It isn't "C++ is always worse than C" it is "C is often better than C++ for a given task, depending on task"

Sweet idea, sweet product it seems. But that ad did not feel tasteful.
I was thinking of something similar. But I was thinking it should be a straight list (one article per row) and to the side should be a graphical bar. Mouse over the bar and the content goes away forever. So you can just swipe your mouse side-to-side over the bar to consume the content (and not see it again).

I'd love to see solid numbers on what percentage of their sale price companies are spending on different forms of advertising.

Considering the general bargain hunting nature of Groupon-derived customers I wouldn't be surprised if they're possibly the most expensive and the least converted advertising business out there.
There are several emacs-ish keybinding and behavior packages. Install Package Control and look through the repo.
There's too abrupt a distinction between integration and unit tests. Testing the behavior of your code before it's written can be organizing and efficient. Testing private methods or code that is otherwise internal, is, as was mentioned, an additional maintenance cost.
I love the Airs (my personal one is an 11" and my work one a 13").

The fact that the screen is smallish is great for me. I put apps full screen which is very good to focus on stuff.

Also, they are light. I don't think I ever want to carry a MBP 15" around anymore. Smaller lighter bag is great.

Hint: iTerm2 does Lion's full screen and has a new split screen mode, which is awesome!
I think this is a very sane approach. The same thing exists in vim for python (https://github.com/ehamberg/vim-cute-python).

Yes. I often flag articles that I think don't fit in with content of this site. That's what it's for. The quality of the content on HN is decreasing because literally any article about venture capitalism is somehow interpreted as being about technology.
True, but I would say that it is at the expense of long term value. If visitors recognize that the publication no longer delivers what is expected they'll stop coming, which lowers the value of the ad space.
I have a maxed out 13" MacBook Air for development and I love it. Being able to cart it around easily is great, and it's plenty fast enough.

I do have an additional screen and I'd definitely recommend at least having access to one if you need it. I have a 24" Dell Ultrasharp which more than makes up for the lower resolution of the Air, when (eg) I want to use Photoshop.
The main problem with this is that author is creating a false dichotomy between writing great software and running a business(hustling). I don't think you have to forgo one to succeed at the other.

I just think that you need to make a decision up front what your businesses core competency is, if it is supposed to be writing great software, then really should you be doing things like "Stop being such a nerd".?
I've heard great things about Anki. It's available for desktops, with sync, and they only charge for the iOS app.
The battery lights display useful information by being visibly off. When you see 7 dots light up, you need to be able to see the 8th dark hole to know it's at 7/8 charge and not 7/7 or 7/10. Similarly for the charging indicator: when it's not charging, you want that to be obvious.

Arguably, knowing that the laptop camera (or the wireless keyboard bluetooth pairing) is not active is not as useful information.

"US 7,657, 849 Apple 2011 Unlocking a device by performing gestures on an unlock image"

The details of the patent mention a predetermined gesture.

Moving from left to right is a predetermined gesture.

Is moving a ring from one area of the screen to another a predetermined gesture? If the final location of the ring is not consistent, could it be called a gesture? Is pushing a button a gesture?

It's things like that that make patents so questionable.
It surprises me that this has to be highlighted. I wouldn't genuinely know if it's a difference between British and American English but I've never encountered a British trend of using gender specific pronouns - or the unilateral usage of feminine pronouns in favour of masculine ones - in place of the neutral forms.

It is one of those niggles that irks my pedantic self though; particularly the politically correct change to using 'she' instead of 'he' (instead of the perfectly neutral 'they', and even 'one').
When in the making-of video they call it a labor of love, they meant it.

When you do something you love, streamlining the process -- removing stuff you love from your life -- is counterproductive.

Consider that people climb mountains they could hire helicopters to get to the top of. They train for months to run marathons they could drive in a car in under an hour. They change their children's diapers they could hire a nanny to do.
