sdfx··on The worst visualization I've ever seen (CNBC on the oil spill)
I've heard an interview on the planet money podcast some time ago where they had a teacher on. The teacher said, that she uses one dollar bills which she hands over to a student one bill at a time to give them a sense of larger numbers. She explains to them that it would take about 11 days to give them 1 million, but about 31 years to give them 1 billion. I thought this was a nifty way to 'visualize' these abstract numbers.
sdfx··on The worst visualization I've ever seen (CNBC on the oil spill)
There is a place for the "compare to everyday measurements" info-graphics. But as others have pointed out, it doesn't take a genius to understand that one gallon of oil has the same volume as one gallon of milk and 184 millions of anything is still pretty hard to comprehend.

And what are they trying to show with the boats? These boats don't even represent known quantities (eg. size of a football stadium, milk container etc.), they only show that some catastrophes were worse, some were less bad.

The stadium misses the point, just as the oil reserve by comparison. A comparison of the affected surface area in the first case and a comparison of the production of Saudi Arabia during the same time-frame would be much more useful.

Now, the bumper-to-bumper of trucks and the SF-bay graphics are not bad.

sdfx··on The Men Who Stare At Screens (why going to the gym might not be good enough)
From the abstract of the study:

Participants were 7744 men (20-89 yr) initially free of CVD who returned a mail-back survey during 1982. Time spent watching TV and time spent riding in a car were reported. Mortality data were ascertained through the National Death Index until December 31, 2003.

They noted that they adjusted for age. I presume other factors like the economic status correlate also with the time they watched tv. Don't know if they've adjusted for that as well.

sdfx··on QuickFuse
Yes, it reminded me of them as well. But while Yahoo Pipes look nice they get over complicated pretty fast. Flow charts for automatic call answering on the other hand have been around for quite some time and might be a better fit for such a representation.
sdfx··on Ask HN: Please review my startup Pretty Graph
Then why not skip the sign up page completely? Let everyone upload non persistent data with a limit on the number of data points.
sdfx··on Ask HN: Please review my startup Pretty Graph
Only few of your examples show off these features. I can replicate the rainfall and sales graphs in Excel in less time than it takes me to log in to your service. The heat map on your blog on the other hand looks great - why not replace the boring graphs with this one?
sdfx··on Ask HN: Please review my startup Pretty Graph
As I see it, you have a problem convincing people of the value of your service, particularly the value over a different solution (i.e. Excel). I like your Video on the Blog page and I'd move this to the first page. However, a scatter graph can easily be drawn in Excel - maybe add a more "awesome" example?

I don't know what you think of the freemium model, but it could be an alternative to your free trail. It could make sense to introduce a free product category with maybe 10 free graphs and datasets with less than n elements. This way, customers aren't bound by the 30 days and have more time to warm to your product.

You write that there are differences in the design themes across the different products (basic, designer, premium)? I'd explain the difference in detail - you could use a check list of the available features - so that it's clear why premium is better.

sdfx··on HTC 1
I share your concerns for the kick stand and the UV light. Maybe the UV light could be integrated into a docking station? While it's a strange thing to integrate into a phone, some people might value the perceived hygine.

Regarding your last point: How many people would change the inner workings of their device? I think a big selling point is the sleek look of the phone. You'd have to account for a lot of eventualities: What about a second camera, additional microphones etc.? How thick should it be, given that advances in technology could make it feasible to reduce the thickness significantly.

I'm not sure it's even possible to create a phone "for the ages". Even if you disregard the wear of the hardware: A phone design from even 5 years ago looks dated - maybe simply for the fact that it has been around for so long. And while you remain the same design, every company around you changes their designs.

At this point, the material cost of the outer shell of your phone is pretty insignificant compared to the rest of the hardware. You'd have to ramp up the value of the shell quite a bit to make it economical to keep the hull and change the innards.

sdfx··on Ask HN: What's the best feature you've built that no one uses?
What about curated author pages? Maybe with some information about the author and a list of his books by publishing date. I know, this may be too close to the Mahalo-model, but it could help with your low number of pages to index. You could start with your top searched authors.

And maybe you could show a little more information about the book when you click on it. I'm not sure what data Amazon provides - there must be more than just the picture, no?

sdfx··on Could Boxes of Water Help Reforest the World?
Or maybe they steal them in order to sell them back to you?
sdfx··on Could Boxes of Water Help Reforest the World?
Yes. Just think about how much more of these boxes he could sell if he produces them dirt cheap in China. This could easily offset all the negative impacts of shipping etc. He even says himself that if you plant enough trees, an increase in CO2 emissions can be offset.

Don't let the perfect be the enemy of the good.

sdfx··on UseTheSource: a place for beautiful code
I agree. Particularly the timelines of news makes a system where older stories slowly fade away useful. I guess it depends on whether useTheSource is supposed to be a "coding news" where you find great stuff accidentally (like hacker news), or whether it's a place to search for an elegant solution to a problem that bugs you (i.e. StackOverflow for pros).

Either one would be great.

sdfx··on Stop complaining and pay programmers more
Different people are attracted by different things. For one it's the money, for others the environment, culture or challenges. But usually it's a combination of all of these factors. You can't just disregard money as an influencing factor in the decision making process of a potential employee. After all, you wouldn't be working for free. Sure, there is always the exception to the rule - the person that isn't interested in money at all. But in general money is a pretty good incentive for doing something.

The salary that a company offers might not be listed in a job offering, but the culture and many other factors are neither. And even though they are not listed you probably heard of companies with a great culture etc. Don't you think the same is true for salaries?

sdfx··on Soccer and the law of large numbers
Luck is a big part of the appeal of soccer. As with most sports, you usually start rooting for the team that is popular in your area. With a significant reduction of this luck-component, strong teams would dominate the leagues which would in turn reduce the appeal for supporters of smaller clubs. Under the current rules, it's not unusual for a smaller team to win against a much stronger opponent from time to time. To tilt the probability towards the favorite reduces the appeal for supporters of the underdog.

It seems that people who grew up with high scoring games, exact time-taking and video referees often times feel the urge to "fix" the perceived flaws of soccer. I don't want to be snotty, but a lot of people love the game in it's current form. If you don't get what's fun about a good game that ends in a 1:0 that's fine, but please don't ruin it for the rest of us.

sdfx··on "Men Who Do Nothing But Think."
Sorry for the confusion. It's an 'artifact from a different time' in the sense that you'd use different words today. Not because the copy is sexist (which i still think it isn't) but because you'd try to avoid even the appearance of sexism.
sdfx··on "Men Who Do Nothing But Think."
I suppose you object to the phrase "Men who do nothing but think"? While sexism might have been prevalent in most companies during the time of this ad by modern standards, this phrase is not necessarily sexist. Sure, if you'd publish this ad today the silhouette would depict a woman and the text would be different, but "men" can be used in a gender neutral way [1] as in "All men are created equal". Take it as an artifact from a different time and don't read too much into it.

sdfx··on The Future of UI
These new UI concepts are always awe inspiring, but what is really the benefit of using them?

One of the most popular demonstrations is browsing through a bunch of photos on a huge screen with large gestures. While this looks quite impressive it's inaccurate when performing specific tasks (e.g. the color-selection planes in the video), the gestures are limited and you have to learn somewhat unintuitive ones apart from the more obvious "select", "move left" and "zoom" gestures. His more real world example (the table and the globe) didn't quite work, but what he could show us wasn't a step up from using a mouse.

An other favorite is the "physical elements on a table" example. This works reasonable well but his examples again were not convincing. Using it as a wind tunnel without being able to rotate it in three dimensions? Calculating the shadows of buildings?

But what's holding us back? Processing power? Cost? Hardware requirements? Or a general lack of use cases, of areas where this really makes sense?

sdfx··on Mastering The Fourier Transform in One Day

This is a great introduction to DFTs. I wish there were more write-ups like this. So if you missed it the first time around, check it out.

sdfx··on Rate my new startup, Appointment Reminder
I completely see your point about the fixed rate. However, the benefit of a flexible plan is that you can lower the price of the initial payment and make a little money every time you are really helping your customers (detecting a no-show). You potentially save your customer money and take a fee for this service. I get now that that's not what you want - just wanted to offer a different perspective.
sdfx··on Rate my new startup, Appointment Reminder
It's an interesting idea, but I'm not so sure about your price structure. I guess that you don't want to bill for every notification, but have you thought about billing for prevented no-shows (maybe on top of a base-price that includes x appointments)? You could still make the case that your Reminder pays for itself after the first no-show and make more money off of users that benefit more from your product.

Also: I don't know who the target audience for the base-price is. If you know you have 10 and only 10 appointments per month, this plan may be fine, but otherwise? Why not change it to a "1$ for every appointment"-Plan?

sdfx··on Laser Fence Zaps Mosquitoes In Flight
I love this very tongue in cheek, over-engineered solution to a real problem. It seems the authors are well aware that there are more cost-effective ways of dealing with the problem. But shooting the critters out of the air, one by one speaks to the geek in all of us. This would be a great "give one get one" device, but then again, giving to more conventional causes for malaria prevention is probably more useful.

And in case you want a local, mechanical option - don't those electric fly killers with the blue light work for mosquitoes as well?
sdfx··on Home Depot has to pay inventor $25 Million for stealing his invention
In the year before the devices were installed, the company paid out $1 million in claims related to injuries caused by the saw. In the year after the gadgets were installed, it paid out $7,000.

This is unbelievable - he saved them millions, jet they were not willing to pay him the $4M he asked for.

sdfx··on Four Nerds and a Cry to Arms Against Facebook
It's an odd choice to use a name with such strong historic connotations as opposed to something generic like Yahoo or Google. This might create expectations or alienate some users. And the asterisk is just annoying. But on the other hand, if they are successful the name won't matter one iota.
sdfx··on UXBASIS - UX in a box
The Product looks nice enough. But if the samples are representative of the product it looks like you are paying for glorified studying cards with little in-depth content.

Maybe this is based on a widespread model I am not aware of, maybe they are selling their consultancy services and this is part of it, but as a stand alone product I wonder how useful it is.

sdfx··on Teambox - open source project management tool
Are the features of the premium plan (search across all projects & time-tracking) part of the installation?

sdfx··on How inconsistent design will save iTunes
It's an interesting idea, but this could optimize the wrong thing. You already rely on function x heavily, so why should this function be featured more prominently? You obviously have no trouble finding it. Only because someone doesn't click on a button for some time doesn't mean he won't in the future.

Why not suggest a playlist with songs you listen to the most instead of making the searchbox bigger? Why not suggest songs to listen to next instead of hiding the genius bar?

sdfx··on Another view of game piracy
The average pirate downloads a lot more games than the average customer buys. This means that even though games see that 80% of their copies are pirated, only 10% of their potential customers are pirates, which means they are losing at most 10% of their sales.

This is simply not true: Sales are not distributed evenly amongst customers. It could very well be that people who are pirating would usually buy a lot more apps than the usual customer. Sure, if you don't have to pay for stuff you consume more, but they are probably more likely to spend more than average in the first place.
