Matti··on Kalzumeus Podcast 5: Quitting Consulting Via Productization
The "jump" is seldom more than a decision to change your path. Robert Ringer's Leapfrog Theory states: "No one has an obligation—moral, legal, or otherwise—to 'work his way up through the ranks.' Every human being possesses an inalienable right to make a unilateral decision to redirect his career and begin operating on a higher level at any time he believes he is prepared to do so."

For a certain type of engineer everything involving sales, marketing, discussions about perceived value and getting paid tons of money for something that basically equates to "advice giving"... will seem strange and weird.
Matti··on The Christiania cargo bike
Leaner and lighter variants -- such as the Bullitt -- exist: http://www.larryvsharry.com/english/index.html (~24 kg, decent maneuverability, not much wider than a regular bike)
Matti··on New cheap VPS provider, based in Sweden
It's not immediately obvious but they are an off-shoot of FS Data -- a fairly well-known (and old) Swedish hosting provider. It is in other words unlikely to be a "fly-by operation" in a niche where new companies pop-up very frequently.
Matti··on Miniature Quadruped Robot Is Blazingly Fast
"What makes the robot wicked fast is the fact that it's got four independent drive motors, each one of which has a power to weight ratio that's absolutely bananas. Only 6 millimeters in size each, the motors output 1.5 watts of power at 40,000 RPM, driving the individual whegs through 16:1 planetary gearheads. They're not cheap (hundreds of dollars each), but they make for one crazy little robot. And of course, independently driven whegs make the robot smaller, lighter, simpler to steer, and generally more efficient overall"

What are my current alternatives if I want to build something similar and I'm only willing to spend say $50 per drive motor?

Matti··on Physicist proposes new way to think about intelligence
Where do you see it learning to walk? You can't equate the inverted pendulum problem with upright walking. It is neat if it can choose it's own reference level ("goal") for a classical control problem -- but that's a long way from "learning to walk".
Matti··on Jakob Nielsen's site has been redesigned
The more memorable version that most of us probably remember as Nielsen's site: http://web.archive.org/web/20120530170411/http://www.useit.c... (The same design was used for ~13 years and often evoked strong responses from web designers.)
Matti··on How to Not shut down a 'backup' service.
From the email sent on Feb 21:

" Today we want to share the exciting news that our team is joining another company that will utilize the Memolane features in an expanded way, adding more value to all the great memories captured on social media.

Unfortunately this also means that we will be shutting down the memolane.com service. Your account with Memolane and all its content will be deleted on Friday Feb. 22th. "

Matti··on Death in Singapore
Not the first death of that kind in Singapore:

"Family suspects interference in David Widjaja case"

http://sgforums.com/forums/3317/topics/363855

"However, it appeared the court process was intentionally directed to a conclusion of suicide despite evidence showing a strong possibility of murder, according to David's family and the verification team.

"We have strong evidence that he was murdered but that fact was not brought up in the court," David's father, Hartono Wijaya, told a press conference Tuesday at the National Commission on Human Rights."

[...]

"He added there was a suspicion David's death was related to his research: "Multiview Acquisition from Multi-camera Configuration for Person Adaptive 3D Display".

"His friends said his three-dimensional study could be used for various purposes, either for entertainment or even for military needs."

"And we must not forget that after David's death, there were two unusual deaths at NTU - his professor's assistant *committed suicide' four days later and another researcher was hit by a car 25 days later.""

EDITED: Having read more about the specific case, it seems to me that the official story sounds plausible enough. It's not at all clear whether there was foul play involved.

Matti··on Scientist Gets Research Donations From Crowd Funding
"A common myth regarding science crowdfunding is that only charismatic projects are funded. The topic of the research, however, is less important to the project’s success than the crowd a project engages. Almost any topic in science can be made interesting to audiences. For example, as part of the #SciFund Challenge (a science-specific crowdfunding initiative) many esoteric projects have been successfully funded. From a project researching the dormant stages of Daphnia to another investigating pure ecological statistics, projects that appear to have limited public appeal have been successful, due to the tremendous outreach campaigns by the scientists behind them."

Matti··on Introducing The Paper Bay
The filling a request process appears to be more complex than it is due to superfluous form fields. The information about authors, title and DOI has already been entered by the requester. For the service to be a viable alternative, it should be (and appear to be) extremely simple to fill a request.

Tracking down a paper is time consuming enough, even if you are sitting on the network with access to most journals. Don't make it look like people have to type in additional information manually.

Matti··on TPB AFK: Watch and Download The Pirate Bay Documentary
It's a mistranslation, and you are ignoring the context.

He points out that every time he has been beaten up or robbed the assailants have been immigrants. And by immigrants, he clarifies, he is not talking about 7th generation Finns but about "turkblattejävlar". The phrase he uses can't be directly translated. It's a generalized racial slur of moderate intensity with a clear subtext of social class.

In the context, and when contrasted with "7th generation Finns", he is using the phrase to refer to a certain demographic: young males of low socioeconomic status, most likely originating from the Middle-east or North Africa. In polite conversation this is the subset of the population that you would euphemistically refer to as "ungdomsgäng" or "youths".

But, as you can see, he is not in a polite conversation: he's in a pub, he's drunk, and he has just called brokep "a fucking vegetarian leftist bitch ass bastard" who's driven by "ideological pussy-inflicted instincts". In that setting and with that tone the phrase was at most a less than appropriate way of referring to his attackers — hardly an exhibit of "right wing racism".

By right-wing racist, are you talking about Fredrik whose children are mixed-race (note the clips where he got married in Laos) or Carl who's married to a jewish woman?
Matti··on Preventing users from pouring water into coffee machine beans compartment
A label saying "This container is for coffee _ _ _ _ s" with a lettered padlock (http://wordlock.com/padlocks/) would perhaps be preferable to the hidden key solution.

It would be interesting to have this contrasted with an article written about the same age span 75-150 years ago.

Matti··on The Nordic region is becoming a hothouse of entrepreneurship
Getting by in Stockholm won't be a problem: you can safely assume that people within the start-up scene are fluent in English. You'll be met with a slightly different kind of problem: as communicating in English is so effortless, you'll have few opportunities to really practice your Swedish.
Matti··on The Nordic region is becoming a hothouse of entrepreneurship
Unless things have changed recently, Berlin still has fairly low rents and low living costs going for it -- giving people a fair amount of marginal space: http://www.paulgraham.com/marginal.html

Alexander Young (of Soundcloud) speaking about Berlin: "The atmosphere and culture in Berlin is very unique. Since the costs for living are still low, people can afford to only work a few hours per week, and do the stuff they want the rest of the time." http://blog.twingly.com/2010/05/18/from-stockholm-to-berlin-...

That can't be said about Stockholm nor Helsinki.

Matti··on A student's grandmother is far more likely to die just before an exam
Along the same lines: for a young college student the death of a grandparent might very well constitute the first experience of losing a family member. With little experience, it's not always clear how these situations should be handled with respect to work or school. More mature individuals are more likely to handle deaths within the family with discretion.

With increasing age it is also more likely that you've already had your grandparents die.

Matti··on American Dream Fades for Generation Y Professionals
"In perhaps the biggest surprise, Armor's studies found that black elementary students who go to magnet schools (which have the highest percentages of whites) score no better on standardized tests than do blacks who go to all-black nonmagnet schools.(97) In short, Armor found that, contrary to the notion on which the whole desegregation plan was founded--that going to school with middle-class whites would increase blacks' achievement--the Kansas City experiment showed that "integration has no effect."(98)"

Matti··on Subtle Sans: A Free (Pay What You Want) Font
Set the default price to $15, $20 or $30 instead of the $1 that it's at now. You'll increase the perceived value of the font while making a ton more money. There's no point in having the initial price "anchored in" at the ridiculously low price of one dollar.
