maebert··on Workaholism in America Is Hurting the Economy
Uh. Hope my boss doesn't read this. ;-)
maebert··on Jrnl – A simple command line journal application
You mean when DayOne has a sync conflict? That depends on the method of syncing, I guess, which is different between DropBox and iCloud as far as I know. If I remember correctly, in iCloud the conflicting file will be ignored, while in Dropbox you'll have two entries. None of these is perfect I admit. If that's important to you, I'll look into it and we can come up with a well-defined behaviour for that, just open an issue on https://github.com/maebert/jrnl/issues !
maebert··on Jrnl – A simple command line journal application
Hi, creator of the package here. If you install the pycrypto package first, jrnl should work fine on Windows, too. It only needs a gcc compiler to build from source [1], but there are even pre-compiled binaries [2] (I don't have any experience with them though - please let me know if it works) :)

I think py2exe could work well, too! Otherwise you could create a virtual environment with virtualenv and install all the dependencies into one folder.

Nobody that paranoid should use an iPhone. Or any phone, actually...

Engineer @heyday here. We've already got an export-to-json prototype, but it's not quite ready for the public yet. And of course we want to export into a beautiful format for the average user as well.

Engineer @heyday here. Thanks for letting us know :)

I think the evaluation is based on the previous owner / user of that IP address (it's hosted on S3, and IP addresses are kind of like relatives on your family's christmas get-together.) I submitted the site for re-evaluation though.

maebert··on Ways to make yourself happier
Oh, I have absolutely no doubts about that! And from at least the review article they had on this page [1], it seems like the do some solid psychological assessment of gratitude. What does concern me though is when neuroscience is thrown into the mix just because everything seems more convincing with brain scans[3]. The articles <del>cited</del> referred to in the blog posts linked in the original blog post however often follow this pattern: (1) Assess X (say, gratitude) with an established or new questionnaire. (2) find a condition to vary (3) do a fMRI in both conditions and (4) correlate the contrast with the questionnaire. If you found a correlation, you found the neuronal cause for X! Publish!

This is just a huge waste of money. And also often enough poorly done [2].

maebert··on Ways to make yourself happier
Am I the first one to call this article out on BS pop neuroscience? If you want to convince yourself that this makes you happier, just go and try it, but completely context-deprived pictures of colourful blobs on a 3D brain proves... nothing. Oh, you need sleep to be productive? Let's run a poorly designed $20,000 fMRI study to prove that! Folks, this has to end.
maebert··on FMRI Imaging of Dreams
Apart from the populistic BS that the magazines blow all things neuroscience up to, the machine learning technique behind these kinds of studies are actually very clever (and a lot more robust than most "traditional" fMRI findings that produce headlines like "scientists discovered brain area causing teenage angst". If you want a former neuroscientist ranting about bad fMRI research for a page or so, let me know :)

maebert··on Teach kids to farm, not code.
"A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects." In that sense: learn to farm. And to Code.
maebert··on Why Telling a Story is the Most Powerful Way to Activate Our Brains
Sometime I'm going to write a piece "Why you should not follow links that include the word 'brain'".
maebert··on Things That Are Never Admitted About Open Source
This article, while making many valid points, seems to focus on open source software for consumers - FOSS2C if you will. However, the last decade has shown an incredibly rise of open source solutions for developers, and I think most people here can readily name five or more open source tools without which their daily work would be absolutely unthinkable.

And in these areas, points 7, 8 and 9 (regarding lack of innovation, monocultures and lack of goals) are simply not valid, 4 (meritocracy) is not as bad as in projects that have been running for several decades (who would have thought?), and 1 and 3 simply don't matter.

maebert··on My Top Sublime Text 2 Plugins
You're welcome, sir!
maebert··on My Top Sublime Text 2 Plugins
#1 should be SublimeCodeIntel, not SublimeLinter - otherwise thanks for this list, I didn't use Emment before but will certainly give it a spin.

maebert··on Julian Assange: Wikileaks to release 'million more files in 2013'
While I'm generally supporting Assange in his mission, I do wonder what good has come out of the released cables and other documents so far. Have there been any policy changes anywhere as a direct result of the leaks? Until now it seems like wasting taxpayer's money on making dubious sexual assault charges an international diplomatic issue and possibly unconstitutional torture of a whistleblower are the only effects that ripple through the media. Am I missing something?

maebert··on Redactor - WYSIWYG editor on jQuery
Version 7.6 is on Github under CC-non-Commercial: https://github.com/dybskiy/redactor-js

Even version 8.03 (august 20120)seems to be free (http://imperavi.com/webdownload/redactor/getold/), the new licenses got apparently introduced in 8.1.0, which adds a plugin system and some other stuff (http://imperavi.com/redactor/log/)

maebert··on The Differences Between Germany and the United States
Then again, others are not (e.g. he references the abolishment of compulsory military service in 2011). I think the article is still under constant editing, it's just not possible to catch up with everything at once.
maebert··on The Differences Between Germany and the United States
Mistakes yes, but I think he got most of the core motifs right (on both the US and German side (I grew up in the latter)). With which points (concerning the US) to you disagree / which points to you find questionable (BRD)?
maebert··on Blind man shocks researchers with what he sees.
The term "recognising" is a bit misleading here. Blindsight is in fact a very nice case where traditional cognitive science and AI paradigms suggesting a hierarchy of processing (bottom up of primal stimuli until they end up as meaningful concepts, top down of thoughts until they turn into actions (roughly)) doesn't quite fit.
maebert··on Blind man shocks researchers with what he sees.
I think it's a bit more complicated, since mammals without consciousness (ouh, vague concepts ftw) still show immediate reaction to visual stimuli, where as patient TN and others can react and act upon to visual stimuli, although the traditional "chain of command" is broken.
maebert··on [dead]
Ex-Neuroscientist here. Your explanation is quite accurate, though I believe they use a more modern variant called Diffusion Tensor Imaging. The idea of MRI is that you put the brain into a huge magnetic field, switch the magnet of and count how long it takes for the nuclear spin to jump back to random states in different areas of the brain - this time is specific to each different atom and allows for an estimate of the concentration of different atoms (like water). In DTI, the hypothesis is that water molecules line up with the neurons axons (the long cables that connect neurons to distant other neurons). If change the direction of the magnetic field gradient a couple of times, you don't just get one value per voxel (how much water is in there), but slightly different values for each direction. The highest value is _probably_ the direction of alignment of the majority of axons in that voxel.

The problem is not the tool, but the statistical analysis of the data, which depends on a lot of parameters, and the number of different gradient directions, which are usually orthogonal, hence favouring orthogonal neuronal connections and discounting those that are diagonal to the gradient directions. You have to correct for this in the analysis, but it's very hard to do, and mostly guesswork. Which coincides my personal evaluation of the entire study: guesswork.

maebert··on Renewables now account for 25% of German energy production
That would be new to me - people here have been able to feed in excess energy to the grid for more than two decades. The real problem however is that the traditional power suppliers are forced to pay users that _feed in_ a very lucrative amount per kWh they produce in excess and recently started to rebel against that policy. So I wouldn't be surprised if the "technical problems" are somewhat politically/economically motivated.
maebert··on A technique for hiding your JavaScript code
Hm, has anybody thought of QR codes containing javascript already?
maebert··on A technique for hiding your JavaScript code
Bonus points for not just creating an image, but hiding the code steganographically in an existing image (ie only using the LSB of each pixel to hide code)!
maebert··on 2 month hackathon on a remote tropical island
I'm actually very intrigued, I just booked a flight to Indonesia to spent a month or so hacking / designing for myself in Bali, but doing this with others sounds like a much better plan. Any details on the schedule yet?
maebert··on Should I launch my site now?
Launching early is always a good idea, and there's nothing like real customer's feedback to help you prioritize your quadzillion ideas.

However, I strongly suggest you spend some time on copy and structure of your landing page - without reading your post here I would have no idea what your service had to offer me, and my motivation to whatch youtube videos on landing pages has been rather low lately. :)

maebert··on Ask HN: What do I need to know to move to Berlin?
Re 2) Hiring in Berlin is indeed difficult. There's a great influx of talented developers from southern Europe though, and as long as your employees come from within the EU hiring them is not a problem.

Re 1) Not entirely true for startups - most developers joining startups know what they're at and are not unionized; still you can't fire people at will. Typically this problem is solved by limiting contracts to a couple of months and extending as long as there is money left.
