palebluedot··on MtRed Bitcoin mining pool will be shutting down
I'm not sure this is true. For example, consider the following scenario at $200 USD per bitcoin: 5 people pooled mining capabilities, and mined a single bitcoin. They could then split that, and effectively pocket $40/ea (or 0.20 bitcoins each). If you mine solo, is it possible to mine a partial bitcoin, rather than increments of a whole bitcoin?
palebluedot··on IRS claims it can read your e-mail without a warrant
The problem is this works only with 2 parties that have already agreed to, and are willing to use, encryption. How many websites, services, and other sources of email have an option to encrypt your email to you with your public key? Not many at all.

I've stopped putting my public key on emails I send, because almost no one ever encrypted email to me, unless they were specifically sending something perceived to be sensitive.

palebluedot··on SpaceX Launching Dragon Capsule to Space Station
And, one last update (my edit window has passed, sorry):

"Pods 1 and 4 now online and thrusters engaged. Dragon transitioned from free drift to active control. Yes!!" https://twitter.com/elonmusk

palebluedot··on SpaceX Launching Dragon Capsule to Space Station
Elon just tweeted: "Issue with Dragon thruster pods. System inhibiting three of four from initializing. About to command inhibit override."

Edit: https://twitter.com/elonmusk/status/307515784610058241

Edit 2: Follow-up tweet from him: "Holding on solar array deployment until at least two thruster pods are active"

Edit 3: Looking better! Latest tweet: "Thruster pod 3 tank pressure trending positive. Preparing to deploy solar arrays."

Edit 4: YES! "Solar array deployment successful"

palebluedot··on SpaceX Launching Dragon Capsule to Space Station
NASA TV just said that they will have a status update on the mission, at 11 AM Eastern time (so, ~15 minutes).
palebluedot··on SpaceX Launching Dragon Capsule to Space Station
Uh-oh - they just announced that Dragon is having problems, and there should be a press conference in about 30 min. I hope it is not major.
palebluedot··on Google Fails the Turing Test
I am a big Google proponent, and Android user. But the problem is deeper than just a smooth launch, and the number of issues at launch.

It is a systemic customer support issue that, while perhaps understandable for a free product, is horrendous for a merchant or paid product. I don't think people would care nearly so much about launch hiccups, even major, if there was customer support to help resolve the issue. But as it is, whenever you order something it can feel a bit like Russian Roulette with Google. I hope this changes soon, because otherwise they are doing awesome stuff.

palebluedot··on NVIDIA Tegra 4 processor details leaked
The Tegra 4 is based on the Cortex A15, and the A15 makes things very interesting for high-power ARM mobile computing. The A15 supports hardware virtualization, and already has preliminary support in QEMU/KVM. A tablet with hardware virtualization support would be very interesting (well, at least to me :))
palebluedot··on Technical founders have nothing to lose
This seems a bit naive - perhaps it would be better targeted as "technical founders need less capital".

For instance, you still have legal liability risks, which may vary depending on the problems your startup / business is trying to solve. Especially in the early stage, even if you have a corporate entity wrapped around your startup, mounting a legal defense can be financially crushing. This is doubly true if you are augmenting your cash stream by consulting / contracting.

This may not be very likely, depending on the startup - but to say technical founders have nothing to lose seems a bit naive.

palebluedot··on Amazon Instant Video on Apple iPhone, iPad, or iPod Touch
Because on a Nexus 7, you might also go to the Google Play store to buy books, music, or videos. But Amazon has removed that from the Kindle Fire.

That is the madness of which I speak. Because they are afraid that if I don't use the Kindle Fire I won't buy videos, they therefore won't let me buy videos unless I use the Kindle Fire. It seems like a self-fulfilling prophecy to me. That same logic would call for them to not have a Kindle app on the Nexus 7, would it not?

palebluedot··on Amazon Instant Video on Apple iPhone, iPad, or iPod Touch
I agree. However, the Kindle Fire exists primarily to facilitate sales, including video sales. I don't understand why they are so passive aggressive towards Android users who do not buy the Kindle Fire, but want to rent videos. Honestly, as an Amazon prime subscriber, this dismissive Android treatment diminishes the value of Amazon's ecosystem for me.
palebluedot··on Skype vulnerability allowing hijacking of an account if you know just the email
Yes, but one of the great things about having GApps with your own domain name, is that you are not tied to Google as an email provider, and can easily switch. If you use something like the '+' modifier, then if you switch away you need to switch to someone that supports the same modifier.

So if your goal is to maintain email-provider independence, then relying on provider-specific features like the '+' modifier works against that goal.

For me though, the main reason I don't use it is most sites that I want to use it on reject the '+' in the address as invalid. It happens enough that I don't bother trying anymore.

palebluedot··on Facebook fought SEC to keep Mobile risks hidden before IPO
> Lots of people (myself included) had been saying that Facebook was overvalued pre-IPO.

You could have shorted the stock or traded options.

Before you short any stock, it is wise to keep in mind the maxim "Markets can remain irrational a lot longer than you and I can remain solvent". This isn't really a problem on the long side (sans margin), but is a real problem on the short side.

palebluedot··on Formlabs: High Resolution 3D Printer
I've seen some answers to your questions with regards to resolution, etc., but none to the part that is of interest to me: how does the PLA/ABS plastic of the Replicator 2/2X compare to the SLA, once printed, in terms of durability?

I've had SLA models professionally made, and they came with a warning to handle them gently, because they were brittle and not very strong (and, they were expensive).

Does anyone know, if you were to use the Form 1 for something like hobby robotics (i.e., outside of just design prototyping, but as a printer for parts), would it hold up well?

palebluedot··on Tesla Motors Launches Revolutionary Supercharger for Long Distance Driving
I am a Tesla shareholder, so I definitely believe in what they are doing, and think they are a revolutionary company. However, it is more than just the short-term revenue adjustment affecting the stock price - in addition to revenue drop, Tesla also announced an additional stock offering[1], essentially diluting existing shareholders.

With 105M shares currently outstanding, and Tesla planning to offer 4.34M shares, 4% of today's drop is likely just the market adjusting for upcoming dilution.

As a (very very minor) shareholder, I am glad they are doing this - relying on the current cash position and cash flow to get to profitability would have been cutting it too close for comfort, IMO. From an investor's perspective, I view Tesla as not much different than investing in a biotech - it is likely either going to be a huge hit, or a huge miss. The difference (for me) from a biotech is I feel I can understand and follow the tech in Tesla, and I believe in the company.

palebluedot··on Facebook Users Report Seeing Old Private Messages Showing Up On Timelines
This seems to be anecdotally confirmed by multiple people here. To me, if true, this screams of a broken engineering culture inside Facebook, where the model for data privacy and security is secondary, not primary. If this is indeed verified, no one should ever use Facebook for anything truly private, regardless of what apologies or excuses are made.

It is difficult to think of something like this, where private emails are accidentally disclosed publicly en masse, happening with gmail (or any other email service).

palebluedot··on Do 320kbps mp3 files really sound better? Take the test
Very interesting. This then set me off reading about ABX testing for longer than I wish to admit. For those looking to try some ABX testing between 320kbps and 128kbps mp3 files, this is the best in-browser one I've found so far: http://mp3ornot.com/
palebluedot··on Why I now, unfortunately, hate Hacker News..
The idea I'm currently investigating, in case anyone is curious, is that votes rather than comments may be the easiest place to attack this problem. Although snarky comments themselves are the most obvious symptom, I suspect that voting is on average dumber than commenting, because it requires so much less work. So I'm going to try to see if it's possible to identify people who consistently upvote nasty comments and if so count their votes less.

Interesting - also, if it is as you suspect and voting is easier and thus part of the problem, perhaps adding more friction to the process of voting would be useful. Something like having to spend karma to vote, or having a limited number of votes per day to spend.

palebluedot··on Can’t monetize free users? Try threatening them with legal action
OK - re-read my comment with the word 'unsolicited' removed.

It is still unreasonable to send out legal threats because you did not receive a response from an email. You don't know if the email was read, or if it was even delivered to the user's inbox (it could have been flagged as spam, for instance). Or, as it appears to be in this case, it could have a poorly worded and misleading subject, causing it to be ignored.

Furthermore, did you read the email that was actually ignored? It is linked in the article, and located here: https://gist.github.com/1833289

Note that it specifically says that "if you agree to this arrangement" to implement the link back. There is actually nothing in that email that would suggest that any action was required; the next step sans link back was simply for Gigya to then send a price quote.

While I am not suggesting that the alternatives offered are or are not fair or reasonable, the follow up email did its job in getting the service consumer's attention and more importantly action in regards to the matter.

Well, naturally. I was not arguing that being unreasonable was not effective in forcing action on someone's part. I would argue, however, that it is unethical and counterproductive.

palebluedot··on Can’t monetize free users? Try threatening them with legal action
I don't think this is totally unreasonable. From their point of view, they offered a perfectly reasonable alternative to paying, which was ignored.

By ignoring (accidentally) the original email, the message sent back could be interpreted as: "We're not implementing your link back, and we're not paying for your service, but we're still going to use it anyway".

Wait, what? So - if I ignore an unsolicited email, that suddenly becomes actionable if I don't do what the email says? I have a hard time seeing how that is not totally unreasonable.

The only reasonable nuclear option for them that I see, would be to simply terminate the user account or service, if they did not respond.

palebluedot··on Stack Exchange: How does noise affect programmer productivity?
Sorry, on the deck on the Enterprise :)
palebluedot··on Stack Exchange: How does noise affect programmer productivity?
In my experience, it isn't noise itself so much per se, but the type of noise - talking in particular is distracting to me. But I do find that some types of music, and noise, seem to engage my brain in a way that lets me focus better than with no noise at all... and as a bonus, it also drowns out some of the more distracting noises. Ambient music, some electronic music, and computer generated sound really help me.

If I were to start up a company again, I would issue each employee a nice pair of over-the-ear noise cancelling headphones as part of their office equipment. I think it would work wonders for their productivity.

Related - for some pink noise, here is a commandline (for those with sox installed) that I find soothing. Play with the last two variables some, to tune it to your tastes - it has somewhat the effect of noise from an empty beach:

  play -t sl -r48000 -c2 - synth -1 pinknoise tremolo .1 40 <  /dev/zero
I posted the above not too long ago in another story, and someone else (shmerl) replied with another one, that resembled the noise of [edit: not space] Star Trek:

  play -c2 -n synth whitenoise band -n 100 24 band -n 300 100 gain +20
palebluedot··on Apple announces iBooks 2, iBooks Author to "reinvent textbooks"
No, but I think some may be indifferent to it.
palebluedot··on Apple announces iBooks 2, iBooks Author to "reinvent textbooks"
Further, all the books had physical DRM. The glue they were bound with and the cardboard the covers was made out of was designed to disintegrate over the course of a semester, even with good care. I kept my books on a shelf next to my desk in my dorm and never took them to class, and still couldn't sell them at the end of the semester because they'd fallen apart.

That is not DRM. That is shoddy craftsmanship, poor quality, etc. But it is not DRM. DRM specifically limits your rights - Digital Rights Management - with regard to the content.

Plus by definition if you create software which supports new features you have lock-in.

Not necessarily, if it is an open standard - and if it is an open ePub 3 standard, then that is great. However, if it is DRM inhibited, then it is enforced lock-in. However, interoperability is key, so it needs to be both an open platform, and DRM-free. And it would be disingenuous to argue that the book format is an open standard, if it has non-open DRM locking it down. The DRM becomes part of the book, and cannot be separated from the standard, at that point.

I am not arguing that the college textbook industry does not need reform, or is not prohibitively expensive. It does, and it is. I am arguing against DRM in textbooks, and device lock-in.

palebluedot··on Apple announces iBooks 2, iBooks Author to "reinvent textbooks"
Interesting that I am receiving downvotes for this comment (although there seem to be some upvotes as well).

It isn't a bash against Apple - I would have the same concerns if it was Amazon or Google, if there was DRM and/or device lock-in.

And I think ebooks could be very good for students - however, limiting it with DRM and device lock-in is not how it should be done.

palebluedot··on Apple announces iBooks 2, iBooks Author to "reinvent textbooks"
Yes, I agree - Many public schools charge a 'book fee' each year, for textbooks. Just roll it into that - who cares if the textbooks are shared then, because each student is paying for it, regardless. And if it is in a non-proprietary format, that would alleviate the other concern of lock-in.

But one article mentioned that students could not resell the books - which implies DRM.

Outside of high school and into college, the publishers obviously want to prevent reselling/sharing of the books.

palebluedot··on Apple announces iBooks 2, iBooks Author to "reinvent textbooks"
I see many comments about the cost of an iPad - that is not the real issue here. The real issue is these textbooks and knowledge will be funneled through DRM, and a single provider (Apple). Even if Apple gave away the iPads, I will still have issues with DRM on textbooks. And even if these books end up being DRM-free, will they still be proprietary to Apple's platforms?

If most/all schools adopt this and require it, and the books are DRM hindered to a proprietary platform, then that means that it will become a defacto requirement for every student to own an Apple device, in order to receive education.

It may work, and would certainly be good for Apple... but I don't like it.

palebluedot··on How to nap
Here is a way to generate simple, wonderful pink noise (with a slight tremolo) from the commandline, if you have sox installed. It somewhat mimics the sounds of waves on a beach - I find it very relaxing.

A nice side affect (and the reason I played around with it originally) is that it helps mask tinnitus when it gets too annoying (I find that if tinnitus flares up too loud, it can make it more difficult to fall asleep).

The cmdline:

  play -t sl -r48000 -c2 - synth -1 pinknoise tremolo .1 40 <  /dev/zero
palebluedot··on Let's update the HN circle on Google Plus (the proper way)
True, it is possible that two people have the same name. I guess the uptake is to just take the list with a grain of salt. And, thanks for compiling the list - even with possible errors, it is nice to have.
palebluedot··on Let's update the HN circle on Google Plus (the proper way)
Some of the entries are obviously added by others, and not even necessarily even the right profile. For instance, Paul Graham is in the list (and in the shared circle), however it is not pg: https://plus.google.com/114939270563299965266/posts
