state_machine··on Bill Gates On Nuclear Energy: Compared To Coal, It Is Still Safer
Apparently, TerraPower's TWR design doesn't actually burn from the top down like a candle anymore. I guess it's easier to put all the cooling apparati around one criticality region and then move the fuel through.

state_machine··on Ryan Dahl (Creator of Node.js) is doing an IAMA on Reddit
This (parent) is what pedantic means.

Also, depending on your thoughts on 4chan and reddit, you could say that differentiating between them is pedantic, but that's another question.

state_machine··on Npm 1.0 released (with global and local installation space)
Neither the command on the page, nor the script it downloads, use sudo (or su for that matter).

Just invoking 'sh' really should not give you a root shell under normal circumstances.

You can try running 'echo "whoami" | sh | grep root' to verify this yourself.

state_machine··on Why Instapaper Free is taking an extended vacation
I've been using Instapaper (mostly on programming related blog posts [standard WP/Blogger templates] and major magazine articles [Vanity Fair, Economist, etc]) for a while and rarely found this to be the case. It has almost always stripped unneeded markup well, often providing a superior reading experience on the iPhone than iOS Safari's rendering of the original content.

Are there any specific sites/types of pages you've had trouble with?

state_machine··on Amazon has gone from 26,100 to 37,900 employees in just one year
I think you mean some more engineers with world-class expertise in network storage: the fact that EBS/S3 have worked as well as they have at scale should indicate they have some already.

Sure, they have failures/slowdowns etc, but they are pioneering the space of providing massive infrastructure to heterogeneous clients at low cost, and still manage to keep it working enough that companies entrust their business to them.

state_machine··on A Collection of Examples of 64-bit Errors in Real Programs
Using stricter compiler flags is often the fastest and easiest way to catch such bugs. Here at CMU, we usually require all assignments for undergrad C/C++ courses to compile with no warnings using "gcc -ansi -pedantic -Wall -Wextra".

If you never acquire the habit of writing sloppy code and ignoring warnings, it's not even that bad. In fact, it's only the kids who already know C coming in who complain about the stricter flags.

state_machine··on AT&T to Acquire T-Mobile USA for $39 Billion
If they change the TOS, you'll have a chance to jump for free.

See article seven of the CTIA's Consumer Code for Wireless Service (http://files.ctia.org/pdf/The_Code.pdf):

"Carriers will not modify the material terms of their subscribers’ contracts in a manner that is materially adverse to subscribers without ... allowing subscribers a time period of not less than 14 days to cancel their contracts with no early termination fee."

state_machine··on Your Username Will Now Serve as Your Password and Your Password as Your Username
But it's faster that way, and you don't have to store the name in every row like with those No-Seequill whatnots.

</sarcasm>

state_machine··on New string search algorithm
Because 2, the exponent in that expression, is a constant.

Exponential growth would be 2^m.

state_machine··on Carnegie Mellon CS Professor challenges Sony by mirroring Geohot's PS3 hacks
From my experience at CMU, I'd say that isn't likely:

The administration is very cautious and conservative most of the time, and if they had been involved, this would have,at the very least, taken weeks to happen.

That said, the CS department head may have given him a thumbs up (probably even literally), knowing that legal will be forced to back them up, if he asked anyone at all before hand.

state_machine··on Ask HN: What are you working on over the winter break?
1) Writing a little RTS (similar to Space Game or Harvest, starting from creepsmash: http://towerdefence.hft-stuttgart.de/ )

2) Finding a job

3) QR Code Wrapping Paper https://github.com/tinystatemachine/QRapping-Paper

4) Learning Lift

5) A little app which parses police incident blotter PDFs and renders histograms, heatmaps, etc, of crime data

6) Arduino hacking with 802.15.4 (ZibBee) radios

state_machine··on "Google asserts copyright, even on work I do in my own time." (Snap framework)
Because it's probably not actually "wholly independent".

Software developers are thought workers, and you don't get to just check your brain at the door when you clock out like you could your tools or a laptop. Thus, any similar* work you do on your own time cannot be done without your brain using some of what is in your head, which you learned/figured out on company time.

* Now, this is the fun part. Where do you draw the similar line?

Think about it: you hire someone to solve a problem. You pay them to figure it out and implement. Then they turn around and implement the same solution, which you paid them to think about, for someone else?

state_machine··on Reddit’s Astonishing Altruism
But this kind of thing exists: charities and fundraisers are nothing new.

The fact that it is their reddit taking action, and not some church group or NGO, is probably what motivates at least some of the participants.

"upboat"

QED.

state_machine··on Show HW: UseSSL.org - shame list for unencrypted private info
I was a little taken back when I saw firesheep running on my university's (unencrypted) wireless network. The number of cookies/sessions being sent back and forth, and the ease with which they could be stolen, was staggering.

SSL has been around for awhile, the CPU time required is negligible compared to the other tasks most web-apps are doing now, and for any real business, the cost of a simple cert should be trivial. Plus, with SSL-offloading common on platforms like netscalers or aws EC2, many sites could probably support SSL without their web servers noticing.

I needed a quick (< 5 hour) project to try out rails3 and learn what changed, so this seemed like a good way to cut my teeth. I apologize it's ugly -- design isn't my strength.

state_machine··on Scribd Puts My Old Uploads Behind a Paywall and Goes Onto My Shitlist
Well, it's "not much of a response" since it doesn't respond to his concerns. Inviting him to give further feedback is great and all, but while it acknowledged his issues with the Archive paywall (just by saying they could tune it -- not with a concrete solution), it completely ignored his privacy complaint about broadcasting reading activity.

Basically, it was a response, but "not much" of one.
