Looks like it is possible, but takes a pretty decent amount of force: http://youtu.be/znK652H6yQM
pcarmichael··on Make Things and Show Them
Replies to an Ask HN post almost four years ago were instrumental in gathering feedback and cementing the direction for my then fledgling site. A bit later it went from side project to full-time work, so I always keep an eye out for Tell HN and Ask HN posts.
pcarmichael··on How to Avoid Sleep Debt
I'm trying to get my business off the ground while raising two kids under 5. I'm constantly between 5-6 hours of sleep a night. It's a vicious cycle - the longer it goes the more I need to work late to catch up. Yet the later I work, the less efficient I become. I know that I need a good sleep reset, but there never seems to be a good time. Exercise become difficult to schedule, and I've definitely gained weight over the last several years. It's not good, but the decline is slow and hard to recognize in the moment. It's been so long (4 years now?) that I think I've forgotten what feeling rested feels like.
pcarmichael··on F.lux updated
I had the previous version installed on my mac, and kept seeing sporadic issues with my mouse cursor jumping a couple hundred pixels at once when moving it side to side. Finally disabled F.lux and the problem went away. Anyone know if the new release fixes that issue?
pcarmichael··on A robotic dragonfly with a wingspan of 63 cm
While I am amazed at the engineering and seriously impressed at what they accomplished, I can't help but watch the video and think that that is one portly-looking dragonfly.
pcarmichael··on Intel 'preparing' to put an end to user-replaceable CPUs
I run a site dedicated to people who build their own computers. Like you, I am not terribly concerned by this move. From my experience, the number of people who upgrade CPUs keeping a given motherboard, or upgrade motherboards keeping the same CPU is very limited. CPUs typically don't depreciate in value that much, and by the time someone does decide to upgrade availability is limited to the point that prices often go up rather than down. If you wait a year or two, it's often more cost effective to just upgrade both.
pcarmichael··on Company withdrawing from Facebook as analytics show 80% of ad clicks from bots
If it was coming from Facebook, I would expect not to be charged for the clicks.
pcarmichael··on Why I'm an Entrepreneur
Thanks for this yesimahuman - it was incredibly timely for me. Today was my last day at a corporate job, and the first day of being a full-time entrepreneur. I know that I've got a roller coaster of emotion ahead, but it's encouraging to know the highs are higher than the lows are low.
pcarmichael··on Newegg refuses to repair defective laptop because user installed Linux
Thanks, Alex. I've really appreciated the feedback and encouragement you've given me.
pcarmichael··on Newegg refuses to repair defective laptop because user installed Linux
Definitely. No ETA yet, but that is on the roadmap.
pcarmichael··on Newegg refuses to repair defective laptop because user installed Linux
Thanks! I've fixed up the motherboard price for Amazon, though the price I list is when fulfilled from Amazon.com directly and not from their marketplace merchants.

Out of curiosity, how did you hear about pcpartpicker? (I created it, so I'm always interested to know how people find out about it. Hope you find it useful!)
pcarmichael··on Proxino (YC S11): Automated Error Reporting For Your Client-Side JavaScript
Is it just me, or does the pricing seem a bit steep? (https://www.proxino.com/plan) The free tier buys you roughly 33 page views a day, which I'd expect to surpass just handing a site to a single user or two. At $100/100K page views (which is not terribly hard to reach), that's getting pretty pricey.
pcarmichael··on Amazon offers Texas 5,000 jobs in trade for sales-tax exemption
Without a presence in Texas, Amazon is not obligated to collect sales tax. However, the customer must then pay a 'use tax', which is the same rate as the sales tax: http://www.window.state.tx.us/taxinfo/sales/faq_use.html

What the public in general seems to miss is that the tax revenue is due one way or another - either Amazon collects or customers self pay. Most of the public who are not business owners do not realize they need to self pay - it is neither enforced nor made obvious that one needs to do so. So instead of making the public aware of 'use tax' and trying to enforce it, the Texas legislature is trying to change the definition of an in-state presence to include independent subsidiaries, affiliates, etc. Then by doing so, the government can force the merchant to collect the taxes owed for them.

The first 'internet sales tax' bill was passed by the legislature but vetoed by the governor. Similar language was added to an omnibus spending bill, which is much more likely to survive.

pcarmichael··on Announcing the Facebook 2011 Hacker Cup
I completely agree the ICFP contest matches real-world problems better. I can't recommend it enough. The longer timeframe requires discipline and good planning, while also providing a bit of a buffer for early (minor) mistakes.

Having a strong and well organized team is huge. You'll learn a lot about your teammates in the process, both behaviorally and technically. However, I've had to go solo the last two years and still enjoyed it immensely - it just changes how you prioritize some of the development.

pcarmichael··on Why are we limited to JS in browsers - would a bytecode standard help?
One difference is in compiler optimizations. For a given language, compilers can often make inferences based on the code and the semantics of the language, allowing for very targeted optimizations. If you go from LanguageFoo -> Javascript -> bytecode, then you may be limiting the range of optimizations possible (because Javascript may not be able to infer the same things about the code, be it because of program structure, language semantics, etc.)
pcarmichael··on Ask HN: Review my webapp PCPartPicker: pick parts, build a pc, compare prices
(Too late for an edit, but I'm going to roll back the Disqus integration - at least until I settle on a community involvement strategy.)
pcarmichael··on Ask HN: Review my webapp PCPartPicker: pick parts, build a pc, compare prices
I like the idea of promoting the featured system aspect more. The ability to fork a configuration is already there - perhaps not visible enough (the "Edit this part list" on permalinked/featured part lists).

Disqus was a great idea. I've added it to the bottom of the part list pages. I'll look into adding it to the individual part pages.

pcarmichael··on Ask HN: Review my webapp PCPartPicker: pick parts, build a pc, compare prices
That's the intent - the merchant price links are affiliate links when possible.
pcarmichael··on Ask HN: Review my webapp PCPartPicker: pick parts, build a pc, compare prices
I've put in an incompatibility notice closer to the top that should be a bit more prominent - it's not perfect, but hopefully a little more visible until I can figure the right way to present it.
pcarmichael··on Ask HN: Review my webapp PCPartPicker: pick parts, build a pc, compare prices
Great suggestions, thanks. I'll definitely look into both.
pcarmichael··on Ask HN: Review my webapp PCPartPicker: pick parts, build a pc, compare prices
You're not blind. :) Once you click from the System Build view to choosing a component, there isn't a backlink to get back to your part list. That's a part of the navigation I couldn't figure out a clean way to present well, at least with the current design. You can, however, click on the System Build button along the top to get back to your part list from any page.
pcarmichael··on Ask HN: Review my webapp PCPartPicker: pick parts, build a pc, compare prices
Wow, lots of feedback - much appreciated.

Re: 1: This is becoming a common theme, so it's definitely something I need to address. I like your suggestions on how to break it down into more manageable sub-categories.

Re: 2: Changed it, thanks.

Re: 3, 4, 6, 8, 10: All definitely on the roadmap.

Re: 5: On the System Build page, there's a tab for viewing the price breakdown by merchant. Is that along the lines of what you were thinking? -- http://pcpartpicker.com/parts/partlist/by_merchant/

pcarmichael··on Ask HN: Review my webapp PCPartPicker: pick parts, build a pc, compare prices
Thanks for the feedback! I agree - the individual parts do need more information, and that's something I plan on augmenting. Regarding compatibility - I'm slowly getting to the point where I can guarantee compatibility. There's a lot of combinations and data points to fill in. It gets a little complicated with things like CPU/Motherboard compatibility, which can vary depending on bios revision. I've been working on back-filling that data both with web scraping (have to be careful - even some manufacturer spec pages have errors) and by hand where necessary. In time though I intend on filling in the gaps there.
pcarmichael··on Bike ride, accident, and ambulance trip tracked on Runkeeper
Completely agree on riding like you're a target. I ride according to the law and also as if I'm invisible to drivers. That paranoia has definitely kept me out of an accident several times.

One thing though - and it may seem counter-intuitive - is that riding on sidewalks is considerably more dangerous. I believe a 1985(?) study showed that it was roughly twice as dangerous, and another study (1998?) also showed an increase in risk. Granted there are always exceptions, but on average you're better off on the road.

pcarmichael··on Announcing Micro Instances for Amazon EC2
Yes, but only if the nodes are in the same region and availability zone. From amazon's pricing page [http://aws.amazon.com/ec2/pricing/]:

  There is no Data Transfer charge between Amazon EC2 and
  other Amazon Web Services within the same region (i.e.
  between Amazon EC2 US West and Amazon S3 in US West). Data
  transferred between Amazon EC2  instances located in 
  different Availability Zones in the same Region will be
  charged Regional Data Transfer. Data transferred between 
  AWS services in different regions will be charged as
  Internet Data Transfer on both sides of the transfer.
pcarmichael··on Ask HN: Share a gem. Teach me and you.
To add to this, use shower board from a hardware store. The cost is usually <$20 for a 4'x8' sheet. The quality varies but the price is hard to beat.
pcarmichael··on Build a $200 Linux PC
Thanks! I don't currently have Newegg prices yet, but I hope to add those soon. Their prices are usually competitive and they're known to run some pretty good deals from time to time.
pcarmichael··on Build a $200 Linux PC
Ok, I've added it to the overall CPU list: http://pcpartpicker.com/partscharts/cpu/overall-list/
pcarmichael··on Build a $200 Linux PC
Thanks! I'm glad you like it. It's still very much a work in progress - I was debating whether I should post the link or not given how much I left to do before it's really "ready".

For CPUs, were you looking for a price/core ratio?
