amanfredi··on Grad Student Rigs Cheap Alternative to $1,000 Air Purifiers in China
HEPA is only for particulate contaminants. At least some of the expensive filters have activated charcoal and other chemical filters.
amanfredi··on The Water-Repelling Surface That Lives Outside My Window
Yes indeed :)
amanfredi··on The Water-Repelling Surface That Lives Outside My Window
Hi Aatish! I enjoyed it quite a bit. The fibers on the bottom of the leaf may not be significant -- perhaps they are vestigial and only the upper ones provide an advantage.

Alternatively, heavy rain and wind can flip leaves upside down, blow plants over, and splash dirt and water up onto the underside of the leaves, so maybe it is an advantage for the whole leaf to shed water.

Yes, they have said it will be.
amanfredi··on It's A Terrible Time To Buy An Expensive House
In many places, homes available to rent are not and will never be comparable in quality to homes available to purchase.
amanfredi··on White Coke
It's easy to think that, but no. The materials will degrade and the data will become unreadable sooner than you think, probably on the order of 10s of years, depending on the manufacturing quality.
amanfredi··on Has The Cupcake Bubble Finally Popped?
I think the real problem with Crumbs cupcakes is that they are actually pretty bad...
amanfredi··on Amazon Will Pay Shoppers $5 to Walk Out of Stores Empty-Handed
Handling delivery of packages is sill a major annoyance of online shopping. I love Amazon but consumer-side logistics could use some serious improvement. The drive to reduce shipping prices as much as possible has definite downsides.

- Items consistently damaged/stolen during shipment. - Delivery of incorrect items/wrong address. - No place to leave packages during the day if you live in an apartment with no doorman. - Impossible to schedule delivery, especially before the first delivery attempt. It is unwise to order things while traveling. - Carriers lie about delivery attempts and times. - Distribution center for package pick up is 10 miles away and only open M-F 9-5.

amanfredi··on Yelp Files For $100 Million IPO
This isn't really fair. In Chrome DNS has practically been replaced by google search, and it's great.

Instead of typing yelp.com (or was it yelp.net? www.yelp.biz? http://www.yelp.info?) I can just type "yelp" and get where I'm going without having to remember the exact url and without getting an annoying error page if I make a typo. I suspect for many users even in other browsers the search box gets much more use than the URL box.

amanfredi··on How many resumes does it take to make an intern?
The sample size is so small that drawing any conclusions from this data seems suspect.

Percentage comparisons (hired/applied): 6% JoS fans 4.3% of Columbia job fair 2% Princeton job fair 1.7% of web search and 0% of everything else

amanfredi··on Dress.me: Because Guys Hate to Shop
We do give you the model's measurements but they don't necessarily mean much. The stylists for the models will pin the clothes to fit well so the pictures look good.

People who are models generally fall within a certain range of sizes, but it's still impossible to predict perfectly what will fit them, and you might not even have all the sizes available.

amanfredi··on Last.fm co-founder: Apple just fucked over online music subs for the iPhone
No, the writers at the WSJ are the producers of the original content. At some level, every producer is an aggregator. I don't think it's fair to categorically distinguish between the two, although you may disagree on the value of the aggregation.
amanfredi··on Chrome for a Cause
Terms of service:

"Please use our browser. We might donate some money to charity, if we feel like it."

amanfredi··on This year I mean it -- it's a bubble (2007)
In five years it seems that bloggers have about caught up to traditional media in reporting at the whims of PR firms.

Would anyone say there's a higher proportion of PR-resistant bloggers than newspapers or magazines?

amanfredi··on Re-entry to US without backscatter or pat-down
After all this, you don't think the TSA is strict on their policies?
amanfredi··on [dead]
Why is weapon in scare quotes in the title?
amanfredi··on Google.com has an animated logo using an HTML/JavaScript particle simulator
I really wanted to click on it, which was very frustrating.

Usually when there's a new logo you can click on it and instantly find out why it's there.

amanfredi··on Telecommuting Culture - What it tells me about your company
Supporting telecommuting workers from out of state can be a big financial hassle as it may be enough to establish nexus in the state, which will force your company to collect sales tax there.
amanfredi··on StarCraft 2: help us mourn the death of content freedom
I appreciate that in general this attitude has led to erosion of rights. However...

I don't see how anyone other than Blizzard has any right to free speech on their privately owned gaming platform.

Even if Blizzard has created a new medium of expression in Starcraft II maps, why should they should be compelled to enable the distribution of any map they don't like?

I understand that people may not like Blizzard's decision to moderate their platform, but it's a big stretch to say that they are trampling on our right to free speech. Is a newspaper trampling on your right to free speech by choosing which editorials to print?

amanfredi··on Wikileaks Must Be Stopped
You don't need privacy if you have nothing to hide, eh?
amanfredi··on What you say about others says a lot about you
I think the difference is more along the lines of:

- That person is wrong, they must be stupid.

- That person knows he's wrong and is just trying to further his own agenda.

- I think that person is wrong and they are either misinformed or know something I don't.

amanfredi··on Reality: Old Spice sales are actually up 107% in the last month
Can you explain this at all?
amanfredi··on Tweet Less, Kiss More
Twitter, texting, cell phones, etc. don't cause rudeness, they just make it more obvious.
amanfredi··on Razor Burn: A Flood of Fancy Shavers Leaves Some Men Feeling Nicked
I have a lot of thick facial hair and the disposable razors just weren't cutting it. I've switched to a straight razor with a DE for travel and when I'm in a hurry, and the difference has been amazing. The area on my neck where I used to constantly have ingrown hairs is finally smooth and happy.

I think there are four issues at play: - attention to shaving technique tends to be much less with a disposable, possibly due to ignorance - shaving cream from a can does a bad job of lubricating the face - disposable razors are poorly designed, with a gap between the razor and the skin, and are easily clogged with cut hair - the sharpness of disposable razor blades is essentially unknown

amanfredi··on Attack of the cosmic rays: Undetected memory errors can happen to you
It doesn't really matter if the errors were caused by cosmic rays or the ram failing -- it's still dangerous and relatively undetectable.
amanfredi··on Ask HN: Who is Hiring?
Glad you like our stuff; sorry you never got a callback! Our HR department was very disorganized for a while -- it should be a lot better now.

amanfredi··on After 15 years of practice..
We sang in church, and I took cello lessons and was involved in a choir, but neither of them actively played an instrument. My mother was also a good singer.
amanfredi··on After 15 years of practice..
As long as I can remember, I've been a good singer. I've also always enjoyed singing, so the thousands of hours of practice accumulated during childhood, in the car, in the shower, etc. didn't really seem like "hard work". I wouldn't say I've had to work to develop my singing ability in the same way Derek has.
