letney··on How we built Flow
...while I thought it would be covering Facebook's Flow project posted here a week ago: https://news.ycombinator.com/item?id=8625222
letney··on The Windows Incident – Day 0
While the submission title matches the article, it screams linkbait to me. I clicked fully expecting to read about a new 0 day exploit...
letney··on CVE-2014-7169: Bash Fix Incomplete, Still Exploitable
Yes, I got that too.

letney··on The Awful Reign of the Red Delicious
I absolutely love Envy apples!

They are very crisp and sweet without the tart flavor other crisp varieties seem to have. They also don't go brown after cutting for a very long time.

Definitely worth the slightly higher price in the supermarket. I very much miss them when they are out of season.

letney··on The unstoppable TI-84 Plus: How an outdated calculator still holds a monopoly
> Is that something I should pursue?

I can only offer an emphatic YES. I think that there are enough geeks out there that would like to see this monopoly broken that I predict a Kickstarter would be a rousing success.

letney··on Death by Inches: The battle over the metric system in America
> "you can't even represent 0.1 in IEEE floating point"

Not true, the IEEE 754-2008 standard provides a Decimal Floating Point specification in binary.

letney··on Death by Inches: The battle over the metric system in America
"fishes" refers to multiple species of fish, while "fish" is the correct plural form of a school of a single species.
letney··on IRS claims to have lost 2 years of Director's emails
> ...and you've saved money in the process too.

This discussion hearkens back to the current investigation into John Swallow, the former Attorney General of Utah who resigned less than a year into his term and is currently the subject of multiple investigations.

Swallow 'lost' over 1,700 emails from his time in office on his home computer. The state of Utah has spent over $100,000 to recover them (some successfully), see: http://www.sltrib.com/sltrib/news/57648883-78/swallow-sltrib...

letney··on Gamma Wave Brain Zaps Induce Lucid Dreaming
I too experienced a plethora of lucid dreaming through my early twenties. Sometimes I would have a few a night for weeks. They tapered off gradually and I have maybe a few a year now (I'm 35).

Many were tied with sleep paralysis, which didn't give me the fear that most people associate with it. Sometimes I could extract my preceptual self from my body and experience walking around the room in a weird lucid dream world. All while simultaneously being aware of my pysical body lying in bed.

I would love to have those dreams again.

letney··on The Pocket Handbook of Image Processing Algorithms in C (1993) [pdf]
20+ year C/C++ programmer here. I always use ++x unless the postfix version (x++) provides more succinct code.

The postfix operator can incur a temporary variable to be created by the compiler and thus make code slower.

letney··on Nginx has replaced Apache as the most used web server among the top 10,000 sites
Probably never. As any site in the top rankings is likely going to be using nginx as a reverse proxy to node.js.
letney··on Why is NaN not equal to NaN?
As a C/C++ and graphics programmer, I love NaN. It allows saving space by not having to carry an extra is_valid boolean for uninitialized values or regions of data that are masked.

For textures, they are great as they don't interpolate w/ nearby neighbors and properly discard fragments & vertices without the aforementioned cost of an extra boolean attribute.

letney··on Where Football Players Call Home
I came here to say the same.

As a resident of Hawaii it often peeves me to see it left out of so many geographic info-graphics.

Hawaii as a sizeable Polynesian pupulation, so my guess is that both the total and per-capita numbers for Hawaii are on the high end of the spectrum.

It's too bad this is not revealed in an otherwise great visualization.

letney··on Do you know your bitwise operators?
The work-around for 'x&(x-1)' I found is one-character longer: '(x&(~x+x+x))'
letney··on Poll: Do you have a Facebook account?
Yes, I've had one since early 2005 when a .edu email was required to signup.

I have 0 friends and the only content is a single status post of:

"I don't use facebook, please contact me via email".

letney··on Ask HN: Where do you spend Bitcoins?
Gyft.com is my go to place for instant conversion of BTC to a medium (a gift card) I can spend in my local Target or CVS Pharmacy. Their reward system rebates 3% of BTC purchases.
letney··on Wikileaks publishes 500k new Stratfor emails
If you are a DoD employee or contractor, then the answer is 'yes'.

letney··on Cruise Sheet: Find cruise deals
Yes. At the sit down dinners I often couldn't decide on an entree -- so I would just order both.

Drinks (including soda, coffee, and of course alcohol) are very much not free though. You are also not allowed to bring any alcohol on board.

Some cruises have begun charging "charging extra for new premium amenities such as fancy alternative restaurants" [1] -- but the run of the mill buffets are all you can eat and free.

letney··on Coinbase Halts Sales
They charge 1% on every buy & sell -- so I don't think they're losing money.
letney··on Cruise Sheet: Find cruise deals
No. Every US based cruise I've ever been on or heard about has free meals. Its common to hear people talk about gaining 10 lbs on a cruise because they ate so much.
letney··on Bitcoins reached $300
A "Satoshi" already has the common usage/definition of 0.00000001 BTC -- the current smallest denomination.

letney··on Bitcoin price reaches a record high for the first time since April
What's your source for the '...seizure of 5% of all Bitcoins recently'?

The FBI total seizure from Silk Road is 173,991 Bitcoins [1] -- which is about 1.45% of the Total BTC (11,954,825 [2])

letney··on FBI Says It's Seized $28.5 Million in Bitcoins From Ross Ulbricht
Your 0.7% figure is slightly off. The total number of Bitcoins to be mined is 21 million, putting the percentage at slightly more than 0.54% (114000/21000000).
letney··on How Bitcoin Could Become a Viable Currency
Ah, but that's improving rapidly. Coinbase does BTC->USD in less than 24 hours and USD->BTC instantly (with level 3 verified accounts).
letney··on The Coinbase iOS app has launched
Wow. This seems like big news in the Bitcoin world to me. This means Apple is giving the green light to Bitcoin related apps in the iTunes store.

I wonder if Apple will start allowing entirely phone-based wallet apps now...

letney··on Bitcoin Network Doubles to 2 PH/s in Four Weeks; the First 1 PH/s Took 4.7 Years
> the percentage doesn't seem to bring enough money compared to the cost of electricity for those machines.

That is entirely dependent upon the value of one bitcoin.

The transaction fees for a block go to the miner.

If bitcoin is actively used in 2140 when the issue of new coins ceases, the value of even small fractions of a coin will likely be very high.
